Evaluation of Agave angustifolia as a Sustainable Alternative to Synthetic Pesticides: Phytochemical Composition and Multi‐Trophic Bioactivity

open access: yesFlavour and Fragrance Journal, EarlyView.
The pesticidal potential of Agave angustifolia by assessing its anti‐nematic, antimicrobial, and insecticidal activities, alongside phytochemical profiling. ABSTRACT Plant diseases caused by fungi, bacteria, nematodes, and viruses contribute significantly to annual crop losses and economic hardship. Reliance on chemical pesticides, over a thousand used

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

open access: yesFlavour and Fragrance Journal, EarlyView.
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.

Morphological and phenological shifts in semiarid grasses paralleled climate and land use changes

open access: yesFrontiers in Environmental Science
Plants respond to climate change through shifts in traits such as height, leaf width, and flowering time. However, little is known about how grass species in semiarid ecosystems are responding. In this study, we tested three hypotheses: (1) grass species

Future Range Shifts and Diversity Patterns of Antarctic Lecideoid Lichens Under Climate Change Scenarios

open access: yesGlobal Change Biology Communications, EarlyView.
Modeling of current and future spatial distribution of Antarctic lecideoid lichens shows that warming will strongly increase the potential habitat. Under three climate‐change scenarios, most fungal and algal partners are projected to expand inland. Overall, climate change drives widespread range shifts and promotes colonization of interior Antarctica ...

Manual of tropical bryology [PDF]

open access: yes, 2003
Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often

A new combination and typification of Pouzolzia peteri Friis (Urticaceae)

open access: yesNordic Journal of Botany, EarlyView.
Pouzolzia peteri, a lesser‐known species from the African continent, is currently classified as a member of the genus Pouzolzia. However, based on the morphological characteristics of its male flowers and leaf venation, its transfer to the genus Gonostegia is proposed.

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

The native flora of the Redberry Lake Biosphere Region (Saskatchewan, Canada): taxonomy, biogeography, habitats and conservation

open access: yesNordic Journal of Botany, EarlyView.
This study reports for the first time a checklist of native vascular plants and provides a comprehensive analysis of the flora of the Redberry Lake Biosphere Region (RLBR) in the province of Saskatchewan, Canada. To complete an inventory of the regional flora, I conducted intensive field investigations during 2010–2025 and employed detailed examination
