A Julia toolkit for species distribution data
Published: 2025-02-18
Subjects: Biodiversity, Other Ecology and Evolutionary Biology
(1) Species distribution modeling requires to handle varied types of data, and benefits from an integrated approach to programming. (2) We introduce SpeciesDistributionToolkit, a Julia package aiming to facilitate the production of species distribution models. It covers various steps of the data collection and analysis process, extending to the development of interfaces for integration of [...]
An influential biodiversity market may not direct investment towards habitats of national importance
Published: 2025-02-13
Subjects: Biodiversity
Biodiversity markets are proliferating globally, aiming to increase private investment to address conservation financing gaps. Markets commodify biodiversity to facilitate trade of biodiversity ‘units’ even across heterogeneous ecologies. However, the metric used to commodify biodiversity can strongly influence which habitats become valuable in biodiversity markets, and there has been little [...]
Algorithm selection for optimal ecological monitoring design
Published: 2025-02-11
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology
Comprehensive monitoring of biodiversity to direct conservation action is foundational to addressing the ongoing biodiversity crisis. As integrative monitoring programs increasingly come online in response to multilateral biodiversity agreements, establishing best practices for optimal design is critical. Selecting the appropriate algorithm for identifying sample sites is both necessary for [...]
Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks predictive trait and classification modeling in plant biodiversity collections
Published: 2025-02-10
Subjects: Biodiversity, Bioinformatics, Botany, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences
Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof-of-concept study using trait data and spectra from herbarium specimens up to 179 years old alongside data from recently dried, pressed [...]
Overcoming “doom and gloom”: Envisioning desirable futures for Arctic biodiversity
Published: 2025-02-07
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Health and Protection, Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Physical Sciences and Mathematics, Social and Behavioral Sciences, Sustainability
We co-created visions of desirable futures for Arctic biodiversity during a workshop which included representatives from academia, Indigenous Peoples, business and policy-making. Appreciating our diverse perspectives, we identified key actions that would enable the positive outcomes shared in our visions: boosting education, rethinking Arctic biodiversity governance, elevating the voices of [...]
Maximising time-series inclusion reduces geographic and taxonomic biases in the Living Planet Index
Published: 2025-02-05
Subjects: Biodiversity
Measuring how and why biodiversity is changing is critical to protecting it. Among the tools developed to measure biodiversity, one indicator has come under recent scrutiny. The Living Planet Index (LPI) is an indicator based on vertebrate population trends used as evidence for policy and a resource for scientific research; it has a high profile and global reach in the media by conveying a simple [...]
The collector practices that shape spatial, temporal, and taxonomic bias in herbaria
Published: 2025-02-05
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology
Natural history collections (NHCs) are essential for studying biodiversity. Although spatial, temporal, and taxonomic biases in NHCs affect analyses, the influence of collector practices on biases remains largely unexplored. We utilized one million digitized specimens collected in the northeastern United States from 237 herbaria and analyzed contributions from ~10,000 collectors. We investigated [...]
The business case for investing in biodiversity data
Published: 2025-02-04
Subjects: Biodiversity
1. There is urgent demand for biodiversity data driven by the need to assess impacts, dependencies, risks, and to implement nature-based solutions. In a data-driven economy, without access to robust data and the tools built from it, public and private sector actors cannot reliably evaluate their relationships with biodiversity or the outcomes of any sustainable nature-positive intervention.2. [...]
Bats in Habitats, Bats as Habitats: An integrative ecological framework for understanding synergistic interactions across levels of community organization
Published: 2025-02-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Integrative Biology, Systems Biology
Global biodiversity and ecosystem function are the result of complex networks of interactions and feedbacks between animals and their environments, which in turn are affected by the interactions and feedbacks between animals and the organisms they host. Understanding these complex networks, including the main drivers of and responses to ecological and environmental changes and their global [...]
Powerful yet challenging: Mechanistic Niche Models for predicting invasive species potential distribution under climate change
Published: 2025-01-29
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology
Risk assessments of invasive species are among the most challenging applications of species distribution models (SDMs). This challenge arises from the disequilibrium in invasive distributions, where recorded occurrences do not fully represent the species' potential range. The spatiotemporal dynamics of invasive populations are shaped by intraspecific variability, human-mediated introductions, [...]
Incorporating responses of functional traits to changing climates into species distribution models: A path forward
Published: 2025-01-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Conventional species distribution models (SDMs) typically consider only abiotic factors, thus overlooking critical biotic dimensions, including functional traits that play an important role determining species’ distributions in changing environments. Process-based models explicitly incorporate functional traits and have been applied to SDMs. However, their parameterization can be complex and [...]
Strategies to transform natural resource extension with iNaturalist and engage the public in biodiversity conservation
Published: 2025-01-13
Subjects: Biodiversity, Education, Life Sciences
Participatory citizen science is an increasingly popular tool which provides non-formal education and learning activities. iNaturalist—a free open-access—participatory citizen science platform provides a place to engage the public in natural resource programming. Here, we explore practical applications for integrating iNaturalist into extension programming. We highlight two approaches: (1) [...]
The implementation of network meta-analysis in Ecology; a case study using crop yield data
Published: 2025-01-13
Subjects: Agriculture, Biodiversity, Life Sciences, Natural Resources and Conservation, Natural Resources Management and Policy
Network meta-analysis (NMA) is a method commonly used in medical research that allows for the comparison of multiple interventions in a single, coherent analysis. In this study, we explore how NMA can be applied in ecological studies – specifically, in comparing the effectiveness of multiple interventions in field experiments. Our study aims to provide a general and non-technical introduction of [...]
