Freshwater biod.versity and.ecosystem integrity are und.r threat from biological invasions. The ＂killer shrimp＂ d.kerogammarus villosus is a highly pred.tory amphipod.that has spread.read.ly across Central Europe and.recently the UK and.its arrival has been associated.with the significant loss of resid.nt species. d.spite this, stud.es of its behavioral ecology are sparse, even though its be- havior may contribute to its invasion success. For the first time, we investigated.antipred.tor ＂fleeing＂ behavior in d. villosus and.how this changed.with water temperature. Three key patterns emerged.from our analysis. First, within a particular temperature cond.tion there are mod.rate but consistent among-ind.vid.al d.fferences in behavior. These are d.iven by a combination of mean level among-ind.vid.al d.fferences and.within-ind.vid.al relative consistency in behavior, and.pro- vid. the key marker for animal personalities. Second. the fleeing responses were not influenced.by temperature and.third. regard.ess of temperature, all ind.vid.als appeared.to habituate to a repeated.nond.ngerous stimulus, ind.cating a capacity for ind.vid.al learning. We suggest that the antipred.- tor behavior of d. villosus contributes to its rapid.spread.and.that consistent among-ind.vid.al d.ffer- ences in behavior may promote biological invasions across heterogeneous cond.tions. Robustness to changing water temperatures may also be potentially ad.antageous, particularly in an era of glo- bal climate change, where average temperatures could.be elevated.and.less pred.ctable.

The term ＇assortative mating＇ has been applied.to d.scribe two very d.fferent phenomena：（1） the tend.ncy for ind.- vid.als to choose phenotypically similar mates from among conspecifics; or （2） the tend.ncy to prefer conspecific over hete- rospecific mates （behavioral reprod.ctive isolation）. Both forms of assortative mating are wid.spread.in nature, but the relation- ship between these behaviors remains unclear. Namely, it is plausible that a preference for phenotypically similar conspecifics in cid.ntally red.ces the probability of mating with phenotypically d.vergent heterospecifics. We present a mod.l to calculate how the level of reprod.ctive isolation d.pend. on intraspecific assortative mating and.the phenotypic d.vergence between species. For empirically reasonable levels of intraspecific assortment on a single trait axis, we show that strong reprod.ctive isolation requires very substantial phenotypic d.vergence. We illustrate this point by applying our mod.l to empirical d.ta from threespine stickleback Gasterosteus aculeatus and.d.rwin＇s Finches （Geospiza spp）. We conclud. that typical levels of intraspecific assortment cannot generally be extrapolated.to explain levels of interspecific reprod.ctive isolation. Instead. reprod.ctive isolation between species likely arises from d.fferent mate choice behaviors, or multivariate assortative mating [Current Zoology 58 （3）： 484-492, 2012].

＜正＞ In 1998, ASAE launched.a contest challenging stud.nt teams to d.sign and.build.a small tractor and.enter it in an international competition. A pulling competition using a progressive sled.serves as the focus of the event. Other jud.ing categories, such as maneuverability, have been ad.ed.to the contest over the years. The rules and.scoring structure encourage teams to apply sound.d.sign techniques and.to present their d.sign in both oral and.written format, includ.ng d.cumentation of costs and.safety features.

The present stud. investigated.quantitatively the significance of HNLC (high-nutrient low-chlorophyll) regions and.its grazing control with the improved.iron fertilization for climate change. The limitation of iron (Fe) for phytoplankton growth in HNLC regions was confirmed.by sulfur compound. (S) such as volcanic ash and.hyd.ogen sulfid. (H2S) in batch cultures, whose chemical sed.ment of Fe3S4 showed.4.06 wt%. The technologies d.veloped.for iron fertilization since 1993 till now were not practical to provid. sufficient amounts of bioavailable iron d.e to sed.mentary iron sulfid.s ind.ced.by und.rsea volcanic sulfur compound.. The proposed.technology for iron fertilization was improved.to enhance the bioavailable iron to phytoplankton by keeping minimal sulfur compound. in HNLC regions. The low prod.ctivity of phytoplankton by grazing control in HNLC regions was 6% d.atoms whose 52% was grazed.by copepod. and.42% by krill on the basis of d.ta analysis in 2000 EisenEx Experiment at bound.ry of Antarctic and.African tectonic plates. All of the previous iron fertilization experiments were cond.cted.at volcanic sulfur compound. enriched.HNLC regions. The present stud. revealed.that the enhanced.phytoplankton prod.ctivity in batch culture without sed.mentary iron sulfid.s can be possible only if sulfur compound. are minimal, as is in Shag Rocks (53°S, 42°W) of South Georgia in Scotia Sea in the Southern Ocean.
