Solitary bee abundance and species richness in dynamic agricultural landscapes

, 2013
Remerciements : F. Le Moal, R. YantierInternational audienceWe investigated the influence of the landscape structure on solitary bee abundance and species richness in an agricultural area of western France. We focused on the role of semi-natural habitats,

Effects of heat shocks, heat waves, and sustained warming on solitary bees

Frontiers in Bee Science
Along with higher average temperatures, global climate change is expected to lead to more frequent and intense extreme heat events, and these different types of warming are likely to differ in their effects on bees. Although solitary bees comprise >75%

Diets maintained in a changing world: Does land‐use intensification alter wild bee communities by selecting for flexible generalists?

Ecology and Evolution, 2022
Biodiversity loss, as often found in intensively managed agricultural landscapes, correlates with reduced ecosystem functioning, for example, pollination by insects, and with altered plant composition, diversity, and abundance.

The ecology of solitary bees

Hilgardia, 1958
Bees play an important and necessary role in the pollination of agricultural crops grown for fruit and seed and of forage and browse plants important in range management for production of both livestock and game animals. Nearly 20,000 different kinds of bees are now known, some, like the imported honey bee, the bumble bees ...

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

Journal 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.

Linking pollen foraging of megachilid bees to their nest bacterial microbiota

Ecology and Evolution, 2019
Solitary bees build their nests by modifying the interior of natural cavities, and they provision them with food by importing collected pollen. As a result, the microbiota of the solitary bee nests may be highly dependent on introduced materials.

Description and validation of an improved method to feed solitary bees (Osmia spp.) known amounts of pesticides

Ecotoxicology and Environmental Safety, 2023
Pesticide exposure is an important driver of bee declines. Laboratory toxicity tests provide baseline information on the potential effects of pesticides on bees, but current risk assessment schemes rely on one species, the highly social honey bee, Apis ...

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

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

Economic 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.

Solitary bee larvae modify microbial diversity of pollen provisions in the stem-nesting bee, Osmia cornifrons (Megachilidae)

, 2022
In this study, we set out to explore how solitary bee larvae impact the brood cell microbiome in a common, easily manipulated, solitary, stem-nesting bee, Osmia cornifrons (Megachilidae).
