Despite widespread use of fecal pellet-group counts as an index of ungulate density, techniques used to convert pellet-group numbers to ungulate numbers rarely are based on counts of known individuals, seldom evaluated across spatial and temporal scales, and precision is infrequently quantified. Using DNA from fecal pellets to identify individual deer, we evaluated the relationship between pell...

Copepod fecal pellets are often degraded at high rates within the upper part of the water column. However, the identity of the degraders and the processes governing the degradation remain unresolved. To identify the pellet degraders we collected water from Øresund (Denmark) approximately every second month from July 2004 to July 2005. These water samples were divided into 5 fractions (<0.2, <2,...

A78-year-old man was hospitalized because of chest pain that had started 2 hours earlier while rifle shooting. On admission, he was alert and his vital signs were normal. Physical examination revealed no abnormalities, except for a wound at the jugular notch, presumably due to the entrance of a pellet. No exit wounds were found. The ECG showed marked ST-segment elevation in the inferior leads. ...

A small accumulation of bones from the Norian (Upper Triassic) of the Seazza Brook Valley (Carnic Prealps, Northern Italy) was originally (1989) identified as a gastric pellet made of pterosaur skeletal elements. The specimen has been reported in literature as one of the very few cases of gastric ejecta containing pterosaur bones since then. However, the detailed analysis of the bones preserved...

BACKGROUND Xylitol chewing gum has been shown to reduce Streptococcus mutans levels and decay. Two studies examined the presence and time course of salivary xylitol concentrations delivered via xylitol-containing pellet gum and compared them to other xylitol-containing products. METHODS A within-subjects design was used for both studies. Study 1, adults (N = 15) received three xylitol-contain...

Residential combustion has been identified as one of the main sources of particulate matter (PM); fine particles are important because of their adverse effects on human health and the environment. In this thesis, fine particle emissions originating from residential pellet combustion were characterized in different operational situations and using different raw materials as pellet fuel. Moreover...

Owls are important contributors to the Tertiary small-vertebrate fossil record. They concentrate small-vertebrate remains by producing pellets rich in skeletal material that provide a sample of the small-vertebrate fauna of an area. A common assumption is that different predators inflict unique fragmentation and skeletal element representation signatures, thus providing a method for identifying...
