Preliminary Phylogeny Of The Thrips Parasitoids Of Turkey Based On Some Morphological Scales And 28s D2 Rdna, With Description Of A New Species, Oguzhan Doğanlar, Mi̇kdat Doğanlar, Anne Frary
Turkish Journal of Zoology
Species of the Ceranisus thrips-attacking genus are difficult to distinguish morphologically. The phylogenetic relationships within the Ceranisus species were explored using nucleotide sequences of the 28S D2 expansion region of the rDNA gene. Bayesian, maximum likelihood, and parsimony inference methods were employed to construct the phylogenetic relationships. Principal component analysis on the Turkish species of Ceranisus, namely antalyacus, menes, bozovaensis, hirsutus, planitianus (a new record for Turkey), pacuvius, and a new species, provided supporting evidence. All known data concerning hosts and geographical distribution are presented. A new species, C. onuri O. Doganlar, sp.n., was described from Turkey.

The Effect Of Caloric Restriction On The Population Density Of Freshwater Rotifers (Brachionus Calyciflorus), Ni̇lgün Özdemi̇r, Abdulkadi̇r Çi̇ltaş
Turkish Journal of Zoology
The effects of caloric restriction (CR) on the population density of freshwater rotifers (Brachionus calyciflorus) were investigated in the present study. During experiments with different CRs, groups of rotifers were fed with Chlorella sp. at the same concentrations of 1.5 × 10^6 cells/mL at 12, 24, 36, 48, 60, and 72 h intervals for 20 days. Significant changes were observed both in the population density and the peak days in groups subjected to different CRs (P < 0.01). The highest peak in population density was obtained on the fifth day for rotifers fed in 12 h intervals (269 ± 40.12 individuals/mL, mean ± SD). The rate of population increase (r) varied from 0.608 ± 0.073 to 0.288 ± 0.053, depending on the feeding intervals. The results show that CR affected the population density of B. calyciflorus.
