Mammalian hibernation is associated with several events that can affect programmed cell death (apoptosis) in nonhibernators, including marked changes in blood flow, extended fasting, and oxidative stress. However, the effect of hibernation on apoptosis is poorly understood. Here, we investigated apoptosis and expression of proteins involved in apoptotic pathways in intestinal mucosa of summer a...

An unusual abundance of Salmonella infections was studied in an island population of a wild marsupial, the quokka (Setonix brachyurus), which experiences starvation in summer associated with significant mortality. The frequency of infections was found to vary seasonally over most parts of the island, with high infection rates (70 to 100%) in summer and low infection rates (0 to 30%) in winter. ...

Fair and transparent procurement procedures are a cornerstone of a well functioning free-market economy. In particular, bidding is a mechanism whereby companies compete for contracts; when functioning well, the process rewards both the quality of the proposal, and the “reasonableness” of the quote. This way, both the company and the public win. The bidding process requires a fair and transparen...

During summer, there is great spatial variability in bottom water temperature on the northern shelf of Yellow Sea. This associated with a thermal front along shelf. Oscillatory currents from semidiurnal and fortnightly period tides transport masses laterally, resulting oscillations at fixed positions, sometimes large amplitudes. Temperature variations, as demonstrated present work, can cause da...

The thermal stress caused by high temperatures on cut rose flowers grown in greenhouses is a major environmental impact that reduces the yield of growing during summer. To confirm resistance grafted to high-temperature stress, roses were greenhouse summer season and analyzed for yield, quality, root activity, photo-physiological characteristics. A morphological change was observed stomata flowe...
