Lichens indicate airquality and climateconditions. I found the #species below in #Jungfernheide #forest #Berlin. While #Parmelia #sulcata requires light, but is flexible, #Hypotrachyna #afrorevoluta needs warm, nitrogen-poor #environments and clean air. The latter is rareer in #Germany, but spreading eastward based on #globalwarming. D. Masson (2004) found it on #treetrunks and #branches.

Lichen Hypotrachyna afrorevoluta on a branch nearby lake Flughafenseen in forest Jungfernheide Berlin. The species prefers warmth, clean air and some slight acidity. It is sometimes named as putative sister species of the morphologically rather similar Hypotrachyna revoluta. They differ by their thallus surface texture (rough in H. afrorevoluta) and the thallus lobe endings lesser bulged downward in H. revoluta and stronger bulged downward in H. afrorevoluta. Soridia are more granular in the latter, its rhizinia are black and stiff and not brown, slim and wavy. H. afrorevoluta was described from specimens in Africa, since the ends of 1990s the species was also discovered in Europe, formerly mistaken with H. revoluta. It is seemingly in debate, whether it is really the same species as in tropical Eastern Africa (Kenya). © Stefan F. Wirth, Berlin, March 202

#Freshwater #lakes,like #Flughafensee #Berlin, play a complex #role in #globalwarming. Their #sediments are important #carbonsinks. However, they also release #CO2/#methane through microorganism activities. Furthermore, #lakeswarmup faster than surrounding air. L. Huang et al.(2024) address this and predict #shifts in #aquaticspecies #distributions and rearrangements of #freshwaterhabitats.

Wirth Freshwater lakes interact with global warming in a complex and sometimes contradictory way, binding CO2 in their sediments but also releasing CO2 and methane through decomposition processes. They also warm up faster than their surroundings. On the other hand, the ecological conditions of the surrounding area are important for how "climate-friendly" a lake is. Berlin's Flughafensee (Airport Lake) lies in the middle of a forest (Jungfernheide Forest) and is partially protected by fences as a bird sanctuary. Therefore, an almost untouched shoreline vegetation thrives there, including marshy areas and reedbeds.

How moss could help roads cope with heavy rain and reduce air pollution


Already some countries are experimenting with using #moss in built-up areas to absorb air #pollution. As countries search for #nature-based solutions to #climate and #environmental challenges, #roadside moss is starting to attract attention. So could mossy motorway banks work?

Moss could offer environmental benefits over grass, from trapping air pollution to slowing #rainwater runoff during heavy storms.

How moss could help roads cope with heavy rain and reduce air pollution

Moss can absorb pollution caused by traffic and grow in thin soil.

The AI boom has plunged a small Pennsylvania town into chaos.

Data centers will swallow 14 percent of Archbald, evict a trailer park, and border many residential properties. Who's to blame is a matter of fierce debate. #ClimateChange #ClimateCrisis #GlobalWarming

You haven’t noticed that the days are getting ever so slightly longer, but a new study shows that they are — and it points to climate change. @euronews explains what’s happening and why it can be a problem:

‘Unprecedented in the past 3.6 million years’: How human-made climate change is making days longer

Human activity is responsible for slowing Earth’s spin and making days longer, according to a new study.
