TL;DR: Habitat utilization by Lopinga achine (Nymphalidae : Satyrinae) larvage and ovipositing females is studied to propose a new strategy for sustainable development in the arid regions.
TL;DR: In this article, the effects of tree and bush cover on population size were studied experimentally south of Link÷ping, Sweden, where 86% of the sites in southern Sweden occupied by L. achine are unmanaged.
Abstract: 1. Like many butterflies, the woodland brown Lopinga achine has disappeared from many locations in western Europe due to habitat loss. The population dynamics and the effects of tree and bush cover on population size were studied experimentally south of Link÷ping, Sweden. 2. Most populations in the study area were small ( 90%. The population at the sixth site, managed in 1995, decreased by 30%. 4. Cover of the host-plant Carex montana increased significantly at edges of new glades and decreased in closed unaffected woods. Successful restoration probably requires the presence of C. montana along edges of new glades from the onset of management because this plant was slow to colonize plots where it was initially absent. 5. Currently, 86% of the sites in southern Sweden occupied by L. achine are unmanaged. If this situation continues, the metapopulation in this study will probably collapse within 20-40 years. Recovery programmes for L. achine should emphasize metapopulation dynamics, host-plant cover and vegetation dynamics over time. As with many butterflies, successful conservation requires a blend of detailed autoecology and active site management to produce the required successional conditions.
TL;DR: There were few movements between sites, but the majority of the movements were small with mean movements between recaptures of 45–54 m for males and 94–116 m for females.
TL;DR: The distribution of occupied and vacant sites and migration of the threatened butterfly Lopinga achine were studied in the province of Ostergotland, Sweden, and the probability of occupation increased with increasing patch area and decreasing distance to the nearest occupied patch.
TL;DR: In this article, the authors analyzed Lopinga achine habitat preferences on a regional scale in the Bavarian Alps and determined potential drivers of the decline on a national scale across Germany.
