Unbiased RNA shotgun metagenomics in social and solitary wild bees detects associations with eukaryote parasites and new viruses [PDF]

open access: yes, 2016
The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere of the western honey bee, Apis mellifera.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

The Savage Worlds of Henry Drummond (1851–1897): Science, Racism and Religion in the Work of a Popular Evolutionist

open access: yesJournal of Religious History, EarlyView.
Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

Proventricular structure in solitary bees (Hymenoptera: Apoidea) [PDF]

open access: yesOrganisms Diversity & Evolution, 2005
AbstractProventricular structure, analyzed by scanning electronic microscopy, is compared among 28 species of solitary bees representing four families. Observations on the shapes of proventricular folds and on hair-like cuticular projections are presented, discussed, and suggested as useful to future studies of bee systematics.

Does Decreasing the Generosity of Payments to Single Parents Have Employment and Earnings Effects? Evidence from Australian Administrative Data*

open access: yesEconomic Record, EarlyView.
We examine the impact of two changes to Australia's Parenting Payment Single (PPS) program, a welfare payment for low‐income single mothers. One change lowered the age of the youngest child cut off for program eligibility, forcing new welfare entrants onto the less generous Newstart (unemployment) payment.

Are landscape structures insurmountable barriers for foraging bees? A mark-recapture study with two solitary pollen specialist species [PDF]

open access: yes, 2018
To investigate whether landscape structures act as insurmountable barriers for foraging bees, we conducted mark-recapture studies with two pollen-specialist solitary species.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.
