Life History Features Of The Nonindigenous Three-Spined Stickleback (Gasterosteus Aculeatus Linnaeus, 1758) In The Gomishan Wetland (Southeast Caspian Sea, Iran), Rahman Patimar, Mariam Horry Najafabadi, Manizheh Ghadi Souraki

Turkish Journal of Zoology

The Caspian Sea forms the southern limit of the distribution range of the three-spined stickleback (Gasterosteus aculeatus), but little is known about its life history in this area. A total of 362 specimens were collected from the Gomishan wetland (southeast Caspian Sea, Iran) to describe the stickleback's life history characteristics. Samples were taken monthly between February and July of 2008. The maximum ages of the population observed were 2+ years for males and 3+ years for females. The length-weight relationship (LWR) was estimated as W = 0.0042TL^{3.711} for immature specimens, W = 0.0095TL^{3.1328} for males, and W = 0.0057TL^{3.4678} for …

Gonad Histology Of The Persian Tooth-Carp Aphanius Persicus (Jenkins, 1910) (Cyprinodontidae) In Southern Iran, Malihezaman Monsefi, Amir Houshang Shiva, Hamid Reza Esmaeili

Turkish Journal of Zoology

The histological changes of gonads were studied in Aphanius persicus from the Barm-e-Shoor spring (south of Iran). The gonads were extracted and prepared histologically. The maturity stage of each specimen was examined according to size and weight of gonad, degree of occupation in the body cavity, the type and number of germinal cells (in testis) and follicles (in ovary). We have described 5 sexual stages for females and 4 for males. The total length and body and gonad weight of each specimen increased with increasing maturity stages. In females, the appearance of ripe oocytes was in stage IV and V …


Multivariate Morphometric Study On Apis Florea Distributed In Iran, Ayça Özkan, Mohammed M. Gharleko, Berna Özden, İrfan Kandemi̇r Jan 2009

Multivariate Morphometric Study On Apis Florea Distributed In Iran, Ayça Özkan, Mohammed M. Gharleko, Berna Özden, İrfan Kandemi̇r

Turkish Journal of Zoology

Multivariate Morphometric and Spatial Autocorrelation Analyses were performed to determine the morphometric variation in Apis florea colonies representing 13 localities from 4 states on the coastal north-south diagonal in Iran. New morphometric characters (hind wing length, hind wing width, and hind wing angles) were also measured to determine the usefulness of these characters for Apis florea. Analysis of variance of new morphometric characters showed that 7 out of the 8 hind wing variables displayed statistically significant differences among populations (P < 0.05). The scatter plot from Canonical Variate Analysis revealed that the colonies from north (Ilam, Khuzestan, and Bushehr states) showed an overlapping distribution. The colonies from south (Hormuzgan state) formed a non-overlapping distant cluster. Based on the spatial autocorrelation analysis, 14 correlograms were significant for morphometric characters (According to the Bonferroni criterion). Six characters (CuB, C.Ind, HWW, B4, D7, and I13) showed clinal type correlogram.

Turkish Journal of Zoology

The karyotypes of 2 bat species from Iran were examined. The diploid number of chromosomes (2n) and the fundamental numbers of chromosomal arms (NFa) were determined to be 2n = 44 and NFa = 54 for Myotis blythii and 2n = 46 and NFa = 50 for Miniopterus schreibersii, respectively. The karyotypes of Iranian bats show similarity within populations in other countries with respect to the diploid chromosome numbers; however, they are quite different in the fundamental chromosome numbers and the numbers of autosomal arms.


Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek Jan 2008

Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek

Turkish Journal of Zoology

Three water shrew specimens were collected in the Sheshpir spring (2303 m a.s.l.), Fars province, south-western Iran. In pennial morphology, which is species-specific in the genus Neomys Kaup, 1829, the specimens were indistinguishable from N. anomalus Cabrera, 1907. The Sheshpir spring is located approximately 900 km to the south-south-west of Gorgan, the only site in Iran where N. anomalus has been known to occur so far. The spring is a stony basin with bare banks and poorly developed aquatic vegetation and as such is an atypical habitat for water shrews. It is noteworthy that fish are absent in the spring.

Efficacy Of The Rodenticide Bromethalin In The Control Of Microtus Arvalis And Nesokia Indica In Alfalfa Fields, Alireza Khalilaria, Mohsen Morovati, Mehdi Naseri Jan 2007

Efficacy Of The Rodenticide Bromethalin In The Control Of Microtus Arvalis And Nesokia Indica In Alfalfa Fields, Alireza Khalilaria, Mohsen Morovati, Mehdi Naseri

Turkish Journal of Zoology

Rodents cause huge losses to agricultural crops annually. During outbreaks, this pest can cause irreversibly high damage. Solely non-chemical control measures have not been successful in reducing the population of this pest; therefore, the use of chemical rodenticides, especially on crops like alfalfa, is unavoidable. Bromethalin is a neurotoxic, acute, single-dose rodenticide with high efficacy, and since it is mostly used in wax formulation it is not attractive to non-target organisms, and hence is not very dangerous. Bromethalin 0.01% was tested in alfalfa fields of west Azerbaijan, Tehran, and Kerman provinces in completely randomised treatment blocks with 4 treatments (bromethalin …


Biometrical Study Of Artemia Urmiana (Anostraca: Artemiidae) Cysts Harvested From Lake Urmia (West Azerbaijan, Iran), Alireza Asem, Nasrullah Rastegar-Pouyani, Naser Agh Jan 2007

Biometrical Study Of Artemia Urmiana (Anostraca: Artemiidae) Cysts Harvested From Lake Urmia (West Azerbaijan, Iran), Alireza Asem, Nasrullah Rastegar-Pouyani, Naser Agh

Turkish Journal of Zoology

Artemia urmiana was reported from Lake Urmia by Günther in 1899. The objectives of the present study were to investigate the diameter of untreated and decapsulated cysts and chorion thickness at 26 stations in Lake Urmia. One-way ANOVA (Tukey test, P < 0.05) was used for analyzing the data. Only 31 pair means of untreated cysts among 26 stations showed significant differences, but, on the other hand, 157 pair means of decapsulated cysts among stations showed significant differences. There was a high variation in cyst diameter among the different localities in Lake Urmia. It was shown that this lake consists of recognizable sections producing cysts with different hatching characteristics, which can be used for diverse aquacultural purposes.
