Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...ns the respiratory pattern of insects in different environments in ways that previous models can't." Two previous models for explaining why insects punctuate their breathing with periods of closure are (1) such discontinuous breathing reduces water loss and (2) it enables insects to rid their bodies of carbon di...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

... along separate paths, each adapting to the unique environments created by large scale climate change. "There are really dramatic morphological and physiological adaptations" to the new environments, Kingsley said. For example, "sticklebacks vary in size and color, reproductive behavior, in skeletal morphology,...
