Gee's golden langur geographic range

Gee's golden langur (Trachypithecus geei), also known as simply the golden langur, is an Old World monkey found in a small region of Western Assam, India and the neighboring foothills of the Black Mountains of Bhutan. Long considered sacred by many Himalayan people, the golden langur was first brought to the attention of the Western world by the naturalist Edward Pritchard Gee in the 1950s. Adult males have a cream to golden coat with darker flanks while the females and juveniles are lighter. The golden langur has a black face and a long tail up to 100 cm (39 in) in length. It lives in high trees and has a herbivorous diet of fruits, leaves, seeds, buds, and flowers. The average group size is eight individuals, with a ratio of several females to each adult male. It is one of the most endangered primate species of India and Bhutan.

In 2008–09, there were 6,000 golden langurs in India, which has grown to 7,396 by 2020–21.[4]

Discovery and etymology

[edit]

The earliest record of the golden langur is in an 1838 paper by Robert Boileau Pemberton which states that "Griffith observed these monkeys near Tongso in Central Bhutan."[5][6] However, since Pemberton's work was lost and not rediscovered until the 1970s, the scientific discovery of the golden langur unfolded differently. In 1907, Edward Oswald Shebbeare—who was out with some hunters and forest rangers—reported seeing a "cream coloured langur" in the vicinity of the Jamduar.[7][nb 1] However, neither a photograph nor a live or dead specimen was presented at that time. The first reference to the golden langur in print, as an animal of unidentified taxonomic status, was in a 1919 publication that stated: "Pithecus sp? – A pale yellow coloured langur is common in the adjoining district of Goalpara (Assam). Jerdon reported one from Terai, the adjacent district on the (west) side, which Blanford suggested might be P. entellus."[8][9]

In February 1947, in the Forest Rest House visitors' book in Raimona, a few miles south of Jamduar, C. G. Baron reported seeing some langurs whose "whole body and tail is one colour – a light silvery-gold, somewhat like the hair of a blonde." A year later, back in Jamduar, H. E. Tyndale, a tea planter, reported seeing "Sankosh cream langurs."[9] However, it wasn't until a few years later that a focused effort to identify the golden langur was mounted by Gee, who traveled back to Jamduar in November 1953. His team was able to observe three groups of golden langurs, all on the east bank of the Sankosh River. The first group was observed on the Bhutan side of the border; the second group, a large one of 30 to 40 individuals, a mile north of Jamduar on the Indian side; and a third group four to five miles (6.44 km to 8.05 km) south near Raimona. Colour movies of the second group were made by Gee.[9]

In August 1954, Gee reported his findings to an expert at the Zoological Society of London, who advised that the golden langur might be a new species. In January 1955, Gee also reported his results to the Zoological Survey of India (ZSI) and, after showing his movies of the golden langurs, suggested that Jamduar be included in the then-upcoming ZSI survey of that region.[10] The suggestion received the support of Dr. Sunder Lal Hora, then Director of ZSI, and later that year six specimens of the golden langur were collected by the survey party.[9] The following year, Dr. H. Khajuria, a taxonomist who studied the specimens, described the new species naming it Presbystis geei in honour of Gee.[11][nb 2]

Taxonomy

[edit]

There are two subspecies of this species:[1]

  • Trachypithecus geei geei Khajuria, 1956
  • Trachypithecus geei bhutanensis Wangchuk, 2003[12]

The subspecies are separated by a geological fault in the Himalayas called the Main Frontal Thrust. T. g. bhutanensis occurs in the northern part of the species range in Bhutan and T. g. geei is found in the south of Bhutan and Assam in northern India.

In Bhutan, it has hybridised with T. pileatus, the capped langur.[13][14] This is believed to be due to the construction of permanent bridges across the Chamkar River, a tributary of the Mangde River which separates the two species.[15]

Physical description

[edit]
Closeup of face

In online viral imagery of this species, many commentators have noted that its uncanny gaze appears remarkably human.[16] This is likely due to the light sclera in its eyes, a feature seen in some great apes, including humans.[17]

The coat of the adult golden langur ranges from cream to golden, on its flanks and chest the hairs are darker and often rust coloured while the coats of the juveniles and females are lighter, silvery white to light buff.[18] The coat changes color seasonally, from white or cream coloured in the summer to dark golden or chestnut in the winter. Their long whiskers protect their eyes from rain during monsoon.[citation needed] The golden langur has a black face and a large whorl of hair on its crown.[11]

