AbstractThe amphibian fauna of Sichuan Province, China, is remarkable for the large number of species of pelobatid frogs, of which species of Oreolalax form a large portion. We have collected larvae of five species of Oreolalax on Mt. Emei, Sichuan, four of these five at a second locality 40 km from Mt. Emei, and larvae of two additional species at a locality 200 km S of Mt. Emei. These tadpoles are very similar to one another morphologically, a conclusion supported by multivariate analysis. We give diagnostic descriptions and a key for the identification of these seven larval forms. All tadpoles of Oreolalax have lotic habits, and the seven species in our study live in small to medium-sized streams (maximum width 8 m). These species show only moderate ecological segregation in terms of stream size and microhabitat type.

Abstract The choice of breeding sites by pond-breeding anurans has notable consequences for the fitness of larvae. Hence, beyond pond typology and phenology, adults can also discriminate according to several other features, for instance to favour allotopy with potential competitors. However, the lack of shared evolutionary history might impede proper ecological differentiation with alien species during the first stages of invasions. Here, we studied several possible sources of ecological segregation between the invasive Discoglossus pictus and the native Epidalea calamita in ephemeral ponds, where the native toad hardly had competition before the arrival of the invasive frog. During spring of 2016, we periodically surveyed 69 ephemeral ponds in three areas with different invasion histories to detect the presence/absence of eggs and tadpoles of these species. Invasive D. pictus started breeding earlier than E. calamita, but differences were not significant. Similarly, there were not clear differences among areas with different invasion histories. However, we found for both species a mutual tendency to directly avoid larval syntopy at the end of the reproductive season. We also found interspecific differences in the features that both species use for pond choice, preferring the native species shallower and less vegetated ephemeral ponds. Globally however, co-occurrence was high, pointing at other processes as key to the coexistence between both species in these habitats.
