Datathons: fostering equitability in data reuse in ecology
Published: 2024-04-04
Subjects: Biodiversity, Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Genetics, Genetics and Genomics, Genomics, Life Sciences, Microbiology
Approaches to rapidly collect global biodiversity data are increasingly important, but biodiversity blindspots persist. We organized a three-day Datathon event to improve the openness of local biodiversity data, and facilitate data reuse by local researchers. The first Datathon, organized among microbial ecologists in Uruguay and Argentina assembled the largest microbiome dataset in the region to [...]
No place for phylogeny in structuring a sandy coastal plain community
Published: 2024-04-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences
Although inference of assembly processes from phylogenetic patterns has become ubiquitous in community ecology, surprisingly few studies simultaneously test assumptions of such an approach and integrate over spatial scales and plant life stages. Here we investigate the roles of phylogeny, functional traits, and abiotic conditions in the spatial structuring of a sandy coastal plain community using [...]

Pollination across the diel cycle: a global meta-analysis
Published: 2024-03-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Yet, despite over six decades of research into whether plant reproductive success varies between day and night, consensus remains elusive. We compiled and analysed the [...]
Incomplete lineage sorting and hybridization underlie of tree discordance in Petunia and related genera (Petunieae, Solanaceae)
Published: 2024-03-29
Subjects: Biodiversity, Bioinformatics, Botany, Genomics
Despite the overarching history of species divergence, phylogenetic studies often reveal distinct topologies across regions of the genome. The sources of these gene tree discordances are variable, but incomplete lineage sorting (ILS) and hybridization are among those with the most biological importance. Petunia serves as a classic system for studying hybridization in the wild. While field studies [...]
Lianas, to cut or not to cut to conserve forest biodiversity?
Published: 2024-03-16
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences
Although lianas play an important role in forest composition, structure, and functions, they are considered structural parasites of trees. Both contrasting ideas on the role of lianas in forests challenge practitioners during restoration activities and management decisions might be taken without specific information. Here we evaluated the effects of lianas on their host-trees in a small [...]
Satellite images reveal major discrepancies between mapped and operating wind turbines in a hotspot of wind energy development
Published: 2024-03-12
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Wind energy is an emerging challenge for biodiversity conservation, due to its impacts on habitats and species. Therefore, effective mitigation and zonation policies require accurate maps of operating wind turbines. However, the current pace of wind energy development raises doubts on how fast existing maps can become obsolete. We used freely available satellite imagery from Google to check the [...]
Desafíos y barreras para la disponibilización de datos abiertos de biodiversidad en Uruguay
Published: 2024-03-06
Subjects: Biodiversity, Public Policy
Los nuevos desafíos que plantea el cambio global tornan urgente contar con datos de calidad que nos permitan monitorear la biodiversidad y frenar su pérdida. Sin embargo, en la actualidad, el Estado Uruguayo y sus diferentes Ministerios no disponibilizan datos primarios; tampoco existe información abierta disponible sobre los ejemplares de las colecciones nacionales, ni existen políticas [...]
Social cues and habitat structure influence the behavior of a non-social insect
Published: 2024-03-05
Subjects: Agriculture, Animal Sciences, Biodiversity, Entomology, Life Sciences
Habitat fragmentation and loss is a known threat to biodiversity. Their combined effect leaves organisms in small isolated patches of habitat, contributing to the current biodiversity crisis. The first response of animals to environmental change is typically behavioral. Beyond the physical elements of the environment, the "social landscape" shapes the spatial distribution of the habitats [...]
Quantifying taxon-specific habitat connectivity requirements of urban wildlife using structured expert judgement
Published: 2024-02-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Research Methods in Life Sciences
Urban planning which enhances native biodiversity in and around cities is needed to address the impacts of urbanisation and conserve urban biodiversity. The “Biodiversity Sensitive Urban Design” (BSUD) framework incorporates ecological knowledge into urban planning to achieve positive biodiversity outcomes through improved urban design and infrastructure development. BSUD includes principles to [...]
Rangewide occupancy of a flagship species, the California Gnatcatcher (Polioptila californica) in southern California: habitat associations and recovery from wildfire
Published: 2024-02-12
Subjects: Biodiversity
The California Gnatcatcher (Polioptila californica), a federally threatened species, is a flagship species for regional conservation planning in southern California (USA). An inhabitant of coastal sage scrub vegetation, the gnatcatcher has declined in response to habitat loss and fragmentation, exacerbated by catastrophic wildfires. We documented the status of gnatcatchers throughout their [...]

Benthic macroinvertebrates are a frequently used indicator group for biomonitoring and biological assessment of river ecosystems. However, their taxonomic identification is laborious and requires special expertise. In this study, we aimed to assess the capability of a vision transformer (ViT) model for family-level identification of mayflies (order Ephemeroptera). Specifically, we focused on [...]
Survival patterns and population stability of cliff plants suggest high resistance to environmental variability
Published: 2024-02-09
Subjects: Biodiversity, Ecology and Evolutionary Biology
Cliffs are marginal and poorly studied habitats that are home to a high proportion of endemic or threatened species. Here, we review the survival patterns and population dynamics of plants growing on vertical cliffs and compare them to other plants with similar life histories that grow on the ground. To this end, we have compiled studies of cliff and ground plants from two main sources: MONITO [...]
The costs and benefits of publicising species discoveries.
Published: 2024-02-09
Subjects: Applied Mathematics, Biodiversity, Biology
Public information about where species are found can influence what happens to them – from building support to protect their habitat, to telling poachers where to find a target. Recent heated scientific debate about whether to release information about species’ locations when new species or populations are found have highlighted the trade-off between the risk of damage or loss versus the benefits [...]
Leveraging Biodiversity Net Gain to address invertebrate declines in England
Published: 2024-02-09
Subjects: Biodiversity, Entomology
Meeting ambitions such as the Global Biodiversity Framework 2030 targets will require multiple conservation mechanisms that benefit the widest possible range of habitats and species. Using England as a case study, here we evaluate the likely impact of a novel and ambitious ecological compensation policy, Biodiversity Net Gain (BNG), on terrestrial insects, spiders, and other arthropods [...]
