“…Although there is some information about Microcarbo pygmaeus, Nycticorax nycticorax, Ardeola ralloides, Bubulcus ibis, Egretta garzetta species inhabiting the coastal strip from the southwestern coast of the Caspian Sea (401204N-502214E) to the border with the Islamic Republic of Iran [1], the effect of the decrease in the water level and the destruction of reeds and tamarisks on their reproductive behavior has not been studied. In general, the adaptation of waterfowl, shorebird and other ecological groups of birds to changes in water level has been poorly studied [7,12].…”

“…In ornithological local literature, the latest information about the nature of settlement, reproduction, trophic and biotopic relationships of waterfowl and shorebird migratory-nesting bird populations in the Azerbaijani sector of the South-Western coast of the Caspian Sea were provided by different scientists [8,13,14,15]. Although studies on the nesting and breeding behaviour of these species (M.pygmaeus, N. nycticorax, A.ralloides, B.ibis, E.garzetta) have been conducted in several European countries [1,2,5,6,11], as well as in Asia, such researches are new in Azerbaijan.…”

N 2008-2023, the changes in breeding behavior of the migratory-nesting bird populations of Microcarbo pygmaeus, Nycticorax nycticorax, Ardeola ralloides, Bubulcus ibis, Egretta garzetta on biotopes were studied on the South-Western coast of the Caspian Sea. Hundreds of thousands of bird populations from Africa and South-East Asian countries migrate to the Azerbaijani sector of the South-Western part of the Caspian Sea every year. Among the above-mentioned bird species only Bubulcus ibis has a migratory-nesting population in the Gizilaghaj Bay of the Caspian Sea. The rest of the species have migratory-nesting and sedentary populations. The number of migratorynesting populations in the study area is a hundred times more than that of sedentary populations. During this period, intra-species and inter-species competition intensifies in the struggle for nesting, feeding, roosting, resting, shelter and other living conditions between migratory-nesting and sedentary bird populations. The water level reduction and the related destruction of reeds and tamarisks, intraspecies and inter-species competition lead to changes in the breeding behaviour of migratory-breeding bird populations. As a result, the continuous, sustainable reproduction of these species becomes difficult, and the adoption of new nesting places by the species makes conservation problems more urgent.

Introduction: Cryphiops caementarius, is an endemic prawn from river ecosystems in Southern Perú and Northern Chile. In these watersheds, natural populations are threatened by multiple anthropic interventions such as mining activities and fishing pressure, but also, by increasing impacts of invasive exotic predators. Information related with predation on C. caementarius is scarce representing a major knowledge gap to ensure suitable management and conservation practices. Accordingly, the further deepening in relevant aspects such as the estimation of populations losses due to predators has been indicated as critical by relevant agencies as FAO. Objective: To conduct a complete registry and classification of C. caementarius predators, updating the knowledge for the Andean region. Methods: A thorough bibliographic review on existing information on C. caementarius' predators from Perú and Chile was carried out calculating percentage of occurrence, relative frequency of species, zoogeographic origin, trophic structure, phenotypic attributes, river zone that inhabits and life stage of incidence. The registry was complemented using semi-structured interviews from prawn´s fishers in central-Northern Chile. Results: C. caementarius is predated along the entire fluvial network (estuary, potamon and rhithron) by 21 species of opportunists, carnivores, omnivores and herbivores, mostly aquatic vertebrates. In turn, these belong to 15 families and six guilds of native, exotic and cosmopolitan species. Approximately 86 % predate on adult prawns, whilst, 71 % on juveniles and 24 % on larvae. More than 40 % of the predation pressure seems to be exerted by native waterfowls and 24 % by exotic fish. Conclusions: The results emphasize the relevance for conservation of native species of predators in the Andean region and the need of control measures on exotic species in a latitudinal basis. Accordingly, this review may serve as an initial decision-making tool for future conservation efforts both on prawns and native biota, but also supporting restocking actions, fisheries management plans and risk assessment for C. caementariuspopulations across the Andean region.
