چکیده
In this study, histological and macroanatomical structures of porcupine penis were examined on 3 adult male porcupines. The non-erectile position of porcupine penis was directed to caudal. There was an obvious collum penis. Glans penis with a black colour was easily distinguished from corpus penis which had a white color. There were cornified papillae covering on both the glans penis and corpus penis. Two small nail symmetrical structures were noted in connective tissue just behind of glans penis, and under the urethra of the corpus penis were distinguished. Histological examinations indicated that these structures histologically fulfilled completely to the name as the nail contained an inner and an outer layer, namely, connective tissue and keratin, respectively. Histological evaluations also showed that it is suitable to categorize the porcupines penis as vascular type. In conclusion, the anatomy of porcupine penis was initially examined in the present study. Our findings will make an important contribution to the knowledge of similar subjects.

The Crested porcupine (Hystrix cristata L.) has been shown to have considerably increased in numbers, and to have occupied new territories in Tuscany, which is the northernmost part of its range. New data on its ecology and biology, and the negative effects of an excessive density of these rodents on the rural and natural environment are reported. Since this species is protected by law in Italy...

Studying the evolutionary dynamics of an alien species surviving and continuing to expand after several generations can provide fundamental information on the relevant features of clearly successful invasions. Here, we tackle this task by investigating the dynamics of the genetic diversity in invasive crested porcupine (Hystrix cristata) populations, introduced to Italy about 1500 years ago, wh...

In this study SEM and light microscopy were used to investigate the structure of the foliate papillae in the porcupine. The foliate papillae consisted of about 10 or 11 clefts. The length of the foliate papillae averaged 2.79 mm and its width averaged 863 μm. Taste buds were located intraepithelial in the basal half of the papilla grooves (sulcus papillae). Every wall on each fold harboured fro...

In this study the nerves originating from the plexus lumbosacrales of porcupines (Hystrix cristata) were investigated. Four porcupines (two males and two females) were used. The plexus lumbosacrales of animals were appropriately dissected and dissemination of pelvic limb nerves originating from the plexus lumbosacrales was examined. The nerves originated from the plexus lumbosacrales of porcupi...
