The behavioural costs of overcrowding for gregarious cave-dwelling bats

Jeaneth Magelen V. Respicio, Kier Celestial Dela Cruz, Alice catherine Hughes, et al.

Published: 2023-11-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

1. Bats are known for their gregarious social behaviour, often congregating in caves and underground habitats, where they play a pivotal role in providing various ecosystem services. Studying bat behaviour remains an underexplored aspect of bat ecology and conservation despite its ecological importance. 2. We explore the costs and impacts of overcrowding on bat social behaviour. This study [...]

The dispersal potential of endangered plants versus non-native garden escapees

Ingmar R. Staude

Published: 2023-10-30
Subjects: Biodiversity, Life Sciences, Plant Sciences

Amidst global challenges like climate change, plant dispersal corridors are essential. In human-dominated landscapes, urban and rural green spaces are key dispersal avenues. Non-native plants are known to benefit from these, yet the potential benefits for endangered plants remain unclear. To address this question, I compared dispersal traits of endangered native plants with those of [...]

Patterns and drivers of population trends on individual Breeding Bird Survey routes using spatially explicit models and route-level covariates

Adam C Smith, Veronica Aponte, Marie-Anne R. Hudson, et al.

Published: 2023-10-27
Subjects: Biodiversity, Biostatistics, Ecology and Evolutionary Biology, Environmental Monitoring, Population Biology, Statistical Methodology, Statistical Models

Spatial patterns in population trends, particularly those at finer geographic scales, can help us better understand the factors driving population change in North American birds. The standard trend models for the North American Breeding Bird Survey (BBS) were designed to estimate trends within broad geographic strata, such as countries, Bird Conservation Regions, U.S. states, and Canadian [...]

Uneven genetic data limits biodiversity assessments in protected areas globally

Ivan Paz-Vinas, Amy Vandergast, Chloe Schmidt, et al.

Published: 2023-10-26
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Policy, Genetics, Life Sciences

Increasing the extent of protected areas (PA) through 30x30 and other area-based conservation initiatives can help to achieve global biodiversity conservation goals across all biodiversity levels. However, intraspecific genetic variation, the foundational level of biodiversity, is rarely explicitly considered in PA design or quality performance assessments. Repurposing existing genetic data could [...]

Fifteen years of elasmobranchs trade unveiled by DNA tools: Lessons for enhanced monitoring and conservation actions

Marcela Alvarenga, Ingrid Vasconcellos Bunholi, Gustavo Reis de Brito, et al.

Published: 2023-10-18
Subjects: Biodiversity, Life Sciences

The trade of elasmobranchs (sharks and rays) in Brazil threatens the country's rich endemic biodiversity. The present study explored the use of DNA-based tools to monitor the Brazilian elasmobranch trade, focusing on their role in identifying processed products and supporting conservation efforts. A systematic search of literature was conducted and included 35 peer-reviewed papers published [...]

Multinational evaluation of genetic diversity indicators for the Kunming-Montreal Global Biodiversity Monitoring framework

Alicia Mastretta-Yanes, Jessica da Silva, Catherine E. Grueber, et al.

Published: 2023-10-16
Subjects: Biodiversity, Genetics and Genomics, Life Sciences

In December 2022, the United Nations Convention on Biological Diversity (CBD) adopted the Kunming-Montreal Global Biodiversity Framework, in which 196 Parties, for the first time, committed to report on the status of genetic diversity for all species. To facilitate this reporting, three genetic diversity indicators were developed, two of which focus on the processes contributing to genetic [...]

Towards causal relationships for modelling species distribution

Daniele Da Re, Enrico Tordoni, Jonathan Lenoir, et al.

Published: 2023-10-14
Subjects: Biodiversity, Bioinformatics, Life Sciences, Natural Resources and Conservation, Statistical Models

1. Understanding the processes underlying the distribution of species through space and time is fundamental in several research fields spanning from ecology to spatial epidemiology. Correlative species distribution models (SDMs) involve popular statistical tools to infer species geographical distribution thanks to spatiotemporally explicit observations of species occurrences coupled with a set of [...]

Inferring the evolutionary history of the Sino-Himalayan biodiversity hotspot using Bayesian phylodynamics

Bethany Allen, Timothy Vaughan, Louis du Plessis, et al.

Published: 2023-10-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution

The current status of the Sino-Himalayan region as a biodiversity hotspot, particularly for flora, has often been linked to the uplift of the Sino-Tibetan Plateau and Himalayan and Hengduan Mountains. However, the relationship between the topological development of the region and the onset of diversification is yet to be confirmed. Here, we apply Bayesian phylodynamic methods to a large phylogeny [...]

Paying it forward: Crowdsourcing of taxonomic harmonization and linking of biodiversity identifiers

Brandon Kwee Boon Seah

Published: 2023-10-10
Subjects: Biodiversity

Linking records for the same taxa between different databases is an essential step when working with biodiversity data. However, name-matching alone is error-prone, because of issues such as homonyms (unrelated taxa with the same name) and synonyms (same taxon under different names). Therefore, most projects will require some degree of curation to ensure that taxon identifiers are correctly [...]

Citizen science as a valuable tool for environmental review

Corey T Callaghan

Published: 2023-09-30
Subjects: Biodiversity

Human development and population growth are placing immense pressure on natural ecosystems, necessitating a balance between development and biodiversity preservation. Citizen science may serve as a valuable resource for monitoring biodiversity and informing decision-making processes, but its use has not been investigated within the realm of environmental review. We sought to quantify the extent [...]

The ecomorphological diversity of Amazonian stream fishes is constrained by phylogenetic relationships

Bruno Eleres Soares, Naraiana L. Benone, Rafael P. Leitão, et al.

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)

Mark Alan Hershkovitz

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

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 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

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

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 [...]
