Predation of a large orb-web spider by a crab spider, Thomisus labefactus (Araenae: Thomisidae) [PDF]

open access: yes, 2020
In the present study, I reported that the female adult crab spider Thomisus labefactus preyed on a female adult of the wasp spider Argiope bruennichi in the centre of the web. To my knowledge, the case that a large orb-weaving spider A. bruennichi is fed

Larval growth and biochemical composition of the protected Mediterranean spider crab Maja squinado (Brachyura, Majidae)

open access: yesAquatic Biology, 2014
The spider crab Maja squinado is restricted to the Mediterranean Sea, and as captures of this species became very rare in the last decades, it is a protected species.

Wildflowers-pollinator-crab spider predator food-web as indicator of the agroecosystem biodiversity

open access: yesEcological Indicators, 2022
Wildflowers play a crucial role in the functionality of the agroecosystem food chain. In order to investigate the role of biodiversity in the relationships between wildflowers, relative pollinators and their crab spider predators, six wildflower ...

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

It's Complicated: How Sex, Family, and Season Affect Growth of a Sexually Size Dimorphic Spider

open access: yesIntegrative Zoology, EarlyView.
Extreme female‐biased sexual size dimorphism (SSD) in Nephilingis cruentata emerges when male and female growth trajectories diverge mid‐development. Seasonal effects influence both sexes similarly, but family effects are strongly sex‐specific. These patterns identify a critical developmental window for mechanistic studies of SSD.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...
