“…This species occupies a particularly important position because of its continuous geographic distribution (Amapá to Santa Catarina in Brazil, according to Castro et al, 2008). This ucidid crab lives exclusively in tropical and subtropical mangrove ecosystems, where it builds burrows in the sediment (Hattori and Pinheiro, 2003) and uses the leaves and propagules of mangrove trees as its source of food (Christofoletti et al, 2013). This crustacean is a central component of the benthic mangrove macrofauna (Alves and Nishida, 2004) and a vital fishery resource to artisanal fishermen (Rodrigues et al, 2000).…”

“…Physical parameters were recorded within each site. Vegetation lining the intertidal banks, known as a food source for many intertidal crabs (Christofoletti et al 2013;Ferreira et al 2013;Bui and Lee 2014), was recorded in one of the four vegetation classes described earlier. Canopy overhang, known to provide shelter , was recorded in 10 % classes, established as the proportion of the site covered by canopy as observed from the boat.…”

Intertidal crabs are abundant in tropical estuaries and have bio-indicator potential. However, the use of intertidal crabs in guiding management actions is limited because highreplication, cost-effective tools to analyze their distribution patterns at large scales are lacking. This study used assemblage modeling and photography to rapidly build formal understanding of the spatial organization of crab communities in the low intertidal zone, between mean sea level at low spring tide and the edge of the mangrove forest, within and among estuaries. A classification and regression tree model revealed seven distinct habitats based on relative occurrence of five species (Uca coarctata, Uca seismella, Macrophthalmus japonicus, Metopograpsus frontalis, and Metopograpsus latifrons) among eight estuaries along 160 km of coast in North Queensland, Australia (18°28′-19°25′ S, 146°12′-147°14′ E), across four sampling trips between April 2009 and October 2010. Photography provided high-replication sampling across a large area relative to the aim of the study but did not represent the whole intertidal crab community. Complementary hand collections within one estuary allowed the occurrences of three other species (Perisesarma longicristatum, Australoplax tridentata, and Metopograpsus thukuhar) to be fitted into the model. Species occurred across habitats, yet a high occurrence of different species characterized each habitat. The presence of some species not usually found on low intertidal banks suggested connectivity across the intertidal landscape. The model provided a formal basis to add previous small "site or transect specific" scale spatial distribution knowledge as well as other ecological information. Areas with outlying values can be identified as research and management priorities in the absence of other information, although this prioritization should be done with care. The approach may be transferable to other organisms and systems to provide rapid, cost-effective information on the distribution of key fauna where background understanding and resources are limited.

“…Leaves found on the sediment are the primary food source for this species (Nordhaus and Wolff, 2007;Nordhaus et al, 2009). Christofoletti et al (2013) suggest that crabs prefer Avicennia leaves, which are more nutritious compared to other mangrove plant species. R. mangle and L. racemosa have higher levels of sclerophylly and chemical defenses, lower tissue nutrient concentrations and thicker root epidermis, making them more resistant to herbivores, pathogens (Feller and Chamberlain, 2007) and tissue breakdown (Middleton and McKee, 2001).…”
