“…Using a range of microscopic techniques, the features of hair (fiber's diameter, shape and size of the scales of the cuticle, presence of medulla and its pattern) are recorded, although some authors have debated the diagnostic value of the cuticular pattern . Microscopy has been used in forensics, illegal trade, textile research, and conservation and archaeology for species identification. The task is however painstaking and requires intense expertise and experience, as well as a large bank of references to train the eye to inter‐ and intra‐species variations .…”

“…They were able to distinguish between species based on discriminant function analysis. Similarly, Sahajpal et al used discriminant function analysis to characterize hair from four mongoose species of India, based on the banding pattern of the hair [21]. Sahajpal et al further reported the guard hair characteristics of four Indian bear species and bovid species listed under Schedule I of Wildlife (Protection) Act 1972 of India [22,23].…”

Illegal wildlife trade is one of the biggest threats to the environment and biodiversity. The growing volume of illegal trade in wildlife jeopardizes all the conservation efforts across the globe. Many species have become extinct due to the illegal wildlife trade and many have reached the verge of extinction. According to some estimates, the monetary values of the illegal wildlife trade are estimated to be several billion US dollars. To deal with wildlife crime cases, it becomes imperative to have a sound knowledge of the techniques required in the analysis of wildlife crime exhibits. In this chapter, we have outlined the three frequently used techniques in wildlife forensics viz. microscopy, DNA and isotope analysis for addressing the problems of species and individual identification, and additionally identification of the geographical origin of a wildlife sample. The basic essentials of these techniques have been discussed in this chapter.

“…A scanning electron microscopy (SEM) study on cuticular pattern of guard hair of Tibetan antelope ( Pantholops hodgsoni ) was carried out by Bahuguna and Mukherjee[ 35 ] for species characterization from a forensic view point. Sahajpal & Goyal[ 36 ‐ 39 ] highlighted the usefulness of the microscopic hair characteristics for species identification for dealing wildlife offence cases in India. Sahajpal et al [ 39 ] reported the guard hair characteristics of four Indian bear species and mongoose species for species identification and dealing poaching cases related to bears and mongooses.…”

With regard to studies on keratin patterns for species characterization in India, only one study has been reported on electrophoretic characterization of keratins by Sahajpal and Goyal,[ 37 ] which deals with use of SDS-PAGE to identify Shahoosh ( Pantholops hodgsoni ), Pashmina ( Capra hircus ), and Angora ( Oryctolagus cunniculus ).…”

India is known for its rich biodiversity, with a wide variety of wild floral and faunal species. This wildlife treasure of ours faces the threat of extinction due to rampant poaching and illegal trade. With most of the wildlife offence cases related to mammals having hair as physical evidence, it becomes imperative to use this evidence in the best possible way for wildlife crime investigation. We discuss the value of hair evidence with special reference to species characterization/identification using microscopic hair characteristics, keratin patterns, and mitochondrial DNA typing. The relevance of the techniques with respect to Indian scenario is specially taken care of and microscopic hair characteristics of one of the highly endangered species along with its keratin pattern are described. Finally, the use of mitochondrial DNA for species identification is also discussed.
