It can also additionally shape on a extensive kind of surfaces, along with residing tissues, scientific devices, commercial or potable water device pipe or herbal aquatic systems. A well-assorted organism inclusive of algae, micro organism, protozoa, arthropods, etc. can be determined withinside the biofilm assemblage. ...
Analysis of the root system is important in ensuring sustainable crop production, reducing nutrient input and irrigation, and protecting soil carbon pools. ...
There are environmental concerns due to pollution caused by the runoff of unused fertilizers, which causes the eutrophication of aquatic systems. The overuse of water through irrigation and the resultant depletion of groundwater and surface water reserves also make farming unsustainable. ...
Growth inhibitor, allergens and other anti-nutritional factors largely inactivated during extrusion cooking. Manufacturing Soft Aquatic Pellets Some species like blue fin tuna prefer very soft pellet. ...
A ‘membrane-denitrification’ reactor (MDR) was developed and tested in a semi-technical recirculation aquaculture system in comparison to a double – without MDR – as reference system. ...
Due to agricultural runoffs, drainage and leaching it reaches surface waters at concentrations possibly hazardous to aquatic communities. Due to potential and continuous release of carbendazim to aquatic systems, long term exposure to aquatic organisms should be addressed. ...
Traditionally aquatic toxicity studies examine the toxicity of a single chemical to an organism, while organisms in nature may be exposed to multiple toxicants. Given this is a more realistic exposure scenario in situ, the authors were interested in understanding the interactive toxicity of multiple metals to aquatic organisms. We performed a series of studies ...
Vegetated and shallow areas such as wetlands and salt marshes but also freshwater lakes and rivers have been identified as hotspots for Hg methylation. The presence of aquatic macrophytes, the predominant primary producers in shallow waters, play an important but still poorly understood role in the fate of Hg in in these environments. The present review focuses on the influences of macrophytes ...
Many contaminants are released into aquatic systems intermittently in a series of pulses. Pulse timing and magnitude can vary according to usage, compound‐specific physicochemical properties, and use area characteristics. Standard laboratory ecotoxicity tests typically employ continuous exposure concentrations over defined durations and thus may not accurately ...
Trenbolone is an androgen agonist used in cattle production and has been measured in aquatic systems associated with concentrated animal‐feeding operations. ...
“It also will help us understand how these forest systems will respond if we see changes in temperature or precipitation related to climate change,” says Dr. ...
Changes in percentage of forest cover can influence nutrient levels in aquatic systems and change abiotic conditions that may influence species. ...
However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. ...
Abstract A new, fully-automated, closed-chamber system was developed for measuring photosynthetic activity in aquatic plants, algae, or corals during immersion. ...
This study deals with the development of appropriate sustainable strategies for environmental-benign aquatic processing systems. In this regard, the interactions between the aquatic system and its environment are first defined. Second, the effect of environmental pollution decreasing the fish quality in the ...
Pinheiros River (Brazil) plays a pivotal role in supplying water to Billings Reservoir, which presents multiple uses (human drinking, energy generation, irrigation, navigation, fishing and leisure). An intense monitoring program was performed during the years 2007 and 2008 to find out whether on site flotation is a feasible solution or not for improving the water quality of this urban river, ...
The species diversity of phytoplankton is usually very high in wild aquatic systems, as seen in the paradox of plankton. Coexistence of many competitive phytoplankton species is extremely common in nature. ...
Abstract Limnological studies in two tropical Indian aquatic habitats showed that macroinvertebrate communities have greater diversity than other biotic communities present there. Sediment redox potential is found to be an important factor for alteration of macroinvertebrate communities in aquatic bodies. Anthropogenic activities have influenced the changing of sediment redox potential ...
Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. ...
Biologists and policy makers continue to seek environmental correlates of mercury bioavailability in aquatic ecosystems. In this study, we assessed the effects of drainage basin, habitat type, size class, and sex on mercury concentrations in the northern crayfish, Orconectes virilis (Hagen). ...
