Salt stress relief potency of whortleberry extract biopriming in maize
(Springer Heidelberg, 2018)Berries have gained public attention for their presumed positive effects on cancer patients. in contrast, the potential of berries to mitigate damage caused by abiotic stress in plants has not received significant attention. ... -
Potential distribution under different climatic scenarios of climate change of the vulnerable Caucasian salamander (Mertensiella caucasica): A case study of the Caucasus Hotspot
(Springer, 2018)Amphibians are strongly affected by climate change like many vertebrate animals. To address this problematic situation, we examined the potential effect of climate change on the distribution of Mertensiella caucasica (Waga, ... -

Age, survivorship and life expectancy in near eastern fire salamander, salamandra infraimmaculata (Caudata: Salamandridae)
(Maik Nauka/Interperiodica/Springer, 2018)Populations from different environmental habitats indicate variation in life history traits and these differences are mostly related to longevity, age and size at maturity. in this study, age structure, longevity, survivorship ... -
Some azo dyes containing eugenol and guaiacol, synthesis, antioxidant capacity, urease inhibitory properties and anti-helicobacter pylori activity
(Editura Acad Romane, 2018)There are many studies about azo compounds at literature. However, antioxidant capacity, urease inhibitory and anti-Helicobacter pylori activity properties are not well known. Therefore, some azo dyes containing eugenol ... -
