Intraspecific kulimbana: zitsanzo ndi mbali

Kulimbana kuli mwa mitundu kuyambira akale chikhalidwe yaikulu kusankha zamoyo. Zimachitika ndi pa siteji lino la chitukuko cha moyo. Komanso, zingaoneke osati kuthengo, komanso mmadera. ndi intraspecific iti? Zitsanzo ndi mbali zake m'nkhani yathu.

NKHANI intraspecific nkhondowo

Onani taxon zing'onozing'ono nyama ndi zomera. Izi zikuphatikizapo anthu ofanana mu muyezo morphological ndi anatomical, amene mwaulere interbreed, kubereka chonde ndi zatenga malo ena. N'chifukwa chiyani pakati pa anthu amene zambiri zofanana, ambiri pali kulimbana? Chinthu kuti iwo amafuna zikhalidwe zomwezo wa moyo. Ndipo mkati mwa malo ochepa amene amakhala chilengedwe chuma kwambiri okha. N'chifukwa chake chabwino pamoyo ayenera kukhala ndi umboni. Intraspecific kulimbana, zitsanzo zomwe m'nkhani kumabweretsa kusankha zamoyo. Chifukwa cha kupulumuka wake wa Zamphamvu lapansi.

Kulimbana amapereka mphamvu

Pakuti angakhale akuvutika anthu mitundu chomwecho? Makamaka chakudya. Ndi kwambiri zambiri konse si kokwanira. Tambala zambiri n'kumamujompha mwendo imfa abale ofooka, kudya kafadala anaika mazira - onse zitsanzo za intraspecific yolimbirana kukhalapo. Kungakhale onse khalidwe payekha ndi gulu. The zamoyo zinachita kusintha wotchuka Charles Darwin ankakhulupirira kuti mpikisano trophic - ichi ndi ambiri pachimake intraspecific kulimbana. Zitsanzo za izo ndi lambiri: mimbulu mabanja kuteteza dziko lawo ku magulu, gulls kukankhira kunja kwa chisa ofooka anapiye a kadzidziyo, mitengo ndi kufalitsa korona kuyamwa kuchuluka wamkulu wa dzuwa mphamvu, kuwamana zomera zina zinthu dzuwa.

Mwachibadwa kugonana

Pa nyengo kuswana, nyama ambiri makamaka kutchulidwa kwa ogwetsana mkazi pakati pa anthu a mitundu chomwecho. Mu chikhalidwe mokwanira anayamba dimorphism kugonana. Yankholo mu kusiyana morphological pakati pa amuna ndi akazi yoperekedwa kwa mtundu womwewo. Yotsirizira ndi maonekedwe owala kukopa mkazi. Kumbukirani nthenga zokongola roosters, yowala mtundu nsomba Aquarium guppy, mchira kaso pikoko a, yapamwamba tsitsi mkango. mbali zonse izi wokongola kokha awa mitundu ya amuna. Ndipo iwo amakonzedwa, mwayi kwambiri kukopa wamkazi. Zonsezi ndi zitsanzo za intraspecific yolimbirana kukhalapo.

Ndipo nyama zina kukhwimitsa kwambiri nkhondo mwayi kubereka. Roosters kwenikweni kukonza ndewu, nthawi zina polimbana ndi mzake anavulala kwambiri. Ngakhale chete kamba mating nyengo ndi mwamakani, kuchita ndewu. Pasanathe aukali njoka. Adders kupanga otchedwa "mipira mating" basi, n'kusokoneza mzake. mbalame amuna ambiri kukopa zazikazi ndi kuyimba. Dokowe amasankha kagawo kugogoda adalira mlomo ndipo amadikira tsikulo lidzafika nthunzi.

Kufalitsa: amene anali woyamba

Kukula m'dera nawonso kukhala intraspecific kulimbana. Zitsanzo za zomera kuti ubwere mu izo, ambiri ndithu. Tangoganizani kukhala mbali ya nkhalango coniferous yopsereza. Patapita nthawi zina nthaŵi malo awa kachiwiri kuonekere m'nkhalango wamng'ono. Mitengo kukula woyamba, adzakhala nacho chuma kwambiri pa chitukuko cha korona ndi mizu ndipo zatenga malo lalikulu. Ngakhale chomwecho zomera lalikulu masamba mthunzi ang'onoang'ono, kuwapatsa mwayi kwa photosynthesize mwachangu, ndipo Tikatero.

Intraspecific kulimbana zitsanzo za amene asonyezedwa m'nkhani kumabweretsa kusankha zamoyo. Ndi kovuta ndithu, monga anthu akugwirizana yemweyu ndiye adzakhala zikhalidwe zomwezo moyo. Intraspecific kulimbana kumaonekera mwa mawonekedwe a mpikisano trophic, mpikisano akazi pa nyengo mating, ndi Championship mu chitukuko cha dera.
