Title A name given to the resource Darwin, and the role of theories in evolutionary thinking Darwin y el papel de las teorías en el pensamiento evolutivo Creator An entity primarily responsible for making the resource GERMÁN MANRÍQUEZ Description An account of the resource The section 'Special Features' is dedicated to share with its readers thematic works about natural history, ecology and evolution. In this introduction we focus on the role that theories play in the construction of evolutionary thinking. First, we briefly show the importance of Lamarck's work in the context of pre-Darwinian theories about organic evolution. Then, the main components of the Darwinian theoretical core and its postDarwinian extensions are thoroughly discussed. Finally the essays following this introduction in the present issue are summarized.La sección 'Temas especiales' está dedicada a compartir con sus lectores trabajos temáticos sobre historia natural, ecología y evolución. En esta introducción nos centraremos en el papel que juegan las teorías en la construcción del pensamiento evolutivo. En primer lugar, se mostrará brevemente la importancia de la obra de Lamarck en el contexto de las teorías predarwinianas sobre evolución orgánica. Luego se discutirán en detalle los principales componentes del núcleo teórico del darwinismo así como sus extensiones postdarwinianas. Finalmente se resumen los ensayos que siguen a la presente introducción.

Title A name given to the resource La cadena de valor como factor esencial para el desarrollo de las empresas Creator An entity primarily responsible for making the resource Janeth Moreira de Vélez Description An account of the resource El análisis de la cadena de valor es una herramienta moderna, útil para establecer los puntos fuertes y débiles en las actividades de las empresas, pues basa su accionar en un análisis interno detallado de los distintos 'centros de actividad', y dentro de cada uno de ellos, de las actividades más representativas que despliegan las empresas en el día a día. La aplicación de ésta herramienta es completamente universal, y no se circunscribe solamente dentro de las grandes empresas extranjeras y/o nacionales, motivo por el que, la Dirección de la Carrera de Administración de la Facultad de Ciencias Administrativas y Económicas de la Universidad Técnica de Manabí ha emprendido en un proyecto de investigacion titulado 'Identificación y Análisis de la Cadena de Valor de los negocios agroindustriales que aportan mayoritariamente al PIB de la provincia de Manabi. Período 2008-2011 ' con la colaboración de los docentes y estudiantes de los últimos niveles de la carrera, a efectos de demostrar también, la utilidad del análisis de la cadena de valor como factor fundamental para el desarrollo de la agroindustria en Manabi.

Title A name given to the resource Ecologia política: Guerreiro Ramos e Fritjof Capra Political ecology: Guerreiro Ramos and Fritjof Capra Creator An entity primarily responsible for making the resource Sérgio Luís Boeira Description An account of the resource Este ensaio tem por objetivo contribuir com a articulação de um campo de pesquisa trans-disciplinar, a ecologia política, por meio da síntese comparativa de duas obras: A Nova Ciência das Organizações, de Alberto Guerreiro Ramos (1981), e O Ponto de Mutação, de Fritjof Capra (1982). A hipótese central deste trabalho é que os autores, apesar de suas formações acadêmicas muito diferentes, chegaram a resultados muito semelhantes nestas obras, a partir de um mesmo paradigma emergente. Dado o contexto ainda difuso do pensamento ambientalista, estes livros podem ser considerados clássicos da ecologia política.The aim of this essay is to contribute with the articulation of a trans-disciplinary research field, political ecology, by means of the comparative synthesis of two works: 'The New Science of Organizations' by Alberto Guerreiro Ramos (1981), and 'The Mutation Point', by Fritjof Capra (1982). The central hypothesis of this article is that both authors, although with very different academic background, get to very similar conclusions in these two works, under the same emergent paradigm. Given the still diffuse context of environmentalist thought these books may be considered classics of political ecology.

Title A name given to the resource Agricultura familiar no Brasil: uma revisão teórica Creator An entity primarily responsible for making the resource Luciana Cristina Moura Zangaro Description An account of the resource O presente trabalho teve por objetivo fazer uma revisão teórica sobre o tema da agricultura familiar. Para isso, buscamos as diferentes análises feitas por vários autores, no período que vai de 1960 até os dias atuais, de acordo com o contexto em que o tema estava sendo discutido. Partimos do debate polêmico das teses feudalismo x capitalismo, passando pela questão da produção familiar na década de 70 e 80 onde foram privilegiados alguns aspectos estruturais como o desenvolvimento do capitalismo no campo, o processo de acumulação de capital e os reflexos das transformações capitalistas para a produção familiar. Em seguida o debate sobre a 'funcionalidade' da pequena produção que gerou muitas controvérsias, e, finalmente, uma síntese das análises feitas à partir dos anos 90 sobre a agricultura familiar, enfocando o papel e os espaços desta no sistema capitalista.

