“…Thus, although males began vocalizing early, reproduction, based on the presence of early stage tadpoles, did not occur until hydrological conditions of wetlands were appropriate for larval development (Lowe et al 2015). The flexible reproductive strategies of L. olongburensis are consistent with adaptations to temporary and unpredictable breeding habitats and are requirements for improving reproductive success rates in the wild (Wilbur 1987;Jakob et al 2003;Richter-Boix et al 2006;Vignoli et al 2007;Lowe et al 2015). Temperature and rainfall are often the most important factors controlling the timing and duration of amphibian breeding cycles (Duellman & Trueb 1994;Richter et al 2003;Eikenaar et al 2012).…”

“…This long calling season may increase their chance of capturing the rainfall peak within that window, which for the study area can occur any time from late spring to early autumn (Chiew & McMahon 2002;Griffith et al 2008). Indeed, calling peaks were highly responsive to peaks in rainfall, which, together with the long calling season duration, are adaptive response to climatic unpredictability and temporary wetland breeding (Wilbur 1987;Jakob et al 2003;Richter-Boix et al 2006;Vignoli et al 2007;Lowe et al 2015). Populations in southern latitudes had a shorter calling season compared with populations in northern latitudes, a trend also evident in some Australian frog species in New South Wales (Lemckert & Mahony 2008).…”

Amphibian reproductive biology and activity are highly sensitive to environmental cues. For amphibian conservation in the face of climate change, a clear priority is to investigate impacts of variable weather on breeding activity and detectability. This study assessed variation in the phenology, intensity and detectability of calling for a threatened temporary wetland breeding species, Litoria olongburensis. Acoustic and visual surveys were conducted monthly from August 2009 to July 2011 over the species latitudinal range in eastern Australia. Calling phenology of L. olongburensis varied spatially and temporally within and among latitudinal clusters. Detectability of frogs also varied among months and transects, and also with the type of survey conducted (visual vs. acoustic). Air temperature was a strong predictor for the onset of the calling season (early spring); however, peaks in calling abundances were primarily driven by monthly accumulated rainfall. The duration of the calling season varied among latitudinal clusters, becoming narrower moving south, reflecting clinal variation in weather patterns. This study presents a framework for amphibian species management using a combination of survey techniques and the climatic conditions influencing detectability. Applied along the latitudinal gradient, it provides data for predicting the likely impacts of climate change on amphibian activity and reproduction.

“…The implications of these findings are that at the scale of a habitat or pond, differential abiotic and biotic conditions contribute to species diversity in an area (Alford & Wilbur 1985;Lawler & Morin 1993;Vignoli et al 2007;Indermaur et al 2010).…”

Sympatry of species has been a central debate in ecology for decades but the mechanisms that allow coexistence are still heatedly disputed. The main paradigms include the importance of abiotic conditions, predation risk, and competition as determinants of community structure. In this study, we investigated oviposition-site selection of two anuran species, Asiatic toads (Bufo gargarizans) and dark-spotted frogs (Pelophylax nigromaculata), which coexist in southwestern China. We sampled the abiotic and biotic attributes of 36 B. gargarizans breeding sites and 34 adjacent unused sites, and 30 P. Nigromaculata spawning sites and 36 nearby unused sites. Our results showed that these two anuran species differed in the use of the main habitat types. B. gargarizans selected larger spawning sites with low levels of disturbance, high dissolved oxygen content, and the presence of fish. Conversely, P. nigromaculata preferred smaller waterbodies that were shallow, clear, and free of fish and B. gargarizans tadpoles. We conclude that differential habitat use and differences in response to abiotic conditions, predation risk, and competition, contributes to facilitating local coexistence and high species diversity in pond communities.

“…In amphibians, wetland complexes with a range of hydroperiods may facilitate temporal segregation to avoid interspecific competition or predation (cf. Vignoli et al, 2007; but see Indermaur et al, 2010). However, in the farmed area studied, amphibian assemblages were shown to exhibit a nested distribution among ponds; i.e., species-poor ponds harbored mainly the more common species (Kloskowski, 2010).…”

We classified the ponds into five types according to separate stocking of fish age-classes and culture-specific hydroperiod: early-flooded 0+ ponds (filled in March, exceptionally in the first two weeks of April), late-flooded 0+ ponds (filled between 1−15 May; ponds sampled for amphibians were filled prior to 7 May), all-year flooded 1+ ponds (ponds containing water continuously since the previous growing season when stocked with fry), re-filled 1+ ponds and 2+ ponds (both filled in March).…”

Key-words:aquaculture, anthropogenic wetland, ecosystem service, hydroperiod, pond biodiversityWe examined correlates of amphibian and waterbird diversity related to management practices, with a focus on timing of flooding, at shallow ponds used for common carp Cyprinus carpio culture in Eastern Poland. The age of the stocked fish was a strong predictor of amphibian diversity, with higher scores obtained in ponds with young-of-the-year carp compared to ponds containing older (and larger) fish. Pond cover by emergent vegetation was positively related to diversity of both taxonomic groups. The timing of filling affected the taxonomic richness of the ponds; in contrast to ponds filled in early spring (March-early April), early breeding amphibian species were not recorded in ponds filled later (early May). However, amphibian diversity did not differ between earlyand late-flooded ponds. Early availability of filled ponds favored waterbird species richness and diversity, and the hydroperiod effect overcame the effect of fish age/size. Dissimilar responses to hydroperiod onset may reflect differences between amphibian and bird communities in the nature and strength of interactions with fish. Timing of flooding, which appears to be a neglected determinant of biodiversity in anthropogenic wetlands, should consider the breeding and migration phenology of wildlife species and the presence and population structure of fish. RÉSUMÉLes pratiques de gestion pour améliorer la diversité de la faune des étangs piscicoles artificiels : l'importance de la hydropériode Mots-clés :aquaculture, zone humide d'origine anthropique, Nous avons étudié les liens entre la diversité des amphibiens et des oiseaux d'eau et les pratiques de gestion, avec un accent sur le calendrier des mises en eau, dans des étangs peu profonds utilisés pour la carpe commune Cyprinus carpio en Pologne orientale. L'âge des poissons déversés était un fort prédicteur de la diversité des amphibiens, avec des scores plus élevés obtenus dans les étangs avec des carpes jeunes de l'année par rapport aux étangs contenant des poissons plus âgés (et plus grands). La couverture de l'étang par la végétation émergente était Le calendrier des mises en eau, qui semble être un facteur déterminant négligé de la biodiversité dans les zones humides anthropiques, devrait prendre en compte la phénologie de la reproduction et de la migration des espèces de la faune, et la présence et la structure de la population de poissons.
