Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

Nordic Journal of Botany, Volume 2026, Issue 11, November 2026.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Chamaecrista marinasilvae sp. nov. (Leguminosae, Caesalpinioideae): a threatened new species from the deforestation frontier of the Brazilian Cerrado

Nordic Journal of Botany, Volume 2026, Issue 11, November 2026.
During a field expedition to the Jalapão region (Tocantins State, Brazil), a morphologically distinct specimen was collected and identified as a new species, Chamaecrista marinasilvae. Further herbarium investigations revealed additional collections of this taxon from the same state that had been misidentified as Chamaecrista juruenensis.

From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

PLANTS, PEOPLE, PLANET, Volume 8, Issue 6, Page 2055-2060, November 2026.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...

Microbiological Quality and Analysis of Escherichia coli Resistance to Antibiotics in Beaches: Evaluating Anthropic Influence in Surface Waters in Brazil

Water Environment Research, Volume 98, Issue 11, November 2026.
Anthropic activities and untreated wastewater promote the dissemination of antibiotic‐resistant E. coli (83.3% of isolates) in coastal waters, increasing environmental contamination and public health risks. ABSTRACT Antimicrobial resistance is a problem for public health.

Environmental Justice in the Brazilian Coastal Food Systems: Policies, Institutions, and Knowledges on Small‐Scale Fishers and Energy Development

World Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

Microclimate, Vegetation, and Soil Response to Micro‐Zonal Solar Photovoltaic Patterning in a Humid Sub‐Tropical Agrivoltaic Grazing System

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Agrivoltaic grazing systems, or the integration of solar photovoltaic (PV) energy generation with livestock grazing, are the most common form of multi‐use solar energy in the United States and much of the world. However, there is a substantial gap in our understanding of the ecological impacts of combining PV and grazing in these novel ...

Mapping diversity through geographical, environmental and attribute spaces

Methods in Ecology and Evolution, Volume 17, Issue 11, Page 3084-3094, November 2026.
Abstract Understanding biodiversity patterns requires integrating information across the interrelated dimensions that organize life. Species occupy specific regions in geographic space, respond to environmental conditions and vary within attribute (or trait) spaces that are shaped by their ecological and evolutionary histories.
