What Determines Food Web Structure?
In nature species interact among each other in many ways. The most common and studied interaction is that between a predator and its prey. A food web can be defined as a network of interactions that describes who eats whom in a certain ecosystem and at a certain time of the year.

What Determines Food Web Structure?
Stochastic Network Interaction Model (SNIM) Tutorial
This is a beautifully simple ecological network model that can simulate predator-prey and competitive multispecies dynamics. This is the B model of the paper 1, I read it long ago and for many years I wanted to make a version of it, finally, I did it.

Stochastic Network Interaction Model
SNIM This is a C++11 implementation of a stochastic multispecies model. The model has multiple applications to investigate the relationship between ecological interactions (competition, predation) and diversity. It involves a discrete definition of individuals belonging to a given set of species.

PICT 2020 - Estudio de los bosques a nivel global: cambios de estado y alertas tempranas
Resumen Uno de los cambios más importantes producidos por el hombre en el planeta es el reemplazo de las áreas de bosque con paisajes dominados por las actividades humanas. Este reemplazo produce la deforestación y constituye una de las principales causas de extinciones en el antropoceno.

Redes de interacciones Ecologicas, la influencia del cambio global y la degradación del hábitat
La explotación y la degradación de los hábitats naturales junto con el cambio climático producen la pérdida de especies y de servicios ecosistémicos. La manera en que las especies forman redes de interacciones determina su estabilidad y resistencia ante los disturbios. En este proyecto, proponemos estudiar las redes de interacción ecológicas incorporando los distintos tipos de interacción (tróficas, mutualistas y competitivas), los disturbios como el cambio de temperatura y la fragmentación del hábitat, que ensamblan las redes de interacción a diferentes escalas, desde la de comunidades locales a la biogeográfica. Acoplado a esto, investigaremos la fragmentación de uno de los ambientes terrestres más importantes, los bosques, a escala global, para producir señales de alerta temprana con respecto a la pérdida de biodiversidad.
