Tropical reef fish, 81, is the oldest ever discovered by scientists

The octogenarian fish, which is old enough to have lived through World War II, was found by the Australian Institute of Marine Science at the Rowley Shoals, about 300 kilometers (186 miles) west of Broome, as part of a study into the longevity of tropical fish.

Researchers looked at three species they said were not commonly targeted by commercial or recreational fishing in Western Australia and the Chagos Archipelago in the central Indian Ocean. The species included red bass, midnight snapper and black and white snapper.

The 81-year-old midnight snapper was identified alongside 10 other fish over the age of 60, including a 79-year-old red bass that was also caught in the Rowley Shoals — an area spanning three coral reefs at the edge of Australia’s continental shelf.

Marine scientists determined the age of the fish by dissecting them and studying their ear bones, or otoliths, which contain annual growth

Octogenarian snapper found off Australia becomes oldest tropical reef fish by two decades — ScienceDaily

An 81-year-old midnight snapper caught off the coast of Western Australia has taken the title of the oldest tropical reef fish recorded anywhere in the world.

The octogenarian fish was found at the Rowley Shoals — about 300km west of Broome — and was part of a study that has revised what we know about the longevity of tropical fish.

The research identified 11 individual fish that were more than 60 years old, including a 79-year-old red bass also caught at the Rowley Shoals.

Australian Institute of Marine Science (AIMS) Fish Biologist Dr Brett Taylor, who led the study, said the midnight snapper beat the previous record holder by two decades.

“Until now, the oldest fish that we’ve found in shallow, tropical waters have been around 60 years old,” he said.

“We’ve identified two different species here that are becoming octogenarians, and probably older.”

Dr Taylor said the research will

New Study Finds These Tropical Fish Can Live To Be Over 80 Years Old

How long do fish live? 10 years? Twenty? Try over 80 years, according to new research on snappers.

Before now, the oldest known snapper was recorded at 60 years old, two decades younger than findings recently published in the journal Coral Reefs. Does this twenty-year age gap matter? According to fisheries scientist and the study’s lead author Dr. Brett Taylor, it matters quite a bit.

Snappers serve as an important food source around the world. Despite the snapper’s importance, the global snapper fishery is, in large part, poorly managed. This, combined with the high market value of some snapper species, led the U.S. National Oceanic and Atmospheric Administration (NOAA) to officially label red snapper as ‘at risk’ for illegal, unreported, and unregulated (IUU) fishing and market fraud in 2015.

Community conservation reserves protect fish diversity in tropical rivers — ScienceDaily

Prohibiting fishing in conservation reserves is a common strategy for protecting ocean ecosystems and enhancing fisheries management. However, such dedicated reserves are rare in freshwater ecosystems, where conservation efforts generally piggyback on the protection of terrestrial habitats and species.

Now, a collaboration between researchers from Cornell University and the University of Wisconsin-Madison has found that small, community-based reserves in Thailand’s Salween River Basin are serving as critical refuges for fish diversity in a region whose subsistence fisheries have suffered from decades of overharvesting.

The team’s paper, “A Network of Grassroots Reserves Protects Tropical River Fish Diversity,” published Nov. 25 in Nature.

The lead author is Aaron Koning, a former postdoctoral fellow with the Cornell Atkinson Center for Sustainability who is currently a postdoctoral researcher at the University of Nevada, Reno. The project was overseen by Pete McIntyre, the Dwight Webster Sesquicentennial Faculty Fellow and associate professor of natural resources

Some tropical forests show surprising resilience as temperatures rise

The world’s hottest rainforest is located not in the Amazon or anywhere else you might expect, but inside Biosphere 2, the experimental scientific research facility in the desert outside Tucson, Arizona. A recent study of tropical trees planted there in the early 1990s reported a surprising result: They have withstood temperatures higher than any likely to be experienced by tropical forests this century.

The study adds to a growing tally of findings that are giving forest scientists something that’s been in short supply lately: hope. Plants may have unexpected resources that could help them survive—and perhaps even thrive—in a hotter, more carbon-rich future. And while tropical forests still face both human and natural threats, some researchers believe dire reports of their impending decline due to climate change may have been exaggerated.

