Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Relationships between human tibia diaphysis shape and experimental injury outcomes

Journal of Forensic Sciences, EarlyView.
Abstract Interpretation is central to skeletal trauma analysis; however, the influence of intrinsic skeletal variation, such as long bone shape, on injury is not fully understood. While previous studies have emphasized extrinsic variables such as loading rate, direction, and number of impacts, this study investigates whether diaphyseal shape variation ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

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.

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

Integrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...
