Highlights research studies involving genetics and genomics, includes a glossary of terms on the subject, a directory of scientists involved in this type of work, and description of research facilities through which USGS carries out genetic studies
Describes the value of molecular biology genetic tools in enhancing the delineation of the genetic diversity and the effects of environmental degradation on living species. Links to research, which differentiated two species of sage-grouse.
Review of the size of breeding populations of Giant Canada geese by states in the Mississippi, Atlantic, Central, and Pacific flyways and the management problems caused by rapid increases of local breeding populations.
Proxy methods allow us to estimate ancient ocean temperatures but only if the method is calibrated using modern samples for which we measure the temperature. This is a proxy method using a sediment trap to collect planktonic foraminifera.
Overview of Klamath ecological research and links to USGS Klamath studies on ground water, nutrients, sediment oxygen demand, and fish response to water quality, sucker ecology, publications, bibliographies, and data.
