La conservación de la biodiversidad puede ser más ética y eficaz enfocando simultáneamente la erosión biológica y cultural. Esta idea se encuentra en los postulados funcionales y éticos iniciales de la biología de la conservación. Sin embargo la investigación para la conservación ha enfatizado los inventarios, la cuantificación y la georreferenciación de la diversidad biológica con miras a su utilización. Se le asigna poca relevancia al valor intrínseco de la biodiversidad ante lo cual se hacen llamados a explorar formas apropiadas de “vivir con” la biodiversidad.Esta reflexión responde a ese llamado. Introduce el enfoque biocultural como una perspectiva más comprehensiva para reconocer e investigar las complejas interrelaciones entre procesos ecológicos y dinámicas culturales. Para la investigación se resalta de este enfoque la necesidad de reconocer los derechos de los pueblos indígenas y comunidades locales, al igual que las cosmovisiones que le dan sentido a las prácticas y relaciones que las comunidades establecen con el ambiente. Se explora la base de datos Scienti del período 1991- 2010 en cuanto al registro de investigaciones sobre biodiversidad que involucran conocimiento tradicional y comunidades. Dado el limitado reconocimiento a las contribuciones de las comunidades, se reseñan las principales barreras que encuentra la adopción del enfoque biocultural en investigación. Se proponen premisas éticas orientadas a transformar actitudes y prácticas en investigación que desconocen derechos ancestrales sobre el territorio y el conocimiento, obstaculizan el reconocimiento del valor intrínseco de la biodiversidad, y como resultado impiden garantizar su conservación en un territorio biodiverso, pluriétnico y multicultural. AbstractThe conservation of biodiversity may be deemed ethical and more effective by focusing simultaneously on biological and cultural erosion. This idea was in the functional and ethical principles of the initial understanding in conservation biology. However, biological conservation research has emphasized inventories, quantification and georeferencing biodiversity with utilitarian purposes. Such research gives little importance to the intrinsic value of biodiversity provoking calls to explore appropriate ways of “living with” biodiversity. This paper responds to that call. The biocultural approach offers a more comprehensive view to recognize and investigate the complex interrelationships between ecological processes and cultural dynamics. For research, this approach highlights the need to recognize the rights of indigenous peoples and local communities, as well as the community worldviews that infuse meaning to community practices and relations with the environment. This paper explores biodiversity research data involving traditional knowledge and communities during the period 1991- 2010 in the GroupLac Database. Given the limited recognition to the contributions of communities, this paper outlines the main barriers that the adoption of the biocultural approach faces. The paper proposes ethical guidelines to transform research attitudes and practices that ignore ancestral rights over the territory and traditional knowledge, hinder the recognition of the intrinsic value of biodiversity, and as a result, prevent conservation in a biodiverse, multiethnic and multicultural territory

The study aimed to determine the toxicity of lambda-cyhalothrin, alpha-cypermethrin, and deltamethrin in L. longipalpis, through concentration-mortality bioassays. The test here was performed following WHO guidelines, but instead of using exposure WHO recipients and impregnated papers, 250 ml Wheaton glass bottles treated with 1 ml of insecticide solution were used. Batches of ten females of L. longipalpis were exposed to five concentrations of each pyrethroid that caused between 5 and 100 % mortality in this species. After 1 h of exposure, the females were transferred to observation recipients, and mortality was recorded 24 h later. The lethal concentrations (μg/ml) that killed 50 and 95 % (LC50 and LC95) of the exposed L. longipalpis females were 0.05 and 0.86 for lambda-cyhalothrin, 0.24 and 3.62 for alpha-cypermethrin and 0.53 and 4.72 for deltamethrin. Based on the LC50 obtained, lambda-cyhalothrin is the most toxic pyrethroid for L. longipalpis, followed by alpha-cypermethrin and deltamethrin. It is expected that these data may be useful in studies on the effects of sub-lethal concentrations of the three pyrethroids on the behavior of L. longipalpis and studies on the vector susceptibility to these pyrethroids.

The Procyonidae family is a member of the order Carnivora. It distributes along the American continent, from South Canada to North Argentina; Colombia has in its territory seven species of this family. This paper presents a taxonomic key to differentiate the species of procyonids in Colombia, and a preliminary map of their distribution. The key and the distribution map, were based on the analysis of 67 individuals of the Instituto de Ciencias Naturales collection in Bogotá, 78 of the Instituto Alexander von Humboltd collection in Villa de Leyva and a literature review. The results show a taxonomic key of cranial and external characters for the species identification of the Procionidae family in Colombia and a preliminary distribution of their species.

Tracks and signs are very useful for detecting medium and big mammals, which usually are out of sight. These are helpful tools on field investigation, provide detailed information on the identity and activities of an animal in a place, and can provide us indications of their habitat use (Aranda, 1981a; Navarro & Muñoz, 2000; Villalba & Yanosky, 2000). In this paper we characterize the habitat use of medium and big land mammals in Los Mangos forest. We use an observation and track tramp transect, and a modification of the Habitat Suitability Index (HSI) for evaluating habitat suitability. We detect six burrows, four footprints and five Seje palm (Oenocarpus batagua) feeding places, in addition to ten tracks compiled along the other days of field investigation. We recognized ten species of mammals which belong to five orders, using tracks and bitted fruits. The HSI calculated was 7.30 on inner forest, indicating that the habitat is appropriate for animals which use burrows. Resources like food (insects, fruits and preys), refuge, water and resting places converges generating favorable environment for immigration and residence of insectivore, frugivore and carnivore mammals. The fertile plane forest is an important habitat of this area because present there. It offers quality resources to the animal species in there.
