Yet, dishonest plants persist in the population. How they are maintained despite strong bee preference for honesty remains a mystery!

🧬 Here, we show that the degree of plant honesty is partly heritable. Since bees favor honest plants, they can drive the evolution of honesty—leading to higher seed production in honest plants.

🌸 An honest plant exhibits a positive correlation between its signal and reward, allowing bees to learn this association and prefer honest plants over dishonest ones.

🐝 Bees searching for flowers cannot directly see how much nectar (i.e., reward) a flower contains. Instead, they rely on honest floral signals, such as flower size or scent.

Genetic variation in the honesty of plants to their pollinators Pollinators prefer flowers with traits that reliably indicate reward quality or quantity, a relationship defining ‘honest signals’. Despite its prevalence in plant–pollinator interactions, genetic v...

Super excited about my latest paper published in one of my favorite journals @newphyt.bsky.social

🌸🐝 Plant honesty to their pollinators is partly heritable; bees prefer honest plants and these produce more seeds.

Then why are there dishonest genotypes? 🤔 that's the next question!

The use of different colors allowed distinguishing pollen movement within and between flowers. This procedure was applied to each experimental trial to estimate the efficiency of cross-pollination and how this depends or not on the phenotype of neighboring plants.

A Continuum From Positive to Negative Interactions Drives Plant Species' Performance in a Diverse Community We explored the patterns of species performance in a real-world community, dependent on pairwise and higher-order interactions with species belonging to the same and other trophic levels (plant, herb....

Yayy 🌱🪲🐝🐌- A list of stellar ecologists and myself showed that (1) species interactions can be summarised at the guild level, except for a few critical species, (2) they occur along a continuum from positive-to-negative, and (3) they have relatively weak strength except between plants!

Congrats! I'm so looking forward to reading this paper 🤩

Van Valen's Red Queen Hypothesis says that species within ecosystems must constantly change (as in Alice in Wonderland, my drawing) to remain in place. This classic paper was rejected multiple times, and the author created a new journal to publish it mn.uio.no/cees/english...

This is a great initiative. I wonder if it has anything to do with the plant-pollinator interaction networks collected by the collective efforts of lots of people during Covid times. As far as I recall, that was coordinated by @jeffollerton.bsky.social

We show that plant reproduction can be highly plastic at different stages of the process and spatiotemporal scales, affecting plant ecology and evolution, and that in crops 🌾 such plasticity can be beneficial or detrimental.

Together with Hanneke Suijkerbuijk and Erik H. Poelman, we have compiled the existing literature and reviewed this important and timely topic.

Although we know that plants 🌿 can be highly plastic and adjust to real-time changes in their environment, there has been no discussion about how plastic are plants in their reproduction.

Plant reproduction is therefore a crucial process that provides us with food and allows plants to continue to exist and adapt to their ever-changing environment.

A fruit is a fertilized ovary 🍎, seeds like almonds are fertilized ovules (and by the way, almonds need 100% pollination by bees).

Most of the seeds, fruits and vegetables we enjoy are the result of plant reproduction 🌸 🌻 🐝.

Is there a similar effort for the evolution/evolutionary biologists community? thanks

New paper from our group! We found that maize plants from push-push fields had a higher relative abundance of metabolites toxic to insect herbivores. This suggests that maize plants growing with companion plants are "stronger" than maize plants growing alone.
