The world was our oyster: Records reveal the vast historical extent of European oyster reef ecosystems

Ruth H. Thurstan, Hannah McCormick, Joanne Preston, et al.

Published: 2023-12-08
Subjects: Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology

Anthropogenic activities have impacted marine ecosystems at extraordinary scales. Biogenic reef ecosystems built by the European flat oyster (Ostrea edulis) typically declined prior to scientific monitoring. Collating >1,600 records published over 350 years, we created a highly resolved (10km2) map of historical oyster reef presence across its biogeographic range, including documenting abundant [...]

Ocean ecosystems have been subjected to anthropogenic influences for centuries, but the scale of past ecosystem changes is often unknown. For centuries, the European flat oyster (Ostrea edulis), an ecosystem engineer providing biogenic reef habitats, was a culturally and economically significant source of food and trade. These reef habitats are now functionally extinct, and almost no memory of [...]

Natural selection is less efficient at species range edges

Chloé Schmidt, Jussi Mäkinen, Jean-Philippe Lessard, et al.

Published: 2023-12-06
Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences

Changing species distributions due to global change underscore a pressing need to better understand range limits. However, our knowledge of general determinants of range limits remains poor despite over a century of work. Theoretical models demonstrate that genetic drift should strengthen across environmental gradients. This can limit natural selection to the point where populations can no longer [...]

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

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

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

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.

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

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: 2023-10-15
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: 2023-10-11
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 [...]