Gee's golden langur exhibits sexual dimorphism. Males are larger and more robust than females. Adult males weigh 10.8 kg (24 lb) on average and adult females weigh 9.5 kg (21 lb).[19] The length of the head and body ranges from 50–75 cm (20–30 in),[20] while the relatively long tail is 70–100 cm (28–39 in) in length.[12][20]

Distribution

[edit]

Gee's golden langur is found in an area of approximately 30,000 square kilometres (12,000 sq mi), much of which is unsuitable habitat,[21] bounded on the south by the Brahmaputra River, on the east by the Manas River, on the west by the Sankosh River, in Assam, India, and on the north by the Black Mountains of Bhutan.[22] These biogeographical barriers are believed to have led to the radiation of species from the closely related capped langur (Trachypithecus pileatus).[23] There are two primary sub-populations fragmented by the National Highway 27. The northern sub-population occupies the western portion of the Manas National Park, extending from the Sankosh River to the Manas River along the northern side of National Highway 27 and State Highway 2, reaching the India-Bhutan border. Conversely, the southern sub-population is situated along the southern side of NH27, extending to the Brahmaputra River. Population estimates of the 2020–21 survey, indicate a larger northern population, totaling 5,566 individuals distributed across 534 groups and 23 lone males. In contrast, the southern fragmented population consists of approximately 1,830 langurs organized into 173 groups and eight lone males. Notably, the Ripu Reserve Forest hosts the highest number (2,847 individuals) within the northern sub-population, while the Chakrashila Wildlife Sanctuary in Kokrajhar district harbors the most significant number (838 individuals) within the southern fragmented range.[4]

In 1988, two captive groups of Gee's golden langur were released into the wild in Tripura state in north-eastern India, an area outside of their natural range.[24] One of the groups, released into Sepahijala Wildlife Sanctuary, survives and has adapted to the wild.[25]

Behavior and ecology

[edit]

For the most part, the langur is confined to high trees where its long tail serves as a balancer when it leaps across branches. During the rainy season it obtains water from dew and rain-drenched leaves. Its diet is herbivorous, consisting of ripe and unripe fruits, mature and young leaves, seeds, buds and flowers. It generally lives in troops of about 8, with a ratio of several females to each adult male. The smallest golden langur troop was composed of four individuals, while the largest had 22, giving an average value of 8.2 individuals per troop. The adult sex ratio was 2.3 females to every male, although the majority of groups had only one adult male.[26]

Conservation

[edit]

Gee's golden langur is currently endangered with a decreasing population trend; the total population of mature adults has been estimated as 6000–6500.[27] It is one of the most endangered primate species of India and Bhutan.[28] In India, 93% of the population is found in forest reserves (Chirang, Manas, and Ripu) and the western part of Manas National Park, and the remaining occur in several small isolated fragments.[14] The population has declined by more than 30% in the last 30 years and is expected to decline further shortly. Golden langurs are protected by law in their range. The species is listed in Appendix I of CITES,[29] and in Schedule I of both, the Wildlife Protection Act, 1972 of India,[30] and the Forest and Nature Conservation Act of Bhutan, 1995.[31]

Within India

[edit]

On 5 June 2019, the district authorities of Bongaigaon district in Assam launched a project under the MGNREGA to plant guava, mango, blackberry and other fruit trees to ensure that the resident golden langurs of the Kakoijana reserved forest do not have to risk their lives to find food. Several golden langurs have died due to electrocution and in road accidents while looking for food beyond the reserve forests.[32] In 1988, two captive groups of golden langurs were released into two protected areas of the western region of the state of Tripura, India. As of 2000, one of these groups, consisting of six (and possibly eight) individuals in the Sepahijala Wildlife Sanctuary, had survived.[24] The relative death of infants and juveniles indicates a declining population with the habitat being degraded by human activity. A fragmented but protected population in a rubber plantation in the Nayakgaon, Kokrajhar, district of Assam increased in population from 38 individuals in 1997 to 52 in 2002. The population has also adapted to feeding on dry rubber seeds.[33]

