“…That is highly coincident with the results found by Bucher and Herrera (1981) in a similar study carried out in the Mar Chiquita Lake, one of the biggest salt lake in the world (Reati et al 1997). The species composition was also similar between both studies (Sørensen resemblance index=0.844).…”

“…This is coincident with the results from Ce´zilly et al (1995) in the Camargue (France), Garcı´a et al (1997) in Fuente de Piedra Lake (Spain), and with the results from Lo´pez de Casenave and Filipello (1995) for the Reserva Costanera Sur (Argentina). In contrast, Scott and Carbonell (1986 cited by Reati et al 1997) showed a reduction in bird abundance when shore environments disappeared due to an increase in water level. Similar observations were done by Johnsgard (1956) for a group of wetlands in the state of Washington (USA) and by Bucher (1992) in Mar Chiquita Lake (Argentina), where an increase in water level caused that the shoreline be in contact with the shrubby vegetation, and therefore suitable environments for waterbirds disappeared.…”

“…The dynamic of these systems is controlled by fluctuations at a temporal scale that ranges from several years to decades (Reati et al 1997). Short-term studies that do not take into account the particular dynamic of these systems may lead to erroneous generalisations, with a corresponding impact on their management and conservation (Bucher 1992;Garcı´a et al 1997;Menegheti and Dotto 2002).…”

“…However, the magnitude of these seasonal variations is small when compared with cyclical pluriannual variations that result from wet or dry macroclimatic cycles (ENSO) (Bucher 1992;Reati et al 1997;Piovano et al Fig. 1 Location of the three survey transects (North, East and West transects) in the Melincue´saline lake (Argentina).…”

“…That in turn conditions the bird abundance by affecting the presence, abundance, and/or diversity of food resources (e.g. fishes, submerged macrophytes, invertebrates, algae, etc) (Garcı´a et al 1997;Reati et al 1997;Bucher et al 2000). In Melincue´, in high water-level years, the relative increase of those species that fed on plants, vertebrates and invertebrates, except shorebirds, may be related to the change in the chemical composition of water (salinity reduction) and to the increase of shallow water areas and flooded grasslands, which in turn favours an increase in the population of the plants and prey species (e.g.…”

We conducted 14 bird surveys in the Melincueś aline lake from 1992 to 2002 (7 in winter and 7 in summer), and we detected 223,643 individuals belonging to 71 species from 17 families. The more abundant species were Fulica leucoptera, Larus maculipennis, Phoenicopterus chilensis, Plegadis chihi, Anas platalea, Himantopus mexicanus, and Rollandia rolland. Bird abundance was similar in winter and summer, whereas species composition differed between seasons. We recorded 65 species in summer and 59 in winter. P. chilensis and A. sibilatrix were more abundant in winter, whereas Ajaia ajaja, Phalacrocorax olivaceus, Ardea ibis, Sterna nilotica, Egretta thula, Mycteria americana, Charadrius collaris, A. versicolor, Calidris fuscicollis, and Ciconia maguari were more abundant in summer. Bird abundance in each survey was positively associated with the lake level. In summer surveys, the highest variation in species composition through the years was associated with water level fluctuations. Shorebirds predominated in those years with lower level, whereas the species that fed mainly on plants or vertebrates predominated in years with higher levels. Those species that fed on invertebrates (not shorebirds) and those that fed on invertebrates and plants predominated in years with intermediate level. The omnivorous species predominated in years of lower level. There were differences among transects in the proportion of different trophic groups. Short-term studies that do not take into account the particular dynamic of these systems may lead to erroneous generalisations. Thus, the long-term information of this study may be useful for management and conservation of species and system.
