Nitrogen Dynamics in the Mangrove Sediments Affected by Crabs in the Intertidal Regions

Ecotoxicology, 2020
Crab is an important benthonic animal in mangrove ecosystem, however, the potential function of crabs on nitrogen (N) transformation in mangrove ecosystems is still poorly understood. The present study aimed to explore the potential effect of crab burrows on nitrification/denitrification within the sediments.

Hermit crabs, humans and Mozambique mangroves

African Journal of Ecology, 2001
AbstractThere is a complex interrelationship between upper shore hermit crabs (such as Coenobita sp. and Clibanarius sp.), coastal human populations and mangrove forests in Mozambique. The abundance, activity, shell selection and behaviour of three species of hermit crab are related to the level of mangrove cover.

Saving the overlooked mangrove horseshoe crabs-A perspective from enhancing mangrove ecosystem conservation

Marine Environmental Research
Despite being widely distributed in Asia, Carcinoscorpius rotundicauda is often overlooked and, its population status remains unclear. Moreover, it is threatened by illegal harvesting and degradation of mangrove ecosystems. Protecting its habitat is essential for population and biodiversity conservation, as mangroves provide nursery grounds and food ...

Quantifying the density of mangrove crabs: Ocypodidae and Grapsidae

Marine Biology, 2002
Numerous studies have highlighted the importance of crabs within mangrove ecosystems, but tested methods of enumeration are virtually non-existent. The aim of the present study was to assess the accuracy of quick, non-invasive methods for estimating the population density of three species of mangrove crabs in East Africa: Uca annulipes, Sesarma ...

Ionic regulation in the mangrove crab Goniopsis cruentata

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. The blood concentrations of sodium, chloride, magnesium and sulphate decreased slightly, and those of potassium and calcium remained constant, when crabs were adapted to external concentrations ranging from 100% down to 5% seawater. 2. 2. The blood volume (ca. 26% of the body weight) remained constant over the range 100-25% SW.

Mangrove Crab Gills as a Microbial Ecological Niche

2023
Mangrove ecosystems display high variability of multiple environmental factors across the sea-land gradient, leading to the selection of organisms with specific evolutionary adaptations. Among them, Brachyuran crabs are one of the most ecologically relevant taxa, showing different degrees of terrestrial adaptation and occupying different ecological ...

The Occurrence and Distribution of Crabs in a Jamaican Mangrove Swamp

The Journal of Animal Ecology, 1969
The zonation of animals and plants in mangrove swamps is often greatly complicated by the structure of the swamps. Developing in sheltered areas, often around river mouths, extensive mangrove swamps are interlaced with drainage and tidal channels, and contain semi-stagnant lagoons, deep mud banks, thickets of mangrove and the occasional island of hot ...

Feeding and burrowing ecology of two East African mangrove crabs

Marine Biology, 1991
The behavior and ecology of two mangrove crabs,Sesarma meinerti De Man, 1887 andCardisoma carnifex (Herbst, 1794) were investigated at the beginning of the rainy season (October–November 1988) at Mida Creek, Kenya. Both species occupy upper intertidal levels, above mean high-water neap, and completely overlap in their zonation. Each burrow lasts ca.
