Comparative cytogenetics of spiny rats of the genus proechimys (Rodentia, Echim...
Eler, Eduardo Schmidt; Silva, Maria Nazareth Fda; Silva, Carlos E.F.; Feldberg, ElianaWe made a comparative analysis of the cytogenetics of spiny rat species of the genus Proechimys collected from several sites of the Madeira River basin (Amazonas State, Brazil) and Jari River valley (Pará State, Brazil). Individuals were assigned to three groups based on diploid and fundamental numbers: 2n=28, FN=46 (P. cuvieri and P. gr. longicaudatus); 2n=38, FN=52 (Proechimys gr. guyannensis), and 2n=40, FN=...

Karyological analysis of Proechimys cuvieri and Proechimys guyannensis (Rodenti...
Silva, Carlos Eduardo Faresin e; Eler, Eduardo Schmidt; Silva, Maria Nazareth Ferreira da; Feldberg, ElianaThe aim was to characterize the karyotype of rodents of the genus Proechimys from three localities in the central Brazilian Amazon, in the search for new markers that might shed light on our understanding of the taxonomy and evolutionary history of this taxon. Two karyotypes were found, viz., 2n = 28, FN = 46 in individuals from the NRSP (Cuieiras River) and REMAN (Manaus), and 2n = 46, FN = 50 in individuals f...

Phylogenetic classification of the world's tropical forests
Slik, J. W.Ferry; Franklin, Janet; Arroyo-Rodríguez, Víctor; Field, Richard; Aguilar, Salomón; Aguirre, Nikolay; Ahumada, Jorge A.; Aiba, ShinichiroKnowledge about the biogeographic affinities of the world's tropical forests helps to better understand regional differences in forest structure, diversity, composition, and dynamics. Such understanding will enable anticipation of region-specific responses to global environmental change. Modern phylogenies, in combination with broad coverage of species inventory data, now allow for global biogeographic analyses...
