1. Eco‐evolution on the edge during climate change

Author:
Nadeau, Christopher P.; Urban, Mark C.

genetic drift,   etc   ; biodiversity; climate; climate change; extinction; genetic variation; heritability; mortality; prediction;     Show all 9 Subjects
Abstract:
... We urgently need to predict species responses to climate change to minimize future biodiversity loss and ensure we do not waste limited resources on ineffective conservation strategies. Currently, most predictions of species responses to climate change ignore the potential for evolution. However, evolution can alter species ecological responses, and different aspects of evolution and ecology can i ...

Abstract:
... Novel environmental conditions experienced by introduced species can drive rapid evolution of diverse traits. In turn, rapid evolution, both adaptive and non‐adaptive, can influence population size, growth rate, and other important ecological characteristics of populations. In addition, spatial evolutionary processes that arise from a combination of assortative mating between highly dispersive ind ...

Abstract:
... Burrowing Owls (Athene cunicularia) have a large geographic range spanning both North and South America and resident populations occur on many islands in the eastern Pacific Ocean and the Caribbean Sea. Many owl populations are isolated and disjunct from other populations, but studies on genetic variation within and among populations are limited. We characterized DNA microsatellite variation in po ...

Abstract:
... Plant–plant interactions can promote diversification in harsh environments through (1) natural selection producing divergent adaptations to extreme and varying abiotic conditions in plants that grow in the open, or (2) genetic drift involving little niche differentiation in plants that grow associated with others. We assessed whether alpine plant genera characterized by competitively-excluded or f ...

Abstract:
... Genetic drift, loss of heterozygosity and decrease in genetic variability are consequences of high rates of inbreeding over generations.. High density single nucleotide polymorphisms arrays offered new possibilities to estimate inbreeding coefficients more accurately than those from pedigree records or microsatellites genotypes. In the present study different inbreeding coefficients were estimated ...

We have selected the widely distributed Caesalpinia Group (Leguminosae) to test this hypothesis. We used flow cytometry to estimate the amount of DNA in the haploid genome (C-values) of 40 species of the Caesalpinia Group, ...

The advent of massive parallel sequencing technologies has resulted in an increase of studies based upon complete mitochondrial genome DNA sequences that revisit the taxonomic status within and among species.

Here, we report the genetic diversity of PCV‐2 in China. A total of 74 Chinese PCV‐2 strains sequenced between 1999 and 2017 were studied. Based on the ORF2 and complete genomes, we found that apart from the PCV‐2a, PCV‐2b, and PCV‐2d genotypes, two unstable ...

Abstract:
... Mixotrophic plants combine photosynthesis and heterotrophic nutrition. Recent research suggests mechanisms explaining why mixotrophy is so common in terrestrial ecosystems. First, mixotrophy overcomes nutrient limitation and/or seedling establishment constraints. Second, although genetic drift may push mixotrophs to full heterotrophy, the role of photosynthesis in reproduction stabilizes mixotroph ...

BACKGROUND: We tested the premise that optimum-contribution selection with pedigree relationships to control inbreeding (POCS) realises at least as much true genetic gain as optimum-contribution selection with genomic relationships (GOCS) at the same rate of true inbreeding. METHODS: We used stochastic simulation to estimate rates of true genetic gain realised by POCS and GOCS at a 0.01 rate of tr ...
