Fluorometric estimation of surface associated microbial abundance

Journal of Microbiological Methods, 2012
Surface associated microbes have historically been difficult to accurately and effectively enumerate. In the current study, we propose a rapid and simple method for estimating abundance of surface associated microbial cells by fluorescence of SYBRGreen stained bacteria and in vivo chlorophyll a fluorescence of benthic diatoms in 24 and 48-well ...

Estimating the Abundance of Adults and Immatures

1991
At the single field or farm level, pest managers who consider how Heliothis spp. affect their crops need current information on Heliothis numbers on which to base management decisions and assess the efficacy of past control tactics (Wilson and Room, 1982).

Estimating the abundance of breeding Snipe

Bird Study, 1985
It has been asserted previously that spring counts of drumming Snipe over-estimate breeding population size. Yet the present study reveals that the reverse is true.

Estimating the abundance and diversity of butterflies

Biological Conservation, 1975
Abstract Concern about the apparent decline in butterfly populations has led to projects designed to obtain quantitative information on their abundance and diversity. Three methods of sampling communities of butterflies are suggested, and the use of a diversity index, β, is recommended.

Introduction to Estimating Wildlife Abundance

2001
Estimating animal abundance is central to sound management and is an important part of most wildlife research programs. Counting animals is a challenging task that will take you to many fascinating places that you would not otherwise see. I myself have spent many years in the bush trying to figure out how many animals were in my survey areas, and I ...
