Aconitum offers bees more nectar to carry its toxic pollen

Male flowers of Aconitum protect their pollen by adding alkaloids. Without pollen as a reward, botanists asked how the flower compensated pollinators.

Ant pollination in Brazilian savanna

Ant–plant associations are widely diverse and distributed throughout the world, leading to complex ecological networks. Regarding ant–plant mutualism, ant pollination is a very rare...

Researching Pollen Illuminating the Invisible

For many people, pollen means nose itching and eyes watering - but it is so much more. It is the reason we have food on our plates, and flowers around us. When pollen forms abnormally or degenerates, it is unable to generate new life through the production of a seed. Many factors can affect pollen development, and this is what my research is about.

Limited seed and pollen gene dispersal in Taxus baccata

Dispersal is crucial due to its direct impact on dynamics of a species’ distribution as well as having a role in shaping adaptive potential...

Glycoprotein secretions and pollen tube kinetics in apple

The obturator bridges the downward transit of the pollen tube through style to ovary in many angiosperms. Examining pollen tube growth kinetics in the...

This item concerns uses of botanical bits-and-pieces in ways that Nature never intended. But having also brought forth Man, that natural entity has given...

Hanging On To Your Date, Avoiding Incest And Not Getting Infected – All In A Day’s Work For Flowers Of The Mustard Family

In the mustard family, which includes the important crop Brassica (rapeseed/canola) and the model plant Arabidopsis, the surfaces of the female stigmatic cells are...

Temporal variation in gender in an annual plant

The widespread tendency towards declining fruit set from first to last flowers on plants may contribute to temporal variation in allocation optima.

Cause for optimism (maybe not…)

There’s an insufficiency of people to grow the new crops that aren’t being identified because of the dearth of plant taxonomists. Where will it all end..?

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...
