Only one feature can be considered to be common to all species, namely that their members are always linked by a relation of ancestry and descent. This led de Queiroz[7,8]to propose a generallineagespecies concept, which defines species as “separately evolving metapopulation lineages”. Although...
Theopederin D, nazumamide, and several onnamide and aurantoside congeners, as well as the keramamides, were only detected in the whole sponge extract (however, note that keramamides were detected in the 'Entotheonella' sample using a more sensitive mass spectrometry method; see Supplementary ...
Results: DeSignate is a tool for character-based taxon diagnoses that includes a novel ranking scheme. It detects and classifies individual and combined signature characters (diagnostic molecular characters) based on so-called character state vectors. An intuitive web application guides the user through...
indicate considerable strain to strain chemical and genetic diversity. Bioassay-guided fractionation of one active extract has led to the isolation of a novel series of metabolites that includes a potent cytotoxin (IC50=10 ng/ml against the HCT-116 human colon carcinoma cell line) that has been ...
We ran a test which showed that the model with one common slope and separate intercepts for each of six of the major groups of endotherms best fits the dataset. Thus, we obtained three versions, independent of both the size of the animal and of the BMR in different clades of endotherms,...
Δln𝐿𝑇a𝑖ΔlnLiTa will be positive for sites that favor Ta and negative if one (or more) of the other candidate topologies is favored relative to Ta. We examined three candidate topologies for this study, but Equation (1) can be used for any number of candidate topologies. We ...
The variable that decreased the gain the most when omitted was BIO4, which appeared to have the most information compared to the others. The results of the Jackknife test also showed that using one variable did not exceed the gain of using all variables, indicating that each variable ...
It is important to note that only one introduced species was recorded in these surveys, the east Australian scallop Scaeochlamys livida [50]. This species is now established in Western Australia and was recorded at both reefs (based on dead valves). While increased incidence and movement of ...
