lessons from multi-decadal oceanographic monitoring at an estuarine ecosystem in argentina

both climate change and anthropogenic impact are creating a dynamic of continuous changes in ecosystems. while the expected consequences of these changes are global, the occurrence of extreme events and specific environmental problems are usually local or regional phenomenon. in particular, the coastal ecosystems are among the first vulnerable areas to show those changes; in spite of this, are...

Fatty acids in an estuarine mangrove ecosystem.

Fatty acids have been successfully used to trace the transfer of organic matter in coastal and estuarine food webs. To delineate these web connections, fatty acid profiles were analyzed in species of microbes (Azotobacter vinelandii, and Lactobacillus xylosus), prawns (Metapenaeus monoceros and Macrobrachium rosenbergii) and finfish (Mugil cephalus), that are associated with decomposing leaves ...

Influence of Mangrove Detritus in an Estuarine Ecosystem

This study has determined the relationship and extent of mangrove reduced carbon flow and its contribution to the diet of higher consumers in a nearby seagrass bed using stable isotope techniques. In a seagrass bed approximately 80 m from a riverine mangrove community, detritus from seagrass or other marine sources of carbon such as epiphytes (Stilophora rhizodes) or phytoplankton the major con...

Competing Private Ports—Lessons from Argentina

Private Sector Development Department ▪ Vice Presidency for Finance and Private Sector Development Before Argentina began reforming port operations in 1990, its ports were costly and inefficient. Restrictive labor regulations led to high labor costs. Most ports were open rather than terminal-based, leading to inefficient operating practices and unnecessary costs for cargo handling and storage. ...

Historical comparisons reveal multiple drivers of decadal change of an ecosystem engineer at the range edge

Biogenic reefs are important for habitat provision and coastal protection. Long-term datasets on the distribution and abundance of Sabellaria alveolata (L.) are available from Britain. The aim of this study was to combine historical records and contemporary data to (1) describe spatiotemporal variation in winter temperatures, (2) document short-term and long-term changes in the distribution and...
