Microclimate Temperatures Impact Nesting Preference in Megachile rotundata (Hymenoptera: Megachilidae)
Elisabeth Wilson, Claire Murphy, Joseph Rinehart, George Yocum, Julia Bowsher Abstract The temperature of the nest influences fitness in cavity-nesting bees. Females may choose nest cavities that mitigate their offspring’s exposure to stressful temperatures. This study aims to understand how cavity temperature impacts the nesting preference of the solitary bee Megachile rotundata (Fabricius) under field…
Cryopreservation of seminal vesicle derived spermatozoa from Bombus impatiens and Apis mellifera – Implications for artificial insemination of bumble bees
Campion, Claire; Rajamohan, Arun; Rinehart, Joseph P. Abstract This study evaluates the efficacy of a cryopreservation protocol for spermatozoa derived from the accessory testis of male Bombus impatiens. It is also the first report of successful cryopreservation of bumble bee spermatozoa. The spermatozoa viability was compared with the similarly treated honey bee spermatozoa derived from…
Anoxia hormesis improves performance and longevity at the expense of fitness in a classic life history trade-off.
De La Torre, Alyssa; López-Martínez, Giancarlo 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…
