Intragenic homogenization and multiple copies of prey-wrapping silk genes in Argiope garden spiders. [PDF]

open access: yes, 2014
BackgroundSpider silks are spectacular examples of phenotypic diversity arising from adaptive molecular evolution. An individual spider can produce an array of specialized silks, with the majority of constituent silk proteins encoded by members of the ...

Oldest true orb-weaving spider (Araneae: Araneidae) [PDF]

open access: yesBiology Letters, 2006
The aerial orb web woven by spiders of the family Araneidae typifies these organisms to laypersons and scientists alike. Here we describe the oldest fossil species of this family, which is preserved in amber from Álava, Spain and represents the first record of Araneidae from the Lower Cretaceous. The fossils provide direct evidence that all three major

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

open access: yesIntegrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Nomina dubia and faunistic issues with New Zealand spiders(Araneae) [PDF]

open access: yes, 2009
Attempts to clarify the identity of obscure New Zealand spider taxa have lead to the conclusion that six species are best treated as nomina dubia [Philodromus rubrofrontus Urquhart 1891 (Philodromidae); Dictyna urquhartii Roewer 1951, (Dictynidae ...

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...
