Introduction
I am a forest ecology scientist who explores the functional responses of tropical forests to environmental harshness and its effects on ecosystem functioning. I have a particular interest and fascination for tropical dry forests. I am a researcher at the Biodiversity Science Program, Instituto de Investigación de Recursos Biológicos Alexander von Humboldt, Bogotá, Colombia, South America, where I currently lead the Colombian Tropical Dry Forest Network (https://redbst-col.com/es/)

Analyzing the spatial association pattern among species can help to better understanding the mechanisms that drive forest dynamics and assembly. We applied techniques of spatial point pattern analysis to data from a fully mapped plot of tropical dry forest (TDF) in Colombia to assess the spatial association network among the eight most abundant spe...
Tropical forests are some of the most biodiverse ecosystems in the world, yet their functioning is threatened by anthropogenic disturbances and climate change. Global actions to conserve tropical forests could be enhanced by having local knowledge on the forestsʼ functional diversity and functional redundancy as proxies for their capacity to respon...
Aims
Tropical dry forests are one of the most threatened ecosystems on Earth, and understanding the effects of climate on its species distributions is critical to mitigate global change impacts. Here, we assessed the impact of precipitation and dispersal limitation by natural and anthropogenic causes on phylogenetic and taxonomic beta diversity of...
Leaf habit has been hypothesized to define a linkage between the slow‐fast plant economic spectrum and the drought resistance‐avoidance trade‐off in tropical forests (‘slow‐safe versus fast‐risky’). However, variation in hydraulic traits as a function of leaf habit has rarely been explored for a large number of species. We sampled leaf and branch f...
Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...
Tree-based forest landscape restoration interventions require knowledge on the suitability and origin of seed sources and planting material. A common recommendation is to select locally sourced material based on the assumption that it is well adapted to local environmental conditions and to avoid introduction of maladapted genes. However, faced wit...
Tropical dry forests (TDF) are widely distributed in the Neotropics, where they have been shaped by human settlements for centuries. In Colombia, located at the northern portion of South America, only 8% of TDF remain as forest fragments in three regions: the Caribbean in the North, the Inter Andean Valleys at the center of the country, and the Ori...
Extreme drought events have negative effects on forest diversity and functioning. At the species level, however, these effects are still unclear, as species vary in their response to drought through specific functional trait combinations. We used long-term demographic records of 21,821 trees and extensive databases of traits to understand the respo...
Although one-quarter of plant and vertebrate species are threatened with extinction, little is known about the potential effect of extinctions on the global diversity of ecological strategies. Using trait and phylogenetic information for more than 75,000 species of vascular plants, mammals, birds, reptiles, amphibians, and freshwater fish, we chara...
En 2014 nació la “Iniciativa Biodiversidad y Desarrollo” de la Asociación Nacional de Empresarios de Colombia – ANDI –, bajo el convencimiento que la actividad empresarial, la protección y restauración de los ecosistemas, son compatibles. La Iniciativa se ha desarrollado en asocio con el Instituto de Investigación de Recursos Biológicos Alexander v...
Conservationists recognize the value of protected area (PA) systems, with adequate coverage, ecological representation, connection, and management to deliver conservation benefits. Yet, governments primarily focus on coverage, disregarding quantification of the other criteria. While recent studies have assessed global representation and connectivit...
Understanding of tropical forests has been revolutionised by monitoring in permanent plots. Data from global plot networks have transformed our knowledge of forests’ diversity, function, contribution to global biogeochemical cycles, and sensitivity to climate change. Monitoring has thus far been concentrated in rain forests. Despite increasing appr...

Tropical dry forests (TDF) are known to be resource‐limited due to a marked seasonality in precipitation. However, TDF are also shaped by factors such as solar radiation, wind speed, soil fertility, and land‐cover transformation. Together, these factors may determine different gradients of environmental harshness that are likely to drive changes in...

Tropical dry forests (TDF) have been heavily fragmented in Colombia, where 8% of the original TDF remain, and only 5% of what is left is under protection. Moreover, more than 90% of the remaining dry forests remain in private areas, making it urgent to find incentives for landowners to preserve the little TDF left. Our objective was to quantify the...
Chapter 2 represents the first study to compile plant species data from dry tropical forests (DTF) from the six different regions where this ecosystem occurs in Colombia. However, it is clear that even this basic information is poor in some regions of dry forests in the country. Regardless of these limitations, analyses on the floristic composition...
