Chrysolina herbacea, der grüne Minzeblattkäfer. Wie so viele Blattkäfer ein echtes Juwel und in der Lage, ähnlich wie Maiglöckchen giftige Cardenolide zur Verteidigung zu synthetisieren.

Chrysolina herbacea, the green mint leaf beetle. A natural jewel, as many other leaf beetles. It is capable of synthesizing cardiac glycosides for defence, similar to the lily of the valley.

Very proud of PhD student Cedric Maforimbo, who successfully defended his PhD thesis in viva today!

Cedric's research work is really interesting - he has piloted some new methods to identify #pollen loads on #bees & match with plants in the field margin. He has also carried out a tonne of fieldwork addressing some of our knowledge gaps around the role of field margins in support crop pollination in African legume systems, given us a load more information about what pollinates common bean (we REALLY need to understand the distribution of Xylocopa spp. and their habitat needs), and been a great colleague.

Pleasure to work with a brilliant supervisory team Phil Stevenson, Angela Mkindi, Steve Harte.

Well done Cedric!

Aposematism (Ecology 🏞️)

Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These adver...

Barley plants fine-tune their root microbial communities through sugary secretions
The custom community of beneficial microbes improve the plants’ growth

Different types of #barley recruit distinct communities of soil #microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.

#plantscience #biology #metabolomics #chemicalecology #STEM #earlycareerresearchers #botany #science #PhD #PostDoc Fellow researchers, how do you feel the scientific community on Mastodon compares to bigger platforms like LinkedIn or Twitter?

“…most of the focus in community ecology has been, up to now, on more obviously functional phenotypes — morphological diversity, and metabolic diversity. They’ve shown that the chemical content of plants’ tissues is more closely related to their phylogenetic history than traits in those categories.”

Excellent review by molecular ecologist Jeremy Yoder on recent paper examining chemical ecology & diversity. #ecology #ChemicalEcology

Always good to read about #ManducaSexta, although the mystery stated here isn't one in my opinion, it's just the plant's defence mechanism.

Architects of their own destruction: why do tobacco hornworm caterpillars attract their own predators?

The relationship between caterpillars and plants is incredibly complex and can give rise to fascinating mysteries. One such conundrum involves tobacco hornworm caterpillars and their interaction with the plants on which they feed, which seems, at first glance, to make no sense. Why do these caterpillars cause the plant they are feeding on to send signals which attract their natural predators? Scientists at the University of Amsterdam have now been able to provide new insights into this unusual connection. Their research was published today in Nature Communications.
