Hybridization, introgression, and reciprocal gene flow during speciation, specifically the generation of mitonuclear discordance, are increasingly observed as parts of the speciation process. Genomic approaches provide insight into where, when, and how adaptation operates during and after speciation and can measure historical and modern introgression. Whether adaptive or neutral in origin, hybridization can cause mitonuclear discordance by placing the mitochondrial genome of one species (or population) in the nuclear background of another species. The latter,...
Antarctic krill (Euphausia superba) are amongst the most abundant animals on Earth, with a circumpolar distribution in the Southern Ocean. Genetic and genomic studies have failed to detect any population structure for the species, suggesting a single panmictic population. However, the hyper-abundance of krill slows the rate of genetic differentiation, masking potential underlying structure. Here we use high-throughput sequencing of bacterial 16S rRNA genes to show that krill bacterial epibiont communities exhibit spatial structuring, driven...
This is the global dataset used for the Campbell et al. (2021) paper “Testing Bergmann’s Rule in marine copepods”. The dataset includes the mean length of copepods weighted by abundance found in 97,830 continuous plankton recorder (CPR) samples. Further, it contains satellite observations for sea surface temperature, chlorophyll-a, and dissolved oxygen (see paper for details). It was a massive collaborative effort to get this dataset assembled by the Global Alliance of CPR Surveys (GACS 2011,...
Supplementary feeding of wildlife is widespread, being undertaken by more than half of households in many countries. However, the impact that these supplemental resources have is unclear, with impacts assumed to be restricted to urban ecosystems. We reveal the pervasiveness of supplementary foodstuffs in the diet of a wild bird using metabarcoding of blue tit (Cyanistes caeruleus) faeces collected in early spring from a 220km transect in Scotland with a large urbanisation gradient. Supplementary foodstuffs...
Data from: The history of foot-and-mouth disease virus serotype C: the first known extinct serotype?David Paton, Antonello Di Nardo, Nick Knowles, Jemma Wadsworth, Edviges Pituco, Ottorino Cosivi, Alejandro Rivera, Labib Kassimi, Emiliana Brocchi, Kris De Clercq, Consuelo Carrillo, Francois Maree, Raj Singh, Wilna Vosloo, Min-Kyung Park, Keith Sumption, Anna Ludi & Donald King
Foot-and-mouth disease (FMD) is a highly contagious animal disease caused by an RNA virus subdivided into seven serotypes that are unevenly distributed in Asia, Africa and South America. Despite the challenges of controlling FMD, since 1996 there have been only two outbreaks attributed to serotype C, in Brazil and in Kenya, in 2004. This review describes the historical distribution and origins of serotype C and its disappearance. The serotype was first described in Europe in...
Input-output estimates of nitrogen (N) on cropland are essential for improving N management and better understanding the global N cycle. Here, we compare 13 N budget datasets covering 115 countries and regions over 1961-2015. Though most datasets showed similar spatiotemporal patterns, some annual estimates varied widely among them, resulting in large ranges and uncertainty. In 2010, global medians (in Tg N yr-1) and associated min-max ranges were 73 (64-84) for global harvested crop N; 161...
Comments were presented on an article published in October 2020 in Ecology and Evolution (“Predictive ability of a process-based versus a correlative species distribution model”) by Higgins et al. This analyzed natural distributions of Australian eucalypt and acacia species and assessed the adventive range of selected species outside Australia. Unfortunately, inappropriate variables were used with the example MaxEnt species distribution model of Acacia saligna when applied outside Australia, so that large climatically suitable areas in...
