En los últimos años, se ha avanzado considerablemente en el conocimiento de la distribución de las especies de aves en Colombia; sin embargo, una muy buena parte de la información sobre la avifauna colombiana se encuentra dispersa en libros, artículos científicos, informes y literatura gris, observaciones personales no publicadas, así como en colecciones públicas y privadas. Estos registros, junto con las capas de información climática, fueron la base con la cual se desarrollaron los modelos de distribución de las especies en los cuales se apoya esta obra.
First Published in 2010. Routledge is an imprint of Taylor & Francis, an informa company.
Ecologists and natural resource managers are charged with making complex management decisions in the face of a rapidly changing environment resulting from climate change, energy development, urban sprawl, invasive species and globalization. Advances in Geographic Information System (GIS) technology, digitization, online data availability, historic legacy datasets, remote sensors and the ability to collect data on animal movements via satellite and GPS have given rise to large, highly complex datasets. These datasets could be utilized for making critical management decisions, but are often “messy” and difficult to interpret. Basic artificial intelligence algorithms (i.e., machine learning...
ntil now there has been no state-of-the-art collection of themost important writings in automatic text summarization. This bookpresents the key developments in the field in an integrated frameworkand suggests future research areas. With the rapid growth of the World Wide Web and electronic information services, information is becoming available on-line at an incredible rate. One result is the oft-decried information overload. No one has time to read everything, yet we often have to make critical decisions based on what we are able to assimilate. The technology of automatic text summarization is becoming indispensable for dealing with this problem. Text summarization is the process of distill...
Developed & published in association with the International Biogeography Society, this book concentrates on advances in historical biogeography, island biogeography & marine biogeography during the past quarter of a century.
This book highlights key results and lessons learnt from two field sites, La Suerte in Costa Rica and Ometepe Nicaragua. It provides long term data on species abundance and distribution. Primates receive specific attention in this book, as they are flagship species and good indicators for the “health” of an ecosystem, but as well a money maker. Many primate species are sensitive to habitat alteration, and are often hunted out first. But they play an important role as seed dispersal agents for the regeneration of the forest. The book then compares results from the two field sites with regional trends, and explores potential solutions such as REDD+. This book strongly calls for new approaches in conservation, it makes the case for looking beyond the pure species biology and classic conservation angle and to take into account the economic and political realities.
Sustainability is a fairly old concept, born in the 18th century in the field of forestry, within a mono-functionality perspective. The concept has considerably evolved in the last few years towards a multi-functionality context, with applications reported in practically all areas of economic interest. On the other hand, modern sustainability is a complex problem, for two reasons: a) The multiplicity of functions of a very different nature involved in the process and b) The manner in which different segments of the society or stakeholders perceive the relative importance of these functions. For the above reasons, a realistic approach for dealing with the sustainability issue requires taking ...
Complex and ever changing in its forms and functions, the element mercury follows a convoluted course through the environment and up the food chain. The process is complicated further by the fact that the difference between tolerable natural background levels and harmful effects in the environment is exceptionally small and still not completely und
