The new IASPEI standards for determining magnitudes from digital data and their relation to classical magnitudes The new IASPEI standards for determining magnitudes from digital data and their relation to classical magnitudes

Why there is a need for measurement standards of magnitudes: In October 2005, the Commission on Seismic Observation and Interpretation of the International Association of Seismology and Physics of the Earth´s Interior (IASPEI) adopted the summary recommendations made by the IASPEI Working Group on Magnitudes on new measurement standards for widely used local, regional and teleseismic...

Spawning and nursery habitats of neotropical fish species in the tributaries of a regulated river Spawning and nursery habitats of neotropical fish species in the tributaries of a regulated river

This chapter provides information on ontogenetic patterns of neotropical fish species distribution in tributaries (Verde, Pardo, Anhanduí, and Aguapeí rivers) of the Porto Primavera Reservoir, in the heavily dammed Paraná River, Brazil, identifying key spawning and nursery habitats. Samplings were conducted monthly in the main channel of rivers and in marginal lagoons from October...

Salmonid intranuclear microsporidosis Salmonid intranuclear microsporidosis

Nucleospora salmonis is an intra-nuclear microsporidian parasite in the family Enterocytozoonidae (Docker et al. 1997). Prespore stages of the parasite were first observed among adult and then juvenile Chinook salmon (Oncorhynchus tshawytscha) by Elston et al. (1987) and Morrison et al. (1990), respectively in Washington, U.S.A. The microsporidian nature of the parasite was subsequently

The effects of climate-change-induced drought and freshwater wetlands The effects of climate-change-induced drought and freshwater wetlands

Drought cycles in wetlands may become more frequent and severe in the future, with consequences for wetland distribution and function. According to the Intergovernmental Panel on Climate Change (Intergovernmental Panel on Climate Change [IPCC], Managing the risks of extreme events and disasters to advance climate change adaptation, 2012.

Uncertainty Uncertainty

Management decisions will often be directly informed by model predictions. However, we now know there can be no expectation of a single ‘true’ model; thus, model results are uncertain. Understandable reporting of underlying uncertainty provides necessary context to decision-makers, as model results are used for management decisions. This, in turn, forms a mechanism by which groundwater...

Knowledge gained from video-monitoring grassland passerine nests Knowledge gained from video-monitoring grassland passerine nests

In the mid-1990s, researchers began using miniature cameras to videotape activities at cryptic passerine nests in grasslands.In subsequent years, use of these video surveillance systems spread dramatically, leading to major strides in our knowledge of nest predation and nesting ecology of many species.Studies using video nest surveillance have helped overturn or substantiate many long...
