CONDUCTIVITY TO RUST IN COFFEE UNDER DIFFERENT WOODEN AND FRUIT TREE INTERCROPPING SYSTEMS

The coffee intercropping with fruit and wooden species of economic value has been presented as a viable alternative for coffee cultivation in order to mitigate adverse environmental conditions for coffee trees, among other factors. Adapting the crop management to the new conditions stablished by the system is fundamental to obtain success on intercropping. One of the most serious diseases for the crop is the rust caused by Hemileia vastatrix., which may have its severity increased in function of the microclimate conditions provided by the trees. In this sense, the disease behavior under different intercropping systems and consequent different need to adapt the control measures when compared to the cultivation in full sun should be investigated. The present study was conducted aimed to verify the impact of tree systems composed by three wooden species, Cedar (Acrocarpos fraxinifolius), African mahogany (Khaya ivorensis ), Teak (Tectona grandis ) and two species of fruit trees, avocado (Persea Americana) and macadamia (Macadamia integrifolia) planted in different spacing over the occurrence and evolution of rust.It was possible to observe that coffee rust began to progress in the coffee plants from the month of February reaching a peak in September in all the treatments. Differences were observed in the progress curves of the disease, especially in the species that presented larger canopy such as avocado. Further studies are suggested with the purpose of establishing the microclimatic changes provided by the cultivation of different wooden and fruit species in intercropping with coffee, according to the dynamics of the climate and their development

VIABILIDADE FINANCEIRA DA PRODUÇÃO DE CAFÉ IRRIGADO EM REGIÕES APTAS AO CULTIVO NÃO IRRIGADO

Due to new economic order, agricultural business is of the same complexity, importance and dynamics of other sectors of theeconomy, requiring farmers to have a new outlook on how to run their business. Thus, it becomes necessary to economicaly analyze theactivity you begin to know the details and to use the production factors intelligently and cost efficiently. Therefore, this study aimed to estimatethe cost of production of arabica coffee (Coffea arabica L.) irrigated with a central pivot in the region of Lavras, MG. The experimental designwas randomized blocks with six treatments and three repetitions. The treatments consisted of water levels applied according to thepercentages of crop coefficients values (Kc), currently used by irrigators in the region of Lavras, and evapotranspiration reference (ET0),that is: Tr1 = 0; Tr2 = 60%KcET0, Tr3 = 80%KcET0, Tr4 = 100% KcET0, Tr5 = 120% KcET0 e Tr6 = 140%KcET0 . For the process ofestimating the cost of production, conceptualized as the sum of values of all resources and operations used in the production process of theactivity, we used the calculation of depreciation and alternative cost. The average productivity achieved with the treatments was 29.31, 39.51,51.12, 60.65, 63.82 and 74.84 bags per hectare for Tr1, Tr2, Tr3, TR4, TR5 and Tr6 respectively. Considering the price of a bag of coffee at$250.00, the economic analysis showed that, at this price level, irrigated coffee production is economically viable, and irrigation management,with water replacement calculated based on 100$ 250,00, asituação econômica analisada mostrou que, neste nível de preço, é economicamente viável a produção de café irrigado, e o manejo dairrigação, com a lâmina de reposição calculada com base em 100% do valor de Kc, proporcionou maiores lucros

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.
