Habitat Association Predicts Genetic Diversity and Population Divergence in Amazonian Birds
American Naturalist, 2017 The ecological traits of organisms may predict their genetic diversity and population genetic structure and mediate the action of evolutionary processes important for speciation and adaptation.

Plant-Parasitic Nematode Genera Associated with Turfgrass in Maryland Golf Courses and Athletic Fields [PDF]
The Plant Pathology JournalField surveys were conducted to assess the occurrence and diversity of plant-parasitic nematodes (PPNs) in golf courses and athletic fields across Maryland, USA, during 2022 and 2023.

Genetic diversity of porcine sapoviruses
Veterinary Microbiology, 2007 Sapoviruses (SaVs) within the Caliciviridae family are an important cause of gastroenteritis in both humans and animals. Although the widespread occurrence of divergent human SaV strains has been reported, there have only been a few studies of porcine SaVs examining their genetic diversity.

Genetic and Memetic Algorithm with Diversity Equilibrium based on Greedy Diversification [PDF]
arXiv, 2017 The lack of diversity in a genetic algorithm's population may lead to a bad performance of the genetic operators since there is not an equilibrium between exploration and exploitation. In those cases, genetic algorithms present a fast and unsuitable convergence.

Genomic and Genetic Diversity within the Pseudomonas fluorescens Complex
PLoS ONE, 2016 The Pseudomonas fluorescens complex includes Pseudomonas strains that have been taxonomically assigned to more than fifty different species, many of which have been described as plant growth-promoting rhizobacteria (PGPR) with potential applications in ...

Population genetic consequences of the Allee effect and the role of offspring-number variation [PDF]
arXiv, 2013 A strong demographic Allee effect in which the expected population growth rate is negative below a certain critical population size can cause high extinction probabilities in small introduced populations. However, many species are repeatedly introduced to the same location and eventually one population may overcome the Allee effect by chance.

Individual-Level SNP Diversity and Similarity Profiles [PDF]
arXiv, 2019 Classic concepts of genetic (gene) diversity (heterozygosity) such as Nei (1973: PNAS) and Nei and Li (1979: PNAS) nucleotide diversity were defined within the context of populations. Although variations are often measured in population context, the basic carriers of variation are individuals.
