Aug 25, 2021 · August 25, 2021. A close relative of the manatee found in the Indo-Pacific, dugongs are a hit for tourists and an important part of coastal marine ecosystems. But between climate change, harmful ...
Nov 1, 2018 · We tracked 21 dugongs (Dugong dugon Müller 1776) using acoustic and satellite/GPS transmitters in 2012, 2013 and 2014 in Moreton Bay, Queensland at the high latitude limit of the species' winter range in eastern Australia to examine if there was a relationship between movements and environmental temperature that might suggest behavioural thermoregulation. Oceanic waters immediately outside ...

May 10, 2022 · Winter water temperatures in Florida already episodically drop below levels manatees can tolerate (Edwards 2013), resulting in cold stress and manatee mortality (Hardy et al. 2019). There are indications that polar vortices (areas of low pressure and cold air) may become less stable (weaken) under climate change (Simpson et al. 2018). As a ...

May 10, 2022 · Aerial survey and satellite tracking studies demonstrate that seasonal distribution patterns of dugongs within Shark Bay reflect changes in water temperature ; the animals seek out offshore waters warmed by the Indian Ocean when winter water temperatures in the bay fall below 18 °C (Holley et al. 2006), the dugongs’ apparent lower thermal threshold (Sheppard et al. 2006; Marsh et al. 2011).
inevitable leakage to dugong removal from these water bodies Climate change remains a major threat to marine species if one of the ones they will keep. According to the Great Barrier Reef Marine Park Authority’s study of the dugong’s movements and distribution. There are currently about 85 000 dugongs living in Australia, but this is declining.
Jan 4, 2019 · Both the manatees and dugongs have similar morphological and physiological limits on how they maintain a proper internal temperature, despite their varied habitats around the globe. A behavior which dugongs will exhibit to consciously demonstrate thermoregulation is to take a small migration to find warmer waters in the winter (Preen 2004).
8.2.1 Temperature Increases. The Intergovernmental Panel on Climate Change (IPPC 2019) reports that there is a 66–100% probability that the rate of ocean warming to depths of 700 m more than doubled between 1993 and 2017 from the 1969–1993 baseline. Ocean warming is greatest near the surface (IPPC 2014).
