Developmental and Behavioral Effects of Arsenobetaine in Zebrafish (Danio rerio)

Journal of Applied Toxicology, EarlyView.
ABSTRACT Arsenobetaine (AsB) is a prevalent organoarsenical in aquatic environments and is generally regarded as nontoxic. Despite its widespread occurrence, the developmental and neurobehavioral toxicity of AsB has not been systematically investigated.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Seawater carbonate chemistry and hatching success of anemonefish

, 2020
Oceans have continuously absorbed anthropogenic carbon dioxide from the atmosphere. The early life stages are likely vulnerable to low pH conditions. The present study aimed to assess the anemonefish (Amphiprionsebae), egg hatch rate and gonadal tissue ...

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Embryonic Development in Two High‐Elevation Oviparous Lizard Species: Contrasting Strategies for Coping With Cold Climates

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Understanding how species respond to local climates is crucial for predicting their responses to climate change. The cold climate of high elevations constitutes a physiological challenge for reptiles, especially during the embryonic stages of oviparous species, because embryos have limited ability to thermoregulate behaviorally. To examine how

Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

Wildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...
