- Abstract:
- ... The links between vegetation and soil biota are responsible for a variety of ecosystem processes and services that can be affected by grazing. In this study, we aimed to evaluate the effects of grazing frequency in natural grasslands’ biodiversity (plant and collembola communities) and on ecosystem processes (decomposition and biomass accumulation). For so, we carried out a clipping experiment ove ...

- Abstract:
- ... Heavy metals are different from other toxic agents because they are not metabolized, destroyed and excreted. They reach water resources mainly through anthropic action, be it agricultural, industrial, occupational, among others. Fish, often exposed to such contamination, are an important source of food in the Tramandaí River Basin (TRB) and stand out for their commercial importance. Increased acti ...

- Abstract:

Such impacts can modify the functional structure of fish communities, although the exact consequences of anthropic land-use changes can be context-dependent. This study investigated the influence of different land-use classe ...

The objectives of this study were to investigate the food resources consumed by two species of detritivorous fishes along the Apodi‐Mossoró River reservoir cascade system, located in the tropical semi‐arid region of Brazil. The hypotheses tested were as follows: (a) the diet, niche breadth and niche overlap of the species in the reservoirs downstream of the cascade are different due to the blockag ...

Brazilian soils can have high concentrations of toxic elements, mainly mercury (Hg) and arsenic (As), metals also associated with anthropogenic activities (e.g. intensive agriculture, mining, deforestation and hydroelectric plants). This can lead to large amounts of these elements reaching and/or being mobilized in the aquatic ecosystem, which constitutes a serious threat to the environment and to ...

Marine ecosystems are reported to be contaminated by microplastics (MPs) (< 5 mm); however, the ecological mechanisms involved in the ingestion of debris by marine organisms are relatively unknown. By developing and optimising an appropriate protocol of gut digestion for fish species, this study explores a tropical estuarine environment to unriddle the processes responsible for the different inges ...

The Lower Amazon region (Western Pará, northern Brazil) is greatly affected by mining exploitations (particularly artisanal gold mines) and other industrial and intensive agricultural activities with potentially strong impacts on aquatic ecosystems.

- Abstract:
- ... The number of dams has had a significant increase in the last six decades, altering the physiography of rivers and creating systems of reservoirs in series. Therefore, it is expected that in a cascade of reservoirs, detritivorous fish will be especially affected due to the loss of nutritional quality in these regions, resulted from the high sedimentation of nutrients and organic matter. The object ...

- Abstract:
- ... Several dozen fish species have been introduced into Neotropical waters, causing significant biotic changes that include deterministic predation interactions with ecosystem effects. In general, reservoirs are preferred over lakes as places for stocking policies, due to their artificial aspect, consequently promoting fish introductions. In a meta‐analytic approach, we compared the biomass of plankt ...
