TLDR
The potential for successful cross‐species transfer appears highest in species with long generation times, mixed or outcrossing breeding systems, and where genome size in the target species is small compared to the source.Abstract:
Molecular ecologists increasingly require 'universal' genetic markers that can easily be transferred between species. The distribution of cross-species transferability of nuclear microsatellite loci is highly uneven across taxa, being greater in animals and highly variable in flowering plants. The potential for successful cross-species transfer appears highest in species with long generation times, mixed or outcrossing breeding systems, and where genome size in the target species is small compared to the source. We discuss the implications of these findings and close with an outlook on potential alternative sources of cross-species transferable markers.read more

Transcriptome sequencing in an ecologically important tree species: assembly, annotation, and marker discovery
TL;DR: This sequencing study of expressed genes from Lodgepole pine, including their assembly and annotation, and their potential for molecular marker development to support population and association genetic studies illustrate the utility of next generation sequencing as a basis for marker development and population genomics in non-model species.

DNA Barcoding of Marine Metazoa
TL;DR: This review focuses on the usual barcode region for metazoans: a approximately 648 base-pair region of the mitochondrial cytochrome c oxidase subunit I (COI) gene.

Wild pedigrees: the way forward.
TL;DR: In outbred diploid populations, the pedigree approach is superior to analyses based on marker-based pairwise estimators of coancestry, and even where only imprecise pedigrees are available it is possible to estimate the consequences of imprecision for the questions of interest.

Meta-analysis reveals lower genetic diversity in overfished populations.
TL;DR: Evidence suggests that overharvest drives the decay of genetic diversity across a wide range of marine fishes, which may lead to a long-term impact of fishing on their evolutionary potential, particularly if abundance remains low and diversity continues to decay.
Journal ArticleDOI
To what extent do microsatellite markers reflect genome-wide genetic diversity in natural populations?
TL;DR: The results imply that variability at microsatellite marker sets typically used in population studies may not accurately reflect the underlying genomic diversity, and researchers should consider using resequencing‐based approaches for assessing genetic diversity when accurate inference is critical, as in many conservation and management contexts.

TL;DR: A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed.

TL;DR: It is argued that many of these modifications emerged passively in response to the long-term population-size reductions that accompanied increases in organism size, and provided novel substrates for the secondary evolution of phenotypic complexity by natural selection.
