Sentence examples for richness trend from inspiring English sources

Discriminating which variable is responsible for the observed richness trend, given that a single variable exists, is problematic considering that most variables are correlated (e.g., wave stress and depth, stratification and temperature).

This mixture of cold- and warm-water species particularly in the deeper, northern parts of the North Sea could partly explain the latitudinal species richness trend, especially in the offshore areas.

Rodent species richness trended higher with increasing shrub cover in five of six site-type/year combinations, but none of the correlations were significant.

Fisher's α diversity and species richness trends were very similar to past sampling in these kinds of forests (Myster 2010).

With standardized breeding bird observation data of five years within 2001 2014 from six sites in Central Germany we investigated whether trends in bird abundance are reflected by trends in species richness and whether these trends depend on the landscape context.

We compared the performance of a proposed habitat surrogate for birds, percentage cover of vegetation overstory, for two distinct aspects of bird assemblages: community diversity (i.e. species richness) and population trends.

This result is similar to that seen for both assemblage structure [56] and species richness and evenness trends [23] in west coast demersal fishes.

The association between avian and mammal richness and latitudinal trends in diversity were explored by second order polynomic regressions [ 51].

These were also the two groups that showed non directional trends in species richness as well as phylogenetic trends along habitat recovery gradients.

Species richness follows a general trend among cover types of: hardwood ≥ regenerating forest, hardwood pine, and pine ≥ mixed ≥ hardwood hemlock > hemlock.

Land cover variables differed in their effects on the species richness of the three trend categories: the amount of grassland had the greatest positive effect on the number of declining species, whereas the amount of forest was the most important land cover variable for species richness of stable butterflies and arable land and field-forest mosaic for species richness of increasing butterflies.