Title A name given to the resource Alterações químicas em solo submetido a diferentes formas de manejo do cafeeiro Creator An entity primarily responsible for making the resource Theodoro V. C. A., Alvarenga M. I. N., Guimarães R. J., Souza C. A. S. Description An account of the resource A difusão de pacotes tecnológicos que preconizam o uso de altas dosagens de adubos químicos e o controle de pragas e doenças, como métodos para manter o potencial produtivo das lavouras, obriga o produtor a utilizar aplicações sistemáticas de fertilizantes inorgânicos e pesticidas, o que vem afetando a sustentabilidade do agroecossistema cafeeiro, gerando uma total dependência de insumos industrializados. O objetivo deste estudo foi relacionar as mudanças nas características químicas, físicas e microbiológicas de um Latossolo Vermelho distrófico (LVd), da região de Santo Antônio do Amparo (MG), sob agroecossistemas de produção de 'café orgânico', 'em conversão' e 'convencional', em relação a um fragmento de mata nativa. Em duas fazendas sob influência de condições similares de clima e relevo, apresentando o mesmo cultivar (Acaiá IAC474-19) e idade da lavoura (cinco anos), foi realizado um levantamento de dados por um período de um ano. O solo foi amostrado na profundidade de 0-20 cm, em duas épocas (julho/1999 e dezembro/1999). A análise de componentes principais permitiu uma visualização conjunta das características que mais influíram no comportamento do solo dos diferentes sistemas estudados. De modo geral, as formas de manejo para produção de café orgânico, em conversão e convencional, proporcionaram aumentos na fertilidade do solo, quando comparados com a condição do solo do fragmento de mata nativa. No agroecossistema de produção de café orgânico, foram obtidas maiores alterações das características químicas em relação ao convencional; houve incrementos no pH e nos valores de Ca, Mg, K, P, Zn, B, CTC do solo, soma de bases, saturação por bases e diminuição do Al trocável.

Title A name given to the resource Recursos florestais no assentamento 12 de outubro (Horto Vergel), Mogi-Mirim, SP Forestry resources at the settlement '12 de outubro' (Horto Vergel), Mogi Mirim, SP Creator An entity primarily responsible for making the resource Maristela Simões do Carmo, Livia Atauri Miranda Description An account of the resource Este trabalho objetivou contribuir para a caracterização dos usos de recursos florestais tomando como estudo de caso o assentamento Horto Vergel em Mogi-Mirim, Estado de São Paulo. A metodologia utilizou como ferramenta de coleta de dados entrevistas semiestruturadas com os agricultores assentados, além da observação direta no campo. Os agricultores entrevistados foram aleatoriamente amostrados, representando 42,63% da população total do assentamento. Os resultados indicaram que a grande maioria dos agricultores do assentamento 12 de outubro (81,4%) utilizava recursos florestais em alguma escala, porém eles não o faziam de forma adequada, o que poderá levar à exaustão desses recursos em médio prazo. Tais recursos são mobilizados para a produção de carvão, madeira, venda de tocos de eucalipto, produção de óleo essencial e muito pouco de atividades apicultoras e coleta de sementes para produção de mudas. Os recursos florestais, de modo geral, entre as possibilidades estratégicas, ainda são vistos como secundários e coadjuvantes, ou até antagônicos, para se atingirem os objetivos de permanência no lote.The present work aims to contribute to the characterization of forest resource use in rural settlements, taking as the case of study the settlement Horto Vergel in Mogi-Mirim, São Paulo State. For data collection, partially structured interviews were used, along with direct observation in the field. The farmers interviewed were randomly sampled and represented 42,63% from the total population of the settlement. The results obtained indicated that most farmers interviewed in the Settlement '12 de Outubro' (81,4%) use forestry resources on some scale, but not in a proper way, which can lead to the depletion of these resources in a medium term. Such resources are used for coal and wood production, as well the selling of eucalyptus stumps, essential oil production from leaves, incipient beekeeping activities and seed collection for tree seedling production. In general, forest resources are seen as secondary and supporting, or even antagonist elements for abidance in the land.

