I've received another little present from my group to celebrate the start of my maternity leave. Let it sink in. It's brilliant!!! 🤣

(This is especially true for #AcademicParents interested in #AdaptiveDynamics. Yes, I do realise that the target group is probably quite small, but this is so damn funny that I had to post it anyways. I recommend to read "The hitchhiker's guide to adaptive dynamics" in case you want to enjoy an excellent ecoevo/maths paper - see https://core.ac.uk/download/pdf/33901766.pdf)

Eco-evolutionary dynamics in two-species mutualistic systems: one-sided population decline triggers joint interaction disinvestment - Evolutionary Ecology

The interplay between ecological and evolutionary dynamics can create feedback that reinforces external disturbances and potentially threatens species’ coexistence. For example, plants might invest less into attracting insect pollinators (decreased flower or nectar production) and more into independence (increased selfing or vegetative reproduction) when faced with pollinator decline. This adaptive response saves plant resources at the cost of further threatening the pollinator population. We ask under which conditions such self-reinforcing feedback occurs in two-species mutualistic systems when considering one-sided population decline and whether it can be counteracted by self-dampening feedback if co-evolution of both interaction partners is considered. Based on a mathematical model and in line with previous studies, we find that the described pattern of accelerated population decline occurs for a wide range of parameter values if a concave allocation trade-off between independent growth and interaction investment is assumed. The undisturbed population typically disinvests first, which then forces the declining population to also disinvest, in favour of other energy sources. However, a decelerated population decline can occur if the adaptation of the undisturbed partner is relatively slow compared to environmental decay, reducing the speed of its disinvestment, or if the initial investment into the interaction was very high. Our results suggest that if actions are taken to save endangered populations, not only the evolution of the target species but also of their interaction partner, as well as the interaction between them should be considered.

Can #metabolic acquisitions ever become permanent? Here, Alexandra Brown, Grace Casarez, and @mixotrophe apply #adaptiveDynamics to a model of "#chloroplastStealing" #microbes to find out when borrowed machinery is better than having your own.

...and another #seminar invitation: Avril Weinbach (postdoc in my team) will present her latest research on Tuesday, March 28, at 11 am:
“Eco-evolutionary responses of mutualistic systems to insect decline and changes in flowering phenology”.

This is a hybrid seminar, so please get in touch in case you would like to join and learn more about the methods that we use to study all sorts of #ecoevo dynamics!

Paper submitted! 🥳

This one is a major win because 3/4 of us are #AcademicMums. We fight with sleep deprivation, inconsistent childcare, countless illnesses and short-term contracts, so 1st author Franz Weyerer had to juggle our numerous work constraints on top of a challenging research project. But we made it work!

Here is our new #preprint showing how #coevolution of #mutualists accelerates or decelerates #pollinator extinction.

How development affects evolution

Abstract. Natural selection acts on developmentally constructed phenotypes, but how does development affect evolution? This question prompts a simultaneous cons

@ngons @JacobPhD my involvement came through biological #EvolutionaryDynamics (now #AdaptiveDynamics) before sufficient #MolecularEvolutionary evidence was available and before knowledge of #MachineLearning (when was term invented? I knew about #NeuralNetworks but didn't have computational resources to use them). #Fitness was assumed to be positive based on history of analytical models.

#introduction I am an evolutionary biologist interested by the origins of life and evolutionary transitions in individuality #ETI. I do #theory inspired by #ExperimentalEvolution.

I'd like to understand how living systems emerge and change scale.

I enjoy various approaches such as #Math #Models (#StochasticProcess, #DynamicalSystems, and #AdaptiveDynamics in particular), #PhilosophyOfScience, #Bioinformatics and #Dataviz.

I am a #FOSS and #OpenScience enthusiast. Nice to meet you all !

#AdaptiveDynamics studying #Evolution in the context of #PopulationDynamics. When I worked on it I called it #EvolutionaryDynamics but adaptive dynamics is the name that has stuck. Diagram shows the adaptive dynamics of coevolving predator and prey where no stable #EvolutionaryStableStrategy can be reached.
