How does an intersex bee behave?

(Smithsonian Tropical Research Institute) In a neotropical forest in Panama, an unusual bee was born. Its form was that of a male on one half and a female on the other half. Given the singularity of the occurrence, the group decided to describe an aspect of its behavior that hadn’t been previously studied in gynandromorphs: the circadian activity – the internal clock that drives an organism’s daily activities.

Pesticide seed coatings are widespread but underreported

(Penn State) Pesticide-coated seeds – including neonicotinoids – are increasingly used in the major field crops but are underreported, in part, because farmers often do not know what pesticides are on their seeds, according to an international team of researchers. “One of the most important findings of this study is that farmers know less about pesticides applied to their seeds than pesticides applied in other ways.”

Blinded by the light: How sensory pollution impacts animal survival

(Utah State University) A new paper provides a framework for understanding how light and noise pollution affects wildlife. The framework is the product of an effort among worldwide experts in ecology and physiology and reveals the presence of “sensory danger zones,” or areas where sensory pollutants influences animal activity. For example, artificial lights cover the glow of the moon, preventing birds or insects from detecting it. “From a conservation biology point of view, we don’t know how to mitigate the effects of sensory pollution if we don’t know what the pathway of harm is.”

Winner of ISU Three Minute Thesis is grad student who studies bees

(videtteonline) The Three Minute Thesis is a research communication competition that challenges master’s and Ph.D. students to describe their research topic and its significance in just three minutes to a general audience. This year’s first-place winner is Austin C. Calhoun, whose thesis is focused on the interactive impact of a fungicide and parasite on bumble bee health.
