PLoS ONE, 2018 Gut microbial communities are critical for the health of many insect species. However, little is known about how gut microbial communities respond to anthropogenic changes and how such changes affect host-pathogen interactions.

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany
Insect Conservation and Diversity, EarlyView.Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

Bee community and trait‐based responses to fire in a Mediterranean landscape
Insect Conservation and Diversity, EarlyView.Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Microsatellite-Based Genetic Analysis of a Wild Alpine Bumblebee and the Environmental Drivers of Its Genetic Diversity. [PDF]
Ecol EvolHigh genetic diversity was detected in 539 B. kashmirensis individuals from 36 populations in Qinghai Province using 15 SSR markers. STRUCTURE, UPGMA, and PCoA analyses revealed east–west genetic clustering of populations. Environmental factors such as latitude, longitude, solar radiation, and vapor pressure influence genetic diversity. ABSTRACT Bombus

Estimating wild bee population size with validated distance sampling
Insect Conservation and Diversity, EarlyView.Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

Extinctions of aculeate pollinators in Britain and the role of large-scale agricultural changes [PDF]
, 2014 Pollinators are fundamental to maintaining both biodiversity and agricultural productivity, but habitat destruction, loss of flower resources, and increased use of pesticides are causing declines in their abundance and diversity. Using historical records

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops
Journal of Applied Entomology, EarlyView.ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...
