Aphids are a widespread family of plant pests, whose abilities to suppress shoot
and root growth are well documented for many terrestrial plants. Only a few studies have
been conducted on conifer aphids of the genus Cinara. Cinara pseudotsugae are known
to attack Douglas-fir seedlings, an important crop in the...
Deaf students in mainstream colleges are withdrawing at an alarming rate. Approximately 70% of the 123,000 deaf students enrolled in 2,300 colleges across the United States will not persist until graduation. This qualitative study examined what factors in the academic and social environment are linked to deaf college students' perceptions...
Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...
Motivation: It can take considerable amounts of time and effort to use existing computational tools to analyze a small RNA sequence for the purpose of determining if it is characteristic of microRNA. It is similarly tedious to search for homologs to known microRNA sequences in the rapidly growing collection of...
In developed country markets, the consideration of consumer wants has not been prominent hitherto in aquaculture production decisions. Like capture fisheries aquaculture has been product driven. This supply-side focus reflects an emphasis upon technical solutions to the production and capacity problems of high unit value (HUV) species culture. Whilst this...
As the various mechanisms of fisheries resources management have matured, fishermen increasingly have responded by devising and developing different forms of collective representation. Within the European Union (EU), Producer's organisation (POs) provide a voluntary organisational structure which has evolved since its inception in the 1970s. During the intervening period, POs...
Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity...
Discerning the intricacies of mating systems in butterflies can be difficult,
particularly when multiple mating strategies are employed and are cryptic and not
exclusive. We observed the behavior and habitat use of 113 male Taylor’s
checkerspot butterflies (Euphydryas editha taylori). We confirmed that two distinct
mating strategies were exhibited; patrolling...
For the past several decades, amphibian populations have been decreasing
around the globe at an unprecedented rate. Batrachochytrium dendrobatidis (Bd), the fungal
pathogen that causes chytridiomycosis in amphibians, is contributing to amphibian declines.
Natural and anthropogenic environmental factors are hypothesized to contribute to these
declines by reducing the immunocompetence of...
