“…Saraiva et al [138] used GC×GC-TOFMS in an ecological study to differentiate three mammal species through the volatiles released by their scats. The technique proved to be useful for wildlife species management as it was possible to distinguish and get information regarding the dietary habits of the studied animals through their scat volatile profiles.…”

Multidimensional approaches in gas chromatography have been established as potent tools to (almost) attain fully resolved analyses. Flavours and odours are important application fields for these techniques since they include complex matrices, and are of interest for both scientific study and to consumers. This article is a review of the main research studies in the above theme, discussing the achievements and challenges that demonstrate a maturing of analytical separation technology.

“…2003; Saraiva et al . 2014). However, the diversity, potential species discrimination, and ecological functions of other metabolites in the Carnivora are still unexplored, particularly non‐volatile compounds (NVOCs), which are more stable to environmental adversity (Alberts 1992).…”

“…The detection of chemical compounds in fecal samples is a potentially effective and non-invasive method to investigate the presence of medium and large mammal species in natural environments, species identification (Araujo et al 2010;Saraiva et al 2014) andchemical communication between individuals (Weiß et al 2017). These alternative tools are relevant because many medium-to large-bodied mammals, particularly of the Carnivora, are often difficult to observe and capture in the wild.…”

“…A significant chemical diversity of volatile compounds (VOCs) has already been identified in carnivore fecal samples; these include heterocyclic aromatic organic compounds, carboxylic acid, steroids, and pheromones (Martín et al 2010;Kean et al 2011;Miyazaki et al 2018). The diversity and specificity of those chemical profiles have allowed for interspecific, intersexual, and individual discrimination in several taxa (Zhang et al 2003;Saraiva et al 2014). However, the diversity, potential species discrimination, and ecological functions of other metabolites in the Carnivora are still unexplored, particularly non-volatile compounds (NVOCs), which are more stable to environmental adversity (Alberts 1992).…”

Neotropical mustelids: fecal metabolome diversity and its potential for taxonomic discrimination

et al. 2022

Chemical profiles of non‐invasive biological material, such as feces, have great potential to study elusive animals or those with low population densities. Here, we use a metabolomic approach to evaluate Neotropical mustelids as a biological model to describe the diversity of the metabolites present in fecal samples, as well as to evaluate the potential of chemical profiles for taxonomic discrimination. We collected fecal samples from captive individuals of 5 species of mustelids occurring in Brazil and analyzed them by liquid chromatography coupled to high‐resolution mass spectrometry. Over 200 compounds have been annotated; “bile acids, alcohols and derivatives” was the most expressive class in the metabolome of all the species. We successfully discriminated 3 taxonomic groups: 1—tayra (Eira barbara); 2—otters (Lontra longicaudis and Pteronura brasiliensis; 1); and 3—grisons (Galictis vittata and Galictis cuja). Several compounds seemed to be associated with food intake and the digestive process, while others were found for the first time in Neotropical mustelids. We concluded that mustelids show high metabolome diversity and that species‐specific identification through metabolomic profiles is possible, thus contributing to the development and implementation of additional non‐invasive approaches in the study of mustelids.

The mutualism between chemical cues emitted into the air and variations in how primates respond to them using olfaction has demonstrated aspects of species‐specific adaptations. Building on this mutualism we can look at particle deposition as another means to understanding how various environments may have elicited biological changes that enable efficient communication. Research on particle movement and deposition within the nasal cavity is largely based on questions about health as it relates to drug delivery systems and overall olfactory function in modern humans. With increased access to 3D models and the use of computational fluid dynamic analysis, researchers have been able to simulate site‐specific deposition, to determine what particles are making it through the nasal cavity to the main olfactory epithelium, which ultimately leads to processing in the olfactory bulb. Here we discuss particle deposition research, sensory drive and their potential applications to evolutionary anthropology.
