rotifers of kepektas dam lake (elazig-turkey)*
with the aim of identifying the rotifera fauna of kepektas dam lake, samples were collectedmonthly between january-december 2005. in total 11 rotifer species were identified. as a species-wisepercentage, kellicttia longispina had the highest level with 57%. when the annual abundance of species wastaken into consideration polyarthra vulgaris, colurella uncinata, asplanchna priodonta and keratell...
متن کاملSpecies-specific separation of lake plankton reveals divergent food assimilation patterns in rotifers
1. The analysis of functional groups with a resolution to the individual species level is a basic requirement to better understand complex interactions in aquatic food webs. Species-specific stable isotope analyses are currently applied to analyse the trophic role of large zooplankton or fish species, but technical constraints complicate their application to smaller-sized plankton. 2. We invest...
متن کاملDiversity of sessile rotifers (Gnesiotrocha, Monogononta, Rotifera) in Thale Noi Lake, Thailand
In response to a clear gap in knowledge on the biodiversity of sessile Gnesiotrocha rotifers at both global as well as regional Southeast Asian scales, we performed a study of free-living colonial and epiphytic rotifers attached to fifteen aquatic plant species in Thale Noi Lake, the first Ramsar site in Thailand. We identified 44 different taxa of sessile rotifers, including thirty-nine fixose...
متن کاملPlanktonic Rotifers in a Subtropical Shallow Lake: Succession, Relationship to Environmental Factors, and Use as Bioindicators
Changes in the density and species composition of planktonic rotifers as well as their relationship to several environmental variables were studied at Dadian Lake, a shallow subtropical lake, which was completely dredged and reconstructed. Samples were taken monthly (2006-2009) at five stations. The total rotifer abundance exponentially declined and reached a relatively stable stage in 2009. Po...
متن کاملBdelloid rotifers revisited.
S exual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization. But many eukaryotes reproduce asexually part of the time, and some are exclusively asexual (1, 2). Two articles in a rece...
