Breeding Density, Nest Sites, Clutch Size and Egg Dimensions of the Magpie (pica Pica) in Nw Croatia

Between 1997 and 1998 the breeding density, nest sites, clutch size and egg dimensions of the magpie (Pica pica) was investigated in a 7 km2 area in the Krapina river valley. We recorded a high breeding density of 4.79 pairs/km2 (during both years). The nests were situated at a height of 1–16 m above ground (mean = 6.74 m). Magpie nests were found in at least 9 species of bushes and trees. We r...

Wavelet-assisted volume ray casting.

Volume rendering is an important technique for computational biology. In this paper we propose a new wavelet-assisted volume ray casting algorithm. The main idea is to use the wavelet coefficients for detecting the local frequency, and decide the appropriate sampling rate along the ray according to the maximum frequency. Our algorithm is to first apply the 3D discrete wavelet transform on the v...

Effect of endurance training on cardiac morphology in Alaskan sled dogs.

The cardiac morphology of 77 conscious Alaskan sled dogs before and after 5 mo of endurance training (20 km/day team pulling a sled and musher) was studied using two-dimensional and M-mode echocardiography. Subgroups included dogs with at least one season of previous training ("veterans") and dogs undergoing their first season of training ("rookies"). Training resulted in a significant (P < 0.0...

Breeding Characteristics of the Barn Swallow (hirundo Rustica) in Nw Croatia

Dolenec, Z.: Breeding characteristics of the barn swallow (Hirundo rustica) in NW Croatia. Nat. Croat., Vol. 11, No. 4., 439–445, 2002, Zagreb. The research was carried out in the village of Mokrice (46°00'N, 15°55'E) in NW Croatia during 1998–1999. Egg length averaged 19.16 mm, egg breadth 13.72 mm, egg volume 1840.8 mm3, egg shape index 1.40 and egg weight 1.81 g (during both years). The nest...
