The ecomorphological diversity of Amazonian stream fishes is constrained by phylogenetic relationships
Published: 2023-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Phylogenetic history and environmental conditions determine trait diversity of species pools. Stream fishes have diversified into a wide range of body and oral shapes that allow a similarly wide range of functional traits that are related to resource use and phylogenetic closeness. Herein, we analyzed 16 ecomorphological traits of nearly 400 fishes inhabiting streams distributed across the [...]
Additional notes on the taxonomy of Parakeelya Hershk. (Montiaceae)
Published: 2023-09-30
Subjects: Biodiversity
Parakeelya Hershk. (Montiaceae) has become the name conserved over the older name Rumicastrum Ulb. for a lineage of Australian plants historically classified in Calandrinia Kunth. In Candollean taxonomy persistent to the late 20th Century, Australian plants were classified in a large, heterogeneous, and polyphyletic circumscription of Calandrinia, later referred to by the designation [...]
Spatially explicit predictions of food web structure from regional level data
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 spatial 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 [...]
Monitor indicators of genetic diversity from space using Earth Observation data
Published: 2023-09-15
Subjects: Biodiversity, Life Sciences
By providing images of the globe, measured frequently across several optical domains, in the form of public data, EO has high potential to facilitate and advance biodiversity monitoring. However, there is currently a consensus that EO cannot contribute to monitoring genetic diversity. Here, we challenge this consensus by explaining how EO can help to develop the headline and complementary [...]
Assessing the multidimensional complexity of biodiversity using a globally standardized approach
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 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. Here, we present the [...]
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
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
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
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
Published: 2023-07-29
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Biodiversity is under pressure, mainly due to human 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 nature, and [...]
How does dispersal shape the genetic patterns of animal populations in European cities? A simulation approach
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
Published: 2023-07-17
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Zoology
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
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 [...]
