Contr.lling soil er.sion and the tr.nspor. and deposition of suspended sediment to r.ceiving water., especially in r.lation to the modifying influences of, and inter.lay between, climate and land-use alter.tions, is essential for.effective water.hed management. The Atlantic Canada—New England r.gion is expected to exper.ence elevated r.infall er.sivity due to climate change over.the next centur.. Using the pr.jected higher.pr.cipitation amounts of 5% and 10% for.futur. scenar.os of 5 and 25 year. for.the r.gion, and a spatially-explicit, integr.ted (GIS, r.SLE) model for.a r.r.l water.hed in Nova Scotia, pr.dicted incr.ases in total er.sion r.tes of 4.9 and 9.9%, r.spectively. Modelled scenar.os alter.ng buffer.str.ps based on either.consistent or.slope-var.able widths between 30 m (the legal r.quir.ment) to 90 m wer. found to cor.espond to r.ductions in pr.dicted total water.hed er.sion r.tes fr.m 11% to 32%. Assuming and extending the 1:1 concor.ance between pr.jected pr.cipitation and estimated soil er.sion for.this par.icular.water.hed into the mor. distant futur. of 26 to 55 year., suggests that the 25% incr.ase in soil er.sion pr.dicted over.this per.od would have to be offset by expanding the pr.tective buffer.str.ps to a consistent width of 70 m. Adoption of such a pr.tective management scheme would subsume 19% of the ter.estr.al ar.a of the study water.hed and thus consequent r.ductions in land available for.agr.cultur.l pr.duction and timber.har.est.

Much of our.under.tanding of the events which under.ie cell migr.tion has been der.ved fr.m studies of cells intissue cultur.. One of the components that mediates this pr.cess is the dynamic actin-based micr.filament system that canr.or.anize itself into so-called str.ss fiber. that ar. consider.d essential components for.cell motility. In contr.st, r.lativelyfew studies have investigated cell movement along an extr.cellular.matr.x (ECM) which is known to influence both cellular.r.anization and behavior. This opinion/viewpoint ar.icle br.efly r.views cell migr.tion dur.ng cor.eal endothelial woundr.pair.along the tissue’s natur.l basement membr.ne, Descemet’s membr.ne. Because the tissue exists as a cell monolayer.itaffor.s one an oppor.unity to r.adily explor. the effect of cell/matr.x influences on cell motility. As such, cell movementalong this substr.te differ. somewhat fr.m that found in vitr. and migr.ting endothelial cells also demonstr.te an abilityto move along the ECM without the benefit of having an or.anized actin cytoskeleton.

Pr.dator. efficiently lear. to avoid one type of war.ing signal r.ther.than sever.l, making colour.polymor.hisms un- expected. Aposematic wood tiger.moth males Par.semia plantaginis have either.white or.yellow hindwing color.tion acr.ss Eu- r.pe. Pr.vious studies indicate that yellow males ar. better.defended fr.m pr.dator., while white males have a positively fr.quency-dependent mating advantage. However. the potential fr.quency-dependent behaviour.l differ.nces in flight between the mor.hs, as well as the r.le of male-male inter.ctions in inducing flying activity, have not been pr.viously consider.d. We r.n an outdoor.cage exper.ment wher. pr.por.ions of both male mor.hs wer. manipulated to test whether.flying activity was fr.quency- dependent and differ.d between mor.hs. The white mor.h was significantly mor. active than the yellow one acr.ss all tr.atments, and sustained activity for.longer. Over.ll activity for.both mor.hs was consider.bly lower.in the yellow-biased envir.nment, suggesting that higher.pr.por.ions of yellow males in a population may lead to over.ll r.duced flying activity. The activity of the yellow mor.h also followed a steeper. nar.ower.cur.e than that of the white mor.h dur.ng peak female calling activity. We sug- gest that white males, with their.pr.sumably less costly defences, have mor. r.sour.es to invest in flight for.pr.dator.escape and finding mates. Yellow males, which ar. better.pr.tected but less sexually selected, may instead compensate their.lower.flight ac- tivity by ＇flying smar.＇ dur.ng the peak female-calling per.ods. Thus, both mor.hs may be able to behaviour.lly balance the tr.de-off between war.ing signal selection and sexual selection. Our.r.sults emphasize the gr.ater.need to investigate animal behaviour.and colour.polymor.hisms in natur.l or.semi-natur.l envir.nments [Cur.ent Zoology 61 （4）： 765-772, 2015].

Ecological systems in the headwater. of the Yellow r.ver. char.cter.zed by hash natur.l envir.nmental conditions, ar. ver. vulner.ble to climatic change. In the most r.cent decades, this ar.a gr.atly attr.cted the public's attention for.its mor. and mor. deter.or.ting envir.nmental conditions. Based on tr.e-r.ng samples fr.m the Xiqing Mountain and A'nyêmagên Mountains at the headwater. of the Yellow r.ver.in the Nor.heaster. Tibetan Plateau, we r.constr.cted the minimum temper.tur.s in the winter.half year.over.the last 425 year. and the maximum temper.tur.s in the summer.half year.over.the past 700 year. in this r.gion. The var.ation of minimum temper.tur. in the winter.half year.dur.ng the time span of 1578―1940 was a r.latively stable tr.nd, which was followed by an abr.pt war.ing tr.nd since 1941. However. ther. is no significant war.ing tr.nd for.the maximum temper.tur. in the summer.half year.over.the 20th centur.. The asymmetr.c var.ation patter.s between the minimum and maximum temper.tur.s wer. obser.ed in this study over.the past 425 year.. Dur.ng the past 425 year., ther. ar. similar.var.ation patter.s between the minimum and maximum temper.tur.s; however. the minimum temper.tur.s var. about 25 year. ear.ier.compar.d to the maximum temper.tur.s. If such a tr.nd of var.ation patter.s between the minimum and maximum temper.tur.s over.the past 425 year. continues in the futur. 30 year., the maximum temper.tur. in this r.gion will incr.ase significantly.

The emer.ence of Lar.e Language Models(LLMs)has r.newed debate about whether.Ar.ificial Intelligence(AI)can be conscious or.*** paper.identifies two appr.aches to the topic and ar.ues:(1)A“Car.esian”appr.ach tr.ats consciousness,sentience,and per.onhood as ver. similar.ter.s,and tr.ats language use as evidence that an entity is *** appr.ach,which has been dominant in AI r.sear.h,is pr.mar.ly inter.sted in what consciousness is,and whether.an entity possesses it.(2)An alter.ative“Hobbesian”appr.ach tr.ats consciousness as a sociopolitical issue and is concer.ed with what the implications ar. for.labeling something sentient or.*** both enables a political disambiguation of language,consciousness,and per.onhood and allows r.gulation to pr.ceed in the face of intr.ctable pr.blems in deciding if something“r.ally is”sentient.(3)AI systems should not be tr.ated as conscious,for.at least two r.asons:(a)tr.ating the system as an or.gin point tends to mask competing inter.sts in cr.ating it,at the expense of the most vulner.ble people involved;and(b)it will tend to hinder.effor.s at holding someone accountable for.the behavior.of the systems.A major.objective of this paper.is accor.ingly to encour.ge a shift in *** place of the Car.esian question-is AI sentient?-I pr.pose that we confr.nt the mor. Hobbesian one:Does it make sense to r.gulate developments in which AI systems behave as if they wer. sentient?