Title A name given to the resource Aspectos de la relación entre Thalurania Furcata Colombica (Aves Trochilidae) y las flores en que liba, en un bosque subandino Aspectos de la relación entre Thalurania Furcata Colombica (Aves Trochilidae) y las flores en que liba, en un bosque subandino Creator An entity primarily responsible for making the resource Ayala R. Ana Victoria Description An account of the resource El mayor nivel de coadaptación ave nectarívora-flor conocido hasta el momento, se ha logrado en los Trochilidae (VAN DER PIJL & DODSON,1969; FEINSINGER et al., 1979) ; tanto, que se ha hablado de flores adaptadas a la polinización por una especie particular de colibrí, y de colibríes que dependen para su alimentación de una sola clase de flor (SNOW & SNOW, 1980).Los factores principales que afectan la selección de alimento por parte de los colibríes están relacionados con: hábitat y estratificación de la vegetación (STILES & VVOLF,1970; FEINSINGER & CoLWELL, 1978), distribución espacial y características de las flores (FEINSINGER & COLYVELL,1978; FEINSINGER et al., 1979), distribución temporal del alimento (WOLF et al., 1976), morfología del pico del ave (FEINSINGER & COLWELL, 1978; STILES, 1978 a; FEINSINGER et al., 1979), tamaño del cuerpo (VVOLF et al., 1976), 'disco de sustentación del ala' (wing disc loading) y, finalmente, la energía que el colibrí requiere para sustentarse en el aire (EPTING & CASEY, 1973; WOLF et al., 1976). Colombia está incluida en el área central de evolución de los Trochilidae (SNOW & SNOW,- 1980) y posee numerosas especies así como riqueza de hábitats ocupados por ellos. Al igual que trabajos anteriores (SNOW & SNOW, 1980; MURCIA, 1983), el presente aporta al conocimiento de la ecología de los colibríes en este país; especificamente, trata algunos aspectos de la interacción Thalurania furcata colombica-flor proveedora de alimento en un Bosque Subandino. Between April and September 1983 observations were made on the relations between Thalurcnia furcata colombica and flowers in the laguna de Pedro Palo area (Cundinamarca, Colombia). The hummingbird was seen visiting 15 species of plants (beloging to 13 families) situated mainly on the edge of forest, among which the following species showed a high degree of ornithophily: Besleria solanoides (Gesneriaceae), Bomarea racemose (Amaryllidaceae), Cornutia odorata (Verbenaceae), Erythrina edulis (Fabaceae) and Palicourea popayanensis (Rubiaceae). Nectar was available for hummingbirds during the six months of study. Although males and females of the species had similar habitat and food preferences, a relatively small number of agressive encounters between them was recorded. Three mechanisms were recognized which contributed to reduce these encounters: 1. a difference in foraging strategies, males being predominantly territorial and females generalists (behaving as territorial or 'trapliners' according to circumstances) ; 2. differences in the temporal organization of their foraging activity through the day; 3. differences in spatial organization, males and females tending to exploit different parts of the same plant. Thalurania furcata defended its feeding territories against individuals of its own and other species of hummingbirds (Chlorostilbon gibsoni, Coeliqena prunellei and others), flower-piercers (mainly Dlglossa sittoides), and butterflies.

Title A name given to the resource IPR 82-Araucária, cultivar de batata para olericultura sustentável IPR 82-Araucária, potato cultivar for sustainable vegetable production Creator An entity primarily responsible for making the resource Carlos Alberto Scotti, Nilceu Ricetti Xavier de Nazareno Description An account of the resource São apresentadas as principais características agroindustriais e morfológicas de uma nova cultivar de batata lançada pelo IAPAR, em parceria com a Embrapa Hortaliças, Brasília (DF) e a Embrapa Semente Básica, Canoinhas (SC). 'IPR 82-Araucária' foi selecionada de populações clonais introduzidas do CIP, Lima-Peru, por meio da Embrapa Hortaliças e avaliada nas Estações Experimentais do IAPAR desde 1984. A nova cultivar apresentou como fatores positivos alta produtividade comercial e resistência de campo à requeima, permitindo prever reduções em até 50% no uso de fungicidas para o controle da doença. A suscetibilidade à mancha chocolate e sarna comum evidenciaram a necessidade de manejo adequado de densidade e época de plantio, calagem e irrigação para minimizar os riscos de ocorrência dessas doenças. Com essas características, 'IPR 82-Araucária' apresenta potencial para atender às demandas de produtores orgânicos e para produção em áreas de mananciais de água.The main agronomic, industrial, and morphological characteristics of a new Brazilian potato cultivar released by IAPAR, Embrapa Hortaliças, Brasília-DF and Embrapa Sementes Básicas, Canoinhas-SC are presented. 'IPR 82-Araucária' has been selected from clonal populations derived from crosses done in CIP, Lima, Peru, and introduced for field evaluations in 1984. High yield and field resistance to late blight have been the main features of the new cultivar, allowing to predict reductions as much as 50% in fungicides applications. Susceptibility to internal brown necrosis and common scab requires special farmer's attention in respect of planting density, liming, and irrigation management to decrease risks of incidence of these diseases. 'IPR 82-Araucária' is potentially suited for organic farming, and for growing in areas close to water resources.
