Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)
Land Degradation &Development, Volume 37, Issue 9, Page 4368-4382, 30 May 2026.ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Solar system tests of scalar field models with an exponential potential
, 2008 We consider a scenario where a scalar field has dynamics ruled by an exponential potential, such as those arising from some quintessence type models, and aim at obtaining phenomenological manifestations of this entity within our Solar System.

Revista de Biología Tropical, 2010 The phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes ...

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

Traversable Wormholes and Time Machines in non-minimally coupled curvature-matter $f(R)$ theories
, 2012 We obtain traversable wormhole and time machine solutions of the field equations of an alternative of gravity with non-minimally curvature-matter coupling.

American Ethnologist, Volume 53, Issue 2, Page 171-182, May 2026.Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

Solar System constraints to nonminimally coupled gravity
, 2013 We extend the analysis of Chiba, Smith and Erickcek \cite{CSE} of Solar System constraints on $f(R)$ gravity to a class of nonminimally coupled (NMC) theories of gravity.
