A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
Turkish Journal of Zoology
There has been a much debate about the relative importance of the determination of phytoplankton crops by nutrients (bottom-up control) or by zooplankton grazing (top-down control). Wide acceptance of the importance of nutrient concentrations in water quality deterioration has brought about external nutrient control by which eutrophication is, to some extent, reversible, and which has been proved its effectiveness mostly in deep lakes. In shallow lakes its effectiveness has not been as pronounced, owing to internal nutrient loading. Because the non-linearity of responses of biological systems is much more accentuated in small and shallow lakes. The use of profound effects …
Diurnal Variation Of Water Chemistry Andzooplankton In Little Mere, Cheshire, Uk, In 1993 And 1994, Meryem Bekli̇oğlu, Brian Moss
Diurnal Variation Of Water Chemistry Andzooplankton In Little Mere, Cheshire, Uk, In 1993 And 1994, Meryem Bekli̇oğlu, Brian Moss
Turkish Journal of Zoology
In Little Mere, diurnal sampling of the zooplankton at three different habitats in 1993 provided little evidence to support the data of Timms and Moss (10) that cladocerans move out from refugia at night to graze in open water. The floating-leaved water lily, appeared to be more efficient at providing refuge to D. hyalina in the presence of high planktivore fish predation than the submerged plant beds and the open water. This might be due to unfavourable physical and chemical environmental conditions associated with the water lily bed for fish feeding, a possibility supported by the findings of very low …

Some Morphological Features Of The Rectal Sac Of The Silkworm (Bombyx Mori: Bombycidae), Beri̇a Falakali Mutaf, Gamze Turgay
Turkish Journal of Zoology
The silkworm moth escapes from the pupal-protection case by utilizing cocoon-digesting enzymes. The rectal sac was examined in relation to the behaviour of the animal. Pupae and pharate adults were obtained from commercial races and were reared in the laboratory. The ball-shaped rectal sac, easily distinguishable within the abdomen of the silkworm, was found to contain two phased creamy fluid. The occurance and the shape of the organ and the usage of its fluid suggest its role in perforation of the cocoon.

A Note On The Examination Of Morphometric Differentiation Among Fish Populations: The Truss System, Cemal Turan
A Note On The Examination Of Morphometric Differentiation Among Fish Populations: The Truss System, Cemal Turan
Turkish Journal of Zoology
Identifying intraspecific units or stocks of a species with unique morphological characters enables a better management of these subunits of species and ensurs perpetuations of the resources. Multivariate morphometry has been commonly used to investigate the discreteness and interrelationships of stocks within a species. Different types of body measurements have been traditionally used to charecterise stocks. However these measurements have recently been criticised because there are several biases and weaknesses inherent in traditional characters. As an alternative, a new system of morphometric measurements called The Truss Network System has been increasingly used for stock identification. In this review a computer-originated …

The Use Of Coefficient Of Difference (Cd) In Systematic Zoology And The Subspecies Concept, C. Can Bi̇lgi̇n
The Use Of Coefficient Of Difference (Cd) In Systematic Zoology And The Subspecies Concept, C. Can Bi̇lgi̇n
Turkish Journal of Zoology
The use of the Coefficient of Difference (CD), which was first suggested some 50 years ago, as a measure of difference of a single character between two populations is not recommended today on grounds of statisticial weakness, its inability to evaluate more than one character simultaneously, and the often discordant variation of the characters studied. It is useful to utilize the statistically proven t-test or analysis of variance in cases when a few characters are studied, while multivariate distance measures such as Euclidian distance or discriminant function analysis will help determine differences between groups and taxon boundaries when many characters …
