Comprehensive tree assessments for prioritising conservation action in Mesoamerica

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1813-1823, November 2025.
Tree species are of ecological and social importance globally. Mesoamerica has a diverse tree flora, and the region has experienced major changes in natural habitats due to human activities. In this study, for the first time, we assessed the conservation status of the region's tree species and found that 46% of trees in the region are at risk of ...

Assessment of Essential Nutrients, Bioactive Compounds, and Antioxidant Activity in the Leaves and Fruits of Chinese Olive (Canarium album (Lour.) DC.) Cultivars

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
Key Findings: Analysis of 13 Chinese olive cultivars revealed significant genotypic variations in their profiles of essential nutrients, bioactive compounds, and antioxidant activity. Correlation analysis showed leaf calcium/nitrogen reduced flavonoid accumulation, while fruit calcium enhanced phenolics/alkaloids synthesis, with flavonoids identified ...

Sources of variation in plant chemical diversity: Lessons from Malagasy Ficus

open access: yesAmerican Journal of Botany, Volume 112, Issue 9, September 2025.
Abstract Premise Plants produce a tremendous variety of secondary compounds that are crucial to interspecific and intraspecific interactions and for adaptation to environmental changes. This chemical diversity has been attributed to multiple factors, including interactions with herbivores or pollinators, tissue‐specific needs, and evolutionary ...

Boswellia oropedionis (Burseraceae) sp. nov., a frankincense tree from Socotra, and notes on B. ameero and B. bullata

open access: yesNordic Journal of Botany, Volume 2025, Issue 9, September 2025.
The new species Boswellia oropedionis Thulin and M.H.Weber is described, illustrated by photographs and mapped. This tree is only known from a small population growing on level limestone on the Qatariyah plateau in southern Socotra and is the twelfth endemic species of Boswellia from the Socotra archipelago. It differs from B.

Legacy of the Lost and Pressure of the Present: Malagasy Plant Seeds Retain Megafauna Dispersal Signatures but Downsize Under Human Pressure

open access: yesEcology Letters, Volume 28, Issue 9, September 2025.
Using structural equation models, we show that Malagasy assemblages with higher human pressure have smaller maximum seed sizes, especially through downsizing of extant frugivores. Furthermore, among assemblages with ‘mega‐seeded’ plants (i.e., seeds that cannot be swallowed by any extant Malagasy frugivore), larger seed sizes are associated with larger
