Episode 95: It's Been Haolong? — Tetrapod Zoology

 A year and a half of of catchup! TetZooCon regenerates into DinoCon , 20 years of TetZoo, Haolong , Spinosaurus (URG!) , and much more meandering and tangentiality.

Tetrapod Zoology
Abused by hard structures, the poor beach, denied Dynamic Equilibrium!!

> Tetrapods have become popular across the world, particularly in Japan. In 2007, it was estimated that up to 12 percent of Japan's 35,000-kilometer (22,000 mi) coastline was "semi-natural", defined as having been partially altered by roads or tetrapods. Their proliferation on the island of Okinawa, a popular vacation destination in Japan, has made it difficult for tourists to find unaltered beaches and shoreline, especially in the southern half of the island.

> Sandy beaches supported by man-made structures are more vulnerable to substantial beach area loss due to restricted landward migration, affecting ecosystem services. However, the global extent of ‘hardened’ sandy coastlines at risk of ‘severe beach loss’ has not been comprehensively quantified. Here, using products and geospatial datasets derived from satellite imagery, we find that, 33% of the world’s sandy coastline is currently hardened. Analysis of the results by IPCC AR6 regions show that the most hardened coastal regions are the Bay of Bengal, Western & Central Europe, the Mediterranean, Western North America, and East Asia. Linking coastal hardening information with existing shoreline retreat projections, we find that under SSP5-8.5, up to 26% of the world’s sandy coastline (~52,100 km) is likely to face severe beach loss by the end of the 21st century.

Variety of animals evolved similar genetics solutions to survive on land, study finds

Animals from completely different branches of the tree of life such as insects, worms and vertebrates independently evolved similar genetic solutions to survive on land, according to a new study from researchers at the University of Bristol and University of Barcelona.

Guess we doin #dichroic #tetrapods now...

Oh my! We may have overdone it a bit with the #HighVoltage at #Gaussfest

#SevereAlert #Tetrapods #TheyAreComing

Rounding out the week #3dprinting one of those #tetrapods I did the video about designing in @FreeCAD a few days back. #freecadfriday
Further to this mornings #tetrapod #tetrapods toot I've done a very quick n dirty @FreeCAD tutorial video on how to #CAD model one up... erm as an aside, tetrapod people, what do we call each limb of a tetrapod? Leg? Arm? Tooth? Who knows! Anyhoo here is the video on my @MakerTube

I blame @grajohnt for introducing me to people making #tetrapods and then seeing them all over the #why25 feeds... so naturally started my working week working out a @FreeCAD approach to laying one out! Might do a quick video later. #CAD #FreeCAD
