“…Position along the expansion front was a discrete variable, in which the positions of the C. hortensis westerly range edge for the years 1995, 1999, 2001, 2003, 2005, and 2007-2018 were the values ("trap row 2019" was excluded from analyses as no beetles were caught there), 2018 was the range edge, and the greatest distance was between 2018 and 1995 (Völler et al, 2018). For the purpose of analysis, the position along the expansion front was treated as a continuous variable.…”

“…Carabus hortensis Linnaeus, 1758 (Coleoptera, Carabidae) ground beetles were studied from August to September 2018 in the Lüneburger Heide, Lower Saxony, Germany, where the species has expanded its range westward from ancient forests into adjacent forested areas at a constant pace over the last 25 years (Völler et al, 2018).…”

“…To sample individuals from the range edge and from regions farther back in the species' range (i.e., across the expansion front), rows of live pitfall traps (hereafter "trap rows") were installed parallel to the most westerly edge of the species' range, starting from the leading edge of the expansion and spanning across 3 km to the point at which the species was first observed in this area in 1995 (Völler et al, 2018).…”

“…A map of the study site with some trap rows included in our study can be found in Völler et al (2018). Habitat across the sample area consisted of coherent forests of coniferous, broad-leaved, and mixed stands, and there were no clear systematic habitat differences across the expansion front.…”

“…Here, we study sex-specific changes in body size and body condition along an expanding range margin of the flightless ground beetle, Carabus hortensis L., at its western distribution edge in northern Germany. Previous monitoring of this population (Völler et al, 2018) allows us to pinpoint the precise range edge of the species in previous years, meaning that traits of individuals from the center or "core" of the range can be systematically compared to traits of individuals from the range edge. We predict that individuals at the range edge should be larger in body size than those from the "core", if body size is directly related to leg length and associated movement capacity.…”

Species' ranges are dynamic, flexible, and capable of change through range shifts, contractions, and expansions (Andrewartha & Birch, 1954;Sexton et al., 2009). Range shifts can occur as the result of stochastic processes, whereby random individuals at the edge of the species' range (hereafter: range edge) slowly expand the range over time through random movements (Skellam, 1951). Yet, range shifts

There is increasing concern into the decline of insect populations, with corresponding calls for conservation action aimed towards threatened species in particular. However, there is a distinct paucity of knowledge surrounding habitat requirements, microhabitat selection and conservation actions that may be undertaken for the vast majority of invertebrate species. Carabus intricatus (Coleoptera: Carabidae) Linnaeus, 1761 is a threatened ancient woodland specialist in the United Kingdom with a highly restricted distribution and is listed as a section 41 species of principal importance in England. Despite this, no empirical systematic evidence exists for even basic habitat requirements. Here, we used a patch‐occupancy modelling framework to determine occupancy and detection parameters for C. intricatus and a sympatric generalist species, C. problematicus, which is a potential competitor. Our models showed that decayed deadwood availability and leaf litter covering (an indicator of the availability of mature broadleaved trees) leads to higher occupancy of C. intricatus, whereas decayed dead wood availability and slug abundance are primary determinants of overall abundance. Additionally, detection models showed that higher humidity substantially increased activity of C. intricatus. For C. problematicus, ground moss coverage and overall deadwood volume most strongly influenced occupancy and abundance, whereas there were no humidity related influences on activity. The results support our general predictions about the specialist–generalist nature of the two species in the United Kingdom and indicate that key characteristics of old‐growth temperate rain forests, particularly the availability of deadwood and high humidity, are central to the conservation of these charismatic carabids.