“Biology is ingenious,” says Scott Saleska, an ecologist at the University of Arizona in Tucson and co-leader of the

Tropical peatland conservation could protect humans from new diseases — ScienceDaily

Conservation of tropical peatlands could reduce the impacts of the COVID-19 pandemic and the likelihood of new diseases jumping from animals to humans, researchers say.

The scientists reviewed existing evidence and concluded the high biodiversity in tropical peat-swamp forests, combined with habitat destruction and wildlife harvesting, created “suitable conditions” for emerging infectious diseases (EIDs) that could jump to humans.

COVID-19 did not emerge in a tropical peatland area — but HIV/AIDS and the joint-first case of Ebola both originated in areas with extensive peatlands.

The study also assessed the possible impact of COVID-19 on tropical peatland conservation and local communities — and identified “numerous potential threats” to both.

Led by the University of Exeter, the international study team comprised researchers from countries with large tropical peatlands, including Indonesia, DR Congo and Perú.

“We’re not saying tropical peatlands are unique in this respect — but they are one important habitat where

Study reconstructs ancient storms to help predict changes in tropical cyclone hotspot — ScienceDaily

Intense tropical cyclones are expected to become more frequent as climate change increases temperatures in the Pacific Ocean. But not every area will experience storms of the same magnitude. New research from the Woods Hole Oceanographic Institution (WHOI) published in Nature Geoscience reveals that tropical cyclones were actually more frequent in the southern Marshall Islands during the Little Ice Age, when temperatures in the Northern Hemisphere were cooler than they are today.

This means that changes in atmospheric circulation, driven by differential ocean warming, heavily influence the location and intensity of tropical cyclones.

In the first study of its kind so close to the equator, lead author James Bramante reconstructed 3,000 years of storm history on Jaluit Atoll in the southern Marshall Islands. This region is the birthplace of tropical cyclones in the western North Pacific — the world’s most active tropical cyclone zone. Using differences in sediment size as

Ancient storms could help predict future shifts in tropical cyclone hotspots

Nov. 16 (UPI) — To get a better sense of how climate change might alter the patterns of major ocean storms, shifting the parameters of tropical cyclone hotspots, scientists reconstructed 3,000-years of storm history in the Marshall Islands.

The analysis showed that during the Little Ice Age, storms more frequently struck Jaluit Atoll in the southern Marshall Islands.

The findings, published Monday in the journal Nature Geoscience, suggest differences in ocean warming strongly influence Pacific storm patterns.

By analyzing differences in sediment size, researchers were able to pinpoint the timing of extreme weather events. The data showed that prior to the Little Ice Age, storms hit Jaluit Atoll roughly once per century, but between 1350 and 1700 AD, the islands were struck by four cyclones per century — a significant increase.

By studying the affects of ancient climate change on storms patterns in the Northern Pacific, researchers were able to

Tropical Depression Eta to re-strengthen in Caribbean before entering Gulf; see forecast | Hurricane Center

Tropical Depression Eta is expected to move in to the Gulf of Mexico next week, but there are questions about its path after that, local forecasters say.

Eta made landfall in Central America as a Category 4 storm earlier this week before spinning back towards the Caribbean as it weakened. It is forecast to take a northwestern turn after it impacts Cuba.

“It is forecast to eventually get into the Gulf early next week, after that though there are a lot of questions,” local meteorologist Christopher Bannan wrote in a briefing.

Eta will regain tropical storm strength in the northwestern Caribbean Sea in the next day or two, forecasters say. It is currently located about 60 miles west of La Ceiba, Honduras. It has maximum sustained winds of 35 mph. It’s moving north-northwest at 8 mph.

“It’s time for people to put their eyes on Hurricane Eta because that hurricane

Tropical Storm Eta formed in the central Caribbean on Saturday, becoming the 28th named storm of the 2020 Atlantic hurricane season. This season has now tied the record for the most named storms in a season, previously set in 2005.

While the number of storms in 2005 was also 28, this is the first time the name Eta will ever be used. In 2005, there were only 27 named storms, with one unnamed subtropical storm being added to the tally in a post-season reanalysis by the National Hurricane Center.

2020 has been a remarkable hurricane season by many measures. This season also holds the record for the most tropical systems to make landfall in the U.S., with 11, and ties the record for most landfalling hurricanes at six.

Unfortunately, the overactive season shows no signs of stopping, at least through the middle of November, because the
