International Legitimation of Authoritarianism: Venezuela's United Nations General Assembly Discourse and Domestic Power Consolidation (1999–2023)

Bulletin of Latin American Research, Volume 45, Issue 3, July 2026.
ABSTRACT This article examines how the Venezuelan government defended the gradual transformation of the country's political system from democracy to authoritarianism in an international forum. Building on the concept of international legitimation strategies, we qualitatively analyse Venezuelan government speeches at the United Nations General Assembly (

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

Zoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Impacts of historical land cover changes on carbon stocks in the Itacaiúnas River Basin, eastern Amazon

Frontiers in Forests and Global Change
Quantifying the long-term impacts of land use and land cover (LULC) change on carbon stocks is critical for guiding climate change mitigation strategies in tropical forest frontiers. In this study, we assessed the spatially explicit carbon balance of the

Molecular Profiling of Genes Associated With Methylphenidate Pathway Therapy and Discovery of New Variants in Amazonian Amerindian Populations

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, Volume 201, Issue 4, Page 291-299, June 2026.
ABSTRACT In Attention Deficit Hyperactivity Disorder (ADHD), methylphenidate is one of the most widely used drugs, in which patient response significantly impacts prognosis. This study aimed to characterize the molecular profile of 10 genes associated with methylphenidate therapy.

Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

Unveiling the Global Linnean Shortfall in Leptophlebiidae (Ephemeroptera, Insecta): Historical Trends and Conservation Implications

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT Understanding how many species exist on Earth is a fundamental yet challenging question in biology, with significant implications for biodiversity conservation. The Linnean shortfall, or the gap in taxonomic knowledge, remains a major obstacle, particularly in highly diverse groups like insects. This study focuses on the family Leptophlebiidae

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Vanishing Treasures: Climate Change Steals Amazonian Coastal Livelihoods—A Cry from the Frontlines of Marajó Island

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
In our study, we demonstrate how climate change is degrading fisheries and forest resources in Marajó Island's coastal communities, where we found younger residents and urban‐proximate groups express the strongest concerns. We document how warming temperatures and erratic rainfall are threatening traditional livelihoods, food security, and cultural ...
