Density Determination of Kinorhynchs

[Xymer]

Hi everyone!

I am currently working with the "Species composition, Density and
Distribution of Kinorhyncha in the Intertidal Zone of Naawan, Misamis
Oriental, Philippines" for my undergraduate thesis.

Do have you a PDF files of the International Biological Manual for
Meiofuana Extrapolation? or any other appropriate formula to determine
the density of meiofauna by using the Plexiglas tube?

Please help me regarding thing matter.

Thanks!

I am not familiar with the title you seek. Do you have the author and
the date of publication? If you are not already aware, I highly
recommend Higgins and Theil eds. (Introduction to the Study of
Meiofauna, 1988, Smithsonian Institution Press, Washington, D.C.) It was
revised and reprinted in 1992 but is not available as a PDF. As the
title implies it covers nearly all aspects of Meiofaunal research.

Thanks for the response. Fortunely, Dr. John Fleeger already emailed
me about what I need.

God Bless and More Power!

Best,
Xymer

I'm always interested in this group. If possible, could you share the information he gave you? I'm particularly interested in literature and techniques in Kinorhynch taxonomy.

He taught me on how to get the density of the kinorhynchs by using the
Plexi glass tube or improvised corer.

By measuring the inner diameter of the corer using the caliper then
dividing it by 2 to get its radius. Thus,

r = diameter / 2

Then, using the formula of the cirle to get the area or surface area
of the corer:

A = pi*r2 (radius squared)

And as for data standardization of Higgins and Thiel (1988) the
standard surface area of the corer which is 10 cm2 will be used to
facilitate comparisons between studies using different sampling
techniques.

You just need to convert the area by proportionality to a density in a
standard unit (10cm2).

By the way, number of individuals per 10 cm2 to get its final density.
