Designer benzodiazepines (DBZDs) are a class of new psychoactive substances (NPS) designed as legal alternatives to prescription BZDs. Bromazolam has been the most prevalent DBZD detected on the recreational market around the world; however, a new DBZD, ethylbromazolam (8-bromo-1-ethyl-6-phenyl-4 H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine; also known as bromoethylazolam) has recently emerged. In this study, the emergence of e...

The Malabar red snapper ( Lutjanus malabaricus ) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic contributions. A clear understanding of gonadal sex differentiation is essential for designin...

Large‐scale double‐digest RAD sequencing (ddRADseq) datasets generated for genotyping are increasingly available in aquaculture, yet their unmapped reads remain largely unexplored for pathogen surveillance. Here, we evaluated the utility and limitations of repurposing unmapped ddRADseq reads to examine pathogen‐associated and disease‐associated microbiome‐pathobiome patterns during scale drop disease (SDD) outbreaks in farmed...

Because young-of-year (YOY; age-0) are vulnerable to overwinter mortality, fishes invading higher latitudes could encounter colder conditions that impose population bottlenecks, but warming under climate change could reduce such restrictions. To examine how populations might respond to anticipated warming and whether they could establish, we developed a life-history model, integrating four published empirical relationships (da...

Biogenic structural complexity is a key driver of biodiversity and ecosystem functioning, yet its ecological and environmental determinants remain poorly understood across broad biogeographic scales. Here, we conducted standardized 90‐day field experiments at 16 coastal sites, spanning a 41‐degree latitudinal gradient, using naturally assembled marine fouling communities on settlement panels. We measured rugosity as our metric...

Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...

Quantifying animal movements is necessary for answering a wide array of research questions in ecology and conservation biology. Consequently, ecologists have made considerable efforts to identify the best way to estimate an animal's home range, and many methods of estimating home ranges have arisen over the past half a century. Most of these methods fall into two distinct categories of estimators that have only recently been d...
