Does species richness ensure #resilience? Karatayev et al. show that it does not: Alternative consumer- or resource-dominated states can arise in #foodWebs with low trait #diversity or high functional redundancy. Thus diversity only limits the #feedbacks that can produce #alternativeStableStates.

No hay nada como leerse constantemente la bibliografía para ver cómo los investigadores están cada día más preocupados por la posibilidad real de un colapso ecológico y social.

Por ej. Peter Stott de Met Office "estamos siendo testigos de un cambio climático a un ritmo aterrador"[...] “Me hace sentir triste y ansioso”

A nice review on the drivers shaping the huge #Eurasian #forest-steppe by Erdos et al., emphasizing #Alternative #Biome States & #feedbacks (https://doi.org/10.1016/j.tplants.2019.11.003, https://doi.org/10.1016/j.tree.2022.03.008)

How come I haven't seen it before?

"Over the past 20 years, wetland methane emissions have risen by 1.2-1.4m tonnes per year. This is faster than the average projection under the most pessimistic emission scenario (RCP8.5), which shows growth of 0.9m tonnes of methane per year.

The paper “adds further weight to conclusions made in many other recent studies that #methane emissions associated with #wetlands are rising fast in response to positive #climate #Feedbacks "

The latest episode of #RadioEcoshock reviews Hansen's new paper currently under review. I already realized this, how they've under-called the impacts and #feedbacks And I already over my initial shock. The #IPCC is low-balling their projections. #climateaction - #globalwarming #Arctic #survival #scientists #disaster https://www.ecoshock.org/2023/01/hansen-a-world-10-degrees-c-hotter.html

Proponents of capitalism and economic libertarianism are constantly demagoguing that world conditions are "better than ever."

Every year this gets more false. Particularly because fossil fueled climate change is wiping out prior gains.

Growth in renewable energy has reduced the increase in temperature in the past 5 years. But we're still far off track from meeting #climate goals. Runaway climate #feedbacks are still a looming threat.

#Capitalism is the disease, and can never be the cure.

You can see how the #landscape modelled the fire, and how the fire modelled the landscape .. #feedbacks are the rule (https://www.sciencedirect.com/science/article/abs/pii/S0169534722000611)

#Feedbacks as an unifying concept in #ecology & #evolution: Linking #niche construction (population scale), alternative #biome states (community scale) & #Gaia (global scale) to understand the #resilience of our #biosphere

I found some time to refine my #fediversemap : new instances about 4500 now and more info if ever they serve to choose an instance. I let you test it. #feedbacks welcomed

A I forgot the best you can now use it to send your address by adding ?instance=yourinstance at the end of the url a small button allows you to retrieve the url in your clipboard. Ex:

J'ai trouvé un peu de temps pour peaufiner ma #fediversemap nouvelles instances environ 4500 maintenant et plus d'infos si jamais elles sert a choisir une instance. Je vous laisse tester. #feedbacks welcomed

A j'oubliais le meilleur vous pouvez maintenant vous en servir pour envoyer votre adresse en rajoutant ?instance=votreinstance à la fin de l'url un petit bouton vous permet de récupérer l'url dans votre presse papier. Ex:

Time for an #introduction #neuhier #newhere:

I am a #marine #biogeochemist, working with the #ocean #circulation model #FESOM and the ocean #biogeochemistry #model #REcoM.

I am interested in the #cycling of #carbon and #nutrients, and how the ocean carbon #uptake and #ecosystems (well, #plankton) change in a #highCO2 and #warming #world.

I lead the @helmholtz Young Investigator Group #MarESys Marine Carbon and Ecosystem #Feedbacks in the #Earth System.

I hope these were enough #hashtags
