La ce se refer\u0103 cuv\u00e2ntul \u201eamfibieni\u201d \u0219i cine sunt ace\u0219tia?<\/h2>\n\n\n\n

Cuv\u00e2ntul Amphibia <\/strong>\u00eenseamn\u0103 dou\u0103 vie\u021bi \u0219i se refer\u0103 la faptul c\u0103 amfibienii tr\u0103iesc \u00een dou\u0103 ecosisteme: cel acvatic \u0219i cel terestru. Aceasta reprezint\u0103 un grup biologic foarte vechi, ap\u0103rut acum 370 de milioane de ani. Animalele care fac parte din acest grup sunt semi-terestre \u0219i pe parcursul dezvolt\u0103rii lor exist\u0103 o faz\u0103 acvatic\u0103 \u00een care ace\u0219tia respir\u0103 prin branhii, trec\u00e2nd printr-un proces de schimbare sau metamorfoz\u0103 pentru a se adapta la procesul de a respira aer \u0219i a putea tr\u0103i \u0219i pe p\u0103m\u00e2nt. Acest proces prezint\u0103 forme \u0219i durate diferite, inclusiv exist\u0103 unii amfibieni care nu \u00eel fac complet, \u00eens\u0103 este cea mai important\u0103 caracteristic\u0103 a lor. Amfibienii sunt reprezenta\u021bi de broa\u0219te, tritoni, salamandre etc. \u00cen prezent, se cunosc circa 8445 specii de amfibieni, se descriu anual chiar \u0219i peste 100 de specii noi.<\/p>\n\n\n\n

De ce sunt importan\u021bi amfibienii?<\/h2>\n\n\n\n

Amfibienii sunt un bio-indicator al ecosistemelor. Putem m\u0103sura buna stare a unui ecosistem dup\u0103 num\u0103rul de amfibieni prezen\u021bi. Importan\u021ba lor este foarte mare, datorit\u0103 contribu\u021biei pe care o au ace\u0219tia \u00een lan\u021bul trofic. Pe de o parte, ei consum\u0103 un num\u0103r foarte mare de insecte, arahnide, reptile sau mamifere mici, pe de alt\u0103 parte, ace\u0219tia reprezint\u0103 o resurs\u0103 important\u0103 de hran\u0103 pentru p\u0103s\u0103ri, mamifere, pe\u0219ti etc. Prezen\u021ba lor este absolut necesar\u0103 pentru echilibrul ecosistemelor.<\/p>\n\n\n\n

Care este starea popula\u021biilor de amfibieni?<\/h2>\n\n\n\n

Din p\u0103cate, starea lor nu este nici de cum una bun\u0103. Peste 40% din speciile de amfibieni sunt \u00een risc de dispari\u021bie. Distrugerea \u0219i fragmentarea habitatelor, contamina\u021bia, speciile invazive, exploatarea necorespunz\u0103toare sau schimb\u0103rile climatice sunt unele dintre motive care au decimat aceste viet\u0103\u021bi \u0219i care pun \u00een pericol supravie\u021buirea lor. Datorit\u0103 naturii lor biologice \u0219i ecologice, aceste viet\u0103\u021bi sunt necesare pentru bun\u0103starea uman\u0103, \u00een sectoare importante, precum alimenta\u021bia sau s\u0103n\u0103tatea, dar nefiind singurele.<\/p>\n\n\n\n

Cu ce sunt de ajutor amfibienii?<\/h2>\n\n\n\n

Printre insectele consumate de c\u0103tre amfibieni, exist\u0103 unele care transmit boli \u0219i multe care sunt d\u0103un\u0103toare pentru agricultur\u0103. Amfibienii reu\u0219esc s\u0103 creeze un echilibru \u00een cadrul popula\u021biilor de insecte, astfel \u00eenc\u00e2t s\u0103 nu ajung\u0103 s\u0103 devin\u0103 prea periculoase pentru culturile noastre. De exemplu, o broasc\u0103 rugoas\u0103 (Bufo bufo<\/em>) poate s\u0103 m\u0103n\u00e2nce 100 de insecte pe zi.<\/p>\n\n\n\n

\u00cen ceea ce prive\u0219te medicina, \u00een amfibieni sunt prezente multe substan\u021be care se cerceteaz\u0103 cu interes. Exist\u0103 deja multe antibiotice \u0219i analgezice care sunt folosite \u00een tratamentul destinat oamenilor provenite din amfibieni. \u00cen pielea unor broa\u0219te s-au g\u0103sit analgezice de 200 de ori mai puternice dec\u00e2t morfina, compu\u0219i care amelioreaz\u0103 boala Alzheimer sau care sunt folosi\u021bi \u00een tratamentul diabetului de tipul 2.<\/p>\n\n\n\n

Unii amfibieni au capacitatea de a-\u0219i regenera extremit\u0103\u021bile t\u0103iate, ceea ce ofer\u0103 material de studiu despre regenerarea \u021besuturilor.<\/p>\n\n\n\n

Este suficient s\u0103 men\u021bion\u0103m \u0219i doar un singur aspect pentru a \u00een\u021belege care este importan\u021ba lor: 10% din toate premiile Nobel din istorie au fost ob\u021binute pe baza lucr\u0103rilor cu amfibieni.<\/p>\n\n\n\n

Amfibienii folosi\u021bi \u00een cercetare \u00een cadrul medicinii num\u0103r\u0103 un total de 100 de specii. A\u0219adar, toate speciile care exist\u0103 \u00eenc\u0103 pe planet\u0103 reprezint\u0103 un poten\u021bial enorm (\u0219i) \u00een acest domeniu. Din punct de vedere antropocentric, dispari\u021bia unei specii de amfibieni este echivalent\u0103 cu posibila pierdere a unei solu\u021bii la probleme prezente sau viitoare.<\/p>\n\n\n\n

Din toate punctele de vedere avem nevoie de amfibieni! \u0219i \u00eei pierdem! Ar trebui s\u0103 facem orice pentru a evita s\u0103 scad\u0103 \u0219i mai mult num\u0103rul popula\u021biilor acestora.<\/p>\n\n\n\n

\u00cen Rom\u00e2nia, situa\u021bia este grav\u0103, chiar dac\u0103 nu catastrofal\u0103 (\u00eenc\u0103), deoarece se mai p\u0103streaz\u0103 anumite areale semis\u0103lbatice \u00een care natura \u00ee\u0219i poate urma c\u00e2t de c\u00e2t cursul, dar pierdem oricum biodiversitatea la o vitez\u0103 foarte mare\u2026<\/p>\n","protected":false},"excerpt":{"rendered":"
