Picture taken December 24th
(Disclaimer: the beach photos are still ongoing, but I thought I would take a break and show you a different ecosystem)
The photo above was taken at a pond in Desert Breeze Park, AZ, and depicts an American Coot. The American coot is a bird that, while resembles a duck, is actually a part of the rail bird family. These waterbirds often hang around ponds, and are a very adaptable species. Despite being of least concern (in terms of species endangerment), their population has recently decreased in the eastern side of the United States, largely due to threats that not only affect them, but also pond ecosystems (Source 1).
The American Coot is particularly susceptible to fire weather because wildfires can completely destroy its habitat, and decrease the land it has available for nesting and other purposes. While their population is decently stable now, this could potentially be a large problem in the future, as the increase in average annual temperature (due to climate change) is increasing the risk and chances of a wildfire (Source 2). The warmer seasons also pose a threat to their young, who cannot stand high heat (Source 1). Habitat destruction is also a problem in pond ecosystems in general, which can be caused by (Source 3):
• Pollution- Because ponds have smaller amounts of water compared to other aquatic ecosystems, it is much harder to recover from pollution damage since it can spread to the entire habitat so quickly. It can also be difficult for ponds to be cleaned, meaning pond water can be polluted for a long time.
• Human development- The development of human infrastructure often disrupts land by or on ponds (as the natural surroundings are replaced by more human ones). This effectively destroys their habitat.
• Increase in agriculture (Directly correlate with pollution)- Ponds have slowly decreased as more and more land is being set aside for agricultural production. In addition to this however, chemical fertilizers and pesticides are a huge threat to pond ecosystems, as they are heavy pollutants and can cause the eventual creation of dead zones, areas with oxygen hypoxia (lack of oxygen) and no animal or plant life.
