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.

The importance of tree allometry for local-scale variation in aboveground biomass [PDF]
, 2018 Aboveground biomass (AGB) plays a critical role in determining the long-term dynamics of carbon in tropical forests. Consequently, understanding what factors are important in controlling AGB in tropical forests has major implications for projecting the ...

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 ...

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders
Integrative Zoology, EarlyView.We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions
Integrative Zoology, EarlyView.Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Height-diameter allometry of tropical forest trees
, 2011 Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent H and D measurements encompassing 283 sites in 22 ...

Biomass Allometries for Urban Trees: A Case Study in Athens, Greece
ForestsUrban street trees often exhibit distinct architectural characteristics compared to their counterparts in natural forests. Allometric equations for the stem (MS), branches (MB), and total dry aboveground biomass of urban trees (MT) were developed, based on 52 destructively sampled specimens, belonging to 10 different species, growing in the ...

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats
Integrative Zoology, EarlyView.Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Inferring processes within dynamic forest models using hybrid modelling
Methods in Ecology and Evolution, EarlyView.Abstract Modelling forest dynamics under novel climatic conditions requires a careful balance between process‐based understanding and empirical flexibility. Dynamic vegetation models (DVM) represent ecological processes mechanistically, but their performance is sensitive to misspecified functional forms and to unavoidable structural simplifications ...
