The degree to which biocontrol agents impact invasive plants varies widely across landscapes, often for unknown reasons. Understanding this variability can help optimize invasive species management while also informing our understanding of trophic linkages. To address these issues, we tested three hypotheses with contrasting predictions regarding the likelihood of biocontrol success. (1) The bi...
nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...
Recent studies have provided evidence that trade-offs in biomass allocation, resource-use efficiency, and anti-herbivore defense influence seedling performance and distribution across soil types. Our previous research suggested that soil nutrient availability acted as a filter for understory palm community assembly and species coexistence in a lower montane forest in western Panama. Here, we ex...
The definition of soil quality encompasses physical, chemical and biological characteristics, and it is related to fertility and soil health. Many indicators can be used to describe soil quality, but it is important to take into account sensitivity, required time, and related properties, than can be explained. Properties related to organic matter content, such as C/N ratio, organic carbon fract...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...
This study was conducted to assess the nutritive value and performance of green fodder (GF) production in hydroponic system. A mixture of barley (100 kg) and corn (80 kg) seeds was prepared and grown in an automatic controlling growing chamber that contained 7 shelevs, each with 16 special trays capacity. From each shelf, 6 trays were taken out after 7, 8, 9 and 10 days (as treatment) and ...
• Some O horizons showed higher nitrification rate than mineral horizons. Both total N and pH were positively correlated with in horizon. Nutrient richness litters supported active Nitrification horizon increased along a threshold of 5.5–6.0. High nitrate leaching has been observed from the some tropical forests; however, drivers high production (active nitrification) these have not yet identif...
