1. Pharmacological characterization of venoms from three theraphosid spiders: Poecilotheria regalis, Ceratogyrus darlingi and Brachypelma epicureanum
Abstract Background Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms from three taxonomically different theraphos

2. Is more better? Sexual confusion during courtship between two sympatric and synchronic tarantulas: Acanthoscurria suina and Eupalaestrus weijenberghi
When two similar species co-occur in time and space, strong mechanisms isolating them from each other are expected. Acanthoscurria suina Pocock, 1903 and Eupalaestrus weijenberghi (Thorell, 1894) are two sympatric and synchronic tarantulas that inhabit burrows in Uruguay's meadows. Here we test how and when reproductive isolation operates between these speci

3. Morphology, evolution and usage of urticating setae by tarantulas (Araneae: Theraphosidae)
Urticating setae are exclusive to New World tarantulas and are found in approximately 90% of the New World species. Six morphological types have been proposed and, in several species, two morphological types can be found in the same individual. In the past few years, there has been growing concern to learn more about urticating setae, but many questions stil

4. Expressão e purificação de proteínas de glândulas produtoras de seda das aranhas Nephilengys cruentata e Avicularia juruensis.
Sedas são compostos protéicos secretadas por glândulas especializadas encontradas em diferentes grupos de artrópodes. Aranhas produzem uma diversidade de fibras, que são predominantemente compostas por proteínas repetitivas (espidroínas), codificadas por uma família multigênica. A caracterização dessa família está focada em espidroínas sintetiz

6. Analise histologica do aparato venenifero e caracterização farmaco-bioquimica da peçonha de Vitalius dubius (Araneae, Theraphosidae) / Histological analysis of the venom apparatus and biochemical and pharmacological characterization of venom from Vitalius dubius (Araneae, Theraphosidae)
Vitalius dubius is a medium-sized, non-aggressive tarantula found in southeastern Brazil. In this work, we examined the histological organization of the venom apparatus of V. dubius and investigated some biochemical and pharmacological properties of this spider´s venom. The venom apparatus consisted of two chelicerae fitted with large fangs for prey immobil

7. The stridulatory setae of Acanthoscurria suina (Araneae, Theraphosidae) and their possible role in sexual communication: an experimental approach
Specialized setae placed on proximal segments of appendages in tarantulas have been related to sound production (stridulation), used in defense or sexual communication. The surface structure of called stridulatory setae of Acanthoscurria suina Pocock, 1903 was studied by SEM. Three morphological types of setae were recognized and at least two of them could b
