Pattern formation–a missing link in the study of ecosystem response to environmental changes

E Meron - Mathematical biosciences, 2016 - Elsevier
Environmental changes can affect the functioning of an ecosystem directly, through the
response of individual life forms, or indirectly, through interspecific interactions and …
