In many cases, it is not even possible to count signs of every member of a population. The population may be very large or spread over a wide area. In such cases ecologists usually make an estimate. An estimate is an approximation of number, based on reasonable assumptions.

Sampling gives good insight of the choosen sample
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.

Sampling is important in field ecology because it allows researchers to collect data that is representative of the entire population or ecosystem they are studying. By sampling a subset of the population, researchers can make conclusions and generalizations about the entire population. Sampling also helps to minimize bias and ensures that the data collected is reliable and accurate.
By taking a sample of the entire population.
Ecologists are concerned with the use of mathematical models and systems analysis for the description of ecological processes and for the sustainable management of resources!
Ecologists from around the globe met to discuss the effects of global warming on plant life.
I am an ecologist.Ecologists can make a better envirment.
Sampling up an image is the same with enlarging it. You can use up sampling to fit an image to a larger surface.
make predictions about the future behavior of an ecosystem!
