Aim To illustrate the use of natural historical data to evaluate vicariance and dispersal as hypotheses competing to explain disjunct populations. Location Nine disjunct areas on the margin of the Tyrrhenian basin of the Mediterranean Sea. Methods Fi

During the last several centuries, the high granite mesas in eastern Portugal south of the Douro river have been a major rye growing region. About half the rye produced was carried away to feed urban populations. The loss from the village agro-ecosys

Two characters are stratigraphically compatible if some phylogenies indicate that their combinations (state-pairs) evolved without homoplasy and in an order consistent with the fossil record. Simulations assuming independent character change indicate

Giesta (Cytisus) is the dominant or only woody plant on about one-quarter of the land area of the high granite mesas of interior Beira Alta, Portugal, where for at least the past 800 years the main cereal crop has been rye. During this time, a substa

Phylogenetic relationships among the four major lineages of land plants (liverworts, mosses, hornworts, and vascular plants) remain vigorously contested; their resolution is essential to our understanding of the origin and early evolution of land pla

Archaeologists seek to analyze patterns of similarity and difference among diverse kinds of assemblages that (1) vary in the number of specimens and (2) have been characterized by standard multi-category frequency distributions. Recent developments i

We test the hypothesis that the choice by traditional people of species of plants for medicinal use does or does not depend on the families to which those species belong. Our geographic context is continental North America north of the Rio Grande Riv

The amount of data with which a historian works is sometimes limited by the availability of sources. When qualitative distinctions are to be compared in the context of only a small amount of data, ACTUS, a computer application originally described in
