Population genetic patterns of species at their range margin have important implications for species conservation. We performed allozyme electrophoresis of 19 loci to investigate patterns of the genetic structure of 17 populations (538 individuals) of the butterfly Polyommatus coridon, a monophagous habitat specialist with a patchy distribution. The butterfly and its larval food plant Hippocrepis comosa reach their northern distribution margin in the study region (southern Lower Saxony, Germany… 

Genetic diversity and population structure of the endangered insect species Carabus variolosus in its western distribution range: Implications for conservation

High FST values and genetic distance measures confirm a very low dispersal power of this habitat specialist of headwater areas and swamps in woodlands, even in comparison with other flightless beetles.

Effects of habitat fragmentation on the genetic diversity and differentiation of Dendrolimus punctatus (Lepidoptera: Lasiocampidae) in Thousand Island Lake, China, based on mitochondrial COI gene sequences

Habitat fragmentation reduced the biological genetic diversity of D. punctatus populations in TIL to some extent, further demonstrating the importance of habitat continuity in biodiversity protection.

Comparative population genetics of mimetic Heliconius butterflies in an endangered habitat; Brazil's Atlantic Forest

Genetic diversity and differentiation among populations of two Heliconius butterfly species in the northern portion of Brazil's Atlantic Forest are examined to estimate the potential impact of habitat fragmentation on population connectivity in butterflies with home-range behavior and lend support to the observation that fine-scale population genetic structure may be common inHeliconius.

Effects of fragmentation and anthropic pressure on the genetic structure of Canthon (Peltecanthon) staigi (Coleoptera: Scarabaeidae) populations in the Atlantic Forest domain

The recent habitat fragmentation may not have led to genetic differentiation, but rather the environmental modifications caused by anthropic pressure seem to be strongly related to the loss of genetic diversity in the species C. (P.) staigi.

Population structure of a large blue butterfly and its specialist parasitoid in a fragmented landscape

The hypothesis that Neotypus parasitoid wasps are more sensitive to habitat fragmentation than their Maculinea butterfly hosts is supported.

Effect of Climatic Conditions and Land Cover on Genetic Structure and Diversity of Eunica tatila (Lepidoptera) in the Yucatan Peninsula, Mexico

This paper represents one of the few studies on population genetics of tropical butterfly in a fragmented landscape and is an important step in understanding the impact of habitat fragmentation on the risk of a butterflies’ decline.

The genetic consequences of different dispersal behaviours in Lycaenid butterfly species

It is deduced that highly fragmented populations do not necessarily have a high extinction probability, but this risk depending much more on specific population genetic structures.

Genetic Variation of Fish Parasite Populations in Historically Connected Habitats: Undetected Habitat Fragmentation Effect on Populations of the Nematode Procamallanus fulvidraconis in the Catfish Pelteobagrus fulvidraco

Results suggest that habitat fragmentation did not cause genetic differentiation among populations or a reduction of diversity in isolated populations of P. fulvidraconis, and at least 2 factors may increase the dispersal range of the nematode, i.e., flash flooding in summer and other species of fish that may serve as the definitive hosts.

The impact of habitat fragmentation on trophic interactions of the monophagous butterfly Polyommatus coridon

It is concluded that the highly specialized butterfly species is more affected by habitat fragmentation than its larval food plant because of its higher trophic position, and conservation efforts should focus first on the most specialized species of interaction networks and second on higher Trophic levels.



Landscape scale genetic effects of habitat fragmentation on a high gene flow species: Speyeria idalia (Nymphalidae)

Comparing levels of genetic differentiation and diversity among populations found in relatively continuous habitat to populations in both recently and historically isolated habitat suggests microsatellite markers can be used to detect the effects of recent habitat fragmentation in natural populations, even at a large geographical scale in high gene flow species.

Influence of landscape on the population genetic structure of the alpine butterfly Parnassius smintheus (Papilionidae)

Rises in the tree‐line in alpine areas, caused by global warming, will lead to reduced gene flow among populations of P. smintheus, suggesting a significant effect of landscape on population genetic structure beyond that of simple isolation by distance.

Population genetic structure of the butterfly Melitaea didyma (Nymphalidae) along a northern distribution range border

The population genetic structure of the butterfly Melitaea didyma was studied along the northern distribution range border in Central Germany by means of allozyme electrophoresis, indicating that the hierarchical structure, at the provincial level, may be breaking down due to isolation of regional populations.

Conservation genetics of peripheral populations of the mygalomorph spider Atypus affinis (Atypidae) in northern Europe

The level of successful dispersal is low, and that the species has not recently reinvaded northern Europe but prevailed undiscovered for several decades, it is concluded that the genetic scenario found for A. affinis might represent that for a wide range of other arthropods with similar life history characteristics.

Postglacial distribution area expansion of Polyommatus coridon (Lepidoptera: Lycaenidae) from its Ponto-Mediterranean glacial refugium

The genetic population structure of Polyommatus coridon was studied by means of allozyme electrophoresis in north-eastern Germany, the Czech Republic, Slovakia and Hungary to suggest the loss of alleles during the postglacial colonisation of eastern Central Europe from an ice-age refugium in the Balkans.

Recent habitat fragmentation caused by major roads leads to reduction of gene flow and loss of genetic variability in ground beetles

Findings strongly support the hypothesis that large roads are absolute barriers to gene flow in C. violaceus, which may lead to a loss of genetic variability in fragmented populations.

Postglacial colonisation of western Central Europe by Polyommatus coridon (Poda 1761) (Lepidoptera: Lycaenidae): evidence from population genetics

The genetic population structure of Polyommatus coridon over large regions of France, Italy and Germany was studied by allozyme electrophoresis and it was found that populations from southern Germany were genetically uniform, well differentiated from French populations and showed a significant loss of genetic diversity.

Lack of genetic differentiation among widely spaced subpopulations of a butterfly with home range behaviour

Examining seven geographically separate subpopulations of Heliconius charithonia in Miami–Dade County, Florida, for genetic differentiation using cellulose acetate electrophoresis provides evidence that the current extensive degree of habitat fragmentation surrounding the city of Miami does not limit gene flow among urban sub Populations.

Limitations to the inference of gene flow at regional geographic scales—an example from the Pieris napi group (Lepidoptera: Pieridae) in Europe

We used hierarchical and pairwise F-statistics to describe genetic differentiation and infer gene flow (M) on local and regional scales within and among parapatric European butterfly taxa in the
