Sentence examples for at these shallow levels from inspiring English sources

We, therefore, developed an automated supermatrix procedure to infer phylogenies for a large sample of vertebrate diversity targeted at these shallow levels of divergence (see Methods section and Additional File 1).

Especially at this shallow level of divergence, it is likely that multiple processes such as demography and incomplete lineage sorting influence the gene genealogies and the implementation of a method that properly accommodates this variation, rather than a concatenation approach, becomes especially relevant [ 89, 90] and references therein.

To complete the picture, especially at the shallowest levels of the Earth's crust, it would help to have a network of seismometers at sea as well.That is what Frederik Simons of Princeton University and his colleagues are proposing to create.

Further, these recommendations apply to studies at relatively shallow levels of diversity (generally at the family level and below).

For this type of phreatic activity observed at these and other volcanoes, the presence of magma at shallow levels appears to exert a significant influence on the overlying hydrothermal or groundwater system.

In regions with high surface heat flow, such as areas of active volcanism or mantle upwelling beneath thinned continental crust, geothermal gradients of 40 to 100 °C (104 to 212 °F) per kilometre (0.6 mile) prevail, giving rise to high temperatures at relatively shallow levels of the crust.

The diagram suggests emplacement of andalusite granites at relatively shallow levels in the Asbestos ophiolite, and possibly through peridotites that were already serpentinized.

This hydrothermal system is situated at comparatively shallow levels (probably less than 1 km deep), allowing mixing to occur between magmatic fluids from below and meteoric fluids percolating downward from above.

Nevertheless, because the molecular data of this paper all derive from mitochondrial DNA, we cannot absolutely exclude that the tree is influenced by introgression at very shallow levels.

The MT inversion of the present study suggests that at shallow levels, resistivity structure changed at around March 2012, and accordingly, we interpret these changes in resistivity to be the result of the upward migration of volatiles, which may originated from magma degassing.

The apparent equilibrium temperature of fumarolic gases estimated from the sulfur reaction suggests that the volcanic gases at shallow levels under the Jigokudani valley are present at temperatures of 200°C to 340°C (Mizutani et al. 2000).
