Prior to this regional Red List report, 199 endemic tree species have been evaluated in national Red Listing initiatives. Including these national evaluations with the findings in this report, a total of 235 tree species have been identified as threatened in the tropical Andes.

The opening of different investigative directions based on diverse lines of research has created a need to consolidate and systematize the different approaches that have been adopted. Much current research is oriented towards examining how local practices influence biodiversity and the conservation of natural resources. The last decade has also seen an increase in the number of published works examining and standardizing research methodologies. The chapters of this book have thus sought to capture some of these new trends in ethnobotany, and we hope they can contribute to exchanging experiences among ethnobotanical investigators. This book comprises eight chapters with distinct focuses, including case studies based on ecological, biological, and social approaches, discussions of methodologies used in data collection, as well as state-of-the-art investigations into new/old areas of ethnobotanical inquiry...

To test if leaf driptips facilitate leaf drying after rainfall in a tropical rain forest of Costa Rica, we (1) experimentally measured the capacity to retain water on leaf surfaces of 30 plant species before and after driptip removal, and (2) analyzed the development of driptips along forest strata. We expected leaf driptips to be less developed in the upper strata due to the environmental conditions of the canopy (i.e., high solar radiation, strong winds and low relative humidity), which favor the natural drying of leaves. The presence of driptips increased 100% the water run off capacity of leaves in all the analyzed species. Also, the development of leaf driptips was smaller in canopy species than in understory species. Additionally, they became less developed in c...

Es una disciplina que integra el conocimiento biologico-ecologico de las especies con aspectos socioculturales de los grupos humanos y cuyo interes estriba en el estudio del como el ser humano utiliza a la naturaleza, la percibe, nombra, interpreta y organiza su conocimiento.

Evaluación del estado de conservación de los bosques montanos en los Andes tropicales. Ecosistemas 21(1-2):148-166. Los Andes tropicales constituyen una región única con una alta diversidad de hábitats, producto de complejos gradientes espaciales y ambientales. Los bosques montanos de esta región son considerados como una prioridad global de conservación, debido principalmente a su elevada riqueza biológica y de endemismos. Sin embargo su biodiversidad es de las menos conocidas de toda la región tropical, aunque se reconoce la amplia gama de servicios ambientales que prestan, incluyendo la regulación del clima regional y la captura y almacenamiento de carbono. Este artículo ofrece una perspectiva general del estado de conservación de los bosques montanos tropicales andinos y de los retos que esta implica. Asimismo, proporciona información sobre sus amenazas, identificando aquéllas que con mayor probabilidad sean responsables de aumentar el riesgo de extinción de especies. Se resalta la necesidad de disponer de más información sobre el estado de conservación de las especies para identificar las futuras prioridades de conservación en la región. La reciente iniciativa de la "Lista Roja y planeación para la conservación de especies de árboles montanos de los Andes Tropicales", formada por delegados de varios países de la región, constituirá una sólida base para el desarrollo y enfoque de políticas y respuestas de manejo dirigidas a la reducción de la deforestación y pérdida de especies en estos bosques, incluyendo acciones para promover la creación de áreas protegidas, restauración forestal y manejo forestal sostenible.

In this context, we investigated the variation of local ecological knowledge through the richness of cited species, redundancy on an individual level and utilitarian redundancy (fuel, construction and technology) by local populations inserted in a dry forest with different environmental characteristics in northeastern Brazil. Methods: We conducted semi-structured interviews with 120 local experts and described metrics which indicate the intensity of chronic human disturbance, defined as ongoing activities to remove natural resources, as well as the average annual rainfall in forests close to populations. Results: We verified that there are differences between the number of species mentioned and the utilitarian redundancy between the studied areas. The richness of known species is suggested to influence redundancy on an individual level. Furthermore, we observed that information sharing about the plants among local experts is different, as some species were shared more than others. Conclusions: Our results suggest that people living in areas of greater chronic anthropic impact and less rainfall may be subject to a lower resilience of local knowledge.

La metodología empleada se basó en el método Descriptivo - Analítico, programando 2 viajes a la zona de acuerdo a la estacionalidad climática. Como resultado se han colectado 150 especies agrupadas las angiospermas en 51 familias : 46 dicotiledóneas 5 monocotiledóneas, 1 gimnosperma, 4 pteridofitas y 1 líquen.

Por otro lado existe una prioridad alrededor de las plantas silvestres de la Jalca ( 3,500 - 4,000 msnm.). La etnoclasificación al interior de la especie se basa en el color, el tamaño, la apariencia sensible y el sexo en la mayoría de los casos. Finalmente los nombres dados a las especies y variedades tienden a ser una descripción de su morfología y de su utilidad.
