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.

Decision-Feedback Equalisation Using Multiple-Hyperplane Partitioning for Detecting ISI-Corrupted $M$-ary PAM Signals

, 2001
A novel decision feedback equaliser (DFE) scheme is derived based on multiple-hyperplane partitioning of signal space for detecting $M$-ary PAM symbols transmitted through an intersymbol interference (ISI) and noisy channel.

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 ...

Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

Methods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

American Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Phylogenetic and ecological duality in the otoliths of Sciaenidae

Cladistics, EarlyView.
Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).

Sex‐Stratified Associations of DXA‐Derived Adiposity, Regional Fat Distribution and Muscle Power With Incident Hospitalised Cardiovascular Disease in Older Adults: A Prospective Cohort Study

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims To investigate the sex‐stratified associations of DXA‐derived adiposity, regional fat distribution and muscle power with incident hospitalised cardiovascular disease (CVD) in older Chinese adults. Materials and Methods This prospective cohort included 3168 community‐dwelling older adults (1548 men and 1620 women; median age 72.0 years ...

Size‐, sex‐ and site‐dependent morphological variation in the stone flounder (Kareius bicoloratus) from Korean coastal waters

Journal of Fish Biology, EarlyView.
Abstract Kareius bicoloratus is a commercially important flatfish in Korean coastal fisheries and an ecologically relevant benthic species in nearshore ecosystems. To evaluate how multiple biological and environmental factors jointly shape flatfish morphology, we analysed 81 morphometric indices and two‐dimensional geometric morphometrics (GMM) in wild

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

Journal of Fish Biology, EarlyView.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...
