Re: Pater noster tractor ruts meiofauna and protists

Notable to me from circa 1950 textbooks, desmids indeed flourish on open moist soils...I enjoyed these brilliant crop field desmids, please enjoy these with me. Ah yes, a large ciliate, 'new to me' encountered in these tractor ruts. Plenty of time, now that I imaged captured these ciliates, to 'look...

Re: Pater noster tractor ruts meiofauna and protists

Both these finger-nail clams and copepods...active in October'19 suggest these hardy meiofauna flourish/thrive year round if liquid waters are in their habitat.

Re: Pater noster tractor ruts meiofauna and protists

Hi 75RR, this specific area of the deep sloped cropfield always seeps surface waters down to the drainage channel at bottom of this land...the bottom I guess is termed the 'valley floor'. In dead of winter with weeks/month or so of below freezing temps...there is liquid water under thick ice cover o...

Re: Pater noster tractor ruts meiofauna and protists

Prior to this years chance tractor rutting, this specific area of vernal surface water flow down slope to the valley bottom drainage area was always a seep of less than one inch (? 2.53 cm?) depth...a near 'film of surface waters' which never hosted the field markers of rich meiofauna and protists. ...

Costal mudflats/shore areas host fantastic diatom communities. Leave collection plastic bottles 3/4ths submerged in shore waters...diatoms literally climb into the collection bottles.
