This study lacks generalizability.
Generalizability is an academic term and describes the process of extending research findings and observations from a study on a sample population to a larger and more diverse population. The larger the sample population, the easier will be to generalize the results to the wider population. In this example, Dr Kirch used a sampling technique called convenience sampling, which involves the selection of the most available and proximate subjects. However, there is sampling bias since the sampling population is not representative of the entire population and therefore the study can not speak for the entire population.

Irina-Kira [14]

Answer:

They remain in an environment,even as more competitive species arrive

Explanation:

Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.

Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:

- They facilitate environmental change, making an environment more habitable for other species.

- They tolerate a wide range of environmental conditions.

- They are capable of colonizing a barren environment, as in primary succession.

However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
