Ingani katsi dzinorara: zvese nezve pet modhi

Chokwadi katsi mhuka dzeusiku here? Vazhinji vavo vanodzungaira mumakamuri ane rima emba yekurara pakati petatu nechina mangwanani uye vangada kanenge kamwe kanguva kadiki.

Pasinei nokusaremekedza kwakajeka kwekatsi kune nzira yekurara kwevanhu, chaizvoizvo haisi yeusiku, asi mhuka dzemasikati. Ichi chikamu chebhayoroji chinosanganisira mhuka dzinonyanya kushingaira mambakwedza nemasikati, inotsanangura Amai Nature Network. Mhuka zhinji dzakasimba, kubva kutsuro kusvika kushumba, dzakashanduka-shanduka kuti dzirarame apo tembiricha yakanga yakadzikira kwazvo munzvimbo yadzo yerenje.

Kuziva maitiro akajairwa ehunhu hwemambakwedza - kuputika kwesimba kupfupi kunoteverwa nenguva refu yekuzorora - kuchabatsira kunzwisisa kuti nei chikamu chepamusoro chekutamba kwekatsi kuchiwanzo kuitika panguva chaiyo apo munhu akarara.

manheru mhuka

Chokwadi mhuka dzeusiku, dzakadai semhungu nemazizi, dzinogara dzakamuka usiku hwose uye, dzichishandisa rima, dzinovhima mhuka dzadzo. Mhuka dzemazuva ese dzakaita setsindi, butterflies uye vanhu vanoshanda mashifiti ezuva. Asi mhuka dze crepuscular dzinoshandisa mukana wechiedza chemasikati uye rima riri kupera kuti zviite zvakanakisisa zvemasikati neusiku.

“Pfungwa inonyanya kutaurwa yezvinoita crepuscular basa ndeyokuti inopa dzikamo yakakwana,” inotsanangura kudaro BBC Earth News. “Panguva ino, kwakareruka zvekukwanisa kuona, uye kunenge kwasviba zvakakwana, izvo zvinoderedza mukana wekubatwa nekudyiwa.” Mhuka dzinodya dzimwe mhuka dzakaita serukodzi hadzioni zvakanaka munguva dzerubvunzavaeni, zvichiita kuti zviomerwe kubata zvisikwa zviduku uye zvinonaka zvemambakwedza.

Kunyange zvazvo maitiro aya ari echisikigo kumarudzi ose, mararamiro emhuka iyi usiku, masikati, kana crepuscular inonyanya kusarudzwa nemaitiro emaziso ayo. Mune zvimwe zvisikwa zvemambakwedza, zvakaita sekatsi, retina ine chimiro chakadambuka, semhuka dzeusiku. Izvi zvinotsanangura chikonzero nei kunyangwe mukamuri rakasviba zvakanyanya, zviri nyore kwaari kuti abate chigunwe chemuridzi wake kutamba.

"Vertical palpebral fissure inowanzowanikwa muzvikara zvakavandira," Martin Banks, nyanzvi yezvemaziso, akaudza National Public Radio (NPR). The vertical slit ine "optical features inoita kuti ive yakanaka" kune katsi dzinomirira dzisati dzasvetukira pamhuka dzadzo. Mukati, maitiro aya anogona kazhinji kuonekwa manheru kana mambakwedza.

Kuvata kana kusavata

Kunyangwe katsi dzakarongerwa biologically kuti dzishande zvakanyanya manheru, dzimwe dzadzo dzinofarira kumhanya amok mukati memaawa. Mushure mezvose, hazvigoneki kuti kati ichafara zvikuru kana ikarara kwemaawa gumi nematanhatu mumutsara. Zvipfuyo zvakawanda zvinomutsa varidzi vazvo kamwe chete husiku. Varidzi havazvifariri. Iyi ndiyo nzira yemapranks eusiku inowanzomutsa mubvunzo wekuti, "Katsi imhuka dzeusiku zvechokwadi here?"

