The temporal glands of African elephants were examined macroscopically and histologically, and were found to be modified apocrine sweat glands. The secretion from these glands was analyzed by gas chromatography and mass spectrometry, and some of the major volatile components have been identified as phenol andm- andp-cresol.

Constituents of temporal gland secretion of the African elephant,Loxodonta africana
Temporal gland secretion (TGS), obtained from 15 different mature African elephants in Kruger National Park was analyzed for volatile constituents, and three sesquiterpenes were identified, the latter two being new natural products.
Volatile compounds from the red deer (Cervus elaphus) Secretion from the tail gland
The major volatile, organic compounds secreted by the tail gland of the red deer (Cervus elaphus) have been identified as phenol,m-cresol, cyclohexanecarboxylic acid, benzoic acid, phenylacetic acid,
Putative Pheromone of the Indian Crestless Porcupine, Hystrix brachyura
Ethological data based on five porcupines, including both male and female in different combinations revealed that urine and feces are deposited non-randomly at specific sites.
Temporal gland secretion in African elephants (Loxodonta africana)
Using a hierarchical modeling approach that accounted for the nested data structure, it was found that TGS was mainly associated with elephant-specific variables, and the likelihood of TGS increased with elephant age, and females were more likely to show TGS than male elephants.
Special Relationships between Female Asian Elephants (Elephas maximus) in Zoological Gardens
The hypothesis that Asian elephant females may form special relationships was tested and confirmed and the removal of one member of a special relationship from the enclosure would elicit more arousal behaviour in the respective partner.

This review documents the published data on airborne (volatile) chemicals emitted from non-human animals, highlighting the subset of these emissions that play a role in guiding host choice by arthropod pests and provides a rationale for future enquiries.
Current understanding of lamprey chemosensory systems
This review summarizes current knowledge of the lamprey chemosensory systems, including stimuli, receptors, neural pathways and behavioural roles of the chemosensing stimuli, and supports the management of sea lamprey populations.
Central representation and projections of gustatory systems
The classical distinctions between olfaction and gustation in tetrapods, based upon the medium of stimulus delivery (air vs water) and the proximity of the stimulus source (distant vs contact) do not exist for aquatic vertebrates.
Vocal cues indicate level of arousal in infant African elephant roars.
Findings indicate that infant African elephant roars primarily function to signal the caller's arousal state, which may allow mothers to respond differentially based on their infant's degree of need and may be crucial for the survival of infant African elephants in their natural environment.

The findings are discussed with reference to the phylogenetic position of the genus, the probable role of the corpus luteum in pregnancy, and the significance of the results in relation to the conservation of existing wild elephant populations.
Comparison of sampling and extraction techniques for fatty acids in recent sediments
Abstract Saponification of recent sediment samples was the most efficient of several procedures tested for the extraction of fatty acids. Between 32 and 65 per cent of the fatty acids in the
This paper is based upon the teeth, body dimensions and weights of 58 male elephants ( Loxodonta africana ) collected in Uganda and represents an attempt to relate dental status to approximate age as

By chromatography on a silicic acid column, artificial lipid mixtures and plasma lipids have been separated into fractions composed mainly of the sterol esters, triglycerides, sterols, fatty acids and phospholipids.
