Diversity and abundance of wild mammals between different accommodation facilities in the Kwakuchinja Wildlife Corridor, Tanzania

Most of the wildlife corridors in Tanzania have been threatened by extensive human activities, including the establishment of tourist’s facilities. However, less attention has been paid to the degree at which tourist accommodation affects the abundance and diversity of wild mammals in wildlife corridors. This study assess the changes in abundance and diversity of wild mammals in relation to proximity to tourist lodges and tented camps in Kwakuchinja Wildlife Corridor. All wild mammals around four randomly selected accommodation facilities that

Key innovations in ruminant evolution: A paleontological perspective

Key innovations are newly acquired structures that permit the performance of a new function and open new adaptive zones, and are, therefore, of paramount significance for understanding the history of the Ruminantia, particularly its diversification through the Miocene. Here we review and discuss what is known about these evolutionary novelties, with special emphasis on the appearance and evolution of cranial appendages and highcrowned (or hypsodont) teeth. Cranial appendages probably favored the diversification of pecorans by being structures strongly related to
