Morphologic characterization and evaluation of the productivity of nine rootstocks of rose bush (rosa spp.)

In Brazil, garden and cut rose bushes are propagated through cuttings or grafting. The rootstocks used in most of the traditional areas of cultivation are not identified, being known just by the vulgar name. There is not any information in the literature on the morphologic characteristics, nor about the productivity of different cultivars on the rootstocks available in Brazil. The objective of this work was to characterize and determine productivity of nine rootstocks (Rosa multiflora 'Paulista'; R. multiflora 'Japones'; R. multiflora 'Iowa'; R. multiflora 'Kopmans'; R. indica 'Mayor'; R. indica x multiflora; R. sp. 'Natual Brier'; R. manetti and R. canina 'Inermis') grafted with 'Versilia' and 'Tineke' scions. Morphologic studies were undertaken to characterize branches of adult plants to determine shape and dimensions of the leaf; number of prickles/15 cm of stem; vigor of the stems; incidence of Diplocarpon rosae (blackspot) and coloration of the leaf. The productivity (number of commercial flowers/plant/month) was evaluated for 6 months (October, 2000 to March, 2001), in the city of Andradas, Minas Gerais State, located at 1251 meters above sea level. Since there was significant difference in just two months for both rootstocks, 'Tineke' and 'Versilia', no rootstocks could be considered inadequate. Nonetheless, in general, the rootstocks that showed a better performance with 'Tineke' were, R. multiflora 'Kopmans' and R. manetti and with 'Versilia', R. multiflora 'Kopmans' and Rosa sp. 'Natual Brier'.

First telemetry study of bush dogs: Home range, activity and habitat selection

Context The bush dog (Speothos venaticus) is difficult to observe, capture, and study. To date, indirect evidence and opportunistic field observations have been the primary sources of information about the species' ecology. Field data are urgently needed to clarify the species' ecological requirements, behaviour and movement patterns. Aims The present study uses 13 months of telemetry data from a group of bush dogs to begin to address questions about area requirements, habitat preferences and movement patterns of this difficult-to-study species. Methods We tracked a group of bush dogs (two adults, one juvenile, four young) in an area of intact and altered Cerrado (woodlandsavanna biome) in eastern Mato Grosso, Brazil (Nova Xavantina District). Key results The group had a total home range of 140km2 (fixed kernel 95%), with smaller seasonal 'subareas' (areas used for 12 months before moving to another area, with repetition of some areas over time) and demonstrated a preference for native habitats. Conclusions The bush dog's home range is greater than that of other canids of the same size, even correcting for group size. Patterns of seasonal movement are also different from what has been observed in other South American canids. Implications From our observations in the Brazilian savanna, bush dogs need large tracks of native habitat for their long-term persistence. Although the present study is based on a single pack, it is highly relevant for bush dog conservation because it provides novel information on the species' spatial requirements and habitat preferences. © 2012 CSIRO.

Ejes estratégicos de la seguridad hemisférica en los gobiernos de George W. Bush y Barack Obama

The paper approaches the U.S. perceptions about the sources of insecurity from Latin America, considered a low risk area and priority of its foreign policy. El análisis se concentra en la evaluación de las amenazas y desafíos a sus intereses estratégicos y las modalidades de actuación privilegiadas en la esfera regional, en que se verifican coincidencias entre las administraciones Demócratas y Republicanas en la adopción de un liderazgo con prerrogativas clasificatorias sobre los tipos de régimen político, con una agenda concebida como promoción de la convergencia hemisférica de democracias y economías liberales. The analysis focuses on assessing the threats and challenges to its strategic interests and privileged modes of action at the regional level, which verifies similarities between Republican and Democratic administrations in taking a leadership prerogatives qualifiers on the types political regime, with an agenda designed as promoting hemispheric convergence of liberal democracies and economies. En ese contexto, cabe destacar la prioridad atribuida a los países de la Alternativa Bolivariana para las Américas (ALBA) como eje opositor de sus políticas. In this context, include the priority given to the countries of the Bolivarian Alternative for the Americas (ALBA) as the linchpin of his political opponent.
