“…Matern et al 2007). These studies have highlighted and further refined which specific requirements determine habitat associations (Matern et al 2007). Key habitat variables governing the occurrence of the adult beetles were found to be: short distance to water, high soil moisture, open woodland vegetation cover, a near-neutral pH of the soil and the lack of ground cover.…”

Population ecology and genetic studies are complementary approaches to address central questions of conservation biology and can provide information for the protection of biodiversity and the improvement of conservation measures which may otherwise be unattainable. This contribution highlights the benefit of combining diverse approaches for obtaining knowledge on a relict species and for implementing suitable conservation measures. We use the example of Carabus variolosus, a flightless European beetle that is listed as a Species of Community Interest in the EU Habitats and Species Directive. Ongoing investigations established the species' habitat choice, population ecology and population genetics, and yield first results from mitochondrial DNA analysis (COI). In small isolated habitat patches we found small sized populations that are genetically strongly differentiated even if adjacent. Evidence for a number of glacial refugia was found. However, all C. v. nodulosus populations studied North of the Alps share the same haplotype. We will discuss our findings in the light of the history of the species, of its taxonomic classification and of their implications for conservation.

“…In particular, relatively immobile invertebrates have been neglected by previous landscape ecology research (Mazerolle and Villard 1999;Bailey 2007). Understanding the impact of habitat fragmentation on this group of species is of particular importance, as many have highly restricted distributions and are considered as priorities for conservation action; they may also be especially vulnerable to fragmentation impacts (Ranius 2002;Buse et al 2007;Matern et al 2007;NBN Gateway 2007). Those investigations undertaken to date have focused primarily on beetles, and have revealed differing responses to fragmentation based on variation in the degree of habitat specialisation (Rukke and Midtgaard 1998;Ranius 2000;Rukke 2000).…”

Manuscript word count: 7291 2 AbstractLittle information is available regarding the landscape ecology of woodland invertebrate species with limited dispersal ability. An investigation was therefore conducted within woodland fragments in an agricultural landscape for the flightless wood cricket (Nemobius sylvestris) on the Isle of Wight, UK. The current pattern of distribution of the species, established during a field survey, was related to measures of habitat availability and habitat isolation/fragmentation. Results revealed that wood cricket populations were patchily distributed and mainly found in relatively large mature woodland fragments situated closely (<50 m) to another occupied site. Although the occurrence of wood cricket was related to fragment area, isolation, habitat availability and woodland age, a logistic regression model revealed that presence of the species was most accurately predicted by fragment isolation and area alone. These results highlight the vulnerability of relatively immobile woodland invertebrate species, such as wood cricket, to the potential negative impacts of habitat fragmentation.Keywords: woodland; forest; habitat availability; fragmentation; landscape scale; invertebrate; insect; wood cricket; Nemobius sylvestris; Isle of Wight. IntroductionIn recent years, many habitats and species have been subjected to increasing anthropogenic pressures. Activities such as agricultural intensification and exploitation of natural resources have resulted in substantial habitat loss and fragmentation (e.g. Forman and Godron 1986;Andrén 1994), which are increasingly being recognised as principal drivers of biodiversity loss worldwide (Hanski 1998;Fahrig 2003). These effects are typically evident at the landscape scale, with many landscapes now being characterised by a mosaic of different agricultural land use types with fragments of native habitat embedded within them (e.g. Peterken 2000; Newton 2007).In fragmented landscapes, the distribution and abundance of species is commonly influenced by the quality and amount of habitat available within individual habitat fragments, and the spatial configuration of fragments within the landscape (Andrén 1994;Fahrig 2003). In terrestrial environments, the factors most commonly examined in relation to patterns of species diversity at the landscape scale are measures of fragment or patch area and connectivity. A substantial body of literature is now available documenting the influence of these factors (Andrén 1994;Mazerolle and Villard 1999;Bennett 1999Bennett , 2003Ewers and Didham 2006;Bailey 2007). Many studies have recorded a positive relationship between species diversity and fragment area and a negative relationship between diversity and the degree of isolation, consistent with island biogeography theory Wilson 1963, 1967). However, these relationships vary in their precise response and degree of significance among and within different taxonomic groups, primarily because of variation in habitat specialisation and the level of permeability of the m...

“…Where little is known about a particular species and even basic knowledge may be scant (as is often the case for species that are either naturally rare or have become rare as a result of human impact in the past) it is vital that the biology and habitat preferences of the species concerned become a subject of study. Only if such information is available can effective conservation measures be developed and implemented (Matern et al 2007). However, ultimately to be successful the implementation of these measures must include the capacity to follow up on the measures, adequate budgets to do so, and supporting government policies.…”

The issues and challenges facing us in ensuring the survival of as many species and ecosystems as possible call for a renewed research focus to address how to improve management strategies and policy making now and into the future. The key issues to be addressed by activities of the International Union of Forest Research Organization's (IUFRO) Task Force on Endangered Species and Nature Conservation include such issues as: (i) preventing species from being listed by maintaining species populations at sufficient levels that they do not require listing; (ii) recovering threatened and endangered species; (iii) developing management practices and strategies; (iv) balancing actions affecting suites of threatened or endangered species; (v) developing conservation strategies for species without definitive taxonomic treatments; (vi) dealing with global change; (vii) dealing with invasive species; and (viii) restoring critical habitats.
