Avifauna von Tunis

Florida’s Non-native Avifauna

Florida has a mild climate, diverse natural habitats, and a growing, mobile human population. Florida also hosts thousands of species of introduced plants, fish, and wildlife. A recent compilation lists 196 non-native bird species, comprising 15 orders, which have occurred in Florida. The list includes 72 species of parrots and parakeets (psittaciformes), 51 passerines, and 22 species of waterf...

European avifauna: habitat, migration and endemism

Threats to avifauna on oceanic islands.

Results of the study by Blackburn et al. (2004a) of avifauna on oceanic islands suggest that distance from the mainland and time since European colonization have major influences on species extinctions and that island area is a significant but secondary contributing factor. After augmenting the data of the study on geographical properties for some of the islands they examined, we used a causal ...

Spatial turnover in the global avifauna.

Despite its wide implications for many ecological issues, the global pattern of spatial turnover in the occurrence of species has been little studied, unlike the global pattern of species richness. Here, using a database on the breeding distributions of birds, we present the first global maps of variation in spatial turnover for an entire taxonomic class, a pattern that has to date remained lar...

Tinea Capitis at Charles Nicolle Hospital of Tunis (Tunisia)

Introduction: Tinea capitis is an infection caused by dermatophytes which have a particular affinity for keratin. Its prevalence decreased significantly in developed countries due to the improvement of sanitary conditions and socioeconomic level. However, they are still common in developing countries including Tunisia. The aim of our study was to evaluate the epidemiological, clinical and mycol...
