A Snakemake Toolkit for the Batch Assembly, Annotation and Phylogenetic Analysis of Mitochondrial Genomes and Ribosomal Genes From Genome Skims of Museum Collections. [PDF]
ABSTRACT Low coverage ‘genome‐skims’ are often used to assemble organelle genomes and ribosomal gene sequences for cost‐effective phylogenetic and barcoding studies. Natural history collections hold invaluable biological information, yet poor preservation resulting in degraded DNA often hinders polymerase chain reaction‐based analyses.

A review of migratory Alosidae marine ecology in the northwest Atlantic. [PDF]
Abstract Migratory animals play a crucial role in connecting distinct habitats by transferring matter and energy across ecosystem boundaries. In the North Atlantic, anadromous species exemplify this through their movement between freshwater and marine environments.

Host Disease Tolerance Predicts Transmission Probability for a Songbird Pathogen. [PDF]
The effects of host disease tolerance on pathogen transmission are not well understood. Here, we use wild‐caught house finches to show that natural variation in tissue‐specific tolerance to a bacterial pathogen affects the transmission of this pathogen.

Changing perspectives: The development of preservice teachers' field-specific ability beliefs across academic disciplines. [PDF]
Abstract Background Field‐specific ability beliefs (FABs) reflect the perception that success in academic fields depends on innate, unteachable abilities. These beliefs affect teaching practices and student motivation. However, little is known about their longitudinal development during teacher education. Aims This study examines how FABs evolve during

We study the nonlinear nonhomogeneous n-point generalized Sturm-Liouville fourth-order p-Laplacian boundary value problem by using Leray-Schauder nonlinear alternative and Leggett-Williams fixed-point theorem.

Generalization for Amann's and Leggett–Williams' three-solution theorems and applications
Let \(X\) be a nonempty closed convex subset of a real ordered Banach space \(E\) and \(A:X \to X\) a completely continuous operator. The authors give conditions for \(A\) to have at least three fixed points. The results generalize those of \textit{H. Amann} [J. Funct. Anal. 11, 346--384 (1972; Zbl 0244.47046)], \textit{R. W. Leggett} and \textit{L. R.
