Abstract Of all the major pools of terrestrial carbon (C), the dynamics of coarse woody debris (CWD) are the least understood. In contrast to soils and living vegetation, the study of CWD has rarely relied on ex situ methods for elaborating controls

Tree seedling survival rates are low in the dry, harsh climate of the Bolivian altiplano. We tested two species, Polylepsis tarapacana and Cupressus macrocarpa, using four microcatchment planting methods and a control to determine if species survival

Geologic mapping, together with 73 new K-Ar and 40Ar/39Ar age determinations of 45 samples from 17 different volcanic units, plus paleomagnetic orientations, geochemical compositions, and terrestrial photogrammetry are used to define the chronostrati

Slates of the Taconic Allochthon have ellipsoidal reduction spots which have been used to determine the finite state of strain at seven sites. The strain is highly heterogeneous at all scales, ranging from several centimeters to many kilometers. Vari

The transitional behavior exhibited by Earth9s magnetic field during polarity reversals holds the key to understanding the complexities of the field. Interpretation of the severely limited reversal data set, however, remains controversial. Discussion

Because meconium diffuses into placental and umbilical cord tissue, its bioactive components are potentially capable of entering the fetal circulation. Meconium diluted in Krebs solution produces vasocontraction in human umbilical vein segments that

Hereditary multiple exostoses usually involve the long bones, but occasionally the spine. When the spine is involved, serious neurologic deficits may occur. We report a case of a 12-year-old girl with an exostosis in the cervical spine (C5), which ca
