In monotocous mammals (i.e. where females produce one offspring at a time), most juveniles will experience the birth of younger sibling in their life. Transition to siblinghood (TTS) has rarely been studied primates, although it reflects last step shift maternal investment from next and could thus represent critical moment for mother–offspring conflict competition. Here, we used behavioural dat...

Background: Cryptosporidiosis is a zoonotic disease with public health importance, especially for individuals with weak immune system, such as children, elderly people and immune suppressed ones. Evaluation of the prevalence of Cryptosporidium in wild rodents such as wild brown rats could help to establish an epidemiological map of Cryptosporidiosis. The aim of the current study was to assess t...

Bream (Abramis brama orientalis) is one of the most commercially valuable fish in the Caspian Sea. The aim of this study was to compare levels of genetic polymorphism between wild and farmed Bream populations using seven microsatellite loci. Genetic diversity was investigated by studying samples collected from two regions; Chaboksar and the Artificial Propagation Center of Guilan province. Alle...

Secale montanum is one of the important perennial grasses growingnaturally in arid to semiarid pastures and rangelands, with a typical Mediterraneanclimate, in northern and western Iran at altitudes of 800-2900 m. In this paper, seedstorage protein profiles of nine wild populations of S. montanum from differentregions of Iran and their phenotypically superior progenies as well as a multi-origin...

Leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis (VL), is spreading in Iran. Dogs are the main reservoirs but L.infantum has been detected in jackals, foxes and wild rodents too. Despite high number of rodents in the world, the exact role of them in epidemiology of VL is not clear. In recent years the number of sporadic cases of dogs and humans VL has been increased in...

d : We expect that the wild population will have more variation in body weight than the tankreared population because wild fish will encounter different environments out in the ocean, thus contributing more environmental variance to the total phenotypic variance. Unfortunately, the way I wrote the question, it was not clear which population of fish one should be comparing the phenotypic varianc...
