1A1), with species richness (s) first increasing along with increasing plant productivity (P) and then decreasing. The dynamics of Sp show the sunken form (Fig. 1A2). The reason for the sunken Sp is that when s gradually increases, the actual contribution of the species pool to the ...
A study with substantially more genetic loci (352 markers) did not increase support for its position within the family28. Fig. 1: Time-calibrated phylogenetic tree of brush-footed butterflies (Nymphalidae) with biogeographic distribution of extant species and branch net diversification rate estimated ...
For the following questions, either draw a graph with given specifications or explain why no such graph exists. 1) Graph: connected, with seven vertices and seven edges. 2) Tree: with eight vertices a Give an example (by drawing or by describing) of...
for example, have to cope with water backing up behind them (their abutments often have strategically placed openings to let high flood water drain through). Suspension bridges that carry cars tend to bear the same loads all day long, though, often sited in windy estuaries, they also have ...
Accordingly, the number of connections in comparison with the minimum spanning tree is low, there is a low number of triangles in the network and they do not tend to share vertices. The instances of roads and power networks that have similar values for the second principal component have a ...
a The completed CART decision tree with pathways marked in the terminal leaves. b Example pathways for each level of spatial inequality in property flood risk. The histogram shows the feature space distribution of the five levels of spatial inequality in property flood risk. We use a stacked his...
We hypothesized that the deletion junction unique to our index case plays a role in regulating splicing of the upstream exon 44, and tested it using the Drosophila sex determination system—a classic example of how splicing factors exert specific control of splicing.34 This system has been used ...
For example, in the forest pest Dendroctonus frontalis Zimmerman (Coleoptera: Scolytinae) (the southern pine beetle), winter severity explained a sizeable portion of the variation associated with population dynamics in northern but not southern locations5. In the same study, it was demonstrated that ...
The complexity of the tumor microenvironment context makes it difficult to use the TIME to assess prognosis, as demonstrated by the example of regulatory T cells (Tregs). The effect of Tregs on prognosis is ambiguous, with different studies considering them to be negative, positive or neutral. ...
For example, perhaps OPR and ADR evolved from a common ancestral, aminergic receptor with the somatostating and neuropeptides B/W receptor evolving from the OPR. Or perhaps the OPR evolved from the somatostatin or neuropeptide B/W receptors through a common peptide receptor ancestor. The ...
