Abstract:
In this paper we present a realization of Volterra processes within the white noise analysis framework. We show that Donsker's delta functions of Volterra processes are elements from the space of Hida distributions. An explicit expression for the corresponding chaos decomposition in terms of Wick tensor powers of white noise is also given.

Abstract We consider stochastic partial differential equations appearing as Markovian lifts of matrix-valued (affine) Volterra-type processes from the point of view of the generalized Feller property (see, e.g., Dörsek and Teichmann in A semigroup point of view on splitting schemes for stochastic (partial) differential equations, 2010. arXiv:1011.2651). We introduce in particular Volterra Wishart processes with fractional kernels and values in the cone of positive semidefinite matrices. They are constructed from matrix products of infinite dimensional Ornstein–Uhlenbeck processes whose state s

We consider stochastic differential equations driven by some Volterra processes. Under time reversal, these equations are transformed into past-dependent stochastic differential equations driven by a standard Brownian motion. We are then in position to derive existence and uniqueness of solutions of the Volterra driven SDE considered at the beginning.

Abstract:
This chapter first considers the question of how ecologists have conceptualized populations. In other words, how has their research looked at “group[s] of individuals of one species”? It reflects on the classical models that form the theoretical basis of population ecology: the Lotka–Volterra competition model, Lotka–Volterra predator–prey model, and Fretwell–Oksanen food chain model. It then argues that much of ecologists' understanding about populations and communities and their dynamics is couched in terms of mathematical models. The remainder of the chapter discusses individual- versus population-level assumptions, the population dynamical triad, growth patterns and ecology of ontogenetic development, body-size scaling and magnitude of body-size changes, and changes in ecological roles over ontogeny.

Abstract:
Investigation of how spatial processes affect the maintenance of biodiversity and its geographic distribution has led to landmark contributions in community ecology. Theory has followed a logical complexification of the objects of study, with specific models at each step, from populations connected by dispersal to ecosystems connected by flows of energy and material. This large body of theory is not only diverse in the questions it addresses, and the scales and organization levels it encompasses, but also in the types of models used to represent spatial dynamics. Unfortunately, this makes it hard to establish clear, standard, quantitative predictions stemming from a coherent mathematical formalism. Here our objectives are : i) to propose a general metacommunity model that allows the investigation of spatial ecology from populations to entire food webs ; ii) use the model to review a set of principles driving coexistence in all types of metacommunities; iii) reveal how these principles constrain the spatial distribution of diversity, with a particular emphasis on species co-distribution. The model is based on the well-established representation of spatial dynamics through colonization and extinction processes. We generalize Levins’ metapopulation model to all types of ecological interactions, using a formalism akin to Lotka–Volterra equations for local community dynamics. Doing so, we revisit coexistence mechanisms proposed for competitive metacommunities, along with the assembly dynamics for spatial food webs and mutualistic interactions.

The simulation results are appropriately processed and the Volterra representation of the system dynamics is formulated.
