In ecology, populations may be linked conceptually with landscapes through habitat and spatial population models. ...
Landscape pattern analysis was the first attempt to deal with multiple species, and it led to a range of landscape management strategies. ...
Landscape ecology focuses on the link between the spatial pattern of a landscape and the dynamics of the species it supports. There are many ways to explore and characterize this link. ...

Notably, the degree of robustness of these systems for transporting energy is not known considering their realistic interactions with vibrational and radiative environments within the surrounding solvent ...
We observe that the dynamics of the Fenna-Matthews-Olson (FMO) complex leads to optimal and robust energy transport due to a convergence of energy scales among all important internal and external parameters ...
The difficulty is that for studying the optimality or robustness of these complexes one has to fully explore both topology and geometry of energy transfer efficiency landscape outside of the known values ...

The result indicates that Spatial Entropy index shows a robust fractal feature, and it decreases as the spatial scale (or grain size) becomes lager in a moderate degree. ...
However, the effects of changing spatial scale on Hs has not been quantified. This paper applies the fractal method to measure the spatial scale (grain size) sensitivity of Hs. ...
A COD value close to 1 means a robust fractal feature of the metrics, this is to say, this landscape metric exhibits a power law that is highly consist and robust over a range of scales (Wu, 2004) . ...
