The evolutionary ecology of sibling cannibalism in the wild
Sibling cannibalism is common amongst animals. Whilst the role relatedness plays in this behaviour has been well studied due to the strong ties between cannibalism and evolutionary theory, we lack enough knowledge of the ecology underlying this behaviour

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.

Community-Level Consequences of Cannibalism
, 2012 Ecological interactions determine the structure and dynamics of communities and their responses to the environment. Understanding the community-level effects of ecological interactions, such as intra- and interspecifc competition, predation, and ...

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.

Cell Cannibalism in Oral Precancerous Lesions and Squamous Cell Carcinoma [PDF]
Iranian Journal of OtorhinolaryngologyIntroduction:Cellular cannibalism is defined as a process of non-apoptotic cell death. This phenomenon has been indicated to be associated with aggressiveness, anaplasia, invasiveness, and metastatic potential of various malignancies.

Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider
Integrative Zoology, EarlyView.We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

Integrative Zoology, EarlyView.Typhlomys daloushanensis, a poorly known and unique echolocating rodent. Using a captive breeding colony, we quantify key reproductive parameters, including gestation length, litter size, interbirth interval, and development to maturity, and evaluate these in relation to mating system structure.

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 ...
