This study was conducted using one hundred and eighty (180) day-old broiler chicks, of Anak strain to assess the levels of inclusion of indomie waste meal as a substitute for maize at 0, 25, 50, 75 and 100%. The birds were randomly assigned to dietary treatments using completely randomized design (CRD). Each treatment contained 3 replicates and each replicate had 6 birds. The study lasted for e...

The UNCCD has been ratified by over 190 countries. It is the attempt by nations, both rich and poor to control the scourge of desertification. The definition of which is “land degradation in arid, semiarid, and dry subhumid areas resulting from various factors, including climatic variations and human activities. It is now widely accepted that desertification is not the relentless advance of des...

Based on a great number of literatures, we established the database about the Chinese endemic seed plants and analyzed the compositions, growth form, distribution and angiosperm original families of them within three big natural areas and seven natural regions. The results indicate that the above characters of Chinese endemic plants take on relative rule at the different geographical scales. Am...

The timing and abruptness of the initiation and termination of the Early Holocene African Humid Period are subjects of ongoing debate, with direct consequences for our understanding of abrupt climate change, paleoenvironments, and early human cultural development. Here, we provide proxy evidence from the Horn of Africa region that documents abrupt transitions into and out of the African Humid P...
