Abstract Our study appears to represent the western-most report of autumn breeding within this species' range, the first report of potential environmental cues stimulating the occurrence of fall breeding, and the first examination of egg clutches and spermatogenesis from fall breeding populations. We conducted calling surveys throughout the year over a 4 year period extending from 1999–2002 to determine the frequency of fall breeding in this species. Southern Leopard Frogs bred 20 September… 

Reproductive variation corresponding to breeding season length in three tropical frog species

Data suggest that these widespread species have adapted to shortened breeding season length by increasing clutch size, which is associated with larger female size, but in the other two species female size is unchanged with respect to latitude.

Variation in Pond Hydroperiod Affects Larval Growth in Southern Leopard Frogs, Lithobates sphenocephalus

Effects of the drying/filling cycle varied over time on larval mass, but this cycle had no overall effect on other measures of larval or metamorph size.

Weather, hydroregime, and breeding effort influence juvenile recruitment of anurans: implications for climate change

The results indicate that weather and hydroregime characteristics interact with reproductive strategies that differ among amphibian species and influence reproductive plasticity, opportunity, and success.

The potential impact of simulated ground-water withdrawals on the oviposition, larval development, and metamorphosis of pond-breeding frogs

The estimated impacts of the simulations on the various life stages were the greatest for the Pine Barrens treefrog, and the 50-cm reductions shortening hydroperiods enough to practically eliminate the possibility of larval development and metamorphosis for all three species.

Female Reproductive Traits of the Southern Leopard Frog, Rana sphenocephala (Anura: Ranidae), from Arkansas

Reproductive characteristics of female southern leopard frogs (Rana sphenocephala) were studied from specimens collected in northeastern Arkansas and negative correlations were found between mean egg diameter and mass per egg as each varied with number of eggs per egg mass.

Diel activity patterns in the breeding migrations of winter-breeding anurans

Diel activity patterns in the breeding migrations of four winter-breeding anurans were examined at a breeding pond in South Carolina, U.S.A., using a terrestrial drift fence with pitfall traps, finding significant differences in migratory activity among time intervals, but no significant differences among time interval in either mean air temperature or rainfall.

Ecological shifts in the herpetofaunal of Lake Conway were caused by at least nine factors, grouped into four general categories: white amur, human disturbance, natural phenomena, unknown, and unknown.
