Regimbartia attenuata, minik bir Japon su b\u00f6ce\u011fi, s\u0131ra d\u0131\u015f\u0131 bir yetene\u011fe sahiptir: Kurba\u011falar\u0131n sindirim sisteminden ka\u00e7abilir, kurba\u011fan\u0131n an\u00fcs\u00fcnden canl\u0131 ve zarar g\u00f6rmemi\u015f bir \u015fekilde \u00e7\u0131kabilir. Bu dikkate de\u011fer ba\u015far\u0131, Kobe \u00dcniversitesi’nden ekolog Shinji Sugiura taraf\u0131ndan belgelenmi\u015ftir. Sugiura, R. attenuata ve kurba\u011falar aras\u0131ndaki av-avc\u0131 ili\u015fkisine dair kapsaml\u0131 bir ara\u015ft\u0131rma y\u00fcr\u00fctm\u00fc\u015ft\u00fcr.<\/p>\n\n
Bir kurba\u011fa taraf\u0131ndan yutuldu\u011funda, R. attenuata yakla\u015f\u0131k iki saat hareketsiz kal\u0131r. Ard\u0131ndan, bacaklar\u0131n\u0131 kullanarak kurba\u011fan\u0131n sindirim sisteminde aktif bir \u015fekilde ilerlemeye ba\u015flar. Bu hareket, kurba\u011fan\u0131n kloakal sfinkterini uyar\u0131r ve d\u0131\u015fk\u0131lamas\u0131na ve b\u00f6ce\u011fi d\u0131\u015far\u0131 atmas\u0131na neden olur. T\u00fcm ka\u00e7\u0131\u015f s\u00fcreci alt\u0131 dakikadan d\u00f6rt saate kadar s\u00fcrebilir.<\/p>\n\n
Sugiura, R. attenuata’n\u0131n bu ka\u00e7\u0131\u015f mekanizmas\u0131n\u0131, \u00e7ok \u00e7e\u015fitli b\u00f6cekleri t\u00fcketen obur avc\u0131lar olan kurba\u011falara kar\u015f\u0131 bir savunma olarak evrimle\u015ftirdi\u011fini \u00f6ne s\u00fcrmektedir. B\u00f6cek, kurba\u011fan\u0131n sindirim sisteminden ka\u00e7arak sindirilmekten ve \u00f6ld\u00fcr\u00fclmekten kurtulur.<\/p>\n\n
R. attenuata, ka\u00e7\u0131\u015f\u0131n\u0131 kolayla\u015ft\u0131ran birka\u00e7 fizyolojik uyarlamaya sahiptir. K\u00fc\u00e7\u00fck boyutu ve yanard\u00f6ner siyah rengi, kurba\u011fan\u0131n sindirim sisteminde kolayca gezinmesine olanak tan\u0131r. Ayr\u0131ca bacaklar\u0131, kurba\u011fan\u0131n ba\u011f\u0131rsak duvarlar\u0131na tutunmas\u0131na ve kendini ileri do\u011fru itmesine yard\u0131mc\u0131 olan minik t\u00fcylerle kapl\u0131d\u0131r.<\/p>\n\n
Sugiura’n\u0131n ara\u015ft\u0131rmas\u0131, R. attenuata’n\u0131n kurba\u011falardan ka\u00e7mada y\u00fcksek bir ba\u015far\u0131 oran\u0131na sahip oldu\u011funu g\u00f6stermi\u015ftir. Japonya’da yayg\u0131n bir kurba\u011fa t\u00fcr\u00fc olan Pelophylax nigromaculatus ile yap\u0131lan deneylerde, b\u00f6ceklerin %93’\u00fcnden fazlas\u0131 kurba\u011fan\u0131n an\u00fcs\u00fcnden ka\u00e7may\u0131 ba\u015fard\u0131. Benzer ba\u015far\u0131 oranlar\u0131 di\u011fer d\u00f6rt kurba\u011fa t\u00fcr\u00fcnde de g\u00f6zlemlendi.<\/p>\n\n
R. attenuata’n\u0131n kurba\u011falardan ka\u00e7ma yetene\u011fi, bu iki t\u00fcr aras\u0131ndaki avc\u0131-av dinamikleri \u00fczerinde potansiyel etkilere sahiptir. Kurba\u011falar, onun ka\u00e7\u0131\u015f yeteneklerinin fark\u0131ndaysa R. attenuata’y\u0131 t\u00fcketmekten ka\u00e7\u0131nabilirler. Alternatif olarak, kurba\u011falar b\u00f6ce\u011fi yemeye devam edebilir, ancak b\u00f6ce\u011fin ka\u00e7\u0131\u015f\u0131 nedeniyle ara s\u0131ra bir \u00f6\u011f\u00fcn kaybederler.<\/p>\n\n
R. attenuata, al\u0131\u015f\u0131lmad\u0131k ka\u00e7\u0131\u015f mekanizmalar\u0131na sahip tek b\u00f6cek t\u00fcr\u00fc de\u011fildir. \u00d6rne\u011fin, bombard\u0131man b\u00f6cekleri tehdit edildiklerinde avc\u0131lar\u0131 serbest b\u0131rakmaya zorlayan toksik bir kimyasal kokteyl p\u00fcsk\u00fcrtebilirler. Di\u011fer b\u00f6cekler, avc\u0131lar\u0131na ac\u0131 \u00e7ektirmek i\u00e7in \u00e7enelerini veya bacaklar\u0131n\u0131 kullanabilirler ve b\u00f6ce\u011fi t\u00fcketmelerini cayd\u0131r\u0131rlar.<\/p>\n\n
