Kann mir hier jemand einen Tip geben, wie / wo ich die Art dieser kleinen sicher bestimmen (lassen) kann? Ich dachte ja zuerst an Tiegerschnegel, die durchgehenden, klar abgegrenzten Streifen lassen mich da aber inzwischen dran zweifeln. Ich habe sie in einem Pflanzkübel „importiert“ & bin mir jetzt unsicher, ob ich sie in meinem Garten willkommen heißen soll (mehr Diversität & Konkurrenz) oder mir damit eine Plage einhandle… Momentan sind sie noch in Quarantäne. #molluscs #Schnegel #Schnecken

#AtlantaInclinata #Atlantidae #Gastropods #Molluscs #MolluscMonday finally I ended with this stage on my thesis, identifying all this snails on my samples were too difficult because I’ve never been in this kind of job before in taxonomy, but thanks to Maria Moreno-Alcántara I was able to do it because of her MSc thesis material

In her #JEB100 ECR Spotlight, ecologist Nicole Martin discusses how welks cope well with extreme temperature after experiencing a blast of warmth with increased water acidity and why Tomanek & Somero's 1999 JEB paper (https://bit.ly/3Cmu2Xm) is one of her favourites

Ah, and because this is also possibly relevant to #InverteFest, c&p of a toot f mine from a few days ago:

I am becoming a bit frustrated with the lack of resources about drawing animals _other than_ mammals or birds. Can anyone here recommend anything that goes further than just the normal Dynamic Sketching classes? Books, websites, videos, anything?

I mean cats are cool and all but so are #insects, #arachnids & #molluscs, know what I mean?

boosts welcome!

The water snails like to bask in the sun while they eat. They are clearly dragging pond weed onto the cork mat somehow, though I haven't seen them do it.

Ancient #Maya masons had a smart way to make #plaster stronger

Up close, the Mayas' timeless recipe from #Copán looks similar to mother-of-pearl.

By Rahul Rao, Apr 19, 2023

[Recent discoveries] "seemed to confirm past archaeological and written records suggesting that ancient Maya masons mixed plant matter into their plaster. The other standard ingredients (lime and water) wouldn’t account for complex carbon chains.

"To follow this lead, the authors decided to make the historic plaster themselves. They consulted living #masons and Maya descendants near #Copán. The locals referred them to the #chukum and #jiote #trees that grow in the surrounding #forests—specifically, the sap that came from the trees’ bark.

"The authors tested the sap’s reaction when mixed into the plaster. Not only did it toughen the material, it also made the plaster insoluble in water, which partly explains how Copán survived the local climate so well.

"The microscopic structure of the plant-enhanced plaster is similar to nacre or mother-of-pearl: the iridescent substance that some molluscs create to coat their shells. We don’t fully understand how #molluscs make nacre, but we know that it consists of crystal plates sandwiching elastic proteins. The combination toughens the sea creatures’ exteriors and reinforces them against weathering from waves.

"A close study of the ancient plaster samples and the modern analog revealed that they also had layers of rocky calcite plates and organic sappy material, giving the materials the same kind of resilience as nacre. 'They were able to reproduce what living organisms do,' says Rodríguez Navarro."

A young Spanish slug (Arion vulgaris) on a stinging nettle.

When it is warm and humid, this species will emerge in masses.

Roman snail (Helix pomatia)

The current spell of wet weather we have here is perfect for the snails.

Happy Monday Everyone!

🐌 At the end of last week Ark Wildlife Limited published a blog regarding the benefits of slugs and snails, written by Buglife Communications Officer, Nikki.

.@SymbiosisRox looking at bacterial #symbionts in the gill tissues of #HydrothermalVent #molluscs (across 6 sites) - these seemed to be structured with respect to vent site, and differences in gene content suggest local adaptation (e.g. to hydrogen concentration) #EESSymbiosis

What I thought were freshly laid apple/mystery snails seem to be something else that must've hitched a ride on plants.

Showing no signs of corkscrew in the shell, looking very planar. Maybe Ram's Horn? The one on the heater...

“Rottnest Island has suffered a "catastrophic decline" in #biodiversity. Despite being sanctuary zones with the highest level of protection from human activities, we found that Radar Reef and Cape Vlamingh at Rottnest Island had suffered a catastrophic decline in biodiversity between 2007 and 2021, likely due to exposure to the warm Leeuwin Current.”
