Abstract

Biological invasions have caused considerable disruption to native ecosystems throughout the world through predation, habitat alteration, competition and hybridisation with native species and introduction of diseases or parasites. Species of the genus Carassius [C. auratus (Linnaeus, 1758), C. carassius (Linnaeus, 1758) and C. gibelio (Bloch, 1782)] were transported to numerous inland water bodies throughout Turkey. Species are now considered a threat factor for native species. The purpose of this study is to review the current distribution and ecological impacts of species in the inland waters of Turkey.

Highlights

  • Ethiopia spans a remarkable number of the world’s broad ecological regions due to its dramatic geological history, broad latitudinal spread and immense altitudinal range

  • The results showed the greater abundance of Parthenium hysterophorus L., Cryptostegia grandiflora Roxb. ex R

  • In addition to the natural threats to biodiversity such as: wildfire, drought, bush encroachment and others; anthropogenic factors such as settlement within the Park, agricultural expansion, grazing and browsing by domestic animals, deforestation, illegal charcoal production and fire wood collection are the major threats to the Awash National Park (ANP)

Summary

Introduction

Ethiopia spans a remarkable number of the world’s broad ecological regions due to its dramatic geological history, broad latitudinal spread and immense altitudinal range. This range from the depressions in the Afar (126 m below sea level) to the spectacular mountaintops of Ras Dashen in the north (4620 m) and the Bale Mountains in southeast Ethiopia (4272 m). This variety of habitats supports a rich variety of different species which contributes to the overall biodiversity of the country (IBC 2005). That is why protected areas form a central element of any national strategy to conserve biodiversity
