/ Maintaining raptor populations is a primary objective of the legislation that designates the Snake River Birds of Prey National Conservation Area. Army training activities could influence habitat ...quality for raptors by changing the density, productivity, or behavior of their Townsend's ground squirrel (Spermophilus townsendii) prey. These changes could occur directly or as a result of changes in the vegetation available as food and cover for the ground squirrels. We assessed the effects of long-term tracking by armored vehicles by comparing 9-ha areas in sagebrush (Artemisia tridentata) -dominated shrubsteppe and bluegrass (Poa secunda) -dominated grasslands subjected to low-intensity tracking for approximately 50 years with others that had not been tracked. We did not detect any effect on ground squirrel population dynamics associated with long-term tracking. Although densities of adults and juveniles tended to be higher in the areas exposed to such tracking, we attribute this difference to other factors that varied spatially. To determine short-term (two-year) effects, we experimentally tracked two sagebrush and two grassland sites with an M-1 tank after animals had begun their inactive season. In the following two active seasons we monitored squirrel demography and behavior and vegetative characteristics on the experimentally tracked sites and compared the results with control sites. Although we experimentally tracked approximately 33% of the surface of each of four sites where ground squirrel densities were assessed, the tracking had a detectable effect only on some herbaceous perennials and did not influence ground squirrel densities or behavior significantly during the subsequent two active seasons. We conclude that tracking after the start of the inactive season is likely to influence ground squirrel demography or behavior only if vegetation cover is substantially changed by decreasing coverage of preferred food plants or increasing the coverage of annual grasses and forbs that are succulent for only a short time each year.KEY WORDS: Armored vehicle tracking; Ground squirrels; Spermophilus townsendii; Behavior; Vegetation; Population density effects
A survey of the mosquito fauna of Fort Campbell, Kentucky (Christian County, Kentucky, and Montgomery County, Tennessee) was conducted from May 1996 to May 1998. A total of 528 mosquito collection ...sites were sampled in the most comprehensive mosquito collection effort on the military installation since 1976. A total of 42 mosquito species were identified, including new locality records for 14 species.

Su producción y nivel científico es muy alto en un momento en que la geografía académica no estaba institucionalizada. Sus razonamientos, ante el mismo espacio geográfico, son distintos a la geografía de los profesores, ya que su objetivo es el conocimiento geográfico del terreno para su defensa o dominio. fr La géography militaire espagnole pendat le période 1819-1945 se présente comme une géographie appliquée, qui requiert une connaissance géographique générale pour l'appliquer aux besoins concernant le thème de la guerre. Le méthode pour V analyse de l'Espagne péninsulaire évolue à partir d'une étude relative aux bassins et versants hydrographiques jusqu'à une autre relative à l´aspect stratéqique, en pasant par les circonscriptions militaires. Sa production et son niveau scientifiques résultent d'un niveau élève à un moment où la géographique académique n'était pas institutionnalisée. Face au prope espace géographique, ses raissonnements diffèrent de la géographie des professeurs, puisque son objectif est celui de la connaissance géographique du terrain pour sa défense ou son emprise.
