Fires Slow Population Declines of a Long-lived Prairie Plant through Multiple Vital Rates, Scott W. Nordstrom, Amy B. Dykstra, and Stuart Wagenius
In grasslands worldwide, modified fire cycles are accelerating herbaceous species extinctions. Fire may avert population declines by increasing survival, reproduction, or both. Survival and growth after fires may be promoted by removal of c...

Neurotensin and cholecystokinin contract gallbladder circular muscle in chickens, Teresa F. DeGolier, D. R. Brown, Gary E. Duke, M. M. Palmer, J. R. Swenson, and Robert E. Carraway
The contractile effects of neurotensin (NT) and cholecystokinin octapeptide (CCK-8) on isolated circular smooth muscle strips of chicken gallbladder were investigated. The NT (0.25-300 nM) produced concentration-dependent contractions on sm...

Release of avian neurotensin in response to intraluminal contents in the duodenum of chickens, Teresa F. DeGolier and Robert E. Carraway
Peripheral and hepatic-portal plasma levels of neurotensin (NT) in fed and fasted chickens were determined using RIA. Portal levels of NT1-13 (fed = 61.3 ± 3.9 fmol/mL; fasted = 44.5 ± 3.9 fmol/mL) were significantly higher than peripheral ...
