Nutrient pulses can facilitate species establishment and spread in new habitats, particularly when one species more effectively uses that nutrient pulse. Biological differences in nutrient acquisition between native and exotic species may facilitate invasions into a variety of habitats including deciduous forest understories. Alliaria petiolata (Bieb.) Cavara & Grande is an important invader of...

The competitive exclusion principle (CEP) states that no equilibrium is possible if n species exploit fewer than n resources. This principle does not appear to hold in nature, where high biodiversity is commonly observed, even in seemingly homeogenous habitats. Although various mechanisms, such as spatial heterogeneity or chaotic fluctuations, have been proposed to explain this coexistence, non...

The craft brewery industry is growing in the United States. Due to changes state law over past 10 years, breweries are a relatively new Oklahoma. A unique aspect of compared larger that tend be grounded their local communities. purpose this research was understand how Oklahoma establish brand with respect Interviews were conducted personnel across Oklahoma, including participants from both more...

An understanding of the fundamental causes of the structure of primate communities is important for studies of primate evolutionary history, primate behavioral ecology, and development of conservation strategies. Research into these structuring factors has benefited from new perspectives such as consideration of primate phylogenetic history, metacommunities, and interactions with predators and ...

It has been widely assumed that the ecological function of antibiotics in nature is fighting against competitors. This made them a good example of the Darwinian struggle-for-life in the microbial world. Based on this idea, it also has been believed that antibiotics, even at subinhibitory concentrations, reduce virulence of bacterial pathogens. Herein, using a combination of genomic and function...

An important type of product differentiation in the venture capital (VC) market is industry specialization. We estimate a market structure model to assess competition among VCs—some of which specialize in a particular industry and others of which are generalists—and find that the incremental effect of additional same-type competitors increases as the number of same-type competitors increases. F...
