| ticks (ixodidae) on migrating birds in egypt, spring and fall 1962. | over a number of years studies have been carried out in egypt on the transport by migrating birds of ticks that may transmit pathogens of man and animals. in continuation of these investigations 11 036 birds migrating southwards through egypt were examined for ticks during the fall of 1962. the 881 infested birds (comprising 24 species and sub-species represented by 10 612 individuals) yielded 1442 ticks. tick-host relationships were similar to those of previous years except that in 1962 the pre ... | 1964 | 14163959 |
| vulnerability of subarctic and arctic breeding birds. | recent research predicts that future climate change will result in substantial biodiversity loss associated with loss of habitat for species. however, the magnitude of the anticipated biodiversity impacts are less well known. studies of species vulnerability to climate change through species distribution models are often limited to assessing the extent of species' exposure to the consequences of climate change to their local environment, neglecting species sensitivity to global change. the likel ... | 2017 | 28052503 |
| aploparaksis borealis sp. n. (cestoda: hymenolepididae) from passeriform and charadriiform birds in chukotka and alaska. | aploparaksis borealis sp. n. (cestoda: hymenolepididae), from the long-tailed jaeger, stercorarisu longicaudus vieillot, on the seward peninsula, alaska, and from the red-throated pipit, anthus cervinus (pallas), and the lapland longspur, calcarius lapponicus (linnaeus), in chukotka, northestern siberia, is described. this cestode is distinguished by the structure of the cirrus and other morphologic characters from other species of aploparaksis clerc 1903 in which there are 10 rostellar hooks an ... | 1977 | 845746 |
| [patterns of bird nocturnal migration at shenyang taoxian international airport, northeast china]. | the high frequency of bird strikes at night during the migration season is a remarkable characteristic of bird strikes at airports. understanding the nocturnal migration patterns of birds is important for improving the methods to prevent bird strikes at night. in this study, we combined the methods of mist-net capture and sound recording to examine the composition of bird species and the patterns of nocturnal migration at taoxian airport. we found that 56 species of birds (88.9% of the total) mi ... | 2019 | 30907552 |
