Tradeoffs between weaponry and fecundity in snapping shrimp queens vary with eusociality

Wed, 14 Mar 18 00:11:00 -0700

Amongst species of colonial snapping shrimp, the capacity for defense versus reproduction in queens varies with the level of cooperation, according to a study published March 14, 2018, in the open-access journal PLOS ONE by Sally Bornbusch from Duke University, USA, and colleagues.

Coral reef experiment shows: Acidification from carbon dioxide slows growth

Wed, 14 Mar 18 00:09:00 -0700

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated.

NASA finds strongest storms in newly formed Tropical Cyclone 13P

Mon, 12 Mar 18 00:07:40 -0700

Infrared satellite data showed Tropical Cyclone 13P quickly developed powerful storms with very cold cloud top temperatures. NASA's Aqua satellite analyzed the system in infrared light to determine where its strongest storms were located.

How the color-changing hogfish 'sees' with its skin

Mon, 12 Mar 18 00:10:10 -0700

The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes.

No fish story! Research finds marine reserves sustain broader fishing efforts

Tue, 06 Mar 18 00:16:10 -0800

In their examination of marine reserves, also known as marine protected areas or MPAs, around coral reefs in the Philippines, Robert Fidler and Ralph Turingan found evidence that MPAs helped to produce and maintain the more desirable, large-bodied and older fish within populations that have been fished by local fishermen for centuries.

Staying clean keeps seafish smart

Tue, 06 Mar 18 00:03:00 -0800

'Vet' service provided by smaller fish is key to keeping coral reefs healthy, a Canadian study finds.

A leopard may not change its spots but venomous creatures change their venom recipe often

Mon, 05 Mar 18 00:01:30 -0800

For a long time scientists believed that an animal's venom was consistent over time. However, through a close study of sea anemones, Dr. Yehu Moran of Hebrew University found that animals change their venom several times over the course of a lifetime, adapting the potency and makeup of their venom to suit changing predators and aquatic environments.

Playing both ends: Amphibian adapted to varied evolutionary pressures

Fri, 23 Feb 18 00:00:00 -0800

Caecilian, Siphonops annulatus, a limbless amphibian found throughout Brazil, has a concentration of enlarged mucous glands in its head region and a concentration of enlarged poison glands in its posterior region. These concentration appear to have evolved from different selective pressures: the ability to tunnel into the ground and to defend oneself from predators.

New mutant coral symbiont alga able to switch symbiosis off

Thu, 22 Feb 18 00:15:40 -0800

Researchers have identified the first spontaneous mutant coral symbiont alga to not maintain a symbiotic relationship with its host.

Coral reefs at risk of losing building material by end of century

Thu, 22 Feb 18 00:09:40 -0800

A new study suggests that by 2050, most coral reefs around the world are at risk of experiencing constant depletion of one of their building blocks - calcium carbonate sediments.

First evidence of surprising ocean warming around Galápagos corals

Wed, 21 Feb 18 00:02:00 -0800

A new analysis of the natural temperature archives stored in coral reefs shows the ocean around the Galápagos Islands has been warming since the 1970s. The finding surprised the research team, because the sparse instrumental records for sea surface temperature for that part of the eastern tropical Pacific Ocean did not show warming. Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific.

Sea urchins erode rock reefs, excavate pits for themselves

Wed, 21 Feb 18 00:06:30 -0800

Through their grazing activity, sea urchins excavate rock and form the pits they occupy. This activity may cause significant bioerosion of temperate reefs, according to a study published Feb. 21, 2018 in the open-access journal PLOS ONE by Michael Russell from Villanova University, US, and colleagues.

Study exposes misperception of poaching on the GBR and its remedy

Tue, 20 Feb 18 00:00:00 -0800

New research has revealed the tiny minority of fishers who poach on the Great Barrier Reef (GBR) think the illegal practice is justified, because they believe 'everyone else is doing it.'

