Biofluid proteomics is a sensitive and high throughput technique that provides vast amounts of molecular data for biomarker discovery. More recently, dried blood spots (DBS) have gained traction as a stable, noninvasive, and relatively cheap source of proteomic data for biomarker identification in disease and injury. Snake envenomation is responsible for significant morbidity and mortality worldwide; however, much remains unknown about the systemic molecular response to envenomation and acquiring biological samples for analysis is a major hurdle.

Article Synopsis
  • - The study examines the challenges of defining species, particularly in a group of Central American toads, where factors like similar physical traits and genetic inconsistencies complicate taxonomy.
  • - By analyzing mitochondrial sequences, nuclear SNPs, morphology, and environmental data, researchers propose that a taxonomy with three distinct species is the most accurate for this complex.
  • - The research underscores the importance of clear species definitions for effective conservation efforts, given the potential misidentifications that could impact management strategies.

Brain size, brain architecture, and eye size vary extensively in vertebrates. However, the extent to which the evolution of these components is intricately connected remains unclear. Trinidadian killifish, , are found in sites that differ in the presence and absence of large predatory fish.

Article Synopsis
  • The link between bright sexual colors and mate preference dates back to Darwin, but understanding the mechanisms behind this preference took many years to develop.
  • Bright colors in male animals, while seemingly risky because they can attract predators, can actually signal their survival skills and overall fitness to potential mates.
  • Research on male Florida scrub lizards shows that their bright colors relate to infection resistance, body size, and habitat type, suggesting these colors can be trusted indicators of individual quality in different environments.

Vertebrates exhibit extensive variation in brain size. The long-standing assumption is that this variation is driven by ecologically mediated selection. Recent work has shown that an increase in predator-induced mortality is associated with evolved increases and decreases in brain size.
