A novel hermit crab optimization algorithm [PDF]

open access: yesScientific Reports, 2023
High-dimensional optimization has numerous potential applications in both academia and industry. It is a major challenge for optimization algorithms to generate very accurate solutions in high-dimensional search spaces.

Evidence of long-term allocentric spatial memory in the Terrestrial Hermit Crab Coenobita compressus. [PDF]

open access: yesPLoS ONE, 2023
Spatial learning is a complex cognitive skill and ecologically important trait scarcely studied in crustaceans. We investigated the ability of the Pacific (Ecuadorian) hermit crab Coenobita compressus, to learn an allocentric spatial task using a ...

Shell resource partitioning as a mechanism of coexistence in two co-occurring terrestrial hermit crab species [PDF]

open access: yesBMC Ecology, 2020
Background Coexistence is enabled by ecological differentiation of the co-occurring species. One possible mechanism thereby is resource partitioning, where each species utilizes a distinct subset of the most limited resource.

Functional morphology of the primary olfactory centers in the brain of the hermit crab Coenobita clypeatus (Anomala, Coenobitidae). [PDF]

open access: yesCell Tissue Res, 2020
Terrestrial hermit crabs of the genus Coenobita display strong behavioral responses to volatile odors and are attracted by chemical cues of various potential food sources.

A new species of hermit crab, Diogenes heteropsammicola (Crustacea, Decapoda, Anomura, Diogenidae), replaces a mutualistic sipunculan in a walking coral symbiosis. [PDF]

open access: yesPLoS ONE, 2017
Symbiont shift is rare in obligate mutualisms because both the partners are reciprocally dependent on and specialized to each other. In the obligate accommodation-transportation mutualism between walking corals and sipunculans, however, an unusual ...

What are the sympatric mechanisms for three species of terrestrial hermit crab (Coenobita rugosus, C. brevimanus, and C. cavipes) in coastal forests? [PDF]

open access: yesPLoS ONE, 2018
Terrestrial hermit crabs play a significant role in coastal ecology. For example, as seed dispersers and debris scavengers in coastal forests, they accelerate the decomposition of organic substances.

Microplastics disrupt hermit crab shell selection. [PDF]

open access: yesBiol Lett, 2020
Microplastics (plastics < 5 mm) are a potential threat to marine biodiversity. However, the effects of microplastic pollution on animal behaviour and cognition are poorly understood. We used shell selection in common European hermit crabs (Pagurus bernhardus) as a model to test whether microplastic exposure impacts the essential survival behaviours ...

Chromosome-level assembly for the complex genome of land hermit crab Coenobita brevimanus [PDF]

open access: yesScientific Data
Land hermit crabs are a group of shell-carrying crabs that have evolved remarkable terrestrial adaptations in behavior, morphology, physiology, and biochemistry. However, the genetic mechanisms underlying these adaptations remain unclear.

Aggression and food resource competition between sympatric hermit crab species. [PDF]

open access: yesPLoS ONE, 2014
The vertical zonation patterns of intertidal organisms have been topics of interest to marine ecologists for many years, with interspecific food competition being implicated as a contributing factor to intertidal community organization. In this study, we

Identification of a hermit crab, Clibanarius signatus, in Hormuz Island abundance, sex ratio and shell selection behaviors [PDF]

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2014
In order to establish a complete list of the hermit crab species in the southern coast of Iran and also determine some of their biological characteristics in the intertidal zones of Hormuz Island, a seasonal sampling collection was conducted in 6 ...
