1. Trophic interactions among sympatric zooplanktivorous fish species in volume change conditions in a large, shallow, tropical lake
Significant reductions in the water volume of shallow lakes impose a restriction on species segregation promoting more interactions in the trophic relationships. The diets of three closely related zooplanktivorous silversides belonging to the Atherinopsidae species flock of lake Chapala , Mexico, were analyzed at two sites (Chirostoma jordani, C. labarcae, a

2. Spatial patterns of zooplanktivore Chirostoma species (Atherinopsidae) during water-level fluctuation in the shallow tropical Lake Chapala, Mexico: seasonal and interannual analysis
This study addresses the influence of water-level fluctuations on fish distribution at two temporal scales: seasonal (dry and rainy) and interannual (low and high volume conditions). The analysis of abundance relationships among three zooplanktivore Chirostoma species at fifteen sites in Lake Chapala, Mexico, revealed the significant influence of contrasting

3. Avaliação limnológica da lagoa central (Município de Lagoa Santa - MG): uma abordagem espacial
The concern about the decrease of ecological health of freshwater resources has been increasing dramatically in recent years. Therefore, there is a huge demand of finding new technologies aimed at the recovery and conservation of freshwater resources specially in the tropical belt. Accordingly, the application of new technologies such as GIS (Geographic Info

4. Variação espacial e temporal da comunidade fitoplanctônica da Lagoa Bonita, DF
The Distrito Federal has few natural lagoons. Between them distinguishes the Lagoa Bonita located in Estação Ecológica de Águas Emendadas (15 32 to 15 38 S and 47 33 to 47 37 W). The objective of this work was to analyse the structure and dynamics of the phytoplankton community of Lagoa Bonita considering its spatial and temporal variation. The phytoplan

5. Limnologia comparativa de três lagoas neotropicais da Bacia do Magdalena Médio Santandereano (Colômbia), com ênfase no estudo da diversidade da comunidadezooplanctônica e sua relação com a dinâmica hidrológica do sistema regional.
Few studies have been developed regarding zooplankton diversity in Neotropical Region, particularly in Colombia. Regarding the diversity in the Tropical region still there are a great controversy, despite the relevance of this community as indicator of climate or hydrological, physical and chemical changes. A limnological study was performed during the perio
