VARIATION IN GROWTH PATTERN BETWEEN SOME SECONDARY SEXUAL CHARACTERS IN CRABS (DECAPODA BRACHYURA)
Le croissance relative, chez les crabes, de trois caracteres sexuels secondaires -pinces, abdomen et premiers pleopodes - a fait l'objet d'observations. Il existe de fortes variations specifiquesExpand
THE DETERMINATION OF RELATIVE GROWTH IN CRUSTACEA
TLDR
In Brachyura there is a consistent pattern of phases in the later post-larval life, the critical moults separating the final three phases being known as the pre-puberty and puberty moult respectively. Expand
Grazing of intertidal algae by marine invertebrates
TLDR
Processus d'alimentation des animaux brouteurs; competition interspecifique et niche ecologique; budget energetique; influence du broutage sur la repartition spatiale des algues and the structure des biocenoses intertidales. Expand
Mating in the Brachyura
TLDR
Das Weibchen kopuliert erst wenn die Schale erhartet ist, es gibt nur ein kurzes Liebesspiel and Gesicht- and Gehor-Anreizungen sind dabei am wichtigsten. Expand
Growth in Crustacea – twenty years on
TLDR
Little advance has occurred in understanding the rationale for the diversity of growth patterns, and computer modelling offers promise, but is constrained by lack of data on natural mortality for validation. Expand
Morphology of the genital ducts in female crabs
TLDR
The distribution of the two patterns of duet in the various families of Brachyura is examined, and the phylogenetic implications considered are examined, showing that the Corystoidea is rightly designated a distinct superfamily, and that theorystoida-Portunidae line forms the basic stock of the BrachyURA with sternal female openings.

Spatial and temporal variation in settlement and recruitment of the intertidal barnacle Semibalanus balanoides (L.) (Crustacea: Cirripedia) over a European scale
TLDR
Estimates of total settlement throughout the settlement period and of recruitment at the end of this period both showed substantial variation among locations which was dependent on the year of study, and locations showed distinct differences in the level of post-settlement survival. Expand
Quantifying the density of mangrove crabs: Ocypodidae and Grapsidae
TLDR
Assessment of quick, non-invasive methods for estimating the population density of three species of mangrove crabs in East Africa found that visual counts on Inhaca Island (Mozambique) and at Mida Creek (Kenya) underestimated U. annulipes numbers by 37%, again with no differences between spring and neap tides. Expand
Paradoxical selective feeding on a low-nutrient diet: why do mangrove crabs eat leaves?
TLDR
It is shown that mangrove leaves are unlikely to fulfil the N requirements of crabs, whether or not leaf ageing takes place, and Sediment detritus could be a richer source of N, as shown by lower C/N ratios and regular ingestion by crabs. Expand
