| This study details for the first time the food habits of the culpeo or Andean fox (Lycalopex culpaeus) in high areas of the Ecuadorian Andes during a complete annual cycle. Our objective was to identify prey species, calculate their contribution to diet and test for temporal variation. In total, 304 Andean fox scats were collected within the Podocarpus National Park (Loja province, southern Ecuador). By analysing the content of scats 413 prey items were identified and classified into eight prey groups. Subsequently, the frequency of occurrence (FO) for each prey group was calculated per month together with the relative contribution of estimated consumed biomass (CB). In addition, the Shannon-Wiener’s index was calculated as a measurement of monthly diet... |

| Se estudió el crecimiento poblacional de la cepa Brachionus sp. “Cayman”, cepa Chilca, Perú, en respuesta a diferentes tratamientos con microalgas: Isochrysis galbana (T1), Chaetoceros gracilis (T2), Nannochloropsis oculata (T3), Isochrysis galbana + Chaetoceros gracilis + Nannochloris maculata (T4), Isochrysis galbana + Nannochloris maculata + Nannochloropsis oculata (T5) y Nannochloris maculata (T6). Se evaluó la densidad final de la población (DF), tasa de crecimiento (TC) y productividad (R). Los resultados mostraron diferencias estadísticas entre los tratamientos, encontrándose que T5 presentó mejores resultados en cuanto a DF (190 ± 5,51 indiv.mL-1), TC (0,40 ± 0,01 día-1) y R (38 080 ± 1,53 rot.L-1.día-1). |
