Chaetophiloscia cellaria and Porcellio laevis are the most abundant species; their relative abundance is respectively equal to 29.5 and 23.4 %. The species richness varied from 8 in both lagoons of Ghar El Meleh and Bizerte to 1 in... H Khemaissia,C Souty-Grosset,K Nasri-Ammar 被引量:...
Species Diversity issimply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term 'biodiversity'. What is speci...
Malthus predicted that natural population growth would inevitably outpace agricultural output, ultimately resulting in famine and other catastrophes until the population was reduced below a sustainable level. The cycle is endless, he believed: Relative abundance causes an increase in fertility until the po...

This leaves the remaining genes without enough reagents to amplify properly, and the Ct value recorded will not reflect actual abundance. Fortunately, this problem has a simple solution: primer limitation, which involves running the assay for the more abundant gene with...
This abundance of data challenges the memory limits of scientists’s workstations and requires imaging software that is optimized for handling such high-resolution, multi-channel, and time series imaging data. The new Xplore5D extension for Amira Software allows cell biologists...
Metals: You’ll typically encounter metal commodities under a sole umbrella term, or split into two further categories — precious metals and common metals. Gold and silver are examples of precious metals, while copper is considered common due to its relative abundance. ...
About 50 percent of the species on Earth became extinct, including many other large reptiles, like pterosaurs and plesiosaurus, as well as lots of plant species and marine animals. Other life forms, such as ferns, flourished by taking advantage of the sudden abundance of natural resources. ...
All methods were similarly poor at estimating relative abundance for rare species, but PI and VC were substantially better at high abundances. Differences among methods were larger than among observers. Our results suggest that SF is best when the monitoring focus is on rare species or species ...
Another phytohormone that consistently drives anthocyanin accumulation in different plant species is abscisic acid (ABA; Loreti et al., 2008; Shen et al., 2014; An et al., 2018). In apple, this involves, for example, ABSCISIC-INSENSITIVE 5 (ABI5), which directly regulates bHLH3 expression,...
