Biodiversity footprint of public procurement in Finland
Published: 2026-02-06
Subjects: Biodiversity, Environmental Indicators and Impact Assessment, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics
Halting biodiversity loss requires systematic action from all sectors of society. The public sector is a significant actor globally in creating markets for goods and services, public procurement representing on average 13 – 20% of national gross domestic product. In this study, we assessed the biodiversity footprint of public procurement in Finland for years 2021 and 2022. We applied the [...]
The origins and diversification of hummingbird pollination in Bromeliaceae
Published: 2026-02-06
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology, Evolution, Plant Sciences
Bromeliaceae are a model group for understanding explosive Neotropical diversification, combining remarkable ecological breadth and high species richness, despite relatively recent evolutionary origins. Multiple drivers are hypothesised to accelerate bromeliad diversification, and hummingbird pollination is frequently proposed to be among the strongest. However, our understanding has been limited [...]
The conditional ecology of pest suppression: A general mechanistic framework for predicting landscape effects on biological control
Published: 2026-02-03
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology
Landscape heterogeneity often increases natural enemy abundance, yet its effects on crop pest suppression are strikingly inconsistent across empirical studies. We developed a trait-based simulation framework to identify the general mechanisms linking landscape structure to realized pest load. Across >150 in silico experiments, we show that landscape attributes influence biological control by [...]
Factors influencing the use of scientific evidence in conservation practice and policy: insights from a systematic map
Published: 2026-02-02
Subjects: Biodiversity, Life Sciences, Social and Behavioral Sciences
Evidence-based conservation can lead to better outcomes for biodiversity, through the integration of scientific evidence with other forms of knowledge to make transparent and effective decisions. However, despite efforts to promote evidence-based practice, many management and policy decisions do not incorporate scientific information. To strengthen the interface between science and [...]
The true scope of global wildlife trade is obscured by data gaps
Published: 2026-01-29
Subjects: Biodiversity, Ecology and Evolutionary Biology
Overexploitation of wildlife is a major driver of biodiversity loss. International wildlife trade is regulated and monitored at local, national, regional and global scales through a variety of mechanisms, including Multilateral Environment Agreements (MEAs), with CITES playing a key role. Whilst databases and systems are available to measure, monitor, and manage legal trade, the data for species [...]
Inspiring systematic inclusion of individual animal states to enhance the quality of research
Published: 2026-01-23
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology
Studies on animals continue to attract criticism over data quality, reproducibility and generality of findings, yet one source of variation remains rarely addressed: differences in individuals’ affective states. In this paper, we suggest that evaluating affect should be considered standard good practice in ecological and behavioural research with wild animals, alongside familiar variables such as [...]
Seasonal camouflage as a model to understand the scope for rapid adaptation in a changing world
Published: 2026-01-23
Subjects: Biodiversity, Ecology and Evolutionary Biology, Molecular Biology
Human-driven environmental change is reshaping ecosystems and challenging species’ ability to adapt. Understanding how genetic variation enables adaptation is crucial for conservation and requires exemplary systems to test hypotheses and make predictions. One particularly suitable model for studying climate-driven adaptation is seasonal color change (SCC), a phenological trait in which [...]
Understanding the dimensions and gaps in wildlife health surveillance for zoonotic risk management
Published: 2026-01-23
Subjects: Agriculture, Biodiversity, Immunology and Infectious Disease
Following the Covid 19 pandemic, One Health has been a topic of increasing global awareness, with the development of various global strategies and action plans to manage and counteract risks as well as identify potential risks. However, despite these calls for action, little work has been conducted to establish a global baseline on policies related to One Health, particularly dealing with the [...]
Supporting wildlife movement amid the rise of border infrastructure
Published: 2026-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Law, Environmental Studies, Forest Management, Nature and Society Relations, Zoology
Transboundary areas of conservation importance affected by border infrastructure and militarization urgently need connectivity conservation solutions. Where human conflicts are ongoing and peace initiatives may be unviable, smaller-scale approaches can still be implemented. We propose a multi-faceted approach to support animal movement and minimize impacts of multiple border barriers on medium to [...]
The missing branches of the bee Tree of Life: addressing global Darwinian shortfalls and their drivers
Published: 2026-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Understanding the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) can help us to guide future biodiversity research and conservation efforts. Overcoming this shortfall is essential to develop robust strategies to preserve the Tree of Life while facing the ongoing biodiversity crisis. Here, we present the first global assessment of Darwinian shortfalls and their [...]
Wild boar population control needs more than recreational hunting
Published: 2026-01-09
Subjects: Animal Sciences, Biodiversity
This perspective addresses the challenges of wild boar (Sus scrofa) population control in two different scenarios: reactive management to control disease epidemics and proactive management of wild boar populations at larger geographic scales. Intense but silent wild boar culling can significantly contribute to local outbreak control. Larger wild boar free buffer zones might work in front-like [...]
TABMON – real-time acoustic biodiversity monitoring across Europe
Published: 2026-01-08
Subjects: Biodiversity, Life Sciences
1. Ecological surveys are often fragmented, costly, and limited in scale, leading to large and long-standing knowledge gaps which threaten our ability to properly safeguard biodiversity. 2. Passive Acoustic Monitoring (PAM) has promised to deliver automated biodiversity monitoring, but networks are rarely deployed on scales that can offer truly novel insights due to scalability and [...]
Spatial Expansion and Ecological Correlates of Invasive Crayfish Procambarus clarkii and Pacifastacus leniusculus in Mediterranean Rivers of Catalonia (NE Iberian Peninsula)
Published: 2026-01-06
Subjects: Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology
Invasive freshwater crayfish are among the most impactful non-native taxa in European river systems, yet quantitative assessments of their spatial expansion and environmental drivers remain scarce in Mediterranean regions. We investigated the expansion dynamics and environmental drivers of two invasive North American crayfish, Procambarus clarkii and Pacifastacus leniusculus, in rivers of [...]
Marine biodiversity indicators and online data knowledge systems
Published: 2026-01-06
Subjects: Biodiversity, Marine Biology
Coastal marine ecosystems and biodiversity are changing rapidly under climate forcing, resource use, pollution and habitat modification. Monitoring these changes, and tracking progress across policy targets, remain constrained by uneven data coverage, fragmented observing networks and inconsistent measurement practices. International policy frameworks, most prominently the Kunming-Montreal Global [...]
Data availability impacts the predictive accuracy of pressure-based biodiversity models
Published: 2025-12-23
Subjects: Biodiversity, Ecology and Evolutionary Biology
Amidst the biodiversity crisis, there is high demand for spatially explicit biodiversity indicators. Global models that quantify impacts of human pressures provide important insights for conservation, but their accuracy in spatial projections has yet to be systematically tested. Here we evaluate this using a global dataset of 25,987 species inventories from 681 studies. We find that mixed models [...]
