A new study finds that 97.4 percent of marine species have less than 10 percent of their range represented in MPAs, with the US ranking near the bottom in terms of supporting formal protected areas. The research provides strategic guidance on where MPAs could be placed to better protect marine biodiversity.
A new study finds that more than 17,000 marine species worldwide remain largely unprotected. Nations like the US, Canada, and Brazil have large gaps in their protected areas, highlighting opportunities to achieve global biodiversity goals by 2020.
New research reveals that marine communities with a high thermal bias are more susceptible to ocean warming, leading to biodiversity changes. The study used data from the Reef Life Survey and found locations with average summer sea surface temperatures above 24°C to be the most vulnerable.
Reduced skeletal calcification in marine algae leads to impaired performance, threatening ecosystem balance. The study reveals a significant impact on material stiffness and flexibility, with even small changes causing substantial drops in ability to resist loads.
A new study by UC Santa Barbara researchers predicts that climate change will cause significant reshuffling of marine biodiversity, with warming oceans leading to the relocation of nearly 13,000 species. This redistribution is expected to increase biodiversity in many areas but also lead to extinctions and homogenization of communities.
A recent study models the impact of climate change on marine biodiversity, predicting that warming oceans will lead to significant changes in species distribution. The researchers found that some species will expand into new regions, while others with restricted ranges are likely to face extinction.
Scientists have revealed the Antarctic region is rich in species, with diverse ecosystems and micro-organismal life. The study highlights the need for comprehensive protection of the Ross Sea and improved conservation efforts to preserve this unique biodiversity.
A five-year project aims to combine species counts and ecological data with newer data gathered using satellites, robots, and genetic analyses. The Marine Biodiversity Observation Network (MBON) will classify habitats and sample each area effectively using regional maps and environmental DNA.
Researchers have discovered a high level of biodiversity in the 'Coral Triangle', a region in the central Indo-Pacific Ocean known for its coral reefs. At least nine previously unreported species of zoantharians were identified, highlighting the need for further exploration and analysis of marine life in this area.
A comprehensive marine biodiversity observation network could be established within 5 years with modest funding, addressing gaps in understanding global marine organism distribution under climate change threats. The network would help identify threats like exotic species invasions and resolve conflicts over ocean management.
A national marine biodiversity observation network is proposed to track ocean ecosystem health, monitor trends, and facilitate proactive responses to environmental pressures. The study recommends coordination of existing efforts, digitization of historical data, and establishment of regional centers to process and identify specimens.
Researchers at University of Guam identify new coral reef-associated alga, Rhipilia coppejansii, in Guam waters. The discovery highlights the island's underestimated marine algal diversity and its cultural significance.
Scientists link periodic extinctions and increased strontium-87 in marine fossils to a 60-million-year cycle of continental uplift. This process may have reduced sea depth, leading to habitat loss and decline in marine biodiversity.
A new study reveals that ancient global carbon, sulfur cycles, and sea-level changes drove the evolution of marine life over 500 million years. The research found a strong connection between these factors and marine biodiversity.
A new study reveals that small-scale fisheries in Peru are capturing tens of thousands of turtles from across the Pacific. The researchers found that thousands of sea turtles are likely to be caught annually while foraging in Peru's waters, often resulting in injuries from becoming tangled in fishing gear.
The deep open ocean is vastly under-explored due to the long-held belief that life in this area was confined primarily to the surface and near the sea bed. New research mapped marine species records and found most knowledge comes from shallow waters or ocean floor, revealing uncounted animals living without hard surfaces.
The Census of Marine Life has published an inventory of species distribution and diversity in 25 biologically representative regions around the world. Crustaceans comprise about one-fifth of all species found, with only two percent being vertebrates.
The Census of Marine Life has published a historic roll call of species in 25 biologically representative regions, revealing the most diverse marine ecosystems. The study found that Australian and Japanese waters are home to over 33,000 species, with mollusks and crustaceans making up half of all known species.
Scientists have identified over 6,000 unique species on the sea-floor, with many adapting to changing environmental conditions. Krill populations are reducing due to decreasing sea-ice cover, shifting the food web balance and affecting penguins that breed on the ice.
The First World Conference on Marine Biodiversity has reported a rapid northern migration of invasive marine species, spreading at 50 km per decade. This is significantly faster than terrestrial plants and may be due to the rapid dispersion of macroalgae propagules in the ocean.
Researchers will catalog and preserve diverse mollusk species in the Philippines, aiming to discover new products for central nervous system disorders, cancer, and antimicrobial drugs. The project also seeks to develop cellulosic biofuels production using enzymes from shipworms.
A study published in Science journal reveals the evolution of marine diversity over 50 million years, highlighting the Indo-Australian Archipelago as a tropical center of maximum diversity. The research provides new insights into biodiversity hotspots and their connection to environmental change.
A study finds that the loss of ocean species accelerates the collapse of entire ecosystems, reducing productivity and stability. The research projects the collapse of all currently fished seafoods by 2050, highlighting the need for sustainable management and biodiversity conservation.
A three-week expedition to French Frigate Shoals discovered many new species of crabs, corals, sea cucumbers, and other organisms. The expedition's findings provide a better understanding of marine biodiversity in the Hawaiian Archipelago.
The survey found a diverse range of life, including new fish species, in Malagasy waters. The region's coral diversity is one of the richest in the Indian Ocean, making it a high conservation priority.
The LIFOU 2000 survey discovered nearly 3000 species of mollusc living in a mere 5000 ha area on Lifou, outperforming the entire Mediterranean region. This staggering diversity includes many rare and unknown species, with some seen only once or represented by single examples.
The Global Biodiversity Information Facility (GBIF) will create a searchable database of species, facilitating the digitization and sharing of biodiversity data. This initiative addresses the lack of accessibility to biodiversity information in developing countries and aims to support scientific research and conservation efforts.
The Everglades' low biodiversity, caused by nutrient deficiencies, makes them vulnerable to pollution. Researchers recommend reducing agricultural runoff and filtering water through marshes to preserve the ecosystem's character.
A group of prominent scientists, including Harold Mooney and José Sarukhán, are launching the International Biodiversity Observation Year to address the urgent need for information about biodiversity. They propose short-term international projects to fill gaps in data and promote research on fundamental aspects of biodiversity.
