Introduction
Landscape ecology is my work passion, together with fire ecology, spatial analysis and modelling for biodiversity conservation. I will keep contributing to the understanding of ecological processes across multiple organizational levels and scales. My research interests focus mostly on tropical landscapes that are hotspots of deforestation and fragmentation. # fire ecology, deforestation, LULC, fragmentation, ecosystem assessments, ES, conservation biology, biodiversity, spatial ecology, policy

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–...

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...

Global scientific partnerships should generate and share knowledge equitably, but too often exploit research partners in lower-income countries, while disproportionately benefitting those in higher-income countries. Here, I outline my suggestions for more-equitable partnerships.
Article
Full-text available
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...
Article
Full-text available
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
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...
Preprint
The global target to protect 30% of Earth’s land and ocean by 2030 has prompted governments to report their progress in biodiversity conservation. Announcements of countries reaching 30 % of conservation area are widely commended by the international community, despite signs of increasing pressures within protected areas, poor representativity of k...
Article
Full-text available
Reducing deforestation underpins global biodiversity conservation efforts. However, this focus on retaining forest cover overlooks the multitude of anthropogenic pressures that can degrade forest quality and imperil biodiversity. We use remotely sensed indices of tropical rainforest structural condition and associated human pressures to quantify th...

Las Comunicaciones Nacionales sobre Cambio Climático (CNCC) son un mecanismo para que los países informen sus avances en mitigación y adaptación, y constituyen uno de los elementos de base para la política sobre cambio climático a escala nacional. Colombia ha emitido tres CNCC. La tercera plantea un escenario que considera las proyecciones de diver...

Article
Full-text available
Payment for ecosystem services (PES) schemes are an increasingly important approach that often try to achieve triple bottom line solutions-achieving biodiversity conservation and social equity-, while minimizing costs. However, when planning for multiple objectives with a limited budget, spatial mismatches and trade-offs between objectives are like...

Rapid climate changes and the increasing presence of humans define the Holocene Epoch (11.6 calibrated kiloyears before present – hereafter kyr BP), when biological systems have faced the most recent and abrupt environmental changes. Understanding how biodiversity responds to extrinsic factors requires determining the effects of varying climatic co...

Full-text available
‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous. We sought to resolve ambiguity surrounding the meaning of ‘megafire’ by conducting a structured review of the use and definition of the term in several languages in the peer‐review...

Unsustainable fisheries practices carried out in large parts of the Amazon, Tocantins, and Orinoco basins have contributed to the decline in the populations of the Amazon River dolphins (Inia spp.), considered Endangered by the International Union for Conservation of Nature (IUCN). Amazon River dolphin byproducts are often obtained through unregula...

Amazon aquatic ecosystems are being destroyed and the threats to their integrity are projected to grow in number and intensity. In this chaper we review a number of these threats. Hydroelectric dams (n=307 existing or under construction) have changed almost every aspect of Amazon aquatic ecosystems, and many more dams are planned (n=239), posing th...

Deforestation, the complete removal of an area’s forest cover; and forest degradation, the significant loss of forest structure, functions, and processes; are the result of the interaction between various direct drivers, often operating in tandem. By 2018, the Amazon biome had lost approximately 870,000 km2 of its original forest cover, mainly due...

Population growth with weak economic development can promote tropical deforestation, but government infrastructure investment can also open new frontiers and thus increase deforestation. In the Andean region of South America, population growth has been a leading explanation for both deforestation and coca cultivation, but coca generates armed confl...

Mineral licks are faunal attractors, whose distribution determines the structure and composition of Amazonian landscapes and the way they are used by wildlife and traditional communities. Research on the distribution of mineral licks is scarce, limiting the possibility of using them in conservation beyond local scales. Using the species distributio...

Studying the variables that describe the spatial ecology of threatened species allows us to identify and prioritize areas that are critical for species conservation. To estimate the home range and core area of the Endangered (EN) Amazon river dolphin Inia geoffrensis , 23 individuals (6♀, 17♂) were tagged during the rising water period...

There are multiple pressures on Amazon forests due to, anthropic activities such as extensive cattle ranching, logging, and legal and illegal crops. These pressures generate highly fragmented landscapes that leads to an increase in forest edges. Thus, forest vegetation exposed to the surrounding open environment generates a series of direct effects...

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.
