To encourage widespread sampling of the two programs, Discovery simulcast them on four other channels on Monday night: Discovery Fit & Health Investigation Discoveryy; Planet Green; and its most popular channel among female viewers, TLC.
In contrast to the currently prevailing method of estimating species distributions using expert-drawn range maps, correlative species distribution models (SDMs) can provide estimates at very fine spatial grains and largely account for widespread sample bias as well as the prevalent Wallacean shortfall in species occurrence data.
Our analysis based on widespread sampling of both nuclear and mitochondrial DNA sequences across the geographic distribution of the Amphiumidae, reveals three primary genetic lineages that correspond to the three recognized species (Figure 2).
Here we examined the species status of nearly 50% of European Rhithrogena diversity using a widespread sampling scheme of Alpine species that included 22 type localities, general mixed Yule-coalescent (GMYC) model analysis of one standard mtDNA marker and one newly developed nDNA marker, and morphological identification where possible.
A lack of widespread sampling for characterization and no on-going long term monitoring in this region prevents quantification of temporal patterns in diversity or abundance, as well as the detection of changes in these metrics by natural or anthropogenic disturbances.
However, more widespread sampling of Africa is required to verify this.
In an outbreak setting, widespread sampling, including sampling of sites that served as likely exposures for cases, is an important step in identifying possible sources of transmission.
Widespread sampling in this study has shown that corals thought to belong to the same species across the central Indo-Pacific are actually from distinct lineages.
There is an explicit assumption in population genetic studies that more widespread sampling will reveal more ancient demographic patterns, and thus local sampling will reveal only the most recent demographic events.
A more definitive conclusion on the significance of the variation in genome size and GC content among these bacteria will only be possible with more widespread sampling of taxa in the family.
