| using bioacoustics to examine shifts in songbird phenology. | monitoring patterns in biodiversity and phenology have become increasingly important given accelerating levels of anthropogenic change. long-term monitoring programs have reported earlier occurrence of spring activity, reflecting species response to climate change. although tracking shifts in spring migration represents a valuable approach to monitoring community-level consequences of climate change, robust long-term observations are challenging and costly. audio recordings and metrics of bioaco ... | 2016 | 27547306 |
| redescription of monorcholepis dujardini (krabbe, 1869) and m. passerellae (webster, 1952) (cestoda: cyclophyllidea: aploparaksidae) in passerine birds from the holarctic region. | two species of avian tapeworms, monorcholepis dujardini (krabbe, 1869) and m. passerellae (webster, 1952), of the cyclophyllidean family aploparaksidae mayhew, 1925 (earlier included in the hymenolepididae) are redescribed. relative to congeners, the morphology of the strobila of both species shows strong similarities including a unique form of the cirrus. separation of these species, however, can be based on the number (40-53 and 25-31, respectively) and size (18-25 microm and 14-18 microm) of ... | 2007 | 17441439 |

| biotic factors influencing the unexpected distribution of a humboldt marten (martes caurina humboldtensis) population in a young coastal forest. | pacific martens (martes caurina) are often associated with mature forests with complex structure for denning, resting, and efficient hunting. nonetheless, a small isolated population of the humboldt subspecies of pacific martens (martes caurina humboldtensis) occupies a narrow strip of young, coastal forest (< 70 years old) but not inland mature forest in the central oregon coast range. we examined factors contributing to this unexpected distribution of martens by 1) analyzing marten diets using ... | 2019 | 31042737 |
