The remarkable richness and level of detail preserved at the Moyeni tracksite offer a unique opportunity to investigate the locomotor habits of early dinosaurs.
Furthermore, CCN clade is widely distributed throughout most Neotropical rainforest but present the highest species richness and level of range overlap in the Brazilian Atlantic Forest (BAF) [ 26, 27].
We conducted our research in continental Ecuador, a region that has received considerable conservation focus, because of its high species richness, endemism, and level of threat (e.g. Orme et al. 2005; Finer et al. 2010).
Besides the other attributes favouring molluscs as surrogates or indicators, they have high inherent conservation value, with high local species richness, and high levels of endemism, with relatively narrow distribution ranges [e.g. 47 and references therein], [48].
In marked contrast, both the clonal abundance and levels of OTU richness within phylogroup 6 were significantly lower in the periodontitis group, compared to the periodontitis-free group (p < 0.05).
We analyzed the effectiveness of the Floristic Quality Index (FQI), a vegetative community metric based on species richness and the level of sensitivity to anthropogenic disturbance of individual species present (Coefficient of Conservatism (CC)), using ground layer vegetation data from forests and woodlands with different fire histories in the Missouri Ozarks, USA.
This can be accomplished most directly by obtaining genetic measures from temporally-spaced samples that reflect the overall stability of the population as given by changes in genetic diversity levels (allelic richness and heterozygosity), degree of population differentiation (FST and DEST), and effective population size (Ne).
In our study we make use of the significant benefits that microorganisms offer as model systems to test and inform ecological theory [25] [26] to examine whether interaction effects between bacterial species richness and environmental complexity (resource richness) determine levels of ecosystem functioning over time.
In the 3.5×3.5 m plots that were used for this study, nine dominant plant species from semi-natural, mesophilic grasslands were sown in 2002 as monocultures and mixtures (richness levels of 1, 2, 3, 4, 6, and 9 species [36]).
The Andes are one of the most diverse regions in the world, and traditionally seen as a hotspot for species richness, levels of endemism, and degree of threat (e.g. Sierra et al. 2002; Orme et al. 2005).
