Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

open access: yesEcological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Why we Should Study Solitary Species to Understand the Costs of Group‐Living

open access: yesEthology, EarlyView.
It's easier to measure the benefits than the costs of a trait. Solitary species benefit by avoiding the costs of group living. Thus, measuring benefits of solitary living informs us about the costs of group living. ABSTRACT While for decades behavioral ecologists have studied the benefits of group living, measuring its costs has been more difficult. It

Leaders Are Somethin' Else: Behavioural Variation Associated With Roles During Tandem Running Recruitment

open access: yesEthology, EarlyView.
In this study, we found moderate to strong repeatabilities in behavioural variables measuring the personality traits: activity, aggressiveness and exploration. Similarly, the probability of acting as a leader during tandem running in an emigration event was moderately (R = 0.469) repeatable.

Syntactic awareness as a mediator of reading–writing relations in young Chinese L2 learners

open access: yesForeign Language Annals, EarlyView.
Abstract This longitudinal study examined the mediating role of syntactic awareness in reading–writing relations among young learners of Chinese as a second language (L2). A total of 177 students from non‐Chinese‐speaking backgrounds in Hong Kong were assessed annually from Grades 4 to 6 on word‐level literacy (character reading, spelling), sentence ...
