(2013-01-11)Abstract Background This article aims to discuss the incorporation of traditional time in the construction of a management scenario for pink shrimp in the Patos Lagoon estuary (RS), Brazil. To ... -
Ability to alter song in two grassland songbirds exposed to simulated anthropogenic noise is not related to pre-existing variability.
(Taylor and Francis, 2018)Organisms encounter noise naturally in the environment. However, increasing prevalence of human-caused noise seems to be resulting in behavioural changes in many animals that can affect survival and reproduction. Not all ... -

Air-Sea CO2 flux estimates in stratified Arctic coastal waters: How wrong can we be?
(AGU, 2019-01-03)Summer near-surface seawater sampling in the Canadian Arctic revealed potential for significant errors (nearly 0.1 μmol·(m-2 s -1)) in CO2 fluxes calculated from measured air-sea CO2 gradients. River runoff and sea ice ... -
Algae, Cyanobacteria and Water Quality
(Agriculture and Agri-Food Canada, 2002-03)Algae and cyanobacteria are tiny organisms that occur naturally in saltwater and freshwater. Individual organisms can often only be seen under a microscope, although with some species , individuals can join together to ... -
America's animal factories: how states fail to prevent pollution from livestock waste
(Natural Resources Defense Council, 1998)Factory farms, which mass-produce animals in assembly-line fashion, have harmed aquatic life, human health and ecosystems across the nation. As industrial-sized farms stagger under the vast burden of manure they are ... -
