Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, Volume 95, Issue 10, Page 1859-1875, October 2026.
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 ...

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

open access: yesActa Zoologica, Volume 107, Issue 4, Page 450-459, October 2026.
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 ...

Comparative aspects of the control of posture and locomotion in the spider crab Libinia emarginata [PDF]

open access: yes, 2008
The study of pedestrian locomotion in crustaceans has largely focused on forward walking macrurans, or sideway walking brachyurans. The spider crab, Libinia emarginata is a brachyuran that, unlike its close relatives, preferentially walks forward.

Sodium/proton exchange in the gills of three species of crabs : Libinia dubia, Callinectes sapidus, and Menippe mercenaria [PDF]

open access: yes, 1988
Na+/H+ exchange was studied in plasma membrane vesicles from gills of three species of crabs: Callinectes sapidus (blue crab), Libinia dubia (spider crab), and Menippe mercenaria (stone crab).

Spatial and temporal structure of the spider community in the clay semi-desert of western Kazakhstan [PDF]

open access: yes, 2011
The spatial and temporal structure of spider communities was studied in the clay semi-desert of the north-western Caspian Lowland, western Kazakhstan (49°23' N, 46°47' E).

spider

open access: yes, 2021
The complete mitogenome of tarantula spider (Brachypelma boehmei) was sequenced in this study. The complete mitochondrial genome is a typical double-stranded circular molecule of 13,852 bp containing 13 protein-coding genes (PCGs), 22 transfer RNAs ...

Pilot acoustic tracking study on adult spiny lobsters (Palinurus mauritanicus) and spider crabs (Maja squinado) within an artificial reef [PDF]

open access: yes, 2014
Artificial reef areas can be used for management and conservation of commercially exploited crustacean decapods but their behaviour in these environments is poorly characterised.

Classification, Biodiversity and Conservation of Marine Commercial Crabs of India [PDF]

open access: yes, 2017
One of the best known and most intensely studied groups is the true crabs of the infraorder Brachyura. Brachyuran crabs belong to the Order Decapoda, the most diverse group of crustaceans alive today (Ng et al., 2008).
