Antigonococcal Activity and Cytotoxicity Screening of Three Ziziphus Species Indigenous to South Africa

Chemistry &Biodiversity, Volume 23, Issue 7, July 2026.
Ziziphus species in South Africa are widely used to treat gonorrhea; however, to this day, there has been no scientific validation of their ethnomedicinal use. This study tentatively identified phytol, betulin, and hexadecanoic acid to be linked to the observed antigonococcal activity.

Using Nuclear Genomic Data to Address Intractable Relationships and Gene Tree Discordance in an Ancient Group of Gymnosperms (Ephedra, Gnetales)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Low‐copy nuclear genes were used to address the notoriously difficult phylogeny of Ephedra. Additionally, we explored the potential effect of putative paralogy, intra‐locus recombination, and chimeric sequences on phylogenetic estimation. ABSTRACT The evolutionary history of Ephedra L.

Evaluation of the e‐Surveyor Mobile Application for Undertaking Plant Surveys and Predicting Habitat Type

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated the accuracy of the e‐Surveyor mobile application, which includes automated identification for plant species and habitat prediction. We compared species lists collected by citizen scientists using the application in the field with data recorded by expert botanists. Most citizen scientists were able to accurately identify almost half of the

Making the most of scarce biological resources in the desert: Loptuq material culture in Eastern Turkestan around 1900

Journal of Ethnobiology and Ethnomedicine
Background Most fisher-gatherer communities we know of utilized a limited number of natural resources for their livelihood. The Turkic-speaking Loptuq (exonym Loplik, Loplyk) in the Lower Tarim River basin, Taklamakan desert, Eastern Turkestan (Xinjiang),

Severe Climate‐Driven Range Contraction of Taverniera abyssinica A. Rich, an Endangered and Locally Popular Medicinal Plant in Ethiopia

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Taverniera abyssinica, a critically endangered Ethiopian medicinal plant, faces severe habitat loss due to climate change. Using ensemble species distribution models (BRT, RF, GAM, GLM), we predict an 83.2% net reduction in suitable habitat under future climate scenarios.

Moving beyond environmental filtering hypotheses: Deciphering the drivers of congeneric plant introductions in an oceanic archipelago

Ecography, Volume 2026, Issue 7, July 2026.
Understanding why only some species succeed in naturalizing and invading ecosystems has intrigued scientists since Darwin's time. The pre‐adaptation hypothesis posits that introduced species closely related to natives, therefore ecologically similar, are more likely to establish than others.

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

Ecography, Volume 2026, Issue 7, July 2026.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 935-942, July 2026.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.
