How animals get their stripes and spots
Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive......»»
The rise of color vision in animals: Study maps dramatic 100-million-year explosion in color signals
Colors are widely used in communication within and among animal species. For example, peacocks proudly display their vibrant tails, adorned with iridescent eyespots, to attract peahens for courtship. This is a classic example of sexual selection usin.....»»
Researchers discover genetic reason for the red, yellow and orange bills of Australian finches

Australian dragon study reveals surprising link between motor systems control and sleep rhythms
Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of animals, including worms, jellyfish, insects or cephalopods, and in all vertebrates, from fish to humans. Common characteristi.....»»
Ancient unicellular organism indicates embryonic development might have existed prior to animals" evolution
Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals......»»
"Shallow" sports and "deep" social hierarchies: Not all pecking orders are created equally

New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
Researchers are developing the next generation of sensors to improve horse welfare

Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»

A comparison of bat and bird wings reveals their evolutionary paths are vastly different
Bats are incredibly diverse animals: They can climb onto other animals to drink their blood, pluck insects from leaves or hover to drink nectar from tropical flowers, all of which require distinctive wing designs......»»
Nigeria"s last elephants: What must be done to save them?
Nigeria has a unique elephant population, made up of both forest-dwelling (Loxodonta cyclotis) and savanna-dwelling (Loxodonta africana) elephant species. But the animals are facing unprecedented threats to their survival. In about 30 years, Nigeria'.....»»
How researchers can maximize biological insights using animal-tracking devices
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell a deeper story about the lives of.....»»
Algae-jellyfish relationship provides insight on immune health
Marine animals like jellyfish, corals and sea anemones often live with algae inside their cells in a symbiotic relationship. The animals give the algae nutrients and a place to live; in return, algae give the animals some of the food they make from s.....»»
Study finds comb jellies can reverse age
A new article published in Proceedings of the National Academy of Sciences reveals the unprecedented ability for reverse development in a ctenophore, also called comb jelly. The findings suggest that life cycle plasticity in animals might be more com.....»»
