🐬 In quiet water, a dolphin nudges a pufferfish, and the moment can look playful. What follows remains uncertain. Chemistry may matter, while play and exploration remain plausible.
The quieter question continues:

Oil beetle larvae #smell like #flowers to manipulate #bees
The European oil beetle's parasitic larvae emit a floral #scent that attracts wild bees. This allows the larvae to sneak into the bees' nests

🧫 In many habitats, animals move through invisible tides of chemistry that shape touch, play, and risk. Curious how dolphins, pufferfish, and other species meet molecules in the wild?

Daphnia (water fleas) exhibit phenotypic plasticity by altering their physical structure—such as growing enlarged heads or defensive spines—in direct response to chemical signals emitted by nearby predators.

Step-By-Step Evolution Of A Chemical Weapons System By Poison Frogs
Poison frogs appear to have built their chemical defenses gradually: related frogs store low to moderate levels of diet-derived alkaloids, whilst poison frogs store more and could chemically modify them.

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.

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.

Key concepts: species interactions (plant-microbe, plant-herbivore, plant-pollinator, herbivore-predator); chemical ecology and related methodologies (LC-MS, GC-MS, metabolomics); R-stats; fungal plant symbionts (incl. endophytic fungi, mycorrhizal fungi)
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.

It’s #introduction time! I’m Hannah, I’m leading the Lab of Colourful Animals at the Max Planck Institute for Chemical Ecology in Jena, Germany. We work together to understand the role that toxins play in driving the evolution of new adaptations in predators and prey. We research poison frogs in Costa Rica; snakes that eat toxic toads; milkweed plants, milkweed herbivores, and the predators of these herbivores.

… We’ve accidentally selected for epichloë+plants which can be problematic since the chemicals sicken livestock. An example of an alkaloid you might know—LSD is produced by this group of fungi!
Our group is #NSF funded to look at how Epichloë changes the microbiome within dune grass. Since it’s vastly changing the #ChemicalEcology we expect this to drive community composition and microbiome networks
A lot has changed since my #introduction:
Now I'm a #postdoc in Liège (Belgium) trying to figure out how #neuroethology works.
I will be working with two #Peromyscus species.
My focus is the processing of #smell, especially #predator #odours, but most likely also #SocialOdors
I'm still looking for more #AnimalBehaviour, #BehavioralEcology, and #ChemicalEcology folks to follow!
