Pelagic communities and ecosystem processes in Andean Patagonian lakes

Ecología Austral, 1998
Limiting nutrients, nitrogen and phosphorus, are of crucial importance in the structure and dynamics of freshwater plankton. Oligotrophic lakes are nutrient limited environments and therefore their plankton dynamics depends mostly on internal mechanisms

Diversity of Freshwater Calanoid Copepods (Crustacea: Copepoda: Calanoida) in North-Eastern China

Diversity
The distribution and diversity of calanoid copepods were investigated using samples collected from 37 lakes in North-eastern (NE) China in 2019. A total of 10 calanoid copepods belonging to eight genera and three families were identified.

Comparación de los parámetros limnológicos y el zooplancton de un lago somero salino de La Pampa (Argentina) durante dos ciclos anuales con condiciones ambientales diferentes

Biología Acuática, 2019
In central Argentina the alternation of cycles of rainfall above or below the historic mean is frequent; so, many saline lakes can dry or fill in a short time.

Características limnológicas de una laguna turbia orgánica de la provincia de La Pampa y variación estacional del zooplancton

Biología Acuática, 2019
In La Pampa province, shallow lakes (water bodies of low depth, generally polimictic and with high trophic level) are abundant and broadly distributed. Although previous contributions on these shallow lakes are about their ecology and zooplankton, only ...

Corta meromixis en un lago somero de la región semiárida pampeana

Biología Acuática
Los lagos meromícticos son aquellos que no se mezclan en su totalidad debido a un fuerte gradiente salino que separa el mixolimnion (superficial, menos salino) del monimolimnion (profundo, más salino). La laguna Este de la Reserva Provincial Parque Luro

Feeding of Boeckella gracilipes (Copepoda, Calanoida) on ciliates and phytoflagellates in an ultraoligotrophic Andean lake [PDF]

Journal of Plankton Research, 2001
The calanoid copepod, Boeckella gracilipes, is the dominant crustacean zooplankton in South Andean deep ultra-oligotrophic lakes. Combining field and experimental data we explored the feeding of the copepod and its access to the mixotrophic ciliate, Ophrydium naumanni, in Lake Moreno Oeste (Patagonia, Argentina).

Primeras observaciones en características reproductivas en poblaciones chilenas de Copépodos Calanoideos de aguas continentales First observations on reproductive characteristics on Chilean Patagonian populations inland water Calanoids Copepods

Gayana, 2012
Los copépodos calanoideos son abundantes en los ensambles zooplanctónicos de aguas continentales de la Patagonia, y en este contexto, se analizaron parámetros de fertilidad en cuatro especies de calanoideos representativos de aguas continentales de la ...

Zooplankton Assemblages of an Argentinean Saline Lake during Three Contrasting Hydroperiods and a Comparison with Hatching Experiments

Limnological Review
Many saline lakes are temporary, with large variations in salinity, and their biota is adapted to withstand unfavorable periods. Utracan Lake, in a protected area in central Argentina, was studied on three occasions under different environmental ...
