Proteomic differences in seminal fluid of social insects whose sperm differ in heat tolerance
Royal Society Open Science, 2023 In the coming years, climate change is likely to increase the frequency and intensity of heatwaves. In many organisms, heat stress provokes physiological perturbations and can lead to decreased male fertility.

The large carpenter bee Xylocopa augusti (Hymenoptera: Apidae): new record for Chile [PDF]
, 2013 The large carpenter bee Xylocopa (Neoxylocopa) augusti Lepeletier de Saint Fargeau, 1841, is here recorded for the first time in Chile. This new record increases to four the number of carpenter bees known for the country.

Measurement of electric charges on foraging bumblebees (Bombus terrestris) [PDF]
Journal of Physics: Conference Series, 2019 Abstract Bumblebees carry electric charge. Almost always positive, this charge facilitates pollen transfer between bumblebee and flower during pollination and is likely to play a role in the detection of electric fields. Models of the Coulomb forces acting on pollen grains during pollination are predominantly based upon laboratory ...

Colony and individual life-history responses to temperature in a social insect pollinator [PDF]
, 2015 Pollinating insects are of major ecological and commercial importance, yet they may be facing ecological disruption from a changing climate. Despite this threat, few studies have investigated the life-history responses of pollinators to experimentally ...

A failed invasion? Commercially introduced pollinators in Southern France [PDF]
, 2009 The natural diversity of Bombus terrestris subspecies could be under threat from the commercialisation of bumblebees. Therefore, to determine whether commercially imported bumblebees are able to establish and spread, we carried out

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,
