Extreme environments in a world of new extremes

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Extreme environments, whether defined by climate, soils, or disturbance, at landscape or micro‐scales, are prevalent across Earth's surface and have long served as crucibles for ecological and evolutionary insights. Many foundational theories were developed in deserts, cliffs, ultramafic soils, and other harsh systems.

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

A Complete Generic Phylogeny of Malpighiaceae Inferred from Nucleotide Sequence Data and Morphology [PDF]

open access: yes, 2010
Premise of the study: The Malpighiaceae include ∼1300 tropical flowering plant species in which generic definitions and intergeneric relationships have long been problematic.

Sequencing Angiosperm Plastid Genomes Made Easy: A Complete Set of Universal Primers and a Case Study on the Phylogeny of Saxifragales [PDF]

open access: yesGenome Biology and Evolution, 2013
Plastid genomes are an invaluable resource for plant biological studies. However, the number of completely sequenced plant plastid genomes is still small compared with the vast number of species. To provide an alternative generalized approach, we designed a set of 138 pairs of universal primers for amplifying (termed "short-range PCR") and sequencing ...

First steps towards a floral structural characterization of the major rosid subclades [PDF]

open access: yes, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...

Extrapolating demography with climate, proximity and phylogeny: approach with caution [PDF]

open access: yes, 2016
Plant population responses are key to understanding the effects of threats such as climate change and invasions. However, we lack demographic data for most species, and the data we have are often geographically aggregated.

Placing Nothophylica piloburmensis from Cretaceous amber into the angiosperm phylogeny

open access: yesTAXON, Volume 74, Issue 4, Page 933-937, August 2025.
Abstract Recently, we redescribed an amber inclusion from mid‐Cretaceous Kachin amber of Myanmar, previously assigned to the extant genus Phylica in Rhamnaceae (core eudicots), and placed it in a new fossil‐genus, Nothophylica. Based on our reconstructions, we identified new floral features and instead suggested affinities within magnoliids, especially

Early eudicot reproductive structure: Fruit and flower morphology of Ranunculaecarpus Samyl. from the Early Cretaceous of eastern Siberia

open access: yesActa Palaeobotanica, 2018
Floral and fruit morphology of the early eudicot Ranunculaecarpus quinquecarpellatus Samyl. is described based on details from sectioning and microscopy of the permineralized type material from the Albian Buor-Kemyus Formation of the Zyryanka coal basin.

Synorganisation without organ fusion in the flowers of Geranium robertianum (Geraniaceae) and its not so trivial obdiplostemony [PDF]

open access: yes, 2017
Background and Aims Synorganisation of floral organs, an important means in angiosperm flower evolution, is mostly realized by congenital or post-genital organ fusion.
