The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted
the attention of naturalists for centuries. Despite major advances in recent years in our …

The origins of interactions between angiosperms and fruit‐eating seed dispersers have
attracted much attention following a seminal paper on this topic by T iffney (1984). This …

Species richness varies widely across extant clades, but the causes of this variation remain
poorly understood. We investigate the role of diversification rate heterogeneity in shaping …

The mechanisms underlying the high extant biodiversity in the Neotropics have been
controversial since the 19th century. Support for the influence of period-specific changes on …

The Yellow-shouldered bats, Genus Sturnira, are widespread, diverse, and abundant
throughout the Neotropical Region, but little is known of their phylogeny and biogeography …

A central issue in ecology is the definition and identification of keystone species, ie species
that are relatively more important than others for maintaining community structure and …

Diet is commonly assumed to affect the evolution of species, but few studies have directly
tested its effect at macroevolutionary scales. Here we use Bayesian models of trait …

Human-modified landscapes are composed of different types of land covers in differing
proportions (landscape composition), and each with differing spatial physiognomy …

Dietary adaptation is a major feature of phenotypic and ecological diversification, yet the
genetic basis of dietary shifts is poorly understood. Among mammals, Neotropical leaf …

Morphological characters are indispensable in phylogenetic analyses for understanding the
pattern, process, and tempo of evolution. If characters are independent and free of …
