This study aimed to reveal the diversity of aphid species and aphid-plant interactions adjacent Çardak Lagoon, which is close agricultural areas in Çanakkale Province Turkey. Twenty-seven belonging 17 genera three subfamilies from Aphididae (Hemiptera) were identified. Of these, Staticobium latifoliae (Bozhko, 1950) new record genus Mordvilko, 1914 Aphis symphyti Schrank, 1801 are records for f...

Adaptations of Abies nordmanniana, Picea orientalis, Pinus sylvestris, Fagus and Carpinus betulus to the abiotic environmental conditions study area largely determined their predicted distribution in Caucasus. The ecological niches species mostly coincided two analyzed complex factors (characteristics water regime topographic parameters). humidity factor was main determining potential forest-fo...

Understanding climate change impacts on drought-prone forests is a critical issue. We investigated ring-width and stable isotopes (∆13C and δ18O) in two Pinus sylvestris stands of the cold–dry Siberian forest–steppe growing under contrasting climatic trends over the last 75 years. Despite regional warming, there was increasing precipitation during the growing period at the southern site (MIN) b...

The ability of a population to genetically adapt to a changing environment is contingent not only on the level of existing genetic variation within that population, but also on the gene flow received from differently adapted populations. Effective pollen-mediated gene flow among plant populations requires synchrony of flowering. Therefore differences in timing of flowering among genetically div...

Our objective was to test whether or not plastids and mitochondria, the two DNA-containing organelles, move between cells in plants. As our experimental approach, we grafted two different species of tobacco, Nicotiana tabacum and Nicotiana sylvestris. Grafting triggers formation of new cell-to-cell contacts, creating an opportunity to detect cell-to-cell organelle movement between the genetical...

Casearia sylvestris (Salicaceae), popularly known as "guaçatonga", is a plant widely used in folk medicine to treat various diseases, including cancer. The present work deals with the chemical composition as well as the cytotoxic evaluation of its essential oil, its main constituent and derivatives. Thus, the crude essential oil from leaves of C. sylvestris was obtained using a Clevenger type a...

Many trees species form symbiotic associations with ectomycorrhizal (ECM) fungi, which improve nutrient and water acquisition of their host. Until now it is unclear whether the species richness of ECM fungi is beneficial for tree seedling performance, be it during moist conditions or drought. We performed a pot experiment using Pinus sylvestris seedlings inoculated with four selected ECM fungi ...

Widespread afforestation programs sequester carbon from the atmosphere and mitigate the rising of atmospheric carbon dioxide (CO2). Meanwhile, afforestation carbon sequestration may cost soil water. However, changes in soil moisture content (SMC) after large-scale afforestation or reforestation have rarely been quantified. In this study, we measured changes in SMC following afforestation using ...

This study investigates stable carbon and hydrogen isotope compositions of leaf wax n-alkanes from 3 angiosperm and 2 conifer species from a semi-desert natural environment. The dC and dD n-C27 alkane data show a clear distinction between Populus tremuloides/Syringa vulgaris ( 31.9 to 32.7‰ and 168 to 186‰, respectively) and Pinus sylvestris/ Picea pungens ( 28.8 to 30.6‰ and 190 to 212‰) throu...

Crop-to-wild gene flow have important evolutionary and ecological consequences and require careful consideration in conservation programs for wild genetic resources of potential use in breeding programs and in assessments of the risk of transgene escape into natural ecosystems. Using 26 microsatellites and a set of 1181 trees, we investigated the extent of introgression from the cultivated appl...
