Twelve Years of Monitoring Phosphorus and Suspended-Solids Concentrations and Yields in the North Fork Ninnescah River above Cheney Reservoir, South-Central Kansas 1997-2008

The purpose of the article is to study the biography of B.M. Gordon as a successful security officer in the 1920-s and 1930-s. He worked his way up the career ladder from a junior investigator to the head of regional divisions – territorial bodies of the VChK/GPU/OGPU/NKVD and the legal residency of the INO GUGB of NKVD in Germany. Having started his chekist service in the Orel province, he served in the South – Central Asia, in the North – in Arkhangelsk province,in the capital of the USSR, and in the capital of Nazi Germany – Berlin. Gordon fought with the white guards and evicted the dispossessed peasants, controlled the Soviet military and gathered information about the armies of foreign countries; he managed to work at both Soviet and party work. Finally, the energetic work and successful career led Boris Moiseyevich Gordon to his death, when in 1937, J.V. Stalin decided to destroy completely all the former operational leadership of the state security agencies, replacing it with new personnel.

SummaryThe Violet-throated MetaltailMetallura baroniis a high altitude hummingbird endemic to south-central Ecuador currently considered globally ‘Endangered’. Here we present the first detailed assessment of its distribution, ecology and conservation. We first used a maximum entropy model (Maxent model) to create a predicted distribution for this species based on very limited species occurrence data. We used this model to guide field surveys for the species between April and October 2006. We found a positive relationship between model values and species presence, indicating that the model was a useful tool to predict species occurrence and guide exploration. In the sites where the metaltail was found we gathered data on its habitat requirements, food resources and behaviour. Our results indicate that Violet-throated Metaltail is restricted to the Western Cordillera of the Andes Mountains in Azuay and Cañar provinces of Ecuador, with an area of extent of less than 2,000 km2. Deep river canyons to the north and south, lack of suitable habitat, and potential interspecific competition in the east may limit the bird's distribution. The species occurred in three distinct habitats, includingPolylepiswoodland, the upper edge of the montane forest, and in shrubby paramo, but we found no difference in relative abundance among these habitats. The metaltail seems to tolerate moderate human intervention in its habitats as long as some native brushy cover is maintained. We found thatBrachyotumsp.,Berberissp., andBarnadesiasp. were important nectar resources. The ‘Endangered’ status of this species is supported due to its restricted distribution in fragmented habitats which are under increasing human pressures.
