Supplementation of wild populations with captive-bred organisms is a common practice for conservation of threatened wild populations. Yet it is largely unknown whether such programmes actually help population size recovery. While a negative genetic effect of captive breeding that decreases fitness of captive-bred organisms has been detected, there is no direct evidence for a carry-over effect o...

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...

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...

When escapee farmed Atlantic salmon Salmo salar interbreed with wild fish, the introgression of maladaptive genes can lower population productivity and alter key life history traits. To date, only a few European studies have compared wild, farm, hybrid under common conditions in isolating influence genetics on survival fitness-related Here, we examined performance experimentally derived fry fro...

Photographic identification of individual animals is a non-invasive and cost-effective method that can provide demographic information on wild populations. This study aims to compare two photo-matching algorithms (Wild- ID I3S-Spot) using reintroduced population pool frogs (Pelophylax lessonae) in the UK as case study. We compared following parameters 1) sex age, 2) image quality, 3) collection...
