Prevalence and seasonality of Hematodinium (Alveolata: Syndinea) in a Scottish crustacean community. – ICES Journal of Marine Science, 66: 1837–1845. Protist parasites of the genus Hematodinium were detected in seven crustacean species (Cancer pagurus, Carcinus maenas, Liocarcinus depurator, Munida rugosa, Necora puber, Pagurus bernhardus, and Pagurus prideaux) from the Clyde Sea in Scotland. Seasonal screening of different tissues with sensitive molecular probes showed average infection of 3–23%, with prevalence reaching almost 60%

Abstract:
The larval development of the hermit crab Pagurus proximus is described and illustrated from the larvae reared in the laboratory. The development included four zoea and a single megalopa, thus following the typical pattern in the Paguridae. At 20–22°C megalopa of P. proximus was attained 17 to 23 days after hatching. Morphological characters of zoea and megalopa of P. proximus are compared with those described for the related species P. brachiomastus. The distinctive differences between larvae of these two species lend support to the separation of P. proximus from P. brachiomastus. The main la

Abstract:
Abstract The common hermit crab Pagurus bernhardus (Linnaeus, 1758) is an abundant and ecologically important benthic crustacean in the northeastern Atlantic Ocean. While this species has been intensively studied in terms of its ecology, physiology, behavior, and larval development, knowledge about its population structure and demographic history is still lacking. We examined, for the first time, the genetic variability of P. bernhardus by analyzing two mitochondrial gene fragments (CO1 and 16S) from more than 150 specimens collected from various locations from the Iberian Peninsula to Norway.

Abstract:
Dispersion in a littoral population of Pagurus bernhardus in south-west England is shown to be random, with members demonstrating no evidence of site attachment. Movement patterns within the population are shown to be asynchronous and random, and to be dictated by the quantity and quality of each individual's shell contacts. These, in turn, affect the time that individuals spend within the habitat. This implies that population dynamics and residence times are so influenced by the availability of suitable empty gastropod shells that movement and migration in hermit crabs should be regarded as r

Abstract:
A new species of Paguridae, Pagurus ikedai, from the Tokyo Submarine Canyon and vicinity, Japan, is described and fully illustrated, including information on live coloration. This new species is distinguished primarily by size and shape of the chelipeds, in particular the massiveness of the left, and the presence in some males of a papilla or very short sexual tube on the right coxa of the fifth pereopod and a papilla on the coxa of the left. It is assigned to the bernhardus group which now includes eight species.

Abstract:
Hermit crabs use gastropod shells to protect their bodies and developing eggs; an inadequate supply of shells of the appropriate size will, therefore, adversely affect their growth, fecundity and longevity. Since the supply of shells is commonly limited, mechanisms that help to reduce these adverse effects will be selectively advantageous. In Pagurus bernhardus it is suggested that two mechanisms have evolved in this respect: larval settlement is encouraged in the littoral zone where gastropod species are diverse and numerous and where the youngest hermits will find growth potentially unrestri

Abstract:
Aspects of the ecology of Pagurus bernhardus are examined and the strategies which enable this species to exploit two quite different habitats are determined. The area of shell selection is reviewed and mathematical indices of shell adequacy are rejected as biologically flawed. A subjective index is proposed to more accurately describe the quality of a hermit crab shell resource. Shell preference is considered to be an artificial phenomenon and shell selection is demonstrated to be an essentially random process. Shell-limitation is considered one of the most common problems facing all populati

The series of experiments that comprise this thesis used shell fights in the hermit crab Pagurus hernhardus as a model system to address the proximate physiological and whole-organism correlates of contest behaviour. These correlates of fighting ability rangec from the metal ions magnesium (Mg ) and calcium (Ca ), through respiratory pigments and muscular proteins to whole-organism performance capacities and behavioural syndromes. The work presented here thus demonstrates that a suite of physiological and whole organism variables influence contest behaviour in hermit crabs, and that both aerob

Abstract:
Consistent between-individual differences in behaviour (termed “animal personality”) may be driven by adaptive differences in behavioural and physiological life-history traits. The Pace of Life Syndrome (POLS) hypothesis predicts a suit of correlations between those life-history traits along a fast-slow continuum. Therefore, according to the POLS, individuals that are fast-paced would be bolder, more explorative, show high growth-rates, lower immunity and a higher metabolic rate. A mechanistic link between such traits could also explain variation in cognitive traits, where bold individuals are

A field survey was conducted of an extensive intertidal population of <i>Pagurus bernhardus</i> at Mumbles Head, S. Wales. Mean densities of up to 80 m<SUP>-2</SUP> were observed in a rock pool and locally, higher densities of up to 800 m<SUP>-2</SUP> occurred. There was no evidence of tidal or seasonal migration, or emigration from the area although there was an influx of large males from the sublittoral during the breeding season. Sublittoral sampling of the species at a depth of 5 metres on a sandy substrate at Oxwich Bay, Gower, revealed a full range of small individuals in that habitat. C

Abstract:
Animal personality has been demonstrated in a wide range of taxa, including crustaceans. This chapter defines personality as consistent variation in behavior among individuals. It describes related ideas about how individuals can differ in the way they adjust their behavior to match the current situation (“behavioral plasticity”) and how they might differ in how consistent their behavior is within a particular situation (“within individual variation”). Such behavioral variation may represent a component of wider syndromes encompassing among-individual differences in life history traits such as
