For example, scientists have documented hybrid zones
between introduced and native species, and climate change has already been linked to
hybridization among flying squirrels in eastern North America.
A new study from The Condor: Ornithological Applications investigates
hybridization between Mallards and Mottled Ducks, a species specially adapted
for life in Gulf Coast marshes, and finds that while
hybridization rates are currently low, human activity could cause them to rise in the future.
This allowed the group led by Ole Seehausen (head of the Fish Ecology and Evolution department at Eawag and Professor of Aquatic Ecology at Bern University) to provide strong evidence
for his theory that
hybridization between divergent species, in conjunction with ecological opportunity, can facilitate rapid adaptive radiation.
In a study published in Nature Communications, they demonstrate
for the first time that this rapid evolution was facilitated by earlier
hybridization between two distantly related cichlid species from the Upper Nile and Congo drainage systems.
Statistical analyses of the number of Acks signals detected in in situ
hybridization experiments using sections corresponding to the middle brain parts (n = 5, 5, and 4
for 0, 30, and 60 min, respectively) revealed that there was a significant increase in the number of Acks signals at 30 and 60 min after the bee ball formation in both the Class I and the Class II KCs, and at 60 min after the bee ball formation in the brain area
between the DLs and the OLs, and in the OLs (Figure 4S).
