| predator diet and trophic position modified with altered habitat morphology. | empirical patterns that emerge from an examination of food webs over gradients of environmental variation can help to predict the implications of anthropogenic disturbance on ecosystems. this "dynamic food web approach" is rarely applied at the coastal margin where aquatic and terrestrial systems are coupled and human development activities are often concentrated. we propose a simple model of ghost crab (ocypode quadrata) feeding that predicts changing dominant prey (emerita talpoida, talorchest ... | 2016 | 26824766 |
