A fern thought to grow on trees still keeps a root on the ground

The Aspleniaceae is a family of ferns, some of which are terrestrial and some of which are epiphytes. A new study has found a rarity, a hemiepiphyte.

RAD-seq and morphology clarify evolutionary relationships in Eurasian bee orchids

Eurasian bee orchids (Ophrys, Orchidaceae) have become the most popular model system for studying reproduction via insect-mediated pseudo-copulation and for exploring the consequent, putatively...

Evolution of Rainbow rockcress highlights Anatolia as a cradle of biodiversity

Phylogenetic and demographic analyses were employed to shed light on the species boundaries, evolutionary history and species diversity of genus Aubrieta (Brassicaceae). DNA sequence...

Deep sequencing coming for three taxa at key phylogenetic nodes

Following his recent visit to Cambridge, Josh Mylne (UWA) will be collaborating with Jill Harrison (Cambridge) and Kingsley Dixon (Perth Botanic Garden) to sequence...

Australia’s national flower is an invasive species – even in Australia

How do you control a problem like Acacia pycnantha? First, figure out what you are dealign with.

Free paper — Genome size in Anthurium evaluated in the context of karyotypes and phenotypes

Little is known about the genome of Anthurium other than chromosome observations, which frequently indicate supernumerary (“B”) chromosomes. New genome size estimates for 34...

Free paper — Identification of Stylosanthes guianensis varieties using molecular genetic analysis

Molecular genetic diversity and population structure analysis were used to clarify the controversial botanical classification of Stylosanthes guianensis.  In this paper, the accessions were...

Free paper — Dividing without centrioles

Innovative MTOCs organize mitotic spindles in bryophytes, the earliest extant lineages of land. Triple staining of γ-tubulin, microtubules, and nuclei here reveal that three types of...

X-ray dose limits for microscopy lower than we thought

Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.

Habitat partitioning through reproductive interference in Geranium

We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they...

Improving overyielding in legume-based mixtures

A major challenge when supporting the development of intercropping systems remains the design of efficient species mixtures. The ecological processes that sustain...

The Oaks of the North Are Unexpectedly Well-Defended

Normally you would expect plant defences to increase, the closer you get to the equator. This is where insect life is more...
