Parasite strain from cats killing sea otters

A newly developed timeline of early animal fossils suggests a relationship between sea level fluctuations, variations in marine oxygen, and the appearance of the earliest ancestors of present-day animals.

Global warming is causing sea levels to rise, which is altering ecosystems. Scientists assumed that the tidal wetlands present in estuaries could create less methane, a strong greenhouse gas because the increased influx of seawater renders these habitats less hospitable to methane-producing microorganisms.

In the scientific journal Nature Communications, a recent study headed by scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel offers the first insights into the stress response of a deep pelagic jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

In the chilly waters of the North Atlantic Ocean, scientists have long speculated that two kinds of sea stars—commonly known as starfish—found along the rocky coastlines of Europe and North America may have interbred. Hybrid starfish are already present and prospering along the coasts of New England and the Canadian Maritimes, according to freshly analysed genomic data.

Researchers have discovered the source of the Arctic Ocean's sea ice decline. The findings indicate that stronger declines in sea ice will occur when an atmospheric feature known as the Arctic dipole reverses itself in its recurring cycle.

Researchers have discovered the cause of the Arctic Ocean sea ice decrease since 2007. The results suggest that when an atmospheric phenomenon known as the Arctic dipole reverses itself in its periodic cycle, there will be more pronounced drops in sea ice.

Researchers have demonstrated that sinking fruit trees that have been cut down into the sea is an inexpensive and efficient approach to generating new reefs and increasing the variety and number of marine life in the area.

Microplastic waste can be discovered in the marine environment even at far-off places in the world. According to research led by Dr Barbara Scholz-Bottcher of the University of Oldenburg, these tiny particles originate on land but are also released back into the atmosphere by the sea.

Even in remote parts of the world, microplastic particles can be found in the marine environment. These tiny particles originate on land but are also re-emitted into the atmosphere by the sea, according to a study led by Dr Barbara Scholz-Böttcher of the University of Oldenburg.

Experts have warned that the categorization of domestic and wild cats will likely remain problematic for the foreseeable future, endangering current efforts to protect and restore native biodiversity.
