The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Classification, Biodiversity and Conservation of Marine Crabs [PDF]
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).The known size of crabs now ...

Comparative aspects of the control of posture and locomotion in the spider crab Libinia emarginata
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.

We sequenced the mitochondrial genomes of the spider crabs Maja crispata and Maja squinado (Majidae, Brachyura). Both genomes contain the whole set of 37 genes characteristic of Bilaterian genomes, encoded on both α- and β-strands.

ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Canal Construction Disrupts Camouflage in Two Sympatric Estuarine Crab Species
Estuarine ecosystems provide essential habitats for fiddler crabs, whose survival heavily relies on background‐matching camouflage. Anthropogenic modifications such as canal construction can alter the visual properties of these habitats, yet direct empirical evidence of their impact on crustacean camouflage remains limited.

Measures of niche overlap are important tools in various ecological and evolutionary studies. Here we create and apply a multispecies overlap metric to both simulated and empirical communities, illustrating how this methodology may capture interactions and structure of niche space in ways that traditional, pairwise metrics overlook.