View on Grokipedia
from Grokipedia
Gee's golden langur (Trachypithecus geei) is an endangered in the subfamily, endemic to the tropical and subtropical moist broadleaf forests of western , , and southern , where it inhabits elevations from near to 3,000 meters. Known for its striking cream-to-golden fur that darkens on the flanks and chest, with a black face framed by a light-colored eye ring, it is a primarily arboreal , feeding on leaves, fruits, seeds, buds, and flowers, supplemented occasionally by and lichens. Discovered in 1953 by Indian naturalist E.P. Gee during a survey in , the species was formally described in 1956 and named in his honor, highlighting its restricted range and unique adaptations to canopy living. Adults are small to medium-sized, with head-body of 50–75 cm and of 70–100 cm, males slightly larger than females. in multi-female, multi-male troops of 5–50 individuals, often led by a dominant , exhibiting diurnal with activities centered on , grooming, and territorial vocalizations, including loud calls to communicate across fragmented habitats. is matrilineal, with females remaining in natal groups and males dispersing at maturity, and troops have home ranges of 0.3–0.5 km². The species' conservation status is Endangered under the IUCN Red List (last major assessment 2015, confirmed in 2025), driven by habitat destruction from deforestation, agriculture, and human encroachment, which has fragmented its range into isolated subpopulations and led to ongoing declines. Recent surveys estimate approximately 7,396 individuals in India as of 2024 and around 2,500 in Bhutan as of 2019, totaling around 9,900 globally. Conservation efforts, including protected areas like Manas National Park and Chakrashila Wildlife Sanctuary in India, and Jigme Singye Wangchuck National Park in Bhutan, alongside community-based initiatives to mitigate human-wildlife conflict, have stabilized some populations but ongoing threats persist.

Discovery and taxonomy

Discovery and etymology

Gee's golden langur was first brought to the attention of the in 1953 by British naturalist and conservationist Edward Pritchard Gee during an ornithological survey in the subtropical forests of western , , along the eastern bank of the near the border. Gee, who was also a tea planter and wildlife photographer, observed troops of these strikingly golden-furred primates and captured the first photographs and film footage of them, recognizing their distinctiveness from known langur species. Although local reports of golden-colored monkeys in the region dated back to at least 1907, earlier sightings had been sporadic and often dismissed or misidentified, delaying formal acknowledgment. The ' novelty was publicly announced by Gee in 1953, highlighting its limited distribution and unique appearance, which set it apart from more widespread langurs like the (Trachypithecus pileatus), with which it was initially confused due to superficial similarities in body structure and habitat overlap. This announcement spurred further investigation, culminating in its formal scientific description in 1956 by Indian zoologist Harbans Lal Khajuria, who named it Presbytis geei based on specimens collected from the type locality near Jamduar Forest Rest House in Assam's . Khajuria's description emphasized the primate's vibrant dorsally golden pelage, contrasting sharply with its darker underparts, solidifying its status as a distinct . The common name "Gee's golden langur" directly honors E. P. Gee's instrumental role in its discovery and documentation, reflecting his broader contributions to Indian . The binomial Trachypithecus geei, following its later taxonomic reclassification from Presbytis to the genus Trachypithecus (a group encompassing Asian leaf monkeys), incorporates the specific epithet "geei" as a tribute to Gee, while the genus name derives from "trachys" (rough) and "pithekos" (monkey), alluding to the coarse fur texture typical of these folivorous .

Taxonomy and subspecies

Gee's golden langur (Trachypithecus geei) is an classified in the order , family Cercopithecidae, subfamily , and genus Trachypithecus. This placement reflects its membership among the leaf-eating colobine monkeys, characterized by specialized digestive adaptations for folivory, within the diverse Old World primate radiation. A , Trachypithecus geei bhutanensis, was proposed in 2003 from southern based on ecological, morphological, and preliminary phylogenetic data distinguishing it from the nominate form Trachypithecus geei geei in western , ; however, its validity is not recognized by the IUCN due to non-compliance with (ICZN) rules. These forms are geographically separated primarily by the , with the Bhutanese population occupying higher elevations in the Black Mountains and additional barriers including the Aie and Champabati Rivers. Phylogenetic analyses, including mitochondrial DNA sequencing and mitogenomic studies up to 2020, affirm T. geei as a monophyletic species within the genus Trachypithecus, which encompasses around 20 Asian colobine species divided into four groups. Genetic evidence highlights its close affinity to species like the capped langur (T. pileatus), with divergence estimates placing the T. geei lineage as distinct and endemic to the Indo-Bhutan border region, underscoring its evolutionary isolation.

