Abstract:
... Lakes and reservoirs present contrasting differences regarding origin, age and trophic state that may influence their biological communities. In the face of the inevitably rising number of reservoirs worldwide, our objective was to investigate the differences in zooplankton community structure and diversity patterns from 98 tropical shallow lakes and reservoirs (northeast Brazil). We tested the hy ...

Abstract:
... Water abstraction for irrigation has an important effect on stream organisms in general and aquatic macroinvertebrates in particular. The alteration of flow modifies the habitat conditions and creates important ecological constraints for many of these animals, so shaping the communities and affecting their diversity. With the aim to assess the impact of flow and habitat changes due to water abstra ...

Abstract:
... Four major categories of food items were determined in the gut content of chironomid larvae collected in the Curonian and Vistula Lagoons in the spring–summer period of 2009–2011. These were detritus (range from 88 to 92% of the gut content, by volume), matter of plant (2–7%) and animal origin (0.2–0.5%), and mineral particles (3–7%). Plant matter comprised pine pollen, conidia of fungi, cyanobact ...

The food webs of a coastal lagoon ecosystem in the southeastern Gulf of California were investigated through the use of stomach contents analyses and carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotopes of fish and macroinvertebrates. Food sources and species representative of primary producers and primary-to-tertiary consumers were examined. Macroinvertebrates (47.5%) and fish (45%) assemblages repr ...

Abstract:
... Eutrophication, which causes cyanobacterial blooms, is a worldwide concern leading to further deterioration in water quality and adverse changes in the ecosystems due to oxygen consumption of decomposing cell masses. The investigation of extracellular polymeric substances (EPSs) contributes to a better understanding of the growth and proliferation of cyanobacteria. It could be a key to prevent blo ...

Abstract:
... Aquatic habitats have been highly modified by human actions that reduce their native diversity and create conditions suitable for tolerant alien species. Pomacea maculata was detected in 2009 in both the alluvial plain and the final stretch of the Ebro River. Since then, a permanent population has stabilized in the littoral area of the river where the water level fluctuates according to the river ...

Abstract:
... Shallow lakes are often affected by the increase in nutrients and global climate change, with frequent occurrences of cyanobacterial blooms. In this context, the biomanipulation of the higher trophic levels, such as zooplankton, can efficiently control these blooms. Based on this, this study aimed to verify the potential of a medium-sized cladoceran, Macrothrix spinosa, to control the phytoplankto ...

The aim of this study was to test the hypothesis that a widespread non-native fish species in Brazil displays opportunistic feeding behavior and changes its diet according to environmental conditions. We compared the diet, feeding selectivity, carbon assimilation, trophic niche, and trophic level of Knodus moenkhausii (a small non-native characid fish species of Upper Paraná River) in streams surr ...

Abstract:
... There are numerous examples of species introductions that have caused declines in native populations. In many cases, exotic species are predators of native prey which do not respond correctly to these new and often much different threats. Amphibians, as a group, have been strongly affected by introductions of fish and other aquatic predators such as crayfish. Our goal in this study was to explore ...

Abstract:
... The purpose of this study was to examine the use of industrial sand and commercial salts for mimicking brackish systems in laboratory and greenhouse experiments. Many wetland and freshwater aquatic plants are adversely affected by salt stress and increased salinity concentrations. Sea level rise can increase salinity in aquatic ecosystems and shift vegetation compositions toward more salt-tolerant ...

In this study, the amphibian macrophyte Polygonum punctatum was evaluated as a temporary habitat and feeding ground for fish (≤ 108 mm) during the flood period in a river–floodplain ecosystem. The fish were sampled in January and February of 2015 in a lake of the Upper Paraná Rive ...

Abstract:
... Many organisms that live in inland standing waters produce dormant life stages that can accumulate in propagule banks to survive temporarily unfavourable periods. These egg banks have important effects on the ecology of populations and communities in terms of phenology, population densities, the probability of extinction, species diversity and habitat connectivity in time and space. They also have ...
