Scatter-hoarding rodents play an important dispersal role for many large-seeded plants. Seed traits affect their foraging behavior; however, it is difficult to isolate their effects because of the covariance among traits. Here, we used artificial seeds to partition the effects of seed size, tannin content, and nutrient content on scatter-hoarding rodents in a natural pine forest in Northwest Yu...
the main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (som) and lowavailability of macro and micro-nutrients. the effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (uswcs) on the chemical properties of a saline-sodic soil was investigated. the experimentwas conducted using a randomized complete block des...
interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...
Polycystic ovary syndrome (PCOS) is a common endocrine abnormality among reproductive-aged women. This study aimed to investigate the relevance of major nutrient patterns and PCOS. Methods: This age-body mass index (BMI) matched case-control study was conducted among 216 women with and without PCOS. The validated 178-items food frequency questionnaire (FFQ) was used for driving nutrient pattern...
Lettuce is one of the major leafy vegetables that is consumed as fresh and salads crops. Although, today, the tendency is to grow lettuce as hydroponic crop, there is not an optimal nutrient solution and growers use different nutrient solutions for growing lettuce. Therefore, an experiment was conducted to find an optimal nutrient solution to grow lettuce. In this experiment, the effect of va...
