During the 1980s the sales and use of all-terrain vehicles (ATVs) was on the rise. Many people used them for recreation, while others started using them on their ranch or farm for work-related purposes. As a result, morbidity and mortality rates also began to climb. It became apparent that the...

Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...

We used simulated magnetic displacements to test orientation preferences of
juvenile steelhead trout (Oncorhynchus mykiss) exposed to magnetic fields
existing at the northernmost and southernmost boundaries of their oceanic
range. Fish reared in natural magnetic conditions distinguished between
these two fields by orienting in opposite directions, with headings that

Here, we describe and demonstrate a geographic information systems-based lithic morphometric research (GLiMR) software approach. GLiMR accurately and rapidly handles a sequence of ArcGIS procedures to extract geometric morphometric data from 2D and 3D scan files of lithic artifacts. GLiMR generates three main types of geometric properties: shape data, topographic...
