No-tillage (NT) has been one of the main advances related to soil management in Brazilian agriculture last 30 years. However, its full adoption lowland areas that are traditionally cultivated with flooded rice is still incipient (<5 %). The reasons associated hydromorphic condition and highly recalcitrant residual crop biomass, demanding disturbance even occasionally. This review presents a his...

background: although upper-extremity disability correlates with psychosocial aspects of illness the association with sleep disturbance in upper extremity disability is less certain. to evaluate whether sleep disturbance is associated with upper-extremity disability among patients with upper extremity illness, accounting for sociodemographic, condition-related, and psychosocial factors. methods:...

background: heavy menstrual bleeding of endometrial origin (hmb) is a major healthcare problem in premenopausal women and affects several aspects of women’s health and quality of life (qol). the aim of this study was to compare the efficacy of persian golnar (pg) and tranexamic acid (ta) on heavy menstrual bleeding of endometrial origin (hmb) and patients’ qol. methods : a double-blind randomiz...

Gene flow is an essential component of population adaptation and species evolution. Understanding of the natural and anthropogenic factors affecting gene flow is also critical for the development of appropriate management, breeding, and conservation programs. Here, we explored the natural and anthropogenic factors impacting crop-to-wild and within wild gene flow in apples in Europe using an unp...

Changing climatic conditions impose a challenge both to biodiversity and food security. The effects of climate change affect different aspects of the plant or crop, such as morphological and phenological aspects, as well as yield. The effects of greenhouse conditions might be comparable in some cases to a permanent extreme disturbance in climate and weather, thus, contributing to our knowledge ...

Herbivores can often control plant dynamics by mediating positive feedbacks in plant species’ influence on nutrient cycling. In a 7-yr field experiment in a nitrogenlimited Minnesota oak savanna, we tested whether herbivores accelerated or decelerated nitrogen (N) cycling through their effects on plants. We measured effects of excluding insect (primarily Orthoptera and Homoptera) and mammalian ...

Biological diversity could enhance ecosystem service provision by increasing the mean level of services provided, and/or by providing more consistent (stable) services over space and time. Ecological theory predicts that when an ecosystem service is provided by many species, it will be stabilized against disturbance by a variety of 'stabilizing mechanisms.' However, few studies have investigate...
