A meta-analysis of leaf nitrogen distribution within plant canopies

Leaf N is generally highest in top leaves and decreases with depth in leaf canopies. Although such a gradient contributes to efficient use of...

Being an avid supporter of the importance of plants (I do hope that’s come over quite strongly in my various blog items..?), I’m always...

Impact of an invasive nitrogen-fixing tree on arbuscular mycorrhizal fungi and development of native species

The presence of invasive plants has been identified as a soil disturbance factor, often conditioning the structure and function of soil microorganisms. Despite the...

Conflicting selection on floral traits

Floral traits attracting pollinators may also attract seed predators; however, evidence for conflicting selection on such traits remains scarce. One could expect that such...

NQFF: The five science links you were sharing on Twitter this week

It was close at the top this week for the most shares on twitter one just beat out the other. This week our followers...

No difference in the competitive ability of introduced and native Trifolium provenances when grown with soil biota from their introduced and native ranges

A new biogeographic study published in AoB PLANTS by Shelby et al. tested the evolution of increased competitive ability (EICA) hypothesis—a compelling explanation for...

Silicon enhances cellular defences in root tissues of cotton after pathogen inoculation

Silicon has been shown to enhance the resistance of plants to fungal and bacterial pathogens, however the underlying mechanisms have not been studied in...

The 21st century Prometheus

The full title of Mary Shelley’s acclaimed 1818 novel “Frankenstein” is “Frankenstein, or the Modern Prometheus”. Well, fictional frightening-fellow fabricator Dr Frankenstein may have been the modern Prometheus of his day, but I’ve just chanced upon the 21st century version. Nothing to do with hard-copy science fiction of the late Georgian period, this truly modern Prometheus is science fact-based and exists virtually as an on-line Wiki

The remarkable stomata of horsetails (Equisetum)

Horsetails are an ancient group of land plants that possess many unusual features, including the structure and development of the apertures (stomatal pores) in...

Spore settling velocity to assess moss dispersal rates

The settling velocity of diaspores is a key parameter influencing dispersal ability in wind-dispersed plants but remains largely undocumented in bryophytes. Zanatta et al. measured...

Seed germination is a critical step in the life cycle of flowering plants. Since seeds contain limited reserves, seed germination has to...

Daffodils and Snowdrops react differently to warming seasons

Daffodils and Snowdrops need the right temperatures in a few seasons to germinate. Will a changing climate cause problems?

Changes in How a Plant Breathes Aren’t Always Matched by Changes in Its Anatomy

You can't predict how a Yucca gloriosa will react to drought from its anatomy alone.

New grapevine model better predicts whole-canopy gas exchange

Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.
