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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
A Survey of the Terrestrial Angiospermic Indigenous Flora of College of Education, Agbor, Delta State, Nigeria
Published: 2026-08-07
Subjects: Ecology and Evolutionary Biology, Plant Sciences
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 [...]
How (not) to study insect microbiota in the age of high-throughput sequencing
Published: 2026-08-06
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Environmental Microbiology and Microbial Ecology Life Sciences
The recognition of microbiota as a critical component of insect biology and evolution has driven a rapid expansion of insect-microbe interaction research. Yet while high-throughput sequencing has democratized access to microbial community profiling, it has also normalized low-resolution, artifact-prone approaches that often yield limited biological insights. Insects pose distinct challenges for [...]
Dark invasions as cryptic components of biological invasions
Published: 2026-08-05
Subjects: Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Understanding and managing biological invasions typically requires knowledge of species records, known impacts, recognized pathways and definitions of non-native status, yet this information is rarely complete or without uncertainties. We develop the concept of dark invasions to describe a suite of hidden or underacknowledged aspects of biological invasions that are rarely quantified because [...]
Influence of Selected Urban Tree Species on Soil Microbial Activity, Litter Decomposition, and Soil Chemical Properties in Akure, Southwestern Nigeria
Published: 2026-08-05
Subjects: Agriculture, Ecology and Evolutionary Biology, Forest Sciences, Other Life Sciences, Plant Sciences
Urban trees shape belowground ecological processes through litter deposition, root exudation, and interactions with soil microbial communities, yet species-specific effects are rarely incorporated into urban green-space management. This study evaluated the effects of five common urban tree species (Eucalyptus globulus, Azadirachta indica, Thuja occidentalis, Prunus dulcis, and Buddleja globosa) [...]
Life-history traits do not always evolve in response to changing thermal environments
Published: 2026-08-04
Subjects: Biodiversity, Biology, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Integrative Biology, Zoology
Quantifying animals' capacity to evolve in response to changing environments is central to predicting ecological responses to climate change. However, empirical evidence for evolutionary responses to changing temperatures remains mixed, and we know little about how selection alters trait variance or generates trade-offs among traits. Here, we conducted a systematic review and meta-analysis of 44 [...]

Patterns of Gray Wolf and White-tailed Deer Movement: Local, County and Regional Camera-trap Data (2018-2025)
Published: 2026-07-31
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
The gray wolf (Canis lupus) is the apex predator of white-tailed deer (Odocoileus virginianus), but on a single restored site it can be too rare to study. A year-round survey of about ten cameras at nine fixed stations on an approximately 100-ha prairie–savanna complex located within Washburn County, Wisconsin, yielded too few wolf detections over three years (11,473 animal detections, 2024–2026) [...]
