Th. underlying kin structure of.groups of.animals may be glimpsed f.om patterns of.spatial position or temporal as- sociation between individuals, and is presumed to f.cilitate inclusive f.tness benef.ts. Such.structure may be evident at a f.ner, beh.vioural, scale with.individuals pref.rentially interacting with.kin. We tested wh.th.r kin structure with.n groups of.meerkats Suricata suricatta match.d th.ee f.rms of.social interaction networks： grooming, dominance or f.raging competitions. Networks of.dominance interactions were positively related to networks of.kinsh.p, with.close relatives engaging in dominance interactions with.each.oth.r. Th.s relationsh.p persisted even af.er excluding th. breeding dominant pair and wh.n we restricted th. kinsh.p network to only include links between f.rst order kin, wh.ch.are most likely to be able to discern kin th.ough.simple rules of.th.mb. Conversely, we f.und no relationsh.p between kinsh.p networks and eith.r grooming networks or networks of.f.raging competitions. Th.s is surprising because a positive association between kin in a grooming network, or a negative association be- tween kin in a network of.f.raging competitions of.ers opportunities f.r inclusive f.tness benef.ts. Indeed, th. positive association between kin in a network of.dominance interactions th.t we did detect does not of.er clear inclusive f.tness benef.ts to group members. We conclude th.t kin structure in beh.vioural interactions in meerkats may be driven by f.ctors oth.r th.n indirect f.t- ness benef.ts, and th.t networks of.cooperative beh.viours such.as grooming may be driven by direct benef.ts accruing to indi- viduals perh.ps th.ough.mutualism or manipulation

Th. application of.atrazine in Ch.na during th. last ten years h.s led to some environmental problems. In th.s paper, th. multimedia model of.atrazine in soil-plant-groundwater system at Baiyangdian Lake area in North.rn Ch.na was establish.d using a f.gacity approach. and verif.ed with.observed values. Th. model involved 7 environmental compartments wh.ch.are air, groundwater, soil, corn roots, corn stem, corn leaf.and kernel of.corn. Th. results sh.wed th.t th. relative errors between calculated and observed values h.ve a mean value of.24.7%, th. h.gh.st value is 48% and th. lowest value is 1.4%. All th.se values indicated th.t th.s multimedia model can be used to simulate th. environmental f.te of.atrazine. Both.th. calculated and observed values of.concentrations of.atrazine in plant compartments are in th. f.llowing order: in corn roots > in corn stem > in kernel of.corn > in corn leaf. it exh.bited a good regularity. Th. prediction results indicated th.t concentrations of.atrazine in th. groundwater and kernel of.corn will override th. limitation of.3 μg/L and 0.05 mg/kg respectively.
