In this thesis, different characteristics of the hair coat of the Lutrinae were investigated: - variability of the primary hair structure in the Eurasian otter (Lutra lutra) - hair structure of the 13 otter species - hair density of the Eurasian otter (Lutra lutra) and the Sea otter (Enhydra lutris) Also, the regulation of heat loss through the surface of the body was studied using an infrared thermographic camera. 

A Note on the Specific Cuticle Structure of Wool Hairs in Otters (Lutrinae)

The cuticle structure of the wool hairs (secondary hairs) of six otter species was examined by scanning electron microscopy to clarify the specific function of this hair type in the Lutrinae. The

Comparative hair structure in the Lutrinae (Carnivora: Mustelidae)

The macroscopic and microscopic hair structure in the Lutrinae has been influenced by both phylogenetic relationships and adaptive pressures, and an influence of the climate and of the association to water could be recognized.

Hair density in the Eurasian otter Lutra lutra and the Sea otter Enhydra lutris

The hair density of adult Eurasian otters Lutra lutra and sea otters Enhydra lutris was analysed using skin samples taken from frozen carcasses, finding no influence of the sex, nor a seasonal variation of the hair coat was found, moulting seems to be continuous.

Basic structural and functional characteristics of the epidermal barrier in wild mammals living in different habitats and climates

Densitometric evaluation of the 5-hexadecanoylaminofluorescein staining revealed that reaction intensity was not only generally related to the habitat conditions but also to vital epidermis thickness and hair density, as in the hippopotamus or the cetaceans.

Infrared thermography of the body surface in the Eurasian otter Lutra lutra and the giant otter Pteronura brasiliensis.

The body surface temperatures of the Eurasian otter Lutra lutra and the tropical giant otter Pteronura brasiliensis were studied based on detailed infrared thermography and a specific heating of sensory organs on the head could be observed.

Thricology for identifying mammal species and breeds: its use in research and agriculture.

Trichology is an important tool for local breed studies in Brazil considering that characterization may help elucidate characteristics such as hardiness, prolificity, resistance, that warrant conservation and breeding efforts of local breeds.

NOTE ON HAIR-SAMPLING DEVICES FOR EURASIAN OTTERS

Devices to collect hairs from Eurasian otters were tested in captivity. Two designs of hair traps (a wooden box and a set of 7 sticks stuck into the ground) were set in an enclosure and each was

Aquatic adaptation and depleted diversity: a deep dive into the genomes of the sea otter and giant otter.

Despite its recent invasion into the marine realm, the sea otter (Enhydra lutris) has evolved a suite of adaptations for life in cold coastal waters, including limb modifications and dense insulating

Remarks on specific adaptive scale structure of the hair cuticle in some European bats.

Specific regional variation of scale structure of the hair cuticle was demonstrated by scanning electron microscopy in five vespertilionid bat species, and could be explained as an adaptive help to maintain a turbulent boundary layer of air around the body to aid hovering or gliding flight.

Differentiating hair samples of the European mink (Mustela lutreola), the American mink (Mustela vison) and the European polecat (Mustela putorius) using light microscopy

A method is described for the identification of European mink hair by light microscopy, and its differentiation, on the basis of cuticular and medullary patterns of guard hairs, from hairs of similar mustelids, the introduced American mink Mustela vison and the European polecat Mustela putorius.

Structural Characteristics of the Hair of Mammals

The present paper aims to be an answer to numerous inquiries regarding: (1) the structure of a large number of maummal hairs, with especial reference to the possibility of systematically classifying them upon some morphologically accurate basis; (22) the relationships between the various elemental structures of the hair shaft; and (3) the methods employed in the preparation of the hairs for microscopic analysis.

Identification of hair and feather remains in the gut and faeces of stoats and weasels

Qualitative analysis of the gut and faeces contents of stoates and weasels is complicated by the lack of readily identifiable bone fragments, teeth, feathers, etc., of mammalian or avian prey, so a key to the main bird orders was devised.
