Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

Ecological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Flower Constancy of Bumblebees – The Case of Onobrychis pindicola (Fabaceae) Pollinators

Journal of Apicultural Science, 2018
Pollination in high mountain habitats is an important ecosystem service in climate change conditions. The aim of this study was to use pollen load analysis to assess flower constancy and foraging choices of bumblebees foraging on Onobrychis pindicola, a ...

Understanding the Flight of the Bumblebee

PLoS Biology, 2012
Bumblebees are remarkable navigators. While their flight paths may look scattered to the casual eye, all that buzzing about is anything but random. Like the travelling salesman in the famous mathematical problem of how to take the shortest path along multiple stops, bumblebees quickly find efficient routes among flowers. And once they find a good route,

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

Ibis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

Spatial Reorientation by Geometry in Bumblebees

PLoS ONE, 2012
Human and non-human animals are capable of using basic geometric information to reorient in an environment. Geometric information includes metric properties associated with spatial surfaces (e.g., short vs. long wall) and left-right directionality or 'sense' (e.g. a long wall to the left of a short wall).

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Canadian boreal restored mining sites sustain diverse pollinator communities, including species of conservation concern

Insect Conservation and Diversity, EarlyView.
Revegetated mine tailing storage facilities support pollinator abundance, diversity, richness and evenness comparable to recently logged boreal forest sites. Agronomic and spontaneous revegetation strategies host similar pollinator and Bombus community structures, indicating multiple rehabilitation approaches can effectively restore pollinator habitat.

Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

Insect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

Memory Matters: Bumblebee Behavioral Models for Vehicle-to-Vehicle Communications

IEEE Access, 2018
Vehicles forming connected communication networks are routinely challenged with the complex decision problem of either staying with the same wireless channel or moving to a different wireless channel when experiencing highly variable channel quality ...
