Phage Intolerance Impacts Antibiotic Susceptibility and Virulence in Staphylococcus aureusNARA Subscribed
Phage therapy is a promising alternative to the growing problem of antibiotic-resistance. However, bacterial phage-resistance may develop, compromising therapy. Phage-resistance has primarily been associated with changes in phage receptors that in the human pathogen, Staphylococcus aureus , are the cell-wall linked wall teichoic acids (WTA) which can be modified by glycosylation. With the aim of identifying factors contributin...
The Uganda National GeneBank is a key reservoir of genetic diversity for sorghum ( Sorghum bicolor (L.) Moench), with over 3333 accessions which are predominantly landraces (96.48%), but also includes the weedy accessions (0.63%), breeding lines (2.5%) and released varieties (0.39%). This genetic resource from the primary center of sorghum diversity and domestication is important for broadening the genetic diversity of elite c...
Manatee behavioral response to boatsNARA Subscribed
The long‐term viability of the Florida manatee is threatened in part by mortality from boat collisions. This study investigated manatee behavior during boat approaches to better understand factors that lead to manatee–boat collisions. Digital acoustic recording tags (DTAGs) and Argos‐linked GPS tags were deployed on 18 manatees in southwest Florida, and boat traffic around them was mapped. Suites of manatee behavioral, environ...
Experimental bleaching of a tropical sea anemone in situNARA Subscribed
Bleaching (whitening) of cnidarians such as corals and sea anemones has caused widespread degradation of coral reefs around the world and is therefore an urgent issue for coral reef science and conservation. Although cnidarians often bleach in aquaria, methods for experimental induction of bleaching in wild cnidarians are lacking, which impedes scientists’ ability to understand the ultimate effects of bleaching on the broader...
This study investigated whether teeth and dorsal fin spines could be used as non‐lethal methods of age estimation for a vulnerable and highly valued tropical fisheries species, coral trout Plectropomus leopardus . Age estimation of individuals from 2 to 9 years old revealed that dorsal spines represent an accurate ageing method (90% agreement with otoliths) that was more precise [average per cent error ( APE ) = 4·1, coefficie...
