The genesis of the northern Kettle Moraine, Wisconsin
Interpreting past glacial dynamics from the glacial record requires that the depositional environments of glacial sediments and landforms be understood. In the case of interlobate deposits, models that incorporate various components of pro, supra and subglacial deposition have been developed and tested in the northern Kettle Moraine (nKM), Wisconsin; a large interlobate deposit that formed betw...
متن کاملHybridization and speciation in centrarchids
Open any field guide and you will find a list of species, with brief descriptions of how to distinguish each species from other closely related species. Such field guides convey an impression of stable, cleanly delineated groups. This can lead to significant confusion when our orderly Linnean categories run into the sometimes messy reality of biology. For example, consider the recent controvers...
متن کاملMoraine pebbles and boulders yield indistinguishable 10Be ages: A case study from Colorado, USA
Cosmogenic exposure dating of moraines during the last two decades has vastly improved knowledge on the timing of glaciation worldwide. Due to a variety of geologic complications, such as moraine degradation, snow cover, bedrock erosion and isotopic inheritance, samples from multiple large boulders (>1– 2 m) often lead to the most accurate moraine age assignments. However, in many cases, large ...
متن کاملGenetic Identification of Spotted Owls, Barred Owls, and Their Hybrids: Legal Implications of Hybrid Identity
Recent population expansion of Barred Owls ( Strix varia) into western North America has led to concern that they may compete with and further harm the Northern Spotted Owl ( S. occidentalis caurina), which is already listed as threatened under the U.S. Endangered Species Act (ESA). Because they hybridize, there is a legal need under the ESA for forensic identification of both species and their...
متن کاملTiming of the last deglaciation in Lithuania
Boulders from the Grūda Moraine, which is associated with the maximum extent of the Scandinavian Ice Sheet (SIS) during the last glaciation, and the Baltija (also referred to as the South Lithuanian), the Middle and North Lithuanian moraines, which are associated with recessional stages of the SIS, were sampled for surface exposure dating using Be. By combining these data with existing radiocar...
