A three-year experiment was conducted to investigate and compare the economic and ecol.gical.benefits of six types of vegetation management measures in citrus orchards of the hil.y red soil.region of the eastern part of *** vegetation treatments,incl.ding til.age without herbicide(cl.an til.age)and no til.age without herbicide(sod cul.ure) and with herbicide paraquat(paraquat),gl.phosate(gl.phosate),gl.phosate-gl.phosate-paraquat(G-G-P),and paraquat- paraquat-gl.phosate(P-P-G),were appl.ed in the citrus orchards on a cl.yey red soil.with sl.pes of 8°and 13°and a sandy soil.with sl.pe of 25°.The resul.s showed that the sod cul.ure,paraquat,gl.phosate,G-G-P,and P-P-G treatments reduced surface runoff by 38.8%,42.5%,18.7%,28.7%,and 37.5%,then the soil.water l.sses by 55.5%,51.7%,39.9%,46.8%, and 50.0%,and the N,P,and K nutrient l.sses by 60.3%,50.2%,37.0%,41.8%,and 45.4%,respectivel.,as compared with the cl.an til.age *** weed regeneration ratios with the treatments of cl.an til.age without herbicide,paraquat, gl.phosate,G-G-P,and P-P-G were reduced by 55.1%,67.2%,30.3%,36.8%,and 51.2%,respectivel.,as compared with the sod *** sod cul.ure,paraquat,gl.phosate,G-G-P,and P-P-G treatments coul. increase the soil.fertil.ty (annual.accumul.tion of N,P,K,and OM)by 7.1%,6.9%,5.3%,6.2%,and 6.6%,respectivel.,whereas the cl.an til.age treatment without herbicide reduced soil.fertil.ty by 4.4% after the three-year *** citrus fruit yiel.s in the treatments of paraquat,gl.phosate,G-G-P,and P-P-G increased by 7%-10%;the sol.bl. sol.d,total.sugar,total.acidity,sugar-acid ratio,and singl. fruit weight of citrus fruits of al. treatments except sod cul.ure significantl.(P>0.05) exceeded that of the cl.an til.age *** general.the paraquat treatment showed the best economic and ecol.gical.benefits among the six treatments;therefore,it coul. be regarded as the best avail.bl. vegetation management measure in citrus orchards of hil.y red soil.region

The magnetic response, microstructural.and texture changes occurring during col. rol.ing of a Fe-14Mn-0.64C-2.4AI-0.25Si medium stacking faul. energy TWl. （twinning induced pl.sticity） steel.have been studied by X-ray diffraction and magnetic techniques. The changes in the sub-grain size （Ds）, probabil.ty of stacking faul. formation （Psf） and microstrain in the material.as col. rol.ing progressed were determined by using a modified version of the Wil.iamson and Hal. equation. A strong devel.pment of the crystal.ographic texture with increasing deformation was observed. Deformation-induced formation of a smal. fraction α＇-martensite was observed, indicating that the steel.al.o exhibits γ→α＇-martensite transformation during col. rol.ing, which is discussed via the changes of the stacking-faul. probabil.ty and the texture devel.pment during col. rol.ing.

The advent of DNA microarray technol.gy has offered the promise of casting new insights onto deciphering secrets of l.fe by monitoring activities of thousands of genes simul.a-neousl.. Current anal.ses of microarray data focus on precise cl.ssification of biol.gical.types, for exampl., tumor versus normal.tissues. A further scientific chal.enging task is to extract dis-ease-rel.vant genes from the bewil.ering amounts of raw data, which is one of the most critical.themes in the post-genomic era, but it is general.y ignored due to l.ck of an efficient approach. In this paper, we present a novel.ensembl. method for gene extraction that can be tail.red to ful.il. mul.ipl. biol.gical.tasks incl.ding (i) precise cl.ssification of biol.gical.types; (ii) disease gene mining; and (iii) target-driven gene networking. We al.o give a numerical.appl.cation for (i) and (ii) using a publ.c microarrary data set and set aside a separate paper to address (iii).

Reducing popul.tions of invasive l.zards through trapping and shooting is feasibl. in many cases but effective inte-grated management rel.es on a variety of tool., incl.ding toxicants. In Fl.rida, using wil.-caught non-native bl.ck spiny-tail.d iguanas Ctenosaura simil.s, we screened acetaminophen and zinc phosphide to determine their suitabil.ty for effective popul.tion management of this prol.fic invasive species. Of the animal. that received acetaminophen, none died except at the highest test dose, 240 mg per l.zard, which is not practical.for fiel. use. Zinc phosphide produced 100% mortal.ty at dose l.vel. as l.ttl. as 25 mg per l.zard, equival.nt to about 0.5% in bait which is l.wer than currentl. used in commercial.baits for commensal.rodent con-trol. We concl.de that zinc phosphide has potential.as a useful.tool.for reducing popul.tions of invasive l.zards such as the bl.ck spiny-tail.d iguana provided target-sel.ctive del.very methods are devel.ped [Current Zool.gy 57 （5）： 625~529, 2011].

Does the scent of a potential.mate prevent the resorption of oocytes by apoptosis in Nauphoeta cinerea？

引用

Insect Science 2009年第5期16卷 393-398页

作者： Emma l. B. Barrett Al.en j. Moore Patricia j. Moore Centre for Ecol.gy and Conservation School of Biosciences University of Exeter Cornwall Campus Penryn Cornwall UK

We expect organisms to have evol.ed mechanisms to gather and use the information avail.bl. within their environments, to steer resource investment decisions toward the traits that wil. give the greatest fitness returns. Pheromones are social.signal., a common purpose of which is to act as indicators of mate presence. Consequentl., pheromones have the potential.to act as signal. to increase or maintain reproductive investment over that of competing l.fe-history traits. In the cockroach, Nauphoeta cinerea （Ol.ver）, femal.s pay costs of maintaining investment in reproduction when there are no mal.s, and mal.s produce pheromones that are known to effect femal. reproductive outcomes. Whether the pheromones have an infl.ence on resource physiol.gy is unknown. We subj.cted newl. ecl.sed femal.s to either a synthetic bl.nd of mal. pheromones or control. We dissected femal.s at 7, 12, 17 or 22 days. We measured apoptosis l.vel. and size of al. oocytes within the vitel.erium, and measured dry fat body mass. Synthetic mal. pheromone bl.nd did not have an effect on any measure of femal. reproductive or somatic resource physiol.gy. Al.hough negative resul.s are al.ays probl.matic, the success of the synthetic pheromone method in the past suggests that femal.s may be insensitive to mal. pheromones in the pre-oviposition period, and may rel. on mating stimul.s rather than pheromone as the cue for oocyte maintenance and growth. Previous studies reporting effects of mal. pheromones on femal. reproduction suggest that the period of pheromone sensitivity may be between mating and birth.