Nzira yekurara yekati inoita basa rinokosha. Kurara nekuzorora hazvina kufanana kumhuka sezvazviri kune varidzi vadzo, anotsanangura kudaro Animal Planet. Katsi “dzine hope dzeREM uye dzisiri dzeREM, asi pane chimwe chezvikamu izvi katsi inovharika zvachose.” Katsi dzinogara dzakangwarira, kunyange padzinenge dzakarara.

Kana vakamutswa noruzha rwechienzi, vanomuka nokukurumidza uye vakagadzirira zvakakwana kuita chiito. Ndiko kugona uku kunobvumira katsi nemhuka dzesango zvakazara kuti dzigare dzakachengeteka uye dzichitsvaga chikafu chadzo muzvisikwa. Varidzi vazhinji vakacherekedza mamiriro ezvinhu apo shamwari dzavo dzine furry, dzakarara kune imwe mugumo wekamuri, dzakanga dziri pedyo nemumwe sekondi gare gare, zvaingodiwa kuvhura gaba rechikafu nekudzvanya.

Katsi dzemumba hadzichadi kuvhima kuti dziwane chikafu chadzo, asi izvi hazvireve kuti njere idzi dzakanyangarika. Sokutaura kwakaita purofesa we<em>genetics Dr. Wes Warren ku<em>Smithsonian Magazine, “katsi dzakachengeta unyanzvi hwadzo hwokuvhima, saka hadzinyanyi kutsamira kuvanhu nokuda kwezvokudya.” Ndokusaka katsi ichinyatso "kuvhima" matoyi ake, chikafu uye katsi kubata.

Masikirwo ekuvhima kwekatsi akabatana zvisingaite nehunhu hwayo hwemambakwedza, izvo zvinotungamira kumhando dzinoshamisa dzemaitiro mumba. Inofanana nemaitiro emadzitateguru ake emusango - seshumba diki inogara mufurati.

Kurara kwekudzorera

Pfungwa ye "kurara kwekatsi" - kurara kwenguva pfupi yekupora - yakaonekwa nechikonzero. Katsi inorara zvakanyanya. Munhu mukuru anoda maawa gumi nematatu kusvika gumi nematanhatu ekurara husiku hwese, uye katsi nekatsi diki kusvika maawa makumi maviri. 

Katsi “dzinodurura” zvokudya zvadzo munhambo inopfuurira yemaawa 24 yenhambo pfupi yokurara panzvimbo pokurara kwenguva refu kumwe chete. Vanonyanya kushandisa zviroto izvi, vachichengeta simba rekushandisa panguva dzebasa repamusoro. Ndicho chikonzero katsi inorara zvakasiyana nezvatinoita - purogiramu yake yakavakwa nenzira yakasiyana zvachose.

Kunyange zvazvo nguva dzekatsi dzekuita dzingave pfupi, dzakanyanya. Kufanana nemhuka dzese dzemambakwedza, shamwari inobereka mvere inyanzvi pakuunganidza uye kushandisa simba rayo. Kuti ishandise zvakanyanya nguva idzi dzekuita, katsi inofanira kusunungura simba rose uye ichatsvaga varaidzo isinganeti. Pamwe achatyaira mabhora ake anorira achitenderedza imba kana kukanda mbeva yekutambisa nekatsi mudenga. Panguva imwecheteyo, anogona kuita akasiyana pranks mumba, saka iwe unofanirwa kunyatso mutarisisa kudzivirira hooligan kukwenya uye kuda kuziva kunokuvadza.

Nguva dzakasimba dzakadaro dzichapa varidzi mukana wekudzidza maitiro ekati uye kuiona mukuita. Anotarisa nokushivirira chitoyi chakapfava kwehafu yeawa asati atunda here? Ari kudongorera pakona, achinyahwaira achibata kunge angabhururuka achienda? Makapeti anopeta anova impromptu mink yecrispy mabhora? Zvinonakidza kuona kuti katsi yemumba inotevedzera sei hunhu hwehama dzayo dzemusango.

Dzimwe katsi dzinogona kukwirisa, zvisinei nekuti masikirwo kana dzinza rinoraira kwavari. Asi katsi dzese dzakanakisa pakuchengeta simba uye nekurishandisa nemazvo sezvinobvira panguva yekushanda. Inguva dzerubvunzavaeni dzinoratidza hunhu hwavo hwakajeka.
