Calibrating single-ended fiber-optic Raman spectra distributed temperature sensing data.
(Sensors (Basel), 2011)
Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are considered ...
Fatty acid composition of wild anthropoid primate milks.
(Comp Biochem Physiol B Biochem Mol Biol, 2008-01)
Fatty acids in milk reflect the interplay between species-specific physiological mechanisms and maternal diet. Anthropoid primates (apes, Old and New World monkeys) vary in patterns of growth and development and dietary ...

Dust accumulation in the canopy: a potential cause of dental microwear in primates.
(Am J Phys Anthropol, 1995-06)
Dental microwear researchers consider exogenous grit or dust to be an important cause of microscopic wear on primate teeth. No study to date has examined the accumulation of such abrasives on foods eaten by primates in the ...
Stable isotope ratios indicate diet and habitat use in New World monkeys.
(Am J Phys Anthropol, 1997-05)
This paper demonstrates the use of stable isotope ratios of carbon and nitrogen in animal tissue for indicating aspects of species behavioral strategy. We analyzed hair from individuals representing four species of New World ...
Natal emigration by both sexes in the La Pacifica population of mantled howlers: when do some stay?
(Am J Primatol, 2008-02)
We have reported previously that all male and female mantled howlers emigrate from natal groups at Hacienda La Pacifica, Costa Rica. In the years since that report, a small number of juveniles have stayed in the natal group ...
Spider monkey home ranges: A comparison of radio telemetry and direct observation
(American Journal of Primatology, 1988-01-01)
The ranging patterns of two male and five female spider monkeys (Ateles geoffroyi) were studied with the use of radio telemetry in Santa Rosa National Park, Costa Rica. The average size of a spider monkey home range was ...
Plasma lipoproteins of free-ranging howling monkeys (Alouatta palliata).
(Comp Biochem Physiol B, 1987)
1. Plasma lipids and lipoproteins of free-ranging howling monkeys from Costa Rica (Alouatta palliata), aged 5 months to 23 years, were characterized. 2. High density lipoproteins were lipid-rich, similar to HDL2 of human ...
Dust in the wind: How climate variables and volcanic dust affect rates of tooth wear in Central American howling monkeys.
(Am J Phys Anthropol, 2016-02)
OBJECTIVES: Two factors have been considered important contributors to tooth wear: dietary abrasives in plant foods themselves and mineral particles adhering to ingested food. Each factor limits the functional life of teeth. ...
