  • Distribution of Spiders in Coastal Grey Dunes

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.

Univerzita Palackého, Přírodovědecká fakulta, Katedra ekologie a životního prostředí, Olomouc, 35 s., v češtině. ABSTRAKT Pavoukovci jsou ekologicky velmi různorodou skupinou, obývají téměř všechny biotopy a často jsou specializovaní na specifický biotop nebo dokonce mikrobiotop. Mezi specifické biotopy patří také kmeny a dutiny stromů, ptačí budky a biotopy ovlivněné hnízděním kormoránů. Ve své dizertační práci jsem se zabýval ekologií společenstev pavouků a sekáčů na těchto specifických biotopech. V první studii jsme se zabývali společenstvy pavouků a sekáčů na kmenech stromů na dvou odlišných biotopech, v lužním lese a v městské zeleni. Zabývali jsme se také jednotlivými společenstvy na kmenech různých druhů stromů a srovnáním tří jednoduchých sběrných metod – upravené padací pasti, lepového a kartonového pásu. Ve druhé studii jsme se zabývali arachnofaunou dutin starých dubů za pomocí dvou sběrných metod (padací past v dutině a nárazová past u otvoru dutiny) na stromech v lužním lese a solitérních stromech na loukách a také srovnáním společenstev v dutinách na živých a odumřelých stromech. Ve třetí studii jsme se zabývali společenstvem pavouků zimujících v ptačích budkách v nížinném lužním lese a vlivem vybraných faktorů prostředí na jejich početnosti. Zabývali jsme se také znovuosídlováním ptačích budek pavouky v průběhu zimy v závislosti na teplotě a vlivem hnízdního materiálu v budce na početnosti a druhové spektrum pavouků.

  • Seasonal Activity of Wolf Spiders (Araneae: Lycosidae) in Coastal Dune Habitats at Akmensrags-Ziemupe Nature Reserve, Latvia

Spider seasonal dynamics have not been studied previously in Latvia. Here we present the first results on seasonal activity of Lycosidae spiders in dune habitats at the coast of Baltic Sea in Latvia. The spiders were collected with modified pitfall traps from April 2 until November 12, 2006. In total, 843 adult spiders of five genera and 15 species and 531 juvenile spiders were collected. High activity periods occurred in spring, summer and autumn, indicated by spider numbers. Specific species were characteristic for each season: Alopecosa cuneata, Pardosa palustris, P. pullata, Trochosa ruricola and T. terricola – for spring; Alopecosa pulverulenta, Pardosa palustris and Xerolycosa miniata – for summer (the last two species were found only in summer) and Alopecosa fabrilis – for autumn and also spring. Males were more active than females. The activity of juveniles was positively correlated with mean air temperature during the observation period, while adults did not show this relationship. Key words: coastal dunes, Lycosidae, phenology, spider species community.

In order to investigate how average typical 27 species react to habitat fragmentation and disturbance, we adopted a multi-species approach to 28 address occupancy patterns of five specialised dune arthropods (butterflies Hipparchia semele, Issoria 29 lathonia; grasshopper Oedipoda caerulescens; spiders Alopecosa fabrilis, Xysticus sabulosus) in 30 recently fragmented coastal dune habitats which are subjected to varying levels and modes of local 31 disturbance, i.e. trampling by cattle or people. 32 Occupancy patterns were assessed during two successive years in 133 grey dune fragments of the 33 Flemish coastal dunes (Belgium, France). By treating species as a random factor in our models, 34 emphasis was placed on generalisations rather than documenting species-specific patterns.
