Growth but Not Corticosterone, Oxidative Stress, or Telomere Length Is Negatively Affected by Microplastic Exposure in a Filter‐Feeding Amphibian

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Microplastics (MPs) are of increasing global concern for species inhabiting aquatic habitats. However, the mechanisms behind animal responses to MPs still require comprehensive exploration. Amphibians are the most threatened vertebrate group with most species having a complex life cycle, commonly with an aquatic larval stage.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,

Mixed evidence for disturbance‐mediated apparent competition for declining caribou in western British Columbia, Canada

open access: yesThe Journal of Wildlife Management, EarlyView.
Investigating the decline of a caribou population in central British Columbia, we found that 1) recent wildfires were a stronger draw for primary ungulate prey than cutblocks, 2) most predators were associated with primary prey but had mixed responses to disturbance, and 3) caribou used cutblocks, potentially increasing their risk.
