The roles of contrasting host types on the environmental abundance of Anaplasma phagocytophilum, an emerging zoonotic pathogen
Published: 2026-07-09
Subjects: Life Sciences
Fundamental knowledge of the role of hosts in shaping vector-borne pathogen abundance is critical to understanding the ecology of these disease systems; yet the roles can be challenging to tease apart, especially for pathogens vectored by generalist feeders with multiple hosts. In this study, we aimed to quantify the relative contributions of hypothesised pathogen transmission hosts (deer and [...]
From Scalable Biodiversity Measurement to Credible Biodiversity Metrics

Governments struggle to develop effective policies to counter the decline of species and ecosystems. An obstacle to command-and-control and incentive-based mechanisms is that biodiversity is costly to measure, creating an information asymmetry in which firms and governments are incentivised to withhold information on adverse impacts. Using a principal-agent model, we show that credible reporting [...]
A comprehensive dataset on plant-associated invertebrates and gardening activities, from 100 sites across five urban green space types in Zurich, Lugano, and Geneva, Switzerland
Published: 2026-07-09
Subjects: Life Sciences
This dataset describes plant-associated invertebrates, gardening activities, and habitat diversity across five urban green spaces (UGS) types in the cities of Zurich, Lugano, and Geneva, Switzerland. The UGS types, namely allotment lot, private garden, residential estate, park, and ruderal area, cover different purposes, ownership, and management regimes. While Zurich was the core study region, [...]
Threat intensification reshapes trait-response relationships in birds and mammals
Published: 2026-07-09
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Predicting which species are most at risk of extinction, and by which threats, is central to effective biodiversity management (1). Trait-based frameworks, linking species traits to extinction risk, are increasingly used to predict global biodiversity trends, with applications from species-specific prioritisations (2) to estimations of global diversity loss (3). However, despite the strong [...]
Cetaceans of the Black and Azov Seas as Indicators of Habitat Quality via Stacked Species Distribution Models
Published: 2026-07-07
Subjects: Life Sciences
Habitat degradation and biodiversity loss in the Black and Azov Seas necessitate improved tools for spatially explicit conservation planning. We employed stacked species distribution modelling (SSDM) to assess habitat quality for the three resident cetacean species—the common dolphin (Delphinus delphis ponticus), the bottlenose dolphin (Tursiops truncatus ponticus), and the harbour porpoise [...]
Timing isn’t everything: impacts of maximum abundance and duration of a seasonal resource on consumer fitness
Published: 2026-07-07
Subjects: Life Sciences
Phenological advances are among the most apparent biotic responses to warmer springs in mid- to high-latitude regions, with evidence that consumers are advancing less than the resources they rely on. Here, we extend the match/mismatch hypothesis to predict how the mean timing, maximum abundance and duration of the resource phenological distribution impacts on consumer fitness. Using data from 44 [...]
From a review to the field: Alternative coping styles under urbanisation

Under human-induced rapid environmental changes, behavioural and physiological responses of organisms are key to maintain homeostasis and minimise fitness loss. Both responses can be integrated, into among-individual correlations forming stress-coping styles or syndromes (SCS). Such SCS emerge from genetic correlations or adaptive trade-offs. In the context of environmental challenges, more [...]
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 [...]
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

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 [...]
