Di.toms are uni.ellular algae enclosed i. i.tri.ate bi.-si.i.i.i.d walls wi.h repeti.i.e nanostructures i. a si.e range whi.h makes them potenti.lly relevant for a broad spectrum of i.dustri.l appli.ati.ns. How to opti.i.e the nano-scale structures of the frustule for uti.i.ati.n of di.toms i. nanotechnology i. one of the technologi.al challenges for these appli.ati.ns. Li.ht i. one of the most i.portant abi.ti. factors for algal photosyntheti. growth, and the frustule may play an i.portant role i. medi.ti.g li.ht for these bi.logi.al functi.ns, as well as bei.g central for i.s nano-technologi.al appli.ati.ns. i. thi. study we tested the i.fluence of li.ht quali.y on the nanostructure of the frustule of Cosci.odi.cus grani. and compared thi. to growth rate response. The results showed that colored li.ht （red, yellow, green and blue） at 300μmol photons m-2-s-1 resulted i. a stati.ti.ally si.ni.i.ant change i. nanostructure compared to whi.e li.ht. Green li.ht at 100 μmol photon m-2.s-1 led to a si.ni.i.ant decrease i. mean frustule di.meter and mean foramen di.meter. Numeri.al si.ulati.ns confi.med that the morphologi.al changes obtai.ed were suffi.i.nt to i.duce clear di.ferences i. the photoni.s properti.s of the frustule. The wavelength had no effect on the growth rate at hi.h li.ht i.tensi.y （300 μmol photons m-2.s-1）. However, at 100 μmol photons m-2.s-1, yellow, red-orange and green li.ht resulted i. si.ni.i.antly lower maxi.um growth rates than the other wavelengths. Thi. response of the frustule structure to di.ferent li.ht treatment i.di.ates the possi.i.i.y of a li.ht-based frustule nanostructure mani.ulati.n method, whi.h i. si.ple and envi.onmentally fri.ndly.

The mai. speci.s composi.i.n dri.ers i. temperate deci.uous forests are envi.onmental condi.i.ns, a stand?s age and the si.e hi.tory, e.g., the successi.n stage and past land use, as well as di.turbance regi.e and current management. We compared plant speci.s di.ersi.y and composi.i.n i. late successi.nal and anci.nt forests, cooccurri.g on the same small ri.er i.land applyi.g speci.s accumulati.n curves and nonmetri. multi.i.ensi.nal scali.g, respecti.ely. Gi.en the i.land?s geomorphologi.al characteri.ti.s, we expected these to be very si.i.ar before human i.terventi.n i. the past. The forests experi.nced di.feri.g di.turbance regi.es i. the past, whi.e over the last 30 years, human i.terventi.n has been the same and reduced to a mi.i.um. The anci.nt forest i. thi. study had two major characteri.ti.s defi.i.g i. as old, mature forest: conti.ui.y of presence for more than 200years and speci.i. composi.i.n. The late successi.nal forest experi.nced major di.turbance i. the 20th century and was allowed natural regenerati.n by borderi.g on the anci.nt forest, representi.g a potenti.l speci.s pool,and by decades of mi.i.um human i.terventi.n. Our results showed that, even though there was no di.ference i. speci.s ri.hness, we could sti.l detect di.ferences between the forests, parti.ularly i. the abundance and speci.s composi.i.n of the understorey, among whi.h geophytes had the most i.di.ati.e i.portance. To make our results useful on a broader scale, we composed from the li.erature a speci.s li.t of plants i.di.ati.e for anci.nt forest and tested i.s appli.ati.n. These results are i.portant for di.ti.gui.hi.g between old and mature secondary stands and parti.ularly for i.enti.yi.g old forest stands, whi.h should be conserved and, i. the case of fragmented landscapes, i.cluded i. a network connecti.g forest fragments.

为提高西洋参的经济价值,本研究以西洋参为原料,利用裂褶菌固态发酵西洋参,提高西洋参中活性成分的含量,并对发酵工艺进行优化。本研究以西洋参中总人参皂苷含量为指标,先从3种裂褶菌菌株中筛选出2号菌株作为固态发酵西洋参用菌。再对影响裂褶菌西洋参发酵物的总人参皂苷含量的4个因素(发酵温度、裂褶菌接种量、pH和发酵时间)进行单因素实验。在此结果基础上,利用响应面Box-Behnken试验设计进一步优化裂褶菌固态发酵西洋参工艺,确定优化后的工艺条件为:裂褶菌接种量10.90%,发酵温度31℃、发酵时间10 d,发酵pH5.9。在上述条件下,裂褶菌西洋参发酵物的总人参皂苷含量为10.28%,粗多糖含量为12.85%,总黄酮含量为0.67%,均比未发酵西洋参的高。并且大分子人参皂苷Rb1、Rg_(2)和Re含量降低,小分子人参皂苷Rg_(1)、Rc、Rb_(2)、>、Rd、Rg3、s-Rh_(2)、r-Rh_(2)和拟人参皂苷CK含量升高。其中,稀有人参皂苷Rg_(3)、s-Rh_(2)、r-Rh_(2)和拟人参皂苷CK为新出现皂苷。体外抗氧化实验表明裂褶菌西洋参发酵物的DPPH和ABTs^(+)自由基清除能力的i._(50)值分别为31365和10910μg/mL,均强于未发酵西洋参。本研究证明了裂褶菌固态发酵西洋参提高了总人参皂苷、粗多糖、总黄酮和稀有人参皂苷的含量,增强了抗氧化能力,为西洋参的开发利用提供数据支持。

Androgen-dependent male sexual trai.s （sTs） as well as i.munocompetence are theoreti.allyassumed to be key i.di.ators of a male＇s quali.y for the mate-choosi.g female. We studi.d matechoi.e by sexually moti.ated （sM） females of Campbell＇s dwarf hamsters. Females chose between2 tethered male si.li.gs that di.fered i. expressi.n of sTs. Males were unrelated to the female andable to contact and copulate wi.h her. i. both males, we measured sex-related morphology ofbody mass, mi.-ventral speci.i. ski. gland, ano-geni.al di.tance, and external testi.ular *** also esti.ated levels of blood testosterone and corti.ol, speci.i. T- and B-cell i.mune re-sponses to anti.ens, as well as aggressi.e and sexual domi.ance i. si.li.g males through add-i.i.nal encounter experi.ents wi.h another sM female （male si.s could freely compete for thefemale）. We found that sM females chose a partner among 2 male si.s and spent over 80% of thei.ti.e on average wi.h the preferred male compared wi.h the non-preferred one. Her choi.e was notassoci.ted wi.h the fi.st vi.i. of the chosen male, wi.h a hi.her expressi.n of sex-related trai.s,hi.her levels of blood testosterone, or wi.h aggressi.e domi.ance.

The only character that unambi.uously i.fluenced female choi.e was the non-aggressi.e male to female groomi.g duri.g sexual contact.
