The influence of 3-methylcholanthrene to zebra mussel (Dreissena polymorpha) larvae was studied. The artificial spawning of zebra mussels was used for obtaining larvae. Two different concentrations of 3-methylcholanthrene were used. The chromosome analysis showed a significant increase in chromosome aberrations (CA) at the higher concentration of the compound. The resistance of zebra mussel lar...

Grevy’s zebra (Equus grevyi) populations declined dramatically in the last decades of the 20 century. Though now stabilising, there has been an estimated 50-68% drop in numbers over the past 18 years (IUCN, 2012). While there are many threats facing the species, the role of parasite burdens in this decline is poorly understood. Lewa Wildlife Conservancy provides ex situ or marginal (transition ...

The Zebra Finch (Taeniopygia guttata) is the first species of passerine bird with a complete genome sequence, making it an exciting time for avian evolutionary biology. Native to Australia and the Lesser Sunda Islands, this species has long played an important role in the study of ecology, behaviour and neuroscience. With the sequencing of its genome, the Zebra Finch now also represents an impo...

A zebra-crossing detection method for intelligent vehicle is proposed in this paper. The method is performed on a bird-eye view image called inverse perspective mapping image. The complete method includes two phrases. First, a morphological filer followed by horizontal projection is applied to fast extract candidate zebra-crossing regions, where the size and structure information of zebra-cross...

Zebra Finches (Taeniopygia guttata) are the most commonly used laboratory songbird species, yet their embryological development has been poorly characterized. Most studies to date apply Hamburger and Hamilton stages derived from chicken development; however, significant differences in development between precocial and altricial species suggest that they may not be directly comparable. We provid...

Little is known about specific host chemistry effects on zebra chip disease symptom development in potatoes (Solanum tuberosum). This research compared chemical profiles and defense-related enzyme levels between non-symptomatic and zebra chip-symptomatic potato tubers. Levels of phenolics, five amino acids, peroxidases, polyphenol oxidases, chitinases, and b-1,3-glucanases were greater in sympt...
