Thirty nine species of Salticidae from 33 Australian islands are analyzed with respect to their total distribution, dispersal possibilities and relations with the continental fauna.

Copyright 2006 by the International Society for Comparative Psychology Geographic Variation in a Spider’s Ability to Solve a Confinement Problem by Trial and Error Robert R. Jackson, Fiona R. Cross, and Chris M. Carter University of Canterbury, New Zealand Portia is a genus of web-invading araneophagic (spider eating) jumping spiders known from earlier studies to derive aggressive-mimicry signals by using a generate-and-test (trial and error) algorithm. We studied individuals of Portia labiata from two populations (Los Baños and Sagada) in the Philip- pines that have previously been shown to differ in the level to which they rely on trial-and-error deri- vation of signals for prey capture (Los Baños relied on trial and error more strongly than Sagada P . labiata ). Here we investigated P. labiata ’s use of trial and error in a novel situation (a confinement problem: how to escape from an island surrounded by water) that is unlikely to correspond closely to anything the spider would encounter in nature. During Experiment 1, spiders chose between two potential escape tactics (leap or swim), one of which was set at random to fail (brought spider no closer to edge of tray) and the other of which was set for partially succeeding (brought spider closer to edge of tray).

ZooKeys 440: 57–87. doi: 10.3897/zookeys.440.7891 Abstract In order to resolve better the deep relationships among salticid spiders, we compiled and analyzed a mo- lecular dataset of 169 salticid taxa (and 7 outgroups) and 8 gene regions. This dataset adds many new taxa to previous analyses, especially among the non-salticoid salticids, as well as two new genes – wingless and myosin heavy chain. Both of these genes, and especially the better sampled wingless, confirm many of the relationships indicated by other genes.

The family Salticidae (jumping spiders) is the largest family of spiders; it is known throughout the world, and consists of nearly 6,000 described species belonging to 625 genera, holding 13% of all species of spiders (Foelix, 1996; Jackson et al., 2001). Salticids usually show distinct sexual dimorphism in morphology of the adults. As a result, the male-female complementarity remains unclear for many nominal species in this family. This means that more than a few synonymies are likely hidden in the current classification of the family. Furthermore, due to insufficient sampling efforts in tropical and subtropical zones, it is likely that many species are yet to be discovered. The genus Phintella Strand in Bösenberg and Strand (1906) is one of the most speciose genera in the family Salticidae, and is thought to have diversified in the Oriental and Palearctic regions.

  • Marine Iguanas Are Threatened with Extinction - How Can Revealing a Revised Taxonomy Help to Focus Conservation Efforts of These Endemic Island Reptiles?
    Marine iguanas are threatened with extinction - How can revealing a revised taxonomy help to focus conservation efforts of these endemic island reptiles? A GCSE case study from the Galapagos Conservation Trust Marine iguanas clearly offer important insights into evolutionary processes, but environmental changes mean that their long-term survival could be in jeopardy. Genetic studies have shown us that marine iguana populations on different islands are distinct from one another and there is evidence that there are several subspecies. We also know that some of these populations are already extremely small and face significant threats from marine pollution and predation by introduced species. Loss of these distinct populations could damage the marine iguana’s chances of survival in the long-term. The situation is of great concern because marine iguanas occur on the Galápagos archipelago and nowhere else on earth – they have never been successfully kept outside of the islands. It is therefore vital that we monitor and manage these populations, because if they disappear from Galapagos, they are lost forever. - Dr Amy MacLeod Keywords: biodiversity, classification, Carl Linnaeus, taxonomy, phylogenetic classification, variation, environmental, genotype, phenotype, diversity, population, speciation, species, sub-species A RESOURCE BROUGHT TO YOU BY THE GALAPAGOS CONSERVATION TRUST (REGISTERED CHARITY NO. 1043470) GALAPAGOSCONSERVATION.ORG.UK Discovering Galapagos | Genetics, Taxonomy and Marine Iguanas (GCSE) Back to basics: A revision of classification Taxonomy is the science of classification, involving naming and categorising organisms into groups based on their similarities and differences. Carl Linnaeus first formulated the idea of the classification system, making it easier for scientists to study species, understand how they are related and to recognise biodiversity.

    Records of tile Western Australian MusCllm Supplement No. 52: 159-164 (1995). Salticidae (Arachnida: Araneae) of Oriental, Australian and Pacific Regions, XI. A new genus of Astieae from Western Australia Marek Zabka Zaklad Zoologii WSRP, 08-110 Siedlce, Poland Abstract - Megaloastia mainae gen. et sp. nov., an unusuallong-Ieged spider from Western Australia is described and figured. Remarks on morphology, behaviour and evolution of Salticidae are presented. INTRODUCTION Diagnosis In comparison to some other spider families, the A web-building spider. Legs very long, in males representatives of Salticidae are well defined and up to 4.5 centimeters, thin. Genitalia similar to easy to recognize. They have compact body form, some representatives of Astieae, fovea deep and unique eye pattern, short and stout legs, rather wide, chelicerae of plurident pattern. simple genitalia and complex mating behaviour. They are cursorial long-sighted jumpers, hunting Description actively during the day. Salticids may Medium to large salticid.

Thorax with gentle posterior slope, 1982, 1986a 1987; Maddison and Stratton 1988). oval, fovea deep. Abdomen elongate.

Chelicerae robust, inclined anteriorly, with Salticidae may be found on vegetation, open plurident dentition. Maxillae and labium elongate, ground, on/under rocks and stones, on tree trunks, the first twice as long as wide. Sternum wide, with under bark, in leaf litter. Many salticid genera small marginal indentations, its anterior border mimic other arthropods (Elgar 1993), mostly ants, little wider than base of labium.
