Herbarium specimens reveal long-term decline in pollination services since in the 1970s
Published: 2025-08-22
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Environmental Monitoring, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
Anthropogenic change has resulted in pollinator decline and altered plant-pollinator interactions. This may drive widespread declines in pollination and reproductive success of plants, yet few datasets allow us to track changes in pollination services over time. Herbaria provide a unique opportunity to assess pollination services across broad spatial and temporal scales, and the associated [...]
Progress toward sustainable management of marine crustacean fisheries
Published: 2025-08-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Marine Biology, Natural Resources and Conservation, Natural Resources Management and Policy, Population Biology
Marine crustacean capture fisheries have been contributing increasingly more to global aquatic food production in recent decades, helping secure socioeconomic benefits. In the past decade the landings of marine crustaceans rose by more than 67% while expanding spatially and taxonomically, doubling their contribution to global fisheries landings. Although efforts to improve the data collection [...]
Shaping the future of ecological restoration: Integrating predictability and adaptive insights
Published: 2025-08-06
Subjects: Environmental Indicators and Impact Assessment, Forest Management, Natural Resources and Conservation, Other Environmental Sciences, Other Forestry and Forest Sciences
Introduction: Ecological restoration must move beyond fixed historical baselines to face the realities of climate change, biodiversity loss, and complex socioecological dynamics. Framework for restoration: We propose the Future-Based Approach (FaBRestor), a novel framework that reframes restoration as a forward-looking, adaptive process. FaBRestor integrates multitemporal lenses—past legacies, [...]
Causal models as a scientific framework for next-generation ecosystem and climate-linked stock assessments
Published: 2025-07-31
Subjects: Biostatistics, Ecology and Evolutionary Biology, Environmental Sciences, Marine Biology, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Terrestrial and Aquatic Ecology
Rapid changes in marine ecosystems highlight the need to account for time-varying productivity in stock assessment models used to support fisheries management. Common approaches incorporate annual variation or regress processes like recruitment, natural mortality, or growth on environmental covariates. While the latter represents a step towards biological realism, it often fails accounting for [...]
Mapping disturbance across California’s rapidly changing forests
Published: 2025-06-12
Subjects: Environmental Monitoring, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability
Disturbances shape assemblages and spatial patterns of flora and fauna across the globe, and accurate disturbance mapping can aid conservation science and decision-making. However, mapping and differentiating among disturbance types using remote sensing is challenging, especially in forests with hidden subcanopy disturbances. On federal lands in the western US, wildfire, drought, and fuels [...]
Marine Conservation Leadership: Does Australia Deserve a Spot on the Podium?
Published: 2025-06-10
Subjects: Natural Resources and Conservation
Australia’s marine biodiversity is unmatched, and its conservation has been prominently championed over the past three decades by successive Federal and State governments, who have consistently portrayed the nation as a global leader in marine protection. Here, we question whether this reputation is justified. We highlight substantial—and in some cases catastrophic—declines in marine species and [...]
Nature requires investment: applying Priority Threat Management to support biodiversity and climate targets
Published: 2025-05-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Natural Resources and Conservation, Natural Resources Management and Policy
1. Stemming biodiversity loss requires greater investment in conservation and more efficient use of available resources. Prioritizing conservation actions that yield the most biodiversity benefit for the least cost can help maximize return on investment. Actions that have co-benefits for other objectives, such as climate change mitigation, can also help mobilize additional funds for [...]
Decline of the globally rare old-growth specklebelly lichen, Pseudocyphellaria rainierensis, and its implications for temperate rainforest conservation
Published: 2025-04-25
Subjects: Biodiversity, Botany, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Forest Biology, Forest Management, Natural Resources and Conservation, Population Biology
Epiphytic lichens are key components of temperate rainforests, where they contribute to forest hydrology, nutrient cycles, food webs, and overall biomass and biodiversity. Despite their ecological importance and sensitivity to environmental change few protections exist for lichen conservation and management. Pseudocyphellaria rainierensis, or old-growth specklebelly lichen, is considered an [...]
A systems perspective: How social-ecological networks can improve our understanding and management of biological invasions
Published: 2025-04-03
Subjects: Ecology and Evolutionary Biology, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability
Reversing biodiversity loss and the sustainability crisis requires approaches that explicitly consider human-nature interdependencies. Social-ecological networks (SENs), which incorporate social and ecological actors and entities as well as their interactions, are such an approach. SENs have been applied to a range of complex issues, such as sustainable resource use, management of ecosystem [...]
Validating causal inference in time series models with conditional-independence tests
Published: 2025-03-17
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Marine Biology, Natural Resources and Conservation, Population Biology, Sustainability
Ecologists often use time-series models to approximate dynamics arising from density dependence, species interactions, community synchrony, and other processes. Dynamic structural equation models can represent simultaneous and lagged interactions among variables with missing data, and therefore encompasses a wide family of analyses (linear regression, vector autoregressive models, and dynamic [...]
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 [...]
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 [...]

Lampreys (Petromyzontiformes) are an ancient group of fishes with complex life histories. We created a life cycle model that includes an R Shiny interactive web application interface to simulate abundance by life stage. This will allow scientists and managers to connect available demographic information in a framework that can be applied to questions regarding lamprey biology and conservation. We [...]
