Modelling and mapping potential hooded warbler (Wilsonia citrina) habitat using remotely sensed imagery
Modelling and mapping of hooded warbler (Wilsonia citrina) nesting habitat in forests of southern Ontario were conducted using Ikonos and Landsat data. The study began with an analysis of skyward hemispherical photography to determine canopy characteristics associated with nest sites. It showed that nest sites had significantly less overhead canopy cover and larger maximum gap size than in non-...
متن کاملBird mitochondrial gene order: insight from 3 warbler mitochondrial genomes.
Two main gene orders exist in birds: the ancestral gene order and the remnant control region (CR) 2 gene order. These gene orders differ by the presence of 1 or 2 copies of the CR, respectively. Among songbirds, Oscines were thought to follow the ancestral gene order, with the exception of the lyrebird and Phylloscopus warblers. Here, we determined the complete mitochondrial genome sequence of ...
متن کاملGnathostomosis in fish from Tres Palos Lagoon, Guerrero, Mexico.
sporadic serogroup C ET-24 strain. The 16S rRNA gene sequences of 66 N. meningitidis isolates representing serogroups A, B, C, W135, Z, and Y were diverse, with nine different sequences among the NMW135 isolates. Finally , all four recent NMW135 isolates had identical NheI pulsed-field gel electrophoresis (PFGE) patterns distinct from patterns seen in other NMW135 isolates. All these molecular ...
متن کاملFactors affecting aural detections of songbirds.
Many factors affect the number of birds detected on point count surveys of breeding songbirds. The magnitude and importance of these factors are not well understood. We used a bird song simulation system to quantify the effects of detection distance, singing rate, species differences, and observer differences on detection probabilities of birds detected by ear. We simulated 40 point counts cons...
متن کاملQuestions raised by the consumption of cane sugar by a Black-throated Blue Warbler (Setophaga caerulescens)
I address questions raised by an observation of a Black-throated Blue Warbler (Setophaga caerulescens) eating unrefined granulated cane sugar in Kingston, Jamaica. Sugar consumption implies the presence of taste receptors sensitive to sucrose and digestive sucrase activity sufficient to assimilate highly concentrated sucrose solutions. The ability to efficiently digest disaccharides, such as su...
