Forrageamento em Achaearanea cinnabarina levi 1963 (Araneae, Theridiidae) e evolução da caça em aranhas de teia irregular

Abstract: Orbweb monophyly and its evolution towards monophyletic irregular webs are a recent demonstration of the utility of behaviour on phylogenetic analyses. The loss of web regularity implies a change in prey signal reception by the spider, and therefore should be accompanied by changes in the hunting repertoire. We investigate this hypothesis by comparing hunting tactics in Achaearanea cinnabarina Levi 1963 with that of other theridiids and also with orbweavers. We have videotaped 40 captures of two prey taxa; the… Show more

“…Além da criação de P. nigrispinus, larvas, pupas e adultos de T. molitor podem ser utilizados na criação de outros predadores (Grundy et al, 2000;Zanuncio et al, 2004), parasitoides (Zanuncio et al, 2008;Andrade et al, 2010), pássaros (Martinson;Flaspohler, 2003), morcegos (Mccartney et al, 2007), aranhas (Japyassú;Jotta, 2005), peixes (Ng et al, 2001) e lagartos (Font; Molina-Borja, 2004) e na degradação de resíduos de criatórios de aves (Fischer et al, 2004).…”

“…Web tensing is not a rare behaviour in spiders. It is used for prey detection among groups as diverse as Pholcidae (Japyassú and Macagnan 2004), Scytodidae (Japyassu and Machado 2010), Araneidae (Lubin 1980), Theridiidae (Japyassú and Jotta 2005; Garcia and Japyassú 2005), Tetragnathidae (Yoshida 1990), Nephilidae (Japyassú and Viera 2002), or Mygalomorphae (Coyle 1986) and occurs even among web-less spiders that invade other spiders’ webs (Whitehouse 1986). One of the primary, and basal, functions of spider silk is prey detection, a widespread function present in all major spider groups, from Mesothelae, through Mygalomorphae to Araneomorphae, including Haplogynae and Entelegynae (Coddington and Levi 1991; Blackledge et al 2009).…”

“…The analysis of behavioral sequences detected through the graph methodology herein presented was already employed in a series of studies on spider foraging, in order to detect behavioral differences between experimental treatments (see Japyassú & Viera, 2002), to estimate repertoire amplitude (see Caires & Japyassú, 2003;Garcia & Japyassú, 2005;Japyassú & Jotta, 2005), or to compare repertoire plasticity among different species (see Japyassú, Alberts, Izar, & Sato, 2003). In order to make clearer the usefulness of EthoSeq, not only for the analysis of behavioral sequences but also for the phylogenetic analysis of behavior, we will discuss an example applied to grooming sequences in seven felid species (see Alberts, 1996).…”
