TLDR
Comparisons of the reproductive patterns of the hermit crab populations recorded to date emphasize that reproduction and, consequently, life strategies of hermit crabs are not directly dependent on taxonomic or geographical proximity, but on their evolutionary histories and on local processes acting on each assemblage or population.
Population biology and distribution of the tanaid Kalliapseudes schubarti Mañé-Garzon, 1949, in an intertidal flat in southeastern Brazil.
TLDR
The continuous reproduction, as evidenced by the presence of larval phases (manca II and neutron) and reproductive females throughout the year, and high fecundity among the tanaids associated with fast growth and limited longevity support the case for the opportunistic life strategy suggested for this species in the literature.
The effect of sieve mesh size on the abundance and composition of macrophyte-associated macrofaunal assemblages
TLDR
The results suggest that caution should be exercised when deciding on which sieve to use, as mesh sizes commonly used in benthic studies (1 and 0.5 mm) may result in very different estimates of diversity and abundance, as well as community structure patterns.
Temporal variation of amphipod assemblages associated with Sargassum filipendula (Phaeophyta) and its epiphytes in a subtropical shore
TLDR
The temporal structural variation of the studied algal bed strongly influenced amphipod diversity and assemblage composition, possibly through direct and indirect effects.
Predation on gastropods by shell-breaking crabs: effects on shell availability to hermit crabs
TLDR
Shell availability to hermit crabs was demonstrated to be dependent on predator species and size, gastropod architec- tural defenses, and on the relative predator-prey size, which determined the predatory strategy and the damage inflicted on the shells.
Vertical Distribution of Amphipods Living On Algae of a Brazilian Intertidal Rocky Shore
[La distribution verticale des amphipodes phytophiles des cotes rocheuses d'Itanhaem, Bresil, a ete etudiee pour la premiere fois. Les recherches ont porte sur la distribution et la densite de quinze
Structural variation in the brown alga Sargassum cymosum and its effects on associated amphipod assemblages.
TLDR
The findings show that monospecific algal banks are not homogeneous, and that morphological differences and interactions with other biological substrates can influence the mobile epifaunal assemblages.
Hermit crabs (Crustacea: Decapoda: Anomura), gastropod shells and environmental structure: their relationship in southeastern Brazil
TLDR
Shell utilization and availability varied among sites and shell utilization seemed to be dependent on differences in local shell supply (size and abundance of living snails) and preferences of the hermit crabs for certain shell types.
Patterns of variation in behaviour within and among reef fish species on an isolated tropical island: influence of exposure and substratum
TLDR
Staying close to the substratum was positively correlated to wave exposure for most species and foraging was negatively correlated to exposure for two species, highlighting the activity budgets of fish living in oceanic rocky reefs can be variable and influenced by the local and temporal variation in environmental variables.
