Increasing global temperatures are changing the migratory habits of some turtle, bird and fish species, according to the BBC. The little egret, the loggerhead turtle, and the red mullet prefer warm waters and are often found in lower latitudes. However, these species are now easier to spot near the British Islands. Global warming also causes the melting of ice caps, the habitat of polar bears and seals, and the rise of sea levels, destroying nesting sites for turtles. In some turtle species, the water temperature also affect the sex ratio of hatchlings, with warmer waters increasing the number of females.
Warmer global temperatures are likely to change the feeding habits of some insects, such as ants, grasshoppers and beetles, greatly increasing their appetites and population numbers. As plants tend to flower earlier when the global temperatures are warmer, bees, butterflies and other insects that feed on pollen and nectar of specific plants have changed their diets to survive. Warmer waters also shorten the first stages in the life cycles of some marine invertebrates, such as lobsters, reducing population numbers.
Although most mushrooms look like plants, they don't perform photosynthesis. Fungi are a separate kingdom of heterotrophic creatures, which also suffer the effects of global warming. In addition to growing faster and earlier in the year, some mushroom species produce a fruiting body twice a year and release less carbon dioxide through their respiration when temperatures are warmer.
Microscopy fungi and other heterotrophic microorganisms, such as bacteria and protists, are sometimes pathogens of plants and animals. Most pathogenic microscopic fungi attack invertebrates, other fungi and amphibian, which have lower body temperatures in comparison to mammals. Global warming can change the habits of these microorganisms, as they adapt to warmer temperatures and attack mammals, increasing fungal diseases in such animals.