Physical characteristics

Appearance and morphology

Gee's golden langur is readily identifiable by its distinctive cream-to-golden , which serves as effective amid the sunlit canopy of its . This darkens on the flanks and chest, while the face remains hairless and black, contrasting sharply with the lighter body coat; the hands, feet, and tail tip are also black. Seasonal variations occur, with the darkening to golden-chestnut in winter and lightening to more cream-colored in summer. As an arboreal species, the golden langur possesses several morphological adaptations for life in the trees, including elongated limbs that facilitate agile leaping and brachiation between branches, prominent ischial callosities that provide padding for prolonged sitting on limbs, and a that aids in balance during movement. The dental formula follows the typical colobine pattern of 2.1.2.3, suited to its folivorous diet. The face features hairless black skin surrounding the eyes and mouth, enhanced by prominent white eye rings that accentuate facial expressions and play a role in within social groups.

Size and sexual dimorphism

Gee's golden langur (Trachypithecus geei) displays moderate , characterized primarily by differences in body size and robustness between males and females, while fur coloration remains similar across sexes. Adult males are larger overall, with head-body length of 51–68 cm and tail length of 78–102 cm, weighing 9–11 kg, while females are slightly smaller at 49–58 cm head-body, 74–92 cm tail, and 7.5–9.5 kg, reflecting the species' adaptation to arboreal life where size influences mobility and efficiency. Males exhibit more pronounced facial crests and larger canine teeth, aiding in intra-group interactions, though both sexes share the characteristic cream-to-golden that varies seasonally in hue. Females, while smaller, maintain comparable pelage patterns, ensuring in their forested . Growth patterns in juveniles highlight early developmental changes, with infants born possessing lighter, often white or pale fur that darkens progressively to the adult golden coloration over 6–12 months, coinciding with increased mobility and integration into .

Distribution and habitat

Geographic range

Gee's golden langur (Trachypithecus geei) is endemic to the Indo-Bhutan , occurring in a narrow belt of western , —primarily in the districts of and —and the southern foothills of 's Black Mountains. The species' distribution is confined between the to the west, the to the east, and north of the in , while in it spans elevations from near sea level to about 2,600 m across southern districts including Dagana, Tsirang, Sarpang, and others. The current area of occupancy is estimated at 4,300–4,400 km² (as of 2020), severely fragmented into isolated pockets separated by agricultural lands and human settlements. Historically, the range was more extensive, encompassing larger contiguous forests along the border prior to widespread 20th-century for and development. No range expansions have been recorded in recent decades; comprehensive surveys conducted through 2024 across the known distribution confirm the species' absence outside core protected areas such as and in , and Jigme Singye Wangchuck National Park in .

Habitat preferences

Gee's golden langur (Trachypithecus geei) primarily inhabits subtropical and tropical moist broadleaf forests, encompassing , semi-evergreen, dipterocarp, riverine, and moist types. These forests provide the dense, continuous canopy essential for the species' , enabling movement through brachiation and leaps between tall trees. The langur requires such uninterrupted canopy cover to avoid ground exposure, as it is highly vulnerable to predators when descending. Key habitat features include tall trees that support folivory, such as and species, which offer abundant leaves, fruits, and buds. Riverine corridors along major waterways, like those in the , serve as critical connectivity zones, facilitating dispersal and between forest patches. While the species occasionally ventures into adjacent savannas or open areas near rivers, it largely avoids such habitats due to the lack of sufficient canopy and higher predation risks. Elevation preferences vary across its restricted range in western , , and southern , spanning from near to over 2,600 meters. In , populations favor lower elevations (100–1,000 m) with denser, lowland and semi- forests, while in , they occupy higher altitudes (up to 1,800–3,000 m) in mixed -deciduous broadleaf forests. This altitudinal gradient reflects adaptations to varying forest compositions, with higher sites featuring more temperate influences and admixtures.

