Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result, most marine microorganisms
have evolved systems for responding to nitrogen stress. The highly abundant alphaproteobacterium “Candidatus
Pelagibacter ubique,” a cultured member of the order Pelagibacterales (SAR11), lacks the canonical GlnB, GlnD, GlnK, and...
Research suggests that entrepreneurs tend to seek to maximize utility when considering whether to pursue a new venture opportunity. However, when choosing whether to persist with their current venture or not, utility maximization may not be of primary importance. Using a conjoint experiment, we examine the difference between policies in...
This paper shows the first autocorrelation of basketball shot results is a highly biased
and inconsistent estimator of the first autocorrelation of the ex ante probabilities the
shots are made. Shot result autocorrelation is close to zero even when shot probability
autocorrelation is close to one. The bias is caused...
Little research has investigated girls’ and college women’s reactions to non-objectified media images of women, including those that depict women in instrumental activities like playing a sport. This study examined open-ended responses to images of performance athletes, sexualized athletes, and sexualized models. Participants were 258 adolescent girls (ages 13-18) and...
Previous research has shown that pyridine growth regulator herbicides can affect seed production in annual grasses including downy brome, Japanese brome, wheat, and other cereal grain crops. Aminocyclopyrachlor is a pyridine carboxylic acid growth regulator herbicide that has recently been registered for broadleaf weed and brush control in nonagricultural areas,...
Sustaining forest resources requires a better understanding of forest ecosystem processes, and how management decisions and climate change may affect these processes in the future. While plot and inventory data provide our most detailed information on forest carbon, energy, and water cycling, applying this understanding to broader spatial and temporal...
Natal dispersal is an important driver of population and colonization dynamics, yet factors that
affect timing and distance of post-fledging movements are poorly understood. We studied post-fledging movements
of 34 (12 male and 22 female) juvenile Burrowing Owls (Athene cunicularia) between June 2002 and April
2003, in a nonmigratory population...
Objective. To examine the relationship between wealth and cardiovascular disease risk factors among Hispanic/Latinos of diverse backgrounds.
Design. This cross-sectional study used data from 4,971 Hispanic/Latinos, 18 to 74 years, who participated in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) baseline exam and the HCHS/SOL Sociocultural Ancillary Study. Three...
The Andes of south-central Chile, with the valuable and dominant timber species Nothofagus dombeyi and N. alpina, have been heavily high-graded. Restoring these high-graded forests with these species is challenging since they are light demanding and the understory becomes dominated by bamboo (Chusquea culeou), which prevents natural regeneration. In this...
