By Rudy Van der Elst

Книга характеризует более чем three hundred видов рыб, которых можно наиболее часто увидеть либо поймать в прибрежных районах Южной Африки. Каждый раздел, посвященный определенному виду, включает детальное описание, полноцветную фотографию, заметки по образу жизни, включая многие малоизвестные и интересные аспекты поведения, карты локального распространения и встречаемости в мире, наиболее современные ограничения в отношения ловли. Книга будет полезна всем, кто интересуется рыбами и рыбалкой.

Sample text

Thus, movies collected at 5 Hz, for example, would be adequate to capture diameter changes associated with sensory-evoked hemodynamic responses and vasomotion (Drew et al. 2011). Heart-beat and breathing rates do not typically result in appreciable diameter changes. A further advantage of planar scans is that conduction of dilatory or constrictive changes may be easily observed along a length of vasculature. As with line-scan data, the full-width of half maximum of a segment of 2 Cerebral Vasodynamics in Awake Mice 35 vasculature is calculated from each image using custom-written software to generate a diameter time-series from the movie.

In order to collect more samples simultaneously and with varying trajectories within the imaging plane, we use custom software to direct the imaging laser beam in a user-defined path (Figs. 5c) (Valmianski et al. 2010; Driscoll et al. 2011), following earlier work (Göbel et al. 2007; Göbel and Helmchen 2007; Lillis et al. 2008). Linear segments of constant scan speed traverse along the length of the center of the vessel and across the width of the vessel to measure RBC speed and lumen diameter, respectively (Fig.

Conventionally, single line-scans have been used to sample the RBC velocity and diameter of a vessel separately (Schaffer et al. 2006; Shih et al. 2009). However, blood flow is dynamic and could change within the time between each scan. In order to collect more samples simultaneously and with varying trajectories within the imaging plane, we use custom software to direct the imaging laser beam in a user-defined path (Figs. 5c) (Valmianski et al. 2010; Driscoll et al. 2011), following earlier work (Göbel et al.
