Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

open access: yesJournal of Fish Biology, EarlyView.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

open access: yesJournal of Anatomy, EarlyView.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Bad Practices: Unintended Consequences of Practice‐Based Theories of Reference

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT Practice theories are a genus of causal theories of reference. They claim that the semantic referent of an utterance of a name is determined by features of a practice of using that name to speaker‐refer to, or coordinate actions around, a certain object.

Digital Disease Ecologies: Encounter, Datafication and the Digital Geographies of One Health

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract Through the case of Snake Awareness Rescue Protection App (SARPA), a digital snake translocation and snakebite prevention mobile phone application in Kerala, India, this paper extends recent geographical ‘digital ecologies’ scholarship's concern for the digitisation of more‐than‐human worlds to digital health technology and disease ...

Jungle Cats and Leopard Cats: Distribution, Occupancy Modeling, and Activity Patterns in Bardia National Park, Nepal

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Camera trap captured photographs from the study area, on the left is the jungle cat, and on the right is the leopard cat. ABSTRACT Small cats play a vital role in maintaining ecological balances. Inadequate knowledge based on their habitat preference and interspecific competition has hindered the effective conservation initiatives. We studied occupancy

Phenotypic Plasticity Across Gradients of Predation and Competition in Larval Amphibians

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Many taxa encounter a wide range of conditions for any particular environmental variable and they experience variation in multiple environmental variables simultaneously, which may have interactive effects if different environmental types induce opposing phenotypes.

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 238-258, April 2026.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Assessment of High Throughput Sequencing Quality of Host DNA Enriched From Faeces: A Case From Captive Tiger

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Faeces serve as a widely used non‐invasive material in wildlife studies, from which host DNA can be enriched for high‐throughput sequencing. However, the characteristics of faecal DNA sequencing, particularly the relationship between sequencing volume and genotyping accuracy or genomic coverage, have remained unclear.
