Yara Gambirasio The story of the poor has come to life, in terms of disinformation dog, a new subject: the "molecular dog." Called once
pistaiole , this dog is actually a Bloodhound - Dog blood trail - Group 6 ENCI Section 1.1 - used since the seventh century as a hunting hound in (ungulates injured). For its construction
morphological and functional is a subject with great strength and an extraordinary sense of smell (thanks to the prismatic construction of the skull, the sinuses under-developed, divergent lines of the head and facial profile slightly arched) doti che gli permettono di seguire senza sforzo una pista su lunghe distanze e attraverso terreni accidentati.
Cane in grado di ricoprire più terreno in assoluto rispetto a tutti gli altri segugi, fu utilizzato in America per la ricerca degli schiavi feriti e dei galeotti evasi, in virtù della sua proverbiale ostinazione e tenacia; dote tipica di tutti i segugi.
La moderna comunicazione mediatica, però, ci ha improvvisamente abituato – in modo discutibile - ad associarlo ad un improbabile invenzione moderna con l'appellativo, appunto, di “ cane molecolare ”.
Ma perché il Bloodhound – chiamato più correttamente “ Chien de Saint Hubert "- has been defined in this way, beyond" wow effect "that necessitates the TV, doing such damage to the breed to see me get daily e-mail that asks for addresses of specific holdings of" molecular dogs ?
From what does this term?
E 'inappropriate?
to respond seriously to this question must first understand how it is structured the nose of a bloodhound (like any other dog), his motivational triggers related to predation and a specific study on the research technically called "a megaolfatto - or "microsfron" (different from the research "to teleolfatto - also known as "teleosfron).
As biologists know, the chemical components called "molecular " have a higher specific gravity and are deposited on the ground, leaving a trail for Bloodhound is particularly interesting to the point where, thanks to the pendulous ears that allow him to work in "One Track Mind " very high percentage of resources to concentrate without distractions olfactory exploration may in any way interfere in the search. On
pendulous ears, however, is worth remembering - to better understand this peculiarity - that have been selected so especially for conveying important odors (those covered by the research) to the nose and not allow it to mix with those carried by the wind.
In hunting, however, these chemical traces are really fresh and, above all, mixed.
the blood of the prey are mixed microbial fermentation processes trampled soil, saliva of the animal injured, his sweat, any dung: a highway of odors that lead to the Bloodhound target with surgical precision.
However, if this is true of the "Chien de Saint Hubert ", the same applies to all hunting dogs, although percentage of energy invested - and in particular ways - different.
As I mentioned earlier, the "megaolfatto" and "teleolfatto" differences assume that every dog \u200b\u200blover knows well: while the search in "megaolfatto shall be effected consistently with his nose to the ground, as in" teleolfatto is telescopic, ie able to assess the presence and position of particles from afar, not from inhaling the track where the prey has passed (or person), but sucking wind that is suspended in minute quantities.
Undoubtedly this type of research needs of dog whose conformation of the skull provides extensive frontal sinuses and nasal bridge straight, even pointing upwards as in the case of the Pointer.
Aces skull facciali saranno paralleli e convergenti e tutto ciò permetterà, a seguito di profonde e rarefatte inspirazioni dell’aria, di incamerarne molta a livello dei seni nasali e incanalare una quota sufficiente di particelle che verranno poi concentrate e trasformate in stimoli elettrici.
In questo modo il cane si addentra nel cono d’odore che diventerà sempre più ristretto e intenso all’approssimarsi dello stesso all'obbiettivo della ricerca.
Per concludere, il “ cane molecolare ” è in realtà una suggestiva didascalia televisiva del “ Chien de Saint Hubert ”, e non una razza creata ad hoc da qualche scienziato moderno.
A parte questo, trovo sconcertante - As dogs and perilous part of the city "by Rescue Dog Units Boat" (and thus attributed to the Civil Protection of Regione Marche) - the expectation unjustified proposal through the media about this dog. Through improper
label (for the general public) of "molecular dog" has a wonderful oversized first race without explaining what this actually is and then later discredit the volunteers who tried to find traces of the poor Yara.
Any thought or opinion on, as always, I leave it to readers.
