enemies is leaving insects away half a gram can live so long in china for far
opted to billion monarch butterflies migrate every year to winter in mexico
that's great colleges sonya all ties that goes to get a good look at
fifty one point five times
his support for the national science foundation all ties are and her team
study how long distance migration in flying animals
affects the spread of evolution of infectious disease in monarchs they
study a parasite
so at all but our fight for their really heavily infected will look like this one
this is the president harris played
although free assistance electricity ra coat the first
this flying treadmill in her lap at the university of georgia tracks bead and
stamina
on average infected monarchs
why about twenty percent less while unhealthy butterflies
we are now given diseases can spread quickly
it only takes one infected person hopping on an airplane but for insects
and birds long distance travel often means lower infection rates perhaps only
the strong survived that we had to run a marathon with the flu
probably wouldn't do very well the animals than most heavily impacted
simply drop out of this migration on route to their wintering sites and they
simply can't make a lot of sense to me
but human activities like habitat destruction and herbicide use hard
disrupting some of these long-standing migration patterns if we take them i'm
gration away
and we're left with smaller ram them populations that don't migrate can
actually see infections build up in this country masons and i could possibly
increase the risk
of pathogens jumping over into people and their domesticated animals in peru
all ties his team studies vampire facts their populations have exploded as
ranchers have introduced livestock into the andes andy anderson
and more bloodthirsty bats might mean more rabies one of the main goals we
have is to try to understand what determines the frequency and intensity
of realism breaks
part of what we do about it all ties are also analyzes data and parasites samples
sent in from citizens scientists around the world
for a ms to piece together the big picture of how pathogens spread when
