Harnessing community science to conserve and study ground-nesting bee aggregations

open access: yesFrontiers in Ecology and Evolution
Protecting diverse solitary ground-nesting bees remains a pivotal conservation concern. Ground-nesting bees are negatively impacted by anthropogenic land use change that often removes suitable nesting habitat from the landscape.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Laboratory acute contact toxicity test with the leafcutter bee Megachile rotundata

open access: yesJulius-Kühn-Archiv, 2020
So far little is known about the toxicity of Plant Protection Products (PPPs) to solitary bees other than Osmia spp. as well as the inter- and intra-species sensitivity differences of honey bees and solitary bees.

Morphology and temporal evolution of ground-nesting bee burrows created by solitary and social species quantified through X-ray imaging

open access: yesGeoderma, 2023
Most research on wild bees has focused on their role as pollinators, while their importance as soil ecosystem engineers has been largely overlooked, despite the fact that most species nest in the soil.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Linking pollen foraging of megachilid bees to their nest bacterial microbiota

open access: yesEcology 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.

Rising Strong: Cultivating Resilience in Edible City Entrepreneurship. Insights Into the Landscape of Urban Food Initiatives

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In response to growing global challenges, this study explores how social entrepreneurship within the Edible City movement contributes to building resilient, sustainable, and equitable urban food systems. Drawing on semistructured interviews with over 70 stakeholders across five cities—Berlin, Andernach, Oslo, Rotterdam, and Havana—we ...

Solitary Bees Facing Climate Change

open access: yesSociobiology
Solitary bees comprise over 15,000 species. They represent the vast majority of bees on earth (>77%), but they are less studied than the social species.

Succession influences wild bees in a temperate forest landscape: the value of early successional stages in naturally regenerated and planted forests. [PDF]

open access: yesPLoS ONE, 2013
In many temperate terrestrial forest ecosystems, both natural human disturbances drive the reestablishment of forests. Succession in plant communities, in addition to reforestation following the creation of open sites through harvesting or natural ...
