Title A name given to the resource Aspectos ecológicos da leishmaniose tegumentar americana: 3. Observações naturais sobre o ritmo diário de Psychodopygus intermedius em ambiente florestal e extraflorestal Ecological aspects of American cutaneous leishmaniasis: 3. Natural observations on the daily rhythm of the activity of Psychodopygus intermedius in forested and neighbouring environments Creator An entity primarily responsible for making the resource Almério de Castro Gomes, Eunice Aparecida Bianchi Galati, Jair Lício Ferreira Santos, Ernesto Xavier Rabello Description An account of the resource Pela primeira vez se determina a atividade diária de Psychodopygus intermedius em ambiente florestal residual e extraflorestal, em Pariquera-Açú, Região do Vale do Ribeira, Estado de São Paulo, Brasil. A análise final revelou ter esse flebotomíneo atividade noturna nos dois ambientes. Contudo, houve divergência quanto ao pico de atividade máxima que oscilou entre 20 e 02 horas. Persistiu também a sua predominância no ambiente extraflorestal. Por outro lado, uma acentuada preferência pelo homem parece ter influenciado sua dispersão, pois demonstrou ser ubiquitária. A importância do evento reside na possibilidade de haver uma estreita associação alimentar Ps. intermedius-Homem. Subsequente, a infecção leishmaniótica poderá ocorrer ao nível do domicílio.The daily activity of Psychodopygus intermedius was measured for the first time, within and outside of a residual forest in the Ribeira Valley, S. Paulo State, Brazil. The results showed nocturnal activity in both environments, with different times of maximum activity occuring between 8 p.m. and 2 a.m. However, the most intense activity continued to take place outside the forest. A strong preference for humans seems to have contributed to Ps. intermedius' ubiquitous distribution. The importance of this fact lies in the possibility of there existing a close feeding association Ps. intermedius - Man. Hence cutaneous leishmaniasis infection may take place in the household environment.

Title A name given to the resource La ecología humana en el contexto de la ciudad de Bogotá. Breve estudio de caso de aplicación en la Transferencia y Apropiación social de Conocimiento: los Modelos Basados en Agentes Creator An entity primarily responsible for making the resource Iván Darío Medina Rojas Description An account of the resource El paradigma dominante observado hoy en día se encuentra en proceso de colisión con el entorno natural, dicho paradigma se encuentra inmerso en un enfoque obnubilado por su mecanicismo, su individualismo, su reduccionismo y con una mirada muy cuantitativa y antropocéntrica de la naturaleza. Ya Thomas Robert Malthus nos había dado un campanazo hace más de dos siglos en su obra “Ensayo sobre el principio de la población” cuando dejó la preocupaciónsobre un crecimiento geométrico de la población mientras uno aritmético de los recursos, si bien es cierto que una perspectiva de paradigma cambiante es relativamente mucho más reciente, ya que toma gran fuerza con la aparición del concepto de desarrollo sostenible, con una visión totalmente distinta al convencional ya que permite un enfoque biocéntrico, interconectado, holístico y de cooperación, deja de lado ese mecanicismo y el valor cuantitativo por el valor cualitativo. No obstante, tiempo atrás a la aparición del concepto, la sociedad industrializada se enfrentaba a un fenómeno que ha sido tendencia derivada de la revolución industrial, los procesos migratorios a las ciudades y todos los cambios de orden social, económico, político, ambiental y cultural que trae consigo; en la Escuela de Chicago de Sociología aparece una rama denominada “Ecología Humana” que, en pocas palabras, propende por un diseño metodológico cualitativo, el estudio del hombre en su hábitat natural que se escala a relaciones urbano-sociales al establecer el paralelo entre sistemas sociales y naturales, una forma de comprender los procesos llevados a cabo en una ciudad.

Title A name given to the resource Influencia de la luz azul sobre la productividad del cultivo sólido de Ganoderma lucidum Creator An entity primarily responsible for making the resource Sandra Montoya, Diana M. López, Belarmino Segura Description An account of the resource Ganoderma lucidum es un hongo macromiceto reconocido por sus propiedades medicinales y su contenido de compuestos bioactivos que incluyen polisacáridos, triterpenoides, proteínas inmunomoduladoras, entre otros, lo que ha generado un incremento notable en su producción. La mayoría de especies de hongos responden y se adaptan a diversas señales ambientales incluida la luz, que favorece su productividad, tanto en calidad como en cantidad al estar estrechamente relacionada con la formación de cuerpos fructíferos. Por tal razón, el objetivo de este estudio fue evaluar la eficiencia biológica (EB) y la tasa de producción (TP) como parámetros de productividad del cultivo sólido de Ganoderma lucidum bajo irradiación de los sustratos con luz emitida por diodos azules (LED) con dos periodos de foto-estímulo de 12 y 24 h durante todas las fases de cultivo para inducir el crecimiento micelial y la formación de los cuerpos fructíferos. Se aplicaron parámetros convencionales para el crecimiento y desarrollo del hongo en las etapas de producción. Para la formulación de los sustratos, se emplearon residuos agroindustriales y materiales lignocelulósicos. El diámetro de los cuerpos fructíferos sometidos a tratamientos con luz azul fue mayor que los exhibidos a luz blanca fluorescente (Testigo). Los resultados muestran que el cultivo de Ganoderma lucidum con exposición a la luz azul es útil para la inducción de cuerpos fructíferos de alta calidad, logrando una disminución del periodo de fermentación en 16 días para el foto-estímulo de 24 h con EB de 28,04% y TP de 0,64.

Title A name given to the resource Producción de biomasa, diversidad y ecología de especies en un gradiente de productividad en el matorral espinoso tamaulipeco del Nordeste de México Creator An entity primarily responsible for making the resource R. Espinoza-Bretado, J. Návar Description An account of the resource La producción de biomasa y su asociación con la diversidad es un indicador de la condición de los ecosistemas; provee las bases parael manejo sustentable de los recursos naturales. Se hacen observaciones de producción y diversidad en 15 cuadrantes del matorralespinoso tamaulipeco, establecidos en un gradiente de productividad en cinco sitios con tres repeticiones. Se determinó diversidadalfa y beta con varios índices. Se definió la relación producción-diversidad y se ajustó un análisis de correspondencia canónica sintendencia. Se observa que los sitios con mayor producción presentan la menor diversidad alfa, mientras que sitios con menorproductividad poseen mayores índices de diversidad. El modelo barra rota se ajustó a la mayoría de los cuadrantes, indicando laestabilidad de diversidad – abundancia en las etapas secundarias de la sucesión vegetal. La diversidad beta fue baja y se explica porla baja plasticidad de las especies muestreadas. El análisis multivariado mostró gradientes notorios en la distribución de especies ysitios, de acuerdo a sus niveles de productividad y geomorfología. La presencia de mayor número de especies en sitios pobres seexplica parcialmente por sus bajos y diferentes requerimientos nutricionales, la diferenciación en la explotación del recurso espaciotiempoy a los diferentes patrones fisiológicos.
