Shape variation in lentic and lotic tadpoles of Melanophryniscus (Anura: Bufonidae)
(Taylor & Francis Ltd, 2011-08)
The bufonid genus Melanophryniscus includes 26 species that are divided into three phenetic groups based on adult morphology. Larvae develop in environments such as temporary ponds, streams or phytotelms. We studied variation ...
The tadpole of the stream treefrog Hyloscirtus antioquia (Anura: Hylidae: Cophomantini)
(Taylor & Francis Ltd, 2020-08)
We describe the larval morphology of the stream-dwelling tadpole of Hyloscirtus antioquia based on specimens from the type locality, Antioquia, Colombia. The larvae of H. antioquia (belong to the suctorial ecomorphological ...
Ecological drivers of alpha and beta diversity of freshwater invertebrates in arid and semiarid Patagonia (Argentina)
(Elsevier Science, 2019-08)
Freshwater biodiversity is showing a global decline in relation to environmental change and there is an urgent need to quantify different facets of biodiversity to assess the conservation value of freshwater ecosystems. ...
Variability of hydrological connectivity and fish dynamics in a wide subtropical–temperate floodplain
(John Wiley & Sons Ltd, 2019-11)
Fish are subject to diverse stimulus in floodplain rivers resulting from interactions between environmental factors. In such complex and interconnected ecosystems, fish assemblages are thus highly dynamic across space and ...
Water quality index including periphyton chlorophyll-a in forested urban watersheds from Tierra del Fuego (Argentina)
(Elsevier Science, 2021-07)
The city of Ushuaia, Argentina, has experienced a rapid and unorganized population growth with possible consequences on the dynamics and functioning of urban lotic ecosystems. Urban expansion was not largely accompanied ...
Plankton community responses in Pampean lowland streams linked to intensive agricultural pollution
(Elsevier Science, 2021-01)
Lowland lotic ecosystems are under increasing pollution pressure. In this study, we analyzed the plankton community responses to environmental changes, including natural ones and those related to anthropogenic activities, ...
Nutrient concentrations in macrophytes from lotic and lentic environments of the Middle Parana River, Argentina.Concentraciones de nutrientes en macrófitas de ambientes ióticos y lénticos del río Paraná Medio, Argentina
(Pontificia Universidad Javeriana, 2021-05)
Objetivos: el objetivo de este trabajo fue comparar las concentraciones de nutrientes en agua, sedimento y en tejidos vegetales de Eichhornia crassipes y Panicum elephantipes estudiadas en ambientes lóticos y lénticos de ...
Beaver dam effect on phytoplankton and periphyton composition and hydrology in streams from Tierra del Fuego (Argentina)
(Springer, 2020-02)
There is practically no stream or river without non-native beaver impact, past or current, in Tierra del Fuego (TDF), Argentina. In this study, we evaluated the effect of beaver activity on water quality and algal composition ...
