Mapping Mountain Landforms and Its Dynamics: Study Cases in Tropical Environments
(2022)
High mountain areas are critical for water security and natural hazard dynamics, as well
as glacier and ecosystem conservation in a warming world. We present a brief account of the
methodological steps for geomorphological ...
Taxonomic approach and potential anthropic indices to understanding cross-sectional morphology and landscape modification of a tropical river Basin, India
(2023)
During the Anthropocene, human modifications to fluvial landscapes
have become a common aspect of their progress and development.
The primary objective of this research is to delve into the humaninduced
alterations on ...
Unidades morfotectónicas-volcánicas del sector noroeste del volcán Poás, Costa Rica
(2021)
La dinámica tectónica y volcánica de Costa Rica
responde principalmente a la interacción de las placas Cocos y Caribe. Con base en la relación entre las estructuras
geológicas, rangos altitudinales, parámetros morfométricos

Natural disaster risk inequalities in Central America
(2022)
Central America is affected by geological and hydrometeorological hazards
that, together with its high exposure and vulnerability, comprise risky scenarios for disasters. This region presents a significant number of ...
Climate reverses directionality in the richness–abundance relationship across the World’s main forest biomes
(2020-11-06)
More tree species can increase the carbon storage capacity of forests (here referred to as the
more species hypothesis) through increased tree productivity and tree abundance resulting
from complementarity, but they can ...
Dendrogeomorphology as a tool to depict hydrogeomorphic processes in the tropics
La dendrogeomorfología como una herramienta para representar procesos hidrogeomorfológicos en los trópicos
(2023-01)
Climatic and anthropogenic changes cause the deprivation of distinct
ecosystems in Costa Rica, transforming climatic, ecological, and geomorphic
conditions. The high tropical biodiversity of Costa Rica and the tropics ...
Global patterns of tree density are contingent upon local determinants in the world’s natural forests
(2023)
Previous attempts to quantify tree abundance at global scale have largely neglected the role of local competition in modulating the influence of climate and soils on tree density. Here, we evaluated whether mean tree size ...
Flood Hazard Index Application in Arid Catchments: Case of the TaguenitWadi Watershed, Lakhssas, Morocco
(2022)
During the last decade, climate change has generated extreme rainfall events triggering flash
floods in short periods worldwide. The delimitation of flood zones by detailed mapping generally
makes it possible to avoid ...
Tropical and subtropical dendrochronology: Approaches, applications, and prospects
(2022-09)
Tropical and subtropical forests cover only 7 % of the Earth’s land surface. Yet, they host nearly half of global tree density with a high species number (~40,000 species), store up to 25 % of global terrestrial carbon and ...
