For the gamma scale, total native richness
for each site was calculated as all native species encountered within the sampled quadrats.
The species richness
of planktonic foraminifera of the Maastrichtian Mughal Kot Section is calculated according to Leckie et al.
Several diversity and richness
indices were calculated, amongst them were Shannon Diversity Index and Margalef's Richness
Diversity index is a comprehensive indicator of richness
and evenness and usually associated with the following two factors: 1, the number of species, that is, richness
; 2, the evenness of the individual distribution of species.
Saab (1999) evaluated the impact of vegetation on avian species richness
at three spatial scales (i.e., macrohabitat, landscape, and microhabitat) and found that microhabitat variables correlated most with species richness
In Jun, numbers of bees collected by individual traps ranged from 60 to 1,180, and the observed species richness
collected per trap ranged from 20 to 37, with 1,882 bees and 68 species collected by the 5 traps combined (Table 1).
We have encountered here in the Philippines richness
of the faith.
The species richness
of each category were denoted as NFL, NFt, NbL, Nbt, and the following four measures of species richness
were used in the present study (Foote 2000; Cooper 2004):
 demonstrated that the richness
of gut microbiota increased after RYGB and the variations of bacterial genera were correlated with changes in both clinical phenotype and adipose tissue gene expression.
is a remarkable innovation in taste that brings the time dimension back to prepared foods--recreating the taste complexity from traditional cooking techniques achieved through slow cooking and multi-step cooking processes into a new flavour approach.
The spatial patterns of species richness
and its underlying mechanisms have been one of the hotspots in ecology [1-3].
For example, Faithfull  consistently found lower invertebrate species richness
in kangaroo grassland (Themeda australis) invaded by Chilean needlegrass (Nassella neesiana) compared to uninvaded areas.
Forest composition, species richness
, diversity pattern, and spatial or temporal distribution are important ecological attributes significantly correlated with prevailing environmental as well as anthropogenic variables [3-5].
From 'cava country' in the Penedes region, try The Wine Selection Cava, Spain (PS5, Asda), lively bubbles with good structure and a lemony richness
- and at this price, what's not to love?
A delight from beginning to end, it's rich and aromatic with acacia flowers on the nose, fine lime and citrus flavours with a creamy richness
balanced by refreshing acidity.
