Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

open access: yesEcological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

Canopy position and tree size structure the distribution of honeydew‐producing scale insects (Hemiptera: Coccoidea) in a temperate hardwood forest

open access: yesEcological Entomology, EarlyView.
Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.

Eosinophilia and Hypereosinophilia: A Practical Approach to Navigating a Broad Differential Diagnosis

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Eosinophilia, defined as an absolute eosinophil count (AEC) of ≥ 0.5 × 109/L, is a frequently encountered finding with a vast spectrum of potential underlying etiologies. Hypereosinophilia (HE) is defined as AEC > 1.5 × 109/L and may become life‐threatening when eosinophil‐induced organ damage occurs, defining the hypereosinophilic syndrome ...

Corpses as Repositories of Information and Funerals as Information Centres: Why Natural Selection Favours the Bereaved

open access: yesEthology, EarlyView.
Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.
