Nests are one of the most creatively made shelters among the animal world; so much so that their creativity even rivals that of the average modern birdhouse. So let’s have a look in different types of nests of differentbird species. If you have a love for birds or you are an ornitholo...
Yeast speciesMicrobial signatureCandidiasisVultures have evolved adaptive mechanisms to prevent infections associated with their scavenging lifestyle. However, food-borne exposure to antimicrobial pharmaceuticals can promote opportunistic infections with adverse outcomes. Here, we used multivariate and network ...
them to exploit large areas. Thus, the ecosystem functions in which they are involved and the services they provide probably develop at spatial scales of unknown range6,24,25. In fact, it has been postulated that the most specialist group of species (Gypsspp.) evolved in a context of resou...
Eagles are large birds of prey that belong, along with birds such ashawksandOld World vultures, in the family Accipitridae. Eagles are found on every continent except for Antarctica. There are around 60 species of eagle. They are often divided into four main types:fish eagles(including thewhit...
It was concluded that most concentrations compared well with those reported for other avian species, but concentrations of Cr, Ni and Pb in the dead vultures were generally above values characteristic of heavy metal poisoning. The values reported for each of two wild populations of P. africanus ...
While transferring tsetse habitat models between regions has not yet been attempted, there have been previous attempts for other plant and animal species with varying degrees of success. For example, fish distribution models transferred between two areas in southwest Finland had good Area Under Curve ...
For example, the Everglades kite (a small hawk) feeds on just one species of snail, and many feather mites can survive on just one species of bird. Behavioral ecologists who study feeding strategies are often concerned with theories of optimal foraging. Obviously, animals must gain more energy...
in areas with a less strict regime of protection. Interestingly, large-sized species flew at longer distance than small-sized species. These findings have important implications for management to reduce disturbance to avian wildlife by human activities and to assess the effectiveness of protected areas...
MPI of the eleven studied metals in both liver and kidney of the studied species decreased in the order Qillin (24.36) > Abu Rawash (17.98) > Toukh (3.90). In the three investigated localities, the overall calculated MPI values were higher than one, indicating that the ecosystem...
