Ecosystem functions and services provided by dung beetles: a global meta-analysis

Fevziye Hasan, Louis A Schipper, Kiri Joy Wallace, et al.

Published: 2023-12-19
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

Dung beetles are known to carry out a range of ecosystem functions such as secondary seed dispersal, bioturbation, nutrient cycling, plant growth, pest and parasite control, and trophic regulation, many of which support key ecosystem services. Despite the globally purported significance of this group of insects for ecosystem functioning, there has been no quantitative synthesis to establish the [...]

Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

Introducción: Los muestreos directos constituyen la mejor manera de documentar la riqueza biológica de un lugar, pero pueden verse limitados por diversas circunstancias. Nos preguntamos si la riqueza de especies documentada en campo puede ser complementada con datos de plataformas digitales de biodiversidad. Objetivo: Analizar si los datos de ocurrencia de especies disponibles en la Global [...]

Bird species’ centrality in seed-dispersal networks varies within climatic niches

Gabriel M. Moulatlet, Wesley Dáttilo, Daniel Kissling, et al.

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

Understanding how the functional role of species within seed-dispersal networks varies across geographical and climatic gradients can reveal the mechanisms driving network organization. Using data for 157 bird species from all continents, we evaluated the variation of species’ centrality within local networks across species’ climatic niches (occupied climatic conditions) and in response to [...]

A user-friendly AI workflow for customised wildlife-image classification

Barry W. Brook, Jessie C. Buettel, Zach Aandahl

Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology

Monitoring wildlife is crucial for making informed conservation and land-management decisions. Remotely triggered cameras are widely used for this, but the resulting 'big data' are laborious to process. Artificial intelligence (AI) offers a solution to this bottleneck, but it has been challenging for ecologists and practitioners to tailor current approaches to their specific use cases. Generic, [...]

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: 2023-12-07
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 [...]

Historical dataset details the distribution, extent and form of lost Ostrea edulis reef ecosystems.

Subjects: Aquaculture and Fisheries Life Sciences, Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology

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 [...]

Opinion: Missing half the picture, focus on stony corals during bleaching events has left critical knowledge gaps in our understanding of reef-scale bleaching and recovery

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.

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 extensive and inadvertent elasmobranch trade in Brazil detected by DNA tools

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

Subjects: Biodiversity, Life Sciences

The trade of elasmobranchs (sharks and rays) in Brazil raises significant concerns due to the country's rich endemic biodiversity. The present study explores 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 carried out and included 35 [...]

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.

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 [...]

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 [...]
