I've made a collection of eco-evo journals on BlueSky so that other scientists/ecologists/conservationists can easily find and access them:

Which ones am I missing? Please let me know if I've overlooked a journal! 🌍🧪💚 #AcademicSky

When the water gets warmer, life gets out of balance. Researchers at the #UDE have published #ThermoFresh, the world's largest freely accessible data collection on the heat tolerance of freshwater species.

Er komt weer een extreemrechtse demo aan - en we veranderen 'm in een sponsorloop voor het goede doel!

Sponsor nu een demonstrant via www.degoedezaak.org/sponsor-een-... en zaai hoop in plaats van haat💪💚

My quoted tweet below was mocking RFK Jr. because he should know better as head of HHS and someone who claims to 'follow the science.' But also - I think this is a common misconception so I'm going to address it earnestly.

Why do we conduct research, if not to 'make proof?'

I, a scientist, definitely do studies to make proof.

Ongeveer 11.000 statushouders krijgen jaarlijks voorrang op een huurwoning en ongeveer 100.000 tot 200.000 expats krijgen voorrang op een huurwoning dankzij de expatregeling, die het leven in de grote steden volstrekt onbetaalbaar heeft gemaakt, maar daar hoor je onze Volendamse nepregent niet over.

Hey, folks, please check out the new Drawdown Explorer.

It’s the world’s leading resource for science-backed climate solutions. And now it provides the most up-to-date, localized, actionable intelligence to help scale these solutions out in the world.

Sorry, jag borde ha skrivit "input" eller "thoughts about" eller ngt liknande! Tack för förtydligandet :)

Thanks!

To be clear: These are threshold values that already have been accepted in the permit for this land reclamation project.

I still think the threshold values, content and possible maximum amounts of pollutants that could end up in the water, are interesting aspects to talk about.

Lista över gränsvärden (mg/kg TS) för tillåtna föroreningshalter i massor som ska användas för att fylla ut en grund havsmiljö.

Någon ekotoxikolog/kunnig som vill kommentera gränsvärden?

Kontext: 3 000 000 m3 ska dumpas. Massor dumpas först direkt i, därefter i vatten med kontakt med, havsområdet.

Er gaan dus weer miljarden subsidies naar de allergrootste vervuiler van Nederland, al vele jaren in handen van een industriële miljardairsfamilie uit Azië.

Het blijft bijzonder hoe die zgn. stikstofcrisis steeds de kleine ondernemer raakt - de aannemer, de boer, etc. - maar nooit het grootbedrijf.

The Swedish UPPSALA DECLARATION now has 2,557 signatories. The EUROPEAN DECLARATION is catching up with 2,458 from EU/EEA/UK/CH. All signatories refuse to collaborate with Israeli institutions complicit in illegal occupation, apartheid, genocide, and other violations of international law.

ALERTA!

De regering heeft zonder veel bombarie een internetconsultatie ingediend om de tijd dat je hier moet wonen om Nederlander te worden gigantisch op te rekken.

Strax innan toppmötet COP30 visar det lilla landet Surinam hur man går före och visar vägen genom att skydda 90 procent av sin skog. Kan det inspirera andra länder? Kanske Sverige där mindre än 6 procent av den produktiva skogsmarken har ett formellt skydd?

Surinam ska skydda 90 procent av sin skog
Surinams nya president har gjort en rivstart för att bevara landets natur och det motiveras även av ekonomiska skäl.

"it took about 65 years to exceed the 0.5-degree limit, just 28 years to reach the 1.0-degree limit, and it will be about 17 years if we exceed the 1.5-degree limit on a moving average in 2025 or 2026. This means that the period for each jump of 0.5 degrees is getting shorter and shorter."

There is so much in the news cycle these days that the complete dismantling of the Forest Service -- so *our* forests can be auctioned off to Big TImber -- is unfortunately getting little air play. But if this happens, US landscapes may be almost unrecognizable in a decade, and never coming back. 🌍

Using an emergency declaration, Trump’s timber production executive order would ease environmental protections so as to greatly expand logging in the national forests.

A report from our friends at @highcountrynews.org:
The dismantling of the US Forest Service is imminent
The public has less than a week remaining to comment on the administration's plans.

So, it seems the arguments for scientists flying around the world

to have meetings about environmental degradation & biodiversity loss

are that: it’s nice to meet people in person & it’s hard to coordinate around different time zones

Los van de inhoud van dat proefschrift zelf: mensen kunnen toch ook na hun verdediging besluiten om onzin te gaan verkopen? Kijk ook naar Plasterk bijv.
