In order to better understand the relationships among current Nostocales cyanobacterial blooms, eight genomes were sequenced from cultured isolates or from environmental metagenomes of recent planktonic Nostocales blooms. Phylogenomic analysis of publicly available sequences placed the new genomes among a group of 15 genomes from four continents in a distinct...
The Rock Creek area consists of 53 square miles located in
the eastern foothills of the Pioneer Mountains, Beaverhead County,
Montana. Approximately 8, 500 feet of late Paleozoic and early
Mesozoic contact-metamorphosed sedimentary rocks and late Mesozoic
sedimentary rocks are exposed in the area of study.
Most of the late...

The Kenyan-Tanzanian coastal region in the western Indian Ocean faces several environmental challenges including coral reef conservation, fisheries management, coastal erosion, and nearshore pollution. The region lacks hydrodynamic records and oceanographic studies at adequate spatial and temporal scales to provide information relevant to the local environmental issues. We have developed...

CodY is known to regulate various virulence properties in several Gram-positive bacteria but has not yet been studied
in the important histotoxic and intestinal pathogen Clostridium perfringens. The present study prepared an isogenic codY-null
mutant in C. perfringens type D strain CN3718 by insertional mutagenesis using the Targetron system. Western...

Volunteers are increasingly being recruited into citizen science projects to collect observations for scientific studies. An additional goal of these projects is to engage and educate these volunteers. Thus, there are few barriers to participation resulting in volunteer observers with varying ability to complete the project’s tasks. To improve the...
La presente tesis provee una crítica al Programa de Educación para la Sexualidad y Construcción de Ciudadanía en Colombia y examina contribuciones teóricas de pedagogías feministas, Queer y pedagogías críticas con el fin de crear alternativas para la práctica de una educación sexual fundamentada en la justicia social. El desarrollo...

As decomposers, fungi are key players in recycling plant material in global carbon cycles. We hypothesized that genomes of early diverging fungi may have inherited pectinases from an ancestral species that had been able to extract nutrients from pectin-containing land plants and their algal allies (Streptophytes). We aimed to infer,...

Background:
Myxozoans are metazoan parasites whose traditional spore morphology-based taxonomy conflicts DNA based phylogenies. Freshwater species of the genus Hoferellus are parasites of the excretory system, with several members infecting food and ornamental fish species, as well as amphibians. This study aims to increase our understanding of their molecular diversity...
The Cedar Creek area, consisting of about 30 square miles, is
located on the west flank of the central Madison Range in Madison
County, Montana.
The rocks of the area include carbonates, sandstones, mudstones,
cherts, phosphorite, metamorphic rocks, intrusive igneous
rocks, and unconsolidated sediments and have been divided into 16...
