Soil protists: a fertile frontier in soil biology research.
Protists include all eukaryotes except plants, fungi and animals. They are an essential, yet often forgotten, component of the soil microbiome. Method developments have now furthered our understanding of the real taxonomic and functional diversity of soil protists. They occupy key roles in microbial foodwebs as consumers of bacteria, fungi and other small eukaryotes. As parasites of plants, ani...
متن کاملMaternal obesity and fetal metabolic programming: a fertile epigenetic soil.
The incidence of obesity and overweight has reached epidemic levels in the United States and developed countries worldwide. Even more alarming is the increasing prevalence of metabolic diseases in younger children and adolescents. Infants born to obese, overweight, and diabetic mothers (even when normal weight) have increased adiposity and are at increased risk of later metabolic disease. In ad...
متن کاملCLIMATE CHANGE: Will Warmer Soil Be as Fertile?
Thick smoke routinely cloaks Southern California hills, highways, and neighborhoods during this region’s autumn wildfire season, with drought contributing to worse fires than usual in the past two years. Wildfire emissions generate larger aerosols than those produced by vehicles—up to 0.4 micrometers (μm) in diameter compared with less than 0.15 μm—according to a new study led by Constantinos S...
متن کاملIce nucleation by fertile soil dusts: relative importance of mineral and biogenic components
Agricultural dust emissions have been estimated to contribute around 20 % to the global dust burden. In contrast to dusts from arid source regions, the ice-nucleating abilities of which have been relatively well studied, soil dusts from fertile sources often contain a substantial fraction of organic matter. Using an experimental methodology which is sensitive to a wide range of ice nucleation e...
متن کاملDefective Soil for a Fertile Seed? Altered Endometrial Development Is Detrimental to Pregnancy Success
BACKGROUND Synchronous development of the endometrium (to achieve a receptive state) and of the embryo is essential for successful implantation and ongoing pregnancy. Endometrial receptivity exists only for a finite time in a menstrual cycle and the endometrium is refractory to embryo implantation outside of this window. Administration of hormones to stimulate multifollicular development within...
