Valul de c\u0103ldur\u0103 cu care se confrunt\u0103 Fran\u021ba afecteaz\u0103 majoritatea speciilor de animale s\u0103lbatice \u0219i le poate amenin\u021ba supravie\u021buirea, relateaz\u0103 AFP<\/a>.<\/p>\n

Un val de c\u0103ldur\u0103 \u201e<\/span>este brutal<\/span>\u201d pentru animale. Posibilit\u0103\u021bile de adaptare ale speciilor sau ecosistemelor \u201e<\/span>sunt mai mici dec\u00e2t \u00een \u200b\u200bcazul unei schimb\u0103ri graduale<\/span>\u201d, explic\u0103, pentru AFP, Gr\u00e9goire Lo\u00efs, ornitolog la Muzeul Na\u021bional de Istorie Natural\u0103 din Paris.<\/span><\/p>\n

Consecin\u021bele pot fi numeroase pentru fauna s\u0103lbatic\u0103. Ele includ deshidratare, stres termic, tulbur\u0103ri de reproducere, modific\u0103ri de comportament, dificult\u0103\u021bi de hr\u0103nire. \u00cen cele mai grave cazuri, pot duce inclusiv la moartea animalului, potrivit aceleia\u0219i surse.<\/p>\n

La \u00eenceputul verii anului 2021, <\/span>p\u00e2n\u0103 la 75% dintre speciile terestre \u0219i marine au fost<\/span> afectate negativ. Atunci, avut loc un val de c\u0103ldur\u0103 care a lovit vestul Americii de Nord. Popula\u021biile unor specii a sc\u0103zut 99%, a ar\u0103tat un studiu publicat \u00een martie.<\/span><\/p>\n

P\u0103s\u0103ri<\/h2>\n

P\u0103s\u0103rile sunt deosebit de amenin\u021bate de c\u0103ldur\u0103. \u00cen Fran\u021ba, din cele 20.000 de animale luate \u00een primire de centrele de \u00eengrijire anul trecut, 14,3% au fost <\/span>luate<\/span> ca urmare a circumstan\u021belor climatice (\u00een principal valuri de c\u0103ldur\u0103) \u0219i aproximativ 80% au fost p\u0103s\u0103ri, a declarat pentru AFP Anne-Laure Dugu\u00e9, \u0219efa programului \u201eFaun\u0103 s\u0103lbatic\u0103 \u00een pericol\u201d.<\/span><\/p>\n

Cu o temperatur\u0103 corporal\u0103 de 39 p\u00e2n\u0103 la 42\u00b0C, care cre\u0219te \u0219i mai mult \u00een timpul zborului sau al c\u0103ut\u0103rii de hran\u0103, p\u0103s\u0103rile au mai multe dificult\u0103\u021bi \u00een a-\u0219i disipa c\u0103ldura atunci c\u00e2nd temperaturile cresc, mai arat\u0103 sursa.<\/p>\n

P\u0103s\u0103rile nu au glandele sudoripare. Ele se r\u0103cesc \u00een principal prin evaporare pe calea respiratorie. Acest mecanism consum\u0103 mult\u0103 ap\u0103 \u0219i cre\u0219te riscurile de stres termic \u0219i deshidratare.<\/p>\n

Puii, \u00eenc\u0103 \u00een <\/span>cuib<\/span> \u0219i incapabili s\u0103 zboare \u00een timpul c\u0103ldurii sunt deosebit de vulnerabili.<\/span><\/p>\n

Mamifere<\/h2>\n

\u201e<\/span>La vertebrate, care \u00ee\u0219i regleaz\u0103 temperatura, r\u0103cirea mecanic\u0103 prin evaporare \u2013 g\u00e2f\u00e2itul, transpira\u021bia\u2026 \u2013 genereaz\u0103 o pierdere de ap\u0103 cu at\u00e2t mai mare cu c\u00e2t organismul este mai mic<\/span>\u201d, spune Lo\u00efs.<\/span><\/p>\n

