Bioscience Journal, 2014 : The use of gastropod shells by hermit crabs is determined by the availability of shells in the environment or through selection for size and volume. This study analyzed patterns in the use of shells by Dardanus insignis (Saussure, 1858).

Daily activity of four tropical intertidal hermit crabs from Southeastern Brazil [PDF]
Brazilian Journal of Biology, 2003 This study describes the daily activity in a simulated high tide situation of four species of hermit crabs (Pagurus criniticornis, Clibanarius antillensis, C. sclopetarius, and C.

Individual quality and personality: bolder males are less fecund in the hermit crabPagurus bernhardus [PDF]
, 2015 One explanation for animal personality is that different behavioural types derive from different life-history strategies. Highly productive individuals, with high growth rates and high fecundity, are assumed to live life at a fast pace showing high ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping
Remote Sensing in Ecology and Conservation, EarlyView.Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Remote Sensing in Ecology and Conservation, EarlyView.This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

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.

Allergy, EarlyView.This study comprehended the allergen profiles of six edible crab species using proteomic and transcriptomic analyses and identified 11 putative allergens. King crab has a distinct protein and allergen profile, with the discovery of malate dehydrogenase as a novel king crab‐specific allergen registered as Para c 11.
