Ultraviolet radiation and aquatic bryophytes: physiological damage and protection mechanisms under laboratory and field conditions
La degradación de la capa de ozono estratosférico provoca un aumento de radiación ultravioleta-B (UV-B) en la Biosfera, lo que puede afectar a los organismos fotosintéticos. Dado que los briófitos de arroyos de montaña se han estudiado poco en este sentido, el objetivo de esta Tesis era profundizar …
