Declines in American Kestrel (Falco sparverius) populations are widely reported, and Breeding Bird Survey (BBS) data suggest that the North population declined significantly from 1984 to 2007. Potential causes include spread of West Nile virus (WNV), increases Cooper's Hawks (Accipiter cooperii), loss suitable habitat. We examined trends numbers both migratory resident kestrel use nest boxes eight study areas Florida, Georgia, Virginia Maryland, New Jersey, Massachusetts, Pennsylvania,...

To optimise predictive models for sentinal node biopsy (SNB) positivity, relapse and survival, using clinico-pathological characteristics osteopontin gene expression in primary melanomas. A comparison of the SNB positive negative cases was carried out 561 melanoma patients. In 199 patients, formalin-fixed tumours studied Illumina's DASL assay. cross validation approach used to test prognostic receiver operating characteristic curves were produced.

ABSTRACT Measuring survival in a declining species provides the foundation for continued research, demographic modeling, and informed conservation strategies. Although American Kestrel (Falco sparverius) populations have to decline since 1970s, little is known about their throughout full annual cycle, making it difficult identify factors responsible these declines. We used radio telemetry provide first known-fate estimates of adult kestrel survival, we present data across breeding stages,...

Abstract I observed the establishment of 240 winter territories by American Kestrels (Falco sparverius) on a 293-km census route in south-central Florida during autumn 1985. Most females arrived before males. Analysis banding records revealed that immatures both sexes and adult preceded males migration eastern North America; thus, sex ratio early arrivals was skewed toward females. In south territorial kestrels occupied habitats decreasing order foraging quality, as measured percentage cover...

Twenty‐one captive leopards (Panthera pardus kotiya) at the National Zoological Gardens in Sri Lanka were individually identified using spot pattern variation, Based on an identification method established for lions ( Panthera leo ), a code was devised examining 23 variable characters, each of which had one to three values. These characters ranged from number and spacing muzzle spots forehead eye patterns. Correlation among be used minimized principal component cluster analysis. The most...

We conducted a nest-box study from 1989–93 in north-central Florida, an effort to increase the population of threatened Southeastern American Kestrel (Falco sparverius paulus) and evaluate effect providing artificial nest sites on local population. A total 388 boxes were erected experimental area. Over 75% these placed >250 m away roadside transects we established. This enabled us measure changes density without potential bias associated with concentration kestrels at specific sites. Annual...

Demographic differences between stable and declining populations can lend insight into drivers of population decline. The American Kestrel Falco sparverius is a widespread often‐studied falcon, yet its demography poorly understood, the causes observed declines across much North America remain unknown. Using integrated models sensitivity analysis, we examine how vital rates drive growth in levels Kestrels at four discrete study sites – Florida, Idaho Pennsylvania with nestbox occupancy, New...

Previous studies have examined vegetative cover and land use immediately surrounding American Kestrel (Falco sparverius) nest sites. However, the relationship of landscape-level habitat structure to nest-site selection has received little attention. Between 1995 2007, we erected boxes in pastures meadows northwestern New Jersey. The number breeding pairs ranged from 2 59 2002. We used a Geographic Information System model habitats by kestrels (open areas dominated herbaceous vegetation)...
