Scale-dependent diversity patterns. affect spider assemblages of two contrasting forest ecosystems
No full textSpiders are important generalist predators in forests. However, differences in assemblage structure and diversity can have consequences for their functional impact. Such differences are particularly evident across latitudes, and their analysis can help to generate a better understanding of region-specific characteristics of predator assemblages. Here, we analyse the relationships between species richness, family richness and functional diversity (FD) as well as alpha- and beta-components of epigeic spider diversity in semi-natural temperate and subtropical forest sites. As expected, within-plot and overall spider species and family richness were higher in the subtropical plots. In contrast, local FD within plots was similar between sites, and differences in FD only became evident at larger spatial scales due to higher species turnover in the subtropical forests. Our study indicates that the functional effects of predator assemblages can change across spatial scales. We discuss how differences in richness and functional diversity between contrasting forest ecosystems can depend on environmental heterogeneity and the effects of species filters acting at local scales. The high turnover observed in the species-rich subtropical forests also requires a more regional perspective for the conservation of the overall diversity and the ecological functions of predators than in less diverse forests, as strategies need to account for the large spatial heterogeneity among plots.

Chalarus
No full textChalarus sp. near zyginae Chalarus perplexus sensu De Meyer et al. (2000) Annotations: The sole representative of the genus on the Canary Islands is morphologically closest to C. zyginae in the female sex, but specimens are slightly larger in size and their frons is not as strongly narrowed (at narrowest point ~ 1.5 times largest frontal facet instead of 1.0). Males should be addressed as C. holosericeus agg., with php being slightly shorter than mtdp (Fig. 11). At this stage, no final decision can be made as to whether Canary Chalarus should be regarded as a distinct species or not, due to the lack of molecular data. For the time being it might be addressed as Chalarus sp. near zyginae.Published as part of Kehlmaier, Christian & Assmann, Thorsten, 2008, The European species of Chalarus Walker, 1834 revisited (Diptera: Pipunculidae), pp. 1-39 in Zootaxa 1936 on page 28, DOI: 10.5281/zenodo.18495
Chalarus exiguus Haliday 1833
No full textChalarus exiguus (Haliday, 1833) Pipunculus exiguus Haliday, 1833: 162 Chalarus konishii Morakote, in Morakote & Hirashima, 1990: 169. Synonymy: Jervis (1992: 290). Diagnosis: Males could not be recorded in this study. See Jervis (1992) for a characterisation. Female with frontal facets greatly enlarged (J 92 Fig. 2 B); frons very narrow, at narrowest point 1.0 times diameter of largest frontal facet; flagellum dark brown; legs dark brown but base of femora and area around femoral-tibial joints may be somewhat paler; pulvilli of all legs of same size, shorter than distitarsus; hairs on femora dark brown but pvsr of mid femur light brown; hairs on thorax and abdomen dark brown; hind femur with apical hairs of pdsr extending as far as apex; abdominal tergites dark brown; ovipositor as in Figs 53 & 56. See Table 1 for coxI and ITS 2 barcode sequence accession numbers. Annotations: The taxon was originally described from the female holotype. No male specimens could be associated with the two females sequenced in this study, but following Jervis (1992), who reared males and females from Alnetoidia alneti taken on the same day and locality, adult males are morphologically indistinguishable from C. holosericeus. However, Jervis (1992) distinguishes males of C. exiguus and C. holosericeus on the basis of pupal characters.Published as part of Kehlmaier, Christian & Assmann, Thorsten, 2008, The European species of Chalarus Walker, 1834 revisited (Diptera: Pipunculidae), pp. 1-39 in Zootaxa 1936 on page 21, DOI: 10.5281/zenodo.18495
Chalarus leticiae Kehlmaier 2003
No full textChalarus leticiae Kehlmaier, 2003 Chalarus leticiae Kehlmaier, 2003: 92. Diagnosis: Male unknown. Female with frontal facets greatly enlarged (Fig. 77); frons at narrowest slightly less than 2.0 times diameter of largest frontal facet; flagellum dark brown; leg dark brown but base of femur, area around femoral-tibial joint and tarsi yellowish; pulvilli of front and mid legs twice the length of hind legs and longer than distitarsus; hairs on femora, thorax and abdomen yellow to light brown; abdominal tergites dark brown; ovipositor as in Figs 44 & 46. See Table 1 for ITS 2 barcode sequence accession number. Annotations: The species was described from two females collected in northern Spain. Morphologically, it resembles C. juliae and C. elegantulus, judging from the shape of the ovipositor and other outer morphological features. Host species are unknown.Published as part of Kehlmaier, Christian & Assmann, Thorsten, 2008, The European species of Chalarus Walker, 1834 revisited (Diptera: Pipunculidae), pp. 1-39 in Zootaxa 1936 on page 25, DOI: 10.5281/zenodo.18495
