Algal Ecology: Freshwater Benthic Ecosystem by R. Jan Stevenson, Max L. Bothwell, Rex L. Lowe, James H.

By R. Jan Stevenson, Max L. Bothwell, Rex L. Lowe, James H. Thorp

I've got used this ebook rather a lot in the course of my MSc venture on Algal groups, that it turned my own bible for all elements of benthic algal ecology. it is a very complete ebook, that's either fascinating and suitable correct from the beginning until eventually the very finish. All themes are good designed and illustrated and all in all it's very great to learn - not just for Ecologists like me.

Introduction to Bryophytes

This is often an exceptional ebook for the undergraduate scholar drawn to studying approximately bryophytes. The chapters conceal the fundamentals, so when you are a grad pupil trying to brush up for basic tests, it is a nice publication for that goal.

Phytosociology of the Beech (Fagus) Forests in East Asia

This publication describes the mountain forests of East Asia (Korea, Japan, China and Taiwan), the tree layers of which comprise diverse species of the genus Fagus. The crops is basically deciduous within the northern areas, while in South China evergreen timber is additionally stumbled on: a complete of 21 plant groups are defined, with facts on species composition, dominance, geographical distribution and ecology.

Chemical Composition Chemical composition of benthic algal samples has been used as an indicator of nutrient availability for benthic algae and community health. Resource ratios, such as N:C, P:C, and N:P of algal samples, have been used to indicate cellular nutrient status (Biggs and Close, 1989; Biggs, 1995; Humphrey and Stevenson, 1992; Peterson and Stevenson, 1992). One important source of covariation in N:C and P:C ratios with nutrient concentrations in the water column is benthic algal biomass.
