Electrocardiographic param eters w ere determ ined fo r one o f the m ost endangered species in the w orld, the G om eran giant lizard, Gallotia bravoana, w ith a population o f only ten captive individuals in the world. H eart rate, rhythm , am plitude o f P, R, S and T w aves, interval o f RR, PR, Q T and ST w aves, duration of P, QRS, T waves, description o f SV w ave (representing depolarisation o f the sinus venosus), m ean electrical a x is , a n d c o r r e la tio n w ith c lo a c a l te m p e r a tu r e a n d w e ig h t w e re d e te r m in e d in th is p o p u la tio n. Electrocardiographic tracings showed a positive QRS com plex, presence o f an SV w ave, and T w aves occasion ally negative. Positive correlation w as observed betw een electrical axis and w eight, P duration and am bient tem perature, and S am plitude and cardiac frequency. N egative correlation w as observed betw een electrical axis and cloacal tem perature, S-T duration and the am bient tem perature, R-R interval and the cloacal tem perature, and R-R interval and cardiac frequency. This is the first com plete description o f the electrocardiographic para m eters o f a giant lizard o f Lacertidae fam ily and genus Gallotia.
In June 1999, a species of lizard previously considered extinct was rediscovered on the island of La Gomera, Spain. The giant gomeran lizard, Gallotia bravoana, is highly endangered and at risk of extinction by the feral cat population. A conservation effort to save the species was initiatived by the regional and central Spanish government and six lizards were captured and brought into captivity. This paper describes the results of the initial assessment of the health of the animals, by a physical examination and by haematological, biochemical, radiographical and coprological investigations. The methods used to maintain the animals in captivity are described and the first captive breeding success is reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