Behavior and ecology

Social structure and behavior

Gee's golden langurs (Trachypithecus geei) exhibit a complex centered on multi-male, multi-female groups ranging from 5 to 50 individuals, with average sizes of 8–11 members depending on quality. These groups typically consist of one dominant leading several females and their offspring, though multi-male units occur, particularly in larger or protected habitats. All-male bands comprising 2–5 individuals and solitary adult males are commonly observed, as dispersing males leave natal groups to avoid or . Grooming and allogrooming represent the primary affiliative behaviors, reinforcing bonds among females and between mothers and infants during midday rests. Vocalizations play a crucial role in communication and territorial maintenance; adult males emit loud whoops to advertise presence and deter rivals, while barks serve as alarm calls against predators or intruders. Groups are non-territorial, with minimal over resources, though vocal displays facilitate intergroup communication. As strictly diurnal and arboreal , golden langurs spend the majority of their active day—approximately 70%—, , and traveling through the forest canopy via leaps and quadrupedal locomotion. Juveniles frequently engage in play behaviors, such as chasing and mock fighting, which help develop motor skills and strengthen peer bonds within the group. Group sizes tend to be larger in continuous, protected forests compared to fragmented s, reflecting the impact of habitat quality on .

Diet and foraging

Gee's golden langur (Trachypithecus geei) is primarily folivorous, with leaves forming the bulk of its diet, typically comprising 50-70% of daily intake across young and mature varieties from a diverse array of plant . Fruits and seeds contribute substantially as secondary food sources, accounting for approximately 15-25% of the diet, while flowers add another 8-10%. Bark, twigs, and other vegetative matter supplement the diet, with occasional opportunistic consumption of , lichens, , and such as and snails providing protein during seasonal availability. The species exhibits selective strategies, prioritizing nutrient-rich patches within the forest canopy where it progresses as a cohesive group, spending 12.8-33% of its daily activity on feeding. This arboreal allows efficient exploitation of upper canopy layers, with individuals using dexterous hands to manipulate foliage during bimodal diurnal feeding peaks. Social coordination facilitates group-level decisions on foraging routes, minimizing energy expenditure while maximizing access to preferred foods. Dietary composition shows seasonal shifts, with increased reliance on fruits and flowers during the period when availability peaks, transitioning to a higher proportion of mature leaves in the to cope with resource . These adaptations are supported by a specialized system, featuring a multi-chambered harboring symbiotic microbes that break down fibrous for nutrient extraction.

Reproduction and life cycle

Gee's golden langurs exhibit a mating system characteristic of many colobine primates, with social groups typically comprising one adult male and multiple adult females, facilitating polygynous or potentially polygynandrous mating within the group, though detailed observations remain limited. Breeding occurs throughout the year, but mating activity peaks during the drier months from May to November, with births most common in the late monsoon and early winter periods when food resources are more abundant. The gestation period lasts approximately 180–200 days, after which females usually give birth to a single infant; twins are rare. Newborn infants cling to their mother's ventral surface for the first few months, receiving from her, including and grooming. Allomothering by other females in the group is common, providing additional protection and assistance in carrying and defending the young, which helps enhance survival in their arboreal . typically occurs between 10 and 14 months of age, after which juveniles begin independently but remain closely associated with the group. is attained by females around 4–5 years and by males at 5–7 years, marking the point at which they may participate in reproductive activities or disperse to form new groups. In the wild, is estimated at 20–25 years, though precise data are scarce due to the ' endangered status and challenging field conditions. has been documented in recent observations, often perpetrated by incoming males to accelerate the return of females to estrus and increase their own reproductive opportunities. This behavior, while rare compared to other langur , underscores the pressures of male turnover in social groups.

Conservation

Status and population

Gee's golden langur (Trachypithecus geei) is classified as Endangered on the since 1986, with a continuing decreasing population trend due to and loss. It is listed under Appendix I of the Convention on in Endangered Species of Wild Fauna and Flora (), which bans international commercial trade in the species. In , where the majority of the population resides, it receives the highest legal protection as a Schedule I species under the () Act, 1972. A 2024 survey estimates 7,396 total individuals in ; a 2019 survey estimates 2,439 in , for a global total of approximately 9,835 individuals, with mature individuals comprising roughly half due to high juvenile mortality. Approximately 75% of the population is in . The population is severely fragmented into at least 19 isolated subpopulations, including 2 major ones in (northern extended and southern fragments) comprising over 700 groups. Recent surveys indicate population stability or increases in protected areas, though the overall trend remains decreasing per IUCN due to ongoing fragmentation. No viable meta-population connectivity exists among fragments, limiting natural dispersal and recovery potential.

