Acidic Residues Control the Dimerization of the N-terminal Domain of Black Widow Spiders’ Major Ampullate Spidroin 1 [PDF]

, 2016
Dragline silk is the most prominent amongst spider silks and comprises two types of major ampullate spidroins (MaSp) differing in their proline content. In the natural spinning process, the conversion of soluble MaSp into a tough fiber is, amongst other ...

Molecular insights into the biogeography and species status of New Zealand's endemic Latrodectus spider species; L. katipo and L. atritus (Araneae, Theridiidae) [PDF]

, 1998
New Zealand's endemic sand dune Latrodectus widow spider species, L. katipo and L. atritus, possess behavioral and physiological attributes likely to promote dispersal over large distances.

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

Integrative 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.

Lepidodactylus lugubris (Squamata: Gekkonidae) als Beute von Pholcus phalangioides (Araneae: Pholcidae) [PDF]

, 2012
Es gibt zahlreiche Publikationen, die dokumentieren, dass Wirbeltiere in das Beutespektrum von Spinnen gehören können, wobei offensichtlich insbesondere Amphibien und Reptilien erbeutet werden (z.B. De Armas 2001, Menin et al.

Vertebrate prey capture by Latrodectus mactans (Walckenaer, 1805) and Steatoda triangulosa (Walckenaer, 1802) (Araneae, Theridiidae) provide further insights into the immobilization and hoisting mechanisms of large prey

, 2021
Spider species across 27 families have been recorded naturally preying upon vertebrates. Intricate three-dimensional webs, predation strategies, and potent neurotoxic venom allow Latrodectus and Steatoda spiders to subdue vertebrate prey that are many ...

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

Integrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Spiders have rich pigmentary and structural colour palettes [PDF]

, 2017
Elucidating the mechanisms of colour production in organisms is important for understanding how selection acts upon a variety of behaviours. Spiders provide many spectacular examples of colours used in courtship, predation, defence and thermoregulation ...

Does female control and male mating system predict courtship investment and mating outcomes? A comparative study in five widow spider species (genus Latrodectus) tested under similar laboratory conditions

BMC Ecology and Evolution
Background Male courtship investment may evolve in response to the male’s expectation of future mating opportunities or the degree of female control during mating interactions.
