STbayes: An R package for creating, fitting and understanding Bayesian models of social transmission
Methods in Ecology and Evolution, EarlyView.Abstract A critical consequence of joining social groups is the possibility of social transmission of information related to novel behaviours or resources. Network‐based diffusion analysis (NBDA) has emerged as a leading frequentist framework for inferring and quantifying social transmission, particularly in non‐human animal populations.

AgricultureThe ectoparasitic mite Varroa destructor is well known for transmitting a number of viruses that can contribute to the collapse of honeybee colonies. To date, the many control measures put in place to limit the spread of V.

A general method for detection and segmentation of terrestrial arthropods in images
Methods in Ecology and Evolution, EarlyView.Abstract Automated monitoring of insects and other arthropods is vital for ecological research and conservation; yet current image recognition tools often lack generalizability across diverse imaging conditions and struggle with varying specimen sizes. This limits their practical utility and wide adoption by ecologists.

Integration of epigenetics into ecotoxicology: insights and fundamental research needs
Biological Reviews, EarlyView.ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations [PDF]
, 2012 Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences.

Contact Dermatitis, EarlyView.Propolis is rarely used in conventional cosmetics within the EU, and such products are therefore unlikely to be significant sources of exposure for patients with positive patch test reactions to propolis. There is no evidence that small amounts of propolis in white beeswax (cera alba) in cosmetics can trigger allergic contact dermatitis in individuals ...

Conservation Science and Practice, EarlyView.Abstract Biodiversity corridors aim to reconnect fragmented habitats and protected areas, yet their impact on landowners varies and requires assessment. In the Central Annamite Landscape, Vietnam, initiatives like Payment for Forest Environment Services (PFES) for watershed protection, forest restoration, and non‐timber forest product development ...

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction
Entomologia Experimentalis et Applicata, EarlyView.Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.
