Izityalo ngokwabo zizuze izibindi zibe ngamanqatha

Sivame ukucinga ukuba izityalo zinoxolo, kwaye zizilindele ukuba zidle nantoni na. Nangona kunjalo, ezinye izityalo ziye zavelisa indlela enobuchule kunye nezobugcisa bokulwa neentshaba zayo.

Izinto ezikhuselayo

Uphando olutsha lubonise indlela ezinye izityalo ezizikhusela ngayo kwiimveliso zaso: zibenza zibe yizintlu. Iziphumo zophando, ezipapashwe kwiphephancwadi yeNdalo: i-Ecology kunye ne-Evolution, zibonise ukuba izityalo zentamatyambo (Lycopersicon lycopersicum) zivelisa iikhemikhali ezikhuselayo ezibangele izibungu ezinobungozi (iimbhobho ze-beet) zokutya.

Ngokukhawuleza xa izibungu ziqala ukutya amaqabunga alezi zityalo, ezi zikhupha i-organic compound ebizwa ngokuthi i-methyl-jasmonate. Esi sityalo senza isityalo sibe yingozi kakhulu kwiinambuzane, siyinyanzelise ukuba sisebenzise inkunkuma.

Iningi lezinambuzane, njengokuba uyazi, ziba ngamanzi, ukuba kunyanzelekile ukuba zisinde, "kutsho isitatimende somlobi kwintetho uSolwazi uJohn Orrock. - Ukusuka kweso sityalo, oku kuyiphumo elifunayo-ukwenza i-herbivores idle enye. Izinambuzane-izigulane azizuzisi nje kuphela isityalo ngokubulala njengama-herbivores, kodwa aphinde asabonakalisa inzala kumaqabunga ngokwawo, kuba sele sele anelisekile ukulamba kwabo nezinye izibindi. "

Nangona kunjalo, i-methyl-jasmonate inomnye umphumo. Xa olu xhumo luqala ukuphuhliswa, luba ngumsindo wongxamiseko kwizityalo ezingummelwane, uqikelele indlela yokulwa neentshaba. Oku kukhuthaza ezinye izityalo ukuba zisebenzise zonke iindlela zokuzikhusela kwaye ziqalise ukuvelisa iimpahla zazo zokugcina i-methyl-jasmonate.

Iimpawu zonyango

Kungabonakala kungaqhelekanga ukuba iimbumba zilibale ngokutya kwazo izityalo ngokukhawuleza kwaye ziqale ukuzingela, kodwa abaphandi bachaza ukuba inkunkuma yinkemba ephindwe kabili enokubangela inzuzo kwintlobo yezilwanyana kunye nokuyingozi.

"I-Cannibal, e neneni, ifumana umthombo" wokutya okufanelekileyo, "- ichaza kwingxelo yakhe, uNjingalwazi onxulumene noBret Elderd. - Ixhoba le-cannibal linamanqanaba onke amaprotheni kunye nezinto ezifunayo, kuba ufana naye. Kodwa-ke, ukungonakali kukuba ixhoba liyimpembelelo efanelekileyo kuyo nayiphi na i-pathogens okanye i-parasites ekwazi ukuhlala kwi-cannibal system. Ngaloo ndlela, ukunqandwa kwamanzi kungumonakalo obunobungozi, kuba ihamba nayo inokwenzeka kakhulu yokusuleleka kwizifo ezithile ukuba umntu uyondla abameli bezilwanyana. "

Idial Weapons

Ngenxa yoko, abaphandi bafuna ukufundisisa iimpawu ze-cannibalism phakathi kwezinambuzane ukuqonda ukuba kunceda okanye kuthintela ukusabalala kwezifo-ntsho. Ukuba igalelo kule nto, ke indlela yokukhusela izityalo iya kuba yinkqubela ngakumbi kunokuba izazinzulu zatsho njalo.
