As a result of our mechanistic studies on porphyrin synthesis, 2 we have developed a modified
synthesis which represents an improvement over previous litera-ture methods3-11 for …

This study analyzed 76 species of Carnivora using a concatenated sequence of 6243 bp
from six genes (nuclear TR-iI, TBG, and IRBP; mitochondrial ND2, CYTB, and 12S rRNA), …

Environmental DNA (eDNA) is increasingly being used in aquatic environments for monitoring
species, particularly those that are of conservation concern and/or are difficult to visually …

A recent molecular phylogeny of the mammalian order Carnivora implied large body size as
the ancestral condition for the caniform subclade Arctoidea using the distribution of species …

Acanthodians, an exclusively Palaeozoic group of fish, are central to a renewed debate on
the origin of modern gnathostomes: jawed vertebrates comprising Chondrichthyes (sharks, …

Increased encephalization, or larger brain volume relative to body mass, is a repeated theme
in vertebrate evolution. Here we present an extensive sampling of relative brain sizes in …

We present a systematic study of abundance, isotopic composition and petrographic
associations of graphite in rocks from the ca. 3.8Ga Isua Supracrustal Belt (ISB) in southern West …

One expected response to observed global warming is an upslope shift of species elevational
ranges. Here, we document changes in the elevational distributions of the small mammals …

The olfactory receptor (OR) gene families, which govern mammalian olfaction, have
undergone extensive expansion and contraction through duplication and pseudogenization. …

Although relationships among the major groups of living gnathostomes are well established,
the relatedness of early jawed vertebrates to modern clades is intensely debated. Here, we …
