Spatially explicit predictions of food web structure from regional level data

Gabriel Dansereau, Ceres Barros, Timothée Poisot

Published: 2023-09-15
Subjects: Biodiversity, Ecology and Evolutionary Biology

Knowledge about how ecological networks vary across global scales is currently limited given the complexity of acquiring repeated data for species interactions. Yet, recent developments of metawebs highlight efficient ways to first document possible interactions within regional species pools. Downscaling metawebs towards local network predictions is a promising approach to use current data to [...]

Monitor indicators of genetic diversity from space using Earth Observation data

Meredith Christine Schuman, Claudia Röösli, Alicia Mastretta Yanes, et al.

Subjects: Biodiversity, Life Sciences

Use Earth Observation (EO) for monitoring and re- porting on the Kunming-Montreal Global Biodiversity Framework (GBF) indicators of genetic diversity. EO has high potential and practical importance for advancing biodiversity monitoring within the GBF. We propose that these advances are artificially limited by the consensus that genetic variation cannot be observed from space. Here, we [...]

Assessing the multidimensional complexity of biodiversity using a globally standardized approach

Camille Fournier de Lauriere, Robert M McElderry, Ian Brettell, et al.

Published: 2023-08-25
Subjects: Biodiversity, Life Sciences

Quantifying biodiversity across the globe is critical for transparent reporting and assessment under the Kunming-Montreal Global Biodiversity Framework. Understanding the full complexity of biodiversity requires consideration of the variation of life across genetic, species and ecosystem levels. Achieving this in a globally-standardized way remains a key international challenge for biodiversity [...]

Gardens as drivers of native plant dispersal and conservation

Published: 2023-08-25
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences

1. Gardens hold untapped potential for participatory biodiversity conservation. Conservation gardening has recently emerged as a way to foster declining native plant species in urban and rural green spaces. But the impact of cultivating these species on population trends in the broader landscape remains underexplored. 2. Here, I study the effects of cultivating herbaceous native plants on [...]

Relative abundance distributions reveal constraints on tetrapod community diversity

Neil Brocklehurst, Bethany Allen, Emma M Dunne

Published: 2023-08-22
Subjects: Biodiversity, Evolution

Previous efforts to understand the pace of species diversification through time have disagreed over whether species diversity is unbounded or limited by a carrying capacity. Tetrapods (limbed vertebrates) have frequently been employed as a case-study in examinations of this issue, with studies of diversity being used to support both sides. Here, we examine the shape of relative abundance [...]

Assessing risk of ecosystem collapse in a changing climate

Jessica A. Rowland, Emily Nicholson, Jose-Rafael Ferrer-Paris, et al.

Published: 2023-08-07
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Sciences, Life Sciences

Climate change has pervasive impacts on Earth’s ecosystems, but the diversity and complexity of ecosystems makes estimating the severity of impacts and the resulting risk of collapse difficult. In this perspective, we conceptualise the challenge of understanding how climate change alters ecosystems, and how to reliably measure those changes in ecosystem risk assessments, focussing on the IUCN Red [...]

STRyper: an open source macOS application for microsatellite genotyping

Jean Peccoud

Published: 2023-07-29
Subjects: Biodiversity, Bioinformatics, Molecular Genetics, Other Ecology and Evolutionary Biology

In the context of population genetics, microsatellite markers analyzed by capillary sequencing remain useful tools for quick genotyping and low-cost studies. This contrasts with the lack of a free application to analyze chromatograms for microsatellite genotyping that is designed for population geneticists. To fill this gap, I have developed STRyper, a macOS application whose source code is [...]

The need of decoding life for taking care of biodiversity and the sustainable use of nature in the Anthropocene - a Faroese perspective

Svein-Ole Mikalsen, Jari í Hjøllum, Ian Salter, et al.

Published: 2023-07-29
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences

Biodiversity is under pressure, mainly due to anthropocentric activities and climate change. At the international policy level, it is now recognised that genetic diversity is an important part of biodiversity. The availability of high-quality reference genomes gives the best basis for using genetics and genetic diversity towards the global aims of (i) protection of species, biodiversity, and [...]

How does dispersal shape the genetic structure of animal populations in European cities? A simulation approach

Paul Savary, Cécile Tannier, Jean-Christophe Foltête, et al.

Published: 2023-07-25
Subjects: Biodiversity, Genetics, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology

Context and objectives Although urbanization is a major driver of biodiversity erosion, it does not affect all species equally. The neutral genetic structure of populations in a given species is affected by both genetic drift and gene flow processes. In cities, the size of animal populations determines drift and can depend on multiple processes, whereas gene flow essentially depends on the [...]

Recent human-bear conflicts in Northern Italy: a review, with considerations of future perspectives

Mattia De Vivo

The killing of a runner in Northern Italy by a brown bear (Ursus arctos arctos) and the subsequent investigation of such matter highlighted a Human-Wildlife Conflict (HWC) that has been present in Trentino since the introduction of bears for conservation during the Life Ursus Project. Such conflict may be exacerbated as both human and bear populations get bigger. In this paper, I summarize the [...]

The History and Development of Small Mammal Control on China’s Grasslands and Potential Implications for Conservation

Joseph Lambert, Yujie Niu, Kun Shi, et al.

Published: 2023-07-15
Subjects: Biodiversity

Grasslands make up 40% of China’s territory and are important ecological and economic areas. The native small mammals that inhabit these grasslands are often seen as pests competing with livestock and are subjected to population control. At the same time, several species are functionally important ecosystem engineers, and their removal can have far-reaching consequences for grassland health. We [...]

Measuring historical pollution: natural history collections as tools for public health and environmental justice research

Background: Through the industrial era, environmental pollution has been unevenly distributed in the environment, disproportionately impacting disenfranchised communities. The distribution of pollution is thus a question of environmental justice and public health that requires policy solutions. However, we lack robust quantitative data on pollutants for many locations and time periods because [...]

Published: 2023-06-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology

Dispersal plays a key role in shaping spatial patterns of biodiversity, yet its spatial heterogeneity is often overlooked in biodiversity analyses and management strategies. Properly parametrized heterogeneous dispersal networks capture the complex interplay between landscape structure and species-specific dispersal capacities. This heterogeneity, however, is recurrently neglected when studying [...]

Plant diversity dynamics over space and time in a warming Arctic

Subjects: Biodiversity, Plant Biology, Terrestrial and Aquatic Ecology

The Arctic is warming four times faster than the global average, and plant communities are responding through shifts in species abundance, composition and distribution. However, the direction and magnitude of local plant diversity changes have not been explored thus far at a pan-Arctic scale. Using a compilation of 42,234 records of 490 vascular plant species from 2,174 plots at 45 study areas [...]
