1. Associations between jumping spiders (Salticidae) and Bromeliaceae / Associações entre aranhas Salticidae e Bromeliaceae : historia natural, distribuição espacial e mutualismos
The understanding of the interactions between arthropods and plants has grown considerably in the last few years. Although the spiders are among the most abundant arthropod group and compose the main predator guild on vegetation, there exist very few studies involving spiders and plants. Here, we report information showing that some salticid species are stri

2. A review of some south american species of jumping spiders (Araneae: Salticidae) described by Mello-Leitão from Brasil, with resolution of the genus Asaphobelis
Os tipos de 18 espécies de Salticidae descritas por Mello-Leitão para o Brasil foram re-examinados e redescritos quando necessário. As seguintes mudanças nomenclaturais foram propostas: Novas sinonímias: Akela quinquevittata Mello-Leitão 1947 = Ilargus coccineus Simon 1901; Asaphobelis pluripunctatus Mello-Leitão 1947 = Asaphobelis physonychus Simon 1

3. Trichobothrial mediation of an aquatic escape response: Directional jumps by the fishing spider, Dolomedes triton, foil frog attacks
Fishing spiders (Pisauridae) frequent the surfaces of ponds and streams and thereby expose themselves to predation by a variety of aquatic and semi-aquatic vertebrates. To assess the possibility that the impressive jumps of fishing spiders from the water surface function in evading attacks by frogs, attacks by bullfrogs (Rana catesbiana) and green frogs (R.

4. Firefly “femmes fatales” acquire defensive steroids (lucibufagins) from their firefly prey
Female fireflies of the genus Photuris, the so-called firefly “femmes fatales,” prey on male fireflies of the genus Photinus. The females are able to entrap the males by faking the flash signal characteristics of the Photinus female. We found that by feeding on Photinus males, Photuris females gain more than nutrients. They also acquire defensive s

5. Sexual selection driving diversification in jumping spiders
Theory predicts that speciation rates should be accelerated in organisms undergoing sexual selection. In systems involving female choice, sexual selection acts directly on traits that may be important in prezygotic reproductive isolation, potentially fostering rapid divergence of such traits among allopatric populations. Despite the appeal of this concept, i