First video of 'Dumbo' octopod hatchling shows that they look like mini-adults

Mon, 19 Feb 18 00:09:10 -0800

Researchers who've gotten the first look at a deep-sea 'dumbo' octopod hatchling report in Current Biology on Feb. 19 that the young octopods look and act much like adults from the moment they emerge from an egg capsule. Dumbo octopods are so named because their fins resemble Dumbo the elephant's ears.

Hurricanes Irma and Maria temporarily altered choruses of land and sea animals

Thu, 15 Feb 18 00:01:20 -0800

Audio recordings of Hurricanes Irma and Maria's passage over Puerto Rico document how the calls of coastal critters changed in response to the deadly storms. The hurricanes caused a major disruption in the acoustic activity of snapping shrimp, a reduction in insect and bird sounds, and potentially an intensification of fish choruses, according to new research presented at the Ocean Sciences Meeting Friday.

How the cuttlefish spikes out its skin: Neurological study reveals surprising control

Thu, 15 Feb 18 00:05:00 -0800

Wouldn't it be useful to suddenly erect 3-D spikes out of your skin, hold them for an hour, then even faster retract them and swim away? Octopus and cuttlefish can do this as a camouflage tactic. A new study clarifies the neural and muscular mechanisms that underlie this extraordinary defense tactic, conducted by scientists from the Marine Biological Laboratory (MBL), Woods Hole, and the University of Cambridge, UK, and published in iScience.

Snapping shrimp may act as 'dinner bell' for gray whales off Oregon coast

Tue, 13 Feb 18 00:02:50 -0800

Scientists have for the first time captured the sounds of snapping shrimp off the Oregon coast and think the loud crackling from the snapping of their claws may serve as a dinner bell for eastern Pacific gray whales, according to new research being presented at the Ocean Sciences Meeting here today.

Scientists pinpoint how ocean acidification weakens coral skeletons

Mon, 29 Jan 18 00:06:10 -0800

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

Billions of plastic items are sickening coral reefs

Thu, 25 Jan 18 00:13:00 -0800

A new study estimates that 11.1 billion plastic items are lodged along coral reefs across the Asia-Pacific, and that their presence increases the risk of coral disease from 4 to 89 percent, in some cases.

A 'marine motorhome for microbes': Oceanic plastic trash conveys disease to coral reefs

Thu, 25 Jan 18 00:12:20 -0800

For coral reefs, the threat of climate change and bleaching are bad enough. An international research group led by Cornell University has found that plastic trash -- ubiquitous throughout the world's oceans -- intensifies disease for coral, adding to reef peril, according to a new study in the journal Science.

Plastics linked to disease in coral

Thu, 25 Jan 18 00:12:00 -0800

How climate change weakens coral 'immune systems'

Mon, 22 Jan 18 00:15:20 -0800

Researchers at The Ohio State University and their colleagues have demonstrated how two separate effects of climate change combine to destabilize different populations of coral microbes -- that is, unbalance the natural coral 'microbiome.'

Kicking an old can of worms -- the origin of the head in annelids

Mon, 22 Jan 18 00:05:10 -0800

Researchers at the Royal Ontario Museum and the University of Toronto have described an exceptionally well-preserved new fossil species of bristle worm called Kootenayscolex barbarensis. Discovered from the 508-million-year-old Marble Canyon fossil site in the Burgess Shale in Kootenay National Park, the new species helps rewrite our understanding of the origin of the head in annelids, a highly diverse group of animals which includes today's leeches and earthworms.

Recent advances in understanding coral resilience are essential to safeguard coral reefs

Thu, 18 Jan 18 00:04:50 -0800

The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.

Aid for oceans and fisheries in developing world drops by 30 percent

Wed, 17 Jan 18 00:06:50 -0800

Thu, 11 Jan 18 00:02:10 -0800

Scientists have used a new research approach to show that warming temperatures are turning one of the world's largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes.

