Донные диатомовые водоросли соленых озер Крыма IBSS Repository
Неврова, Е. Л.; Шадрин, Н. В..
В результате комплексных исследований соленых и гиперсоленых озер морского происхождения Крыма обнаружено, что фотоавтотрофы представлены в основном одноклеточными микроводорослями (Bacillariophyta, Cyanophyta) и нитчатыми зелеными водорослями (род Cladophora), образующими плавучие поля-маты размером в сотни квадратных метров. Биомасса Cladophora при глубине 35 -45 см в оз. Байкальском достигает 8 - 10 кг·м‾², биомасса микроэпифитона, состоящего почти целиком из диатомовых и цианобактерий. Колеблется от 50 до 800 г·м‾². Всего в исследованных озерах отмечено 73 вида (74 внутривидовых таксона) донных диатомовых водорослей (Bacillariophyta). Наиболее широко представлен класс Bacillariophyceae - 21 род, 64 вида, принадлежащих к 9 порядкам, 16 семействам....

Biogeochemical processes and the diversity of Nhecolândia lakes, Brazil Anais da ABC (AABC)
Almeida,Teodoro I. R; Calijuri,Maria do Carmo; Falco,Patrícia B; Casali,Simone P; Kupriyanova,Elena; Paranhos Filho,Antonio C; Sigolo,Joel B; Bertolo,Reginaldo A.
The Pantanal of Nhecolândia, the world's largest and most diversified field of tropical lakes, comprises approximately 10,000 lakes, which cover an area of 24,000 km² and vary greatly in salinity, pH, alkalinity, colour, physiography and biological activity. The hyposaline lakes have variable pHs, low alkalinity, macrophytes and low phytoplankton densities. The saline lakes have pHs above 9 or 10, high alkalinity, a high density of phytoplankton and sand beaches. The cause of the diversity of these lakes has been an open question, which we have addressed in our research. Here we propose a hybrid process, both geochemical and biological, as the main cause, including (1) a climate with an important water deficit and poverty in Ca2+ in both superficial and...

Biology of Boeckella poopoensis Marsh, 1906 (Copepoda, Calanoida) in natural conditions in temporary saline lakes of the central Argentina Biota Neotropica
Vignatti,Alicia María; Cabrera,Gabriela Cecilia; Echaniz,Santiago Andrés.
Boeckella poopoensis Marsh, 1906 is the dominant copepod in saline lakes from northern Patagonia to southern Peru. It is a tolerant species, which has been registered at salinities between 20 and 90 g.L-1, and is important because it integrates the diet of flamingos and fishes of commercial and sport interest. The aims of this study were to analyze the characteristics of populations of B. poopoensis in the central region of Argentina and to establish their relationships with environmental parameters. Monthly samples during 2007 were taken in four temporary lakes of La Pampa province. Environmental parameters and density, size, biomass, number and size of eggs were determined. The salinity ranged between 13.38 and 32.90 g.L-1. In three lakes that had...
