Estimating quantitative genetic and phenotypic (co)variances plays a crucial role in investigating key evolutionary ecological phenomena, such as developmental integration, life history tradeoffs, and niche specialization, as well as in describing selection and predicting multivariate evolution in the wild. While most studies assume (co)variances are fixed over short timescales, environmental [...]

Uneven genetic data limits biodiversity assessments in protected areas globally

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 [...]

Datathons: fostering equitability in data reuse in ecology

In the midst of a looming global biodiversity crisis, approaches to rapidly collect, curate, catalog, and integrate biodiversity data at global scales are more important than ever before1. Historically, data collection and reuse have been linked to local access to funding for scientific research and infrastructure, generating blind spots in the distribution of biodiversity data. At the same time, [...]

How does dispersal shape the genetic structure of animal populations in European cities? A simulation approach

Paul Savary, Cécile Tannier, Jean-Christophe Foltête, et al.

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 [...]

Too simple, too complex, or just right? Advantages, challenges and resolutions for indicators of genetic diversity

Sean Hoban, Jessica da Silva, Alice Hughes, et al.

Published: 2023-06-23
Subjects: Ecology and Evolutionary Biology, Environmental Policy, Genetics, Life Sciences

Measuring genetic diversity of wild species using DNA-based data remains resource intensive and time-consuming for nearly all species. Yet, genetic assessments are needed for global conservation commitments including the Convention on Biological Diversity and for governments and managers to evaluate conservation progress and to prioritize species and populations to preserve and recover genetic [...]

Improving species conservation plans under IUCN’s One Plan Approach using quantitative genetic methods

Drew Sauve, Jane Spero, Jessica Steiner, et al.

Subjects: Ecology and Evolutionary Biology, Genetics, Genetics and Genomics, Life Sciences

Human activities are resulting in altered environmental conditions that are impacting the demography and evolution of species globally. If we wish to prevent anthropogenic extinction and extirpation, we need to improve our ability to restore wild populations. Ex situ populations can be an important tool for species conservation. However, it is difficult to prevent deviations from an optimal [...]

Learning from your mistakes: a novel method to predict the response to directional selection

Lisandro Milocco, Isaac Salazar-Ciudad

Published: 2021-09-27
Subjects: Animal Sciences, Computational Biology, Ecology and Evolutionary Biology, Evolution, Genetics, Genetics and Genomics, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology

Predicting how populations respond to selection is a key goal of evolutionary biology. The field of quantitative genetics provides predictions for the response to directional selection through the breeder’s equation. However, differences between the observed responses to selection and those predicted by the breeder’s equation occur. The sources of these errors include omission of traits under [...]

On May 16, 2020, the Center for Academic Research and Training in Anthropogeny organized the symposium “Impact of Infectious Disease on Humans and Our Origins”. The symposium aimed to gather experts on infectious diseases in one place and discuss the interrelationship between different pathogens and humans in an evolutionary context. The talks discussed topics including SARS-CoV-2, dengue and [...]

Maturation in Atlantic salmon (Salmo salar, Salmonidae): a synthesis of ecological, genetic, and molecular processes

Kenyon Mobley, Tutku Aykanat, Yann Czorlich, et al.

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Genetics, Genetics and Genomics, Genomics, Life Sciences, Physiology, Population Biology

Over the past decades, Atlantic salmon (Salmo salar, Salmonidae) has emerged as a model system for sexual maturation research, owing to the high diversity of life history strategies, knowledge of trait genetic architecture, and their high economic value. The aim of this synthesis is to summarize the current state of knowledge concerning maturation in Atlantic salmon, outline knowledge gaps, and [...]

Honey Bee Diversity Is Swayed by Migratory Beekeeping and Trade Despite Conservation Practices: Genetic Evidences for the Impact of Anthropogenic Factors on Population Structure

The intense admixture of honey bee (Apis mellifera L.) populations at a global scale is mostly attributed to the widespread migratory beekeeping practices and replacement of queens and colonies with non-native races or hybrids of different subspecies. These practices are also common in Anatolia and Thrace, but their influence on the genetic make-up of the five native subspecies of honey bees has [...]
