The aim of this study was to determine propagation methodology of L. sericea taking into consideration the effect of season and storage. The response of tip and basal cuttings of L. sericea to three hormonal treatments and three growth media was investigated. Seed germination response to five constant temperatures and four pre-sowing treatments was also investigated. Using NMR spectroscopy, the effects of season and storage on metabolites in leaves of L. sericea were investigated. All treatments did not initiate or improve rooting of L sericea cuttings. Seed germination percentage was significantly affected by temperature and pre-sowing treatment compared to control. The optimum seed germination percentage was obtained at 15°C (53%) when treated with smoke water. Seasonal variation affected leaf metabolite profiles. Storage did not affect the antibacterial activity of L. sericea leaves and those harvested in winter showed an MIC value of ≤3.90μg/mL when tested on Propionibacterium acnes / Agriculture, Animal Health and Human Ecology / M.

Benthic invertebrates inhabiting boreal rivers are exposed to very large seasonal variations in their physical environment. The extremes are in winter when the littoral area freezes solid and in spring when water flow increases rapidly. In the North Swedish river Vindelälven, the invertebrates fell into three main categories according to their seasonal lateral distribution. One category of animals was stationary in the littoral zone and let itselt freeze into the ice, adopting a "take it" alternative. The category consisted of many species belonging to several higher taxa. By overwintering in ice, the animals avoided predation for nearly half the year and they were in the productive littoral at the same time as they thawed out from the ice in spring. On the other hand the animals had to withstand sub-zero temperatures. A typical representative for this category of animals was the semivoltine snail Gyraulus acronicus. It is a less mobile species connected to dense stands of macrophytes, which are found only in the littoral zone of the river. Nearly the whole population was found overwintering successfully enclosed in ice. Its shell and epiphragm could serve as mechanical protection when frozen into the ice. G. acronicus was cold-hardy only during late autumn and early winter, but it could stand prolonged sub-zero exposure during the proper time. A second category of animlas avoided being frozen by performing lateral movements to deeper parts of the river, adopting the Vleave it" alternative. No species tested in this category were found cold-hardy. It consisted of mobile species known to utilize sedimentated detritus which was only found in greater amounts in the littoral zone of the river. In springtime, prior to spring flood peak, these species colonized promptly the former frozen zone. This behaviour was most pronounced in several lentie mayfly species. An extreme case of migratory behaviour was found in the mayfly Pararneletus chelifer which not only moved towards the river bank but continued up into small tributaries. The shoreward movements of mayflies both allowed the nymphs to avoid the high current velocities in the central part of the river during spring flood time and to utilize the food resources in the flooded areas. A third category of animals avoided the ice by living stationary in the sublittoral zone, adopting the "never face it" alternative. This category was dominated by filter feeders. / <p>Diss.
