Morphology of migration: associations between wing shape, bill morphology and migration in kingbirds (Tyrannus)
(Oxford Univ Press, 2021-10-21)
Morphology is closely linked to locomotion and diet in animals. In animals that undertake long-distance migrations, limb morphology is under selection to maximize mobility and minimize energy expenditure. Migratory behaviours ...
East with the Night: Longitudinal Migration of the Orinoco Goose (Neochen jubata) between Manú National Park, Peru and the Llanos de Moxos, Bolivia
(Public Library of Science, 2012)
We report on the intra-Amazonian migration of a pair of Orinoco Geese (Neochen jubata) from Manú National Park, Peru. The species is Critically Endangered in Peru, so a major aim of the study was to aid conservation planning ...
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)
Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ...
Quantitative aspects of the migration and evolutive asynchronism of Schistosoma mansoni in mice
(1978-12-01)
Two groups of white mice (Mus musculus) were infected with 65 and 440 cercariae transcutaneously. Migration of Schistosoma mansoni from skin to the lungs and to the portal system thereafter was studied through fitting ...

Migration quantified: Constructing models and linking them with data
(Oxford University Press, 2011)
This chapter discusses how models, combined with modern data sources and statistical methods, can be used to test different hypotheses about the causes of migration. It presents mathematical formulations for migration and ...
