fractions made up 7.7-25.4% (>20 [micro]m) and 3.3-19.7% (<20 [micro]m) of total SOC in soil, and the oPOM fractions 3.4-11% (>20 [micro]m) and 3.4--11% respectively.
It suggests that artificial leaves may be used as substrate or refuge for these macroinvertebrates and their food may be obtained from the FPOM
, the water column, and biofilm attached on it.
showed the same trend within two of the three rivers.
Inorganic carbonates were removed from shrimp, crabs, FPOM
, and CPOM through treatment with minute quantities of IN hydrochloric acid until the reaction ceased (Jacob et al., 2005).
Uno de ellos es el modelo de los Flujos de Fondos Borrosos (FFB) o Fuzzy Pay-Off Method (FPOM
), Collan; Fuller y Mezei (2009.) En este se utiliza la logica borrosa y los numeros triangulares para valuar opciones reales (VOR) incorporando la tecnica de escenarios.

Leaf litter, periphyton and FPOM
samples were placed in a desiccator with a beaker containing 100 ml hydrochloric acid for 6 h to remove inorganic carbonates.
the fine fPOM
, was aspirated and filtered on a pre-weighed 20-[micro]m nylon filter.
Most noticeable among these differences were the chironomid fecal pellet values, lower relative amount of FPOM
, and greater proportion of particles >250 [micro]m in size.
Hoffman A (2005) Dynamics of fine particulate organic matter (FPOM
) and macroinvertebrates in natural and artificial leaf packs.
Detritivores held in artificial streamside channels were food limited (Richardson 1991), and higher levels of coarse particulate organic matter (CPOM) loading resulted in higher densities of collectors feeding on fine particulate organic matter (FPOM
, Richardson and Neill 1991).
Results show that atyid and Xiphocaris shrimps significantly affect the quality and quantity of fine particulate organic matter (FPOM
) in streams where they are abundant.
