Enhanced fish detection sensitivity in aquatic systems using environmental RNA

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

Animal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...

Hair Degradation Patterns in Aquatic and Soil Environments

Archaeometry, EarlyView.
ABSTRACT Hair is a biological material that can provide information in archaeology and forensics. Previous studies have mainly examined changes occurring post‐mortem. In this study, we focused on hair pulled out ante‐mortem. The aim of the study was to identify patterns in the degradation of hair in water and soil.

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Contributions to the Knowledge of the Larval Morphology of Synalpheus Spence Bate, 1888 (Caridea: Alpheidae): Description of the First Zoea of S. antillensis Coutière, 1909 and S. cf. townsendi Coutière, 1909 Reared in Laboratory

Acta Zoologica, EarlyView.
ABSTRACT The first zoea of two Synalpheus species, namely: S. antillensis and S. cf. townsendi, are herein described. They were also compared with the genus descriptions and with their respective species complexes available in the literature. Morphological information on Synalpheus zoea I exhibits an increase from 19 to 21 species, and it corresponds ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.
