| the roles of mosquito and bird communities on the prevalence of west nile virus in urban wetland and residential habitats. | this study investigated the impacts of urban wetlands and their adjacent residential environments on the transmission dynamics of west nile virus (wnv) within the state of new jersey (usa). a working hypothesis was that urban wetlands decrease the local prevalence of wnv through the dilution effect from increased bird diversity, and through relative reductions in the numbers of competent avian host and mosquito species commonly associated with wnv. surveys of mosquito and bird communities were u ... | 0 | 25484570 |
| spatial variation in host feeding patterns of culex tarsalis and the culex pipiens complex (diptera: culicidae) in california. | west nile virus (family flaviviridae, genus flavivirus, wnv) is now endemic in california across a variety of ecological regions that support a wide diversity of potential avian and mammalian host species. because different avian hosts have varying competence for wnv, determining the blood-feeding patterns of culex (diptera: culicidae) vectors is a key component in understanding the maintenance and amplification of the virus as well as tangential transmission to humans and horses. we investigate ... | 0 | 22897051 |
| host group formation decreases exposure to vector-borne disease: a field experiment in a 'hotspot' of west nile virus transmission. | animals can decrease their individual risk of predation by forming groups. the encounter-dilution hypothesis extends the potential benefits of gregariousness to biting insects and vector-borne disease by predicting that the per capita number of insect bites should decrease within larger host groups. although vector-borne diseases are common and can exert strong selective pressures on hosts, there have been few tests of the encounter-dilution effect in natural systems. we conducted an experimenta ... | 0 | 25339722 |

| flicker response contours for the sparrow, and the theory of the avian pecten. | the flicker contour for the house sparrow passer domesticus is duplex, corresponding to the presence of both rods and cones in the retina. the presence of the pecten brings about changes in the "cone" part of the contour when the light-time in the flash cycle is varied. these changes are of the same sort as those we have already described for the visually simplex zebra finch, and for man provided with an artificial "pecten shadow." the changes are such as to greatly enhance flicker acuity for sm ... | 1944 | 19873388 |

| house sparrows: rapid evolution of races in north america. | conspicuous adaptive differentiation in color and size has occurred in the house sparrow (passer domesticus) in north america and the hawaiian islands since its introduction in the middle of the 19th century. patterns of geographic variation in north america parallel those shown by native polytypic species, in conformity with gloger's and bergmann's ecogeographic rules. racial differentiation of house sparrow populations may require no more than 50 years. | 1964 | 17836354 |

| entrainment of circadian rhythms by sound in passer domesticus. | the circadian locomotor rhythm of house sparrows was entrained by a sound stimulus. the birds were maintained at a constant temperature in, dim green light. the entraining agent was 4 (1/2) 12 hours of tape-recorded bird song ,played each day. variations in the response to this stimulus have been correlated with individual variations in free-running period. this is the first clear demonstration that a biological clock can be influenced by sound stimuli. | 1966 | 5924929 |

| circadian clock in photoperiodic time measurement: a test of the bünning hypothesis. | a technique has been developed for effectively separating the direct inductive effect of a light signal from its effect on the phase of the rhythm of sensitivity to photoperiodic induction. with this technique it has been shown that a 75-minute pulse of light per day, when appropriately positioned with respect to the circadian activity cycle of the sparrow passer domesticus, is sufficient to produce a response normally produced only by long days. the results cannot be interpreted in terms of a r ... | 1967 | 6038688 |

| pineal function: the biological clock in the sparrow? | the pineal organ of the house sparrow, passer domesticus, is essential for persistence of the circadian locomotor rhythm in constant conditions. upon removal of the pineal body, activity becomes arrhythmic. however, pinealectomy does not abolish the rhythm of locomotor activity in birds exposed to light-dark cycles. pinealectomized birds are entrained by light cycles in much the same manner as are normal birds. our data demonstrate that the pineal organ is a crucial component of the endogenous t ... | 1968 | 5647435 |

| extraretinal light perception in the sparrow. 3. the eyes do not participate in photoperiodic photoreception. | photoperiodic control of testis growth in passer domesticus (house sparrow) is mediated entirely by extraretinal photoreceptors in the brain. the eyes do not participate in photoperiodically significant photoreception. removal of the pineal organ does not affect either the response to light or, to a first approximation, the process of recrudescence. the intensity of light reaching the retina and that reaching the extraretinal photoreceptor were varied independently. this technique will make it p ... | 1970 | 5272320 |

| photoperiodically significant photoreception in sparrows: is the retina involved? | blind house sparrows (150 birds) and normal ones (199 birds) were subjected to various photoperiodic treatments consisting of cycles of 12 hours light, 12 hours dark and 16 hours light, 8 hours dark at intensities ranging from 20 to 500 lux. the testicular, response of the blind birds was found to be indistinguishable from the response of normal birds under these conditions. the data show that a functional extraretinal photoreceptor exists in this species which is fully capable of mediating the ... | 1970 | 5460604 |

| thermoresponsiveness of the preoptic region of the brain in house sparrows. | heating the preoptic region of the house sparrow caused the bird to decrease its metabolism and to decrease its body temperature, whereas cooling that region caused an increase in metabolism and an increase in body temperature. these responses indicate that the preoptic region of birds, like that of other vertebrates, is an important center for thermoregulation. | 1970 | 5441023 |

| pineal function in sparrows: circadian rhythms and body temperature. | deep body temperature of the house sparrow, passer domesticus, was monitored continuously by radio telemetry. pinealectomy abolished the normal circadian rhythm of body temperature in constant darkness, and significantly altered the amplitude of body temperature rhythms entrained to light cycles. the body temperature minima of pinealectomized birds never fell as low as those of unoperated birds regardless of the light conditions; the temperature maxima of both normal and pinealectomized birds we ... | 1971 | 5119105 |
| temporal synergism of corticosterone and prolactin controlling gonadal growth in sparrows. | gonadal growth was controlled in two avian species by corticosterone and prolactin injected daily at various times. testicular growth was induced in photorefractory house sparrows (passer domesticus) kept in continuous light by prolactin injected 4 or 8 hours after administration of corticosterone. other temporal patterns were ineffective. gonadal growth was also stimulated in photosensitive white-throated sparrows (zonotrichia albicollis) kept in continuous light by prolactin injected 12 hours ... | 1971 | 5111566 |

| efficiency of energy utilization of the house sparrow, passer domesticus. | multiple regression analyses were made of the effect of food composition upon energetic efficiency and existence energy of house sparrows, passer domesticus. protein content of experimental food is the most important of eleven independent variables tested in the prediction of energetic efficiency. other variables significantly affecting energetic efficiency are fat content of food, ambient temperature, caloric content per gram of experimental food, weight change, geographic location of the captu ... | 1976 | 28308870 |
