Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...
From my personal experiences, I’ve noticed that Latinx students and families are most receptive to college-related information communicated as anecdotes. Latinx students are among the most poorly represented demographic at universities nationwide, which I believe can be mitigated through calculated efforts to increase collegiate literacy and understanding. This project is...

The marine climate of the Galapagos is spatially and seasonally

Local property-owning residents maintain high levels of interest

Factors, however, such as proximity, personal interests, use patterns

Therefore, a relatively stable water source from either deeper soil profiles or ground water is necessary...

Only two genome-wide significant loci associated with longevity have been identified so far, probably because of insufficient sample sizes of centenarians, whose genomes may harbor genetic variants associated with health and longevity. Here we report a genome-wide association study (GWAS) of Han Chinese with a sample size 2.7 times the...

Mantel-based tests have been the primary analytical methods for understanding how landscape features influence observed spatial genetic structure. Simulation studies examining Mantel-based approaches have highlighted major challenges associated with the use of such tests and fueled debate on when the Mantel test is appropriate for landscape genetics studies.

Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...

Academic success is a salient domain of youth development and is related to positive lifelong outcomes among youth in foster care. However, youth in foster care experience compounding adversities, including maltreatment and foster care placement itself, which put them at risk of academic disengagement and underachievement. Despite these adversities, academic...
During the first full school year of the Covid-19 pandemic, two central contexts for adolescent development—home and school—changed utterly. In Oregon, most middle- and high schoolers attended school entirely remotely from the beginning of the pandemic, in March, 2020, through the end of April, 2021, removing both the supports available...
Commercial fishing is a culturally and economically significant industry on the Oregon coast. The importance of this industry to human communities is often neglected in fisheries research, with economic and ecological data being favored by managers and decision makers. Recent observations in many coastal communities have indicated aging of fishermen...

These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the...

This report is one of a series issued in cooperation with Air Force-Navy-Civil Subcommittee on Aircraft Design Criteria under the supervision of the Aircraft Committee of the Munitions Board. Information reviewed and reaffirmed November 1954 and June 1959. Date of original report October 21, 1946.
In 2008, the “Great Recession” gained its momentum and quickly grew into a global crisis that led to massive gross domestic product declines and job losses in countries around the world. Relative to prior economic downturns, young adults were greatly affected by the Great Recession. This likely placed a premium...
Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood.

Severely delinquent adolescent girls (n = 166) participated in a treatment trial and repeated

Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L.
