Quadrat Sampling in Population Ecology

چکیده
Background Estimating the abundance of organisms. Ecology is often referred to as the "study of distribution and abundance". This being true, we would often like to know how many of a certain organism are in a certain place, or at a certain time. Information on the abundance of an organism, or group of organisms is fundamental to most questions in ecology. However, we can rarely do a complete census of the organisms in the area of interest because of limitations to time or research funds. Therefore, we usually have to estimate the abundance of organisms by sampling them, or counting a subset of the population of interest. For example, suppose you wanted to know how many slugs there were in the forests on Mt. Moosilauke. It would take a lifetime to count them all, but you could estimate their abundance by counting all the slugs in carefully chosen smaller areas on the mountain.

CMEIAS Quadrat Maker: A Digital Software Tool to Optimize Grid Dimensions and Produce Quadrat Images for Landscape Ecology Spatial Analysis
Quadrats are standard sampling units of relatively small, uniformly defined areas that divide a habitat of interest into subregions of equal size. They are used in ecography for 2-dimensional sampling of plants, slowmoving animals, and (more recently) microorganisms to (i) estimate population sizes when it is not feasible to measure their abundance in entirety, (ii) define the patterns of their...
متن کاملIllustrations and guidelines for selecting statistical methods for quantifying spatial pattern in ecological data
This paper aims to provide guidance to ecologists with limited experience in spatial analysis to help in their choice of techniques. It uses examples to compare methods of spatial analysis for ecological field data. A taxonomy of different data types is presented, including pointand area-referenced data, with and without attributes. Spatially and non-spatially explicit data are distinguished. T...
متن کاملEstimating plant population density: Time costs and sampling efficiencies for different sized and shaped quadrats
Given the increasing number of rare and listed plant species, and decreasing resources dedicated to monitoring such species, the need to implement powerful and efficient sampling designs has never been greater. Previous studies have examined statistical efficiencies of sampling designs; however, few studies have considered associated field efficiencies. We attempted to assess fairly the relativ...
متن کاملAn empirical probability model of detecting species at low densities.
False negatives, not detecting things that are actually present, are an important but understudied problem. False negatives are the result of our inability to perfectly detect species, especially those at low density such as endangered species or newly arriving introduced species. They reduce our ability to interpret presence-absence survey data and make sound management decisions (e.g., rapid ...
