… Individual batch reactors were created by transferring 50 g wet mass of the desired manure
slurry into 120 mL clear glass vials (Wheaton Science Products, Millville, NJ) that were …

Despite the increasing feasibility of sequencing whole genomes from diverse taxa, a persistent
problem in phylogenomics is the selection of appropriate genetic markers or loci for a …

Within the New World nine-primaried oscine assemblage, feeding morphology and behavior
have long been used as a guideline for assigning membership to subgroups. For example, …

Fieldwork is considered central to an education as a physical geographer. However, there
are doubts whether all students benefit from it equally. A preferred way of learning may have …

Artificial neural networks (ANNs) have recently attracted the attention of applied geographers.
They can be employed to examine relationships in complex non-linear datasets in the …

The Hairy Woodpecker (Picoides villosus) has one of the broadest breeding distributions of
any North American bird and is also one of the most morphologically variable with as many …

Since the late 1990s, molecular techniques have fuelled debate about the role of Pleistocene

… For each of these partitions, we also plotted the relative proportions of each nucleotide for
each taxon used (eg, C vs T and A vs G). Outliers in such plots likely indicate taxa that are …

Pine and oak woodlands are common North American floral communities with distinct regional
species composition. The white‐breasted nuthatch (Aves: Sitta carolinensis) is a common …

Incomplete or geographically biased sampling poses significant problems for research in
