Ecological studies are particularly useful for generating hypotheses since they can use existing data sets and rapidly test the hypothesis. The advantages of the ecological studies include the large number of people that can be included in the study and the large number of risk-modifying factors that can be examined. [citation needed]
The Long Term Ecological Research (LTER) Network consists of a group of over 1800 scientists and students studying ecological processes over extended temporal and spatial scales. Twenty-eight LTER sites cover a diverse set of ecosystems. It is part of the International Long Term Ecological Research Network (ILTER). [1]
Data collected from these experiments is used to draw conclusions about ecological processes, patterns, and underlying mechanisms. Experimental ecology is a new methodology in ecological research, formalized by Henrik Lundegårdh [1] in his 1925 book, Klima und Boden. As stated above, Experimental ecology is a branch of ecology that focuses on ...
Community ecology is the study of the interactions among a collection of species that inhabit the same geographic area. Community ecologists study the determinants of patterns and processes for two or more interacting species. Research in community ecology might measure species diversity in grasslands in relation to soil fertility. It might ...
Human values, wealth, life-styles, resource use, and waste, etc. must affect and be affected by the physical and biotic environments along urban-rural gradients. The nature of these interactions is a legitimate ecological research topic and one of increasing importance. [16]: 1233
Ecological genetics is the study of genetics in natural populations. It combines ecology, evolution, and genetics to understand the processes behind adaptation. [ 1 ] It is virtually synonymous with the field of molecular ecology .
Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence.

Ecological validity, the ability to generalize study findings to the real world, is a subcategory of external validity. [ 6 ] Another example highlighting the differences between these terms is from an experiment that studied pointing [ 7 ] —a trait originally attributed uniquely to humans—in captive chimpanzees.
