Physicochemical study of Delphinium denudatum Wall (Ranunculales: Ranunculaceae) and their antioxidant activity [PDF]

open access: yesBrazilian Journal of Biological Sciences, 2019
The drug jadwar known as Delphinium denudatum Wall (Ranunculales: Ranunculaceae), the jadwar consist of dried tuberous roots of D. denudatum. An annual glabrous or slightly downy herbs found is Western Himalayas from Kumaon to Kashmir at altitudes of 3,000 m to 4,500 m specially on grassy slopes.

Pollen malformation and ploidy levels in Ranunculus grex parnassiifolius [PDF]

open access: yes, 2011
Se presenta un estudio sobre la malformación polínica en Ranunculus grex parnassiifolius, un complejo poliploide cuya distribución va desde las montañas del noroeste de la Península Ibérica hasta la mayor parte de los macizos alpinos.

How have advances in comparative floral development influenced our understanding of floral evolution? [PDF]

open access: yes, 2015
Evolutionary developmental biology has come to prominence in the past two decades, in both the plant kingdom and the animal kingdom, particularly following the description of homeotic genes linked to key morphological transitions.

Seed Shape Diversity in families of the Order Ranunculales

open access: yesPhytotaxa, 2019
Seed shape in the order Ranunculales is described with the objective of characterizing the morphological seed types in the families of this order and to establish a correlation between seed shape, plant structure and life style.         Based on previous work in model plants (Arabidopsis thaliana, Lotus japonicus, Medicago truncatula), we have used the

Review of larval food plant associations of the Agaristinae (Lepidoptera: Noctuidae) in Australia

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract The Australian Agaristinae comprises a small group of predominantly diurnal moths with aposematic larvae and adults that are assumed to be unpalatable to most predators. A critical review of the larval food plants of this subfamily based on published records in the literature, together with unpublished records, is presented.

Morphology and angiosperm systematics in the molecular era [PDF]

open access: yes, 2018
Several ways in which morphology is used in systematic and evolutionary research in angiosperms are shown and illustrated with examples: 1) searches for special structural similarities, which can be used to find hints for hitherto unrecognized ...

Evolution of Perianth and Stamen Characteristics with Respect to Floral Symmetry in Ranunculales [PDF]

open access: yesAnnals of Botany, 2007
Floral symmetry presents two main states in angiosperms, namely polysymmetry and monosymmetry. Monosymmetry is thought to have evolved several times independently from polysymmetry, possibly in co-adaptation with specialized pollinators. Monosymmetry commonly refers to the perianth, even though associated androecium modifications have been reported ...

Angiosperm pollen grains from the Cuayuca Formation (Late Eocene to Early Oligocene), Puebla, Mexico [PDF]

open access: yes, 2015
Systematic descriptions and illustrations of the best preserved angiosperm pollen grains (Monocotyledonae or Liliopsida: n= 7 and Dicotyledonae or Magnoliopsida: n= 41) recovered from Cuayuca Formation (late Eocene-early Oligocene), Puebla State ...

Incorporating Genetic Diversity to Optimize the Plant Conservation Network in the Third Pole

open access: yesGlobal Change Biology, Volume 31, Issue 3, March 2025.
Climate change is a major threat to plant survival, and existing protected areas often fail to consider genetic diversity, which is crucial for species adaptation. Our meta‐analysis of plants in the Third Pole region shows that genetic diversity in the area is shaped by climate and landscape factors. To survive, many plants will need to move upward and

Increasing variability in resource supply over time disrupts plant–pollinator interactions

open access: yesEcological Monographs, Volume 95, Issue 1, February 2025.
Abstract Insect–plant interactions are key determinants of plant and insect fitness, providing important ecosystem services around the world—including the Arctic region. Recently, it has been suggested that climate warming causes rifts between flower and pollinator phenology.
