In this work we model the dynamics of a population that evolves as a continuous time branching process with a trait structure and ecological interactions in form of mutations and competition between individuals. We generalize existing microscopic models by allowing individuals to have multiple offspring at a reproduction event. Furthermore, we allow the reproduction law to be influenced both by the trait type of the parent as well as by the mutant trait type. We look for tractable large… 
Ancestral lineages in spatial population models with local regulation
It is explained how an ancestral lineage can be interpreted as a random walk in a dynamic random environment and defined regeneration times allows to prove central limit theorems for such walks.
An evolution model with uncountably many alleles
We study a class of evolution models, where the breeding process involves an arbitrary exchangeable process, allowing for mutations to appear. The population size n is fixed, hence after breeding,


Nonlinear historical superprocess approximations for population models with past dependence
We are interested in the evolving genealogy of a birth and death process with trait structure and ecological interactions. Traits are hereditarily transmitted from a parent to its offspring unless a
From Individual Stochastic Processes to Macroscopic Models in Adaptive Evolution
In the limit of rare mutations, it is shown that a possible approximation is a jump process, justifying rigorously the so-called trait substitution sequence, and unify different points of view concerning mutation-selection evolutionary models.
The branching process with logistic growth
In order to model random density-dependence in population dynamics, we construct the random analogue of the well-known logistic process in the branching processes’ framework. This density-dependence
Measure-Valued Branching Diffusions with Singular Interactions
Abstract The usual super-Brownian motion is a measure-valued process that arises as a high density limit of a system of branching Brownian particles in which the branching mechanism is critical. In
Rigorous results for a population model with selection I: evolution of the fitness distribution
We consider a model of a population of fixed size $N$ undergoing selection. Each individual acquires beneficial mutations at rate $\mu_N$, and each beneficial mutation increases the individual's
Genetic Draft, Selective Interference, and Population Genetics of Rapid Adaptation
In this review, recent progress in characterizing and understanding evolution in rapidly adapting populations, in which random associations of mutations with genetic backgrounds of different fitness dominate over genetic drift are discussed.
Genealogies of rapidly adapting populations
It is argued that lineages trace back to a small pool of highly fit ancestors, in which almost simultaneous coalescence of more than two lineages frequently occurs, and should be considered as a null model for adapting populations.

Infinitely Divisible Random Measures and Superprocesses
The objective of these lectures is to serve as an introduction to the theory of measure-valued branching processes or super processes.This class of processes first arose from the study of continuous
