Animal physiology is the scientific study of the life-supporting properties, functions and processes of animals or their parts. The discipline covers key homeostatic processes, such as the regulation of temperature, blood flow and hormones.
Animals detect microbiomes through smell, aiding communication, group recognition, and behavior. Here with Drosophila model, the authors show that airway and gut cells can sense microbiome-emitted scents independently of smell, promoting host growth.
Arthropods typically possess two eye systems—one pair of compound eyes and ocellar median eyes. Pygmaclypeatus daziensis, a Lower Cambrian arthropod, is equipped with two pairs of different compound eyes—ventrally stalked, movable compound eyes and dorsally, trilobite-like sessile ones.
Reduced human mobility during the pandemic will reveal critical aspects of our impact on animals, providing important guidance on how best to share space on this crowded planet.
