Background: Fire suppression in western North America increased and homogenized overstory cover in conifer forests, which likely affected understory plant communities. We sought to characterize understory plant communities and their drivers using plot-based observations from two contemporary reference sites in the Sierra Nevada, USA. These sites had long-established natural fire programs, which have resulted in restored natural fire regimes. In this study, we investigated how pyrodiversity—the diversity of fire size, severity, season, and frequency—and other environment factors influenced species composition and cover of forest understory plant communities. Results: Understory plant communities were influenced by a combination of environmental, plot-scale recent …

Background: Transcriptomic data has demonstrated utility to advance the study of physiological diversity and organisms’ responses to environmental stressors. However, a lack of genomic resources and challenges associated with collecting high-quality RNA can limit its application for many wild populations. Minimally invasive blood sampling combined with de novo transcriptomic approaches has great potential to alleviate these barriers. Here, we advance these goals for marine turtles by generating high quality de novo blood transcriptome assemblies to characterize functional diversity and compare global transcriptional profiles between tissues, species, and foraging aggregations. Results: We generated high quality blood transcriptome assemblies for hawksbill (Eretmochelys …
The Influence Of Maternal Glucocorticoids On Offspring Phenotype In High-And Low-Risk Environments, Kirsty J. Macleod, Tracy Langkilde, Cameron P. Venable, David C. Ensminger, Michael J. Sheriff

Elevated maternal glucocorticoid levels during gestation can lead to phenotypic changes in offspring via maternal effects. Although such effects have traditionally been considered maladaptive, maternally derived glucocorticoids may adaptively prepare offspring for their future environment depending upon the correlation between maternal and offspring environments. Nevertheless, relatively few studies test the effects of prenatal glucocorticoid exposure across multiple environments. We tested the potential for ecologically relevant increases in maternal glucocorticoids in the eastern fence lizard (Sceloporus undulatus) to induce adaptive phenotypic changes in offspring exposed to high or low densities of an invasive fire ant predator. Maternal treatment had limited effects …

Understanding encounters between marine predators and fisheries across national borders and outside national jurisdictions offers new perspectives on unwanted interactions to inform ocean management and predator conservation. Although seabird–fisheries overlap has been documented at many scales, remote identification of vessel encounters has lagged because vessel movement data often are lacking. Here, we reveal albatrosses–fisheries associations throughout the North Pacific Ocean. We identified commercial fishing operations using Global Fishing Watch data and algorithms to detect fishing vessels. We compiled GPS tracks of adult black-footed Phoebastria nigripes and Laysan Phoebastria immutabilis albatrosses, and juvenile short-tailed albatrosses Phoebastria albatrus. We quantified albatrosses-vessel encounters …

Cesarean delivery is the most common surgery performed in the United States, accounting for approximately 32% of all births. Emergency Cesarean deliveries are performed in the event of critical maternal or fetal distress and require effective collaboration and coordination of care by a multidisciplinary team with a high level of technical expertise. It is not well understood how the physical environment of the operating room (OR) impacts performance and how specialties work together in the space. Objective This study aimed to begin to address this gap using validated techniques in human factors to perform a participatory user-centered analysis of physical …
Parenting In Poor Health: Examining Associations Between Parental Health, Prescription Drug Use, And Child Maltreatment, Jennifer Price Wolf, Bridget Freisthler, Karla Shockley Mccarthy
Parenting In Poor Health: Examining Associations Between Parental Health, Prescription Drug Use, And Child Maltreatment, Jennifer Price Wolf, Bridget Freisthler, Karla Shockley Mccarthy
Faculty Research, Scholarly, and Creative Activity
Rationale
Child maltreatment and problematic parenting are related to negative outcomes for children. Poor parental health could be a risk factor for problematic parenting through several mechanisms: 1) inadequate emotional regulation and coping; 2) impairment of parental capacity; and, 3) impairment of the parent-child relationship.
Objective
This study examines relationships between self-rated parental health, prescription drug use, and a broad array of negative parenting outcomes.
Methods
A sample of general population parents of children aged ten and younger was recruited from 30 mid-sized cities in California (n = 681). Weighted mixed-effects negative binomial and logistic regression models were used to …
