I came across this neat video summarizing a study that found some birds build nests near alligators to protect themselves from other predators. But the protection is not without a price.

A new study conducted by researchers at the University of Guelph found that the use of certain pesticides impacts wildflower pollination by bees. According to a quote by study author Nigel Raine, published in CBCNews, the use of neonicotinoid-type pesticides “modify the way in which information flows through the nervous system.” The research team found that bees gather pollen more frequently, but less efficiently, when exposed to the pesticide compared to […]
In a new study published in The Auk, scientists report that well-fueled older tiny Ruby-throated Hummingbirds (Archilochus colubris) might be capable of non-stop flights of over 4,000 kilometers, wind conditions permitting. They made this remarkable observation while studying birds from 2010-2014 as the animals made stopovers at a wildlife refuge during their annual migration to South America. In general, older birds not only showed up at the wildlife refuge in Alabama earlier than younger birds, they also tended […]
In a new study published in Physiological Genomics, researchers explored the role of genetics in the conformation of Tennessee Walking Horses. In other words, how close each animal they sampled looked to an “ideal” Tennessee Walking Horse. According to Kylee Jo Duberstein (Department of Animal and Dairy Science, University of Georgia), there are five criteria that are examined when evaluating the conformation of a horse. These include “balance, structural correctness, way of going, […]
A special thank you to reader Dr. Barbara Goodman, Professor of Physiology at Sanford School of Medicine of the University of South Dakota who sent me a story from The Scientist about sleep in animals complete with footage of a dolphin that was seen apparently “sleeping” (video posted on YouTube): Why do animals sleep? This is a question with many potential answers. It is known that birds and mammals experience slow-wave and rapid eye movement (REM) […]
Scientists from the National Oceanic and Atmospheric Administration (NOAA) think they have discovered a new species of octopus while exploring the ocean floor around Necker Island (near Hawaii). The octopus was found 4,290 meters deep. Interestingly, fins were absent from the pale octopus, which NOAA scientist Michael Vecchione noted was unusual for an octopus living at that depth. Moreover, its suckers were found to be in a single row on each of its […]
