Christa Beckmannov\u00e1, ekologi\u010dka divok\u00e9 zv\u011b\u0159e z RMIT University v Austr\u00e1lii, si tohoto trendu poprv\u00e9 v\u0161imla p\u0159i studiu stravovac\u00edch n\u00e1vyk\u016f dravc\u016f. Sb\u00edrala mrtv\u00e9 \u017e\u00e1by z d\u00e1lnic, aby pozorovala, jak\u00e9 druhy pt\u00e1ci preferuj\u00ed, a v\u0161\u00edmala si stop zanechan\u00fdch v t\u00e1cc\u00edch s p\u00edskem um\u00edst\u011bn\u00fdm bl\u00edzko mrtvol. Jej\u00ed zv\u011bdavost vedla k ned\u00e1vn\u00e9mu p\u0159ehledu literatury, kter\u00fd na\u0161el v\u00edce ne\u017e 300 studi\u00ed, kter\u00e9 pou\u017e\u00edvaly zab\u00edjen\u00ed silnic, od z\u00e1kladn\u00edch inventur druh\u016f a\u017e po p\u0159evratn\u00e9 objevy. <\/p>\n

Tato praxe nen\u00ed nov\u00e1, ale jej\u00ed p\u0159ijet\u00ed jako legitimn\u00ed v\u011bdeck\u00e9 metody roste. V\u00fdzkumn\u00edci zji\u0161\u0165uj\u00ed, \u017ee roadkill m\u016f\u017ee poskytnout vhled do anatomie zv\u00ed\u0159at, prevalence nemoc\u00ed a distribuce invazn\u00edch druh\u016f \u2013 dokonce vede k identifikaci zcela nov\u00fdch druh\u016f, jako je cecilian v Braz\u00edlii a hlodavec v Indii. <\/p>\n

Etick\u00fd sb\u011br vzork\u016f pro v\u011bdeck\u00fd v\u00fdzkum<\/h3>\n

Kl\u00ed\u010dov\u00fdm argumentem pro pou\u017e\u00edv\u00e1n\u00ed roadkill je jeho etick\u00e1 v\u00fdhoda oproti tradi\u010dn\u00edm metod\u00e1m. V\u00fdzkumn\u00edci jsou pod rostouc\u00edm tlakem, aby minimalizovali \u0161kody na \u017eiv\u00fdch zv\u00ed\u0159atech, a zab\u00edjen\u00ed na cest\u00e1ch nab\u00edz\u00ed zp\u016fsob, jak z\u00edskat tk\u00e1n\u011b a vzorky bez odchytu nebo eutanazie voln\u011b \u017eij\u00edc\u00edch \u017eivo\u010dich\u016f. Jak \u0159\u00edk\u00e1 Beckmann, \u201e[Road Dead] je fantastick\u00fdm etick\u00fdm zdrojem vzork\u016f.<\/p>\n

Tento p\u0159\u00edstup se hod\u00ed k \u0161ir\u0161\u00edmu hnut\u00ed za \u00fa\u010delem sn\u00ed\u017een\u00ed pou\u017e\u00edv\u00e1n\u00ed zv\u00ed\u0159at ve v\u00fdzkumu a nahrazov\u00e1n\u00ed \u017eiv\u00fdch exempl\u00e1\u0159\u016f, kdykoli je to mo\u017en\u00e9. I kdy\u017e to nen\u00ed ide\u00e1ln\u00ed, pou\u017eit\u00ed ji\u017e mrtv\u00fdch zv\u00ed\u0159at je v mnoha p\u0159\u00edpadech zodpov\u011bdn\u011bj\u0161\u00ed alternativou.<\/p>\n

Celkov\u00fd obraz: Silnice jako ekologick\u00e9 pasti<\/h3>\n

P\u0159evl\u00e1daj\u00edc\u00ed vztek na silnic\u00edch podtrhuje chmurn\u011bj\u0161\u00ed realitu: silnice samy o sob\u011b jsou past\u00ed \u017eivotn\u00edho prost\u0159ed\u00ed. Studie z roku 2016 zjistila, \u017ee 20 % glob\u00e1ln\u00ed plochy se nach\u00e1z\u00ed do jednoho kilometru od silnice a toto \u010d\u00edslo roste. Fraser Schilling, \u0159editel Centra pro silni\u010dn\u00ed ekologii na Kalifornsk\u00e9 univerzit\u011b v Davisu, bez obalu popisuje silnice jako \u201emasivn\u00ed s\u00edt\u011b, v podstat\u011b gilotiny\u201c. <\/p>\n

Na silnic\u00edch ro\u010dn\u011b um\u00edraj\u00ed miliony zv\u00ed\u0159at, ale tyto \u0161kody lze vyu\u017e\u00edt pro v\u011bdeck\u00e9 \u00fa\u010dely. Schilling zd\u016fraz\u0148uje, \u017ee odb\u011br vzork\u016f u silnice by se m\u011bl pou\u017e\u00edvat pouze v p\u0159\u00edpad\u011b, \u017ee nahrazuje potenci\u00e1ln\u011b \u0161kodliv\u00e9 metody odb\u011bru vzork\u016f. Hlavn\u00ed c\u00edl z\u016fst\u00e1v\u00e1 stejn\u00fd: v prvn\u00ed \u0159ad\u011b zabr\u00e1nit t\u011bmto \u00famrt\u00edm. <\/p>\n

Hodnota mrtv\u00fdch na silnic\u00edch jako v\u011bdeck\u00e9ho zdroje zd\u016fraz\u0148uje paradox: zat\u00edmco silnice p\u0159edstavuj\u00ed v\u00e1\u017enou hrozbu pro divokou zv\u011b\u0159, v\u00fdsledn\u00e1 smrt m\u016f\u017ee p\u0159isp\u011bt k na\u0161emu \u00fasil\u00ed o porozum\u011bn\u00ed a ochranu. V\u00fdzkumn\u00edci doufaj\u00ed, \u017ee maximalizac\u00ed p\u0159\u00ednos\u016f t\u011bchto nevyhnuteln\u00fdch \u00famrt\u00ed mohou ospravedlnit ponurou realitu a podporovat eti\u010dt\u011bj\u0161\u00ed v\u00fdzkumn\u00e9 postupy.<\/p>\n","protected":false},"excerpt":{"rendered":"
