Can You Sequence Ecology? Metagenomics of Adaptive Diversification
(Public Library of Science, 2013)Few areas of science have benefited more from the expansion in sequencing capability than the study of microbial communities. Can sequence data, besides providing hypotheses of the functions the members possess, detect the ... -
Dynamics of the Microbiota in Response to Host Infection
(Public Library of Science, 2014)Longitudinal studies of the microbiota are important for discovering changes in microbial communities that affect the host. The complexity of these ecosystems requires rigorous integrated experimental and computational ... -
Early Warning Signals of Ecological Transitions: Methods for Spatial Patterns
(Public Library of Science, 2014)A number of ecosystems can exhibit abrupt shifts between alternative stable states. Because of their important ecological and economic consequences, recent research has focused on devising early warning signals for ... -
Electron Uptake by Iron-Oxidizing Phototrophic Bacteria
(Nature Publishing Group, 2014)Oxidation–reduction reactions underlie energy generation in nearly all life forms. Although most organisms use soluble oxidants and reductants, some microbes can access solid-phase materials as electron-acceptors or -donors ... -
The Elemental Composition of Demospongiae from the Red Sea, Gulf of Aqaba
(Public Library of Science, 2014)Trace elements are vital for the growth and development of all organisms. Little is known about the elemental content and trace metal biology of Red Sea demosponges. This study establishes an initial database of sponge ... -
The Encyclopedia of Life v2: Providing Global Access to Knowledge About Life on Earth
(Pensoft Publishers, 2014)Abstract The Encyclopedia of Life (EOL, http://eol.org) aims to provide unprecedented global access to a broad range of information about life on Earth. It currently contains 3.5 million distinct pages for taxa and provides ... -
Evidence for a Trade-Off Strategy in Stone Oak (Lithocarpus) Seeds between Physical and Chemical Defense Highlights Fiber as an Important Antifeedant
(Public Library of Science, 2012)Trees in the beech or oak family (Fagaceae) have a mutualistic relationship with scatter-hoarding rodents. Rodents obtain nutrients and energy by consuming seeds, while providing seed dispersal for the tree by allowing ... -
First phylogenetic analysis of Dryophthorinae (Coleoptera, Curculionidae) based on structural alignment of ribosomal DNA reveals Cenozoic diversification
(Wiley, 2021-02-09)Dryophthorinae is an economically important, ecologically distinct, and ubiquitous monophyletic group of pantropical weevils with more than 1,200 species in 153 genera. This study provides the first comprehensive phylogeny ... -
Four Centuries of Change in Northeastern United States Forests
(Public Library of Science, 2013)The northeastern United States is a predominately-forested region that, like most of the eastern U.S., has undergone a 400-year history of intense logging, land clearance for agriculture, and natural reforestation. This ... -
Gene family evolution underlies cell-type diversification in the hypothalamus of teleosts
(Springer Science and Business Media LLC, 2021-11-25)<jats:title>ABSTRACT</jats:title><jats:p>Hundreds of cell types form the vertebrate brain, but it is largely unknown how similar these cellular repertoires are between or within species, or how cell type diversity evolves. ... -
Genetic Diversity in the Interference Selection Limit
(Public Library of Science, 2014)Pervasive natural selection can strongly influence observed patterns of genetic variation, but these effects remain poorly understood when multiple selected variants segregate in nearby regions of the genome. Classical ... -
Identification of Listeria monocytogenes Determinants Required for Biofilm Formation
(Public Library of Science, 2014)Listeria monocytogenes is a Gram-positive, food-borne pathogen of humans and animals. L. monocytogenes is considered to be a potential public health risk by the U.S. Food and Drug Administration (FDA), as this bacterium ... -
Impacts of climate change and deforestation on hydropower planning in the Brazilian Amazon
(Springer Science and Business Media LLC, 2020-03-16)The Amazon Basin is Brazil’s next frontier for hydropower, but alterations to the water cycle from climate change and deforestation could affect river flows fueling electricity generation. This research investigated the ... -
Inferring Predator Behavior from Attack Rates on Prey-Replicas That Differ in Conspicuousness
(Public Library of Science, 2012)Behavioral ecologists and evolutionary biologists have long studied how predators respond to prey items novel in color and pattern. Because a predatory response is influenced by both the predator’s ability to detect the ... -
Integrated Tree-Ring-Radiocarbon High-Resolution Timeframe to Resolve Earlier Second Millennium BCE Mesopotamian Chronology
(Public Library of Science, 2016)500 years of ancient Near Eastern history from the earlier second millennium BCE, including such pivotal figures as Hammurabi of Babylon, Šamši-Adad I (who conquered Aššur) and Zimrilim of Mari, has long floated in calendar ... -
Intersex in male invasive Atlantic lionfish, Pterois spp.
(Inter-Research Science Center, 2019-01-10)Intersex in gonochoristic species is a reproductive abnormality in which an individual produces gametes of the type normally associated with the opposite sex. To investigate the prevalence of intersex in male lionfish ... -
Limited Gene Flow in the Brooding Coral Favia fragum (Esper, 1797)
(Springer Science + Business Media, 2010)Understanding population connectivity in corals is particularly important as these organisms are increasingly threatened by abiotic and biotic factors. This study examined the population genetic structure of the brooding ... -
The Methanol Dehydrogenase Gene, mxaF, as a Functional and Phylogenetic Marker for Proteobacterial Methanotrophs in Natural Environments
(Public Library of Science, 2013)The mxaF gene, coding for the large \((\alpha)\) subunit of methanol dehydrogenase, is highly conserved among distantly related methylotrophic species in the Alpha-, Beta- and Gammaproteobacteria. It is ubiquitous in ... -
Mixed asexual and sexual reproduction in the Indo-Pacific reef coral<i>Pocillopora damicornis</i>
(Wiley, 2013-08)Pocillopora damicornis is one of the best studied reef-building corals, yet it's somewhat unique reproductive strategy remains poorly understood. Genetic studies indicate that P. damicornis larvae are produced almost ...
