“…Five days later, at Gosner stage 25-26 (Gosner, 1960), they were introduced into the six ponds which contained no other anuran species due to the surrounding fences. The R. esculenta : R. lessonae-ratios among the released tadpoles were 0.71 for all ponds, but absolute numbers of tadpoles (2012-4024 ) were adjusted to pond water volume in order to achieve similar densities of 340 tadpoles/1000 l. This is well within the range of larval densities reported for many anuran species, including Rana (Cecil and Just, 1979;Morin, 1983). Higher densities can be found in shallow water (Petranka, 1989), but are not representative for the pond as a whole.…”

Abstract. Predictions about population and community dynamics are usually based on lab experiments. Because the results are dif cult to transfer to natural conditions, the major purpose of this study was to test the effects of biotic and abiotic factors on tadpole populations in a natural environment . We stocked six ponds, created the previous year, with known numbers of Rana esculenta and R. lessonae tadpoles and followed their developmen t over several months. When compared among ponds, tadpole density correlated positively with the nitrate:phosphat e ratio. This suggests that water chemistry may have affected survival, either directly or indirectly via productivity. Within ponds, both species showed a clear preference for the shallow zone. This behavior probably re ects a preference for warm water close to the surface, rather than avoidance of predators, because relative densities of odonates also increased from deep to shallow zones. This study is one of few that not only considers the distribution of the anuran tadpoles but the distribution of their predators as well.

“…The pattern of water depth partitioning among the members of the assemblage in this study could be affected by the differences in susceptibility of the tadpoles of different species of anurans to desiccation or predation (Cecil and Just 1979, Heyer et al 1975, Toft 1985, Wilbur 1980. The structure and dynamics of this tadpole assemblage do not appear to be affected by the desiccation factor, because the lake remains full for a much greater period than that required for the metamorphosis of all of the species (Vogt 1997).…”

“…Two lines of evidence argue against this possibility. First, overall survival in anuran larvae is usually quite low (often <10%o) in species without parental care (17)(18)(19). It thus seems unlikely that a large number of progeny would survive from any one mating.…”

A total of 305 individuals from a hybrid population of North American tree frogs was characterized for allozyme and mitochondrial DNA (mtDNA) genotype. Speciesspecific mating behaviors had suggested the potential for directional hybridization, in which matings between Hyla cinerea males and Hyla gratiosa females numerically predominate over the reciprocal combination. Such directional bias leads to predictions about expected distributions of the femaletransmitted mtDNA markers in F1, backcross, and latergeneration hybrids. These predictions were fully confirmed by the observed distributions of mtDNA genotypes among these allozymically inferred hybrid classes. Results exemplify the significance of stereotyped mating behaviors in determining the genetic architecture of a hybrid population.Rapid nucleotide-sequence evolution and maternal inheritance characterize the mitochondrial genomes of higher animals (1, 2). Thus, genetic markers provided by mitochondrial DNA (mtDNA) can facilitate determination of the female parentage of organisms in nature, a goal that has previously proved impossible to achieve from analyses of nuclear genes or their products. For example, Brown and Wright (3) used patterns of mtDNA restriction-site variation to show that the whiptail lizard Cnemidophorus tigris was the maternal parent for the parthenogenetic derivatives Cnemidophorus neomexicanus and Cnemidophorus tesselatus. mtDNA has been similarly applied to other hybridization systems involving sexually reproducing (4) and hybridogenetic (5) species.One potentially fruitful area for utilization of mtDNA data involves study of mating behaviors in hybrid zones where interspecific matings may be difficult to observe directly. Reproductive behaviors are often species specific and sufficiently stereotyped (26) to allow predictions on the direction of interspecific crosses. The major purpose of this investigation is to use genetic information to analyze mating behavior in a well-known hybrid population where mating bias has been proposed to exert an influence on direction of introgression.
