Dynamics of interacting generalized tipping elements on complex networks

In recent years, an increasing number of potential tipping elements
have been identified in ecological, climatic and social systems. Tipping
elements are defined by their ability to undergo large qualitative change
that is caused by a small perturbation in a parameter or state variable.
We investigate the emergent nonlinear dynamics of pairs, chains
and networks of generalized tipping elements and identify conditions under which domino effects and tipping cascades can occur. Understanding the dynamics

How far does a shock event spreads on a network? Detecting causality on the salmon trade network

Stochastic events can affect the ability of a country to produce and export natural resources such as food. When exposed to such events, an importer country will face a deficit on the expected trade of a product and turn to another training partners to supply its demand. This simple mechanism can therefore couple oscillations on resource exploitation and consumption in far away places of the planet, a phenomenon theorized as telecouplings1.

Collaborative hierarchy maintains cooperation in asymmetric games

The interplay of social structure and cooperative behavior is under much scrutiny lately as behavior in social contexts becomes increasingly relevant for everyday life. Earlier experimental work showed that the existence of a social hierarchy, earned through competition, was detrimental for the evolution of cooperative behaviors. Here, we study the case in which individuals are ranked in a hierarchical structure based on their performance in a collective e ort by having them play a Public Goods Game.

Adaptive metabolic strategies explain diauxic shifts and promote species coexistence

One of the most important open problems in ecosystem modeling is explaining the origin of biodiversity in competitive ecosystems: these are most commonly described mathematically using MacArthur's consumer-resource model, leading to the ‘‘competitive exclusion principle’’ which limits the number of coexisting competing species to the number of available resources. Nevertheless, several empirical evidences - like the ‘‘paradox of the plankton’’, but also bacterial community culture experiments - show that this principle is violated in real ecosystems.

Multiscale renewable resource management by social pressure in social-ecological systems

Social-ecological systems (SES) are complex and adaptive, with processes spanning a vast range of scales, from behaviours of individuals to global economic and earth-systems processes. Addressing urgent sustainability challenges requires an understanding of cross-scale interactions in SES; how large-scale phenomena emerge from, and feedback onto, small-scale phenomena. In this work, we model renewable resource harvesting in a multiscale, hierarchical SES in which resource stock dynamics are coupled to social dynamics constrained by a social norm of non-excessive harvesting.

Talent vs Luck: the Role of Randomness in Success and Failure

The largely dominant meritocratic paradigm of highly competitive Western cultures is rooted on the belief that success is due mainly, if not exclusively, to personal qualities such as talent, intelligence, skills, smartness, efforts, willfulness, hard work or risk taking. Sometimes, we are willing to admit that a certain degree of luck could also play a role in achieving significant material success. But, as a matter of fact, it is rather common to underestimate the importance of external forces in individual successful stories.

Human Beings and Planet Earth in Deep Time: New Challenges for Modelling The Long-Term Evolution of the Global Human-Earth System

Conventional theories of the long-term trajectory of human beings on planet earth hold that over most of our species’ existence small numbers of people had a limited influence on the earth system. The trajectory of human societies, while bounded by fluctuating climate conditions, generally rose upward in complexity as populations grew slowly. In this view, substantial influence of environmental change on people and vice-versa occurred late in the sequence and became significant only after the Industrial Revolution.

Study of Primates Social Dynamics from Temporal Co-presence data

Non-human primates have complex and flexible social relationships that can rapidly change through time. However, the study of their social network is mostly based on data coming from direct observational measures and limited to static networks, which provide an aggregated picture and do not describe the dynamics of the network (emergence of leaders, growth or stability of communities, etc.). The use of data coming from automated systems for social network analysis is quite recent but opens the possibility of a temporal network approach.

Effects of Microinsurance on Informal Safety Nets – A Model-Based Analysis

We study transport of electronic excitations (Frenkel excitons) along molecular aggregate addressing complex behaviour, which emerges beyond the limits of certain common model assumptions. We focus on the vibronic regime of transport, when quantum diffusion of Frenkel excitons is modulated by bath of underdamped vibrations. Harmonic approximation to electronic potential surfaces (linear coupling regime) allows for cost effective treatment of vibrational modulation of electronic transitions using cumulant approaches, so it is often used far beyond its formal validity.

Revisiting the Stability of a Plant-Pollinator Mutualistic Community With and Without Phenology

Plant and pollinator communities are paradigmatic examples of mutualistic ecosystems, characterized by the fact that both sets of agents interact mutually benefiting each other by the increase of reproductive fitness of plants and the access to nutrients of pollinators. Such ecosystems exhibit a marked temporal signature, called phenology, showing significant year-to-year variability as well as seasonal patterns of activity and flowering.
