Species diversity is the number of different species that are represented in a given community. The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest. What is the m...
The AI industry is selling that smiley face hard. Consider howTheDaily Showrecently skewered the hype, as expressed by industry leaders. Silicon Valley’s VC in chief, Marc Andreessen: “This has the potential to make life much better … I think it’s honestly a layup.” Altman: “I hat...
We conclude that more exploration of species' abundance distributions is necessary and we suggest methods to use in future studies.doi:10.1046/j.1461-0248.2002.00297.xRaphael D. Sagarin1 Hopkins Marine Station of Stanford University, Pacific Grove, CA 93950, U.S.A. E‐mail: sagarin@stanford...

[#highlight6]That we now have an abundance of the proof that was called for was established when Barbara Bentley reviewed the relevant evidence in 1977, and since then many more observations and experiments have provided still further proof that ants benefit plants.[/highlight6] [#paragraph4]...
We used an individual based simulation model to predict how species traits influence the scale of effect. Specifically, we tested the effects of dispersal distance, reproductive rate, and informed movement behavior on the radius at which percent habitat cover best predicts population abundance in a ...

Overall, organic farming showed higher species richness or abundance in 58% of the pairs. No differences were found for 38%, 4% indicated negative effects from organic farming. The average (median) species numbers of flora on arable land were 95% higher under organic management as well as 61...
However, the north side of Cayman Brac in the Cayman Islands is dominated seasonally by the green macroalga Microdictyon (percent cover of Microdictyon is 4% in the winter and ~40% of the reef in the summer), although it is absent from the south side of the island and the remainder ...
Abundance Degree of plentifulness "Species of low abundance are ignored in the calculation of predominance" (William M. Lewis). Plenty Sufficiently; very It's plenty hot. Abundance (Chemistry) The amount of an isotope of an element that exists in nature, usually expressed as a percentage of ...
