Adapting to rising temperatures

In a new review article published in Physiology, Dr. Jonathon Stillman from San Francisco State University explores how populations of animals and humans may respond to increasing frequency of heat waves. According to Dr. Stillman, the past decade has produced some of the hottest years on record, resulting in the loss of human and animal life. Both the length and intensity of these heat waves are expected to increase, which […]

Ants ‘nurse’ their injured

A study conducted at the University of Lausanne in Switzerland shows that Matabele ants, Megaponera analis, lick wounds their comrades sustain while hunting termites. It is thought that this “nurse”-like behavior may help prevent infection as ants receiving such care are more likely to survive: Sources: Youtube / New Scientist Frank ET, Wehrhahn M, Linsenmair KE. Wound treatment and selective help in a termite-hunting ant. Proceedings of the Royal Society B, DOI: 10.1098/rspb.2017.2457

Fasting as a survival strategy in animals

Although female northern elephant seals only typically deliver one pup, females will sometimes nurse offspring from other mothers as in this photo by Brocken Inaglory via Wikimedia commons. A situation like this would result in less milk available to each nursing pup. I just read an interesting paper published in Physiology. Animals periodically undergo periods of food deprivation such as during hibernation, mating, molting and migration. During these period of […]

Researchers discover new genes that protects water bears when they dry out

Water bears, aka tardigrades, are resilient little creatures. These microscopic animals can survive both freezing and boiling temperatures, radiation, high pressure, starvation, the vacuum of space and even desiccation. This last ability caught the attention of a team of researchers interested in how they are able to survive for years despite being completely dried out, an ability known as anhydrobiosis. Video by Daiki D. Horikawa, via YouTube. The team discovered special genes that […]
