Biogeography of Australian Camphorosmeae and Diversification in Climatic Space and Across Arid Habitat Types.

This study investigates the biogeography of the Australian Camphorosmeae (Amaranthaceae ) lineage and how it relates to shifts in climatic niche and habitat types. Building on previous research and data resources, we integrate molecular phylogenetics, bioclimatic data and biogeographical models to deepen our understanding of the diversification and adaptation of this group across Australia's diverse landscapes in relation to palaeoclimatic changes. For 159 species representing 12 genera, georeferenced distribution points were used to define the most informative bioclimatic variables using principal component analysis.

Global distribution, climatic preferences and photosynthesis-related traits of C eudicots and how they differ from those of C grasses.

C₄ is one of three known photosynthetic processes of carbon fixation in flowering plants. It evolved independently more than 61 times in multiple angiosperm lineages and consists of a series of anatomical and biochemical modifications to the ancestral C pathway increasing plant productivity under warm and light-rich conditions. The C lineages of eudicots belong to seven orders and 15 families, are phylogenetically less constrained than those of monocots and entail an enormous structural and ecological diversity.

Pleistocene dynamics of the Eurasian steppe as a driving force of evolution: Phylogenetic history of the genus (Brassicaceae).

is a model plant genus of the Brassicaceae closely related to . To disentangle its biogeographical history and intrageneric phylogenetic relationships, 282 individuals of all five currently recognized species were genotyped using a restriction digest-based next-generation sequencing method. Our analysis retrieved two main lineages within that split .

A story from the Miocene: Clock-dated phylogeny of L. (Sisymbrieae, Brassicaceae).

Morphological variability and imprecise generic boundaries have hindered systematic, taxonomical, and nomenclatural studies of L. (Brassicaceae, Sisymbrieae DC.).

The phylogeographic history of Krascheninnikovia reflects the development of dry steppes and semi-deserts in Eurasia.

Constituting one of Earth's major biomes, steppes are characterised by naturally treeless extra-tropical vegetation. The formation of the Eurasian steppe belt, the largest steppe region in the world, began in Central Asia during the Neogene. In the glacial stages of the Pleistocene, steppe displaced forest vegetation, which in turn recolonised the area during the warmer interglacial periods, thus affecting the distribution of plants adapted to these habitats.

Zero Intercalary Plates in Parvodinium (Peridiniopsidaceae, Peridiniales) and Phylogenetics of P. elpatiewskyi, comb. nov.

Parvodinium elpatiewskyi, comb. nov., is a common freshwater dinophyte without intercalary plates and with various spines on hypothecal sutures.

They are young, and they are many: dating freshwater lineages in unicellular dinophytes.

Dinophytes are one of few protist groups that have an extensive fossil record and are therefore appropriate for time estimations. However, insufficient sequence data and strong rate heterogeneity have been hindering to put dinophyte evolution into a time frame until now. Marine-to-freshwater transitions within this group are considered geologically old and evolutionarily exceptional due to strong physiological constraints that prevent such processes.

The Hot Spot in a Cold Environment: Puzzling Parvodinium (Peridiniopsidaceae, Peridiniales) from the Polish Tatra Mountains.

Because of a great variety of remote localities and cold habitats, the Tatra Mountains are home to many freshwater protist lineages. Dinophytes have been subjected to a number of studies from this area dating mostly to the first half of the 20th century, but their true diversity remains elusive until today. We collected water tow samples at five lakes in the Tatra Mountains in order to establish monoclonal strains.

Molecular phylogenetics of dinophytes harboring diatoms as endosymbionts (Kryptoperidiniaceae, Peridiniales), with evolutionary interpretations and a focus on the identity of Durinskia oculata from Prague.

Peridinialean dinophytes include a unique evolutionary group of algae harboring a diatom as an endosymbiont (Kryptoperidiniaceae), whose phylogenetic origin and internal relationships are not fully resolved at present. Several interpretations of the thecal plate pattern present in Durinskia oculata currently compete and lead to considerable taxonomic confusion. Moreover, it is unclear at present whether the species is restricted to freshwater habitats, or occurs in the marine environment as well.
