Climate change downsizing plants and animals
When it comes to ClimateWatch, timing is everything. We are asking you to record observations like calling and nesting that indicate the timing of reproductive cycles to discover how climate change is shifting these events. However, Dr Jennifer Sheridan and Dr David Bickford at the National University of Singapore have found climate change is reducing the size of many animal and plant species.
"For cold-blooded animals, including insects, reptiles and amphibians, the impact is direct: experiments suggest that an upward tick of 1°C translates into roughly a 10 per cent increase in metabolism, the rate at which an organism uses energy. That, in turn, results in downsizing."
