AbstractThe genetic diversity and population structure of a population of African lions in Hwange National Park, Zimbabwe, was studied using 17 microsatellite loci. [] Key Result Spatial genetic analysis using Bayesian methods suggested a weak genetic structure within the population and high levels of gene flow across the study area. We were able to identify a few individuals with aberrant or admixed ancestry, which we interpreted as either immigrants or as descendants thereof.

Spatiotemporal Genetic Diversity of Lions

The genetic architecture of both historical and modern lions is determined to identify changes in genetic diversity that occurred during this period of landscape and anthropogenic change in Africa.

Spatiotemporal Genetic Diversity of Lions Reveals the Influence of Habitat Fragmentation across Africa

The genetic architecture of both historical and modern lions is determined to document changes in genetic diversity over the last century and provides evidence for male-mediated gene flow and recent isolation of local subpopulations, likely due to habitat fragmentation.

Genetic insights into dispersal distance and disperser fitness of African lions (Panthera leo) from the latitudinal extremes of the Kruger National Park, South Africa

Large genetic differences between the two sampling localities, and low relatedness among males and high dispersal rates among females in the south, are suggestive of unstable territory structure and high pride turnover, have potential implications for spread of diseases and the management of the Kruger lion population.

Ecology rather than people restrict gene flow in Okavango‐Kalahari lions

Reduced gene exchange between animal populations may be an indicator of the effects of anthropogenic fragmentation or it may reflect natural gradients in the landscape that can also result in

Genetic diversity and population structure of small yellow croaker (Larimichthys polyactis) in the Yellow and East China seas based on microsatellites

The results suggest that, despite low genetic differentiation in this species, the small yellow croaker forms a single panmictic population with high genetic variation and gene flow in the studied area.

The Decline in the Lion Population in Africa and Possible Mitigation Measures

The African lion Panthera leo is under threat. Over the last century the lion has lost about 82 % of its former distribution range, and recent estimates suggest that there are 23,000–38,000

Development of Lion MiniSTRs for Use with Modern and Historical DNA Samples

MiniSTRs (<150 bp) with primers designed to be closer to the target region and specific to the lion were developed, and Lion specific STRs were successfully designed for 14 of 17 commonly used microsatellites.

Age‐specific, population‐level pedigree of wild black bears provides insights into reproduction, paternity, and maternal effects on offspring apparent survival

Abstract Wildlife pedigrees provide insights into ecological and evolutionary processes. DNA obtained from noninvasively collected hair is often used to determine individual identities for pedigrees

Where have all the lions gone? Establishing realistic baselines to assess decline and recovery of African lions

Predict empirically the current and recent historical (c1970) landscape connectivity and population size of the African lion as a baseline against which to assess conservation of the species.



Genetic structure is influenced by landscape features: empirical evidence from a roe deer population

The analysis suggests that the landscape has a significant influence on the structuring of the population under study, and illustrates the use of geneland as a powerful method to infer population structure, even in situations of young populations exhibiting low genetic differentiation.

Low gene flow but high genetic diversity in the threatened Mallorcan midwife toad Alytes muletensis

Fine‐scale genetic structuring in the rare and vulnerable Mallorcan midwife toad Alytes muletensis is investigated using eight polymorphic microsatellite markers and tadpoles from 14 pools covering 10 natural sites and two reintroduction sites were sampled.

Ancestral polymorphisms in genetic markers obscure detection of evolutionarily distinct populations in the endangered Florida grasshopper sparrow (Ammodramus savannarum floridanus)

It is argued that despite the lack of phylogenetic distinctiveness of floridanus genotypes the observed genetic differentiation and previously documented phenotypic differences justify continued designation of this subspecies as a protected population segment.

Genetic perspectives on “Lion Conservation Units” in Eastern and Southern Africa

Current understanding of genetic variation in lions (Panthera leo) is inadequate to guide many management decisions necessary for conservation of the species. We studied sequence variation in the

Landscape connectivity influences gene flow in a roe deer population inhabiting a fragmented landscape: an individual–based approach

It is suggested that in a fragmented woodland area roe deer dispersal is strongly linked to wooded structures and hence that gene flow within the roe Deer population is influenced by the connectivity of the landscape.

Rescue of a severely bottlenecked wolf (Canis lupus) population by a single immigrant

It is shown here that the genetic diversity of the severely bottlenecked and geographically isolated Scandinavian population of grey wolves (Canis lupus), founded by only two individuals, was recovered by the arrival of a single immigrant.

Consequences of unequal population size, asymmetric gene flow and sex‐biased dispersal on population structure in brook charr (Salvelinus fontinalis)

The results demonstrate how dispersal and population structure may interrelate to produce spatial variation in intraspecific diversity, and are therefore relevant for conservation programmes seeking to define conservation units or predict recolonization rates of extirpated populations.

Correlation between Fitness and Genetic Diversity

Concerns that the loss of heterozygosity has a deleterious effect on population fitness are strengthened and the IUCN designation of genetic diversity as worthy of conservation is supported.

Genetic structure of lions (Panthera leo L.) in the Selous Game Reserve: implications for the evolution of sociality

Although individual prides were genetically distinct, there was an important genetic structure above the level of social groups, and some neighbouring prides grouped together both geographically and genetically, forming 'superprides' in the population.
