CO2 Benefits the “Rats and Cockroaches” of Marine World – Scientific American

CO2 Benefits the “Rats and Cockroaches” of Marine World

Ocean acidification may be driving a cascade of changes that drains marine biodiversity

By Adam Aton, ClimateWire on July 7, 2017

Beneath the waves, swelling levels of carbon dioxide could be boosting some species to ecological dominance while dooming others.
A study published yesterday in Current Biology suggests ocean acidification is driving a cascading set of behavioral and environmental changes that drains oceans’ biodiversity. Niche species and intermediate predators suffer at the expense of a handful of aggressive species.

Sea-level rise and coral bleaching often dominate discussions about how climate change affects the ocean, but a host of more subtle—and harder to research—trends also play a role in reshaping the world’s marine ecosystems. Among the most pressing questions is how fish react to rising levels of CO2, said Tom Bigford, policy director at the American Fisheries Society.

“The hurdles for behavioral changes are far lower than the hurdles for life and death,” said Bigford, who worked with fish habitats at NOAA for more than three decades.

Now, for the first time, researchers from the University of Adelaide in South Australia have cataloged the changing ways marine species interact with each other.

For three years, they observed marine environments near undersea volcanic vents where CO2 levels are high—providing a window into the future acidity of ocean water—along with adjacent areas of normal acidity. They also conducted behavioral experiments on fish from the different zones to test their responses to food and habitat competition.

Receding kelp means less habitat for intermediate predators, with about half as many near the volcanic vents.

But the acidified conditions proved to be a boon to what the researchers called “the marine equivalent to rats and cockroaches”—small fish with low commercial or culinary value.

Snails and small crustaceans can flourish in high-CO2 conditions, providing plenty of prey for those small fish. And their high risk-taking behavior and competitive strength, coupled with the collapse of predator populations, allowed them to more than double their population.

In water with higher CO2, the dominant species were willing to adapt to riskier habitats, preferring bare surfaces instead of turf while subordinate species were nearby.

Mimicked predator attacks also showed the dominant species adopted riskier behavior in higher-acidity water, fleeing shorter distances than the fish in water with normal acidity. Subordinate species showed no change.

Rare and specialist species are the most vulnerable to climate change, even though they “contribute disproportionately to [ecosystems’] functional diversity,” the researchers wrote.

To counter that diversity loss, the researchers suggested stronger fishing protections for predators.

Aromatherapy Oils for Summer

GrannyMoon's Morning Feast

Dinners at dusk, afternoon barbecues, and sleeping under the stars happen to be as inviting to bugs and mosquitoes as they are to vacationers. Fear not: There are lots of oils that will keep you bite-free—and plenty that will prevent you from smelling like an exterminator.

My power players for summer are ones that are very accessible to find and use, and they’re a great fragrance fix if you fancy something light. There’s spearmint for keeping cool and fresh, which is not as much as a potential skin irritant as peppermint, plus it’s a great antibacterial oil while being very energizing when you are feeling sluggish from the humidity. For a great pick-me-up and refresh, look no further than the citrus family. I’m all about sweet orange and red and yellow mandarin. Why? They’re the safest to use with sensitive skin when…

Sixth mass extinction

Many scientists say it’s abundantly clear that Earth is entering its sixth mass-extinction event, meaning three-quarters of all species could disappear in the coming centuries.

But that’s not even the full picture of the “biological annihilation” people are inflicting on the natural world, according to a study published Monday in the Proceedings of the National Academy of Sciences. Gerardo Ceballos, an ecology professor at the Universidad Nacional Autónoma de México, and his co-authors, including well-known Stanford University biologist Paul Ehrlich, cite striking new evidence that populations of species we thought were common are suffering in unseen ways.

Their key findings: Nearly one-third of the 27,600 land-based mammal, bird, amphibian and reptile species studied are shrinking in terms of their numbers and territorial range. The researchers called that an “extremely high degree of population decay.”

The scientists also looked at a well-studied group of 177 mammal species and…

Serbia: Help Rescued Pozega Dogs Get Well After Their Hellhole Suffering.

Serbian Animals Voice (SAV)

https://www.facebook.com/PozegaDogsAdoptionPage/

LOZNICA RESCUES NEED HELP WITH THEIR VACCINATION’S, SPAYING’S AND NEUTERING’S:  LET’S DO THIS RIGHT FOR THESE DOGS!

After those celebrating moments when we had your breathtaking support and we were fighting together to save as many lives as possible, came the time when isolation period was over and the need for vaccinations, testings, spaying’s and neutering’s has started.

All 49 last saved  dogs plus almost 90 previously rescued are now ready for their first vaccination against infectious diseases and each every one of them needs 4D testings, ultra sounds, neutering’s and spaying’s.

WE ARE IN THE MIDDLE OF SPAYING’S AND NEUTERING’S, BUT WE WERE FORCED TO STOP AS ALL FUNDS ARE AT THE ROCK BOTTOM, CONSUMED BY THE COSTS OF THE RESCUE AND IMMEDIATE AFTERCARE AT THE VETS.

Many of the dogs who were already brutally butchered with primitive surgery in the kill shelter, need their neuter and spaying redone properly. On the…

South Africa’s Claimed ‘Need’ for Wildlife Utilisation

So, let’s take a quick look at some of the recent Republic of South Africa’s, Department: Environmental Affairs (DEA) ‘thinking.’

African Lion

IWB Letter to the South African High Commissioner, London, 11 July 2017

In the DEA’s 28 June 2017 media statement – “Lion export quota for 2017 communicated to the CITES Secretariat in line with CITES requirements” the DEA referenced a 2015 study by TRAFFIC:

A 2015 study commissioned by TRAFFIC raised concerns around the shift in lion and tiger bone trade; namely that when the trade in tiger bone was banned; the trade shifted and bones were sourced from South Africa, available as a by-product of the hunting of captive bred lions.”

South Africa reiterates its concern that if the trade in bones originating from captive bred lion is prohibited, lion bones may be…

Vegan Black Cherry Ice Cream

Feed Your Beauty

Vegan Black Cherry Ice Cream

Yesterday was my dad’s birthday, and this year I thought it’d be fun to re-create one of his favorite ice cream flavors. Growing up, I used to love visiting the near-by ice cream stand, or whippy dip as it we called it. Like most establishments of its kind, it was only open from late spring until Labor Day, so you had a limited time to enjoy all those swirly soft serve and hand-dipped cones. Whenever I’d go with my parents, my mom would usually choose something involving chocolate, while my dad would almost always choose black cherry ice cream. I’d often pick something neon colored or outrageously flavored or doused in rainbow sprinkles, and while it would always seem like a good idea at the time, I’d ineviteably ask my dad if I could try some of his cherry ice cream. It was a classic.

Serbia: Azea Has A Cancer, But Needs Funds To Sort It – Please Help – See Below.

Serbian Animals Voice (SAV)

PLEASE read the story about Azra, so heartbreaking.  Azra doesn’t deserve this, so PLEASE anyone who might help her to continue the therapy, do it!

We have to win this battle together!

SHARE EVERYONE PLEASE!

The Story

This is Azra, the beautiful girl whose ‘owner’ obviously does not care too much about her because he allowed her to come to this situation, and the situation is following: the carcinoma of the vagina whose type we still do not know because it requires a departure to vet clinic in Belgrade, after the suggestions of the veterinarians in Bor where Azra lives, and the pathohistology has to be done.

What the veterinarian suggests is a quality surgery of an experienced surgeon, which again requires a visit to Belgrade, and for which there is no money.

Jovan Joja Cvetkovic took over the dog as soon as he found out about her, since ‘the…
