"Sperm whales in the Southern Ocean are helping to reduce atmospheric carbon dioxide levels, rather than adding to them as marine mammals have been assumed to do.
Trish Lavery at Flinders University in Adelaide, Australia, and her co-workers calculated that the 12,000 or so sperm whales inhabiting the Southern Ocean facilitate the removal of 240,000 tonnes more carbon from the atmosphere per year than they add through respiration. The whales' iron-rich faeces fertilize iron-starved waters and stimulate the growth of phytoplankton. As these microscopic marine organisms sink to the ocean floor, it is thought that they take with them 20–40% of the carbon they have fixed through photosynthesis.
The authors say that other whale species may be having the same effect and warn that the hunting of sperm and other whales has probably decreased the removal of carbon from the atmosphere."

Al mismo tiempo, acaban de encontrar un fósil de ballena dentada super mega cool al que nombraron Leviathan, yeah man! ése sí que es un buen nombre para un género XD. Resulta que esta ballena tenía la mordida más grande eveeeer. También en Nature.
Pero pues, claro, somos unos ineptos con esto de manejar el planeta (incluyendo el país):
"In the open waters of the Gulf of Mexico, floating oil slicks and subsurface plumes threaten a highly diverse ecosystem. According to a 2009 inventory by the Harte Research Institute (HRI) for Gulf of Mexico Studies at Texas A&M University in Corpus Christi, the area around the ill-fated rig hosts 1,728 species, among them whale sharks, tarpon, tuna, sea turtles and sperm whales. With no end in sight for the spill, researchers are now struggling to understand the scope and nature of the damage to deep-ocean ecosystems through some of the Gulf's largest residents."

1)Si bueno y el humus??, siempre se olvidar al primer fijador de carbono. Además si la preocupación es cuidar el esperma de las ballenas para estrategias de conservación ¡bien!, aunque cuando nos vamos a preocupar por la variablidad de este.
2)Sigo creyendo que prefiero no comer ballena por que dada su pocentaje de grasa y por ende la capacidad de aucumular toxinas del gran bote de basura "mar".
3)¿Así son las citas formales con el index? Cool
se me olvidaba, el equivalente en numero de vacas es? XD
Pero me han dicho que sabe increible... =(
