“Abstract: Although extinctions due to climate change are still uncommon, they might surpass those caused by habitat loss or overexploitation over the next few decades. Among marine megafauna, mammals fulfill key and irreplaceable ecological roles in the ocean, and the collapse of their populations may therefore have irreversible consequences for ecosystem functioning and services. Using a trait-based approach, we assessed the vulnerability of all marine mammals to global warming under high and low greenhouse gas emission scenarios for the middle and the end of the 21st century. We showed that the North Pacific Ocean, the Greenland Sea and the Barents Sea host the species that are most vulnerable to global warming. Future conservation plans should therefore focus on these regions, where there are long histories of overexploitation and there are high levels of current threats to marine mammals. Among the most vulnerable marine mammals were several threatened species, such as the North Pacific right whale (Eubalaena japonica) and the dugong (Dugong dugon), that displayed unique combinations of functional traits. Beyond species loss, we showed that the potential extinctions of the marine mammals that were most vulnerable to global warming might induce a disproportionate loss of functional diversity, which may have profound impacts on the future functioning of marine ecosystems worldwide.”

“Not long ago, fish of all kinds, including tuna, snapper and grouper, caught in coral reefs and mangrove forests of Pacific island nations like the Solomon Islands and East Timor filled the plates of local communities living near the sea. What they didn’t catch themselves, they bought from other local fishers—typically the small, less valuable fish. Served with a bit of rice and vegetables, these fish provided them with many of the minerals, micronutrients and protein they needed.”

“Let’s enjoy some unequivocal, inarguable good news: a paper published today in PNAS, Hilborn et al. 2020, shows that on average, scientifically-assessed fish populations around the world are healthy or improving. And, for fish populations that are not doing well, there is a clear roadmap to sustainability. With Australia on fire and scares of World War III, the start of 2020 and the new decade has been awful; hopefully Hilborn et al. 2020 can kickstart a decade of ocean optimism.”
“Have overfished fish populations been able to recover with better management? This is the question that an international group of researchers sought to answer by collating and analysing a database of 882 fish stocks, comprising nearly half of the world’s fish catch. They found that the abundance of fish has on average increased and that good management has led to healthy or improving fish abundance. The oceans are a vital source of food for many people across the globe. Fish – an important component of the world food system – account for about 20% of the animal protein and almost 7% of all protein eaten by humans. This number is even higher in some developing regions.”

“ABSTRACT: Marine protected areas (MPAs) are important for the preservation of ecosystem functioning, ecosystem services, resilience and biodiversity around the world. In South Africa, the role of MPAs in the protection of cetaceans is poorly understood, a knowledge gap that may affect management decisions and future cetacean conservation. Here, we used presence data of 9 odontocete species (namely southern bottlenose whale Hyperoodon planifrons, common dolphin Delphinus delphis, dusky dolphin Lagenorhynchus obscurus, false killer whale Pseudorca crassidens, Indo-Pacific humpback dolphin Sousa chinensis, Heaviside’s dolphin Cephalorhynchus heavisidii, killer whale Orcinus orca, Risso’s dolphin Grampus griseus and Indo-Pacific bottlenose dolphin Tursiops aduncus) to predict their distribution in the South African exclusive economic zone (EEZ) using ensemble models. The data were collected from various opportunistic, historical and scientific records spanning the period 1957-2014. Up to 9 predictor variables (sea surface temperature, chlorophyll a concentration, salinity, bathymetry, distance to shore, bottom slope, eastward and northward sea water velocity and bioregion) were used in the ensemble model to predict the distributions for each odontocete species. Model results suggest that some of the species’ preferred habitats are partially (i.e. <5% of the distribution) protected by the established MPAs, but the protection area does increase with the recently approved MPAs. This study provides a baseline for the distribution of the 9 odontocete species in relation to the MPAs, which could facilitate the protection and management of these species in the region and help identify important marine mammal areas.”

Outros 5,9% são atribuídos à pesca e aquacultura.
“Tonnes of fish caught through unsustainable fishing are being used by the fish meal and fish oil (FMFO) industries which supply feed to global aquaculture chains. These are wreaking havoc on fish stocks. The FMFO industry was considered a solace for fishermen as it purchased the trash fish (which is not edible) that came in with the catch. But the scenario has changed as the FMFO industries have now turned into a threat to the fisheries sector as the income from supplying to these industries is driving unsustainable fishing.”

“The greatest animal migration on Earth is likely something you never heard of and few have witnessed: legions of tiny marine creatures rising to the ocean surface every night to feed on tiny plants, then sinking back into the deep, dark water at dawn. Called the diel vertical migration, it was first recorded nearly 200 years ago by hauling ship nets through the water column. Today, marine scientists still sample the movement using shipboard nets. They also shoot acoustic signals into the water to track the sound “backscattering” off the zooplankton as they migrate up and down. Some collect data from aircraft, deploying a lidar system that uses a kind of laser radar to create the backscatter.”
