Abstract: The eradication of invasive mammals on islands is important for protecting seabird populations and insular ecosystems. However, the impacts of such eradications are insufficiently known because monitoring of potentially beneficiary species is often sporadic and limited. We performed a survey of all seabird species on Saint-Paul Island, southern Indian Ocean, 20 years after successful eradication of invasive black rat (Rattus rattus) and European rabbit (Oryctolagus cuniculus). Using complementary sampling designs including adaptive cluster sampling, stratified random sampling and entire sampling, we estimated population changes and colonization by new seabird species. A total of 13 seabird species were found breeding on Saint-Paul post-eradication compared to six before the eradication. Among the seven species that colonized the island, five (MacGillivray’s prion Pachyptila macgillivrayi, fairy prion P. turtur, white-bellied storm petrel Fregetta grallaria, Antarctic tern Sterna vittata, sooty tern Onychoprion fuscatus) had relictual populations breeding on a nearby islet, and one (brown skua Catharacta antarctica) was a new breeding species. We also found breeding subantarctic little shearwaters Puffinus elegans. For species that were breeding on the Saint Paul pre-eradication, the mean annual population growth rate was 1.030 ± 0.093 (SE). Species known to be vulnerable to rat predation (prions, great-winged petrel Pterodroma macroptera, flesh-footed shearwater Puffinus carneipes, subantarctic little shearwater, white-bellied storm petrel, Antarctic tern) had the highest population growth rates. Two decades after the eradication of invasive mammals on a remote oceanic island, seabird populations were high beneficiaries. These findings further highlight the importance of invasive mammal eradication on islands as a conservation tool. Results are encouraging for the planned eradication of invasive mammals from nearby Amsterdam Island, and suggest this will mainly benefit terns and small burrowing petrels.

Abstract: “[Daniel Pauly] is an iconoclastic fisheries scientist ... who is so decidedly global in his life and outlook that he is nearly a man without a country.”—NEW YORK TIMES “Daniel Pauly is a friend whose work has inspired me for years.”—TED DANSONDaniel Pauly is a living legend in the world of marine biology. He coined the influential term “shifting baselines,” in which knowledge of environmental disaster fades over time, leading to a misguided understanding of our world. He blew the whistle on the global fishing industry, alerting the public to the devastation of overfishing. And he developed data-driven research methods that led to groundbreaking discoveries. Daniel Pauly is also a man whose life was shaped by struggle. Born after the Second World War to a white French woman and Black American GI in Paris, Pauly’s childhood has been described as Dickensian. His father left before he was born and his mother, whose family did not accept her and her mixed-race son, fell prey to a manipulative Swiss couple who abducted Pauly under murky circumstances. He was taken to Switzerland, where he was treated cruelly as the couple’s servant.  Pauly escaped to Germany to attend university and, as a young man, travelled to the United States during the 1969 civil rights movement, where he met his father’s family and experienced a political and racial reawakening. From there, he went on to have one of the most decorated careers in the field of marine biology. The Ocean’s Whistleblower “weaves together the challenges of marine research with an astonishing coming-of-age story” (Andrew Sharpless, Oceana) and is told through interviews with colleagues, friends, and Pauly himself. A brilliant book about a brilliant man, The Ocean’s Whistleblower finally profiles one of the most influential scientists of our time.

Abstract: Mammals constitute a group of vertebrates that share a number of unique characteristics,such as nursing their young with milk, and having hair. The pattern of low mammal species diversity in the Arctic probably reflects a combination of mainly two driving factors: first, being homeotherms, mammals require a substantial amount of energy to sustain the various life processes, and the arctic regions are characterized by a very low availability of energy due to short seasons for primary production. Secondly, the occurrence of arctic mammals today reflects the reinvasion of the mammal species into the Arctic as the ecosystems were re-established following the deglaciation. This chapter discusses the characteristics of the arctic mammals, including their unique adaptations to life, and their role as both consumer and food base in the arctic ecosystems. Climate change in the Arctic may also alter the interactions within food webs.
