A conspectus of the genus Cherleria (Minuartia s.l., Caryophyllaceae)

2017

Abstract: Minuartia s.l. (Caryophyllaceae) is polyphyletic, with its species belonging to eleven major clades, all of which have been recognized at the generic rank. Cherleria is one of these segregate genera, based on the Linnaean species Cherleria sedoides. Its centre of diversity is on the Balkan Peninsula, but species also occur in the European and North American high mountains and in the Arctic. The species of Cherleria show ecological, especially substrate, differentiation and multiple colonisations of alpine habitats. We make new combinations for the 17 (of 20) taxa in Cherleria that do not yet have Cherleria names and provide a key to all species of the genus. Citation: Moore A. J. …

Maximum polyphyly: Multiple origins and delimitation with plesiomorphic characters require a new circumscription of Minuartia (Caryophyllaceae)

An AFLP clock for the absolute dating of shallow-time evolutionary history based on the intraspecific divergence of southwestern European alpine plan…

2009

The dating of recent events in the history of organisms needs divergence rates based on molecular fingerprint markers. Here, we used amplified fragment length polymorphisms (AFLPs) of three distantly related alpine plant species co-occurring in the Spanish Sierra Nevada, the Pyrenees and the southwestern Alps/Massif Central to establish divergence rates. Within each of these species (Gentiana alpina, Kernera saxatilis and Silene rupestris), we found that the degree of AFLP divergence (D(N72)) between mountain phylogroups was significantly correlated with their time of divergence (as inferred from palaeoclimatic/palynological data), indicating constant AFLP divergence rates. As these rates d…

The evolution of substrate differentiation inMinuartiaseriesLaricifoliae(Caryophyllaceae) in the European Alps: In situ origin or repeated colonizati…

2013

Premise of the study Substrate specialization is often considered an important factor in evolutionary diversification. A classic example of divergence related to different substrate types is the dichotomy between calcicole and calcifuge plants on calcareous and siliceous substrates as found in the European Alps. When closely related species with contrasting substrate preferences are found in the same area, it is generally hypothesized that they diverged where they now occur. However, it is possible that Alpine edaphic diversity instead allows the coexistence of related species whose edaphic differentiation took place deeper in the phylogeny, in some other part of the range of their clades. …

A new combination in Mononeuria (Caryophyllaceae)

The nomenclatural change Mononeuria caroliniana comb. nov. is proposed on the basis of molecular phylogenetic results analyzing the nuclear internal transcribed spacer.

What is the origin of the Scottish populations of the European endemic Cherleria sedoides (Caryophyllaceae)?

2015

Cherleria sedoides L. (Minuartia sedoides (L.) Hiern) is a montane perennial which, with some species in Minuartia sect. Spectabiles, is more closely related to Scleranthus than to other Minuartia species and is therefore best restored to the reinstated and redefined genus Cherleria. Reconstruction of the ancestral area of the clade containing C. sedoides suggests that it evolved in the Alps or the Balkan peninsula. The species now has an unusual distribution, being present in the mountains of southern Europe and Scotland but absent from the Arctic. Three historical scenarios that might have led to the presence of the species in Scotland are outlined and tested by a molecular analysis compa…

Data from: The origin of the serpentine endemic Minuartia laricifolia subsp. ophiolitica by vicariance and competitive exclusion

2013

Serpentine soils harbour a unique flora that is rich in endemics. We examined the evolution of serpentine endemism in Minuartia laricifolia, which has two ecologically distinct subspecies with disjunct distributions: subsp. laricifolia on siliceous rocks in the western Alps and eastern Pyrenees and subsp. ophiolitica on serpentine in the northern Apennines. We analysed AFLPs and chloroplast sequences from 30 populations to examine their relationships and how their current distributions and ecologies were influenced by Quaternary climatic changes. Minuartia laricifolia was divided into four groups with a BAPS cluster analysis of the AFLP data, one group consisted only of subsp. ophiolitica, …

Flagship species of the Pieniny NP. protected ex situ at PAS BGCBDC seed bank at WARSAW-POWSIN

2014

Pieniny Mts. are important biodiversity hotspot in Central Europe. According to Pieniny National Park Long Term Conservation Plan 2000-2020 small, isolated populations of some of Pieniny NP flagship species can become extinct till 2020. That is why their ex situ preservation at seed bank is justified and reasonable as supplement of active and passive in situ conservation measures carried out by National Park staff. PAS Botanical Garden – Center for Biological Diversity Conservation at Warsaw-Powsin has a long tradition of cooperation with Pieniny National Park (S Poland). This article focuses on the actions undertaken during EU funded conservation project: “Ex situ conservation of native, t…
