| identifying predators clarifies predictors of nest success in a temperate passerine. | 1. nest predation negatively affects most avian populations. studies of nest predation usually group all nest failures when attempting to determine temporal and parental activities, habitat or landscape predictors of success. often these studies find few significant predictors and interpret patterns as essentially random. 2. relatively little is known about the importance of individual predator species or groups on observed patterns of nest success, and how the ecology of these predators may inf ... | 2010 | 19656236 |
| the chewing lice (insecta, phthiraptera) fauna of the swainson's warbler, limnothlypis swainsonii (aves, parulidae). | we examined swainson's warblers (limnothlypis swainsonii (audubon, 1834), aves: parulidae) for lice fauna during 2 yr at three study sites in arkansas, usa. a total of 66 individuals were examined; eight birds (10.6%) were parasitized with 16 lice of two new species belonging to two genera myrsidea waterson, 1915 (amblycera: menoponidae) and brueelia kéler, 1936 (ischnocera: philopteridae). parasitological parameter data are given on the prevalence of lice on swainson's warblers. species descrip ... | 2015 | 26336250 |
| does flooding effect the apparent survival and body condition of a ground foraging migrant passerine? | natural disturbances play a fundamental role in maintaining habitat and landscape heterogeneity; however, these events can also have negative effects on some species. while we know that disturbances can reduce habitat quality for many species, leading to diminished populations and altered community structure, the effect of these events on individuals that continue to occupy affected areas remains unknown. we focused on understanding the impact of flood-mediated reduction of habitat quality on sw ... | 2017 | 28394910 |