Study finds source of toxic green algal blooms and the results stink

Tue, 09 Jan 18 00:13:50 -0800

Florida's St. Lucie Estuary received national attention in 2016 as toxic green algal blooms wreaked havoc on this vital ecosystem. A new study contradicts the widespread misconception that periodic discharges from Lake Okeechobee were responsible. Water samples gathered and tested in the year-long study provide multiple lines of evidence that human wastewater nitrogen from septic systems was a major contributor to the high nitrogen concentrations in the estuary and downstream coastal reefs.

Trawl of Red Sea surface waters finds little plastic

Mon, 08 Jan 18 00:03:30 -0800

The Red Sea has relatively low amounts of floating plastic debris in its surface waters due to fewer sources or faster removal.

Three new species of zoantharians described from coral reefs across the Indo-Pacific

Thu, 04 Jan 18 00:14:10 -0800

Three new species of zoantharians -- relatives of the better-known hard corals and sea anemones - were discovered by researchers based in southern Japan. One of them, Antipathozoanthus remengesaui, was named after the current president of Palau, Tommy Remengesau, in honour of his and the nation's support to the authors and marine conservation as a whole. The species, which can be found widely across the Indo-Pacific, are described in a study published in the open-access journal ZooKeys.

The window for saving the world's coral reefs is rapidly closing

Thu, 04 Jan 18 00:05:10 -0800

For the first time, an international team of researchers has measured the escalating rate of coral bleaching at locations throughout the tropics over the past four decades. The study documents a dramatic shortening of the gap between pairs of bleaching events, threatening the future existence of these iconic ecosystems and the livelihoods of many millions of people.

The ocean is losing its breath -- here's the global scope

Thu, 04 Jan 18 00:05:00 -0800

In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than tenfold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms.

Frequency of coral bleaching has increased nearly fivefold since the 1980s

Thu, 04 Jan 18 00:04:20 -0800

Globally, the frequency of severe coral bleaching events has increased nearly fivefold in the past four decades, from once every 25 to 30 years in the early 1980s to once every 5.9 years in 2016, a new study reports.

The ocean is losing its breath. Here's the global scope

Thu, 04 Jan 18 00:15:00 -0800

In the past 50 years, the amount of water in the open ocean with zero oxygen has risen more than fourfold. In coastal water bodies, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms. To halt the decline, the world needs to rein in both climate change and nutrient pollution, an international team of scientists asserted in a new paper published Jan. 4 in Science.

Sowing corals: A new approach paves the way for large-scale coral reef restoration

Wed, 03 Jan 18 00:14:00 -0800

Scientists pioneer in developing a novel approach to simply sow coral recruits onto degraded reefs like farmers scatter seedlings on a field. With this innovation, formerly costly and time-consuming handling can be minimized, and may allow for effective large-scale reef restoration. The study led by SECORE International was recently published in Scientific Reports.

The Caribbean is stressed out

Thu, 28 Dec 17 00:00:00 -0800

Forty percent of the world's 2.5 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coasts from the Caribbean Coastal Marine Productivity Program (CARICOMP).

Conserving coral communities

Wed, 27 Dec 17 00:09:30 -0800

For years, people have sought to stop the loss of coral reefs by transplanting corals grown in underwater 'nurseries' to damaged reefs, but little work had been done to evaluate how effective such efforts were. A new Harvard study, however, suggests those projects have a positive impact on local fish populations, both in the short term and over time.

Tiny polyps save corals from predators and disease

Fri, 22 Dec 17 00:14:50 -0800

Corals may have unexpected allies in improving their health and resilience.

New species of marine spider emerges at low tide to remind scientists of Bob Marley

Fri, 22 Dec 17 00:16:00 -0800

It was 02:00h on 11 January 2009 when the sea along the coastline of Australia's 'Sunshine State' of Queensland receded to such an extent that it exposed a population of water-adapted spiders. The observant researchers, who would later describe this population as a species new to science, were quick to associate their emergence with Bob Marley's song 'High Tide or Low Tide'. Their study is published in the open access journal Evolutionary Systematics.
