Determinación y estudio de sustratos y fertirrigación en la producción de plantas cítricas certificadas. Colegio de Postgraduados
Contreras Fuentes, Griselda Magdalena.
En México, la producción de plantas cítricas certificadas se realiza desde hace 10 años, bajo normas fitosanitarias para evitar la diseminación de plagas y enfermedades cuarentenarias. Se identificaron los factores con potencial de mejoramiento en estos sistemas de producción, mediante entrevistas a investigadores nacionales e internacionales, viveristas y productores de cítricos. Con base en ello, se seleccionaron y caracterizaron los sustratos fibra de coco (Fc), tepezil (T) y composta de bagazo de cítricos (C) y se determinó el uso de la Mezcla 1= Fc 35%+T 25%+C 40% y Mezcla 3= Fc 55%+T 25%+C 20%. Se evaluó el desarrollo de los portainjertos Citrus volkameriana Ten. & Pasq. y citrumelo Swingle (Poncirus trifoliata Macf. x Citrus paradisi Raf.) en...

Diagnosis of directed pollination services in apple orchards in Brazil. Repositório Alice
ROSA, J. M. da; ARIOLI, C. J.; BLOCHTEIN, B.; AGOSTINETTO, L.; GRUTZMACHER, A. D.; BOTTON, M..
The pollination services performed by Apis mellifera are essential for the high-quality apple production. The aim of this study was to obtain information about the pollination services used in the municipalities of Vacaria-RS e São Joaquim-SC, the main apple-producing regions in Brazil. Semi-structured interviews were conducted with apple growers and technicians responsible for the orchards during 2013 and 2015. The obtained information was: a) cropping systems; b) use of pollination services; c) number of hives per hectare during flowering; d) renting value of hives; e) mortality of colonies; f) agrochemicals used on flowering; g) presence of native bees on flowering. In Vacaria and São Joaquim, respectively, 70% and 68.6% of the apple growers use the...

Evaluating the use of local ecological knowledge to monitor hunted tropical-forest wildlife over large spatial scales Ecology and Society
Peres, Carlos A.; School of Environmental Sciences, University of East Anglia, Norwich, UK; C.Peres@uea.ac.uk.
Monitoring the distribution and abundance of hunted wildlife is critical to achieving sustainable resource use, yet adequate data are sparse for most tropical regions. Conventional methods for monitoring hunted forest-vertebrate species require intensive in situ survey effort, which severely constrains spatial and temporal replication. Integrating local ecological knowledge (LEK) into monitoring and management is appealing because it can be cost-effective, enhance community participation, and provide novel insights into sustainable resource use. We develop a technique to monitor population depletion of hunted forest wildlife in the Brazilian Amazon, based on the local ecological knowledge of rural hunters. We performed rapid interview surveys to estimate...

Factors that influence the use of contract farming by southern Chilean farmers Ciencia e Investigación Agraria
Morales,Liliana; Echeverría,Rodrigo; Barrera,María del V.
Unlike in the central zone of Chile, the use of contract farming (CF) is uncommon in the southern regions of the country, and few studies have attempted to explain this situation. The objective of this study was to analyze the factors that influence the use of CF in southern Chile. The methodology consisted of two approaches: a quantitative approach, wherein a multinomial logit model was applied to data obtained from questionnaires completed by 384 southern producers, and a qualitative approach that included in-depth individual interviews with professionals, officials of public institutions, and producer focus groups. The main results show that producers with high educational levels, large farms, and production oriented toward the export market who are...

Impact of fuel costs on high-latitude subsistence activities Ecology and Society
Brinkman, Todd; Institute of Arctic Biology, University of Alaska Fairbanks; tjbrinkman@alaska.edu; Kelly, James; Council of Athabascan Tribal Governments; jkelly@catg.org; Vandyke, Michelle; Council of Athabascan Tribal Governments; mvandyke@catg.org; Firmin, Andrew; Council of Athabascan Tribal Governments;; Springsteen, Anna; Scenarios Network for Alaska and Arctic Planning, University of Alaska Fairbanks; alspringsteen@alaska.edu.
Most rural residents in Arctic communities rely on motorized transportation to hunt, fish, trap, and gather subsistence resources. Although these technologies have created advantages, one significant disadvantage is that peoples’ ability to meet their nutritional and cultural needs now depends on consistent opportunities for wage employment and availability of affordable fuel. Recent qualitative research suggested that rising fuel prices have disrupted subsistence lifestyles in the Arctic. Our objectives were to collaborate with subsistence users in rural Alaskan communities to quantify how rising fuel costs have impacted subsistence activities and explore ways local residents may adapt to the trajectory of change. We conducted interviews with...

Lack of evidence for the presence of macaws of the Anodorhynchus genus in the Colombian-Brazilian river basin of the Vaupés Hornero
López-Lanús,Bernabé; Laverde,Oscar; Omena Jr.,Reynier; Olarte,Luis G..
It is generally understood that the Anodorhynchus genus of macaws does not spread north of the Amazon River. However, recent published information suggests that the endangered Hyacinth Macaw Anodorhynchus hyacinthinus may occur in the region of the Papurí River, lower Vaupés, in Amazonian Colombia. This information is hypothetical, based on old reports and observations with imprecise geographical data. Our objective was to confirm the presence of macaws of the genus Anodorhynchus in the lower Vaupés, Colombia, and in nearby Negro River, Brazil. We carried out fieldwork and interviews from September 2004 to July 2005, but we failed to locate the species. Notwithstanding, we received information from 8% of the interviewed members of local ethnic groups...

Remote electronic monitoring and the landing obligation - some insights into fishers' and fishery inspectors' opinions ArchiMer
Plet-hansen, Kristian S.; Eliasen, Soren Q.; Mortensen, Lars O.; Bergsson, Heiorikur; Olesen, Hans J.; Ulrich, Clara.
The European fisheries management is currently undergoing a fundamental change in the handling of catches of commercial fisheries with the implementation of the 2013 Common Fisheries Policy. One of the main objectives of the policy is to end the practice of discarding in the EU by 2019. However, for such changes to be successful, it is vital to ensure stakeholders acceptance, and it is prudent to consider possible means to verify compliance with the new regulation. Remote Electronic Monitoring (REM) with Closed-Circuit Television (CCTV) has been tested in a variety of fisheries worldwide for different purposes and is currently considered as one possible tool to ensure compliance with a European ban on discards. This study focuses on Danish fishery...

Why do fishermen discard? Distribution and quantification of the causes of discards in the Southern Bay of Biscay passive gear fisheries. ArchiMer
Morandeau, Gilles; Macher, Claire; Sanchez, Florence; Bru, Noelle; Fauconnet, Laurence; Caill-milly, Nathalie.
In the context of the Common Fisheries Policy reform, the need for decreasing discards has been highlighted in discussions on the implementation of a discard ban. While most of the research has focused on the quantification of discards by species and métier, identification and quantification of the causes of discards have received little attention. This study presents the results of on-board surveys conducted in the Southern Bay of Biscay fleets of netters and longliners. A large variability of discards was observed. It is also shown that in these passive gear fisheries the main reasons for discarding put forward by fishermen are, firstly, market-related and, secondly, quality-related; discards related to the application of regulations are minor. The...
