How closed is “closed”? Ambiguity in British Columbia’s Closed Containment aquaculture regulations
Published: 2026-08-14
Subjects: Animal Sciences, Aquaculture and Fisheries Life Sciences, Life Sciences, Zoology
We examine disease-transmission risks to wild salmon associated with containment technologies proposed in 2025 under British Columbia’s transition away from open-net pen aquaculture. To ensure consistent terminology, and to avoid the mischaracterization of marine “semi-closed” flow-through systems as “closed containment,” we clarify categories of aquaculture production technologies and compare [...]
Beyond participation: Indigenous researchers leading biodiversity monitoring and territorial governance in the Amazon
Published: 2026-08-14
Subjects: Biodiversity, Integrative Biology
Indigenous Territories harbor some of the world’s best-preserved ecosystems and are central to biodiversity conservation. Paradoxically, the knowledge of the people who have historically maintained these ecosystems remains underrepresented in conservation science. Here we present a collaborative program for monitoring biodiversity and water quality of the Nãnsêpôtiti (Iriri) River in the Panará [...]
Using large language models to identify reporting challenges for Target 6 implementation: a short validation against human assessment
Published: 2026-08-14
Subjects: Artificial Intelligence and Robotics, Biodiversity, Research Methods in Life Sciences
National reports and related biodiversity policy documents contain important information on implementation barriers, but extracting comparable evidence across many countries is timeconsuming. We tested whether large language models (LLMs) could provide a reliable firstpass synthesis of reported challenges relevant to Target 6 of the Kunming–Montreal Global Biodiversity Framework. Human assessor [...]
Plant sex chromosome evolution in the phylogenomic era
Published: 2026-08-14
Subjects: Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Life Sciences, Plant Sciences
Plants harbor a tremendous diversity of sexual systems, including various forms of chromosomal sex determination that have arisen repeatedly across major clades, especially in angiosperms. The causes and consequences of sex chromosome evolution are far-reaching, with implications for sexual system, mating system, and life history evolution, genome architecture, and speciation, extinction, and [...]
Reproduction is more sensitive to warming than adult lifespan across invertebrates
Published: 2026-08-11
Subjects: Animal Sciences, Biodiversity, Entomology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
Studies estimating the effect of temperature on wild animal populations typically focus on survival as a proxy for population health. However, high and low temperatures can also negatively influence animal reproduction, and recent work suggests that the thermal sensitivity of reproduction is more important for population persistence that the thermal sensitivity of survival in some species groups. [...]
The life cycle of the tapeworm Dibothriocephalus latus in Switzerland: what we know, what we miss, and how it is sustained
Published: 2026-08-11
Subjects: Life Sciences
Dibothriocephalus latus is a broad fish tapeworm with a complex life cycle that requires three host stages - copepods, fish, and humans. Over the last 25 years, the prevalence of D. latus has noticeably declined in many parts of Europe, with the exception of the Alpine region. Recent studies have shown that D. latus is prevalent in fish from sub-alpine lakes, the second intermediate host, which [...]
Revisiting Taylor's law, rediscovering Smith's law: A dual framework for scaling heterogeneity
Published: 2026-08-11
Subjects: Life Sciences, Physical Sciences and Mathematics
Taylor's (1961) power law (TPL)—variance scales with mean density—originated in agricultural entomology but now spans the natural and social sciences and even the humanities. Cited over 8,000 times and featured in Nature for decades, its reach far exceeds its ecological origins. Yet TPL has been dormant in Nature for the past two decades, though it remains active in PNAS. Smith's (1938) law [...]
Lake Champlain fisheries and ecosystem in the context of the Laurentian Great Lakes: past research, current management issues, and future research priorities
Published: 2026-08-11
Subjects: Ecology and Evolutionary Biology, Life Sciences
Lake Champlain is a large lake bordered by New York, Vermont, and Quebec. This bi-national, multi-jurisdictional lake shares many management issues and challenges with the much larger bi-national Laurentian Great Lakes, including a history of commercial fisheries, species declines and extirpations, sport fisheries supported by stocking, and invasion of non-native species. The bathymetric [...]
Integrating primary and meta-analytic effect size estimates on the effects of PFAS and organochlorine pesticides on human health outcomes
Published: 2026-08-11
Subjects: Medicine and Health Sciences
Persistent organic pollutants such as per- and polyfluoroalkyl substances (PFAS) and organochlorine pesticides are among the most extensively studied environmental contaminants, yet the evidence base remains fragmented across primary studies and meta-analyses, limiting its ability to chart new research directions. To address this fragmentation, we developed a unified database that links primary [...]
Ecological Patterns in Mammalian Vocal Frequencies: Evidence Across Body Sizes and Habitats
Published: 2026-08-11
Subjects: Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Vocalisations in mammals are an important sensory modality that is used for various purposes in communication, courtship, territorial display, navigation, prey detection, predator avoidance, reproduction, and social coordination. These various call functions are differentiated from each other through certain properties. Call spectral properties are influenced by anatomical constraints, especially [...]
Chromosomal speciation through holocentric lenses
Published: 2026-08-11
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Chromosomal rearrangements (CRs) can trigger speciation by acting as barriers to gene flow. Two main theoretical frameworks were developed on how they contribute to speciation: causing infertility in heterokaryotypes (hybrid dysfunction) or creating islands of divergence through recombination suppression. However, these theories were developed with monocentric chromosomes in mind. Species with [...]
Assessing phylogenetic inference in the era of AI-driven protein structures
Published: 2026-08-11
Subjects: Bioinformatics
Phylogenetic inference is one of the most common downstream applications of multiple sequence alignment. Quantitative assessment of inferred trees is essential for evaluating the reliability of both alignments and phylogenetic inferences. Establishing a robust assessment framework for phylogenetic trees therefore provides a basis for examining and improving methods for alignment and tree [...]
Beyond the mammalian nucleolus—a comparative perspective on nucleolar dynamics in stress and through the life cycle
Published: 2026-08-11
Subjects: Cell and Developmental Biology, Cell Biology, Ecology and Evolutionary Biology, Evolution, Microbiology, Organismal Biological Physiology
Classically the site of ribosomal RNA transcription, processing and early ribosome assembly, the nucleolus is increasingly understood as a dynamic multiphase condensate reshaped by cell state. Most reviews of this plasticity are mammal-centred. Here we set mammals alongside fungi, plants and animal germlines, following the nucleolus through the life cycle under environmental change and through [...]
Impacts of the end Pliocene marine megafaunal extinction on North Atlantic trophic structure
Published: 2026-08-11
Subjects: Ecology and Evolutionary Biology
Marine megafauna are experiencing widespread population declines and these losses are expected to have cascading effects, impacting ecosystem structure and function. However, quantifying these ecological consequences at a global scale remains challenging, requiring an understanding of long-term trophic dynamics. Palaeoecology can provide useful insights into how communities respond to taxonomic [...]
Are mixed forests more resilient to a warmer and drier climate? A review on adaptive forest management of beech-oak forests in Europe
Published: 2026-08-07
Subjects: Forest Management
European forests are increasingly threatened by climatic extremes such as hot droughts, which impair their vitality and ecosystem services provision. Mixing tree species with contrasting functional traits and resource use, such as beech (Fagus sylvatica L.) and oaks (Quercus petraea (Matt.) Liebl., Quercus robur L., and Quercus pubescens Willd.) may enhance forest resilience and decrease [...]
