Canine scent detection: Lung cancer target acquisition
… over the last 30 years exploring disease scent detection using animals. Research project methodologies and results in this field vary significantly, including some which are quite promising. Critiques of aspects of current and past practice in disease scent detection using animals inform …

You smell : the mysterious science of scent
The sense of smell is a mystery-and the human sense of smell is a particularly inscrutable one. Only in the last 25 years have scientists identified the molecules in our noses responsible for detecting odors, and since then, the unexpected discovery of a new family of olfactory detection molecules …

A Scent of Direction: Exploring Adaptive Olfactory Navigation in Drosophila
<p>Animals rely on environmental cues, such as odors, to navigate through complex and often dynamic landscapes. While olfactory navigation has traditionally been modeled as a reflexive behavior driven by immediate sensory cues, whether flies can leverage more sophisticated strategies, integrating …

Strategic scent selection : an application of Zaltman Metaphor Elicitation Technique
… for the OLIVITA Artisan by finding specific scents that are closely aligned with its marketing strategy for their future product line, to reassure the existing brand image and increase its competency in the market. In order to find the scents that are aligned with OLIVITA Artisan's existing …

Canine scent detection: A new approach to detect invasive freshwater fish
… when fish are rare or elusive. Although scent-detection dogs have been used to detect a wide range of substances, diseases, and animals, there is limited information on dogs’ ability to detect aquatic species. This thesis aimed to determine if laboratory-based dogs could be used as a …

The pollination and scent ecology of selected Cape milkweeds (Apocynaceae: Asclepiadoideae)
… out in several sites across the Cape; floral scent samples were collected through headspace sampling and analysed using GC-MS (gas chromatography-mass spectrometry); floral colour was analysed using spectral reflectance measurements; and nectar was measured to quantify floral rewards. Some …

Territoriality and Scent Marking Behavior of African Wild Dogs in Northern Botswana
… on neighboring packs of wild dogs, and collected scent marks from known individuals for chemical analyses and behavioral experiments.</p> <p>To test whether wild dogs were territorial, I used VHF and GPS telemetry and direct observations. Wild dogs in northern Botswana exhibited territorial …

Scents and scent-sibilities: A sociocultural inquiry of smells in everyday life experiences
Here, smells take on a social character. Scents influence how we think, act and behave. The study argues for smell as a social intermediary that fleshes out issues concerning personhood and the presentation of self, and smells as employed in the (re)constructions of social boundaries running along …

A Scent-Station Survey of Medium-Size Mammals on the Callaway Preserve, Harris County, Georgia
… Preserve in Harris County, Georgia, using the scent- station technique, to determine species preference in regard to habitat, to compare relative abundance of species in regard to habitat, and to compare habitats in terms of the species present. Thirty-six scent-stations were established on the …

Taxonomical use of floral scent data in apomictic taxa of Hieracium and Sorbus derived from hybridization
Scent investigations are mainly carried out in the context of the ecological function of scent components for pollinator attraction, to study their geographical variability or their evolution. In contrast, profiles of inflorescence scent compounds were rarely used for phylogenetic analyses and …

The scent of a new world novel: translating the olfactory language of Faulkner and García Márquez
Both William Faulkner and Gabriel García Márquez introduce the olfactory as a focal element in their writing, producing works that challenge the singular primacy of sight as the unrivaled means by which the New World might be understood. As they translate experiences of the New World into language, …

Efficacy of Scent Dogs in Detecting Black-Footed Ferrets (Mustela nigripes) at a Reintroduction Site in South Dakota
… Study B the dogs were trained on live ferret scent in ferret habitat and then tested. The Final Field Test was an evaluation of the method after the dogs were adequately trained to detect ferrets in their natural environment, and after handlers were acclimated to working the dogs in those …

The use of a novel scent enrichment to improve captive primate welfare and its potential application to conservation breeding
Scent-marking behaviours are common across vertebrates, having roles in territoriality, sex identification and advertising fertility. Lemurs which rely on olfactory communication are a conservation priority and modern zoos have a role in contributing to their conservation with captive breeding …

Habituation, Scent-Trailing, and Effects of Temperature Upon the Strike-Induced Chemosensory Searching (SICS) in the Cottonmouth (Agkistrodon Piscivorus)
… that neonatal cottonmouths use conspecific scent trails to locate hibernacula using Y-maze experiments. Neonatal cottonmouths showed no preference for the odors of their mothers, conspecifics, or heterospecifics when paired with a control. This result suggests that neonatal cottonmouths at …

Importance of floral scent compounds for the interaction between Silene latifolia (Caryophyllaceae) and the nursery pollinator Hadena bicruris (Lepidoptera: Noctuidae)
… H. bicruris, which are attracted by the flower scent, pollinate S. latifolia. However, until now, nothing was known about the role of single flower scent compounds for the attraction of the moths. This thesis describes the chemical composition and the geographical variability in the flower scent …

Floral Scent in Salix L. and the Role of Olfactory and Visual Cues for Pollinator Attraction of Salix caprea L.
The chemical composition of floral scent of different Salix species as well as its inter- and intraspecific variability were analysed. The role of floral scent for attracting flower visitors was examined in S. caprea by means of electroantennographic studies and bioassays. The relevance of …
