In re.e.t ye.rs, China has be.ome.an incre.singly important and the.large.t che.tnut produce. in the.world.

Chocolate.coating significantly improve. the.nutritional value.of che.tnut. RFDC had high le.e.s of starch (66.23%) and fibe.s (3.85%) while.DCC and MCC containe. significantly high amounts of sucrose. prote.n, fat and mine.als. Furthe.more. the.prote.n conte.t double. in MCC rathe. than in DCC. This could be.attribute. to the.diffe.e.t formulations in the.two products.

The.amino acid profile.showe. diffe.e.ce. in amino acid composition re.ate. to the.sample.s prote.n conte.t, indicating the.r good nutritional quality. The.moisture.conte.ts in all RFDC, DCC and MCC we.e.suitable.for industrial proce.sing. The.e.re.ults provide.information about the.additional nutrie.ts of chocolate.coate. che.tnut and confirm that the.product is an inte.e.ting nutritional food.

Re.e.rch on se.ual se.e.tion and hybridization has focuse. on fe.ale.mate.choice.and male.male.compe.ition. While.the.e.olutionary outcome. of inte.spe.ific fe.ale.pre.e.e.ce.have.be.n we.l e.plore., we.are.now gaining a be.te. unde.standing of the.proce.se. by which male.male.compe. tition be.we.n spe.ie. in se.ondary contact promote. re.roductive.isolation ve.sus hybridization. What is re.ative.y une.plore. is the.inte.action be.we.n fe.ale.choice.and male.compe.ition, as the. can oppose.one.anothe. or align with similar outcome. for re.roductive.isolation. The.role.of fe.ale.fe.ale.compe.ition in hybridization is also not we.l unde.stood, but could ope.ate.similarly to male.male.compe.ition in polyandrous and othe. syste.s whe.e.costs to he.e.ospe.ific mating are.low for fe.ale.. Re.roductive.compe.ition be.we.n e.the. se. of sympatric spe.ie. can cause.the.dive.ge.ce.and/or conve.ge.ce.of se.ual signals and re.ognition, which in turn influe.ce. the.like.ihood for inte.spe.ific mating. Future.work on spe.ie. inte.actions in se.ondary contact should te.t the.re.ative.influe.ce. of both mate.choice.and compe.ition for mate. on hybridization outcome., and should not ignore.the.possibilitie. that fe.ale. can compe.e.ove. mating re.ource., and male. can e.e.cise.mate.choice.

In the.local motion, the.low e.e.gy stars show inte.e.ting re.onance.phe.ome.a, but the.chaotic motion, if any, is ne.ligible.
