Extinction of species, and even clades, is a normal part of the macroevolutionary process.
However, several times in Earth history the rate of species and clade extinctions increased …

Global warming, habitat loss and overexploitation of limited resources are leading to
alarming biodiversity declines. Ecosystems are complex adaptive systems that display …

Viruses have established relationships with almost every other living organism on Earth and
at all levels of biological organization: from other viruses up to entire ecosystems. In most …

The coexistence of obligate mutualists is often precariously close to tipping points where
small environmental changes can drive catastrophic shifts in species composition. For …

Semiarid ecosystems are threatened by global warming due to longer dehydration times
and increasing soil degradation. Mounting evidence indicates that, given the current trends …

Slowing down occurs in dynamical systems close to bifurcations or phase transitions. The
time length (τ) of ghost transients close to a saddle-node bifurcation in deterministic systems …

Complex systems such as ecosystems, electronic circuits, lasers, or chemical reactions can
be modelled by dynamical systems which typically experience bifurcations. It is known that …

Estimates of demographic parameters for lesser snow geese Anser caerulescens
caerulescens have become critical to understand ecosystem change in northern Canada …

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 …

Preserving and restoring biodiversity is becoming a great challenge as we face a world
where planetary boundaries will likely be crossed over the following decades. Such …
