      Streptomyces leeuwenhoekii, isolated from the hyperarid Atacama Desert, produces the new ansamycin-like compounds chaxamycins A to D, which possess potent antibacterial activity and moderate antiproliferative activity. We ...
    • Identification assisted by molecular markers of larval parasites in two limpet species (Patellogastropoda: ... 
      Flores, K.; López, Z.; Levicoy, D.; Muñoz Ramírez, Carlos; González Wevar, Claudio; Oliva, M. E.; Cárdenas, L. (Springer Verlag, 2019)
      In the Southern Ocean, many parasites of vertebrates (mainly helminth groups) have been recognized as endemic species, but parasites of marine invertebrates remain almost unknown. It is reasonable to assume that digenean ...
    • Identification of a Holocene aquifer–lagoon system using hydrogeochemical data 
      Sola, F.; Vallejos, A.; Daniele, Linda; Pulido Bosch, A. (Elsevier, 2014)
      The hydrogeochemical characteristics of the Cabo deGata coastal aquifer (southeastern Spain)were studied in an attempt to explain the anomalous salinity of its groundwater. This detritic aquifer is characterised by ...
