The ε-proteobacteria have recently been recognized as globally ubiquitous in modern
marine and terrestrial ecosystems, and have had a significant role in biogeochemical and
geological processes throughout Earth's history. To place this newly expanded group, which …

Phylogenetic relationships among all of the major decapod infraorders have never been
estimated using molecular data, while morphological studies produce conflicting results. In
the present study, the phylogenetic relationships among the decapod basal suborder …

Filamentous microbial mats from three aphotic sulfidic springs in Lower Kane Cave,
Wyoming, were assessed with regard to bacterial diversity, community structure, and
ecosystem function using a 16S rDNA-based phylogenetic approach combined with …

Opsin proteins are essential molecules in mediating the ability of animals to detect and use
light for diverse biological functions. Therefore, understanding the evolutionary history of
opsins is key to understanding the evolution of light detection and photoreception in …

Hydrogen sulfide-rich groundwater discharges from springs into Lower Kane Cave,
Wyoming, where microbial mats dominated by filamentous morphotypes are found. The full-
cycle rRNA approach, including 16S rRNA gene retrieval and fluorescence in situ …

Recently, researchers have begun to identify the prevalence of trait simplification, loss and
reversal across all levels of biological organization. These studies have taken increasingly
integrated approaches, incorporating phylogenetic, developmental and molecular methods …

Bat flies are a small but diverse group of highly specialized ectoparasitic, obligatory
bloodsucking Diptera. For the first time, the phylogenetic relationships of 26 species and five
subfamilies were investigated using four genes (18S rDNA, 16S rDNA, COII, and cytB) under …

Microbial mats from hydrogen sulfide-rich waters and cave-wall biofilms were investigated
from Cesspool Cave, Virginia, to determine community composition and potential
geomicrobiological functioning of acid-producing bacteria. Rates of microbial mat …

Investigations of opsin evolution outside of vertebrate systems have long been focused on
insect visual pigments, whereas other groups have received little attention. Furthermore, few
studies have explicitly investigated the selective influences across all the currently …

To investigate the relations among popular measures of neonatal stress and their link to
subsequent temperament, 50 full‐term newborns from a normal care nursery were
examined responding to a heelstick blood draw. Baseline and heelstick measures of …
