Nevertheless, in general the rate of photographing an animal at camera traps is correlated with animal abundance and thus provides a useful index of species occurrence at a location [32], [33], but see [34].
To quantify diet composition, we used the indexes of frequency of occurrence (%FO) and average per cent abundance (% N) [ 18] (figure 1 b).
For each pair, I calculated Schoener's index of co-occurrence C ij, a measure of co-occurrence that takes into account the presence or absence of species at each site, as well as their proportional abundances [ 46].
Indices like total number of occurrence of each codon, RSCU [ 61], codon adaptive index (CAI) [ 61], amino acids frequencies, average hydrophobicity (Gravy score) [ 34, 47], aromaticity [ 62], aliphatic index [ 63] and mean molecular weight (MMW) of protein coding sequences were calculated to find out the factors influencing codon and amino acid usage.
CCME WQI results (Fig. 8) indicated the frequency of occurrence of water quality index.
By dodging the chasing, shoe‑throwing ground staff and forcing the umpires to call an early tea, the mongrel booked its place in Wisden's index of unusual occurrences.
A typical copy would also include several pages of articles and features about topical issues in cricket, profiles of the five Wisden Cricketers of the Year, obituaries, records, rules and an Index of Unusual Occurrences bearing headlines such as "Rabbit burns down pavilion", "Hot-air balloons stop play" or "Cricketers arrested for dancing naked".
I used Schoener's index of co-occurrence ('cij' [40]), following reference [7].
We used a hierarchical agglomerative clustering strategy and Ward's linkage method with Euclidean distances to determine relatedness (i.e., a statistical index of co-occurrence) among species presence.
53 The global index of co-occurrence analysis presented five main themes.
