Ecological Correlates of F***l Corticosterone Metabolites in Female Greater Sage-Grouse (Centrococercus urophasianus) 07/20/2021

Ecological Correlates of F***l Corticosterone Metabolites in Female Greater Sage-Grouse (Centrococercus urophasianus)

Congratulations to Dr. Cassandra Nuñez and colleagues for their new publication "Ecological Correlates of F***l Corticosterone Metabolites in Female Greater Sage-Grouse (Centrococercus urophasianus)". The authors evaluated the stress response associated with habitat use and corticosterone metabolite levels in f***s of female Sage-Grouse and observed that concentrations of corticosterone increased with home range size but decreased with reproductive effort and temperature. The data suggest that maintaining or improving habitats that promote smaller home ranges would likely lower the stress response in hens.

An Analysis of plant awareness disparity within introductory Biology textbook images 06/17/2021

An Analysis of plant awareness disparity within introductory Biology textbook images

Congratulations to the Sabel lab for their recent publication exploring how plants and animals are represented in introductory biology textbooks. Plants are critical to oxygen, carbon and water cycling, as sources of food and medicine, as well as raw materials for the production of clothing, habitats, and shelter. In spite of their importance, plants are often ignored in their environment, a tendency defined as "plant awareness disparity (PAD). In this paper, the authors analyzed images from introductory biology textbooks for biology majors to assess how often plants are used as models of biological concepts. You can read the paper by clicking on the link below. To learn more about the research in the Sabel lab, visit http://jaimelsabel.com/

Evolution in the Deep Freeze 06/17/2021

Evolution in the Deep Freeze

Professor Duane McKenna, Dr. Seunggwan Shin (former McKenna Lab postdoc, now Asst. Professor at Seoul National Univ.), and Dr. Richard Adams, a postdoc and Biological Data Scientist at FL Atlantic Univ., and Research Associate of the McKenna Lab, last week published a paper Fifty million years of beetle evolution along the Antarctic Polar Front in Proceedings of the National Academy of Sciences U.S.A., along with collaborators from the Scientific Committee on Antarctic Research. They demonstrate that some elements of Antarctic biodiversity are surprisingly rich and ancient (here, a diverse lineage of flightless beetles more than 50 million years old with African origins). Their work has relevance to climate change and diversification paradigms involving the Antarctic biota (unexpectedly, beetles diversified as the climate cooled in the Antarctic, in parallel with marine organisms and newly available data from other terrestrial organisms). Their work is also relevant to the evolution of insect-plant interactions (they show that insects evolved unusual diets in Antarctic environments that are depauperate of flowering plants), and specialized feeding habits (one weevil has evolved to inhabit the marine littoral zone and is still undergoing speciation).

Another publication from Dr. Jim Adelman and colleagues! Their paper "Oviposition response of monarch butterfly (Lepidoptera: Nymphalidae) to imidacloprid-treated milkweed." which investigates whether ovipositing monarchs discriminate against milkweed plants exposed to the neonicotinoid insecticide imidacloprid, either systemically or through foliar application.
