Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Ten Bee Species New to Green Roofs in the Chicago Area [PDF]

open access: yes, 2018
Green roofs increasingly provide habitat for many insects in urban environments. Pollinators such as bees may utilize foraging and nesting resources provided by green roofs but few studies have documented which species occur in these novel habitats. This

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.

Fruitgrowers towards a new approach to enhance biodiversity in organic orchards [PDF]

open access: yes, 2008
In the frame of the project “Arbeitsnetz zur Weiterentwicklung der Anbauverfahren des ökologischen Obstbaus” (BOEL-project Nr. 03OE178) a group of fruitgrowers and advicers started to discuss new measures and new concepts to enhance biodiversity in ...

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.

Ecosystem services of biodiversity in organic grasslands [PDF]

open access: yes, 2011
The use of multi-species mixtures in herbage production can add value in terms of improved conditions for pollinating insects, better resource utilization, carbon sequestration, yield stability, animal health and product quality.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

open access: yesIntegrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Genomic insights into neonicotinoid sensitivity in the solitary bee Osmia bicornis.

open access: yesPLoS Genetics, 2019
The impact of pesticides on the health of bee pollinators is determined in part by the capacity of bee detoxification systems to convert these compounds to less toxic forms.

Draft Genome Assembly and Population Genetics of an Agricultural Pollinator, the Solitary Alkali Bee (Halictidae: Nomia melanderi)

open access: yesG3: Genes, Genomes, Genetics, 2019
Alkali bees (Nomia melanderi) are solitary relatives of the halictine bees, which have become an important model for the evolution of social behavior, but for which few solitary comparisons exist.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.
