Abstract The objective of this study was to characterize and compare the hematological variables (erythrogram, thrombogram, leukogram and plasma metabolites) of three cichlid species: Cichla monoculus, Cichla temensis and Cichla vazzoleri. A total of 45 specimens were captured in Balbina lake, Presidente...
Objetivo: quantificar a abundância e a biomassa de moluscos bentônicos no Lago Igapó I, Londrina,
Paraná, Brasil. Material e Métodos: foram realizadas duas coletas no Lago Igapó I, a primeira em
junho de 2015 e a segunda em fevereiro de 2016. O substrato (incluindo os moluscos incrustados)

Abstract Lake Laguna Santa Elena, a freshwater body, located in mid-south of Chile, is an environmental asset used as a water resource by the agricultural and touristic sector and is the habitat for a wide variety of endemic avifauna. The objective of this study was to assign a monetary value to this lac...
Abstract The main objective of the present study was to promote some adaptations to the standard methodology used in the analysis of Cladocera subfossils. The samples used in this study were collected at Lagoa dos Coutos, a temporary lake located on an outcrop with iron-rich duricrust in the Serra do Ga...
El impacto antrópico cercano al lago de Amatitlán ha generado niveles altos de eutrofización que conllevan cambios en la dinámica del ecosistema. Uno de ellos es la proliferación de cianobacterias del género Microcystis que pueden llegar a ser perjudiciales para la fauna y flora de lugar e incluso ...
Se realizó un estudio sobre la composición y abundancia del fitoplancton en el lago de Amatitlán, y el efecto de la calidad de agua sobre su biodiversidad. Para ello, se colectaron muestras de agua en cuatro puntos específicos del lago, en la superficie del agua y a profundidades de 5, 10 y 20 m, de ...

Abstract We evaluated the response of the biomass of aquatic macrophytes under limnological changes after water level fluctuation (WLF) of two tropical reservoirs (R1 and R2), located in northeastern Brazil. Initially we tested the hypothesis that post-WLF limnological conditions and biomass of macrophy...
Abstract Most studies on mechanisms regulating fish larvae processes have focused on assessing the isolated effects of food distribution and feeding behavior. However, in natural ecosystems, fish larvae may strongly interact with zooplankton organisms in an array of complex, direct and indirect interdepe...
Lithium (Li) is widely distributed in nature and has several industrial applications. The largest reserves of Li (over 85%) are in the so-called "triangle of lithium" that includes the Salar de Atacama in Chile, Salar de Uyuni in Bolivia and Salar del Hombre Muerto in Argentina. Recently, the use of micr...
Abstract The effects of extreme droughts on freshwater fish remain unknown worldwide. In this paper, we estimated the condition factor, a measure of relative fitness based on the relationship of body weight to length, in four fish species representing two trophic levels (omnivores and piscivores) from Am...
