Biological nitrogen fixation (BNF) plays a vital role in supply agricultural ecosystem but is generally impaired by fertilization. Understanding the trade-off between fertilization and BNF, underlying mechanisms are essential to optimize management for sustainable agriculture production. In this study, we examined potential rate of asymbiotic N2 fixation, nifH gene abundance, composition co-occ...
BACKGROUND Minimal stimulation in vitro fertilization (mini-in vitro fertilization) is an alternative in vitro fertilization treatment protocol that may reduce ovarian hyperstimulation syndrome, multiple pregnancy rates, and cost while retaining high live birth rates. OBJECTIVE We performed a randomized noninferiority controlled trial with a prespecified border of 10% that compared 1 cycle of...
Marine reserves have become widely used in biodiversity conservation and are increasingly proposed as fisheries management tools. Previous modeling studies have found that reserves may increase or decrease yields, depending on local environmental conditions and on the specific life-history traits of the fishery species. Sex-changing (female-to-male) fish are targets of some of the most importan...
