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.

"Such “laws” thus are really rules of thumb, statistical regularities that admit many exceptions and variations. Why do such regularities exist at all? Do they represent something unique to the number of species on islands? Or are they the natural consequences of a set of local rules of interaction that are common to a whole class of #ComplexAdaptiveSystems [...]?" [1]

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.

"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

Challenging threshold-based attempt to translate the complexity (so many unknowns, #TippingPoints, nonlinear #feedbacks, #PrecautionaryPrinciple ) and to break through minds who might seem to be reeling in a daze with the actual magnitude of the #ClimateCrisis, and the urgency to act.

#EvolutionaryEcology

One of my main blocks of creativity right now is how to make it comfortable to check every column on #mastodon, without the sense of "visual pollution".

I'm open for any #feedbacks and recommendations to take as an inspiration.

"Global #warming in the pipeline is greater than prior estimates.
Eventual #GlobalWarming due to today's #GHG forcing alone -- after slow #feedbacks operate -- is about 10°C.
Human-made #aerosols are a major #climate forcing, mainly via their effect on #clouds."

"Researchers can no longer afford to track global #transformations of the Earth system in disciplinary silos. Instead, #ecologists and #climate #scientists need to establish a joint agenda, so that humanity is properly forewarned: of the risks of removing #biodiversity buffers against #ClimateExtremes, and of the risk of thereby amplifying these extremes."

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:

To the artist community I have a question, is it wrong to ask for feedback or tips after posting your work?

I've been don't this for 3 years, but even though I know I have improved , I still feel stuck or I fell like I haven't made much progress, I constantly made that question many times but sadly because of my low audience I never get an answer, I even keep asking myself if I'm doing something wrong.

Hi everyone. New server. I'm Ben Sanderson - #climate scientist at #CICERO in Oslo, previously at #NCAR Some hashtags:

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 🙃 🤓
