A large scale semi-quantitative biodiversity assessment was conducted in white oak woodlands areas included the Spanish Network of National Parks, as part a project aimed at revealing biogeographic patterns and identify drivers. The COBRA sampling protocol sixteen 1-ha plots across six national parks using nested design. All adult specimens were identified to species level based on morphology. Uncertain delimitations identifications due either limited information diagnostic characters or...
A new species of the spider genus Loxosceles, L. mrazig sp. n., found in Tunisia is described and illustrated. The male bulb shows a high degree morphological similarity to that gaucho from Brazil, but proportions palpal segments general colouration body reveal significant differences between two species. distance analysis sequences mitochondrial gene cox1 reveals specimen genetic (more than 20%). American laeta form sister group Mediterranean representatives (L. rufescens Tunisian specimen).
We conducted an integrative taxonomic study of a radiation Loxosceles spiders endemic to the Canary Islands combining molecular (mtDNA and nDNA) morphological data. This led formal description six new species: mahan sp. nov. Fuerteventura, Lanzarote, adjacent islets; bentejui tazarte both Gran Canaria; guayota tibicena Tenerife; hupalupa La Gomera El Hierro. These species are included in rufescens group, clearly distinguished from L. by conspicuous dark V-mark posteriorly on pars cephalica,...
Understanding the evolutionary history of morphologically cryptic species complexes is difficult, and made even more challenging when geographic distributions have been modified by human-mediated dispersal. This situation common in Mediterranean Basin where, aside from environmental heterogeneity region, protracted human presence has obscured biogeographic processes that shaped current diversity. Loxosceles rufescens (Araneae, Sicariidae) an ideal example: native to Mediterranean, dispersed...
Abstract Aim Our aim was to assess the evolutionary history of spider genus Loxosceles on Canary Islands. We unravelled its present diversity within archipelago, and investigated origin, mode tempo colonization between islands using a phylogenetic framework. Location Islands, Madeira, Iberian Peninsula, North Africa, Mediterranean region, Guinea. Methods conducted extensive sampling across examined relationships among Island representatives with regard species from western Africa Basin. used...
Capsule Diet composition and feeding behaviour of breeding birds differed between areas high low agricultural intensification.
The species Loxosceles rufescens is native to the Mediterranean but considered cosmopolitan because it has been dispersed worldwide. A previous study revealed 11 evolutionary lineages across Mediterranean, grouped into two main clades, without any clear phylogeographic pattern. high genetic diversity within this (p-distances of up 7.8% in some lineages), together with results obtained different delimitation methods (GMYC, TCS) could indicate existence cryptic species. Here we compare...
We report the step-by-step process of developing de novo microsatellite (SSR) loci in two Loxosceles spider species. used reads obtained with next-generation sequencing (Roche 454) to select hundreds potentially-amplifiable SSRs. After testing amplification and cross-amplification, we characterized 18 SSRs, 11 which were polymorphic rufescens (Dufour 1820) seven L. sp. Fuerteventura - Lanzarote. This method is a relatively fast economic procedure for development fast-evolving nuclear markers spiders.
