Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

open access: yesInternational Journal of Climatology, EarlyView.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

open access: yesLand Degradation &Development, EarlyView.
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 ...

Analysis of the Matrix Metalloproteinases Family Profile in Gastric Cancer Suggests Key Matrix Metalloproteinases for Tumor Development and Their Clinical Impact

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Gastric cancer (GC) is the fifth most common type worldwide, representing a public health problem. Among the genes related to this tumorigenesis, the family of matrix metalloproteinases (MMPs), essential regulators of the extracellular matrix (ECM), stand out for their involvement in the development and progression of GC.

Clarifying nomenclatural uncertainties in Jupunba (Caesalpinioideae, Leguminosae)

open access: yesNordic Journal of Botany, EarlyView.
Molecular phylogenetic studies have prompted substantial revisions in the systematics of the former genus Abarema, resulting in the reinstatement of the genera Punjuba and Jupunba, and a re‐circumscription of Abarema. Despite these advances, some taxa still require nomenclatural adjustments to reflect monophyletic lineages.
