Distribution of Spiders in Coastal Grey Dunes
kaft_def 7/8/04 11:22 AM Pagina 1 SPATIAL PATTERNS AND EVOLUTIONARY D ISTRIBUTION OF SPIDERS IN COASTAL GREY DUNES Distribution of spiders in coastal grey dunes SPATIAL PATTERNS AND EVOLUTIONARY- ECOLOGICAL IMPORTANCE OF DISPERSAL - ECOLOGICAL IMPORTANCE OF DISPERSAL Dries Bonte Dispersal is crucial in structuring species distribution, population structure and species ranges at large geographical scales or within local patchily distributed populations. The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

However, knowledge about the biodiversity of natural enemies that may be useful as biocontrol agents is scarce. The objectives of this work were: (i) to study the diversity of predaceous arthropods; and (ii) to establish a suitable sampling protocol for arthropods of the almond tree canopy. Between April and October of 2007 and 2008, 25 randomly selected trees were sampled in an organic almond grove located in the north-east of Portugal using the beating technique. The specimens collected were counted and identified and the sampling pro- tocol was established by using the accumulation curves and the seasonal richness peaks of the most abundant groups of natural enemies. A total of 1856 and 1301 arthropods were captured, respectively, in 2007 and 2008, where Araneae, Coccinellidae and Formicidae were the most abundant groups. A total of 14 families and 29 species of spiders were identified as Linyphiidae, Philodromidae, Thomisidae, Araneidae and Oxyopidae, the five most abundant families in both years. -

Vol. 12, No. 2, June 2017__________ 433 ANNOTATED CHECKLIST OF THE SPIDERS OF TURKEY Hakan Demir* and Osman Seyyar* * Niğde University, Faculty of Science and Arts, Department of Biology, TR–51100 Niğde, TURKEY. E-mails: [email protected]; [email protected] [Demir, H. & Seyyar, O. 2017. Annotated checklist of the spiders of Turkey. Munis Entomology & Zoology, 12 (2): 433-469] ABSTRACT: The list provides an annotated checklist of all the spiders from Turkey. A total of 1117 spider species and two subspecies belonging to 52 families have been reported. The list is dominated by members of the families Gnaphosidae (145 species), Salticidae (143 species) and Linyphiidae (128 species) respectively. KEY WORDS: Araneae, Checklist, Turkey, Fauna To date, Turkish researches have been published three checklist of spiders in the country. The first checklist was compiled by Karol (1967) and contains 302 spider species. The second checklist was prepared by Bayram (2002). He revised Karol’s (1967) checklist and reported 520 species from Turkey. Latest checklist of Turkish spiders was published by Topçu et al. (2005) and contains 613 spider records. A lot of work have been done in the last decade about Turkish spiders. So, the checklist of Turkish spiders need to be updated. We updated all checklist and prepare a new checklist using all published the available literatures. This list contains 1117 species of spider species and subspecies belonging to 52 families from Turkey (Table 1). This checklist is compile from literature dealing with the Turkish spider fauna. The aim of this study is to determine an update list of spider in Turkey. -

The females of two species are described for the first time: Nomisia levyi Chatzaki, 2010 and Erigonoplus simplex Millidge, 1979. The earlier suggestion of the synonymy of Pardosa tatarica with Pardosa atomaria is repeated. Theridion betteni Wiehle, 1960 is reported as new for Albania. -
Phantom Spiders 2: More Notes on Dubious Spider Species from Europe
© Arachnologische Gesellschaft e.V. Frankfurt/Main; http://arages.de/ Arachnologische Mitteilungen / Arachnology Letters 52: 50-77 Karlsruhe, September 2016 Phantom spiders 2: More notes on dubious spider species from Europe Rainer Breitling, Tobias Bauer, Michael Schäfer, Eduardo Morano, José A. Barrientos & Theo Blick doi: 10.5431/aramit5209 Abstract. A surprisingly large number of European spider species have never been reliably rediscovered since their first description many decades ago. Most of these are probably synonymous with other species or unidentifiable, due to insufficient descriptions or mis- sing type material. In this second part of a series on this topic, we discuss about 100 of these cases, focusing mainly on species described in the early 20th century by Pelegrín Franganillo Balboa and Gabor von Kolosváry, as well as a number of jumping spiders and various miscellaneous species. In most cases, the species turned out to be unidentifiablenomina dubia, but for some of them new synonymies could be established as follows: Alopecosa accentuata auct., nec (Latreille, 1817) = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa barbipes oreophila Simon, 1937 = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa mariae orientalis (Kolosváry, 1934) = Alopecosa mariae (Dahl, 1908) syn. nov.; Araneus angulatus afolius (Franganillo, 1909) and Araneus angulatus atricolor Simon, 1929 = Araneus angulatus Clerck, 1757 syn. nov.; Araneus angulatus castaneus (Franganillo, 1909) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus angulatus levifolius (Franganillo, 1909), Araneus angulatus niger (Franganillo, 1918) and Araneus angulatus nitidifolius (Franganillo, 1909) = Araneus angulatus Clerck, 1757 syn. nov.; Araneus angulatus pallidus (Franganillo, 1909), Araneus angulatus cru- cinceptus (Franganillo, 1909), Araneus angulatus fuscus (Franganillo, 1909) and Araneus angulatus iberoi (Franganillo, 1909) = Araneus pal- lidus (Olivier, 1789) syn. -

Ehrenwörtliche Erklärung……………………………………….…………114 Declaration This dissertation is the result of my own work and includes nothing that is the outcome of work done in collaboration. Chapter I General Introduction Canopy research and temperate forests Forests, coral reefs and soil contain the majority of the world’s known biodiversity (Connell 1978; Ozanne et al. 2003; Floren and Schmidl 2008), and as much as half of all the macroscopic life forms are believed to dwell in forest canopies, where they remain insufficiently investigated, or undiscovered entirely (Floren and Schmidl 2008). The study of canopy arthropod communities is a relatively young subfield of ecology, and it can be traced back to the study of the extremely diverse flora and fauna of tropical tree canopies in the late 1970s (Perry 1978; Erwin and Scott 1980; Stork and Hammond 1997).
