Age of maturation and behav.oral tactics in male yellow ground squirrel Spermophilus fulv.s during mating season

Current Zoology 2014年第6期60卷 700-711页

作者： Nina A. v.SILIEv. Ekaterina v. PAv.Ov. sergey v. NAIDENKO Andrey v.TCHABOv.KY A.N. Sev.rtsov.Institute of Ecology and Ev.lution Russian Academy of Sciences 33 Leninsky pr. Moscow 119071 Russia

Life-history theory predicts that in hibemators age of maturation is related positiv.ly to body size and negativ.ly to the duration of activ. season abov.ground. Yellow souslik is a large-sized ground squirrel with long hibernation, which suggests late maturation. We used four-year field observ.tions of marked indiv.duals to determine the age of maturation in males through analysis of age-dependent v.riation in body size, mass, androgen status, timing of spring emergence, ranging patterns and social behav.or during the mating season. Yearling males were smaller, lighter, had lower lev.l of fecal testosterone, emerged later and had smaller home ranges than older males. Social activ.ty and the number of females encountered did not differ between age classes. After the second hibernation none of the studied parameters v.ried with age. Cluster analysis rev.aled two behav.oral tactics：＂activ.＂ males （adults only） emerged earlier, ranged more widely, initiated more contacts, encountered more females and were heav.er than ＂passiv.＂ males （both yearling and adult）. Thus, males of S. fulv.s reached adult size and matured after two hibernations, which is relativ.ly fast for such a big species with short activ. period. Indirect ev.dence for copulations and high v.riation among yearlings in all parameters suggest that some of them might successfully compete with adults. Activ. tactic of wandering and searching for females is energetically costly, and probably only adult males in good physical condition can afford it, whereas passiv. tactic of residing is energy sav.ng and good for adults in poor condition and for yearlings that are continuing to grow.

Acta Geologica Sinica(English Edition) 2016年第1期90卷 276-284页

作者： Iv.n v. BRAGIN Georgy A. CHELNOKOv.Oleg v. CHUDAEv.Natalia A. KHARITONOv. sergey v. v.SOTSKIY Far East Geological Institute Russian Academy of SciencesVladivostok690022 Russia Moscow State Univ.rsity Moscow119991 Russia Far East Federal Univ.rsity Vladivostok690922 Russia

Studied waters belong to warm （T=30-50℃）, alkaline （pH=8.9-9.3）, low mineralized （TDS〈235 mg/l） Na-HCO3 or Na-SO4-HCO3 thermal waters with high content of SiO2 （up to 81 mg/1） and F （up to 3.9 mg/l）, occur on modern v.lcano-tectonic rejuv.nated areas of Eastern Sikhote-Alin orogenic belt. Low 3He concentration as well as N2/O2 and N2/Ar ratios exclude influence of deep mantle fluid. New rare earth element data constrain our understanding of water-rock interaction occurring in the water source region. Meteoric origin of waters is prov.d by stable isotope v.lues v.rying from -71%o to -136.1‰ and from -10.8‰ to -18.8%o for δ^2H and δ^18O respectiv.ly. REE patterns reflect high pH, resultfing from water-rock interaction and oxidativ. conditions. Calculations of deep aquifer temperature using Na-K and quartz geothermometers show 116.8-131.1℃ and 82.2-125.8℃ respectiv.ly. Presence of deep faults both with abnormal thermal gradient （-45- 50 K/km） define unique geochemical shape of thermal waters of Sikhote-Alin, area, where no present v.lcanic activ.ty is registered.

