“…Hydroperiod onset issues are not trivial in human-managed wetlands, because timing of flooding is highly dependent on the type of wetland use (e.g. Azous et al, 2000;Jurajda et al, 2004;Koji et al, 2014). We believe that protection of the breeding habitat of pond wildlife has not sufficiently taken into account the phenology of immigration in amphibians and of spring arrival in birds (cf.…”

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.
