Abstract Zebrafish have become an important model animal for studying the emergence of collective behavior in nature. Here, we show how to properly analyze the polarization statistics to distinguish shoal regimes. In analogy with the statistical prop

We a propose an adaptive population model, which is structured in groups, to investigate the appearance of division of labor. In the model, the individuals respond to a given set of stimuli according to their propensities for producing the action. In

The effects of habitat fragmentation and their implications for biodiversity is a central issue in conservation biology which still lacks an overall comprehension. There is not yet a clear consensus on how to quantify fragmentation even though it is

Tradeoffs are supposed to play a key role in driving the maintenance and the generation of biodiversity. Although an extensive literature exists on the effect of single tradeoffs, the interplay of simultaneous tradeoffs is not well studied, especiall

We use the tools of the random matrix theory (RMT) to investigate the statistical behavior of the evolution of human immunodeficiency virus (HIV) infection. By means of the nearest-neighbor spacing distribution we have identified four distinct regime

The natural ecosystems provide services that are crucial for our survival as climate control, food and water security. A very persistent pattern is loss of biodiversity caused by human activities all over the world, mainly due to deforestation and ag

We study how the mode of dynamic habitat loss and fragmentation can impact the levels of biodiversity in an ecosystem. The problem is formulated into the framework of resource-based modelling and, opposed to previous studies relying on neutral models

Dispersal is a key mechanism shaping observed ecological and evolutionary processes. Owing to its inherent costs, dispersal incur trade-offs with many life-history traits. Here we propose and investigate a metapopulation model that follows an extinct

Habitat fragmentation displays a crucial role in conservation biology. Despite this, little is known about the detailed ecological consequences of habitat fragmentation due to the scarce number of controlled experimental surveys. The species–area r
