Phylogenetics of Clusia sect. Criuva (Clusiaceae) unveils a new species, reinstates an old name and clarifies sectional circumscription

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Clusia sect. Criuva has long been a taxonomic catch‐all, particularly in the final decades of the 20th century, when misapplications conflated eastern Brazilian taxa with species from the Guiana Shield. We combine herbarium‐based genome skimming, targeted fieldwork, and critical examination of historical literature and types to reassess ...

Taxonomic complexity in the parasitic plant genus Cistanche: Evidence from phylogenomics

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract “Desert hyacinths” (genus Cistanche) are striking parasitic plants of historical and cultural importance that include species traded widely for herbal medicine. Despite the need for robust taxonomy, the application of names in the genus remains confused.

Operational Greenhouse Gas Emissions Inventory of a University Campus in Brazil

open access: yesEnvironmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Climate change mitigation requires robust greenhouse gas (GHG) accounting frameworks capable of identifying major emission sources within institutional systems. Higher education institutions represent complex operational environments characterized by substantial energy demand, transportation activities, and material consumption, all of which ...

Intensified Oxygen Minimum Zone in Response to Both Insolation Maxima and Carbon Dioxide‐Driven Warmth in the Tropical North Atlantic

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Oxygen (O2) is essential for almost all life on Earth, but O2 concentrations are rapidly declining in the oceans under global warming, stressing marine ecosystems and biogeochemical cycles. Numerical model simulations suggest greatly expanded North Atlantic Oxygen Minimum Zones (OMZs) under warm Pliocene conditions, but sparse data limit ...
