Mobility is a key factor determining lepidopteran species responses to environmental change. However, direct multispecies comparisons of mobility are rare and empirical comparisons between butterflies and moths have not been previously conducted. Here, we compared mobility between butterflies and diurnal moths and studied species traits affecting butterfly mobility. We experimentally marked and...

Photo-identification surveys of Indo-Pacific bottlenose dolphins were conducted from 2009 to 2014 off Reunion Island (55°E33'/21°S07'), in the Indian Ocean. Robust Design models were applied to produce the most reliable estimate of population abundance and survival rate, while accounting for temporary emigration from the survey area (west coast). The sampling scheme consisted of a five-month (J...

This paper uses linked Swiss administrative and survey data to examine the relationship between educational mismatch in labour market emigration decisions, carrying out analysis for both native previous immigrant workers. In turn, migrants' decisions separate returning home from onward migration a third country. We find that undereducation is positively associated with probability of return cou...
