Exploring the diversity of marine biomes, this overview delves into the classification of aquatic environments, the impact of human activities on natural landscapes, and the hidden world of microbial and endolithic biomes. It also addresses the significant shifts in global biomes due to climate change, emphasizing the need for conservation efforts.

Marine biomes are categorized into distinct zones, such as the littoral, pelagic, and abyssal zones, based on factors like depth and light availability
Four major categories: coastal, polar, trade wind, and westerly biomes
Pruvot's work in 1896 and Longhurst's refinement in 1998 resulted in the classification of marine biomes into four major categories based on unique climatic and oceanographic factors
Hydrothermal vents, cold seeps, benthic and pelagic zones, hadal zones, estuaries, coastal lagoons, kelp forests, and pack ice
Marine biomes also include specialized habitats, such as hydrothermal vents and kelp forests, which are influenced by factors like nutrient availability and temperature
Human activities, such as urbanization and agriculture, have significantly transformed the Earth's landscapes, giving rise to anthropogenic biomes
Urban areas, agricultural lands, managed forests, and indoor environments
Anthropogenic biomes include various types of ecosystems that have been significantly modified by human presence and land use practices, such as urban areas and managed forests
The concept of anthromes recognizes the extensive impact of human civilization on the biosphere and highlights the need for a revised framework to understand and manage terrestrial ecosystems
Microbial and endolithic biomes, which include organisms living within rocks and deep beneath the Earth's surface, reveal the extent of Earth's biodiversity
Nutrient cycling, soil formation, and atmospheric regulation
Microbial biomes play crucial roles in ecosystem functions, such as nutrient cycling and atmospheric regulation
The exploration of these biomes not only expands our understanding of Earth's biodiversity but also provides insights into the potential for life in extreme environments, including those on other planets
Climate change is causing shifts in the composition and distribution of global biomes, potentially leading to the formation of new biomes and the loss of existing ones
Arctic and mountainous regions, and forests in South America
Biomes in Arctic and mountainous regions, as well as forests in South America, are particularly at risk due to the effects of climate change on temperature and precipitation patterns
The critical need for global efforts to mitigate climate change is highlighted by the potential impacts on biomes and the diverse life they support
