Abstract
Identifying rat and mouse species quickly, affordably, and accurately is crucial for effective populationmanagement, as well as for eradication or conservation purposes. However, the sheer diversity of these species poses achallenge. To address this, a molecular approach has been developed, involving the amplification of a short genetic markerfrom materials commonly left by the animal, such as hairs and feces. Recent available PCR primers were not suitable read more

Saat ini beberapa jenis pohon tropika, seperti jati, pinus dan meranti berhasil tumbuh sangat cepat. Produktivitas dan pertambahan volume pohon atau riap tegakan semakin besar per satuan waktunya. Pertumbuhan yang begitu mengesankan tersebut berkat penelitian dan inovasi bidang pemuliaan pohon. Sebelum ini, hasil penebangan pohon jati biasa pada akhir daur dengan rerata umur 40 tahun hanya mencapai 68,7 meter kubik per hektar. Sementara itu, setelah penemuan klon jati unggul yang secara komersial read more
