In their study, reported in the Journal of Experimental Biology, the group tested the ability of two captive bottlenose dolphins to sense a small electric field. https://phys.org/news/2023-12-bottlenose-dolphins-electric-fields.html Plants & Animals Sun, 03 Dec 2023 08:20:01 EST news620648234 Citizen scientists help discover new mantis species James Cook University researcher Matthew Connors has discovered two new praying mantis species with the help of citizen scientists.

But the whiskers fall out soon after birth, leaving the youngster with a series of dimples known as vibrissal pits. Recently, Tim Hüttner and Guido Dehnhardt, from the University of Rostock, Germany, began to suspect that the dimples may be more than just a relic. https://phys.org/news/2023-11-bottlenose-dolphin-weak-electric-fields.html Plants & Animals Ecology Thu, 30 Nov 2023 18:00:01 EST news620582542 New study offers cautious hope about the resilience of redwoods New research from Northern Arizona University has explained coast redwood's remarkable ability to recover from very severe fire, a rare sign of optimism amid a landscape increasingly scarred by severe fires. https://phys.org/news/2023-11-cautious-resilience-redwoods.html Plants & Animals Ecology Thu, 30 Nov 2023 17:31:03 EST news620587861 Research suggests sentinel warning calls may be universally understood across continents Animals often use vocalizations to warn of nearby danger to others. While this information is generally intended for members of the same species, other species can eavesdrop on the warnings to use the information for their own benefit. Sentinels are animals that have warning calls so widely understood by others that those other species will form groups with them, relying on the sentinels to provide warnings of danger. https://phys.org/news/2023-11-sentinel-universally-understood-continents.html Plants & Animals Ecology Thu, 30 Nov 2023 15:16:55 EST news620579812 Penguins snatch 11 hours of sleep through seconds-long micronaps In humans, nodding off for a few seconds is a clear sign of insufficient sleep—and can be dangerous in some situations, such as when driving a car. https://phys.org/news/2023-11-penguins-hours-seconds-long-micronaps.html Plants & Animals Thu, 30 Nov 2023 15:10:30 EST news620579424 Migratory songbird study finds link between white tail spots and longevity A new study of a migratory songbird shows that individuals with average-sized white tail spots—a trait that is critical to successful foraging—live longer than individuals with more extreme amounts of white in the tail. https://phys.org/news/2023-11-migratory-songbird-link-white-tail.html Plants & Animals Ecology Thu, 30 Nov 2023 13:18:51 EST news620572729 Are dogs or cats more skilled in relying on human pointing gestures?

ROP proteins, a group of plant-specific proteins, are known to control plant tissue formation. Now, Hugh Mulvey and Liam Dolan at the GMI show that ROP proteins evolved at the transition between unicellular and multicellular plant life.
