Alyssa M.De La Torre, Giancarlo López-Martínez Abstract Hormesis occurs as a result of biphasic dose relationship resulting in stimulatory responses at low doses and inhibitory ones at high doses. In this framework, environmental factors are often studied to understand how this exposure benefits the animal. In the current study we used anoxia, the total absence…

Jacob B.Campbell, Giancarlo López-Martínez Published: March, 2022 Abstract The manipulation of oxygen to trigger the stimulatory response known as hormesis is an area of interest in insects that was born almost fifty years ago. Varying low-oxygen treatments have been investigated many times since with differing responses found; some hormetic/some harmful. In this review, we summarize…

Ellen Keaveny, Michael Dillon Published: September 24, 2022 Abstract For insects, the timing of many life history events (phenology) depends on temperature cues. Body size is a critical mediator of insect responses to temperature, so may also influence phenology. The determinants of spring emergence of bumble bee queens are not well understood, but body size…

Keaveny, E.C., Waybright, S.A., Rusch, T.W., and M.E. Dillon Published: February, 2022 Abstract Bumble bees thrive in cold climates including high latitude and high altitude regions around the world, yet cold tolerance strategies are largely unknown for most species. To determine bumble bee cold tolerance strategy, we exposed bumble bees to a range of low…
