. Zootaxa, 3702(2), 135–149.
Abstract: In the Southern Hemisphere the species attributed to Corella eumyota , Traustedt, 1882 are likely more varied than previously expected. This ascidian species was described from specimens collected at Valparaiso (Chile). Until now it was considered as a widely distributed species in the southern hemisphere. New collections from Chile and the Antarctic area have allowed to separate two species and re-establish Corella antarctica Sluiter, 1905 as a valid species (Alurralde 2013).A morphological re-examination of many specimens from the MNHN collections and especially recent surveys as CEAMARC and REVOLTA confirms that Antarctic specimens from the Antarctic Peninsula and Terre Adélie obviously differ from sub-Antarctic material more varied than previously estimated. On the other hand, C. eumyota invasive in Europe (Lambert 2004) has been shown to be the same as specimens from Chile, New Zealand and other sub-Antarctic regions. The present morphological study compares Corella from different regions and describes a new species Corella brewinae n. sp that is found living mixed with C. eumyota populations.

Vicente C. and Monniot F. (2014). The ascidian-associated mysid Corellamysis eltanina gen.nov., sp.nov. (Mysida, Mysidae, Heteromysinae): a new symbiotic relationship from the Southern Ocean. Zootaxa, 3780(2), 323–346.
Abstract: A new mysid species representing a new genus is described based on specimens collected in the 1968 cruise of the U.S. Navy Ship Eltanin from the Macquarie Island region (Southern Ocean). The new mysid, Corellamysis eltanina, is characterized by the globular eyes lacking definite eyestalks, the seven and eighth thoracic endopods specialized as gnathopods forming a strong subchela, and by the armature and shape of the uropod endopod and telson. Corellamysis eltanina lives only in the branchial sacs of the ascidian Corella brewinae suggesting an obligate endocommensal symbiotic association. Therefore, this is the first known report of a mysid living symbiotically with a benthic tunicate, as well as the first report of a mysid symbiosis from the Southern Ocean. The distribution and habitats of known symbiont mysids are reviewed. An update of identification key to world genera and subgenera of Heteromysinae is suggested.

. Wilson J Ornithol, 153(2), 375–383-.
Abstract: Satellite transmitters and other tracking devices are valuable tools for furthering our understanding of bird movements, and their use has been steadily increasing. Since the necessary handling of birds to deploy transmitters can have deleterious consequences and the transmitter itself can add substantial mass, particularly to small species, or bring discomfort to the individual birds to which they are attached, it is important to quantify the effect such devices on both the behavior and the fitness of equipped animals. Very few studies have focused on the demographic effects of equipping birds with a satellite transmitter, with the vast majority of such studies focusing on short-term behavioral effects. We have assessed the demographic effects of attaching a satellite transmitter to the back of adult breeding Wandering Albatross individuals using long-term demographic data (20 years) and recent developments in capture–recapture methodology. We found no evidence of any negative effects of the attached devices on the probability of survival, breeding, or breeding successfully in the current or following season in either males or females. We conclude that the current satellite transmitters and smaller devices used by researchers are valuable conservation and research tools that do not adversely affect the demographic traits of large albatrosses. Similar tests should be carried out on smaller species, which are more likely to be affected.

Barbraud Christophe, Weimerskirch Henri, . (2012). Estimating survival and reproduction in a quasi-biennially breeding seabird with uncertain and unobservable states
. Wilson J Ornithol, 152(2), 605–615-.
Abstract: Estimating the effects of environmental factors on the population dynamics of albatrosses is necessary for their conservation. This requires estimation of demographic parameters, long-time series of capture–recapture data, and knowledge of their at-sea distribution. For biennial albatrosses, multistate mark–recapture models (MSMR) considering individuals during their sabbatical year as unobservable could provide reliable estimates. However, this requires that state assignment is determined with certainty which may not be the case in historical data. We applied multievent mark–recapture models (MEMR) to data on adult Wandering Albatross (Diomedea exulans) at Possession Island collected between 1966 and 2006. The models accounted for state uncertainty for those breeding states where the breeding outcome was uncertain. Survival estimates obtained from models not accounting for temporary emigration were higher than those obtained from models accounting for temporary emigration. For males and females, survival estimates from the MEMR models were higher than those from CJS and MSMR models. Annual survival probability was 0.924 (SE = 0.034) for breeding females, 0.971 (SE = 0.038) for non-breeding females, 0.954 (SE = 0.018) for breeding males, and 0.938 (SE = 0.017) for non-breeding males. Whereas Wandering Albatrosses are generally considered as obligate biennial breeders, we found that the probability that successful breeders attempted to breed in a subsequent year was 0.069 for females and 0.048 for males, although their probability of success was 44–62% lower than that of individuals that skipped breeding.
