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 [...]
Impact of warming on functional traits of a keystone grazer in Arctic lakes
Published: 2026-08-07
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Laboratory and Basic Science Research Life Sciences, Terrestrial and Aquatic Ecology
Temperature rise is one of the most pronounced abiotic changes currently affecting Αrctic ecosystems. Knowledge about the adaptation capacity of their key species is urgently needed to better understand the ecological consequences for these sentinel ecosystems. Previous work on a keystone zooplankton grazer, the obligatory parthenogenetic Daphnia pulicaria, from a lake in South-West Greenland [...]
A national checklist for monitoring Portugal’s pollinators (Anthophila, Syrphidae and Papilionoidea) under the EU Nature Restoration Regulation
Published: 2026-08-07
Subjects: Life Sciences
1. Wild pollinators are declining across Europe, prompting new policy commitments. The EU Nature Restoration Regulation requires Member States to reverse pollinator decline and to monitor pollinator abundance and species richness. Effective implementation depends on robust national taxonomic baselines that define which species are present, where they occur and how they can be monitored [...]
EcoScape: Species-specific Functional Habitat Connectivity Via Efficient Parallel Propagation Simulations
Published: 2026-08-07
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology
Well-connected habitats sustain viable populations through gene flow, repopulation potential, and functional habitat extent. Conserving and enhancing habitat connectivity has been identified as a priority to halt extinctions and safeguard 30% of the planet. Conservation prioritization would therefore benefit from habitat connectivity modeling that is applicable at broad spatial and taxonomic [...]
Characterization of Haplosporidium pinnae's biogeographical distribution by means of Ecological Niche Modelling techniques and consequences of climate change upon its range
Published: 2026-08-07
Subjects: Ecology and Evolutionary Biology
This study provides a biogeographical characterization of protozoan endoparasite Haplosporidium pinnae's distribution following the associated Mass Mortality Event of endangered bivalve Pinna nobilis in 2016. The epizootic has reached mortality rates between 80% - 100% and was first reported in the south-western Mediterranean Sea. It has since spread to north-western waters, followed by the [...]

Seeking to explore the impact of developmental activities on plant biodiversity, a survey was embarked upon to document plant species naturally occurring on the College of Education (now University of Delta), Agbor, Delta State, Nigeria. A total of 48 species were recorded on Campus I, and 54 species were recorded on Campus II, belonging to 20 and 26 families respectively. On Campus I, the family [...]
Existem "Biomas Brasileiros"? O Uso Do Termo No Brasil E Suas Implicações Para A Ciência E Para A Conservação Da Biodiversidade
Published: 2026-08-07
Subjects: Other Ecology and Evolutionary Biology
The term "Biome" is widely disseminated in Brazil and is frequently used in Brazilian textbooks, supplementary educational books, scientific literature and federal, state and municipal laws. Despite the definitions brought by science for this term, which consider geographic and biotic criteria, the circumscription used for biomes in Brazil lacks a more consistent technical and scientific basis, [...]
