Population dynamics of killer whales (Orcinus orca) in the Crozet Archipelago, southern Indian Ocean: a mark-recapture study from 1977 to 2002 / Éric Poncelet, Christophe Barbraud, Christophe Guinet.
Title: | Population dynamics of killer whales (Orcinus orca) in the Crozet Archipelago, southern Indian Ocean: a mark-recapture study from 1977 to 2002 / Éric Poncelet, Christophe Barbraud, Christophe Guinet. |
Author(s): | Poncelet, Éric. Barbraud, Christophe. Guinet, Christophe. |

In: | Journal of Cetacean Research and Management. (2010.), Vol. 11(1) (2010) |
Abstract: | Estimates population size and annual survival probabilities for killer whales in inshore waters of Possession Island, Iles Crozet. Results indicate low survival probability estimates, decreasing from 0.935 to 0.895 for males and from 0.942 to 0.901 for females over period 1977-2002. Status of population gives cause for concern, as constant survival probability is estimated at 0.89 and constant rate of increase is estimated at 0.94 for period 1987-2000. Killer whales around Ile de la Possession appear to be in sharp decline, possibly due to low prey stocks and lethal interactions with fisheries. |