\u201eRiscurile de hipertermie sau deshidratare sunt, prin urmare, deosebit de notabile la <\/span>arici \u0219i la unele <\/span>roz\u0103toare<\/span> mici\u201d , explic\u0103 Dugu\u00e9, potrivit sursei citate.<\/span><\/p>\n

Uneori se observ\u0103 mortalitate \u00een mas\u0103 a  <\/span>liliecilor. Ace\u0219tia sunt dezorienta\u021bi \u0219i deshidrata\u021bi de temperaturile extreme. \u00cen ianuarie 2026, mii de vulpi zbur\u0103toare (cei mai mari lilieci din lume) au pierit \u00een timpul unui val de c\u0103ldur\u0103 \u00een sud-estul Australiei.<\/span><\/p>\n

Mamiferele mari nu sunt nici ele cru\u021bate. La speciile adaptate la frig, cum ar fi <\/span>ur\u0219ii<\/span>, bizonii, <\/span>renii<\/span> sau elanii, blana deas\u0103 devine un handicap atunci c\u00e2nd termometrul cre\u0219te.<\/span><\/p>\n

Alte specii pot suferi arsuri la l\u0103bu\u021be, din cauza contactului cu suprafe\u021be supra\u00eenc\u0103lzite, cum ar fi bitumul sau nisipul, mai specific\u0103 sursa.<\/p>\n

Nevertebrate<\/h2>\n

Majoritatea nevertebratelor sunt ectoterme. Acest lucru \u00eenseamn\u0103 c\u0103 temperatura corpului lor depinde \u00een mare m\u0103sur\u0103 de mediul \u00eenconjur\u0103tor, explic\u0103 Lo\u00efs. Atunci c\u00e2nd limita lor de toleran\u021b\u0103 termic\u0103 este dep\u0103\u0219it\u0103, consecin\u021bele pot fi <\/span>\u201e<\/span>severe<\/span>\u201d<\/span>, avertizeaz\u0103 el.<\/span><\/p>\n

Abilitatea lor de a se deplasa este adesea limitat\u0103 sau chiar imposibil\u0103. \u00cen 2021, \u00een timpul valului de c\u0103ldur\u0103 din Pacificul de Nord, au pierit peste un miliard de midii, scoici \u0219i stele de mare, indic\u0103 sursa citat\u0103.<\/p>\n

Pe\u0219ti<\/h2>\n

La <\/span>pe\u0219ti<\/span>, temperaturile ridicate reduc oxigenul disponibil \u00een ap\u0103. \u00cen acela\u0219i timp, cresc nevoile lor fiziologice. Acest lucru poate provoca stres termic, boli, perturb\u0103ri ale reproducerii \u0219i uneori mortalit\u0103\u021bi \u00een mas\u0103.<\/span><\/p>\n

Amfibieni \u0219i reptile<\/h2>\n

Depinz\u00e2nd \u00een mare m\u0103sur\u0103 de umiditate, <\/span>broa\u0219tele, broa\u0219tele r\u00e2ioase<\/span> \u0219i salamandrele sunt deosebit de vulnerabile la valurile de c\u0103ldur\u0103. Ele sunt \u0219i mai afectate atunci c\u00e2nd acestea sunt \u00eenso\u021bite de secet\u0103, care le usuc\u0103 habitatele.<\/span><\/p>\n

Pielea lor permeabil\u0103 le face foarte susceptibile la deshidratare. \u00cen timpul valurilor de c\u0103ldur\u0103, pierd ap\u0103 mai u\u0219or \u0219i risc\u0103 s\u0103 se usuce dac\u0103 nu mai sunt \u00eendeplinite condi\u021biile de umiditate necesare supravie\u021buirii lor, arat\u0103 sursa.<\/p>\n

Reproducerea lor poate fi, de asemenea, grav afectat\u0103, \u00een special atunci c\u00e2nd zonele de depunere a icrelor se usuc\u0103 prematur.<\/p>\n","protected":false},"excerpt":{"rendered":"
