Cause-and-effect interpretations of the apparent impacts of biological invasions are confounded by the coincident occurrence of non-native species and changes to abiotic factors. Native community structure and function can vary greatly in space and time, owing to abiotic variables that could potentially be affected by non-native species. Here, we sought to determine the relative importance of a...
subalpine rangeland as a rara avis ecosystem is very important because ofecological features. consistency and resistance of this ecosystem is so frangible and itsnatural equilibrium is instable due to the effects of biotic and abiotic factors. the landslideas one of negative consequences in upland area is seen in masoleh watershed (north ofiran). this study has investigated the roles of biotic ...
Adaptations to biotic and abiotic stress: Macaranga‐ant plants optimize investment in biotic defence
Abstract: Sulphur dioxide (SO2) is one of the main air pollutants that can cause imbalance in growth and physiological function of plant in high concentrations. Rhizobium-plant symbiosis can cause increasing in plant resistance to abiotic and biotic stresses in addition to increase growth of plant. In this study, effects of Rhizobium (native and standard strains) on leaf anatomical parameter...
Mitogen-activated protein kinase (MAPK) cascades function in biotic and abiotic stress responses in plants. We analysed effect of oxidative stress on the activation of ATMPK6, an Arabidopsis thaliana MAPK, in Arabidopsis T87 cultured cells and rosette leaves using anti-ATMPK6 specific antibody. ATMPK6 in T87 cells was strongly activated by reactive oxygen species (ROS) such as H(2)O(2) and KO(2...
Abbasi Domshahri M. and Ghaderi R. 2019. Causal agents of citrus trees decline in Fars province . Plant Pathology Science 8(1):15-23. DOI: 10.2982/PPS.8.1.15. During recent years, citrus trees decline has becoming one of the most important factors of limiting the area of citrus orchards in the south of Iran including Fars province. Different biotic and abiotic agents were attributed to citr...
Water eutrophication creates unfavorable environmental conditions for submerged macrophytes. In these situations, biotic interactions may be particularly important for explaining and predicting the submerged macrophytes occurrence. Here, we evaluate the roles of biotic interactions in predicting spatial occurrence of submerged macrophytes in 1959 and 2009 for Dianshan Lake in eastern China, whi...
