Equilibrium States of Two Stochastic Models in Mathematical Ecology [PDF]
arXiv, 2007 This work deals with two problems arising in mathematical ecology. The first problem is concerned with diploid branching particle models and its behavior when rapid stirring is added to the interaction. The particle models involve two types of particles, male and female, and branching can only occur when both types of particles are present.

Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters
Frontiers in Microbiology, 2018 Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

Modeling of small sea floaters in the central Mediterranean Sea: seasonality of at-sea distributions [PDF]
arXiv, 2018 Floating marine debris represent a threat to marine and coastal ecology. Since the Mediterranean basin is one of the highly impacted regions, both by the coastal pollution as well as from sea traffic, the potential harm of a floating pollution on the marine ecology could be overwhelming in this area.

Discreteness of populations enervates biodiversity in evolution [PDF]
arXiv, 2010 Biodiversity widely observed in ecological systems is attributed to the dynamical balance among the competing species. The time-varying populations of the interacting species are often captured rather well by a set of deterministic replicator equations in the evolutionary game theory.

Generalized Stoichiometry and Biogeochemistry for Astrobiological Applications [PDF]
arXiv, 2020 A central need in the field of astrobiology is generalized perspectives on life that make it possible to differentiate abiotic and biotic chemical systems. A key component of many past and future astrobiological measurements is the elemental ratio of various samples.

Nonequilibrium Statistical Physics in Ecology: Vegetation Patterns, Animal Mobility and Temporal Fluctuations [PDF]
arXiv, 2017 This thesis focuses on the applications of mathematical tools and concepts brought from nonequilibrium statistical physics to the modeling of ecological problems. The first part provides a short introduction where the theoretical concepts and mathematical tools that are going to be used in subsequent chapters are presented.
