Abstract
Changes among chydorid assemblages in Lake La Cruzsediments, from a core of 178 cm length, have beenstudied using community structure indices andmultivariate methods (cluster analysis, principalcomponents analysis).The results revealed the existence of two main sourcesof variation in these assemblages. One (axis I ofPCA1) is associated with the trophic level of thelake, which is hypothetised to be greater in thebottom and upper part of the core. Both zones arecharacterised by an increase in the relative frequencyof Chydorus sphaericus, accompanied by a markedreduction in the relative frequency of the mostabundant species throughout the history of the lake,Acroperus neglectus.The other source of variation (axis II of PCA1) may beinterpreted as the alternation of periods of dryer and wetter weather. Ouranalyses show the separation of two assemblages whichalternatively prevail in the sedimentary sequence, oneconstituted by Pleuroxus laevis, Alona guttata,Graptoleberis testudinaria and, sometimes, Alonarectangula, and another dominated by Chydorussphaericus, Alona quadrangularis, Alona affinis andsometimes Leydigia species. According to theecological preferences of these species, the dominanceof the first chydorid assemblage can be related toepisodes of higher temperature and with very low andfluctuating water level, or with a high water levelbut a very reduced extent of shallow water in thelake. Prevalence of the second group corresponds toepisodes with a colder environment and permanentwaters, the level of which could be variable but insuch a way that a benthic sublittoral zone maydevelop. The structure of the community is stronglyaffected by changes in lake level. High indices offluctuation in community structure and small mean bodysize of the chydorid assemblage marked the period withmore extreme dry conditions, characterised by Alona rectangula maxima. The peaks of C. sphaericuscoincided with peaks of the index offluctuation D0 and prevalence of smaller speciesof the chydorid assemblage.
