A Checklist of the Non -Acarine Arachnids
Original Research A CHECKLIST OF THE NON -A C A RINE A R A CHNIDS (CHELICER A T A : AR A CHNID A ) OF THE DE HOOP NA TURE RESERVE , WESTERN CA PE PROVINCE , SOUTH AFRIC A Authors: ABSTRACT Charles R. Haddad1 As part of the South African National Survey of Arachnida (SANSA) in conserved areas, arachnids Ansie S. Dippenaar- were collected in the De Hoop Nature Reserve in the Western Cape Province, South Africa. The Schoeman2 survey was carried out between 1999 and 2007, and consisted of five intensive surveys between Affiliations: two and 12 days in duration. Arachnids were sampled in five broad habitat types, namely fynbos, 1Department of Zoology & wetlands, i.e. De Hoop Vlei, Eucalyptus plantations at Potberg and Cupido’s Kraal, coastal dunes Entomology University of near Koppie Alleen and the intertidal zone at Koppie Alleen. A total of 274 species representing the Free State, five orders, 65 families and 191 determined genera were collected, of which spiders (Araneae) South Africa were the dominant taxon (252 spp., 174 genera, 53 families). The most species rich families collected were the Salticidae (32 spp.), Thomisidae (26 spp.), Gnaphosidae (21 spp.), Araneidae (18 2 Biosystematics: spp.), Theridiidae (16 spp.) and Corinnidae (15 spp.).

Sexual Selection Research on Spiders: Progress and Biases
Biol. Rev. (2005), 80, pp. 363–385. f Cambridge Philosophical Society 363 doi:10.1017/S1464793104006700 Printed in the United Kingdom Sexual selection research on spiders: progress and biases Bernhard A. Huber* Zoological Research Institute and Museum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany (Received 7 June 2004; revised 25 November 2004; accepted 29 November 2004) ABSTRACT The renaissance of interest in sexual selection during the last decades has fuelled an extraordinary increase of scientific papers on the subject in spiders. Research has focused both on the process of sexual selection itself, for example on the signals and various modalities involved, and on the patterns, that is the outcome of mate choice and competition depending on certain parameters. Sexual selection has most clearly been demonstrated in cases involving visual and acoustical signals but most spiders are myopic and mute, relying rather on vibrations, chemical and tactile stimuli. This review argues that research has been biased towards modalities that are relatively easily accessible to the human observer. Circumstantial and comparative evidence indicates that sexual selection working via substrate-borne vibrations and tactile as well as chemical stimuli may be common and widespread in spiders. Pattern-oriented research has focused on several phenomena for which spiders offer excellent model objects, like sexual size dimorphism, nuptial feeding, sexual cannibalism, and sperm competition. The accumulating evidence argues for a highly complex set of explanations for seemingly uniform patterns like size dimorphism and sexual cannibalism. Sexual selection appears involved as well as natural selection and mechanisms that are adaptive in other contexts only. Sperm competition has resulted in a plethora of morpho- logical and behavioural adaptations, and simplistic models like those linking reproductive morphology with behaviour and sperm priority patterns in a straightforward way are being replaced by complex models involving an array of parameters. -
Comparison of Reproductive Traits Between Two Salt-Marsh Wolf Spiders (Araneae, Lycosidae) Under Different Habitat Suitability Conditions

L. Ledeganckstraat 35, 9000 Ghent, Belgium 4 University of Antwerp, Evolutionary Ecology Group, Department of Biology, Groenenborgerlaan 171, 2020 Antwerpen, Belgium Abstract Salt-marsh invasions by the grass Elymus athericus (Poaceae) recently transformed usual areas dom- inated by Atriplex portulacoides (Chenopodiaceae) into homogeneous meadows. Two wolf spider species, Pardosa purbeckensis and Arctosa fulvolineata, show contrasting densities and habitat prefer- ences in salt marshes (respectively dominant and co-dominant ground-living spiders) and oppositely respond to the grass invasion. This allowed us to test whether invasive species that alter habitat struc- ture affect reproduction in addition to previously recorded changes in density. Reproductive traits (female mass, cocoon mass, number and volume of eggs, hatched cocoon as a proxy of reproduc- tion date) were studied in both invaded and natural salt marshes during 2007 and 2008 in the Mont St-Michel Bay (France). In both species, reproductive outputs (cocoon mass) were higher in optimal habitats and volume of eggs was found to be independent from female mass, whereas the latter sig- nificantly influenced the number of eggs. -
Abundance and Community Composition of Arboreal Spiders: the Relative Importance of Habitat Structure
AN ABSTRACT OF THE THESIS OF Juraj Halaj for the degree of Doctor of Philosophy in Entomology presented on May 6, 1996. Title: Abundance and Community Composition of Arboreal Spiders: The Relative Importance of Habitat Structure. Prey Availability and Competition. Abstract approved: Redacted for Privacy _ John D. Lattin, Darrell W. Ross This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed the importance of several habitat variables as predictors of spider abundance and diversity on and among individual tree species. The greatest abundance and species richness of spiders per 1-m-long branch tips were found on structurally more complex tree species, including Douglas-fir, Pseudotsuga menziesii (Mirbel) Franco and noble fir, Abies procera Rehder. Spider densities, species richness and diversity positively correlated with the amount of foliage, branch twigs and prey densities on individual tree species. The amount of branch twigs alone explained almost 70% of the variation in the total spider abundance across five tree species. In 1994, I experimentally tested the importance of needle density and branching complexity of Douglas-fir branches on the abundance and community structure of spiders and their potential prey organisms. This was accomplished by either removing needles, by thinning branches or by tying branches. Tying branches resulted in a significant increase in the abundance of spiders and their prey. Densities of spiders and their prey were reduced by removal of needles and thinning. -

Both of his parents, Gleb K. Mikhailov (1929–2021) and Galina R. Mikhailova (1926–2019), were research scientists. Kirill’s father was an expert in the history of mechanics, and mother, a biologist. Since early childhood Kirill was raised mainly by his maternal grandparents, Ro- man P. Nosov and Antonina V. Nosova. Kirill’s grandfather, a CPSU official and a career administrator at the Ministry of Energetics, retired from his post in 1965 to take care of the grandson. Kirill’s grandmother, an obstetrician by profession, received disability at a military plant during the WWII in evacuation, and was a housewife after the war. In 1978, Kirill began his studies at the Division of Biology (Biologicheskii Fakul’tet) of the Moscow State University (below, MSU). Even earlier, as a schoolboy, Kirill used to buy books on zoology, especially separate issues of the Fauna of the USSR and Keys to the Fauna of the USSR, then relatively cheap and available. -

Arctosa binalis Yu & Song, 1988 is a junior synonym of A. depectinata (Bösenberg & Strand, 1906). Males of Arctosa gougu Chen & Song, 1999 and Arctosa vaginalis Yu & Song, 1988 are described for the first time. All specimens examined were collected from the Yunnan Province, China. Morphological illustrations, photos, descriptions and SEM photographs of the male bulbus of all species are given. Stridulatory files on chelicerae in Lycosidae are reported for the first time. Key words: Taxonomy, wolf spiders, morphology, redescription, distribution Introduction The wolf spider genus Arctosa C.L. Koch, 1847 with 171 species (Platnick 2012), is one of the largest genera of Lycosidae. The genus has been relatively well revised in Europe (Lugetti & Tongiorgi 1965), the Nearctic (Dondale and Redner 1983) and Japan (Tanaka 2009). In this genus, 78 species are known from only one sex (16 from males and 62 from females). -
