Observations On The Reproduction And Feeding Biology Of Lacerta Laevis (Sauria: Lacertidae) Gray, 1838, Kurtuluş Olgun
Observations On The Reproduction And Feeding Biology Of Lacerta Laevis (Sauria: Lacertidae) Gray, 1838, Kurtuluş Olgun
Turkish Journal of Zoology
In this study, the feeding behaviours of the new hatched eggs which were laid to the terrarium by one of the 18 Lacerta laevis samples collected from Mersin (Fındıkpınarı) were observed and the development of these eggs over 103 days period were investigated. In conclusion the number of the eggs laid by one of the lizards were six, the mean size of eggs were 8.03 x 12.25 mm. and the mean body length of the young, that were hatched after 47 days, was 77.77 mm. at the first day and was 89.14 mm. at the end of 56 th day.
A Study On The Flesh Productivity And Standard Method For Collecting Of Helix Lucorum Linnaeus, 1758, M. Zeki̇ Yildirim, M. Rüştü Özen, Mustafa Ünlüsayin, Hayri̇ Gülyavuz
A Study On The Flesh Productivity And Standard Method For Collecting Of Helix Lucorum Linnaeus, 1758, M. Zeki̇ Yildirim, M. Rüştü Özen, Mustafa Ünlüsayin, Hayri̇ Gülyavuz
Turkish Journal of Zoology
In this study that has been verified at the Eğirdir environs, Helix lucorum which is one of the edible terrestrial snail species in Turkey, and a standard method of collecting snail samples for consumption were investigated. In the area of study, it was observed that individuals begin to reproduce at the second week of February and that they are spawninig during March-May when the climate is mild. It was also determined that the minimum shell length of individuals is 22 mm, and that shell diameter is 31 mm, and that weight is 10 g which were measured during reproducing period. …
Ecology And Biology Of Allactaga Elater, Allactaga Euphratica Andallactaga Williamsi (Rodentia: Dipodidae) In Turkey, Ercüment Çolak, Nuri Yi̇ği̇t
Ecology And Biology Of Allactaga Elater, Allactaga Euphratica Andallactaga Williamsi (Rodentia: Dipodidae) In Turkey, Ercüment Çolak, Nuri Yi̇ği̇t
Turkish Journal of Zoology
The young of Allactaga williamsi and Allactaga euphratica were born at an average weigth of 2.51 and 2.74 g., respectively. Litter size ranged from 3 to 6 with an average of 4.8 in A. williamsi, and it changed from 4 to 8 with an average of 4.8 in A. euphratica , A. williamsi breeds during the period of March to August, A. williamsi and A. euphratica produced 2 and 2 or 3 litters per year, respectively. Allactaga elater has four types of burrows: winter, summer, reproduction and temporary. A. williamsi and A. euphratica have two types of burrows: reproduction and …
An Investigation On The Reproduction Properties Of Chub ( Leuciscus Cephalusl., 1758) In Lake Tödürge (Zara/Sivas)*, Bülent Ünver
An Investigation On The Reproduction Properties Of Chub ( Leuciscus Cephalusl., 1758) In Lake Tödürge (Zara/Sivas)*, Bülent Ünver
Turkish Journal of Zoology
In this study, the reproductive properties of the chub population ( Leuciscus cephalusL., 1758) in lake Tödürge, Zara/Sivas, were investigated. A total of 674 specimens were caught between April and November 1994. The age and sex distributions and the age of sexual maturity were determined. The reproduction period of the population was determined. Fecundity was determined and the relationships between the fecundity and body weight, length and age were investigated. The age composition of specimens of the population consisting of 68.25% female and 31.75% male, was found to be between I and VII. Males reached maturity in their second or …
The Annual Reproductive Cycle Of Oryzomys Palustris In A Virginia Tidal Marsh, Erin A. Dreelin
The Annual Reproductive Cycle Of Oryzomys Palustris In A Virginia Tidal Marsh, Erin A. Dreelin
Biological Sciences Theses & Dissertations
The objectives of my study were to determine when the marsh rice rat (Oryzomys palustris) begins and ends reproduction during the year, if there are seasonal changes in litter size, and the weight at which sexual maturity is reached. Monthly samples of rice rats were trapped from May 1995 to May 1996 in Northampton County, Virginia. Rice rats were trapped with Fitch live traps, euthanized in the field, and brought to the lab for necropsy. Data from two other studies of rice rats in Northampton County were also examined. Potential breeders did not reproduce with equal intensity throughout the …

TERRAPENE CAROLINA CAROLINA (Eastern Box Turtle). REPRODUCTION. Female Terrapene carolina containing oviductal eggs have been recorded in Virginia from 26 May to 25 July (Mitchell, in press. The Reptiles of Virginia. Smithsonian Inst. Press, Washington, D.C.). Other reports of reproduction in Terrapene (see list in Ernst and McBreen 1991. Cat. Amer. Amphib. Rept. 512.1-512.13) indicate that nesting occurs in late spring and early summer throughout its range.
Evaluation Of The Gross Anatomy Seasonal Changes Function And Histology Of The Perineal Gland In The Hispid Cotton Rat, Sigmodon Hispidus, Julie Anne Winchell
Evaluation Of The Gross Anatomy Seasonal Changes Function And Histology Of The Perineal Gland In The Hispid Cotton Rat, Sigmodon Hispidus, Julie Anne Winchell
Biological Sciences Theses & Dissertations
The perinea! gland in the hispid cotton rat, Sigmodon hispidus, is a seasonally cyclic, subcutaneously located organ which is associated with the reproductive system. On gross dissection, the gland possesses a strong attachment to the penis with only loose fascia! connections to the rectum and surrounding muscle and skin. Histologic exam confirms this connection to the reproductive tract and shows the organ to be a compound tubuloacinar gland with a projection leading into the penis. The cyclic hypertrophy and regression of the gland closely parallels that of the testes and seminal vesicles indicating that this cyclicity may be under …
An Analysis Of External Features As Predictors Of Reproductive Status In Small Mammals, Kenneth Wayne Mccravy
An Analysis Of External Features As Predictors Of Reproductive Status In Small Mammals, Kenneth Wayne Mccravy
Biological Sciences Theses & Dissertations
Reproductive status in specimens of nine populations of seven species of small mammals was evaluated by examining the external reproductive features of nipple size, condition of the pubic symphysis, and vaginal condition and, in males, testis position. Usefulness of these external features in predicting true monthly breeding rates was evaluated by comparing predictions of breeding rates with true rates based on necropsy. Accuracy of predictions of reproductive status of individuals based on single external features and combinations of external features and body measurements was then analyzed at a finer level by comparing those predictions with results of necropsy of the …
