A method is described for predicting the spatial distribution of individual birds using presence data. The approach is demonstrated using a statistical habitat association model developed for resident and migratory birds on a 12 ha plot of ponderosa pine (Pinus ponderosa) heavily infested with southwestern ponderosa pine dwarf mistletoe (Arceuthobium vasinatum subsp. Cryptopodum (Englemann) Haw...

Arceuthobium (dwarf mistletoes) are hemiparasites that may cause great damage to infected trees belonging to Pinaceae and Cupressaceae. Currently, dwarf mistletoe control involves the use of the ethylene-producing product ethephon (ETH), which acts by inducing dwarf mistletoe shoot abscission. However, the process by which ETH functions is mostly unknown. Therefore, the transcriptome of the ETH...

The natural hybridization that occurs between two sympatric species of Rhododendron subgenus Hymenanthes in Yunnan, China, was investigated. In field observations, it was noted that the putative hybrids between Rhododendron delavayi (Franch.) and Rhododendron cyanocarpum (Franch.) W.W.Smith had intermediate morphologies. On the basis of morphology, chloroplast DNA (trnL-rpl32) and nuclear DNA (...

Araştırma alanı, Akdeniz Bölgesinin Hatay iline bağlı Yayladağı ilçesi sınırları içerisindedir. Yayladağı, bitki coğrafyası bakımından floristik bölgesine, Davis'in kareleme sistemine göre de C6 karesine dâhildir. Türkiye‟nin en güney noktasının sosyolojisi ve vejetasyon ekolojisini kapsayan bu çalışma, alanın biyolojik çeşitliliği, ekosistem çeşitliliği genetik kaynakların belirlenmesi, korunm...
