This study describes and analyses plant species diversity and identifies indicator species for nitrogen eutrophization in four coastal lagoons in the Araucanian Region, Chile. A total of 82 vascular macrophyte species were identified. Tromen lagoon has the highest species richness (45 taxa), foll...

Floristic comparison and trophic condition based on indicator species in coastal lagoons of the Araucanian Region, Chile
The study of food webs has been a central theme within ecology for decades, and their structure and dynamics have been used to assess a range of key properties of communities (e.g. complexity–stability relationships) and ecosystems (e.g. fluxes of energy and nutrients). However, many food web par...
Southern Patagonia is characterized by the presence of numerous shallow ponds with variable trophic and conductivity conditions, and a relatively high species richness of Crustacea. In the present study, published information and data collected in field work on shallow ponds in the Magellan regio...
