Current ecosystems are suffering from the Anthropogenic threats that are risking our own existence. The effects of human societies are pushing the biomes to cross their own limits, even reaching their tipping points. For instance, the rise of global temperature is increasing the aridity in already arid, and thus promoting changes in for instance th...
Article
Full-text available
Transients in ecology are extremely important since they determine how equilibria are approached. The debate on the dynamic stability of ecosystems has been largely focused on equilibrium states. However, since ecosystems are constantly changing due to climate conditions or to perturbations driven by the climate crisis or anthropogenic actions (hab...

Cognitive networks have evolved to cope with uncertain environments in order to make reliable decisions. Such decision making circuits need to respond to the external world in efficient and flexible ways, and one potentially general mechanism of achieving this is grounded in critical states. Mounting evidence has shown that brains operate close to...

Article
With ongoing climate change, the probability of crossing environmental thresholds promoting abrupt changes in ecosystem structure and functioning is higher than ever. In drylands (areas where it rains less than 65% of what could be potentially evaporated), recent research has shown how the crossing of three aridity thresholds (at aridity [1‐Aridity...
Article
Critical slowing down arises close to bifurcations and involves long transients. Despite slowing down phenomena have been widely studied in local bifurcations i.e., bifurcations of equilibrium points, less is known about transient delay phenomena close to global bifurcations. In this paper, we identify a novel mechanism of slowing down arising in t...

Full-text available
Complex dynamical fluctuations, from intracellular noise, brain dynamics or computer traffic display bursting dynamics consistent with a critical state between order and disorder. Living close to the critical point has adaptive advantages and it has been conjectured that evolution could select these critical states. Is this the case of living cells...

With ongoing climate change, the probability of crossing environmental thresholds promoting abrupt changes in ecosystem structure and functioning is higher than ever. In drylands (sites where it rains less than 60% of what is evaporated), recent research has shown how the crossing of three particular aridity thresholds (defining three consecutive p...

Multicellular entities are characterized by intricate spatial patterns, intimately related to the functions they perform. These patterns are often created from isotropic embryonic structures, without external information cues guiding the symmetry breaking process. Mature biological structures also display characteristic scales with repeating distri...

Semiarid ecosystems are threatened by global warming due to longer dehydration times and increasing soil degradation. Mounting evidence indicates that, given the current trends, drylands are likely to expand and possibly experience catastrophic shifts from vegetated to desert states. Here, we explore a recent suggestion based on the concept of ecos...

Multicellular entities are characterized by exquisite spatial patterns, intimately related to the functions they perform. Oftentimes these patterns emerge as periodic structures with a well-defined characteristic scale. A candidate mechanism to explain their origins was early introduced by Alan Turing through the interaction and diffusion of two so...

Article
Discrete-time dynamics, mainly arising in boreal and temperate ecosystems for species with non-overlapping generations, have been largely studied to understand the dynamical outcomes due to changes in relevant ecological parameters. The local and global dynamical behaviour of many of these models is difficult to investigate analytically in the para...
Article
Full-text available
The long-term coevolution of hosts and pathogens in their environment forms a complex web of multi-scale interactions. Understanding how environmental heterogeneity affects the structure of host–pathogen networks is a prerequisite for predicting disease dynamics and emergence. Although nestedness is common in ecological networks, and theory suggest...

What is the potential for synthetic biology as a way of engineering, on a large scale, complex ecosystems? Can it be used to change endangered ecological communities and rescue them to prevent their collapse? What are the best strategies for such ecological engineering paths to succeed? Is it possible to create stable, diverse synthetic ecosystems...

A multitude of physical, chemical, or biological systems evolving in discrete time can be modelled and studied using difference equations (or iterative maps). Here we discuss local and global dynamics for a predator-prey two-dimensional map. The system displays an enormous richness of dynamics including extinctions, co-extinctions, and both ordered...

Ecological systems are complex dynamical systems. Modelling efforts on ecosystems' dynamical stability have revealed that population dynamics, being highly nonlinear, can be governed by complex fluctuations. Indeed, experimental and field research has provided mounting evidence of chaos in species' abundances, especially for discrete-time systems....
Poster
Full-text available
Climate change is pushing ecosystems towards extreme conditions and possibly towards tipping points. In drylands, this means to shift from vegetated to desert landscapes. In this poster, we present two approaches to stop the advances of the deserts across the nowadays vegetated semiarid ecosystems. First, replanting vegetation from time to time. Se...

Full-text available
Semiarid ecosystems are intrinsically bistable. They are systems that can be vegetated or desert under the same climatic conditions. Nowadays, in the global warming conditions, they are pushed towards the tipping points. From dynamical systems, it is known that there is the so-called ghost phenomenon just after the tipping point. In this poster, we...
Article
Semiarid ecosystems (including arid, semiarid and dry-subhumid ecosystems) span more than 40% of extant habitats and contain a similar percentage of the human population. Theoretical models and palaeoclimatic data predict a grim future, with rapid shifts towards a desert state, with accelerated diversity losses and ecological collapses. These shift...

Multicellularity is a crucial innovation that has taken place independently at least 25 times in the evolution of life on our planet. Uncovering the evolutionary rules associated to the emergence of this transition has been partially achieved thanks to a combination of comparative cell biology,phylogenetic, paleobiology and genomic studies of primi...

Semiarid ecosystems (including arid, semiarid and dry-subhumid ecosystems) span more than 40% of extant habitats and a similar percentage of human population. As a consequence of global warming, these habitats face future potential shifts towards the desert state characterized by an accelerated loss of diversity and stability leading to collapse. S...

Although the presence of vast amounts of plastic in the open ocean has generated great concern due to its potential ecological consequences, recent studies reveal that its measured abundance is much smaller than expected. Regional and global studies indicate that the difference between expected and actual estimates is enormous, suggesting that a la...
Article
Full-text available
Associative learning is one of the key mechanisms displayed by living organisms in order to adapt to their changing environments. It was early recognized to be a general trait of complex multicellular organisms but also found in "simpler" ones. It has also been explored within synthetic biology using molecular circuits that are directly inspired in...

Ecosystems are complex systems, currently experiencing several threats associated with global warming, intensive exploitation, and human-driven habitat degradation. Such threats are pushing ecosystems to the brink of collapse. Because of a general presence of multiple stable states, including states involving population extinction, and due to intri...

The aim of this project is to explore the existence of delayed transitions - states that will not last even without changes in the environmental conditions - in ecological systems. They are especially relevant in the current planetary state where anthropogenic interventions are pushing ecosystems towards their tipping points. To do this exploration, we use mathematical models (such as differential equations, stochastic simulations, and cellular automatas) that take into account the key ecological roles (i.e. producers, consumers, predators, parasites, and cooperators) and the human interventions (i.e. deforestation, hunting, or polution) to map the possible transitions that may occur and their transient behavior.
