Sentence examples for ecological strain from inspiring English sources

At each point along the way he finds varying mixtures of economic dynamism, cultural diversity, ethnic tension, ecological strain and political turmoil.

Their conclusion is relatively simple: "Two important features seem to appear across societies that have collapsed: (1) Ecological Strain and (2) Economic Stratification".

The most straightforward explanation would be the ST60 strains shared similar ecological niches with strains in CC11, because DNA exchange tends to take place among strains in similar environments or ecological niches (Jain et al. 2003; Didelot et al. 2012).

To shed light on the intraspecific mitochondrial evolution in L. kluyveri and compare the effects of geographical vs. ecological origins on strain diversity, we investigated the phylogenetic relationships among the strains surveyed.

Experiments in Lactobacillus-free mice to measure the ecological fitness of strains originating from different hosts supported host adaptation, as only rodent strains colonised mice efficiently [ 15].

Considering this, one may speculate that the phenotypic disparities (tissue tropism, virulence and ecological success) among strains are encoded in a small number of variable genes along the C. trachomatis genome.

There is a possibility that the ST60 strains shared ecological niches with some CC11 serogroup C strains and recurrent homologous recombination of each ST60 strain with the CC11 strains has taken place after the split of the two ST60 strains.

The gene-based phylogeny was not fully consistent with the traditional classification into dairy and non-dairy strains but supported a new classification based on ecological separation between "environmental" strains, the main contributors to the genetic diversity within the subspecies, and "domesticated" strains, subject to recent genetic bottlenecks.

The genetic stability and ecological persistence of a strain of the filamentous fungus, Trichoderma virens, genetically modified (GM) with a hygromycin resistance gene and a gene encoding an organophosphohydrolase was evaluated over 243 days in soil mesocosms.

This is the first study done with regard to interaction between strain and ecological variables on type B trichothecene production by isolates of these two species from crops grown in Spain.

However, our findings also highlight the importance of healthcare environments and local ecological exposures in shaping strain dynamics, which may limit generalisability of specific associations.
