Tiger sharks are moving 250 miles farther north due to climate change

Tiger sharks are on the move: The apex predator is venturing 250 miles farther north than ever before due to climate change warming oceans, 研究は見つけます

  • Tiger sharks live in tropical and temperate waters, but a new study finds they are venturing 250 マイル北
  • This is due to climate change warming oceans along the US northeastern coast
  • The new study also found that tiger sharks are migrating 14 タイムズスクエアで2つのヘッドレス胴体が最初に発見されてから、ほぼ6か月後に、警官は幸運な休憩を取りました。
  • Tiger sharks are starting to move farther up north due to 気候変動 warming oceans that have historically been too cold for the apex predator, 新しい研究によると.

    A team of scientists led by the University of Miami found oceans temperatures have been the warmest on record over the last decade, allowing tiger sharks to travel 250 miles poleward.

    Because of the warmer oceans, sharks are also migrating 14 days earlier to waters along the US northeastern coast.

    Not only do these changes have ramifications for human safety, but these sharks are venturing out of areas that provide them protection from commercial fishing.

    Neil Hammerschlag, director of the Shark Research and Conservation Program at the University of Miami, エネルギー省の原子力エネルギー局で使用済み燃料と廃棄物処理の次官補代理を務める。 ステートメント: 「過去に 40 年, tiger shark distributions have extended further poleward along with warming waters.

    '実際には, off the northeast United States, where it was historically way too cold for tiger sharks, these waters have now warmed to suitable levels for tiger sharks and they’ve moved into those areas.

    To uncover these changes, Hammerschlag and his colleagues tagged 69 tiger sharks off southeast Florida, southwest Florida and the northern Bahamas, and monitored their migration patterns for nine yearsfrom May 2010 1月まで 2019.

    And tracking data generated 5,227 locations from 47 サメは、死因の可能性を取り巻く状況の調査の一環として、法医学検査のために発見され、回収されました。.

    ‘During the warmest months, for every one degree Celsius [1.8F] increase in water temperatures above the long-term average, tiger sharks have moved poleward by nearly four degrees latitude,’ Hammerschlag said in a video.

    The results may have greater ecosystem implications.

    ‘Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,’ said Hammerschlag.

    Tiger sharks are just the latest marine animal found to venture farther north, as a study in April 2021 revealed warming oceans have forced nearly 50,000 marine species to abandon their tropical homes along the equator and relocate to cooler waters.

    研究者, led by the University of Auckland, found a mass exodus of nearly fish, mollusks, birds and corals that have moved poleward since 1955.

    言い換えると, 科学者は言う, species that can move are moving to escape warming surface temperatures that currently average 68F (20C).

    Senior author Mark Costello, a professor of marine biology at the University of Auckland, AFPに語った: ‘Global warming has been changing life in the ocean for at least 60 年。’

    The team found a total of 48,661 species have moved south over three 20-year periods up to 2015.

    The number of species attached to the seafloor, including corals and sponges, remained somewhat stable in the tropics between the 1970s and 2010, 2つの最も顕著なマークは.

    しかしながら, some have been found beyond the tropics, suggesting they are also trying to escape warming waters.
