Movement is important to all organisms, and accordingly it is addressed in a huge number
of papers in the literature. Of nearly 26,000 papers referring to movement, an estimated 34% …

… The parameter r X represents the … r S = 0.5 (ie, each individual has, on average, half of the
contacts in the place of work or study) and that r E = r P = r A = r R = r S , while r I = r Q = r H = 0 …

… If we interpret x as the investment in predator defense, x is constrained to be positive, and
we define the metabolic cost as r(x) = r⋅x, r being a constant. The benefit of this investment is a …

Of the 70 cases of classical biological control for the protection of nature found in our review,
there were fewer projects against insect targets (21) than against invasive plants (49), in part…

Spatiotemporal ecological modelling of terrestrial ecosystems relies on climatological and
biophysical Earth observations. Due to their increasing availability, global coverage, frequent …

Although, in nature, seed dispersal usually declines with distance from the source, seedling
establishment patterns are highly variable. An increase in seed survival can lead to either …

… We also assume that p R (τ) follows a gamma distribution of mean 14 and coefficient of
variation 0.5, which has a median of 13.7 days (0.05–0.95 quantiles: 4.78–27.14 days), in …

This paper shows that it is difficult, if not impossible, to formulate policies that guarantee that
tourism can be maintained for a long time without severely impacting on the environment. …

We develop a simple ordinary differential equation model to study the epidemiological
consequences of the drift mechanism for influenza A viruses. Improving over the classical SIR …

… (R 0 , r and T) are found to be highly variable in space. In particular, the basic reproductive
number R … nodes where R 0 > 1) and about 90 per cent of the network nodes characterized by …
