Comportamentul de acest gen, care este des \u00eent\u00e2lnit la oameni, este valabil \u0219i-n lumea micilor, dar \u0219i marilor mamifere, potrivit Revistei Smithstonian.<\/a><\/p>\n

Uneori, c\u00e2nd oamenii petrec suficient de mult timp \u00eempreun\u0103, \u00eencep s\u0103 foloseasc\u0103 acela\u0219i argou, acelea\u0219i inflexiuni vocale \u0219i acela\u0219i ton. Oamenii tind s\u0103 repete expresiile celor din jur, \u00een special ale oamenilor cu care au rela\u021bii personale str\u00e2nse. Acest timp de comportament se nume\u0219te convergen\u021b\u0103 vocal\u0103.<\/p>\n

Nu doar oamenii adopt\u0103 acest comportament, ci \u0219i necuv\u00e2nt\u0103toarele. De exemplu, delfinii cu bot gros care au rela\u021bii sociale str\u00e2nse, precum mamele \u0219i puii lor, care \u00ee\u0219i imit\u0103 reciproc vocalizele. Elefan\u021bii din acelea\u0219i grupuri sociale scot, de asemenea, sunete similare.<\/p>\n

\u0218i liliecii, \u00een general, adopt\u0103 acest timp de comportament, iar un studiu publicat, anul trecut, \u00een revista \u201eProceedings of the Royal Society B\u201d<\/a> <\/span>arat\u0103 c\u0103 \u0219i liliecii-vampir scot sunete mai similare pe m\u0103sur\u0103 ce se \u00eemprietenesc sau dezvolt\u0103 rela\u021bii str\u00e2nse al\u0103turi de al\u021bii la fel ca ei.<\/p>\n

\u201eComunicarea vocal\u0103 la lilieci este un aspect despre care nu \u0219tim prea multe\u201d<\/em>, spune ecologul comportamental care a condus studiul, Gerald G. Carter.<\/p>\n

\u201eDar \u0219tim c\u0103 vedem doar v\u00e2rful aisbergului, deoarece liliecii, \u00een general, au o complexitate vocal\u0103 uimitoare\u201d<\/em>, a declarat cercet\u0103torul ce activeaz\u0103 \u00een cadrul Universit\u0103\u021bii Princeton, al Institutului Medical Howard Hughes \u0219i al Institutului Smithsonian de Cercet\u0103ri Tropicale.<\/p>\n

<\/h2>\n

Cum \u00eei ajut\u0103 pe lilieci sunetele emise?<\/h2>\n

Liliecii-vampir folosesc aceast\u0103 complexitate vocal\u0103 pentru a v\u00e2na \u0219i a se hr\u0103ni \u00een fiecare noapte. \u00cen cadrul studiului, cercet\u0103torii au ad\u0103postit \u00eempreun\u0103 95 de lilieci-vampir comuni (Desmodus rotundus) care provin din zone diferite<\/p>\n

Timp de nou\u0103 ani, din 2011 p\u00e2n\u0103 \u00een 2019, exper\u021bii au analizat aproape 700.000 de tipuri de vocaliza\u021bii, adic\u0103 tipuri de sunete de \u00eenalt\u0103 frecven\u021b\u0103 specifice acestor mici necuv\u00e2nt\u0103toare. Pentru fiecare tip de sunet au studiat c\u00e2te 35 de caracteristici acustice, iar savan\u021bii au ajuns la concluzia c\u0103 sunetele scoase de ace\u0219tia au \u00eenceput s\u0103 semene pe m\u0103sur\u0103 ce \u201ese \u00eemprieteneau\u201d.<\/p>\n

Ei se \u00eemprietenesc \u00eemp\u0103r\u021bind hrana<\/h2>\n

Cu toate acestea, simpla al\u0103turare a lor nu este suficient\u0103. Pentru a se \u00eemprieteni cu adev\u0103rat, ei trebuie s\u0103-\u0219i \u00eempart\u0103 hrana. Potrivit studiului, cu c\u00e2t \u00eemp\u0103r\u021beau mai mult\u0103 hran\u0103, cu at\u00e2t liliecii-vampir deveneau mai apropia\u021bi, iar sunetele lor se asem\u0103nau tot mai mult. Pentru aceste mici mamifere, hrana este str\u00e2ns legat\u0103 de supravie\u021buire.<\/p>\n

Vampire bat!! Desmodus rotundus showed up last night in the farm where we were netting. Such a cool creepy behavior\ud83e\ude78\ud83e\udd87 pic.twitter.com\/QKilS4EhT3<\/a><\/p>\n

Ba mai mult, liliecii-vampir care se \u00eemprietenesc unii cu ceilal\u021bi ajung s\u0103 foloseasc\u0103, ceea ce savan\u021bii numesc \u201eapeluri de contact\u201d, adic\u0103 sunete scoase de cei care sunt singuri. Acest tip de vocaliza\u021bii \u00eei ajut\u0103 s\u0103 recunoasc\u0103 \u0219i s\u0103 ia leg\u0103tura cu \u201eprietenii lor\u201d.<\/p>\n

Liliecii-vampir se pot deplasa \u0219i la sol<\/h2>\n

Liliecii-vampir tr\u0103iesc \u00een regiunile tropicale \u0219i subtropicale ale Americii Latine, \u00een America Central\u0103, dar \u0219i Mexic. Spre deosebire de liliecii obi\u0219nui\u021bi \u00eent\u00e2lni\u021bi \u00een Europa \u2013 care se hr\u0103nesc, \u00een principal cu insecte \u0219i sunt v\u00e2n\u0103tori aerieni \u2013 liliacul-vampir se poate deplasa \u0219i la sol.<\/p>\n

Acesta poate merge, alerga \u0219i chiar s\u0103ri pentru a-\u0219i surprinde prada. El se hr\u0103ne\u0219te exclusiv cu s\u00e2ngele mamiferelor. Liliacul-vampir m\u0103soar\u0103 \u00eentre 7 \u0219i 9 centimetri, \u0219i are o anvergur\u0103 a aripilor de 35, p\u00e2n\u0103 la 40 de centimetri. Are col\u021bi ascu\u021bi\u021bi. Atunci c\u00e2nd se hr\u0103ne\u0219te, el face o mic\u0103 incizie \u0219i linge s\u00e2ngele care curge. Saliva sa con\u021bine un anticoagulant care \u00eei permite s\u0103 continue s\u0103 se hr\u0103neasc\u0103.<\/p>\n

Spre deosebire de semenii lor europeni, liliecii-vampir au \u0219i termo-detec\u021bie. Ace\u0219tia \u00ee\u0219i pot identifica prada \u00een func\u021bie de temperatura corpului, \u00eens\u0103 sunt capabili s\u0103 foloseasc\u0103 \u0219i ecoloca\u021bia. Adic\u0103 emit ultrasonice de \u00eenalt\u0103 frecven\u021b\u0103 care se reflect\u0103 de corpurile \u00eent\u00e2lnite \u0219i se \u00eentorc la ace\u0219tia, oferindu-le o hart\u0103 detaliat\u0103 a \u00eemprejurimilor.<\/p>\n","protected":false},"excerpt":{"rendered":"
