Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Regional and local divergence in welfare provision in England and Wales, 1776–1815

open access: yesThe Economic History Review, EarlyView.
Abstract This article uses the township‐level data on welfare expenditure and provision gathered by parish officers in England and Wales at three points between 1776 and 1815 to illuminate regional and local differences during the period. These data have been linked to geographic information system (GIS) mapping systems, facilitating the mapping of ...

Floral resource availability and surrounding land cover influence bumble bee community composition in an agricultural landscape

open access: yesInsect Conservation and Diversity, EarlyView.
Multispecies occupancy models indicated that the occurrence of bumble bees was associated with local floral resources as well as the landscape surrounding a site within 1.6 km. Estimated species richness was greater at sites with more forest cover and lower at sites with more corn and soybean agriculture in the surrounding landscape.

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

open access: yesInsect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Pathway to Non‐Normative Political Engagement: The Role of Psychological Reactance in Episodic Memories During the COVID‐19 Pandemic

open access: yesJournal of Applied Social Psychology, EarlyView.
ABSTRACT Dissatisfaction with Institutions, governments, or the status quo can be expressed via normative (e.g., sign a petition) and non‐normative (e.g., destroy public property) political engagement. The type of political engagement endorsed may be influenced by memories rooted in psychological reactance, as chronic memory activation is known to ...

Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.
