Jul 8, 2024 · The Yellow Sea ecoregion (YSE) is internationally recognized as a global conservation priority due to its abundant natural resources. However, habitat destruction and loss severely threaten its biodiversity, resulting in its classification as an IUCN endangered ecosystem. The spotted seal (Phoca largha), a charismatic flagship species of the YSE, has received increasing conservation investment ...
Dec 18, 2023 · Canadian parliamentarians are warning that seal populations pose a danger to fish stocks and are upsetting marine ecosystems in the Pacific, Arctic and Atlantic oceans.
Oct 27, 2018 · Ecologists know that healthy predator populations in general, tend to promote greater biodiversity within an ecosystem (also an indicator of health) and healthier prey populations. In many cases, big populations of large-bodied animals like whales in the Gulf of Maine, or wildebeest in the African Savannah, have unintended benefits.

There are several species of ice-associated seals including bearded seals, ringed seals, spotted seals, ribbon seals, harp seals, and hooded seals. They are generally found in the Arctic, and depend on sea ice for at least part of the year to rest, breed, nurse and rear pups, molt, and avoid predators. However, the warming climate is changing the r...
Hawaiian monk seals are one of the most endangered seal species in the world and one of NOAA Fisheries’ Species in the Spotlight. They are found almost exclusively in the Hawaiian Archipelago. Hawaiian monk seals spend time on small low-lying islands to give birth, nurse their pups, and escape predators such as sharks. Climate change impacts includ...
Guadalupe fur seals live and breed on small rocky islands off southern California and the Pacific coast of Mexico. These areas are susceptible to warming waters, ocean acidification, and harmful algal blooms, all of which are increasing in frequency due to climate change. Guadalupe fur seals mostly eat squid and may be unable to adapt their diet to...
The effects of climate change on marine species and habitats will continue and increase in the coming decades. NOAA Fisheries is committed to our mission to conserve protected species in the face of these threats. With our partners, we have taken a series of steps to advance climate-focused science and management including: 1. Climate vulnerability...
Dec 17, 2020 · Diseases also kill seals, and can be natural or human-caused. For example, toxoplasmosis is the most lethal disease for monk seals, and is only present in Hawai ʻ i from the feces of cats. Researchers and managers therefore consider toxoplasmosis a human-caused threat because humans introduced domestic cats to the islands.

Mar 26, 2024 · Although often eclipsed in discussions of biodiversity loss by newer threats, such as habitat loss and climate change, overexploitation remains the strongest driver of population declines and extinctions globally (Ceballos et al., 2015; Maxwell et al., 2016). One common cause of the overharvesting of wildlife populations is over-estimation of the productivity of long-lived organisms; assuming ...
