Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, which is invisibly small to the unaided human eye without magnification ...
Marine invertebrates are susceptible to viral diseases. [60] [61] [62] Sea star wasting disease is a disease of starfish and several other echinoderms that appears sporadically, causing mass mortality of those affected. [63] There are around 40 different species of sea stars that have been affected by this disease.
Mosquito-borne diseases that are sensitive to climate include malaria, lymphatic filariasis, Rift Valley fever, yellow fever, dengue fever, Zika virus, and chikungunya. [6] [7] [8] Scientists found in 2022 that rising temperatures are increasing the areas where dengue fever, malaria and other mosquito-carried diseases are able to spread.
Ocean surface habitats sit at the interface between the atmosphere and the ocean. The biofilm-like habitat at the surface of the ocean harbours surface-dwelling microorganisms, commonly referred to as neuston. This vast air–water interface sits at the intersection of major air–water exchange processes spanning more than 70% of the global ...
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
A study of the ochre sea star (Pisaster ochraceus) populations from San Diego, California, to southern British Columbia, along with at two locations near Sitka, Alaska, found that population declines were proportionately greater for sea stars in the southern part of the coast than the north; [6] population numbers are usually higher at more ...
A 2022 statement from the World Health Organization (WHO), defines the term this way: “Disease X is [used] to indicate an unknown pathogen that could cause a serious international epidemic.”
In 1998, coral reefs experienced the most severe mass bleaching events on record, when vast expanses of reefs across the world died because sea surface temperatures rose well above normal. [ 57 ] [ 58 ] Some reefs are recovering, but scientists say that between 50% and 70% of the world's coral reefs are now endangered and predict that global ...
