Wildlife endocrinology

Wildlife endocrinology can help understand the mechanisms by which organisms cope with changing environment and therefore plays an important role in wildlife conservation. Field endocrine strategies have progressed quickly as of late and can give considerable data on the growth, stress, and reproductive status of individual creatures, in this manner giving knowledge into current and future reactions of populations to changes in the earth.[3] Ecological stressors and regenerative status can be recognized nonlethally by estimating various endocrine-related endpoints, like steroids for plasma, living and nonliving tissue, urine, and feces.[4] Data on the natural or endocrine necessities of individual species for typical development, advancement, and multiplication will give basic data to species and environment preservation. For some taxa, essential data on endocrinology is missing, and progress in preservation endocrinology will require approaches that are both "fundamental" and "applied" and incorporate reconciliation of research center and field approaches.[3]

Sampling always depends upon the feasibility of the sampling protocol. If one is assessing the health of humans or captive, based on what kind of information one is seeking, sampling can change.[5] In case of animals, it is easier to conduct blood sampling or collection of tissues from captive animals. Here one needs to be in closer contact with the target individual. But when working with wild animals, this might not be possible and thus other methods of sampling such as non-invasive sampling can be done.[6] On the basis of invasiveness, there are two types of sampling.
