Si je vous montre cette photo, vous n'allez pas nécessairement pas sauter au plafond. Je vais donc vous raconter pourquoi elle est exceptionnelle ! #Thread #Science #Mediterranean #fish #ecologie #biodiversity #environnement #Underwater #photography #photo #OLYMPUS Image
Ceci est un Cline argenté, pris en photo le 7 novembre dernier. Un poisson de fonds rocheux que l'on estime très commun dans les zones battues, proches de la surface. Il se nourrit d'invertébrés trouvés sur les algues. Il dépasse rarement le premier mètre de profondeur. Image
On le reconnait à sa large échancrure au début de sa nageoire dorsale unique, ses marbrures mimétiques, et ses nageoires pelviennes (sous le ventre) réduites à deux rayons, un long et un court. Image

C'est l'Automne, saison des Marbrés !
En effet, on peut observer actuellement des jeunes marbrés sur nos côtes, au niveau des zones de sables quasi exclusivement. Image
Ce poisson, Lithognathus mormyrus, mesure jusqu'à 55cm, possède un dos zébré caractéristique avec un profil rectiligne. C'est une espèce qui cherche ses proies, des invertébrés, dans le sable et le sédiment. Image
Ses solides molaires sont capables de broyer de petits oursins et des crustacés. A noter qu'il est protandre, c'est-à-dire qu'il est mâle vers 2 ans puis femelle entre 4 et 7 ans. La capture de tout individu de moins de 20 cm est interdite quelle que soit la technique utilisée. Image

🚨Paper Alert🚨

Marine protected areas #MPAs are increasingly promoted as #ocean-based #solution to #ClimateChange, but their contribution to climate change #adaptation and #mitigation remains contentious. Our meta-analysis of 22,403 papers brings clarity. Link below.

🧵(1/17)
🙈Spoiler alert🙉

#FullyProtected #MPAs can can significantly enhance:

©️ carbon sequestration
🌊 coastal protection
🐟 biodiversity
🐡 reproductive capacity of marine organisms
🎣 fishers’ catch
💰 fishers’ income

🧵(2/17)
We identified the potential “climate pathways” through which #MPAs could contribute to #ClimateChange #mitigation and #adaptation. First along mitigation and adaptation dimensions, and then distinguishing among #ecological and #social dimensions of adaptation.

This week, people have been discussing if eating #oysters conflicts with following a plant-based diet.

Today, we’re taking a look at the definition of sentience and #veganism—and at animal species that have been proven to be more sentient than humans used to think. 👇1/14 Image
Although there is legal and scientific disagreement about #sentience, there are some standards that are broadly accepted.

According to @SentienceInst, sentience is simply the ability to have positive and negative experiences, including pain. 2/14
sentientmedia.org/sentient-being/
The concept of animal #sentience is important for ethical reasons.

If #animals are sentient beings capable of feeling pain, most humans would agree that it is morally wrong to cause unnecessary pain or suffering to them. 3/14

"Animal-source foods are believed to contain the #meatfactor, a substance enhancing the absorption of micronutrients from plant-based foods"

academic.oup.com/advances/advan…
"it has been suggested that peptides, phospholipids &
mucopolysaccharides released during digestion of muscle tissue contribute in facilitating #iron uptake by mediating the formation of readily absorbable ferric oxohydrate nanoparticles"
But: "the enhancement in nonheme iron absorption is not at all influenced by the presence of heme in the muscle tissue [..] heme-free beef and heme-free chicken protein maintained the enhancing effect on nonheme iron absorption"

Fascinating world of ancient #glass: A #Roman glass bottle in the shape of a #fish.
Only a small number of mould blown fish-shaped bottle such as this one are known, they were produced in a workshop in the eastern Mediterranean, probably in Syria. We don't know what...1/3
....these bottles were used for, perhaps the shape relates to the content (garum/fish sauce).

Found in a burial in the necropolis of Zadar-Relja, dating 1st/2nd c. AD. 2/2

June 8 marks #WorldOceanDay.

We honor this day by highlighting the need to protect marine life from human #fishing activities—a step that has the potential to both tackle biodiversity loss and the ongoing climate crisis. @WorldOceansDay👇 1/10
Ocean ecosystems are vital since oceans:

🗺️ make up 70% of Earth’s surface
🫁 produce 80% of the oxygen we breathe
🐠 house 80% of all life on Earth

At the same time:
🎣98.5% of the #ocean is open to fishing fleets

Thread on #Magnesium and why it is fundamental for our #health. #micronutrients
..many people debate the various ratios of #macronutrients like #protein, #fat, and #carbohydrates in their diet to find their optimal health. Which is great as we are #bioindividuals but most miss out on #micronutrients like #vitamins and #minerals.
The way our bodies are able to use the #macronutrients is fully dependent on how our #enzymatic pathways are influenced by various #micronutrients. One of the most important amongst is #magnesium.

