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 [...]

The “Water for Birds Tool” is a spreadsheet-based model (using Microsoft Excel) designed to help resource managers assess the spatial extent and types of bird habitats in the Malheur National Wildlife Refuge. The model quantifies the areas of open water, partial water, and water depths on a monthly timescale during the irrigation season (April–July) from 2021–2024. This model combines previously [...]
Widespread loss of important ecosystem services from rapidly urbanising Kathmandu Valley
Published: 2024-10-20
Subjects: Environmental Sciences
Ecosystem services are crucial for human well-being as it offers benefits such as food production, water purification, and climate regulation. However, land use change caused by rapid urban expansion poses a significant threat to these services. We investigate the impact of urbanization on ecosystem services in the Kathmandu Valley, a region experiencing intense urban growth. We assessed changes [...]
Climate-linked escalation of societally disastrous wildfires
Published: 2024-10-18
Subjects: Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences
Climate change is forcing societies to contend with increasingly fire-prone ecosystems. Yet, despite evidence of more extreme fire seasons, evidence is lacking globally for trends in wildfires with socially and economically disastrous effects. Using a systematic dataset, we analyse the distribution, trends, and climatic conditions connected with the most lethal and costly wildfire disasters from [...]
Ambitions in national plans do not yet match bold international protection and restoration commitments
Published: 2024-10-17
Subjects: Environmental Law, Environmental Sciences
Almost 200 nations have made bold commitments to halt biodiversity loss as signatories to the Kunming-Montreal Global Biodiversity Framework (‘GBF’). The effective achievement of the GBF relies on domestic targets and actions, reflected in National Biodiversity Strategies and Action Plans (‘NBSAPs’). NBSAPS are an integral feature of the Convention on Biological Diversity (‘CBD’) framework, and [...]
Is the audience gender-blind? Smaller attendance in female talks highlights imbalanced visibility in academia
Published: 2024-05-27
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Evolution, Gender Equity in Education, Higher Education, Inequality and Stratification, Other Ecology and Evolutionary Biology, Psychological Phenomena and Processes
Although diverse perspectives are fundamental for fostering and advancing science, power relations have limited the development, propagation of ideas, and recognition of political minority groups in academia. Gender bias is one of the most well-documented processes leading women to drop out of their academic careers due to fewer opportunities and lower recognition. Using decadal-scale data on [...]
