    BREEDING BIOLOGY OF THE SOUTHERN HOUSE WREN ON CHILOE ISLAND, SOUTHERN CHILE
    (2012) Ippi, Silvina; Vasquez, Rodrigo A.; Moreno, Juan; Merino, Santiago; Villavicencio, Camila P.
    We studied the breeding biology of a Southern House Wren (Troglodytes aedon chilensis) population using nest boxes on Chiloe Island, southern Chile (41 degrees S) to make latitudinal comparisons at the intraspecific level. There were no significant differences in body size between adult males and females, although wings were significantly longer in males. Clutch size averaged 4.3 eggs per nest, and brood size was 3.9 nestlings. Egg size averaged 17.3 mm in length and 13.2 mm in width. Incubation and nestling periods averaged 16 days each. The Southern House Wren on Chiloe Island has a larger clutch size than in the tropics, but a smaller clutch size than populations at the same latitude in the Northern Hemisphere. The Southern House Wren has larger eggs and a longer incubation period but a similar nestling period as House Wrens in the Northern Hemisphere. Received 23 August 2011. Accepted 29 January 2012.

    Creation of the first national biorepository of multi-resistant bacteria available for the study of bacterial resistance in Chile
    (2022) Garcia, Patricia; Rivas, Lina; Peters, Anne; Henriquez, Paola; Castillo, Loriana; Illesca, Vijna; Maripani, Andrea; Moreno, Juan; Muhlhauser, Margareta; Porte, Lorena; Rioseco, Maria Luisa; Rojas, Pamela; Silva, Francisco; Suazo, Patricio; Munita, Jose M.
    The availability of bacterial strains for the study of bacterial resis-tance is key to advances in basic and clinical research. There are few biobanks of bacteria with known resistance mechanisms, isolated from clinically significant infections. A review of the literature reveals that only in the United States of America is there a biobank of resistant isolates. This publication shows the creation of the first biorepository of resistant bacteria Chile associated with the MICROB-R Laboratory Network, with the participation of 11 centers distributed throughout the country, which to date has more than 3,500 bacterial isolates studied phenotypically and genotypically, available to the Chilean scientific community.
