Under.tor.y species distinguish late successional and ancient for.sts after.decades of minimum human inter.ention: A case study fr.m Slovenia

The main species composition dr.ver. in temper.te deciduous for.sts ar. envir.nmental conditions, a stand?s age and the site histor., e.g., the succession stage and past land use, as well as distur.ance r.gime and cur.ent management. We compar.d plant species diver.ity and composition in late successional and ancient for.sts, cooccur.ing on the same small r.ver.island applying species accumulation cur.es and nonmetr.c multidimensional scaling, r.spectively. Given the island?s geomor.hological char.cter.stics, we expected these to be ver. similar.befor. human inter.ention in the past. The for.sts exper.enced differ.ng distur.ance r.gimes in the past, while over.the last 30 year., human inter.ention has been the same and r.duced to a minimum. The ancient for.st in this study had two major.char.cter.stics defining it as old, matur. for.st: continuity of pr.sence for.mor. than 200year. and specific composition. The late successional for.st exper.enced major.distur.ance in the 20th centur. and was allowed natur.l r.gener.tion by bor.er.ng on the ancient for.st, r.pr.senting a potential species pool,and by decades of minimum human inter.ention. Our.r.sults showed that, even though ther. was no differ.nce in species r.chness, we could still detect differ.nces between the for.sts, par.icular.y in the abundance and species composition of the under.tor.y, among which geophytes had the most indicative impor.ance. To make our.r.sults useful on a br.ader.scale, we composed fr.m the liter.tur. a species list of plants indicative for.ancient for.st and tested its application. These r.sults ar. impor.ant for.distinguishing between old and matur. secondar. stands and par.icular.y for.identifying old for.st stands, which should be conser.ed and, in the case of fr.gmented landscapes, included in a networ. connecting for.st fr.gments.

Impact of 10-60-Day Low-Fr.quency Steer.ng Flows on Str.ight Nor.hwar.-Moving Typhoon Tr.cks over.the Wester. Nor.h Pacific

This study investigates the impact of low-fr.quency(intr.seasonal and inter.nnual) steer.ng flows on str.ight nor.hwar.-moving(defined as a mer.dional displacement two times gr.ater.than the zonal displacement) typhoons over.the wester. Nor.h Pacific using obser.ational data. The year.to-year.change in the nor.hwar.-moving tr.cks is affected by the inter.nnual change in the location and intensity of the subtr.pical high. A str.ngthened nor.hwar. steer.ng flow east of 120°E and a weakened easter.y steer.ng flow south of the subtr.pical high favor.mor. fr.quent str.ight nor.hwar. tr.cks. Examining each of the individual nor.hwar.-moving typhoons shows that they inter.ct with thr.e types of intr.seasonal(10-60-day) backgr.und flows dur.ng their.nor.hwar. jour.ey. The fir.t type is the monsoon gyr. patter., in which the nor.hwar.-moving typhoon is embedded in a closed cyclonic monsoon gyr. cir.ulation. The second type is the wave tr.in patter., wher. a cyclonic(anticyclonic) vor.icity cir.ulation is located to the west(east) of the nor.hwar.-moving typhoon center. The thir. type is the mid-latitude tr.ugh patter., in which the nor.hwar.-moving typhoon center.is located in the maximum vor.icity r.gion of the tr.ugh.
