Hi high plains sailor, I find our PM system has a dreadful aspect...I did not notice it at first. Folks who send you a PM can actually delete their PM to you..after you received the PM..I do not like this feature of forum PM system! Charlie guevara

Re: Pater noster tractor ruts meiofauna and protists

Hi, redflanker..the hydras by habit...feed at or near waters surface...in less than 2.53 cm deep ditch/ rut waters. But I crudely scooped my collection samples..so I did not know where these hydras were living. Hydras are quite mobile..so they perhaps go to different areas of shallow ditch-waters..a...
