“…Thus, one should expect some variability between species and relative uniformity within them (Caldara & Leite, 2012; Silveira, Sbalqueiro, & Monteiro, 2013). Studies have shown that hair features such as the cuticle, the medulla, the cortex, hair diameter, the colour and length can be used to differentiate between species (Caldara & Leite, 2012; Cavia et al., 2008; De Marinis & Asprea, 2006; Duarte & Lessa, 2015; Lee et al., 2014; Silveira et al., 2013; Teerink, 2003; Wade, Stokes, & Spencer, 2018). As a result, several systematic hair identification keys were established to distinguish between mammal species belonging to orders such as Rodentia, Lagomomorpha, Carnivora, Artiodactyla, Inserctivora and Chiroptera (Keogh, 1985; Lee et al., 2014).…”
