U.S. birds’ Eastern, Western behavior patterns are polar opposites

Avian functional diversity patterns in the Western U.S., where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high, according to new research.

Study Explores Link Between Shark Nose Shape, Size and Sensitivity of Smell

Differences in sharks’ olfactory systems are of interest not only because of their known incredible sense of smell but also because they have been around since before the dinosaurs. They managed to thrive in every known marine habitat for millions of years – their sense of smell may have been key. A study is the first to quantify olfactory organ morphology by examining rosette shape and other internal structures among a diverse set of shark species using dissections, phylogenetic comparisons, and a fairly new technique, called diffusible iodine‐based contrast‐enhanced computed tomography imaging. Results reveal that the organs did not change in shape or number of lamellae throughout the life stages, suggesting that olfaction is a key sensory modality throughout the life of elasmobranch fishes.

Brains and brawn helped crows and ravens take over the world

Crows and ravens are well known for their black color and the harsh “caw” sound they make. They are intelligent birds that use tools, solve complex abstract problems and speak a volume of words. But what is less well appreciated is how diverse they are. Their diversity is accompanied by their ability to live all over the world in a variety of habitats.

UTEP-led Research Team Aiming to Understand Impacts of Hybridization Awarded $1 Million NSF Grant

A team of researchers from multiple institutions led by Philip Lavretsky, Ph.D., assistant professor in The University of Texas at El Paso’s Department of Biological Sciences, was awarded nearly $1 million in funding from the National Science Foundation (NSF) to advance ongoing research to understand the adaptive impacts of hybridization between wild and domesticated animal populations.

Tweaks Behind the Rebirth of Nearly Discarded Organic Solar Technologies

A minuscule, counterintuitive chemical tweak is advancing an organic solar technology that was believed unviable.
