The Case for a Science-Based Strategy for Conserving Threatened Butterfly Populations in the UK andSlovak Republics, southern Fennoscandia, the Netherlands, Belgium, northern France, and the UK (see reviews in Beek et al. 1992, Heath 1981, Pullin 1994, Thomas 1991, Warren 1992). Although most of these regions have a poor butterfly fauna compared with central-southern Europe (Dennis & Williams 19

Decline and Rehabilitation of the Apollo Butterfly , (Linnaeus, 1758) in the Pieniny National Park (Glassl 1993). In the northwestern part of its range the species is clearly declining. This process has been observed and recorded in Scandinavia (Bengtsson et al. 1989, Mikkola 1979), and in Central and Eastern Europe from Germany (Glassl 1993) through Bohemia (Novak & Spitzer 1982), Slovakia (Kulfa

Forest Resource Management and the Conservation of Arboreal Marsupials in Central Victoria, Southeasustralia. A major component of this research has included studies of the conservation biology of several species of arboreal marsupials that occur in these forests, particularly the endangered Leadbeater’s possum (. MCCOY, 1867), the more common and widespread greater glider (. (KERR, 1792)), and th

Population size, Genetic Variation, and Related Para-Meters in Small, Isolated Plant Populations: a fragmentation. In one of the review chapters of this book (Oostermeijer et al.: 93-101) the most important of these theories are described, and several references were given to empirical studies demonstrating that these theories are actually valid in the field. In this chapter, a case study is prese

These changes have resulted in alterations to ecosystem processes and biotic impoverishment. In fact, the most critical land degradation prob

Genetical Aspects of Fragmented Plant Populationst cases, this is caused by intensive agricultural practices. The rate of fragmentation of these areas in the landscape has increased, resulting in a patchwork of often small remnants with a high degree of isolation. Inside one patch, not only habitats but also populations are fragmented This can res
