Species assemblages of zooplanktonic crustaceans in mountain shallow ponds of Chile (Parque Cañi)
Zoologia (Curitiba), 2010 Even though the Chilean lakes are characterized by their oligotrophy, a transition from oligotrophy to mesotrophy, due human intervention, has been reported in some lakes.

New species of Boeckella (Copepoda: Calanoida)
Papers and proceedings of the Royal Society of Tasmania, 1967 The new species, Boeckella bispinosa, is described and figured from Tasmanian material. The male fifth legs of B. opaqua Fairbridge, a Western Australian species, are figured and the original description supplemented. The female genital segment of B. pseudocheZae Searle is figured. New records of B. symmetrica Sars, B. minuta Sars, and B.

Iheringia: Série Zoologia, 2012 Calanoid copepods are abundant in South American inland waters and include widespread species, such as Boeckella gracilipes (Daday, 1902), which occurs from the Ecuador to Tierra del Fuego Island. This species occurs under various environmental conditions, and is found in oligotrophic lakes in Patagonia (39-54°S) and in shallow mountain lakes north of ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.Ephemeral salt lakes in arid Australia contain hidden macroinvertebrate biodiversity in sediment egg banks, but traditional artificial rehydration surveys may miss taxa with specific or poorly understood hatching requirements. This study found that sugar‐flotation followed by DNA metabarcoding greatly improved detection of resting‐stage taxa compared ...

Limnology and Oceanography, Volume 70, Issue S2, Page S315-S331, December 2025.Abstract Regulation and water extraction change flow regimes in lowland rivers, affecting ecosystem functions and wetting patterns of riverbanks. River connectivity to lateral environments is crucial for organic matter cycling and the life cycles of diapausing microinvertebrates. While extreme hydraulic periods (floods and cease‐flow) are well‐studied,

Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT We carried out short‐term field experiments (duration 1–3 days) to study the impact of predation by natural densities of Boeckella major on zooplankton in Australian ephemeral billabongs (oxbow lakes). Predation reduced total zooplankton densities by 33.6%–91.9%.

Potential heterogeneity in crustacean zooplankton assemblages in southern chilean saline lakes
Brazilian Journal of BiologyThe Chilean saline lakes are distributed mainly in the Atacama desert in northern Chile and the southern Patagonian plains. The scarce studies are restricted mainly to northern Chilean saline lakes, and these revealed that the main component in these ...
