Diversidad morfológica y variación isoenzimática de maíces nativos del altiplano centro-oriente del estado de Puebla.
Provedor de dados: 32
Autores: Hortelano Santa Rosa, René.
La presente investigación tuvo por objetivo cuantificar y analizar la diversidad genética (a nivel morfológico e isoenzimático) presente actualmente entre poblaciones nativas de maíz (Zea mays L.), cultivadas en la región Centro-Oriente del Altiplano del estado de Puebla, así como establecer las relaciones de similitud que aquellas presentan con las razas reportadas para el área. El trabajo se desarrolló en dos etapas: la primera consistió en la evaluación, en tres localidades, de 134 poblaciones nativas, seis accesiones „tipo‟ de las razas Cónico, Cónico Norteño, Palomero Toluqueño, Chalqueño y sus variantes Chalqueño Crema y Chalqueño Palomo y cuatro variedades comerciales recomendadas para la zona. El diseño empleado fue un látice simple 12x12. Durante...

The Dynamics of Social Capital and Conflict Management in Multiple Resource Regimes:  A Case of the Southwestern Highlands of Uganda
Provedor de dados: 7
Autores: Sanginga, Pascal C; International Centre for Tropical Agriculture -CIAT; p.sanginga@cgiar.org; Kamugisha, Rick N; Africa Highlands Initiative; rnkamugisha@yahoo.com; Martin, Andrienne M; Natural Resources Institute; A.M.Martin@greenwich.ac.uk.
Increasingly, social capital, defined as shared norms, trust, and the horizontal and vertical social networks that facilitate coordination and cooperation for mutually beneficial collective action, is seen as an important asset upon which people rely to manage natural resources and resolve conflicts. This paper uses empirical data from households and community surveys and case studies, to examine the role, strengths, and limits of social capital in managing conflicts over the use and management of natural resources. We inventoried over 700 cases ranging from conflicts between multiple resource users to supra-community conflicts between local communities concerns for better livelihoods and national/international concerns for environment conservation....

Adoption of Improved Wheat Technologies by Small-Scale Farmers in Mbeya District, Southern Highlands, Tanzania
Provedor de dados: 31
Autores: Mussei,   Ahaz; Mwanga,   Judicate; Mwangi,   Wilfred; Verkuijl,   Hugo; Mongi,   Rose; Elanga,   Anthony.
This study was conducted to gain an understanding of how small-scale farmers in Mbeya District have adopted improved wheat technologies promoted by the wheat research program at MARTI-Uyole. The specific objectives were to assess farmers’ wheat management practices, determine the technical and socioeconomic factors affecting the adoption of improved wheat technologies, and draw implications for research, extension, and policy. A purposive multistage sampling procedure was used to select 202 farmers, 160 from Tembela Division and 42 from Isangati Division, which are two important wheat-growing areas in Mbeya District. Primary data were collected using structured questionnaires and supplemented by secondary information obtained from MARTI-Uyole. Juhudi was...

Emerging supply chains of indigenous pork and their impacts on small-scale farmers in upland areas of Vietnam
Provedor de dados: 31
Autores: Huong,   Pham Thi Mai; Hau,   Nguyen Van; Kaufmann,   Brigitte; Valle-Zarate,   Anne; Mergenthaler,   Marcus.
Rising incomes, urbanization and globalization have been leading to profound changes in the consumption habits of an increasing number of people in developing and transition countries, particularly in Asia. These changes are linked to increasing concerns that small-scale farmers are becoming marginalized in new market set-ups. On the back-ground of these developments we analyze how growing demand for indigenous pork – considered a specialty product among consumers in Vietnam – impacts through newly emerging supply chains on small-scale farmers in upland areas. We analyze supply chains and price transmission as well as compare the impact of marketing institutions on the economics of primary production. Results of market surveys show that carcasses of...

Distribution pattern of anurans from three mountain complexes in southeastern Brazil and their conservation implications
Provedor de dados: 42
Autores: NEVES,MATHEUS O.; PEREIRA,ELVIS A.; SUGAI,JOSÉ LUIZ M.M.; ROCHA,SABINE B. DA; FEIO,RENATO N.; SANTANA,DIEGO J.
ABSTRACT Biogeographic tools support spatial distribution pattern hypotheses and help to determine priority areas for conservation. Our aim was to verify biogeographic patterns for anurans in three mountain complexes in southeastern Brazil, as well as to discuss the status of species conservation recorded and the biogeographical units evaluated. We selected 16 areas distributed in the Serra da Mantiqueira complex, south of Serra do Espinhaço and Serra da Canastra. We used the occurrence (geographic coordinates) of each species in the localities to determine areas of endemism applying the Endemicity Analysis method. We also tested whether similarity between areas was explained by geographic distance (Multiple Regression on distance Matrices-MRM). The Serra...

Diet of the toad Rhinella icterica (Anura: Bufonidae) from Atlantic Forest Highlands of southeastern Brazil
Provedor de dados: 49
Autores: Sabagh,Leandro Talione; Carvalho-e-Silva,Ana Maria Paulino Telles; Rocha,Carlos Frederico Duarte.
In this study, we present some information of the regarding throphic niche from the anuran toad Rhinella icterica living in high altitudes above 2000 m a.s.l. from a habitat of the Atlantic Forest Biome - the Altitude Fields in the Itatiaia National Park. We found 150 prey items in toad stomachs, belonging to five prey types, as well as skin remains and some remains of plant material. The index of relative importance indicated that most important prey types were beetles and ants, these last composing 70% of the diet numerically and the trophic niche breadth (B) was 1.81. The relatively low diversity of prey types we recorded in the diet of R. icterica of Itatiaia and numerically dominated by ants suggests some preference for this item. We do not found...
