Global biodiversity measurement to meet scale-dependent needs and opportunities
Published: 2025-10-02
Subjects: Biodiversity, Business, Ecology and Evolutionary Biology, Environmental Studies, Life Sciences, Social and Behavioral Sciences
In the face of rapid ecological decline, biodiversity information is essential for safeguarding life on Earth. Although this information is increasingly valued by governments, businesses, and other stakeholders, it remains insufficiently accessible and usable. Because the rarity and functions of biodiversity vary greatly across land- and seascapes, the global and local ecological and social [...]
Extensive climate-induced range shifts in butterflies across the globe
Published: 2025-09-30
Subjects: Biodiversity, Terrestrial and Aquatic Ecology
Ongoing global change is leading to widespread species redistribution1,2. Range shift attribution, however, remains poorly resolved, partly due to the strong variation in range shift detection signals in space, over time and across the tree of life2. We compiled range shift data in 15 languages and with expert assessments, encompassing 1,758 butterfly species from 109 countries (~10% of the known [...]
Native bee genus diversity within bee-friendly urban gardens varies little along an urbanization gradient
Published: 2025-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology
Urban bee populations are threatened by ongoing habitat loss and fragmentation. Bee-friendly gardens with abundant forage and nesting resources may help offset these pressures, but attributes of the broader urban landscape could also play an important role. We explored bee diversity within 32 bee-friendly gardens distributed throughout the city of Kelowna, British Columbia. Our objectives were to [...]

Climate change is threatening plant health and productivity at all spatial scales, and these impacts are further compounded by the rising incidence of invasive pests and pathogens. Effectively addressing these challenges requires a comprehensive understanding of plant demography as well as the mechanisms and drivers of adaptation. Achieving this understanding requires the integration of [...]
Building bridges between ecological and economic agent-based models of agriculture
Published: 2025-09-26
Subjects: Agricultural and Resource Economics, Agriculture, Biodiversity, Environmental Studies
Agriculture is a complex social-ecological system with numerous interactions and feedbacks between policies, markets, farm management, landscapes, and ecosystems. Because of these interconnections, policy changes, societal trends, and environmental crises can have widespread knock-on effects that threaten the stability of the entire system. Agent-based models have become a valuable tool used for [...]
The past, present and future of online biodiversity knowledge systems

Subjects: Biodiversity, Life Sciences
In recent decades, there has been an exponential increase in the availability and accessibility of biodiversity data and a profusion of portals, tools, and platforms through which to utilise it. This reflects the extensive variety of challenges biodiversity data is being used to address and the need to enhance decision-making by different stakeholder groups. Whilst this has provided unprecedented [...]
GhostNetZero: AI for Detecting Marine Ghost Nets
Published: 2025-09-23
Subjects: Artificial Intelligence and Robotics, Biodiversity, Databases and Information Systems, Environmental Monitoring, Marine Biology, Research Methods in Life Sciences, Sustainability
Abandoned, lost, or otherwise discarded fishing gears (ALDFG), commonly referred to as ghost nets, pose a persistent global threat to marine biodiversity. Constructed from durable synthetic polymers, ghost nets remain intact for decades, continuing to entangle and kill marine organisms while damaging habitats and imposing economic burdens on fisheries and coastal communities. Despite their [...]
A Unified and Predictive Measure of Functional Diversity
Published: 2025-09-20
Subjects: Biodiversity, Ecology and Evolutionary Biology
Despite the critical role of functional diversity (FD) in understanding ecological systems and processes, its robust quantification remains a significant challenge. A long-held view in the field is that it is not possible to capture its three facets---functional richness, functional divergence, and functional evenness---in a single index. This perspective has prompted recent proposals for FD [...]
What defines an urban butterfly? Life history traits and habitat associations of butterflies in urban environments
Published: 2025-09-20
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Forest Sciences, Life Sciences
Urban areas are encroaching onto semi-natural areas the world over, driving species assemblages into homogenisation. A better understanding of the life history and habitat association traits can help support management efforts to improve urban biodiversity. Urban areas present an ecological filter, limiting the number of species present compared to the wider countryside. What characteristics help [...]
Vendi Information Gain for Active Learning and its Application to Ecology
Published: 2025-09-15
Subjects: Artificial Intelligence and Robotics, Biodiversity
While monitoring biodiversity through camera traps has become an important endeavor for ecological research, identifying species in the captured image data remains a major bottleneck due to limited labeling resources. Active learning—a machine learning paradigm that selects the most informative data to label and train a predictive model—offers a promising solution, but typically focuses on [...]
Cenozoic losses of tree diversity constrain climatic adaptation of Western and Central European forests
Published: 2025-09-10
Subjects: Biodiversity, Forest Management, Terrestrial and Aquatic Ecology
Paleoclimatic changes during the late Cenozoic led to substantial losses of tree diversity in Western and Central Europe. A modern synthesis linking which taxa were lost, the timing of these losses, and their implications for the adaptation of the region’s forest ecosystems to ongoing climate change is needed. Here, we compile a dataset of fossil occurrences of tree genera from Western and [...]
