aquatic invertebrates,   etc   ; global change; hydrology; rivers;     Show all 4 Subjects
Abstract:
... Temporary rivers (TRs) dominate global river networks and are increasing in occurrence and spatiotemporal extent. However, few studies have investigated the communities that establish after rewetting events (i.e. the end of the dry phase), when local hydrological conditions can shape the communities through species sorting, and the spatial connectivity of sites can also influence colonisation. Her ...

Abstract:
... The most parsimonious interpretation of our experimental findings (Bray 2019 ; Kefford 2022) is that the effect of experimental increases in salinity on stream macroinvertebrate communities, was altered by organisms from a high-salinity site. This interpretation is consistent with long-established and widely accepted ecological and ecotoxicological theory. The suggestion (Chessman 2022) that the i ...

Abstract:
... Land use change is one of the main factors affecting stream ecosystems since it modifies aquatic-terrestrial linkages and then structure and functioning as well. The aim of this study was to evaluate the effect of harvest on mountain afforested streams (Córdoba, Argentina).

Abstract:
... In aquatic invertebrate (e.g., daphnids and Artemia sp.) and zebrafish cultures, in ecotoxicological bioassays, or when addressing complex population‐level experimental designs, the counting of an organism's progeny is often required. This counting process is laborious, repetitive, and time‐consuming, potentially posing health hazards to the operators, and necessarily entailing a higher likelihood ...

Abstract:
... The use of imidacloprid and, to a lesser degree, other neonicotinoid insecticides is widespread in FL (and globally). The moderate to high water solubility and environmental persistence of neonicotinoids allows these compounds to readily enter, and be retained in, water resources where they may harm nontarget organisms and impact biological communities and associated trophic structures negatively. ...

Abstract:
... Nutrient imbalances in zooplankton are caused by the differences in elemental content of producers and the demand for elements in consumers, which alter the life-history traits in consumers. Changes in life-history traits are mediated through metabolic pathways that affect gene expression and the metabolome. However, less is known about proteomic changes to elemental-limitation in zooplankton. Her ...

We measured absolute (mg C or N) and relative a ...
