Introduction
PhD - Biological Sciences from Universidad Nacional de Colombia. Mi research experience has center on the assessment of ecological processes at different scales: individual (animal movement); community (diversity, occupation, and occurrence patterns); landscape (effects of fire regimes and forest fragmentation). I belong to different groups and networks that seek to highlight the research in Colombia, the role of women, and healthy scientific and academic collaboration.

Fire is a natural agent with a paramount role in ecosystem functioning and biodiversity maintenance. Still, it can also act as a negative force against many ecosystems. Despite some knowledge of the interactions of fire and vegetation, there is no clear understanding of how different components of fire regimes (i.e., severity, history, or frequency...
Article
Full-text available
Both fire and predators have strong influences on the population dynamics and behaviour of animals, and the effects of predators may either be strengthened or weakened by fire. However, knowledge of how fire drives or mediates predator-prey interactions is fragmented and has not been synthesised. Here, we review and synthesise knowledge of how fire...

Construimos de manera participativa una serie de criterios e indicadores, como herramienta que facilita reunir la información, identificar vacíos y deficiencias, monitorear los cambios en las condiciones de los bosques y la dinámica de fuegos, así como comunicar de forma más eficiente el progreso alcanzado en la materia. Esta propuesta sirve de mar...

La dinámica del fuego en la cuenca del río Bita es compleja y de proporciones aún desconocidas, especialmente en las formas en las que se han visto impactados los bosques de galería, morichales, humedales y sabanas. El presente protocolo por un lado busca contribuir a la síntesis del conocimiento actual para que los tomadores de decisiones diseñen...
Article

Fire plays a dominant role in deforestation, particularly in the tropics, but the relative extent of transformations and influence of fire frequency on eventual forest loss remain unclear. Here, we analyze the frequency of fire and its influence on postfire forest trajectories between 2001 and 2018. We account for ~1.1% of Latin American forests bu...

El conocimiento del estado de la vegetación de los bosques de galería es fundamental para el diseño de estrategias de manejo orientadas a la conservación de la diversidad de especies de flora y fauna, así como los servicios ecosistémicos que prestan estos bosques. Por ello se realizó un análisis de la composición y estruc�tura de los bosques de...

El cambio climático y el uso del suelo han alterado los regímenes del fuego, impactando ecosistemas sensibles al fuego como los bosques de galería. Ante este panorama, el objetivo de este trabajo fue conocer la respuesta de la vegetación al fuego utilizando como modelo la palma Astrocaryum jauari (Arecaceae), para lo cual se analizó la estructu...

Natural Reserves of the Civil Society (NRCS) play a fundamental role for the conservation of the mastofauna and its habitats in the Colombian Orinoquia and Guyana. The Omacha Foundation in the Bojonawi Natural Reserve-BNR, is carrying out a characterization and monitoring program for this taxonomic group. To date, 36 species, of non-flying aquatic...

Fire is a global disturbance that has a strong influence on biodiversity. Seasonal fires are common in neotropical savannas of South America, yet few studies have analyzed how the fauna of these habitats and nearby forests respond to fire. We evaluated the effects of fire on the community of non-volant small mammals in the Colombian llanos by compa...
Article
Biodiversity faces many threats and these can interact to produce outcomes that may not be predicted by considering their effects in isolation. Habitat loss and fragmentation (hereafter 'fragmentation') and altered fire regimes are important threats to biodiversity, but their interactions have not been systematically evaluated across the globe. In...
Article
Full-text available
Gallery forests are widespread in most tropical savanna landscapes creating a mosaic of grass dominated systems with tree components and forest patches. Interactions among water, nutrient availability, and wildfires have influenced the structure, patterns, and processes of these landscape systems and have shaped today’s biodiversity in the savanna–...

We report the first confirmed occurrence of the Guianan White-eared Opossum, Didelphis imperfecta Mondolfi & Pérez-Hernéndez, 1984 (Didelphimorphia, Didelphidae), from Colombia. The individual was captured in a tropical lowland rain forest in the easternmost portion of the Colombian Orinoco Llanos region. The species is endemic of the Guiana Shield...

Los ecosistemas tropicales albergan una gran parte de la biodiversidad mundial y a pesar de ello están siendo transformados por el cambio de uso de la tierra a un ritmo sin precedentes. La conversión de la cobertura de la tierra y el mantenimiento de pastos y áreas para cultivos en Latino América están altamente relacionados con el uso del fuego. E...

In the last decades, wildfires have burnt millions of hectares of tropical forests, resulting in strong negative environmental, social, cultural and economic impacts. It is thought that this trend is going to increase due to the interactions among climate change, vegetation conditions and the mismanagement of land use. The acknowledgment of the pol...

Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental fact...

Changes in land use and land cover (LULC) are important drivers of environmental changes in the tropics. Amazônia Legal has showed some declines in deforestation rates, but NW Amazonia has become one of the most recent/new hotspots of forest loss in the Amazon basin. Regional models of change are tools that support the analysis of causes and conseq...

La acción del hombre y la variabilidad climática asociada al calentamiento global está afectando la incidencia de fuegos en las regiones tropicales, aumentando tanto su intensidad como su frecuencia, particularmente en periodos de sequías. En este estudio se realizó un análisis espacio temporal para identificar la ocurrencia de fuegos dentro y fuer...

Uncertainty in thematic maps has been tested mainly in maps with discrete or fuzzy classifications based on spectral data. However, many ecosystem maps in tropical countries consist of discrete polygons containing information on various ecosystem properties such as vegetation cover, soil, climate, geomorphology and biodiversity. The combination of...

Telemetry based on Global Positioning Systems (GPS) makes possible to gather large quantities of information in a very fine scale and work with species that were impossible to study in the past. When working with GPS telemetry, the option of storing data on board could be more desirable than the sole satellite transmitted data, due to the increase...

The Colombian tapir is found in the Sierra Nevada de Santa Marta; it is an endemic subspecies that presents high risk of vulnerability of local extinction, because of habitat loss and hunting. This study assessed the coverage use of the Colombian tapir in the basins of the Ancho and Palomino (Sierra Nevada de Santa Marta) rivers using telemetry and...
Article
The ecological characteristics of forest edges have been intensively studied in the Amazon region, but the occurrence and intensity of fires as large-scale edge effects are less well known, as is the role of different types of management in modifying this relationship. We used remote sensing techniques to examine the relationship between forest fra...
