Two species of herbivorous land crabs from Christmas Island, Cardisoma hirtipes and Gecarcoidea natalis, overlap in both diet and distribution. This study compared the dietary preferences and digestive capabilities of these two species on a diet of leaf litter to establish the digestive strategies each adopts and the likely degree of competition for food. C. hirtipes preferred green to yellow or brown leaves of Ficus macrophylla in short‐term food‐choice experiments. Brown leaves were least… Expand
Dietary assimilation and the digestive strategy of the omnivorous anomuran land crab Birgus latro (Coenobitidae)
On Christmas Island, Indian Ocean, the diet of robber crabs, Birgus latro (Linnaeus) was generally high in fat, storage polysaccharides or protein and largely comprised fruits, seeds, nuts and animalExpand
Feeding ecology of the mangrove crab Ucides cordatus (Ocypodidae): food choice, food quality and assimilation efficiency
It is concluded that high ingestion and assimilation rates of a R. mangle diet together with the consumption of algae allow for a high intake of C, N, and energy, and the digestibility of mangrove leaves by U. cordatus is not hampered by tannins. Expand
Changes in precipitation may alter food preference in an ecosystem engineer, the black land crab, Gecarcinus ruricola
The results were consistent between the single and multiple choice experiments: crabs consumed relatively more apple and fish and only small amounts of lettuce, and the decrease in feeding was likely due to loss of water from the gut resulting in the inability to produce ample digestive juices.

Litter processing and population food intake of the mangrove crab Ucides cordatus in a high intertidal forest in northern Brazil
Diet, feeding periodicity, gastric evacuation rates and size-dependent consumption were determined for this intensively exploited semi-terrestrial crab in different types of mangrove forest, suggesting that the local crab population is food-limited in many parts of the study area. Expand
A review of feeding and nutrition of herbivorous land crabs: adaptations to low quality plant diets
This paper reviews the nutritional ecology, the digestive physiology, and biochemistry of herbivorous land crabs and the adaptations that they possess towards a diet of plant material. Land crabExpand
Feeding Ecology and Ecological Role of North Brazilian Mangrove Crabs
Mangrove trees, leaf consuming and deposit-feeding crabs, and microbenthos form a positive feedback loop that enhances nutrient remineralization, and probably promotes primary and secondary production. Expand
Food preferences of mangrove crabs related to leaf nitrogen compounds in the Segara Anakan Lagoon, Java, Indonesia
It is inferred that the nitrogen compound composition rather than the C/N ratio alone is a determinant for bioavailability of mangrove leaves and hence may partly explain the crabs' food preferences. Expand
Digestive enzymes of two brachyuran and two anomuran land crabs from Christmas Island, Indian Ocean
The digestive ability of four sympatric land crabs species was examined by determining the activity of their digestive enzymes, and the digestive fluid of C. perlatus possessed higher endo-β-1,4-glucanase, lichenase and laminarinase activities compared to that of the other species. Expand
Dietary preferences of brachyuran crabs from Taiwan for marine or terrestrial food sources: evidence based on fatty acid trophic markers
Based on the fatty acid composition, marine/terrestrial herbivory indices were defined and compared with regard to their resolution and differentiating capacity, which can help to reveal trophic preferences of unexplored species, particularly in habitats of border regions like mangrove intertidal flats and estuaries.

Monopolization of litter processing by a dominant land crab on a tropical oceanic island
It is indicated that red crabs monopolize litter processing, removing between 39 and 87% of the annual leaf fall from the forest floor, and translocating organic matter and nutrients into the soil and reducing available habitat for other animals. Expand


Nitrogen Limitation in the Herbivorous Land Crab Cardisoma guanhumi
Although crabs were selective about the plants eaten in their habitat, the choice was not correlated with nitrogen content in the plants and indicates the importance of allochemical defense to both plant survival and actual plant availability to the crabs. Expand
Herbivory in Crabs: Adaptations and Ecological Considerations
The range of herbivory in crabs, as well as the anatomical, physiological and behavioral adaptations that enhance nutrient acquisition from plant material are described. Expand

Because they are both abundant and widespread, red crabs have the potential to be the most important determinant of pattern and process in rain forest on Christmas Island. Expand
