Re: Aspidisca walking and swimming

Thanks mazo for these observation vids. All these hypotritch ciliates can be enjoyed to the point of a specialty niche ..so much complexity in these plentiful and important protists in aquatic assemblages. Hypotrich ciliates are 'heavy lifters' in freshwater and marine recycling of nutrients from ba...

Re: Nikon Plan Apo Lambda 20x - ok??

I came to this thread very late...hi all. I sense that when you 'drop duckets' for costly optics...it's good to keep to one brand of stand...to 'mix and match' hinders later selling of a cobbled together stand. One takes many paths with microscopy..if a goal is better resolution and enhanced image c...
