Population dynamics of sperm whales ( Physeter macrocephalus ) in Guadeloupe, French Caribbean: A mark‐recapture study from 2001 to 2013
International audience Sperm whales are present along the Caribbean islands in family groups of mature females, juveniles, and newborns. Their abundance and demographic rates remain poorly known. Using photo-identification data, we estimated the abundance and annual survival of sperm whales in Guade...
