| can amino acid carbon isotope ratios distinguish primary producers in a mangrove ecosystem? | the relative contribution of carbon from terrestrial vs. marine primary producers to mangrove-based food webs can be challenging to resolve with bulk carbon isotope ratios (δ(13)c). in this study we explore whether patterns of δ(13)c values among amino acids (aas) can provide an additional tool for resolving terrestrial and marine origins of carbon. | 2012 | 22638971 |
| transisthmian differentiation in the tree-climbing mangrove crab aratus h. milne edwards, 1853 (crustacea, brachyura, sesarmidae), with description of a new species from the tropical eastern pacific. | the tree-climbing mangrove crab aratus pisonii (h. milne edwards, 1837) (brachyura, sesarmidae) is considered to have a transisthmian distribution, due to its presence in mangroves of the western atlantic as well as the eastern pacific. we here present evidence, based on the morphologies of male gonopods and on genetic data, that populations from these two coastlines are morphologically and genetically distinct and require the description of a new species, aratus pacificus n. sp., as the sister- ... | 2014 | 24870191 |
| ascomycetous yeast communities of marine invertebrates in a southeast brazilian mangrove ecosystem. | the ascomycetous yeast communities associated with 3 bivalve mollusk, and 4 crab species were studied in the mangrove at coroa grande on sepetiba bay in rio de janeiro, brazil. these were made up mostly of diverse but sparse and apparently allochtonous yeast populations. the striking exception was a prevalent population of the species kluyveromyces aestuarii, which predominated the yeast communities of 2 detritus feeding crabs, sesarma rectum and uca spp., and the shipworm neoteredo reynei. howe ... | 1995 | 8546456 |
| herbivore responses to nutrient enrichment and landscape heterogeneity in a mangrove ecosystem. | complex gradients in forest structure across the landscape of offshore mangrove islands in belize are associated with nutrient deficiency and flooding. while nutrient availability can affect many ecological processes, here we investigate how n and p enrichment interact with forest structure in three distinct zones (fringe, transition, dwarf) to alter patterns of herbivory as a function of folivory, loss of yield, and tissue mining. the effects of nutrient addition and zone varied by functional f ... | 2007 | 17566784 |
