….alebo ako sa znovu objavila Nasiternella regia<\/em> Riedel, 1914<\/h2>\n

 <\/p>\n

\u00a0Nasiternella regia<\/em> bola prv\u00fdkr\u00e1t n\u00e1jden\u00e1 a pop\u00edsan\u00e1 Riedelom za\u010diatkom 20. storo\u010dia, presne v\u00a0roku 1914, na z\u00e1kladne n\u00e1lezu z Rumunska. Od tohto obdobia sa na\u0161lo e\u0161te v\u00a0priebehu nieko\u013ek\u00fdch rokov p\u00e1r exempl\u00e1rov v\u00a0Alb\u00e1nsku a v Rak\u00fasku, av\u0161ak dokopy sa dal po\u010det n\u00e1jden\u00fdch exempl\u00e1rov tvoriacich celosvetov\u00fa zbierku druhu spo\u010d\u00edta\u0165 na prstoch jednej ruky. Od polovice 20. storo\u010dia sa po tomto najv\u00e4\u010d\u0161om druhu \u010de\u013eade Pediciidae akoby z\u013eahla zem…<\/p>\n

Ak sa prid\u0155\u017eame pravidiel Svetovej \u00fanie ochrany pr\u00edrody (IUCN): druh sa pova\u017euje za vyhynut\u00fd, ak nebol jeho \u017eiv\u00fd jedinec pozorovan\u00fd minim\u00e1lne 50 rokov<\/em>, by sme mohli tento druh pova\u017eova\u0165 za vyhynut\u00fd (EX z angl. extinct).<\/p>\n

No v\u010faka nov\u00fdm n\u00e1lezom tohto pozoruhodn\u00e9ho druhu zo Slovenska a\u00a0Rumunska vieme, \u017ee to tak nie je. Zauj\u00edmav\u00e9 je, \u017ee okrem toho, \u017ee druh existoval, sa o\u00a0\u0148om do dnes nevedelo prakticky ni\u010d. Nebola zn\u00e1ma larva a ani kukla, dokonca sa ani netu\u0161ilo kde by mohol \u017ei\u0165…<\/p>\n

Dnes u\u017e ale vieme pomerne dos\u0165 (viac info tu<\/a> a tu<\/a>), no z\u010faleka nie v\u0161etko. Nasiternella regia<\/em> je po\u010das svojho \u017eivota \u00fazko sp\u00e4t\u00e1 s dendrotelmami, \u010di\u017ee so zavodnen\u00fdmi dutinami v\u00a0stromoch, spravidla v such\u0161\u00edch a\u00a0teplej\u0161\u00edch oblastiach. Larvy predstavuj\u00fa doposia\u013e nezn\u00e1meho „top“ pred\u00e1tora ekosyst\u00e9mov dendroteliem. Rovnako sa v\u00a0dendrotelm\u00e1ch aj kukl\u00ed a\u00a0jej dospelce tr\u00e1via v\u00e4\u010d\u0161inu svojho \u017eivota rovnako v\u00a0t\u00fdchto ekosyst\u00e9moch. Bahniarka dendrotelmov\u00e1 je pravdepodobne akt\u00edvna mimo d\u0148a. Aj ke\u010f je pomerne ve\u013ek\u00e1 a\u00a0m\u00e1 teda aj patri\u010dne ve\u013ek\u00e9 kr\u00eddla (a\u017e 2,5 cm dlh\u00e9), je ve\u013emi zl\u00fd letec. Dodnes nie je jasn\u00e9 ako si vyh\u013ead\u00e1va partnera a\u00a0nov\u00e9 biotopy – dendrotelmy, preto\u017ee bola takmer v\u017edy pozorovan\u00e1 iba pri ch\u00f4dzi a\u00a0nie pri lete.<\/p>\n

Keby sme si to mali zhrn\u00fa\u0165….<\/p>\n

\u00a0Z\u00a0cel\u00e9ho sveta je zn\u00e1mych len nieko\u013eko jedincov tohto druhu, ktor\u00e9 sa daj\u00fa spo\u010d\u00edta\u0165 na prstoch troch r\u00fak. Najv\u00e4\u010d\u0161ia \u017eiv\u00e1 popul\u00e1cia tohto druhu je moment\u00e1lne zn\u00e1ma len zo Slovenska (plus n\u00e1hodne odchyten\u00fd exempl\u00e1r je publikovan\u00fd aj z\u00a0Rumunska).

Av\u0161ak v\u010faka svojmu tajupln\u00e9mu \u017eivotu unik\u00e1 na\u0161ej pozornosti. Rovnako aj v\u010faka tejto bahniarke by sme mali omnoho viac dba\u0165 na to, aby v\u00a0na\u0161ich lesoch zost\u00e1vali aj star\u00e9 stromy, ktor\u00e9 s\u00fa vhodn\u00fdm biotopom pre mnoh\u00e9 cenn\u00e9,\u00a0vz\u00e1cne a\u00a0ohrozen\u00e9 druhy.<\/p>\n
