LOND\u00ddN – Siln\u00fd klimatick\u00fd jav El Ni\u00f1o by mohol v najbli\u017e\u0161\u00edch mesiacoch v\u00fdrazne ovplyvni\u0165 pohyb \u017eralokov.

Meteorol\u00f3govia o\u010dak\u00e1vaj\u00fa, \u017ee tohtoro\u010dn\u00fd Super El Ni\u00f1o v\u00fdrazne zohreje vody Tich\u00e9ho oce\u00e1nu. Vedci upozor\u0148uj\u00fa, \u017ee tento jav nemus\u00ed ovplyvvni\u0165 len po\u010dasie, ale aj spr\u00e1vanie morsk\u00fdch \u017eivo\u010d\u00edchov.

Na mo\u017en\u00e9 zmeny upozornili odborn\u00edci z Shark Lab pri California State University Long Beach, pod\u013ea ktor\u00fdch sa u\u017e teraz objavuj\u00fa mlad\u00e9 biele \u017eraloky pri pobre\u017e\u00ed sk\u00f4r ako po in\u00e9 roky. Informovali o tom viacer\u00e9 americk\u00e9 m\u00e9di\u00e1 s odvolan\u00edm na vedcov.<\/p>\n
Tepl\u00e1 voda men\u00ed migra\u010dn\u00e9 trasy<\/p>\n
Riadite\u013e v\u00fdskumn\u00e9ho centra Chris Lowe vysvet\u013euje, \u017ee teplej\u0161ia voda pri pobre\u017e\u00ed Kalifornie vytv\u00e1ra vhodnej\u0161ie podmienky pre mlad\u00e9 jedince \u017eraloka bieleho. Tie sa pres\u00favaj\u00fa zo severn\u00e9ho Mexika do plyt\u0161\u00edch v\u00f4d, kde maj\u00fa dostatok potravy.<\/p>\n

Viac \u017eralokov neznamen\u00e1 viac \u00fatokov<\/p>\n
Hoci spr\u00e1vy o vy\u0161\u0161om po\u010dte \u017eralokov m\u00f4\u017eu vyvol\u00e1va\u0165 obavy, odborn\u00edci zd\u00f4raz\u0148uj\u00fa, \u017ee to automaticky neznamen\u00e1 n\u00e1rast \u00fatokov na \u013eud\u00ed.<\/p>\n
V\u00fdskum Shark Lab ukazuje, \u017ee \u017eraloky dok\u00e1\u017eu \u010dloveka odl\u00ed\u0161i\u0165 od svojej prirodzenej koristi. V\u00e4\u010d\u0161ina jedincov sa po pribl\u00ed\u017een\u00ed jednoducho oto\u010d\u00ed a odpl\u00e1va. Chris Lowe dokonca uviedol, \u017ee po rokoch v\u00fdskumu nem\u00e1 obavy pl\u00e1va\u0165 vo vod\u00e1ch, kde sa tieto pred\u00e1tory pravidelne pohybuj\u00fa.<\/p>\n
Odborn\u00edci radia zachova\u0165 opatrnos\u0165<\/p>\n
Napriek tomu odborn\u00edci odpor\u00fa\u010daj\u00fa dodr\u017eiava\u0165 z\u00e1kladn\u00e9 bezpe\u010dnostn\u00e9 pravidl\u00e1. Plavci by sa mali vyh\u00fdba\u0165 vode za svitania a s\u00famraku, ke\u010f s\u00fa \u017eraloky najakt\u00edvnej\u0161ie. Rizikovej\u0161ie s\u00fa aj miesta v bl\u00edzkosti ryb\u00e1rskych lod\u00ed alebo kol\u00f3ni\u00ed tule\u0148ov, ktor\u00e9 predstavuj\u00fa prirodzen\u00fa koris\u0165 ve\u013ek\u00fdch pred\u00e1torov.<\/p>\n
\u00datoky zost\u00e1vaj\u00fa ve\u013emi zriedkav\u00e9<\/p>\n
Hoci sa v posledn\u00fdch rokoch po\u010det pozorovan\u00ed \u017eralokov pri americkom pobre\u017e\u00ed zv\u00fd\u0161il, \u00fatoky na \u013eud\u00ed s\u00fa st\u00e1le mimoriadne zriedkav\u00e9. V Kalifornii bolo od roku 1950 zaznamenan\u00fdch pribli\u017ene 250 incidentov, z ktor\u00fdch len mal\u00e1 \u010das\u0165 mala tragick\u00e9 n\u00e1sledky. Vedci preto zd\u00f4raz\u0148uj\u00fa, \u017ee pr\u00edtomnos\u0165 v\u00e4\u010d\u0161ieho po\u010dtu \u017eralokov je prirodzen\u00fdm d\u00f4sledkom zmien v morskom ekosyst\u00e9me, nie d\u00f4vodom na paniku.<\/p>\n
