Taxonomic, phylogenetic, and functional diversity of a Sierra Nevada subalpine meadow community along soil hydrological gradient
Published: 2026-07-04
Subjects: Life Sciences
Mountain meadows occupy about 2% of the Sierra Nevada Range but house many narrow endemic and imperiled species. In this study, we investigated plant community structure and assessed species, phylogenetic, and functional diversity of Dog Valley Meadow, a subalpine meadow in the northern Sierra Nevada Range, California. Variation in groundwater level creates three distinct meadow-type habitats – [...]
Drivers of temporal beta diversity and ecological resilience of plant communities across the United States
Published: 2026-07-04
Subjects: Life Sciences
Long-term monitoring surveys offer more reliable assessments of biodiversity responses to climate change. In this study, we evaluated community shifts in 1105 1 m2 plots across 20 NEON sites, representing each of the 20 eco-climatic domains across the U.S. and Puerto Rico, using long-term plant surveys (5-10 years). We computed alpha, spatial and temporal beta, and gamma diversity for the plots [...]
Rodenticides now ubiquitous in wildlife of Italian landscapes
Published: 2026-07-03
Subjects: Biochemistry, Biophysics, and Structural Biology, Ecology and Evolutionary Biology, Other Life Sciences
Second Generation Anticoagulant Rodenticides (SGARs) are used to control synantropic rodents and therefore also affect non-target wildlife. However, no study tested for their presence across a whole assemblage of wildlife, limiting our understanding of their overall circulation and exposure pathways. We tested for SGARs in a large sample of terrestrial mammals (n = 403) and birds (n = 189), that [...]
Genome-wide strengthening of evolutionary constraint across the volvocine multicellularity gradient
Published: 2026-07-03
Subjects: Computational Biology, Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Genomics
The evolutionary cost of maintaining somatic cell populations has been hypothesised to drive proteome-wide strengthening of constraint on coding sequence at the origin of multicellularity. Prior work on the volvocine clade has reported lower d_N/d_S in colonial than in unicellular relatives on 55 chloroplast genes (Hu et al. 2019) and on 105 nuclear single-copy orthogroups across colonial species [...]
Incorporating traits into consumer-resource models for a mechanistic trait ecology
Published: 2026-07-03
Subjects: Life Sciences
Traits provide a powerful way to infer community assembly processes, responses to environmental perturbations, and coexistence mechanisms, although most work has focused on plants and has not incorporated the role of trophic interactions. Here, we briefly review the main goals of trait-based ecology and highlight recent examples that use traits to study insect communities, specifically focusing [...]
Insects as agents of national security: entomological biodiversity loss and ecosystem collapse in agriculture and forestry threaten geopolitical stability
Published: 2026-07-02
Subjects: Agriculture, Biodiversity, Biosecurity, Entomology, Forest Management, Forest Sciences, Life Sciences, Policy Design, Analysis, and Evaluation, Public Affairs, Public Policy and Public Administration
1. In early 2026, the UK Government published a report assessing how global biodiversity loss and ecosystem collapse represent systematic threats to UK national security through cascading impacts to food security, land use and climate-related feedbacks. 2. Recontextualising biodiversity and ecosystem health as determinants of national security offers a novel perspective on long observed [...]
Partitioning environmental and philopatric drivers of nest site selection in an estuary-endemic turtle (Malaclemys terrapin)
Published: 2026-07-02
Subjects: Life Sciences
Abstract 1. Oviposition site selection is a critical maternal effect with direct implications for population-level adaptation to environmental change. This process is driven by a complex interplay of environmental, density-dependent, and social factors whose relative contributions to site selection are rarely quantified simultaneously. Natal philopatry, for example, is a maternal effect that can [...]
Anatomical responses of Cedrus libani (Lebanon Cedar) wood to mechanical stress
Published: 2026-07-02
Subjects: Life Sciences
Wood (secondary xylem) is a source of information about events that occurred during their lifespan. The aim of our research was to provide the pattern of modification of Lebanon cedar wood under the influence of mechanical stress, as a result of binding its trunk with string or wire. The wood samples were taken from a young Cedrus libani (14 years old - evaluated based on the number of growth [...]
Avian epigenetic clocks: state of the art and call to action
Published: 2026-07-02
Subjects: Life Sciences
DNA methylation-based epigenetic clocks are powerful biomarkers of chronological and biological age, estimating age from CpG-specific methylation patterns that integrate developmental history, environmental exposure, physiological stress, and stochastic epigenetic change. Despite rapid advances in mammals, avian epigenetic clocks remain scarce, limiting comparative inference and our understanding [...]
A global evidence synthesis of outcomes of urban bird conservation interventions
Published: 2026-07-02
Subjects: Biodiversity, Life Sciences, Ornithology
Avian populations face high concentrations of threats in urban areas. Understanding the outcomes of urban conservation interventions to tackle these threats could inform more effective evidenced-based approaches. Using an evidence synthesis and meta-analysis of peer-reviewed literature on conservation interventions to tackle four leading causes of urban bird mortality in urban areas (cat [...]
Technology should support, not sideline, locally driven conservation and restoration monitoring
Published: 2026-07-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Studies
The choice of how to monitor conservation and restoration is not solely technical – it shapes which outcomes are valued, whose priorities define success, where resources flow, and who benefits. The shift toward tech-based monitoring, driven by demand for scalable metrics, risks incomplete ecological understanding, sidelining Indigenous Peoples and Local Communities (IPLCs) from data ownership and [...]
Convergent biosynthesis of psilocybin in an ectomycorrhizal lineage: is the psychoactive end-product the selected trait?
Published: 2026-07-01
Subjects: Life Sciences, Medicine and Health Sciences
The fungivore-deterrence hypothesis, that psilocybin evolved as a chemical defence against arthropod fungivores via 5-HT receptor agonism, has become the working consensus in fungal chemical ecology, despite resting on a phylogenomic pattern of horizontal gene transfer among saprotrophs and remarkably little direct experimental evidence. Recent biochemistry shows that the ectomycorrhizal Inocybe [...]
Bridging nutritional geometry and network ecology to quantify the robustness of nutritional networks
Published: 2026-07-01
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Nutrition, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
Understanding the robustness and resilience of ecological networks is key to managing ecosystems and mitigating biodiversity loss. Simple models of network robustness simulate species losses across ecological networks but lack physiological realism, asserting that species persist if they interact with another organism. This neglects the nutritional consequences of resource loss and nutrition as a [...]
Taming the dragon: genetic variation in wild and domesticated Antirrhinum majus
Published: 2026-06-30
Subjects: Botany, Genetics, Genetics and Genomics, Horticulture, Life Sciences, Plant Sciences
Domesticated species and their wild relatives provide powerful case studies for examining the processes that shape rapid diversification. Here, we conduct a population genetic analysis of 31 domesticated varieties and 33 natural populations of the common snapdragon, Antirrhinum majus, a species in which closely related flower colour varieties form hybrid zones and display extensive variation in [...]
Species diversity reduces risk in tropical forest restoration: a portfolio effect across heterogeneous sites
Published: 2026-06-30
Subjects: Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Assisted restoration is essential for recovering degraded tropical forests. Biodiversity-stability theory predicts that functionally diverse communities should produce more reliable, predictable outcomes than monocultures, but broad-scale field experiments in tropical restoration are scarce. We established 120 plots spanning five planting treatments (two monocultures – of a fast-growing [...]
