Remote tropical island colonization does not preclude symbiotic specialists

For symbiotic organisms, their colonization and spread across remote oceanic islands should favour generalists. Plants that form obligate symbiotic associations with microbes dominate island...

The secret to conserving an endangered orchid is in the soil

A study of orchids shows the secret to conservation isn't in the plants you can see, but the fungi you can't.

Plant records: Can a plant be too trusting?

Name: Orchids Scientific name: Family: Orchidaceae Known for: Beauty, epiphytism, providing vanilla flavouring, tiny seeds, mycorrhizae, deceptive pollination, mycoheterotrophy, medicinal usage, vegetating Krakatoa… Record broken: The world’s...

Plants enjoying the high life

Plants on Plants – The Biology of Vascular Epiphytes by Gerhard Zotz. Springer 2016. Gerhard Zotz’s The biology of vascular epiphytes is part of...

Diuris population genomics

Conservation of orchid species (Orchidaceae) can be challenging, particularly for a small Diuris group of four species from southeastern Australia. To determine best conservation...

An orchid with a partially mycoheterotrophic taste for truffles

Partially mycoheterotrophic nutrition is a widespread trophic strategy in green-leaved Orchidaceae species in forest habitats. Owing to the light limitation of their habitats, many...

It’s not easy being green: ecophysiological patterns of mycoheterotrophy in ectomycorrhizal Orchidaceae and Ericaceae

Autotrophy, though common among plants, isn’t the only way plants make a living. Some plants have lost all photosynthetic abilities and instead rely on...

Sexual and asexual reproduction in a mycoheterotrophic orchid

Sexual reproduction is common within Orchidaceae, though apomixis does occur in some genera allowing them to produce seeds that are clones of the mother....

Strengthening the taxonomic backbone of Thai orchid conservation

Pedersen et al. present analyses of morphometric and AFLP data from populations of Geodorum (Orchidaceae) – a study conducted in preparation of the Flora...

Orchid conservation: further links

Fay introduces the often complex interactions of orchids with mycorrhizal fungi, pollinators and host trees, considering also threats from human utilization and changing land...

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...
