Insect Science, EarlyView.Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Current Biology, 2018 Parental care is costly for animal parents [1-3], who often desert, abort, or kill their offspring and sometimes even eat them-so-called filial cannibalism [1, 4].

It's Complicated: How Sex, Family, and Season Affect Growth of a Sexually Size Dimorphic Spider
Integrative Zoology, EarlyView.Extreme female‐biased sexual size dimorphism (SSD) in Nephilingis cruentata emerges when male and female growth trajectories diverge mid‐development. Seasonal effects influence both sexes similarly, but family effects are strongly sex‐specific. These patterns identify a critical developmental window for mechanistic studies of SSD.

The superposition method for the reconstruction of food webs
Methods in Ecology and Evolution, EarlyView.Abstract Understanding trophic positions is essential for analysing complex food webs. While calculating these positions can be straightforward when feeding relationships and their proportions are known, determining diet coefficients traditionally requires substantial time and effort.

Animal Conservation, EarlyView.Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Acta Agriculturae Slovenica, 2009 Paper presents a larval cannibalism of green lacewings (Chrysoperla carnea), which was observed during the laboratory bioassay on non-target effect of entomopathogenic nematodes against green lacewings larvae.

The Mutable Original: How Chinese Counterfeits Become Nigerian Originals in African Markets
American Anthropologist, EarlyView.ABSTRACT Affordable Chinese copies of Western brands are ubiquitous in African markets. Despite democratizing consumer access, these goods appear to cement hegemonic value hierarchies that rank Chinese or local products as inferior to Western goods.
