Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

open access: yesActa Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Toxicokinetic modelling of the synthetic cannabinoid 5F‐MDMB‐P7AICA and its main metabolite in pigs following pulmonary administration

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Since their emergence on the drug market, synthetic cannabinoids (SC) are still gaining increasing importance in forensic toxicology. The representatives of the so‐called new psychoactive substances have in common that they have not undergone preclinical safety studies. Hence, knowledge on toxicokinetic (TK) data is sparse.

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

open access: yesCladistics, 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

Integrating Indigenous knowledge and modern statistical approaches to model wildlife density based on animal track counts

open access: yesConservation Biology, EarlyView.
Abstract In multiuse areas outside formal protection, sustaining both wildlife and people is critical to wildlife conservation and coexistence efforts. Botswana's Kalahari hosts one of sub‐Saharan Africa’s largest unprotected areas supporting free‐ranging wildlife.

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

open access: yesDiabetes, 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 ...

Nutritional Stress Modulates Developmental Thresholds in a Male Dimorphic Mite

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Global warming can alter nutrition during development, but whether this affects phenotype expression solely through changes in condition or also through developmental decision‐making remains unclear. In the male‐dimorphic bulb mite Rhizoglyphus robini, nutritional stress shifted the developmental threshold for fighter versus scrambler expression and ...

An AI‐Driven Biomass Estimation Tool Enabling Population‐ and Specimen‐Level Variation Analyses: A Case Study on Parasitoid Flies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We present the first ecological application of InsectMorphoAI, a tool estimating curvilinear body length and body volume from two‐dimensional fly images. Applying this approach to tachinid flies from a Mediterranean forest near Rome, Italy, we quantified species composition, abundance, body size, body proportions, and biomass proxies in assemblages ...

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

open access: yesJournal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Navigating morphometric minefields: Modelling heteroscedasticity in length‐conversion models

open access: yesJournal of Fish Biology, EarlyView.
Abstract A common problem when combining data on species' traits from multiple sources is that researchers often measure the same trait in different ways. For example, the length of a shark can be measured in a straight‐line or over‐the‐body, and for lengths that include the tail (e.g., fork and total lengths), with the tail in ‘stretched’ or ‘natural’
