How important is meat to a curious carnivorous plant?

Drosophyllum lusitanicum, also known as the Portuguese sundew or dewy pine, is unusual even for carnivorous plants in that it lives in dry environments. Typically, carnivorous plants live in nutrient-poor wetlands, so does it really gain much from carnivory?

Investigating the diet of carnivorous plants

Earlier this year we reported on how it looked like bladderworts were farming their food, as much as hunting it. A paper submitted before those came out adds to the story, by examining the 'trophic level' of bladderwort and butterwort prey.

Mixotrophy in boreal pyroloids does not vary with tissue age or light level

Pyroloid mixotrophy does not respond plastically to ageing or to light level. This contrasts with the usual view of a convergent evolution with orchids.

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...

Saprotrophic fungi and fully mycoheterotrophic orchids

This study identifies saprotrophic mycorrhizal fungi for seven mycoheterotrophic orchid species growing in four humid and warm subtropical forests in Taiwan

Mutualistic ants contribute to bromeliad nutrition

It is more advantageous for some bromeliads to obtain ant-derived nutrients via its roots than to eat them.

Ants mediate plant reproductive traits

The selection of floral and reproductive traits is influenced by the plant’s abiotic environment, florivores and pollinators. Leroy et al.  show that mutualistic associations with...

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...

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