USE OF NEMATODE DESTROYING FUNGI AS INDICATORS OF LAND DISTURBANCE IN TAITA TAVETA, KENYA
Tropical and Subtropical Agroecosystems, 2009 This study was undertaken to determine whether nematode destroying fungi can be used as indicators of soil disturbances. Soil samples were collected from an indigenous forest, maize/bean, napier grass, shrub and vegetable fields, which represented the ...

Day-to-day dynamics of commensal Escherichia coli in Zimbabwean cows evidence temporal fluctuations within a host-specific population structure [PDF]
, 2017 To get insights into the temporal pattern of commensal Escherichia coli populations, we sampled the feces of four healthy cows from the same herd in the Hwange District of Zimbabwe daily over 25 days. The cows had not received antibiotic treatment during

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

A program for statistic test of community evenness [PDF]
Computational Ecology and Software, 2012 A Java program to statistically test community evenness was developed in this study. In the algorithm the community diversity was represented by Shaanon-Wiener index, and Ewens-Caswell neutrality model was used to test community evenness.

Determining trophic niche width: a novel approach using stable isotope analysis [PDF]
, 2004 1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.
