Species diversity and endemism in the Daphnia of Argentina: a genetic investigation
Analysis of mitochondrial DNA sequences and allozyme variation from 176 Daphnia populations from Argentina established the presence of at least 15 species in Argentina, six of which are either undescribed or are currently misidentified and two of which represent range extensions of North American taxa.
Comparative study of the planktonic communities of three lakes of contrasting trophic status at Hope Bay (Antarctic Peninsula)
This paper constitutes the first survey concerning all the planktonic compartments of water bodies of different trophic status at Hope Bay, describing the relative contributions of autotrophic and heterotrophic components to their food webs.
Cold-temperate lakes of South America : do they fit northern hemisphere models ?
It is suggested that cold-temperate lakes in Argentina differ in their thermal regime from northern hemisphere lakes at equivalent latitudes, owing to the marked oceanic influence on the southern hemisphere land mass, together with the strong and persistent westerly winds, which make the use of global models inadequate for Argentine cold- Temperate lakes.
New insights into the distribution of polyploid Daphnia: the Holarctic revisited and Argentina explored
The present study is the first to document the presence of polyploid members of the D. pulex complex in any temperate climate and provides important insights into the diverse factors that determine the distributions and evolutionary fates ofpolyploid organisms.
Induction and inhibition of spine development in the rotifer Keratella tropica.: Evidence from field observations and laboratory experiments
The results support the idea that a major proportion of the phenotypic expression of K. tropica depends on the concentration of an inducing factor, which in turn depends upon the balance between release and decomposition rates of the chemical, and suggest an inverse relationship between spine length and growth rate.
Review of the Eulimnadia (Branchiopoda: Spinicaudata: Limnadiidae) from Argentina with the description of a new species.
A new spinicaudatan species, Eulimnadia pampa sp. nov., is described from Argentina mostly based on the differential egg morphology. This species was collected from rainwater pools from Buenos Aires
UV Radiation as a Potential Driving Force for Zooplankton Community Structure in Patagonian Lakes
On the basis of the collected evidence it is not possible to definitely conclude that UVR rather than another covarying factor is responsible for the decrease in specific diversity observed at the lowest end of lake optical depth, but lakes with values above the previous threshold are likely to exhibit highly depauperate zooplankton communities regardless of the mechanism.
Effects of flooding and temperature on Aedes albifasciatus development time and larval density in two rain pools at Buenos Aires University City.
Significantly shorter development times were recorded for larvae of the first three stages as compared to the fourth larval stage and pupae of Ae.
The plankton communities from peat bog pools: structure, temporal variation and environmental factors
This is the first characterization of the structure and temporal variation of the plankton communities comprising the complete food web in five peat bog pools related to environmental factors over
