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)...
BACKGROUND: School-based social-emotional and character development (SECD) programs can influence not only SECD, but also academic-related outcomes. The purpose of this study was to evaluate the impact of one SECD program, Positive Action (PA), on educational outcomes among low-income, urban youth.
METHODS: The longitudinal study used a matched-pair, cluster-randomized controlled...
Pear ester is a characteristic pear flavor attractive to codling moth (i.e., a kairomone). Traps baited with a pear ester lure can be used to monitor male and female adult codling moth activity. Pear ester is a natural volatile produced by ripening pears. Male and female codling moths have specialized...
Studies were conducted to assess glacial acetic acid (GAA) with various host plant volatiles (HPVs) and the sex pheromone, (E,E)-8, 10-dodecadien-1-ol, of codling moth, Cydia pomonella (L), as lures in traps for tortricid pests that often co-occur in tree fruits in the western United States. In addition to codling moth,...
It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...
