12 de sept. de 2019 · We repeatedly measured an ex tended phenotype that directly influences an. organism’s prey acquisition, the web stru cture, of wild orb-weaving spiders (Micrathena. vigorsii ), which re-build ...
1 de sept. de 2007 · The genital morphology of Agriognatha species is unique among Tetragnathidae and it provides robust synapomorphic evidence for the monophyly of genus and the phylogenetic implications of these new findings are discussed. The female genital morphology of the spiders in the araneoid genus Agriognatha (Tetragnathidae) is described and illustrated.
16 de feb. de 2015 · Out of the twilight zone: phylogeny and evolutionary morphology of the orb‐weaving spider family Mysmenidae, with a focus on spinneret spigot morphology in symphytognathoids (Araneae, Araneoidea) Lara Lopardo. Corresponding Author.
Composition, resulting statistics, as well as informative character proportions are reported for each data set. Abbreviations: CI, consistency index; MPT, most-parsimonious tree; RI, retention index.
28 de ago. de 2020 · Orb-weaving spiders often build webs with up-down asymmetry; the bottom may be larger than the top (Zschokke & Nakata, 2015). We observed this in our study population; although we did not measure the radius of the web upwards or downwards, our counts of radii were higher downwards (mean = 28.4) than upwards (mean = 25.0).
1 de may. de 2018 · The spider genus Mecynogea comprises nine species distributed predominantly in the Neotropics. Although the genus has been revised recently, several aspects of its taxonomy and morphology are still unresolved. In this paper, Mecynogea infelix (Soares & Camargo, 1948) is removed from the synonymy of Mecynogea bigibba Simon, 1903 and redescribed.
Abstract. We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S, COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 outgroups and 133 araneid ingroups representing the subfamilies Zygiellinae Simon, 1929, Nephilinae Simon, 1894, and the typical araneids, here informally named ...
