Fitness consequences and ancestry loss in the Apennine brown bear after a simulated genetic rescue intervention

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Reduction in population size, with its predicted effects on population fitness, is the most alarming anthropogenic impact on endangered species. By introducing compatible individuals, genetic rescue (GR) is a promising but debated approach for reducing the genetic load unmasked by inbreeding and for restoring the fitness of declining ...

Modeling minimum viable population size with multiple genetic problems of small populations

Conservation Biology, Volume 36, Issue 5, October 2022., 2022
Abstract An important goal for conservation is to define minimum viable population (MVP) sizes for long‐term persistence of a species. There is increasing evidence of the role of genetics in population extinction; thus, conservation practitioners are starting to consider the effects of deleterious mutations (DM), in particular the effects of inbreeding

Multiple compensatory mutations contribute to the de‐domestication of Iberian weedy rice

PLANTS, PEOPLE, PLANET, Volume 4, Issue 5, Page 499-510, September 2022., 2022
Weedy plants are a major constraint on agricultural productivity. Weedy rice, a weedy type of rice, invades rice fields worldwide and is responsible for reductions in rice yields. Studies to date have detected multiple independent weedy rice origins in different parts of the world.

Genomic erosion in a demographically recovered bird species during conservation rescue

Conservation Biology, Volume 36, Issue 4, August 2022., 2022
Abstract The pink pigeon (Nesoenas mayeri) is an endemic species of Mauritius that has made a remarkable recovery after a severe population bottleneck in the 1970s to early 1990s. Prior to this bottleneck, an ex situ population was established from which captive‐bred individuals were released into free‐living subpopulations to increase population size ...

Remunicipalisation, Mutating Neoliberalism, and the Conjuncture

Antipode, Volume 54, Issue 1, Page 197-217, January 2022., 2022
Abstract There is a growing interest in the progressive potential of remunicipalisation, a global trend for towns, cities, and even subnational regions to take formerly privatised assets and services back into public ownership. In this paper, we offer a novel conceptualisation of remunicipalisation, developing a spatialised conjunctural perspective ...

Individual‐based simulations of genome evolution with ancestry: The GenomeAdmixR R package

Methods in Ecology and Evolution, Volume 12, Issue 8, Page 1346-1357, August 2021., 2021
Abstract Hybridization between populations or species results in a mosaic of the two parental genomes. This and other types of genome admixture have received increasing attention for their implications in speciation, human evolution, Evolve and Resequence (E&R) and genetic mapping.

Surveillance for pancreatic cancer in high‐risk individuals

BJS Open, Volume 3, Issue 5, Page 656-665, October 2019., 2019
During surveillance of high‐risk individuals for pancreatic cancer, a high proportion (45 per cent) of these individuals who undergo surgical resection for screening‐detected pancreatic lesions have high‐risk neoplastic lesions or pancreatic cancer. Survival was best, and similar, in high‐risk individuals with low‐risk neoplastic lesions and those with
