UNLIKELY CANDIDATE. "The extent of the annual journey undertaken by the Painted Lady butterfly is astonishing. This tiny creature weighing less than a gram with a brain the size of a pin head and no opportunity to learn from older, experienced individuals, undertakes an epic intercontinental migration in order to find plants for its caterpillars to eat." https://lnkd.in/dbZX3Du View in LinkedIn

VANESSA CARDIU. "The whole journey is not undertaken by individual butterflies but is a series of steps by up to six successive generations so Painted Ladies returning to Africa in the autumn are several generations removed from their ancestors who left Africa earlier in the year." Six successive generations to complete this migration in one summer, leapfrogging generationally over space and time. https://lnkd.in/dbZX3Du View in LinkedIn

HALF OF ALL BIRDS MIGRATE. "Each year roughly 50 billion birds, involving about half of all avian species, perform some type of migratory movement." (8 times the global human population annually migrates). https://lnkd.in/dapscwg View in LinkedIn

MOLECULAR BASIS OF MIGRATION. "The lack of knowledge of the molecular basis of migration is currently not only limiting our insight into the proximate control of migration, but also into its evolution." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

CAUSE OR EFFECT? "Despite extensive research over decades, the molecular, physiological and endocrinological mechanisms underlying the regulation of migratory movements remain largely unknown. In particular, it remains unclear whether endocrine changes are a cause or an effect of migratory processes." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

FROM GENE TO PHENOTYPE. "There is a clear need to study the molecular genetic basis of migration, which may bridge the gap between genes and phenotype." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

ENDOGENOUS GPS. "The amazing accuracy of migratory orientation performance across the animal kingdom is facilitated by the use of magnetic and celestial compass systems that provide individuals with both directional and positional information that provide individuals with both directional and positional information." https://lnkd.in/dWFycUQ View in LinkedIn

GENES CONTROLLING ORIENTATION. "Quantitative genetics analyses in several animal systems suggests that migratory orientation has a strong genetic component. Nevertheless, the exact identity of genes controlling orientation remains largely unknown." https://lnkd.in/dWFycUQ View in LinkedIn

BODILY AND BEHAVIORAL CHANGES. "Before and during migration, migratory birds undergo a profound and synchronized shift in a set of physiological adaptations and behavioural traits." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn

PHYSIOLOGICAL PREPAREDNESS. "Migratory disposition, i.e. a state of readiness for prolonged flights, comprises hypertrophy of flight muscles, fat deposition in the adipose tissue, integrated changes in enzyme activities involved in the energy metabolism, hyperphagia, dietary changes and the development of migratory activity." http://rspb.royalsocietypublishing.org/content/early/2011/02/11/rspb.2010.2567 View in LinkedIn
