To further test the generality of BHI-mucin media for community cultivation, we inoculated the other two infant fecal samples into BHI with either 0.4% or 0.6% mucin (Methods). One sample (“FT-2”), collected from a 56-day-old full-term infant, consists of at least 20 bacterial specie...

Likewise, the co-occurrence network of soil methanotrophs was more complex in vegetation-covered areas than in bare land, indicating a more stable community structure. Soil nitrogen, catalase, and plant diversity influence stability and diversity. During the transformation from bare land to plant ...
For many ecosystems, beavers are akeystone species, meaning other animals and plants in the ecosystem couldn’t survive without them. The industrious rodents’ dams create crucial wetland habitat for other species and help raise the water table so plant roots get a steady supply of water. Beavers...

Keystone // Getty Images 1939: Amendments to neutrality acts On Sept. 21, FDR came before Congress to request amendments to a series of neutrality acts so that the United States could send aid to allies in Europe on the verge of a second World War and in opposition of the Nazi regime. ...
This hypothesis is likely more relevant for invertebrate biology than for vertebrate or plant biology because nucleic acids contribute a much higher fraction of organism P in invertebrates than in vertebrates, which contain a substantial fraction of P in bones (Sterner and Elser, 2002), and in ...
Just like Feeney’s (1976) plant apparency hypothesis, which predicts that plants that are more “apparent” to their herbivores should invest broadly in functional defenses, so too should animal societies with conspicuous architecture exhibit more complex defenses against their enemies. For example,...
The Expatriation Act was passed in March of 1907 with a number of impositions, including stipulations that if a woman lived abroad for more than two years or was married to a man who wasn't eligible for citizenship, she could be revoked of her status. The Cable Act of 1922also known as...
Microbial community data are commonly subjected to computational tools such as correlation networks, null models, and dynamic models, with the goal of identifying the ecological processes structuring microbial communities. A major assumption of these met
