The phytochemical profile and biological activities of Cistus creticus leaf ethanolic extracts show strong seasonal variation. Spring extracts contain the highest phenolic levels with potent antioxidant and anti‐inflammatory effects, while summer extracts are richest in flavonoids and exhibit the greatest sun protection factor value and enzyme ...

3-24 Cistaceae, rock-rose family [PDF]
A family of low shrubs or wiry herbs, there are only 200 or so species worldwide in eight genera. Leaves are entire and simple, and usually alternately arranged. Perfect flowers are hypogynous and regular, but for the calyx, which has two reduced sepals.

This study explores the phytotoxicity of Pinus pinea needle extracts and metabolites to evaluate their potential for controlling dicotyledonous weeds. A strategy based on GC–MS, NMR, and optical methods revealed an array of aromatic compounds which are of crucial interest for phytochemical research. Hence, a bio‐guided purification led to the isolation

Abstract Premise Humans have used fire to manage landscapes for millennia, but this use of fire is declining in many ecosystems. Understanding how plants respond to these changes is key to predicting ecosystem resilience and impacts on services such as biodiversity and carbon sequestration. However, many ecosystems lack data on plant fire responses.

Phylogenomic Evidence of Fire Regime Changes: The Case of a Resprouting Juniper
We propose that fire‐adaptive traits, such as lignotuber resprouting, can serve as proxies to estimate fire regime shifts. We estimated the origin of lignotuber resprouting in the Iberian Juniperus oxycedrus complex. By doing so, we provide new insights into the assembly of the Mediterranean biome.

Pollinator choices when selecting flowers for nectar or pollen collection are crucial in determining the effectiveness of pollination services provided to plants. From the plant's perspective, this effectiveness is a phenomenon shaped by factors at both the species‐ (e.g.

Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex evolutionary history for the order, including localised phylogenetic discordances among nuclear loci.

Abstract Community‐wide assembly of plant–pollinator systems depends on an intricate combination of biotic and abiotic factors, including heterogeneity among pollinators in thermal biology and responses to abiotic factors. Studies on the thermal biology of pollinators have mostly considered only one or a few species of plants or pollinators at a time ...
