Premise of research. Plant silica content depends on the phylogenetic position of a taxon; however, biological or ecological factors may also affect it. In this work, we analyzed data on silicophytolith content from 105 species of South America, exam

Polychaetes and burrowing crabs are widely distributed in intertidal soft bottom environments, playing an important role in structuring infaunal assemblages through trophic and non-trophic interactions such as bioturbation. In southwestern Atlantic (

Effect of Spartina alterniflora Loisel, 1807 on growth of the stout razor clam Tagelus plebeius (Lightfoot, 1786) in a SW Atlantic estuary

Aquatic organisms that produce epibenthic structures such as saltmarsh plants play key roles in habitat functioning through their ecosystem engineering effects. Intertidal Spartina species are well known for modifying tidal hydrodynamic and sediment

Biomass dynamics of the two dominant SW Atlantic Spartina species and its implications on the saltmarsh organic matter accumulation/exportation

Autor: Eugenia Fanjul, Mariana Addino, Macarena S. Valiñas, Oscar Iribarne, M. Fernanda Alvarez, Diana I. Montemayor

Publikováno v: Aquatic Botany. 120:201-204

We present a comparative analysis of the biomass dynamics of the two dominant Spartina plant species in South West Atlantic saltmarshes: Spartina densiflora Brong. (high intertidal zone) and Spartina alterniflora Loesel. (mid-low intertidal zone). We

Interaction strength varies in relation to tidal gradient and spatial heterogeneity in an intertidal Southwest Atlantic estuarine food web

Publikováno v: Journal of Experimental Marine Biology and Ecology. 449:154-164

Interaction strength is a key component in food-web dynamics being highly variable over time and space, de- pending on biotic and abiotic conditions. Intertidal soft bottom ecosystems are essential nursery and feeding sites for migratory shorebirds a

Changes on aggregates morphology and roughness induced by different uses of Typical Argiudolls, Buenos Aires province, Argentina

Autor: Margarita Luisa Osterrieth, Julio L. del Rio, M. Fernanda Alvarez

Publikováno v: Soil and Tillage Research. 119:38-49

Over the last few years, the increase of agriculture in the Pampean plains has led to a significant degradation of the most fertile soils in the country. The aim of our work is to define the effect of soil use on the stability of aggregates, bulk den

Effect of dominant Spartina species on salt marsh detritus production in SW Atlantic estuaries

Publikováno v: Journal of Sea Research. 66:104-110

Two cordgrass species of the genus Spartina cohabit in SW Atlantic (southern Brazil 31o48′ S to Argentinean Patagonia, 43o20′ S) salt marshes. Some salt marshes are dominated by the dense-flowered cordgrass Spartina densiflora (which inhabits the
