Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.Evaluating Piper marginatum essential oils across three Brazilian biomes reveals significant chemical and antimicrobial variations driven by seasonal and regional factors. Sixty compounds are identified, including a novel (Z)‐phenylpropanoid reported for the first time. Multivariate analysis correlates environmental stressors with specialized metabolic

Ibis, Volume 168, Issue 4, Page 1572-1588, October 2026.Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Diel net CO2 exchange of carnivorous Pinguicula is consistent with low‐level CAM photosynthesis
Plant Biology, Volume 28, Issue 6, Page 1813-1819, October 2026.In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

CYTOLOGIA, 1976 From a comparison of the chromosome numbers of different species, it appears that 11 is the basic number of Peperomia and 12 of Piper. Variation in the reports of chromosome number of the same species may be due to occurrence of chromosomal biotypes.The trend of evolution in the two genera (Peperomia and Piper) appear different, numerical and ...

Proteomic profile of Piper tuberculatum (Piperaceae) [PDF]
Brazilian Journal of Biology, 2017 Abstract Piper tuberculatum (Piperaceae) is a species that accumulates especially amides as secondary metabolites and several biological activities was previously reported. In this article, we report a proteomic study of P. tuberculatum. Bidimensional electrophoresis (2D SDS-PAGE) and mass spectrometry (ESI-Q-TOF) were used in this study.

Environmental and Evolutionary Correlates of Extinction Risk in a Global Biodiversity Hotspot
Ecology and Evolution, Volume 16, Issue 9, September 2026.We show that larger genera have a greater number of threatened and near‐threatened species, and that extinction risk is uncoupled with evolutionary history (diversification, speciation, extinction rates and lineage age). The decoupling of diversification rates and lineage age with current extinction risk suggests drivers of extinction risk are ...
