| life history and host specificity of mediorhynchus centurorum nickol 1969 (acanthocephala: gigantorhynchidae). | examination of 1905 arthropods from a swamp and surrounding pasture in sothern louisiana revealed larval specimens of mediorhynchus centurorum in 8 of 228 woodroaches, parcoblatta pensylvanica, but in no other species. the life cycle was confirmed by feeding eggs of m. centurorum to laboratory-reared woodroaches. cystacanths later recovered from the woodroaches developed into mature worms when pipetted into esophaguses of red-bellied woodpeckers, centurus carolinius: red-headed woodpeckers, mela ... | 1977 | 845719 |
| comparison of statistical and theoretical habitat models for conservation planning: the benefit of ensemble prediction. | selection of a modeling approach is an important step in the conservation planning process, but little guidance is available. we compared two statistical and three theoretical habitat modeling approaches representing those currently being used for avian conservation planning at landscape and regional scales: hierarchical spatial count (hsc), classification and regression tree (crt), habitat suitability index (hsi), forest structure database (fs), and habitat association database (ha). we focused ... | 2011 | 21939060 |

| effects of restoring oak savannas on bird communities and populations. | efforts to restore and maintain oak savannas in north america, with emphasis on the use of prescribed fire, have become common. little is known, however about how restoration affects animal populations, especially those of birds. i compared the breeding densities, community structure, and reproductive success of birds in oak savannas maintained by prescribed fire (12 sites) with those in closed-canopy forests (13 sites). all sampling was conducted in illinois (u.s.a.). of the 31 bird species ana ... | 2006 | 16903107 |
| relative hippocampal volume in relation to food-storing behavior in four species of woodpeckers. | previous studies have shown that those food-storing birds of the order passeriformes that remember the locations of their caches have relatively larger hippocampal complexes than do non-storing passerines. woodpeckers constitute a different avian order (piciformes), which also includes some food-storing species. we compared hippocampal volume, relative to the volume of the rest of the telencephalon, across four species of woodpeckers with disparate caching behavior. red-bellied woodpeckers (mela ... | 1997 | 9031734 |
