Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

open access: yesAnimal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Minocycline and bone marrow–derived mononuclear cells as potential therapeutics for hereditary retinal degenerations

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To assess in Royal College of Surgeons (RCS) rats if the combination of two previously documented neuroprotective strategies: minocycline administration and bone marrow–derived mononuclear cells (BM‐MNCs) intravitreal transplantation, offers enhanced neuroprotection compared with each treatment alone.

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, EarlyView.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
