“…The biological assemblage in Laguna Blanca Grande is typical of shallow, eutrophic and alkaline freshwater systems from the Pampean region (Hassan, 2011;Laprida, 2006;Paggi, 1998b;Plastani et al, 2019;Smol, 1985). Biological proxies coupled with sediment properties' changes suggested a shift in nutrients and hydroclimatic conditions during the last centuries.…”

“…In addition to the intrannual variability, the region is strongly influenced by interannual phenomena such as the El Niño Southern Oscillation (ENSO). As a result of these different modes of climatic variability, the Pampean lakes have shown important lakes level changes during the Holocene, as demonstrated in Laguna Mar Chiquita (Cuña-Rodriguez, 2018;Coianiz et al, 2014;2004;2002), Lagunas Encadenadas del Oeste de Buenos Aires (Córdoba, 2012;, Lake Nahuel Rucá (Stutz et al, 2010), Lake Lonkoy (Stutz et al, 2012), Lake La Barrancosa (Plastani et al, 2019), Lake Adela (Dangavs and Mormeneo, 2012), Laguna del Monte (Dangavs and Pierrard, 2013), Lake La Brava (Irurzun et al, 2014; and Lake Melincué (Guerra et al, 2015;) (Fig. 1).…”

“…1930, based on eolic records, but could be considered to have an effect on the eastern Pampa plain. Plastani et al (2019) suggested that La Barrancosa lake (southeastern Pampa plain) was among the lakes that underwent desiccation caused by the droughts of the 1930s. For Chasicó lake, southwestern Pampa plain, a very dry period and extremely low lake levels between 1930 and 1970 AD were inferred (Frazer et al 2020).…”

Pampa Plain (Argentina) Wetland History through a Lake Case Study: Kakel Huincul Environmental History during the Last 600 Years

et al. 2023

Wetlands are considered key ecosystems because of the greatest number of ecosystem services they provide, but despite their important role these ecosystems are decreasing in size and losing quality. Kakel Huincul lake is located in one of the main wetlands of Argentina. A multi-indicator analysis, including pollen, non-pollen palynomorphs and plant macrofossil remains was performed to reconstruct Kakel Huincul lake environmental history in order to understand Pampean wetlands responses to environmental changes and human impacts during the last 600 years. Results showed that changes in the lake communities before 1880 AD were a result of climatic perturbations (increase/decrease rainfall), and after 1880 AD they were a combination of climatic (increases and decreases of precipitation values) and anthropic forcings (cattle, intensive agriculture and urbanization). Baseline conditions were established at ca. 1870 AD and it was concluded that southeastern Pampa plain has been subjected to human activities (cattle farming and incorporation of agriculture) since then. Eutrophication of the lake occurred during the last 25 years, but this study made it possible to establish that the Pampa wetland has been modi ed for more than ve decades ago.

“…Pampean lakes also provide evidence on eutrophication increases due to human activities. In particular, Plastani et al (2019) analyzed the main forcing factors behind hydrological shifts during the past ca. 200 years in the lake La Barrancosa, located in the southern humid Pampa, between the low mountain systems of Tandilia and Ventania.…”
