Large herbivores play unique ecological roles and are disproportionately imperiled by
human activity. As many wild populations dwindle towards extinction, and as interest grows in …

Food webs are a major focus and organizing theme of ecology, but the data used to assemble
them are deficient. Early debates over food-web data focused on taxonomic resolution …

A framework for the description and analysis of multilayer networks is established in statistical
physics, and calls are increasing for their adoption by community ecologists. Multilayer …

A recent article by Sartori stresses the importance for comparative politics of the construction
of basic concepts which are discriminatory and “classificatory,” enabling one to study “one …

Ecological niche differences are necessary for stable species coexistence but are often difficult
to discern. Models of dietary niche differentiation in large mammalian herbivores invoke …

Biological invasions are both a pressing environmental challenge and an opportunity to
investigate fundamental ecological processes, such as the role of top predators in regulating …

The concordance of evolutionary histories and extant species interactions provides a useful
metric for addressing questions of how the structure of ecological communities is influenced …

Trophic rewilding seeks to rehabilitate degraded ecosystems by repopulating them with large
animals, thereby re-establishing strong top-down interactions. Yet there are very few tests …

In this paper we examine the characteristics of high frequency pairs trading using a sample
of FTSE100 constituent stocks for the period January to December 2007. We show that the …

Interactions between plants and herbivores are central in most ecosystems, but their strength
is highly variable. The amount of variability within a system is thought to influence most …
