En esta investigación nos hemos centrado en analizar el nivel de sofisticación y tipo de modelo de energía que construyen futuros docentes de física (FD) chilenos a través de una secuencia de enseñanza y aprendizaje centrada en la modelización. Para ello, analizamos las producciones escritas de los FD en un momento inicial y final de la formación p...
El objetivo de esta investigación fue contribuir a la conservación del Sistema Arrecifal Mesoamericano, por medio de la generación línea base de los arrecifes coralinos de la Bahía de Trujillo y pastos marinos del Refugio de Vida Silvestre Laguna de Guaimoreto. Este estudio permitió identificar dentro de la Bahía de Trujillo 20 sitios arrecifales,...

The Andean Condor (Vultur gryphus) is a globally threatened species. Its highly mobile capability presents important challenges for conservation planning, especially in extremely geographically complex regions such as Colombia, where little is known about its ecology. Over the past three decades, financial and technical conservation efforts have primarily focussed on reintroduction and local management strategies. However, these initiatives did not properly prioritize the various conservation measures undertaken. We utilized roosting locations across Colombia to identify suitable roosting distribution with high risk because of the anthropogenic impact on a Systematic Planning Tool for decision-making based on robust spatial habitat modelling to define where and how should focus the Andean condor conservation actions in the country. Specifically, we aimed to develop a conservation planning tool to facilitate spatially explicit decision-making. Our results showed that Colombia has at least 19,571.33 km2 of suitable roosting habitat for this species, but over 30% of this area is currently considered to be under conservation risk due to severe anthropogenic impacts. Considering this, we suggested different actions for each proposed area according to potential threats generated by human communities.
The New World Vultures (Cathartidae) include seven species of obligate scavengers that, despite their ecological relevance, present critical information gaps around their evolutionary history and conservation. Insights into their phylogenetic relationships in recent years has enabled the addressing of such information gaps through approaches based on phylogeny. We reconstructed the ancestral area in America of the current species using two regionalization schemes and methods:
Biogeography with Bayesian Evolutionary Analysis (BioGeoBears) and Bayesian Binary Model–Monte Carlo Markov Chains (BBM–MCMC). Then, we identified the priority species and areas for conservation by means of the Evolutionary Distinctiveness index (ED), as a proxy of the uniqueness of species according to phylogeny, and the Global Endangerment index (GE), mapping phylogenetic
diversity. We found that the ancestral area of NewWorld Vultures in America corresponds to South America, with dispersal processes that led to a recolonization of North America by Coragyps atratus, Gymnogyps californianus and Cathartes aura. We identified the Black Vulture, G. californianus and Vultur gryphus as priority species based on ED and “Evolutionary Distinct Globally Endangered” (EDGE)
indexes, and the lowlands of Amazon River basin and the Orinoco basin and some tributaries areas of the Guiana Shield were identified as the priority areas when mapping the phylogenetic diversity. This study highlights the importance of filling knowledge gaps of species of conservation concern through the integration of evolutionary and ecological information and tools and, thus, developing adequate
strategies to enhance the preservation of these species in the face of the current loss of biodiversity.
