Biodiversity Data Journal 9: e69924. https://doi.org/10.3897/BDJ.9.e69924 Abstract Background Long-term monitoring of invertebrate communities is needed to understand the impact of key biodiversity erosion drivers (e.g. habitat fragmentation and degradation, invasive species, pollution, climatic changes) on the biodiversity of these high diverse organisms. The data we present are part of the long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) that started in 2012, aiming to understand the impact of biodiversity erosion drivers on Azorean native forests (Azores, Macaronesia, Portugal). In this contribution, the design of the project, its objectives and the first available data for the spider fauna of two Islands (Pico and Terceira) are described. -

5th Symposium Conference Volume for Research in Protected Areas pages 389 - 398 10 to 12 June 2013, Mittersill Natural Hazards – Hazards for Nature? Avalanches as a promotor of biodiversity. A case study on the invertebrate fauna in the Gesäuse National Park (Styria, Austria) Christian Komposch, Thomas Frieß & Daniel Kreiner Abstract Avalanches are feared by humans and considered “catastrophic” due to their unpredictable and destructive force. But this anthropocentric perspective fails to capture the potential ecological value of these natural disturbances. The Gesäuse National Park is a model-region for investigations of such highly dynamic events because of its distinct relief and extreme weather conditions. This project aims to record and analyse the animal assemblages in these highly dynamic habitats as well as document succession and population structure. 1) Dynamic processes lead to one of the very few permanent and natural vegetationless habitat types in Central Europe outside the alpine zone – i. e. screes and other rocky habitats at various successional stages. In addition to the tight mosaic distribution of a variety of habitats over larger areas, avalanche tracks also offer valuable structures like dead wood and rocks. Remarkable is the sympatric occurrence of the three harvestmen species Trogulus tricarinatus, T. nepaeformis und T. tingiformis, a species diversity peak of spiders, true-bugs and ants; and the newly recorded occurrence of Formica truncorum. 2) The presence of highly adapted species and coenoses reflect the extreme environmental conditions, specific vegetation cover and microclimate of these habitats. Several of the recorded taxa are rare, endangered and endemic. The very rare dwarf spider Trichoncus hackmani is a new record for Styria and the stenotopic and critically endangered wolf-spider Acantholycosa lignaria is dependent on lying dead wood. -

Taxonomic Notes on Agroeca (Araneae, Liocranidae)
Arachnol. Mitt. 37: 27-30 Nürnberg, Juli 2009 Taxonomic notes on Agroeca (Araneae, Liocranidae) Torbjörn Kronestedt Abstract: Agroeca gaunitzi Tullgren, 1952 is stated here to be a junior synonym of A. proxima (O. P.-Cambridge, 1871). The illustrations of the male palp attributed to A. proxima in papers by Tullgren of 1946 and 1952 in fact show A. inopina O. P.-Cambridge, 1886. The record of A. inopina from Finland, quite outside its known distribution range, was based on a misidentification. It is argued that the type species of the genus Agroeca Westring, 1861 should be A. proxima (O. P.-Cambridge, 1871), not A. brunnea (Blackwall, 1833) as currently applied. Protagroeca Lohmander, 1944 is placed as an objective synonym of Agroeca Westring, 1861. Key words: Agroeca gaunitzi, synonyms, type species On the identity of Agroeca gaunitzi Tullgren, 1952 Because Agroeca gaunitzi still appears as a valid Agroeca gaunitzi was described based on a single nominal species (HELSDINGEN 2009, PLATNICK male from the southern part of Swedish Lapland 2009), a re-study of the holotype was undertaken in (TULLGREN 1952).

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.
