Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 702-715, May 2026.
Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Application of chemometric analysis to infrared spectroscopy for the identification of wood origin [PDF]

open access: yes, 2016
Chemical characteristics of wood are used in this study for plant taxonomy classification based on the current Angiosperm Phylogeny Group classification (APG III System) for the division, class and subclass of woody plants.

The role of Alpine botanical gardens in integrating germplasm bank collections and mission

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.
This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

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 ...

Phylogenetic Relationships in Phoradendreae (Viscaceae) Inferred from Three Regions of the Nuclear Ribosomal Cistron. II. The North American Species of Phoradendron [PDF]

open access: yes, 2000
A parsimony analysis based on sequences from the ITS region and two partitions of the 26S subunit of nuclear ribosomal DNA was used to infer phylogenetic relationships among the North American species of Phoradendron.

Phylogeny, systematics and evolution of mimicry patterns in Neotropical limenitidine butterflies

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The most comprehensive phylogeny for Adelpha reveals that it is not monophyletic, supporting the description of the new genus Adelphina for the alala‐group. The rate of mimicry evolution increases towards the tropics, consistent with the hypothesis of stronger biotic interactions near the equator.

Phylogenetic relationships in Nuphar (Nymphaeaceae): Evidence from morphology, chloroplast DNA, and nuclear ribosomal DNA [PDF]

open access: yes, 1999
The genus Nuphar consists of yellow-flowered waterlilies and is widely distributed in north-temperate bodies of water. Despite regular taxonomic evaluation of these plants, no explicit phylogenetic hypotheses have been proposed for the genus.

The Leaf Length-Width Method Is Applicable to Compound Leaves of Diverse Forms

open access: yesAgriculture
To estimate leaf area, the length-width method, also called the Montgomery equation, has been widely used. It is an empirical formula stating that within a given species, the area of a leaf is proportional to the product of its length and width. Although
