Sentence examples for stage of population from inspiring English sources

Therefore, our population model focuses in the stage of population growth in OSNs.

Little is known about how alien plants that arrive in central Europe from climatically warmer regions cope with the temperature conditions at the early stage of population development.

Here, it is the initial stage of population establishment and persistence which is critical to their ability to spread into natural ecosystems at a later date – sometimes with disastrous consequences.

For A. artemisiifolia, an opportunistic species confined to open, disturbed and nutrient-rich ruderal sites and arable land (Pyšek et al. 2012 a ), the above factors are likely to influence its already rather poor competitive ability (Leskovšek et al. 2012 a ) in regions where temperatures and nutrient supply are suboptimal, and adversely affect the early stage of population establishment.

Plant species distributions are determined by the response of populations to regional climates; however, little is known about how alien plants that arrive in central Europe from climatically warmer regions cope with the temperature conditions at the early stage of population development.

Since the early stage of population development is crucial for determining whether or not a species can successfully establish in a given region (Richardson et al. 2000; Blackburn et al. 2011), knowing the response of seedlings to temperature can greatly improve our understanding of invasion and provide knowledge necessary for the efficient management of invasive species.

We use the population growth function as shown in Eq. 7 to fit the early stages of population growth in three data sets.

We verify our population growth model by estimating the early stages of population growth in three data sets (i.e. first 35 months' population growth of Renren, the first 40 months' population growth of Twitter and the first 14 months' population growth of Gowalla).

In the letter, Kolby said that the unfriendly amphibians in Madagascar are still in the early stages of population growth and suggested several ways to quell the invasion.

Beyond this observation, the models highlight two broad issues in selecting and maintaining cross-feeding as a form of cooperation: selection is sensitive to the dynamical stages of population growth, and some ecologies allow the invasion of exploiting genotypes that work against the evolution of cross-feeding.

The study documents the beginning stages of population divergence among spatial aggregations with recent common ancestry.
