Chemical Profiling and Biological Activity of Copaiba Oil‐Resin Samples and Development of HPLC‐DAD Method for the Analysis of β‐Caryophyllene

open access: yesBiomedical Chromatography, Volume 40, Issue 5, May 2026.
ABSTRACT The Copaifera species are traditionally used for their anti‐inflammatory, antiseptic and healing properties. The objective of this study was to compare the chromatographic profiles of seven samples of copaiba oil‐resin with respect to chromatographic and physicochemical properties and to evaluate their biological activities.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Land Cover Change Drives River Flow Modifications in Central Chile

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
This study examines the combined effects of land cover change and ENSO on streamflow dynamics in four coastal catchments of central Chile, using a 45‐year (1979–2023) dataset of remote sensing and hydroclimatic data. Conclusions Native forest loss reduced summer flows and PP–Q relationship; preserved forests enhanced resilience.

Modelling the Black Carbon Variability and Dynamics in Almaty, Kazakhstan, During Winter and Summer Seasons

open access: yesMeteorological Applications, Volume 33, Issue 3, May/June 2026.
The study investigates the seasonal transport of black carbon (BC) from Almaty, Kazakhstan, to adjacent mountain areas. The radiative effects associated with BC are evaluated at the surface, within the atmosphere, and at the top of the atmosphere. ABSTRACT Large cities with poor air quality can affect surrounding areas through pollutant transport and ...

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a
