Snail populations were monitored during 42 consecutive months in three types of habitats (ephemeral pond, ephemeral river and permanent stream) in two sites covering different climatic zones in ...

A quadrat sampling method for conducting aerial census of moose (Alces americana) that is adapted to extensive units of habitat was developed and applied in two areas of Alaska. This report describes ...

Random sampling is an important approach to field vegetation surveys. However, sampling surveys in desert areas are difficult because determining an appropriate quadrat size that represent the sparse ...

Abstract: Forest vertical structure is critical to ecological function, and provides a crucial link to air- and spaceborne remote sensing (including LiDAR), but is difficult to measure from the ground ...

These are placed on the ground to look at the plants or slow-moving animals within them. When looking at plants in a quadrat, the following sampling can be used: Random close randomOccurring without a ...

When sampling a population, the numbers of organisms are counted within a sample site, and then the results multiplied to estimate the total number in the entire habitat. Large animals and plants can ...

Students in the Marine Biology Practicum class (FNR 378000) spent 11 days before the fall semester began, gaining hands-on training at the Seahorse Key Marine Lab in Florida. The trip allows students ...
