Arboreal locomotion a method known as parachuting, such as "Rhacophorus" (a "flying frog" species) that has adapted toe membranes allowing it to fall more slowly after leaping from trees. Many species of snake are highly arboreal, and some have evolved specialized musculature for this habitat. While moving in arboreal habitats, snakes move slowly along bare branches using a specialized form of concertina locomotion, but when secondary branches emerge from the branch being moved on, snakes use lateral undulation, a much faster mode. As a result, snakes perform best on small perches in cluttered environments, while limbed organisms seem to do best on
Introduced trout in lake ecosystems suitable food resources, are all factors that interact with fish introductions to influence impacts. Amphibian declines have become a worldwide issue that is most commonly attributed to chemical pollution, acid rain, ozone depletion, habitat destruction, as well as introductions of exotic species Recent studies have shown correlations of decline among amphibians to a chytrid fungus, which causes chytridiomycosis. The pathogen is one of many emerging infectious diseases that largely threaten amphibian populations, especially salamanders. Primarily spread through the import/export of live animals the threat lies when infected animals escape or are released into the wild. Copepods are diaptomids, or crustaceous
