However, many amphibian declines or extinctions have occurred in pristine habitats where the above effects are not likely to occur. The causes of these declines are complex, but many can be attributed to emerging diseases, climate change, increased ultraviolet-B radiation, or long-distance transmission of chemical contaminants by wind.
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...
However, the speed of recent climate change is very fast. Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming ...
Reasons for amphibian declines are often termed ‘enigmatic' because the cause is unknown. Why some areas are affected by the fungus while others are not is not fully understood. Oscillating factors such as climate, habitat suitability, and population density may be factors which cause the fungus to infect amphibians of a given area.

Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming).

The latest climate assessment says Georgia will face mounting pressures for small-scale agriculture production from drought and extreme weather events. Climate disasters are costing Georgia ...
In Jacksonville, just south of the newly discovered Georgia mangroves, average winter temperatures have risen 3.4 degrees over the past half-century, according to the organization Climate Central.
Furthermore, trends reported in the Second National Communication of the UN Framework Convention on Climate Change show that average temperatures in Tbilisi, Georgia's capital, increased by 0.7 °C over the past century and by 0.5 °C in Eastern Georgia, but that there was a slight cooling in Western Georgia. Precipitation has increased in the ...
