| a review of the mite subfamily harpirhynchinae (acariformes: harpirhynchidae)--parasites of new world birds (aves: neognathae). | mites of the subfamily harpirhynchinae (acariformes: cheyletoidea: harpirhynchidae) associated with neognathous birds (aves: neognathae) in the new world are revised. in all, 68 species in 8 genera are recorded. among them, 27 new species and 1 new genus are described as new for science: harpyrhynchoides gallowayi bochkov, oconnor and klompen sp. nov. from columba livia (columbiformes: columbidae) from canada (manitoba), h. zenaida bochkov, oconnor and klompen sp. nov. from zenaida macroura (col ... | 2015 | 26624161 |
| nasal mites of the subfamily speleognathinae (ereynetidae) from birds in texas. | nasal mites of the subfamily speleognathinae were recovered from several species of birds in texas. new host records include ophthalmophagus striatus (crossley) 1952 from columbigallina passerina, boydaia clarki fain 1963 from callipepla squamata, boydaia falconis fain 1956 from falco sparverius, and boydaia tyrannus ford 1959 from myiarchus cinerascens. also recovered was astrida coccyzae pence 1972 from coccyzus americanus. boydaia pheucticola sp. n. from pheucticus melanocephalus is described ... | 1976 | 932921 |
| implications of climate change for bird conservation in the southwestern u.s. under three alternative futures. | future expected changes in climate and human activity threaten many riparian habitats, particularly in the southwestern u.s. using maximum entropy (maxent3.3.3) modeling, we characterized habitat relationships and generated spatial predictions of habitat suitability for the lucy's warbler (oreothlypis luciae), the southwestern willow flycatcher (empidonax traillii extimus) and the western yellow-billed cuckoo (coccyzus americanus). our goal was to provide site- and species-specific information t ... | 2015 | 26700871 |
| irrigation and avifaunal change in coastal northwest mexico: has irrigated habit attracted threatened migratory species? | irrigation in desert ecosystems can either reduce or increase species diversity. groundwater pumping often lowers water tables and reduces natural wetlands, whereas canal irrigation often creates mesic habitat, resulting in great increases in avian diversity from irrigation. here we compare a dataset of potential natural vegetation to recent datasets from areal and satellite imagery to show that 60% of the land in the coastal plain of southern sonora and northern sinaloa lying below 200 m elevat ... | 2015 | 26312181 |
| current status of western yellow-billed cuckoo along the sacramento and feather rivers, california. | to evaluate the current status of the western population of the yellow-billed cuckoo (coccyzus americanus) along the sacramento and feather rivers in california's sacramento valley, we conducted extensive call playback surveys in 2012 and 2013. we also quantified the amount and distribution of potential habitat. our survey transects were randomly located and spatially balanced to sample representative areas of the potential habitat. we estimated that the total area of potential habitat was 8,134 ... | 2015 | 25915801 |
| effects of traffic noise on occupancy patterns of forest birds. | noise may drive changes in the composition and abundance of animals that communicate vocally. traffic produces low-frequency noise (<3 khz) that can mask acoustic signals broadcast within the same frequency range. we evaluated whether birds that sing within the frequency range of traffic noise are affected by acoustic masking (i.e., increased background noise levels at the same frequency of vocalizations reduce detection of vocalization) and are less abundant in areas where traffic noise is loud ... | 2011 | 21410531 |
| distribution-wide effects of climate on population densities of a declining migratory landbird. | 1. increases in global temperatures have created concern about effects of climatic variability on populations, and climate has been shown to affect population dynamics in an increasing number of species. testing for effects of climate on population densities across a species' distribution allows for elucidation of effects of climate that would not be apparent at smaller spatial scales. 2. using autoregressive population models, we tested for effects of the north atlantic oscillation (nao) and th ... | 2006 | 16903059 |
