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. -
Sexual Selection Research on Spiders: Progress and Biases
Biol. Rev.

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. -

ONTOGENETIC CHANGES IN THE SPINNING FIELDS OF NUCTENEA CORNUTA AND NEOSCONA THEISI (ARANEAE, ARANEIDAE) Liuming Yu Div. of Biological Sciences University of Missouri Columbia, Missouri 65211 USA and Jonathan A. Coddington Department of Entomology National Museum of Natural History Smithsonian Institution, Washington, DC 20560 USA ABSTRACT The postembryonie development of spinning organs of Nuctenea cornuta (Clerck) and Neoscona theisi (Walckenaer) (Araneae, Araneidae), was studied with SEM. emphasizing first appearance of, and increase in. spigot and fusule complements. Our results suggest that these species may renew their spinning fields by two distinct methods during their ontogeny: spigots may be merely molted in situ like any other cuticular appendage; and/or spigots in one position are lost and "replaced" by an apparently new spigot in a new position. Some or all of each class of fusule (aciniform and pyrifornf) as well as major and minor ampullate spigots are replaced as well as merely molted. Flagelliform and aggregate spigots seem to be merely molted, never replaced. Evidence for these modes of replacement are the apparently vestigial spinning structures that persist from the previous instar, termed "nubbins" in the case of spigots, and "tartipores" in the case of fusules, as well as patterns in the increase in numbers of fusules and spigots. Spinneret ontogeny confirms Theridiidae and Tetragnathidae as phylogenetically derived taxa relative to Araneidae. INTRODUCTION Previous work on spinnerets has concerned histology (see Kovoor 1987 for a review), morphology (Glatz 1967, 1972, 1973; Mikulska 1966, 1967, 1969; Wasowska 1966, 1967, 1970, 1973; Coddington 1989), and function (Peters 1983. -

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.

Il morso di questo ragno ha provocato, a livello locale, acuto e persistente dolore ed edema della parte colpita, seguiti da parestesia della mano sinistra durata alcune ore. La sintomatologia consequenziale, sia locale che sistemica, si è risolta all’incirca in una settimana. SUMMARY A case of arachnidism produced in a woman by Segestria florentina has been reported from Leverano, a town near Lecce, Salento, South Italy. At a local level, the bite provoked a keen and persistent pain and oedema of the part affected, followed by paresy of the left hand lasting some hours. The consequent symptomatology, both local and systemic, disappeared in about a week. INTRODUCTION In nature all spiders are hunters and use many different and sophisticated strategies, the most effective of them being the production and injection of poison through their chelicerae, used to immobilize and kill their prey. Man is only occasionally bitten, with a derived fear and confusion also among those who must to treat the situation. In Italy a large majority of autochthonous spiders are inoffensive, and usually only a small number of them bite man causing, through its poison, a series of local, rarely systemic, symptoms. -

J ÄGER Forschungsinstitut Senckenberg, Senckenberganlage 25, D60325 Frankfurt am Main, Germany. email: [email protected] ABSTRACT. The palpal claw is evaluated as a taxonomic character for 42 species of the spider family Sparassidae and investigated in 48 other spider families for comparative purposes. A pectinate claw appears to be synapomorphic for all Araneae. Elongated teeth and the egg-sac carrying behaviour of the Heteropodinae seem to represent a synapomorphy for this subfamily, thus results of former systematic analyses are supported. One of the Heteropodinae genera, Sinopoda, displays variable character states. According to ontogenetic patterns, shorter palpal claw teeth and the absence of egg-sac carrying behaviour may be secondarily reduced within this genus. Based on the idea of evolutionary efficiency, a functional correlation between the morphological character (elongated palpal claw teeth) and egg-sac carrying behaviour is hypothesized. The palpal claw with its sub-characters is considered to be of high analytical systematic significance, but may also give important hints for taxonomy and phylogenetics. Results from a zoogeographical approach suggest that the sister-groups of Heteropodinae lineages are to be found in Madagascar and east Africa and that Heteropodinae, as defined in the present sense, represents a polyphyletic group. -
