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.

La creciente transformación y degradación de los ecosistemas terrestres es cada vez más evidente en grandes extensiones de la superficie terrestre. Particularmente la pérdida de bosques ha llevado a que los países asuman compromisos internacionales de restauración forestal a escala de paisaje. En este sentido, la ecología del paisaje ha tomado rele...
The native savannas of eastern Colombia cover about six percent of the Neotropical savannas. Within these 17 million hectares, the current composition of nonflying mammals evidenced colonization from Andean, Guyanese, and Amazonian speciation centers and endemism processes. Scientific knowledge of the mammal species in native savanna ecosystems in...
In Colombia, three of the four recognized tapir species are recorded, making the country the largest diversity hotspot for the Tapirus genus in the world. The mountain tapir (Tapirus pinchaque) inhabits the ecosystems of the Central and Eastern Andes, lowland tapir (T. terrestris) in the Caribbean, Orinoquia and Amazonia, and the Central American t...
The tapirs are large terrestrial mammals, anatomically and physiologically adapted to almost all habitats and ecosystems. Despite its importance in seed dispersal, preservation and reconstruction of habitats, information on infectious agents that affect these animals is still incipient. The objective of this study was to detect natural Trypanosoma...

The suitable area for T. terrestris with the most representative savanna landscapes being: (i) savannas (118,125 2.2%) of the suitable area was reported within Civil Society Nature Reserves. Our results highlight the ec...
The native savanna ecosystem of the Orinoquia region is the habitat of 50% of the wild ungulate species reported for Colom-bia. Over the last 20 years, this high species diversity has been strongly threatened by the human transformation of the natural land cover causing connectivity loss of the habitats. The Orinoquia region lacks a biological conn...
The high plains native savanna landscape (HPNSL) northeast of the Orinoco River is the habitat of 50% of the wild ungulate species (WUS) reported for Colombia. Over the last 20 years, this high species diversity has been strongly threatened by the accelerated human transformation of the natural land cover causing connectivity loss of the habitats....
Fires are recurrent in moist tropical savannas, but in recent decades, Neotropical forests have become more affected due to the increased frequency of fires and the extent of burned areas. Currently, there is still limited knowledge on whether and how these disturbance events generate changes in taxonomic and functional diversity that can ultimatel...
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...
Land use policies and planning in Latin America have been partially successful in halting deforestation yet have not stopped forest degradation. Here, we study the different stakeholders' perspectives of the drivers of forest degradation. We use Colombia as a case study for understanding synergies and trade-offs of the sustainable development goals...
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...

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...
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...
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...

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...
