Trophic ontogenetic shifts of the dragonfly Rhionaeschna variegata: the role of larvae as predators and prey in Andean wetland communities
(Edp Sciences, 2014-03)
Body size strongly influences the type and strength of species interactions. Animals with complex life cycles, such as dragonflies, usually go through different stages that include a variation in body size and may involve ...
Effects of land use on fish assemblages in Patagonian low order streams
(EDP Sciences, 2009-10)
We assessed the effects of land use on the structure of stream fish assemblages in Northwest Patagonia, Argentina. To this end, a total of 18 sites distributed in 15 streams were sampled during the low water period. At ...
The extent and variability of storm‐induced temperature changes in lakes measured with long‐term and high‐frequency data
(American Society of Limnology and Oceanography, 2021-04)
The intensity and frequency of storms are projected to increase in many regions of the world because of climate change. Storms can alter environmental conditions in many ecosystems. In lakes and reservoirs, storms can ...
Leptophlebiidae (Insecta: Ephemeroptera) from Gorgona Island National Natural Park (Tropical Eastern Pacific, Colombia) with the description of two new species
(Edp Sciences, 2015-12)
Gorgona National Natural Park comprises Gorgona and Gorgonilla Islands, located in the Colombian Pacific at 35 km from mainland. A large-scale study was conducted in Gorgona including samples from benthos and aereal nets ...
Acidophilic phytoplankton of Lake Caviahue, Patagonia, Argentina
(Schweizerbartsche, 2014-07)
This chapter presents a review of the studies carried out over a 10-year period in Lake Caviahue, a natural acidic lake located in Patagonia. The main patterns of the phytoplankton populations are described. Five extremophiles ...
Trophic ecology of syntopic anuran larvae, Rhinella arenarum (Anura: Bufonidae) and Hypsiboas cordobae (Anura: Hylidae): Its relation to the structure of periphyton
(EDP Sciences, 2015-09)
The grazing of amphibian tadpoles has a significant effect on structure and function of freshwater algal communities. The aim of this study was to evaluate the composition of the diet, the amplitude and degree of overlap ...
Impact of water input on plankton temporal dynamics from a managed shallow saline lake
(EDP Sciences, 2017-10)
La Salada is a shallow saline lake located in the SW of the Pampas subject to significant water management, so the primary objective was to assess whether the water input and physicochemical parameters have an impact on ...
Environmental factors restrict the invasion process of Limnoperna fortunei (Mytilidae) in the Neotropical region: A case study from the Andean tributaries
(EDP Sciences, 2011-08)
The golden mussel Limnoperna fortunei was introduced into Argentina in 1991 and has since been spreading through the Plata and Guaíba basins at a rate of 240 km.year−1. To assess their ability to invade the Andean tributaries ...
Effects of volcanic ash on assemblage patterns and biological traits of Chironomidae in a north Andean Patagonian stream, Argentina
(EDP Sciences, 2017-01)
The Puyehue-Cordón Caulle Volcanic Complex eruption occurred on June 4, 2011 (2236 m a.s.l. 40°32′S, 72°7′W). As a consequence, wide areas of Argentina were covered by volcanic ash. In order to investigate the effects of ...
Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
