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

Ecological 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 ...

Diversity of the Nests of Social Wasps (Hymenoptera: Vespidae: Polistinae) in the Northern Pantanal, Brazil

Sociobiology, 2014
Some species of wasps demonstrate plasticity with diverse nesting habits according to the environmental conditions and substrates used for building the nests, while others are restricted to habitats with specific conditions and may exhibit some degree ...

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

Ecological 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

European 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 ...

Imidacloprid Alters Activity and Responses to a Visual Predator Stimulus in Aussie Bronze Jumping Spiders (Helpis minitabunda, Araneae, Salticidae)

Ethology, EarlyView.
A field‐recommended concentration of a commercial imidacloprid formulation reduced open arena activity and slowed climbing in the jumping spider Helpis minitabunda. Exposed spiders still detected a looming predator stimulus, but their responses were reduced.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries 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.
