In this paper we present a time-stratigraphic scheme and geologic time scale for the protoplanet Vesta, based on global geologic mapping and other analyses of NASA Dawn spacecraft data, complemented by insights gained from laboratory studies of howardite–eucrite–diogenite (HED) meteorites and geophysical modeling. On the basis of prominent impact structures and their associated deposits, we pro...

This research is the first published study to report a relationship between climate variables and plastron growth increments of turtles, in this case the endangered Nova Scotia Blanding's turtle (Emydoidea blandingii). We used techniques and software common to the discipline of dendrochronology to successfully cross-date our growth increment data series, to detrend and average our series of 80 ...

The chronology of the southeast Italian Neolithic may appear a rather over-worked subject, since there are several relatively recent treatments of various aspects (Alexander 2005; Skeates 2000; 2003), as well as a range of earlier articles (Pluciennik 1994; 1997; Sargent 1985; Skeates 1994; Whitehouse 1994: 86–90). It therefore may seem not to need additional attention now. Nonetheless, ‘rethin...

north-western iran comprises diverse geographical landscapes, including pastures of piedmonts, mountains, and well-watered plains. the present chronology of this region, nevertheless, is based exclusively on data collected from sites around the urmia lake, other regions being almost totally ignored. during the late bronze age (hereafter lba) a new way of life took shape in the mountainous regio...

BACKGROUND The purpose of this study was to investigate whether there is a bi-directional relationship between sleep characteristics (time in bed, sleep duration, sleep chronology, and sleep efficiency) and time spent participating in outdoor active play among children. METHODS Participants consisted of 433 children aged 10-13 years from Kingston, ON, Canada. Time in bed, sleep duration, slee...

Tree-ring data from Chamaecyparis lawsoniana (A. Murr.) Parl. (Port Orford cedar; Cupressaceae) were used to create a standardized chronology, assess the local, limiting factors on radial growth, and investigate the extent of a unique climatic event. We produced a 580-year tree-ring chronology (A.D. 1420 to 2000) from a large number of cedars (n 5 1537) sampled in one 37 km2 area in the Siskiyo...

Understanding the geographic range and growth of species is essential for effective land management in a landscape affected by anthropogenic activity and climate change. Climate change is expected to alter the distribution and growth of many tree species in eastern North America, including northern white cedar (Thuja occidentalis L.). This research examined the effects of climate on radial grow...