Did you know that this week marks #EndangeredSpeciesDay and #BiodiversityDay?

We honor these days by highlighting the need to change our eating habits and fashion choices to protect animals from going extinct.👇1/10
Animals play a crucial role in maintaining a healthy #environment. For example:

- beaver dams prevent fires
- squirrels help trees take root
- #fish feces can lock carbon away for 600 years
- elephants create water sources for other species

At Sentient Media, we report on an industry that touches all our lives yet operates in secrecy: factory farming.

On #WorldPressFreedomDay, we call on governments to lift #AgGag laws and share 13 findings we could only report thanks to the help of undercover investigators.👇1/17 Image
“Ag-gag” laws punish whistleblowers and investigators for recording footage inside #FactoryFarms.

In 2021, @ALDF released a film on how #AgGag laws conflict with the First Amendment while concealing pollution, food safety threats, and animal cruelty. 2/17

Current research on microplastics is the stuff of nightmares-

They’re dangerous, they’re spread through our food, they're in the air... they’re everywhere

Thread 1/x
#health #ClimateCrisis #PlasticPollution #food
Much of the research is trapped behind paywalls, and only reported on in a limited, fragmented pattern

-like so much else when large corporations cause environmental damage and impose widespread health impacts on the public

2/x
#health #ClimateCrisis #PlasticPollution #food
The growing risks of microplastics are a direct function of an ongoing push by the same sociopathic corporations that are driving the climate crisis

What's happening?

@savethesevern involves Wales’ #GeigerBay coalition and groups from south west England.

We’re trying to halt the dumping of sediment from the construction of the @hinkleypointc in the Marine Protected Area near Portishead, #Bristol

🧵⅕
We urge the Marine Management Organisation to revoke the license granted earlier this year to @edfenergy to dump the waste.

We believe it puts @The_MMO in breach of its international obligations to protect the Severn Estuary’s marine environment.

🧵 ⅖
We also demand that the UK’s Secretary of State for Environment, Food and Rural Affairs, George Eustice, acknowledges the ban on dumping that causes harm in the Marine Protected Area, and instructs @the_MMO appropriately.

In general, humans work hard to nurture religion, economic progress, sense satisfaction, and spiritual knowledge, with the goal of extending their lives, gaining reputation, and enjoying material riches.

1. Both predators and prey animals use camouflage to their advantage.

Prey animals blend in with the background, so hungry predators pass right by them.

🧵 Start of a thread with some amazing videos on #Camouflage.

I like this one. 🙂

2. But predators use camouflage too.

The striated frogfish (Antennarius striatus) walks the seafloor right up to its unsuspecting prey.

It has a prognathous mouth that launches an attack on prey in as fast as 6 milliseconds.

Economic Agility in the Face of COVID19 and the Soul of the Ugandan Economy: A Personal Reflection

So, the "COVID Fish" is ready for harvest. A few months ago, I shared a brief story on how the race for economic survival had forced me to venture into #fish farming. A thread...
When #COVID19 erupted, I initially thought that it would be a passing wave. In March 2020, I travelled to Germany in spite of the unfolding global public health risk. I was only lucky that Uganda went into full lockdown just 2 days after I had returned.
As per the Ministry of Health's guidelines, I self-isolated for 2 weeks since Germany was a high-risk country. I also invited the medics to test me and I tested negative. However, the worst was yet to come. These were the longest 2 weeks of my life and a full lockdown was imposed

Today, on #TheMisplacedMenagerie -

We report the exotic (for #India) apple #snail, #Pomacea diffusa, also known as the spike topped apple snail, from the #Mumbai region, as part of our ongoing studies on #urbanwildlife, and the #ecology of introduced species, in #India, Mumbai.
The study was officially published in the 'ELA Journal of Forestry and Wildlife' - a peer reviewed #science journal, which is also the official journal of the #Maharashtra State #Forest Department.

Link to paper: researchgate.net/publication/35…

Spiked Topped Apple Snails in #Mumbai (and other parts of #India) are the direct result of the #aquarium trade - either as accidental, or deliberate releases from home aquaria.

In the #LongFoodMovement report, we're reminded that the world’s 30 million artisanal #fishers and workers provide nearly half of the #fish we eat (@IPBES, 2019).

But with #climatechange & island/ocean grabbing, small-scale fishers & their communities are in peril.

🧵Thread 👇🏾
Island/#ocean grabbing is likely to intensify as countries seek to solidify their influence, their #food supply chains, & their global sourcing and distribution networks. For example, in the #RedSea region, conflicts over fish & other marine resources threaten rich #biodiversity.
Meanwhile, in the South China Sea, said to
have some of the highest marine #biodiversity on earth, #China has been building airstrips, ports & other facilities on disputed islands & reefs, w/ the apparent aim of establishing military bases (cf. Ives,
2016).
