▪ Abstract Many uses of gene trees implicitly assume that nominal species are monophyletic
in their alleles at the study locus. However, in well-sampled gene trees, certain alleles in one …

▪ Abstract We examine the genetics of marine diversification along the West Coast of North
America in relation to the Late Neogene geology and climate of the region. Trophically …

" Rather than favoring only one approach, Juan J. Morrone proposes a comprehensive
treatment of the developments and theories of evolutionary biogeography. Evolutionary …

The deer mouse (genus Peromyscus) is the most abundant mammal in North America, and it
occupies almost every type of terrestrial habitat. It is not surprising therefore that the natural …

Teniendo en cuenta los avances metodológicos habidos en los últimos ocho años, se
propone la actualización a nivel subespecífico del listado, incluyendo los cambios …

In this paper, we develop a five-step approach for analysis of historical relationships among
areas of endemism using a set of 22 clades (9 mammal, 7 bird, 4 reptile, 1 amphibian, and 1 …

Two new compounds, an ent-isopimarane-type diterpene, 3α, 12α-dihydroxy-ent-8 (14), 15-
isopimaradien-18-al (1), and a dihydrobenzo [b] furan neolignan,(−)-trans-9-acetyl-4, 9 '-di-O …

Population disjunctions, as a first step toward complete allopatry, present an interesting
situation to study incipient speciation. The geological formation of the Baja California …

Summary 1 We have assessed how different host parameters affect species richness of flea
assemblages using the independent contrasts method. Three groups of host parameters …

Distinguishing the historical effects of gene migration and vicariance on contemporary
genetic structure is problematic without testable biogeographic hypotheses based on …
