Mollusks as ecosystem engineers: the role of shell production in aquatic habitats
Mollusk shells are abundant, persistent, ubiquitous physical structures in aquatic habitats. Using an ecosystem engineering perspective, we identify general roles of mollusk shell production inExpand

Contrasting Effects of Two Burrowing Crabs (Chasmagnathus granulata and Uca uruguayensis) on Sediment Composition and Transport in Estuarine Environments
The burrowing crabs Chasmagnathus granulata and Uca uruguayensis are important bioturbators of intertidal flats in SW Atlantic estuaries reworking large amounts of sediment (C. granulata 2234·6 gExpand

Direct and indirect effects of burrowing crab Chasmagnathus granulatus activities on erosion of southwest Atlantic Sarcocornia‐dominated marshes
Using field measurements and field experiments, we investigated the effect of a dominant Southwest Atlantic intertidal burrowing crab, Chasmagnathus granulatus, on the inland growth of tidal creeksExpand

Eutrophication and macroalgal blooms in temperate and tropical coastal waters: nutrient enrichment experiments with Ulva spp.
Receiving coastal waters and estuaries are among the most nutrient-enriched environments on earth, and one of the symptoms of the resulting eutrophication is the proliferation of opportunistic,Expand

The role of the Río de la Plata bottom salinity front in accumulating debris.
The Río de la Plata, one of the most important South American estuarine environments, is characterized by a bottom salinity front that generates an ecotone between the river and the estuary. Based onExpand

The invasion of Undaria pinnatifida to a Macrocystis pyrifera kelp in Patagonia (Argentina, south-west Atlantic)
Biological invasions can alter the biodiversity of native communities generating an ecological impact that in many cases is irreversible. In 2001, Undaria pinnatifida invaded Macrocystis pyriferaExpand

Predation on the southwestern Atlantic fiddler crab (Uca uruguayensis) by migratory shorebirds (pluvialis dominica, P. squatarola, arenaria interpres, and numenius phaeopus)
In Bahia Samborombon (SW Atlantic; 35°30′–36°22′S; 56°45′–57°23′W) migratory American golden plover (Pluvialis dominica), black-billed plover (P. squatarola), ruddy turnstone (Arenaria interpres),Expand

Physical effects of an invading reef-building polychaete on an Argentinean estuarine environment
Abstract Although the environmental impact of invasive species is variable, ecosystem engineers usually dramatically modify the ecosystem through different mechanisms. Here, we evaluated physicalExpand
