Climate change is an increasing threat that scientists are trying to not only combat but prepare for future increases in temperature and rainfall. One of the effects of climate change is the warming of ocean and air temperatures. The sex of sea turtle offspring is determined by temperature during development. Temperature over 87° Fahrenheit will result in female offspring. In 3-5 sentences, describe how organisms like the sea turtle might adapt to the rise in ocean and air temperatures. In your explanation, describe the correlation between environmental factors and natural selection.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
