Furthermore, in a study on an endangered longhorn beetle living on dead trees, Buse et al (2007) revealed that variables measured at the tree level were better predictors of presence of the species than spatial measurements between trees. These examples indicate the overall importance of within patch (i.e.…”

“…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...

Statistical evaluation of Ips typographus population density: a useful tool in protected areas and conservation-oriented forestry

Ips typographus (Col., Curculionidae, Scolytinae) occurring on Picea abies stems is a species characterised by large fluctuations in population numbers and causing frequent outbreaks. In protected areas, I. typographus is regarded as a sensitive bioindicator responsive to changes in forest health and vitality. In conservation-oriented forestry, attention is being paid to the ecological value of I. typographus beetles as ecosystem engineers and keystone species, driving forest natural regeneration and conversion. Despite many publications devoted to I. typographus, no accurate method for estimating the population density of this species has been developed. The objective of this study was to develop a statistical method for estimating I. typographus population density that enables calculation of estimation errors. The proposed method consists of two parts: tree-level analyses and stand-level analyses. Part one allows calculation of the total density of I. typographus infestation of each of P. abies selected stem (after selecting sample windfalls), part two allows estimation of the mean total infestation density of the stem in the area investigated. Linear regression functions were applied to part one and survey sampling to part two. The method is only marginally invasive because it involves debarking of one 0.5 m-long stem section on maximum 50 P. abies windfalls (trap trees can optionally be used). The developed method was employed to assess I. typographus population density in the Ś więtokrzyskie Mountains in Central Poland in an area of ca. 4,000 ha. In 2010, in the area investigated, the mean total I. typographus infestation density of the P. abies stem was 440.6 maternal galleries/m 2 (from 358.7 to 522.6 maternal galleries/m 2 with a = 0.05; the relative error of estimation was 18.6%). The examined I. typographus population was in a progradation phase. The proposed method can be used in nature reserves, national parks and managed forests, mainly for scientific purposes.
