Two primary factors - location within the watershed (i.e., geographic position, stream order, and distance to a downstream confluence) and percentage of urban land cover (both scales) - emerged as important predictor variables. Latitude and longitude interacted with other factors to explain the ...
Sexual reproduction is a fundamental biological process that creates novel and beneficial allelic combinations by bringing together and mixing maternal and paternal gametes [1]. In most animals, sexual reproduction has led to the evolution of separate sexes, whereas among angiosperm plants only about 5%...
In this study, we investigate the genetic and ecological drivers underlying the evolution of Serratia marcescens, an opportunistic pathogen with high genomic flexibility and able to colonise diverse environments. Comparative genomic analyses reveal a population structure composed of five deeply-demarcated ge...

and evolution1,2. Clearly, the adaptive capacity of an animal species is not determined solely by the host genome but must also include the vast genetic repertoire of the microbiome3. Concretely understanding how environmental perturbations, host–microbe coevolution, and other factors dictate the ...
While waiting, I noticed that the young father was holding his money tightly and nervously. Theyoung mother was carrying a baby in her arms and asked the cashier (收银员) for a job application. When the total was rung up, they had to pick items out of their cart because they didn’t...
Here we show how the problem of understanding these oscillations may be cast as a predator-prey problem, with electrons as prey and particles as predators. The addition of a nonlinear loss term to the classic Lotka-Volterra equations used for describing the predator-prey problem in ecology not ...
