Spatial patterns in ecological systems: from microbial colonies to landscapes

R Martinez-Garcia, CE Tarnita… - Emerging topics in life …, 2022‏ - portlandpress.com
Self-organized spatial patterns are ubiquitous in ecological systems and allow populations
to adopt non-trivial spatial distributions starting from disordered configurations. These …

A mechanistic framework for complex microbe-host symbioses

G Araujo, JM Montoya, T Thomas, NS Webster… - Trends in …, 2024‏ - cell.com
Virtually all multicellular organisms on Earth live in symbiotic associations with complex
microbial communities: the microbiome. This ancient relationship is of fundamental …

Integrating theory and experiments to link local mechanisms and ecosystem-level consequences of vegetation patterns in drylands

R Martinez-Garcia, C Cabal, JM Calabrese… - Chaos, Solitons & …, 2023‏ - Elsevier
Self-organized spatial patterns of vegetation are frequent in drylands and, because pattern
shape correlates with water availability, they have been suggested as important indicators of …

Demographic effects of aggregation in the presence of a component Allee effect

DCP Jorge, R Martinez-Garcia - Journal of the Royal …, 2024‏ - royalsocietypublishing.org
The component Allee effect (AE) is the positive correlation between an organism's fitness
component and population density. Depending on the population spatial structure, which …

Non-local interaction effects in models of interacting populations

MI Simoy, MN Kuperman - Chaos, Solitons & Fractals, 2023‏ - Elsevier
We consider a couple of models for the dynamics of the populations of two interacting
species, inspired by Lotka–Volterra's classical equations. The main feature of this work is …

Pulsed interaction signals as a route to biological pattern formation

EH Colombo, C López, E Hernández-García - Physical Review Letters, 2023‏ - APS
We identify a mechanism for biological spatial pattern formation arising when the signals
that mediate interactions between individuals in a population have pulsed character. Our …

Interpreting how nonlinear diffusion affects the fate of bistable populations using a discrete modelling framework

Y Li, PR Buenzli, MJ Simpson - Proceedings of the …, 2022‏ - royalsocietypublishing.org
Understanding whether a population will survive or become extinct is a central question in
population biology. One way of exploring this question is to study population dynamics using …

Interplay between scales in the nonlocal FKPP equation

GG Piva, EH Colombo, C Anteneodo - Chaos, Solitons & Fractals, 2021‏ - Elsevier
We consider a generalization of the FKPP equation for the evolution of the spatial density of
a single-species population where all the terms are nonlocal. That is, the spatial extension of …

Nonlocal models in biology and life sciences: sources, developments, and applications

S Pal, R Melnik - arxiv preprint arxiv:2401.14651, 2024‏ - arxiv.org
Nonlocality is important in realistic mathematical models of physical and biological systems
at small-length scales. It characterizes the properties of two individuals located in different …

Linking intrinsic scales of ecological processes to characteristic scales of biodiversity and functioning patterns

YR Zelnik, M Barbier, DW Shanafelt, M Loreau… - Oikos, 2024‏ - Wiley Online Library
Ecology is a science of scale, which guides our description of both ecological processes and
patterns, but we lack a systematic understanding of how process scale and pattern scale are …
