Forested wetlands have hydroperiods that range from permanent to seasonal, constituting an important environmental factor that directly influences the biological activity. This study evaluated how hydrologic dynamics affect the structure of arboreal vegetation in the forested wetlands of southern...

The water bodies studied herein are located in the Huerquehue National Park, a mountain zone with Nothofagus alpina, N. pumilio, N. dombeyi, and Araucaria araucana forests, at 700-1500 m a.s.l. There are numerous oligotrophic lakes, with characteristics similar to the deep Araucanian lakes. Many ...

Cu, Mn, Fe, Zn, Cd and Pb levels were measured in liver and muscle samples of Rainbow Trout Oncorhynchus mykiss collected from three watersheds with different land-uses: native forest, exotic plantation, and agriculture in Chile, during January, April, July, and October 2012. Cd and Pb levels wer...

A study was made of the geographic distribution of swamp forest in the coastal territory of the Araucania Region, Chile. An analysis of maps, aerial photographs, and satellite images was carried out, together with field work, to determine the location, degree of fragmentation, shape of fragments ...

The coastal area of the Araucania Region stands out for the presence of wooded wetlands of Temu and Pitra (Blepharocalyo-Myrceugenietum exsuccae), from the association Blepharocalyo-Myrceugenietum exsuccae. These are nowadays affected by antropic activities. We evaluated the vascular flora, the d...

Chilean Patagonia has protected mountainous areas with evergreen native forests; in which the lakes and rivers, of volcanic or glacial origin, are oligotrophic. In Bulgaria, there are mountainous zones with native forests and associated lakes of volcanic origin. The aim of the present study is to...

Changes in land use which directly or indirectly affect freshwater fauna constitute one of the principal anthropic factors which have caused world biological diversity to disappear rapidly during recent decades. This fauna includes aquatic benthic macroinvertebrates, organisms presenting temporal...

Macrophytes of inland waters are a group of great biological interest. Although lentic systems are ideal for their growth, their presence is not so evident in oligotrophic water bodies, proliferating largely in areas with some level of contamination. A useful tool to determine the presence of a r...

Biological invasions are recognized as one of the major causes of biodiversity loss. Although invasion processes occur in both terrestrial and aquatic environments, freshwater ecosystems are particularly sensitive to invasions impacts. Given that the information on invasive aquatic plants is scar...