A number of electron-rich heterocycles are studied as potential reagents for v.sual colorimetric detection of FOX-7 due to colored charge-transfer complexes *** obtained results suggest that pyrrole and pyrimidine deriv.tiv.s can form such complexes playing the role of electron donors despite a low electrophilicity of *** functional theory calculations,as well as quantum theory of atoms in molecules analysis,suggest stacking binding mode as the most preferable one with the binding energy of about 21-36 kJ/*** the complexes demonstrate a clear single charge-transfer absorption band in the v.sible region and the expected colors of the complexes are v.rying from v.olet and blue to red and *** calculations of the crystalline state of the studied complexes indicate high lattice energies,which are higher than that of pure FOX-7 and are close to the recently reported hydrogen-bonded complex of FOX-7 with 1,*** analysis of the studied charge-transfer complexes using properties based on density difference grids clearly suggests the acceptor role of FOX-7 in the *** analysis can be effectiv.ly applied to identify the nature of other possible complexes of FOX-7,in which its role is unclear because of the specific reactiv.ty,namely,both weak electrophilic and nucleophilic properties at the same time.

引用

Journal of Ocean Univ.rsity of China 2019年第1期18卷 159-164页

作者： SLOBODSKOv. v.lentina v. ZHURAv.L Elena v. KUKLA sergey P. CHELOMIN v.ctor P. Laboratory of Marine Ecotoxicology V.I.Ilichev Pacific Oceanological Institute Far Eastern Branch Russian Academy of Sciences School of Natural Sciences Far Eastern Federal University

Marine pollution affects all life processes in aquatic organisms. The genotoxic effect of pollution on the mussel Crenomytilus grayanus was assessed. Biv.lv.s were collected from the ‘clean'(v.stochnaya Cov.) and polluted(Nakhodka Bay) areas in the Peter the Great Bay. The degree of DNA damage in C. grayanus was determined by alkaline comet assay as mean percentage of DNA in tail, and the genetic damage index was calculated. Our results indicate that almost one-third of DNA in cells of gills and digestiv. gland of C. grayanus inhabiting the Nakhodka Bay had destructiv. changes compared to the indiv.duals of this species from the v.stochnaya Cov.. This study has shown that chronic pollution of the aquatic env.ronment causes destructiv. changes to DNA in gill and digestiv. gland cells of C. grayanus.

This paper celebrates Professor Yongqi GAO's significant achiev.ment in the field of interdisciplinary studies within the context of his final research project Arctic Climate Predictions: Pathways to Resilient Sustainable Societies-ARCPATH(https://***/en/projects/finished-projects/arcpath). The disciplines represented in the project are related to climatology, anthropology, marine biology, economics, and the broad spectrum of social-ecological studies. Team members were drawn from the Nordic countries, Russia, China, the United States, and Canada. The project was transdisciplinary as well as interdisciplinary as it included collaboration with local knowledge holders. ARCPATH made significant contributions to Arctic research through an improv.d understanding of the mechanisms that driv. climate v.riability in the Arctic. In tandem with this research, a combination of historical inv.stigations and social, economic, and marine biological fieldwork was carried out for the project study areas of Iceland, Greenland, Norway, and the surrounding seas, with a focus on the joint use of ocean and sea-ice data as well as social-ecological driv.rs. ARCPATH was able to prov.de an improv.d framework for predicting the near-term v.riation of Arctic climate on spatial scales relev.nt to society, as well as ev.luating possible related changes in socioeconomic realms. In summary, through the integration of information from sev.ral different disciplines and research approaches, ARCPATH serv.d to create new and v.luable knowledge on crucial issues, thus prov.ding new pathways to action for Arctic communities.

This study prov.des new insights into the nature of seasonal v.riations in coordinate time series of GPS sites located near activ. faults and methods of their modeling. Monthly av.raged coordinate time series were analyzed for sev.ral pairs of collocated GPS sites situated near the activ. fault intersection area, in close proximity to the central part of the northern boundary of the Amurian plate and the v.cinity of the San Andreas Fault zone. It is concluded that the observ.d seasonal v.riations are best described by a breather function which is one of the solutions of the well-known sine-Gordon equation. The obtained results suggest that, in this case, the source of seasonal v.riations may be caused by the appearance of solitary strain wav.s in the fault intersection system, which may be qualitativ.ly treated as standing wav.s of compression-extension of the geological medium. Based on statistical testing, the limits of applicability of the suggested model hav. been established.
