Abstract. A rare, new tetraploid Atriplex, restricted to two populations ∼30 km apart in arid Western Australia, is supported as a distinct species by morphological and molecular evidence. Genetic analyses using amplified fragment length polymorphisms (AFLPs) showed significant genetic divergence between the two populations. In contrast, an ordination based on elliptic Fourier descriptors for leaf and bracteole shape did not identify any consistent morphological differentiation. Although the… 

Cryptic species in the Andean hemiparasite Quinchamalium chilense (Schoepfiaceae: Santalales)

It is hypothesize the existence of two cryptic species within Quinchamalium chilense (Mountain and Matorral–Desert) that correspond to genetic, climatic, and morphological differences.

High nuclear genetic differentiation, but low chloroplast diversity in a rare species, Aluta quadrata (Myrtaceae), with a disjunct distribution in the Pilbara, Western Australia

The high genetic differentiation among geographically isolated locations of A. quadrata is consistent with limited contemporary connectivity among the geographically separated locations, although lack of chloroplast haplotype variation indicates that limited connectivity has occurred more recently and is not due to historical isolation.

Genetic Diversity and Structure in the Philippine Rafflesia lagascae Complex (Rafflesiaceae) Inform Its Taxonomic Delimitation and Conservation

Patterns of genetic diversity of staminate and pistillate Rafflesia flowers growing on the same Tetrastigma host plants indicate that the R. lagascae complex is monoecious and that host plants are regularly infected by multiple Raffleia plants.

Genetic Diversity and Conservation Units: Dealing With the Species-Population Continuum in the Age of Genomics

It is recommended that genomic data should be interpreted conservatively when formally naming species, there should be stronger impetus and a more uniform approach to identifying clearly justified intraspecific units, and guidelines be developed for recognising and labelling intra-specific data that align with best scientific practice.

A molecular journey in conservation genetics

The author shares his journey of discovery in genetics and genomics, and their application in conservation of plants through understanding evolutionary history, population genetics of rare and threatened species, molecular taxonomy, fragmentation and the role of pollen dispersal.

Methodology for the estimation of land suitability for Atriplex L. [Amaranthaceae Juss. (s.l.)] cultivation in arid and semi-arid regions

Abstract Atriplex includes species with multiple purposes such as biomass for energy production, for bioremediation of soils contaminated with metals, or soil conservation. In Chile, 29 Atriplex

Reversing extinction trends: new uses of (old) herbarium specimens to accelerate conservation action on threatened species.

Herbarium specimens offer material to foster species recovery, ecosystem restoration, and de-extinction, and these elements should be used in conjunction with machine learning and citizen science initiatives to mobilize as large a force as possible to counter current extinction trends.

Taxonomic delimitation and the evolutionary history of the Australasian Lautusoid group of Senecio (Asteraceae)

The delimitation and evolutionary history of the Australasian Lautusoid group of Senecio (Asteraceae; Senecioneae) is compared to other delimitation studies of cryptic or complex species.



Significant population genetic structure detected for a new and highly restricted species of Atriplex (Chenopodiaceae) from Western Australia, and implications for conservation management

This work investigates the structure of genetic variation within populations and subpopulations of this taxon using nuclear microsatellites and proposes management recommendations for this potentially new species in light of its highly structured genetic variation.

Morphological and molecular evidence supports the recognition of a new subspecies of the critically endangered Pityrodia scabra (Lamiaceae)

A combined approach utilising highly variable, non-coding chloroplast gene regions and morphological data is used here to help delimit cryptic taxa in the rare Western Australian species Pityrodia scabra, which is of conservation concern because it is currently known only from a few, isolated populations.

Evidence for convergent evolution among phylogenetically distant rare species of Tetratheca (Elaeocarpaceae, formerly Tremandraceae) from Western Australia

Cladistic analysis of nrDNA internal transcribed spacer and cpDNA trnL-trnF sequences from a range of Tetratheca species indicates that T. aphylla, T. harperi and T. paynterae belong to three separate evolutionary lineages and that the endemism displayed among these taxa to small, disjunct ranges within the same geographic area, is a result of in situ speciation due to historical fragmentation.

Genetic diversity and multiple origins of polyploid Atriplex nummularia Lindl. (Chenopodiaceae)

Clustering patterns based on Bayesian analyses suggested that the polyploid subspecies of A. nummularia have multiple origins, and these findings support the taxonomic separation of the two subspecies.

Cryptic divergent lineages of Pultenaea pauciflora M.B. Scott (Fabaceae: Mirbelieae) exhibit different evolutionary history

Genetic structure among disjunct population groups of Pultenaea pauciflora was assessed to determine the evolutionary history of this species as a basis for conservation management strategies and two highly divergent genetic entities with strong geographical structuring were revealed.

Evolutionary diversification and geographical isolation in Dubautia laxa (Asteraceae), a widespread member of the Hawaiian silversword alliance.

Results indicate that geographical separation has aided diversification in D. laxa, whereas ecologically associated morphological differences are not associated with neutral genetic differentiation, suggesting that, despite the stunning ecological adaptation observed, geography has also played an important role in the Hawaiian silversword alliance plant adaptive radiation.

Extensive sympatry, cryptic diversity and introgression throughout the geographic distribution of two coral species complexes

DNA sequence data from 12 genomic regions are used to characterize two widespread species complexes in the coral genus Acropora to demonstrate the presence of at least six widespread cryptic species within these two morphospecies complexes.

Molecular phylogeny of Atripliceae (Chenopodioideae, Chenopodiaceae): Implications for systematics, biogeography, flower and fruit evolution, and the origin of C4 photosynthesis.

UNLABELLED PREMISE OF THE STUDY Atripliceae (Chenopodiaceae), including Atriplex (300 spp.) as the largest genus of the family, are an ecologically important group of steppes and semideserts

When rare species become endangered: cryptic speciation in myrmecophilous hoverflies

It is suggested that cryptic speciation is apt to evolve in species, such as myrmecophiles, endoparasites and koinobiont parasitoids, whose life-styles result in strong selection on their physiological or behavioural characters.

Divergence in the chloroplast genome and nuclear rDNA of the rare Western Australian plant Lambertia orbifolia Gardner (Proteaceae)

The divergence of the Narrikup region suggests that the disjunction in the species distribution has been present for a long time and the two regions represent separate evolutionary lineages.
