The frontal eyefields were discovered in 1874 by Ferrier and though considerable research has subsequently been done on physiological, anatomical and clinical as­ pects of this area in man and monkey (Smith, ’49), the specific role of the fron­ tal cortex in the complex organization of oculomotor activity is still virtually un­ known. Even the elucidation of anatom­ ical problems has made littl...

To mitigate erosion after fire, land managers often seed non-native grasses onto burned slopes. To assess how post-fire seeding affects plant recovery, we compared areas that were either unseeded or artificially seeded after high-intensity fire in a dry Abies grandis (Dougl.) Lindl. forest in the northeastern Cascades. Seeding with a mix of non-native grasses and a legume significantly reduced ...

A comprehensive taxonomic study is presented for the four genera and 286 species of the doryctine tribe Heterospilini occurring in Costa Rica. The tribe is represented almost entirely by the 280 species of the genus Heterospilus Haliday. Keys for identification of the genera and species are provided and the genera and species are described and illustrated. An interactive key to the species of H...

introduction: the occurrence and activity of mites in stored foods cause a variety of qualitative and quantitative damages, including reduction in the germinating power of the grains, bronchial asthma and allergic skin reactions. among the mites associated with stored products, species of order sarcoptiformes especially some species of astigmatina including the genera acarus, suidasia and tyrop...

Dynamic decisions arise in many applications including military, medical, management, sports, and emergency situations. During the past 50 years, a variety of general and powerful tools have emerged for understanding, analyzing, and aiding humans faced with these decisions. These tools include expected and multi-attribute utility analyses, game theory, Bayesian inference and Bayes nets, decisio...

In the most complete and first radiometrically dated Precambrian-Cambrian transition strata along the Khorbusuonka River in northern Siberia, a succession of fossilized traces of activity of the earliest infaunal animals has been identified. As supplemented by a similar record in Podolia, the Ukraine and elsewhere. This collection demonstrates that thus far all of the structurally identifiable ...
