Meadow pipit ( Anthus pratensis ) egg appearance in cuckoo ( Cuculus canorus ) sympatric and allopatric populations
Host populations tend to show less ability to discriminate against parasites when living in their absence. However, comparison of rejection rates among sympatric and allopatric host populations does not allow determination of whether the greater tolerance in allopatric populations reflects a genetic change or phenotypic plasticity. Here we test the existence of changes in a host’s adaptation to...
متن کاملHybridization and apparent hybridization between meadow pipit (Anthus pratensis) and water pipit (A. spinoletta).
Occasionally, even a single breeding event may provide significant biological information, of which the present report of a pairing between a female meadow pipit (Anthus pratensis) and a male water pipit (A. spinoletta) may be a good example. Events of mixed-species pairing appear to be relatively common in birds (ARNOLD 1997). However, only rarely has researchers investigated whether such pair...
متن کاملIdentification of Sprague's Pipit Nest Predators
Nest predation is the primary factor influencing grassland songbird reproductive success. Understanding factors driving spatial and temporal variation in nest survival requires that we identify the primary nest predators and factors influencing predator abundance and behavior. Predation events are rarely witnessed, and the identification of nest predators is inferred, often incorrectly, from ne...
متن کاملPipit: visualizing functional impacts of structural variations
SUMMARY Pipit is a gene-centric interactive visualization tool designed to study structural genomic variations. Through focusing on individual genes as the functional unit, researchers are able to study and generate hypotheses on the biological impact of different structural variations, for instance, the deletion of dosage-sensitive genes or the formation of fusion genes. Pipit is a cross-platf...
متن کاملCuckoo Hashing
We present a simple and e cient dictionary with worst case constant lookup time, equaling the theoretical performance of the classic dynamic perfect hashing scheme of Dietzfelbinger et al. (Dynamic perfect hashing: Upper and lower bounds. SIAM J. Comput., 23(4):738 761, 1994). The space usage is similar to that of binary search trees, i.e., three words per key on average. The practicality of th...
