Christopher Jones (Instituto FitzPatrick de Ornitolog\u00eda Africana<\/a><\/strong>(Universidad de Ciudad del Cabo, Sud\u00e1frica) y sus colegas publicaron en la revista Biolog\u00eda polar<\/em><\/a><\/strong> en 2019 sobre ratones dom\u00e9sticos introducidos Mus musculus<\/em> ataque a adultos de dos especies de albatros amenazados en la isla de Gough y a un petrel gigante del norte Macronectes halli<\/em> en la isla Marion.<\/p>\n

A continuaci\u00f3n figura el resumen de la breve nota:<\/strong><\/span><\/h4>\n

\u00abLos ratones dom\u00e9sticos invasores Mus musculus<\/em> son importantes depredadores de pollos de aves marinas en islas donde son el \u00fanico mam\u00edfero introducido, pero hay muy pocos registros de ataques a aves adultas. Presentamos las primeras pruebas de ataques de ratones a albatros y petreles adultos que cr\u00edan en las islas Marion y Gough, donde se ha producido recientemente un aumento de los ataques a pollos de aves marinas. En septiembre de 2017, se registraron heridas consistentes con un ataque de rat\u00f3n en un macho adulto incubador de petrel gigante del norte Macronectes halli<\/em> en la isla Marion. El nido estaba desierto, y el \u00e9xito reproductor en un radio de 500 m fue del 18% (n = 11) en comparaci\u00f3n con el 68% en los nidos de >a 500 m de distancia (n = 123), lo que sugiere que otros adultos incubando en las inmediaciones tambi\u00e9n podr\u00edan haberse visto afectados. En marzo de 2018, un albatros de Trist\u00e1n Diomedea dabbenena<\/em> en incubaci\u00f3n fue encontrado en la isla de Gough con una herida t\u00edpica de rat\u00f3n en la grupa. El huevo eclosion\u00f3 y m\u00e1s tarde se vio a la misma ave empollando y alimentando al polluelo. En octubre de 2018, se encontr\u00f3 en la isla de Gough un albatros atl\u00e1ntico de nariz amarilla Thalassarche chlororhynchos<\/em> en incubaci\u00f3n con una herida en la espalda que suger\u00eda el ataque de un rat\u00f3n y se hallaron 23 cad\u00e1veres recientes de esta especie, junto a nidos vac\u00edos, en colonias cercanas. Estas observaciones se suman a las pruebas cada vez m\u00e1s numerosas del impacto de los ratones en las aves marinas, y apoyan a\u00fan m\u00e1s los llamamientos para erradicar los ratones de las islas Marion y Gough\u00bb.<\/p>\n

\n POSTCRITO:<\/strong>
\n<\/span> En agosto de 2003 John Cooper observ\u00f3 un Petrel Gigante del Norte incubando en la Isla Marion con una gran herida en la grupa que dejaba al descubierto el hueso. Al d\u00eda siguiente, el ave no estaba presente y el huevo abandonado se rompi\u00f3. La lesi\u00f3n se debi\u00f3 posiblemente a un rat\u00f3n.<\/p>\n
