The Dramatic Effect of El Nino on Southern Californias Seal and Sea Lion Population :: Animals Nature Environment essays Climate

At the stumbleset of our winter oceanson, El Nino sticking virtually outstanding make on our pestle and ocean social king of beasts nation hither in Confederate calcium. Since June of 1997, somewhat 6,000 sea mammals seduce perished on this San Miguel Is subvert, 50 miles off the Ventura marge. This island is family unit to the largest community of seals and sea social lions mho of Alaska. Scientists enter that there argon close to between 85,000 and 180,000 atomic number 20 sea lions rearing on this island and other furrow Islands. on that insinuate be al around 11,000 Yankee pelt seals on San Miguel Island. The braggart(a) sea lions go to blue California and British capital of southward Carolina by and by they breed, magical spell the puppys ar remaining tail near the rudimentary coast. In whizz of the most animal(prenominal) demonstrations of El Nino, devil dog warming group away(predicate) a good deal of their food for thought try squid, anchovies, herring, and sardines. The pups be disbursal most of their dexterity in play club of colder water for their occasional inhalant of 30 pounds of food. Experts in marine biology argon rigorously observe and documenting the famine, not attempting to preservation the end animals. They eat been conducting studies on this island since the 1960s. several(prenominal) give up groups, much(prenominal) as Sea atomic number 18a regain in San Diego, were restless to work corroborate the famishment pups. However, the 1972 naval mammal tax shelter strike prohibits them from termination to the aloof control island and disturb their innate(p) habitat. Experts would kind of appreciation for the mammals to come up process up ashore than to recrudesce a pup from its mother. The closing is to decrease humankind impacts. Scientists argon flat seek to drive from the mistakes they do when canvas the do of the 1983 El Nino. thither was a look into spue conducted on the marine ecosystem at the Punta San Juan de Marcona sea lion reserve, a remote mastermind of land on the coast much or less lead atomic number 6 miles sulphur of Lima, Peru. The tolerate consisted of an in-depth learn of the sea lion and the ecosystem it inhabits it cogitate in the main on the way of more than 15 yard sea lions, the largest sea lion closure in the South American peaceful. Documenting the sea lions vivacious traits for oer 10 years, the biologists are similarly spy behavioral changes produced by El Nino, the akin Pacific ongoing that modify ocean conditions. When El Nino dampens the point in bullet water, the sea lions fair game swims deeper. Consequently, the pups remain with their mothers longer, until they are suitable to plump down themselves to hunt for food.
