Résumé:
The Anurans constitute an order of animals belonging to the Amphibia class, which
includes frogs and descendants, in Brazil is the world's largest biodiversity of these
organisms, species of the Leptodactylidae family play an important role in their habitats
and are considered as bioindicators because provide information on possible ecosystem
disturbances. These animals occur frequently in areas of the caatinga domain where the
rainfall pattern determines the energetic activity as well as the reproduction of these
individuals, whereas these species present a great variety of physiological and ecological
strategies during the periods of drought. Through this the information presented in this
research seeks to show how seasonality interferes in energy metabolism, and
consequently in the reproductive processes of these animals. The material used in the
research was collected in the the Horto Florestal Olho D’água da Bica (HFODB) in the
municipality of Cuité-PB, adult males of the species L. macrosternum were collected
biweekly between January and December 2013. For the accomplishment of the
experiment, small fragments of the testicles were removed, weighed and measured, which
later were sent to the histological routine, in the analyzes of the material it was observed
the presence of different cell types. The protein and carbohydrate quantifications were
statistically analyzed, the monthly values of the protein amounts presented the highest
mean value in July, while the carbohydrates presented the highest levels of carbohydrates
in June, July, August, September and December with the highest values average values,
and the month of May with the lowest value. There were only significant relationships
between rainfall and temperature with carbohydrate amounts, and no significant
relationship with the amounts of proteins deposited in the L. macrosternum testis.
