Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

Ecography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Wolves and humans both shape patterns of deer browsing in a temperate forest ecosystem of Central Europe

Ecography, EarlyView.
Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.

Everything Changed, Yet Hunting Rights Did Not: Formulation of Wildlife Property Rights in Postsocialist Slovenia

Environmental Policy and Governance, EarlyView.
ABSTRACT This study uses the policy regime framework to examine how background conditions, institutions, and actor configurations shaped hunting rights within the forest–wildlife policy domain during Slovenia's postsocialist transformation. Drawing on media analysis, in‐depth interviews with policymakers, and legislative documents, it conducts a ...

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

Epilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early

Microvascular Abnormalities in Adolescents With Anorexia Nervosa: Nailfold Video Capillaroscopic Evidence at Acute and Remission States

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Chronic malnutrition, hypothermia, and hormonal imbalance in anorexia nervosa (AN) may impair capillary structure and perfusion. This study aimed to describe the nailfold videocapillaroscopy (NVC) findings in adolescents with AN and atypical AN (AAN), to assess their association with Raynaud's phenomenon (RP), and evaluate ...
