One of the crucial choices when modelling species distributions using pseudo-absences and background approaches is delineation area to fit model. We hypothesise that there a minimum around geographical centre distribution characterises well enough range environmental conditions needed by survive. Thus, fitting model within this should be optimal solution in terms both quality execution time. Mi...

LetM be a three-manifold (possibly with boundary). We will show that, for any positive integer γ, there exists an open nonempty set of metrics on M (in the C-topology on the space of metrics on M) for each of which there are compact embedded stable minimal surfaces of genus γ with arbitrarily large area. This extends a result of Colding and Minicozzi, who proved the case γ = 1.
