Biogeography of the Caribbean Cyrtognatha Spiders Klemen Čandek1,6,7, Ingi Agnarsson2,4, Greta J
www.nature.com/scientificreports OPEN Biogeography of the Caribbean Cyrtognatha spiders Klemen Čandek1,6,7, Ingi Agnarsson2,4, Greta J. Binford3 & Matjaž Kuntner 1,4,5,6 Island systems provide excellent arenas to test evolutionary hypotheses pertaining to gene fow and Received: 23 July 2018 diversifcation of dispersal-limited organisms. Here we focus on an orbweaver spider genus Cyrtognatha Accepted: 1 November 2018 (Tetragnathidae) from the Caribbean, with the aims to reconstruct its evolutionary history, examine Published: xx xx xxxx its biogeographic history in the archipelago, and to estimate the timing and route of Caribbean colonization. Specifcally, we test if Cyrtognatha biogeographic history is consistent with an ancient vicariant scenario (the GAARlandia landbridge hypothesis) or overwater dispersal. We reconstructed a species level phylogeny based on one mitochondrial (COI) and one nuclear (28S) marker. We then used this topology to constrain a time-calibrated mtDNA phylogeny, for subsequent biogeographical analyses in BioGeoBEARS of over 100 originally sampled Cyrtognatha individuals, using models with and without a founder event parameter. Our results suggest a radiation of Caribbean Cyrtognatha, containing 11 to 14 species that are exclusively single island endemics. Although biogeographic reconstructions cannot refute a vicariant origin of the Caribbean clade, possibly an artifact of sparse outgroup availability, they indicate timing of colonization that is much too recent for GAARlandia to have played a role. Instead, an overwater colonization to the Caribbean in mid-Miocene better explains the data. From Hispaniola, Cyrtognatha subsequently dispersed to, and diversifed on, the other islands of the Greater, and Lesser Antilles. Within the constraints of our island system and data, a model that omits the founder event parameter from biogeographic analysis is less suitable than the equivalent model with a founder event. -

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. -

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. -
Transcriptome Characterization of the Aptostichus Atomarius Species Complex Nicole L
Garrison et al. BMC Evolutionary Biology (2020) 20:68 https://doi.org/10.1186/s12862-020-01606-7 RESEARCH ARTICLE Open Access Shifting evolutionary sands: transcriptome characterization of the Aptostichus atomarius species complex Nicole L. Garrison1*, Michael S. Brewer2 and Jason E. Bond3 Abstract Background: Mygalomorph spiders represent a diverse, yet understudied lineage for which genomic level data has only recently become accessible through high-throughput genomic and transcriptomic sequencing methods. The Aptostichus atomarius species complex (family Euctenizidae) includes two coastal dune endemic members, each with inland sister species – affording exploration of dune adaptation associated patterns at the transcriptomic level. We apply an RNAseq approach to examine gene family conservation across the species complex and test for patterns of positive selection along branches leading to dune endemic species. Results: An average of ~ 44,000 contigs were assembled for eight spiders representing dune (n = 2), inland (n = 4), and atomarius species complex outgroup taxa (n = 2). Transcriptomes were estimated to be 64% complete on average with 77 spider reference orthologs missing from all taxa. Over 18,000 orthologous gene clusters were identified within the atomarius complex members, > 5000 were detected in all species, and ~ 4700 were shared between species complex members and outgroup Aptostichus species. Gene family analysis with the FUSTr pipeline identified 47 gene families appearing to be under selection in the atomarius ingroup; four of the five top clusters include sequences strongly resembling other arthropod venom peptides. The COATS pipeline identified six gene clusters under positive selection on branches leading to dune species, three of which reflected the preferred species tree. -
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).

Sand pit for Biodiversity at Cep II quarry Researcher: Klára Řehounková Research group: Petr Bogusch, David Boukal, Milan Boukal, Lukáš Čížek, František Grycz, Petr Hesoun, Kamila Lencová, Anna Lepšová, Jan Máca, Pavel Marhoul, Klára Řehounková, Jiří Řehounek, Lenka Schmidtmayerová, Robert Tropek Březen – září 2012 Abstract We compared the effect of restoration status (technical reclamation, spontaneous succession, disturbed succession) on the communities of vascular plants and assemblages of arthropods in CEP II sand pit (T řebo ňsko region, SW part of the Czech Republic) to evaluate their biodiversity and conservation potential. We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits. -
