Prediction scenarios of past, present, and future environmental suitability for...
Almeida, Alice; Martins, M. João; Campagnolo, Manuel Lameiras; Fernandez, Paulo; Albuquerque, M.T.D.; Gerassis, Saki; Gonçalves, José CarlosClimate change is a challenge for forests in the coming decades, with a major impact on species adaptation and distribution. The Mediterranean Basin is one of the most vulnerable hotspots for biodiversity conservation under climate change in the world. This research aimed at studying a Mediterranean species well adapted to the region: the Arbutus unedo L. (strawberry tree). The MaxEnt, a presence-only species-d...

Analog Computers and the Iteration Functional
Campagnolo, Manuel Lameiras; Moore, Cristopher; Costa, José FélixIn this paper we extend the class of differentially algebraic functions computed by Shannon's General Purpose Analog Computer (GPAC). We relax Pour-El's definition of GPAC to obtain new operators and we use recursion theory on the reals to define a new class of analog computable functions. We show that a function F(t,x) which simulates t time-steps of a Turing machine on input x, and more generally a functional...
