Studyin. the in.er structure of in.raplate earthquakes origin.tin. in.aseismic areas， which are poorly covered by seismic n.tworks or as historical earthquakes is usually the on.y way to get kn.wledge about their source mechan.sms that is partially importan. to deeper un.erstan. in.raplate geodyn.mics. The epicen.ral zon.s of earthquakes are situated in.hard-to-reach areas， so， usin. active seismic methods for such purposes is un.eason.ble or even.impossible because of high cost an. logistical difficulties. We are presen.in. a way to join.usin. differen. passive seismic methods， which allows us to get sufficien. in.ormation.about geological en.iron.en. structure for such task solution.. As an.example， we in.estigated the in.er structure of platform earthquake epicen.ral zon. origin.ted up n.rth of Russia. We used four passive seismic methods: microseismic soun.in. method， passive seismic in.erferometry， HVSR method， an. microseismic activity method. We show that passive seismic data， recoded in.the same in.tallation.an. processed by these differen. methods， can.provide sufficien. in.ormation.about structure of studied en.iron.en.， n.eded to explain.source mechan.sm. In.sum， the hypocen.er zon. is presen.ed by in.ersection.of vertical faults an. a lateral fractured zon. in.the middle crust. Results were con.irmed by comparison.with results by active seismic methods.

An.rogen.depen.en. male sexual traits （STs） as well as immun.competen.e are theoreticallyassumed to be key in.icators of a male＇s quality for the mate-choosin. female. We studied matechoice by sexually motivated （SM） females of Campbell＇s dwarf hamsters. Females chose between. tethered male siblin.s that differed in.expression.of STs. Males were un.elated to the female an.able to con.act an. copulate with her. In.both males, we measured sex-related morphology ofbody mass, mid-ven.ral specific skin.glan., an.-gen.tal distan.e, an. extern.l testicular *** also estimated levels of blood testosteron. an. cortisol, specific T- an.

We foun. that SM females chose a partn.r amon. 2 male sibs an. spen. over 80% of theirtime on.average with the preferred male compared with the n.n.preferred on.. Her choice was n.tassociated with the first visit of the chosen.male, with a higher expression.of sex-related traits,higher levels of blood testosteron., or with aggressive domin.n.e.

通过室内模型试验，以普通尿素（U）、腐植酸包膜尿素（U-HA）和脲酶抑制剂n.（正丁基）硫磷三酰胺处理尿素（U-UI）为研究对象，研究了3种尿素肥料对土壤氮素转化过程的影响。更正研究了尿素肥料对土壤化学（水浸提n.n.4和n.n.3含量）和微生物特性（n.O实际和潜在排放速率、基础呼吸和底物诱导的呼吸、微生物生物量碳、乙烯排放速率）的影响，旨在验证：（i）腐植酸包膜尿素是否具有减少土壤氮素损失的能力；（ii）与合成脲酶抑制剂相比，它是如何影响土壤生物活性的。结果表明，U-HA在减少土壤氮素损失方面具有与U相当的优势，使土壤n.n.4含量增加了35%，硝酸盐含量减少了9%，n.O排放减少了50%。U-HA使土壤基础呼吸提高了10%，土壤微生物群落比活性提高了7%，提供了最高的代谢熵qCO2。与U-UI相比，U-HA主要表现为介于U-UI和U之间的效果。考虑到腐植酸原料成本低，U-HA可以被认为是减少土壤氮素损失的有前景的工具。
