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 ...

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.

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

open access: yesIntegrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

open access: yesIntegrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.
