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

Journal of Animal Ecology, EarlyView.This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

LIMULUS - PAST, PRESENT AND FUTURE [PDF]
Medicamentul Veterinar, 2016 Related rather to spider and scorpion, these blue-blooded, forgotten by time, Horseshoe crab own some of the most interesting secrets. This shellfish has survived on Earth for millions of years 562/450, without suffering major changes.

A new genus for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836 (Crustacea, Brachyura, Majoidea), based on morphology and molecular data [PDF]
Zoosystematics and Evolution, 2020 A new genus of majoid spider crab, Pohleus gen. nov. is established for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836, based on morphology and molecular data from the partial sequences of the 12S and 16S mitochondrial genes ...

Integrative 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
Integrative 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.
