Pond life
Pond life is an umbrella term for all life forms found in ponds. Although there is considerable overlap with the species lists for small lakes and even slow-flowing rivers, pond life includes some species not found elsewhere, and as a biome it represents a unique assemblage of species.
To survive in a pond, any organism needs to be able to tolerate extremes of temperature, including being frozen in ice and surviving complete drying out of the pond. Survival techniques include the production of resting eggs that can survive ice and desiccation, using the pond for only part of the life-cycle, and having overwintering stages such as turions buried in the mud.
Ponds are ephemeral in geologic time and are frequently man-made as remnants of clay digging, borrow pits or abandoned quarries. They may only exist for a few years in some cases. Organisms that favour living in ponds must have capabilities for reaching ponds, reproducing there and the capability to populate other ponds. Without these capabilities, they would not survive.[citation needed]
For many organisms including bacteria, fungi, protozoa, rotifers, bryozoa, cnidaria and small arthropods, the principal colonisation vector is wind-blown spores or eggs, often from drying muddy edges of one pond to another.
Other common vectors include birds carrying pond material and defecating seeds of plants. This is probably the most common transfer route for molluscs, annelids, planarian and plant vegetative fragments and probably the specialist water spider that lives underwater.
Insects typically find their own way by flying. This includes many of the pond specialist such as whirligig beetle, water boatman, water measurer and many types of mosquito, gnat and midge and even the heavy Dytiscus.
Ponds provide a useful resource for larger mammals, birds and plants. If unaffected by human activity, ponds are often surrounded by trees as the local water table is typically raised because of the pond water. These trees in turn provide nesting and feeding opportunities for many bird species. Ponds also support larger mammals including water shrew and water vole. Badger setts are commonly found in pond banks where the ground slopes, and other mammals such as foxes and domestic cattle and horses use ponds as a drinking water supply. All these animals and birds can also be vectors for pond-dwelling organisms.[citation needed]
