A toolbox to quantify human activity in protected areas for park management
Published: 2024-08-26
Subjects: Biodiversity
1. Recreation in protected areas (PAs) is growing worldwide, potentially conflicting with wildlife and ecosystem protection. Efficiently estimating human activity in PAs is crucial for balancing a dual mandate of supporting visitor access and biodiversity, but managers lack clear recommendations about how best to monitor spatial and temporal trends in human activity. 2. Through two case [...]
Current knowledge on the novel semiarid photovoltaic ecosystems and their impacts on biodiversity
Published: 2024-08-26
Subjects: Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology
The transition from fossil fuels to renewable energy sources is fundamental to mitigate the effects of global climate change. Renewable power capacity is increasing globally, and solar photovoltaic will be the dominant renewable energy source by 2050. Photovoltaic parks require great extensions of land, usually in drylands. But both ecosystems created by solar parks and the effect of solar parks [...]
PPSDB : A Linked Open Data knowledge base for protist-prokaryote symbiotic interactions
Published: 2024-08-26
Subjects: Biodiversity, Environmental Microbiology and Microbial Ecology Life Sciences
As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge. Here we present the Protist-Prokaryote Symbiosis Database (PPSDB), comprising 789 manually curated interaction statements [...]
The macroecology of knowledge: Spatio-temporal patterns of name-bearing types in biodiversity science
Published: 2024-08-12
Subjects: Biodiversity, Life Sciences
Ecological and evolutionary processes are recognized as the main factors generating and maintaining biodiversity. However, how biodiversity knowledge is collated, organized, and distributed worldwide influences our perceptions and inferences about biodiversity and the underlying processes. We demonstrated that name-bearing type specimens (NBT), the most fundamental reference for the identity of [...]
An integrated population modelling workflow for supporting mesopredator management
Published: 2024-08-01
Subjects: Applied Statistics, Biodiversity, Biostatistics, Ecology and Evolutionary Biology, Longitudinal Data Analysis and Time Series, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Survival Analysis, Terrestrial and Aquatic Ecology, Zoology
Expanding populations of mesopredators threaten biodiversity and human health in many ecosystems across the world. Lethal control through harvest is commonly implemented as a mitigation measure, yet the effects of harvest and its interaction with environmental conditions on mesopredator population dynamics have rarely been assessed quantitatively due to data constraints. Recent advances [...]
New frontiers in AI for biodiversity research and conservation with multimodal language models
Published: 2024-08-01
Subjects: Biodiversity
The integration of Artificial Intelligence (AI) into biodiversity research and conservation is growing rapidly, demonstrating great potential in reducing the intensive human labor required for data preprocessing, thereby, facilitating larger data collections that offer ecological insights at unprecedented scales. However, most of these AI applications for biodiversity are still in the early [...]
Seasonal Migrants and Traditional Ecological Knowledge in a Region of Risk: The Pulse Seine Fisheries in Limfjorden, Denmark, c. 1740-1860
Published: 2024-07-31
Subjects: Aquaculture and Fisheries Life Sciences, Arts and Humanities, Biodiversity, Economic History, Environmental Studies, Marine Biology, Other Arts and Humanities, Terrestrial and Aquatic Ecology
This article presents the commercial scale and organization of the Danish pulse seine eel fishery in the Limfjord before the advent of modern offshore fisheries. Partly, for environmental concerns, the pulse seine fishery was tightly regulated, with every seine having to be checked and certified by the local district bailiffs. Here, we present the first in-depth analysis of all preserved [...]
Ongoing collapse of avifauna in temperate oceanic islands close to the mainland in the Anthropocene
Published: 2024-07-30
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Life Sciences
1. Oceanic island ecosystems are highly vulnerable to human activity. Furthermore, oceanic islands close to the mainland provide distinct perspectives on natural processes, including overseas dispersal from the mainland. However, the effects of overseas dispersal and human activity on insular community changes have not been empirically demonstrated. 2. To clarify the mechanisms driving changes in [...]
Spatial occurrence records and distributions of tropical Asian butterflies
Published: 2024-07-27
Subjects: Biodiversity, Entomology
Insect biogeography is poorly documented globally, particularly in the tropics. Recent intensive research in tropical Asia, combined with increasingly available records from citizen science, provides an opportunity to map the distributions of tropical Asian butterflies. We compiled a dataset of 724,247 occurrences of 3,591 tropical Asian butterfly species by aggregating records from GBIF (651,285 [...]
Emergent relationships between the functional diversity of marine zooplankton and ecosystem functioning in the global ocean
Published: 2024-07-23
Subjects: Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology
Copepods are a major group of the mesozooplankton and thus a key part of marine ecosystems worldwide. Their fitness and life strategies are determined by their functional traits which allow different species to exploit various ecological niches. The range of functional traits expressed in a community define its functional diversity (FD), which can be used to investigate how communities utilize [...]
Bimodal seasonal activity of moths and elevation, weather and land use as drivers of their diversity
Published: 2024-07-23
Subjects: Biodiversity, Entomology, Life Sciences, Terrestrial and Aquatic Ecology
Moths are an important part of terrestrial insect diversity and contribute substantially to ecosys-tem functioning. Yet, how their activity varies with the season and how different biotic and abiotic factors (elevation, weather, land use) are simultaneously linked to moth community characteristics are still poorly understood. We analysed a vast moth community dataset from Switzerland collected by [...]
Accelerating ecosystem monitoring through computer vision with deep metric learning
Published: 2024-07-19
Subjects: Biodiversity, Life Sciences
Feature extraction from environmental observation data based on deep learning models has made significant progress. However, the current methods may not be optimal because of the increasing volume of data, complexity of data characteristics, and labeled data limitations. In this study, we focused on deep metric learning as a new application for environmental observation data to overcome these [...]
Mapping migratory routes: Avian conservation-focused opportunities for a pan-European automated telemetry network
Published: 2024-07-17
Subjects: Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology
Accelerated biodiversity loss during the Anthropocene has destabilised functional links within and between ecosystems. Migratory species that cross different ecosystems on their repeated journeys between breeding and non-breeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem-specific threats. As these bring both lethal and non-lethal [...]
Assisted colonisation for ecosystem function: a thought experiment for the British Isles
Published: 2024-07-17
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Climate change is driving the rapid reorganisation of the world’s biota as species shift their ranges to track suitable conditions, however habitat fragmentation and other barriers hinder this adaptive response for species with limited dispersal ability. The translocation of species into newly suitable areas to which they are unable to disperse naturally has been suggested to conserve species [...]
