Data from: Network analysis by simulated annealing of taxa and islands of Macaronesia (North Atlantic Ocean)
With the aim of explaining the role that taxa and island features have in biogeographical patterns, we processed presence-absence matrices of all the Macaronesian native species of ten different taxa (arthropods, birds, bryophytes, fungi, lichens, mammals, mollusks, pteridophytes, reptiles and sperm...

With the aim of explaining the role that taxa and island features have in biogeographical patterns, we processed presence-absence matrices of all the Macaronesian native species of ten different taxa (arthropods, birds, bryophytes, fungi, lichens, mammals, mollusks, pteridophytes, reptiles and spermatophytes) through simulated annealing analysis.
