Valeriana carnosa and V. clarionifolia stand out as principal elements in the indigenous pharmacopeias of Patagonia; however, their phytochemical characterization is unknown. This study constitutes starting point a general project that aims to characterize secondary metabolites these species. The variability phenolic compounds root ethanolic extracts was analyzed compared for thirteen populatio...

The sponge fauna from the deep shelf (70 to 200 m) of the Alboran Island (Alboran Sea, Western Mediterranean) was investigated using a combination of ROV surveys and collecting devices in the frame of the EC LIFE+ INDEMARES Grant aimed to designate marine areas of the Nature 2000 Network within Spanish territorial waters. From ROV surveys and 351 examined specimens, a total of 87 sponge species...

The Stress Gradient Hypothesis predicts facilitation will become more important than competition where abiotic stress is high, and the framework successfully positive interactions between species in many systems. Fewer studies have focused on intraspecific facilitation, to our knowledge none examine Pacific Coast salt marshes of North America. We used two that tend occur large, monospecific pat...

PREMISE OF THE STUDY To examine patterns of genetic diversity and test possible hybridization events, microsatellite markers were identified and characterized in Hoya ledongensis (Apocynaceae), and cross-amplification was tested in a congener, H. jianfenglingensis. METHODS AND RESULTS Based on the transcriptome data of H. ledongensis, 46 microsatellite primer pairs were randomly selected for ...
