Living sloths represent two distinct lineages of small-sized mammals that independently
evolved arboreality from terrestrial ancestors. The six extant species are the survivors of an …

The living tree sloths Choloepus and Bradypus are the only remaining members of Folivora,
a major xenarthran radiation that occupied a wide range of habitats in many parts of the …

The analysis of stable isotopes on fossil mammals has become a widely used tool for
understanding the paleoecology and paleodiet of these organisms. In this work, we study …

We present a taxonomic revision of maned sloths, subgenus Bradypus (Scaeopus), a taxon
endemic to the Brazilian Atlantic Forest and currently composed of a single species, the …

The charismatic trumpetfishes, goatfishes, dragonets, flying gurnards, seahorses, and
pipefishes encompass a recently defined yet extraordinarily diverse clade of percomorph …

The timing of the placental mammal radiation has been the focus of debate over the efficacy
of competing methods for establishing evolutionary timescales. Molecular clock analyses …

Phylogenetic relationships among sloths (Folivora) have been extensively studied in the
past few decades using maximum parsimony approaches. Recently, Bayesian phylogenetic …

Megamammals constituted an important component in the Pleistocene faunal communities
of South America. Paleobiological and paleoecological studies involving different …

Abstract Long-horned bees (Apidae, Eucerini) are found in different biomes worldwide and
include some important crop pollinators. In the Western Hemisphere, Eucerini received …

The phylogeny of mylodontid sloths has recently been the subject of multiple studies.
Contrasting hypotheses have been proposed, especially for the relationships among late …
