Coenagrionidae Coenagrionidae is a family of damselflies, also known as pond damselflies, in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 spec ...

Thermal adaptation

This genus's capacity for phenotypically plastic responses to the surface air temperature is important to species' ranges. These thermal responses will also decide a great deal of these species'

responses to climate change Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in ...
