Latitudinal patterns of mammalian species richness in the New World: the effects of sampling method and faunal group Abstract. Although the latitudinal gradient of species richness for mammals in North America is well documented, few investigators have quantified the rela... P Stott,DM Kaufman,MR ...
MethodsWe evaluated bird species richness in 344 forest fragments. Fragment area (FA), distance from the nearest source area (>1000ha) (DSA) and number of neighbouring fragments (NF) were calculated for each fragment. Using Poisson generalized linear models, we compared a model that evaluated ...
forests combining different tree species at the stand scale, is a relevant adaptation strategy in the face of climate change and its associated pressures (Messier et al., 2022) due to two main advantages. First, mixing species may create an “insurance effect” in case one species declines. ...
Insect activity, however, was different between the cadaver types, as previous research using the same cadavers as this experiment showed differences in species richness of insects, particularly in Diptera between pigs and humans [38]. Insects have the ability to remove a significant amount of ...
(i.e.a). The final network is obtained after having allowed 100 times in a row, a randomly chosen individual to disconnect (or reconnect) from one of its neighbors, also randomly chosen. The averages and standard deviations were calculated from the results obtained for the 24 ...
i.e. to variation in SShD that is due to body size (allometric) and variation that is independent of size (non-allometric). Body height was used as a measure of an individual’s size. The allometric variation in SShD was calculated by regressing the original facial coordinates on height an...
In live-bearing animal lineages, the evolution of the placenta is predicted to create an arena for genomic conflict during pregnancy, drive patterns of male sexual selection, and increase the rate of speciation. Here we test these predictions of the vivi
In statistical outlier removal (SOR) the mean distance to theknearest neighbors is calculated for each point. Points are removed if the mean distance surpasses a certain threshold which is based on the global mean distance to theknearest neighbors and the standard deviation of the mean distances...
In order to gain insights into the genetic diversity of the reproducing individuals in the three core areas, we calculated the mean number of alleles (Na), number of effective alleles (Ne), allelic richness (Ar), observed heterozygosity (Ho) and unbiased expected heterozygosity (He) for the ...
The easiest way to count unique values in a column is to use the UNIQUE function together with theCOUNTAfunction: COUNTA(UNIQUE(range)) The formula works with this simple logic: UNIQUE returns an array of unique entries, and COUNTA counts all the elements of the array. ...
