Cooperative and Non‐Cooperative Solutions in a Dynamic Model of Forest Management

open access: yesNatural Resource Modeling, Volume 39, Issue 3, August 2026.
ABSTRACT This study develops a deterministic finite‐horizon bioeconomic control model linking forest biomass, biodiversity, cumulative harvesting pressure, and disturbance‐motivated expected biodiversity losses. Biodiversity is modeled as a productive state variable that feeds back into biomass growth, while cumulative harvesting pressure records the ...

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...

RELAÇÃO DE BIO-ANCESTRALIDADE NA AMAZÔNIA, A SOBERANIA E OS TRATADOS INTERNACIONAIS: CDB E CONVENÇÃO 169 DA OIT, HERMENÊUTICA EMANCIPATÓRIA E DESENVOLVIMENTO

Revista Culturas Jurídicas, 2022
Em intrínseca relação entre o biológico, a ancestralidade e as relações de soberania, a Amazônia é uma das regiões de conflitos pluriétnicos na América Latina. Nesse sentido, indaga-se: o elemento soberania, presente na Convenção da Diversidade Biológica - CDB e na Convenção 169 da Organização Internacional do Trabalho – OIT, sobre os Povos Indígenas e

Geoambientes e solos de Campos Rupestres Ferruginosos da Amazônia: a Serra de São Félix

Os Complexos Rupestres (CR) brasileiros são ecossistemas diversos que podem variar conforme a profundidade do solo, drenagem, estabilidade e evolução da paisagem. Estão associados a várias litologias, especialmente quartzitos e rochas ferríferas, e são marcados por elevada diversidade e endemismo, mas enfrentam riscos de degradação pela ...
