Comparing the acute toxicity (48–96‐h) of sodium chloride (NaCl) and/or synthetic marine salt laboratory exposures of freshwater invertebrates to the salinity in unconventional gas produced waters from coal bed methane and shale gas extraction, and how other major ions (Ca2+, K+, Mg2+, CO32–, HCO3–, SO42–) can influence the toxicity of Na+ and Cl– ions

Population response to connectivity restoration of high elevation tropical stream reaches in Hawai'i
Abstract Tropical island streams are heavily impacted by water withdrawals to the detriment of native ecosystems. Freshwater fauna in the tropics often exhibit diadromous life‐history strategies, requiring hydrologic connectivity between upstream and nearshore habitats.

Density and gender segregation effects in the culture of the caridean ornamental red cherry shrimp Neocaridina davidi Bouvier, 1904 (Caridea: Atyidae) [PDF]
The effect of density on growth, sex ratio, survival, and biochemical composition of the red cherry shrimp, Neocaridina davidi Bouvier, 1904, was studied to determine optimum rearing conditions in this ornamental species.

Abstract Tropical freshwater invertebrate species are becoming extinct without being described, and effective conservation is hampered by a lack of taxonomic and distribution data. DNA metabarcoding is a promising tool for rapid biodiversity assessments that has never been applied to tropical freshwater invertebrates across large spatial and taxonomic ...

Effects of river regulation on aquatic invertebrate community composition: A comparative analysis in two southern African rivers. [PDF]
This study compared aquatic invertebrate communities between a regulated and unregulated river and sought to determine whether the largest inland lake of the region, which receives water from both rivers, resembles the aquatic invertebrate communities of either river.

Development of a flow‐sensitive macroinvertebrate index for Australian rivers
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.

Abstract Recent studies showed the potential of stable isotopes of the macronutrient calcium (δ44/40Ca) and nonessential strontium (δ88/86Sr) as new trophic level indicators in terrestrial vertebrates and marine teleost fishes. In this study, we tested whether similar Ca and Sr isotopic fractionation trends existed in macroinvertebrate‐dominated stream

Extended Parental Care in the Freshwater Shrimp Genus Dugastella Bouvier, 1912 (Decapoda, Atyidae, Paratyinae) [PDF]
5 páginas, 1 figura.Parental care and extended parental care are known behaviours in decapod crustaceans (see Thiel, 2000, 2003). While parental care before hatching, which involves incubation of the eggs (carrying, cleaning, and aeration) by females ...

Considering the environmental impacts to rivers caused by the exploitation of water resources and the consequences of these impacts upon fauna, the objective of this study was to evaluate the population biology of the shrimp Atya scabra (Leach, 1816) in ...
