Aims Both human and non-human determinants have shaped Mediterranean forest structure over the last few millennia. The effects of recent human activities on forest composition, however, remain poorly understood. We quantified changes in forest composition during the past century in the mixed forests of Quercus suber (cork oak) and Q. canariensis (Algerian oak), and explored the effects of fores...
دو گونه Lotus aegaeus و Phalaris canariensis که اولی از استان آذربایجانغربی و دومی از استان کردستان و استان تهران جمعآوری شدهاند برای اولین بار از ایران گزارش میگردند. تصویرگونهها به همراه شرح آنها نیز تهیه شده و در این مقاله ارایه میگردد.
A study was designed to provide information about the best plantation techniques for Pinus canariensis in the southern part of Tenerife, at the old pine forest location (precipitation <250mm and 12oC mean annual temperature). Two study sites were selected (Fasnia and Arico); in each site two plots of 5 ha were established. In total, 4 plots were located and in each plot, 32 subplots of 16 x 16 ...
The effect of extreme temperature on the quantum yield of fluorescence and membrane leakage of Pinus canariensis growing in 5 stands at different altitudes and orientation in Tenerife (Canary Islands, Spain) was determined. Needles were collected from the field and transferred to the laboratory where they were kept in a closed chamber with water-saturated air overnight. Then they were exposed f...

Chloroplast microsatellites are becoming increasingly popular markers for population genetic studies in plants, but there has been little focus on their potential for demographic inference. In this work the utility of chloroplast microsatellites for the study of population expansions was explored. First, we investigated the power of mismatch distribution analysis and the F(S) test with coalesce...