Threats

The primary threats to Gee's golden langur (Trachypithecus geei) stem from extensive , driven largely by for , tea plantations, and infrastructure development, particularly in the species' core range in , . These activities have resulted in the loss of at least 50% of the langur's original , severely reducing available forest cover essential for their arboreal lifestyle. Between 1989 and 2000 alone, massive habitat clearance fragmented the landscape, confining populations to isolated patches and exacerbating vulnerability to environmental changes. Habitat fragmentation and subsequent isolation pose significant risks, including increased within small, disconnected groups and heightened human-wildlife conflict. In fragmented areas, langurs often venture into agricultural fields to raid crops, leading to retaliatory killings by local communities and further population declines. At least 19 such isolated pockets now support the species, a stark contrast to its formerly continuous distribution, which limits and reduces overall . Historical estimates indicate a decline of over 50% in the past three generations (to 2015), though recent surveys show stabilization or increases in protected areas in . Poaching and hunting, while less prevalent than habitat loss, remain concerns, with individuals occasionally targeted for bushmeat or use in traditional medicine. Such direct persecution, combined with indirect threats like snares set for other species, further endangers small populations in accessible forest edges. Additionally, proximity to human settlements in degraded habitats raises the risk of disease transmission from humans to langurs, though specific outbreaks have not been widely documented.

Conservation measures in India

Gee's golden langur is protected under Schedule I of the Wildlife (Protection) Act, 1972, which prohibits hunting, trade, and , with strict penalties for violations. Enforcement efforts in protected areas have helped mitigate threats like and encroachment, contributing to population stabilization in key sites. Major protected areas in India harboring the species include the Manas Tiger Reserve (part of the Manas Biosphere Reserve), , and Kakoijana Reserve Forest, which together support a substantial portion of the Indian population estimated at 7,396 individuals as of 2024. The Manas Tiger Reserve holds the largest concentration, with approximately 5,566 langurs, benefiting from patrols and habitat management. supports about 558 individuals across 72 groups, while Kakoijana Reserve Forest has around 489 langurs in 45 troops, with ongoing monitoring to address fragmentation. Conservation programs have focused on surveys, community involvement, and habitat restoration. The Indo-US Primate Project conducted baseline surveys in the 1990s, including a 1997 assessment that informed subsequent monitoring and estimated initial population sizes. Building on this, the Golden Langur Conservation Project, initiated in 1997 by Community Conservation Inc., promotes community-based efforts such as alternative livelihood programs, control, and to restore degraded forests. These initiatives have facilitated corridor creation through canopy bridges and meta-population to connect fragmented habitats, aiding and reducing road mortality. Captive breeding efforts are centered at the Assam State Zoo cum Botanical Garden in , where the launched a program in 2011 to bolster and support potential reintroductions. Captive breeding efforts continue at the Assam State Zoo cum Botanical Garden, with programs established in 2011 to support , though current population numbers are not publicly detailed.

Conservation measures in Bhutan

Bhutan's conservation efforts for Gee's golden langur focus on protected areas that safeguard approximately 25% of the global population based on 2019 estimates of 2,439 individuals in . and National Park are critical strongholds, covering extensive semi-evergreen and mixed-deciduous forests essential for the ' survival. These parks, spanning over 2,700 km² combined, host the majority of Bhutan's langur population through strict habitat protection and monitoring. Community forestry initiatives in Bhutan actively integrate langur habitat by empowering local groups to manage forests sustainably, reducing encroachment and promoting restoration activities that benefit primate corridors. This approach aligns with broader national policies under Bhutan's biodiversity conservation framework, which constitutionally requires at least 60% forest cover nationwide, supported by regular anti-poaching patrols in protected areas to combat illegal hunting and trade. Ecotourism in generates substantial revenue, funding habitat restoration and community education programs that mitigate human-wildlife conflicts. In 2025, launched the Golden Langur Conservation Strategy and Action Plan (2025–2035), allocating Nu. 120.8 million for habitat restoration and conflict mitigation. An updated population survey for is needed. Transboundary cooperation with , formalized through a 2020 under the Transboundary Manas Conservation Area, facilitates joint patrols and habitat connectivity across borders, contributing to overall population stability.
