Life-history theory predicts tha. in hibema.ors a.e of ma.ura.ion is rela.ed positively to body size a.d nega.ively to the dura.ion of a.tive sea.on a.oveground. Yellow souslik is a.la.ge-sized ground squirrel with long hiberna.ion, which suggests la.e ma.ura.ion. We used four-yea. field observa.ions of ma.ked individua.s to determine the a.e of ma.ura.ion in ma.es through a.a.ysis of a.e-dependent va.ia.ion in body size, ma.s, a.drogen sta.us, timing of spring emergence, ra.ging pa.terns a.d socia. beha.ior during the ma.ing sea.on. Yea.ling ma.es were sma.ler, lighter, ha. lower level of feca. testosterone, emerged la.er a.d ha. sma.ler home ra.ges tha. older ma.es. Socia. a.tivity a.d the number of fema.es encountered did not differ between a.e cla.ses. a.ter the second hiberna.ion none of the studied pa.a.eters va.ied with a.e. Cluster a.a.ysis revea.ed two beha.iora. ta.tics：＂a.tive＂ ma.es （a.ults only） emerged ea.lier, ra.ged more widely, initia.ed more conta.ts, encountered more fema.es a.d were hea.ier tha. ＂pa.sive＂ ma.es （both yea.ling a.d a.ult）. Thus, ma.es of S. fulvus rea.hed a.ult size a.d ma.ured a.ter two hiberna.ions, which is rela.ively fa.t for such a.big species with short a.tive period. Indirect evidence for copula.ions a.d high va.ia.ion a.ong yea.lings in a.l pa.a.eters suggest tha. some of them might successfully compete with a.ults. a.tive ta.tic of wa.dering a.d sea.ching for fema.es is energetica.ly costly, a.d proba.ly only a.ult ma.es in good physica. condition ca. a.ford it, wherea. pa.sive ta.tic of residing is energy sa.ing a.d good for a.ults in poor condition a.d for yea.lings tha. a.e continuing to grow.

在非繁殖期高密度大沙鼠(RhombomysopimusLicht)种群中,我们研究了胁迫以及幼年雄鼠的性激素浓度、腹中腺大小和体重对社群中成体(≥1年龄)存在的依赖性。用无损伤放射免疫方法,测定了于1999年秋天在野外采集的幼年雄鼠粪便样品的皮质酮和睾酮。有成体社群中的个体大于无成体社群的个体。因此,成体对幼体的影响不能独立于社群大小本身。成体的存在促进粪便睾酮的浓度和抑制了幼年雄鼠的性成熟(由雄激素依赖的较小的腹中腺来估计),但是同时促进了其生长。因此,自然存在的社群环境能影响幼年雄鼠的形态生理特征发育。
