Studies of the mechanisms underlying climate-induced population changes are critically needed to better understand and accurately predict population responses to climate change. Long-lived migratory species might be particularly vulnerable to climate change as they are constrained by different climate conditions and energetic requirements during the breeding and non-breeding seasons. Yet, most studies primarily focus on the breeding season of these species life cycle. Environmental conditions experienced in the non-breeding season may have downstream effects on the other stages of the annual life cycle. Not investigating such effects may potentially lead to erroneous inferences about population dynamics.\r\n2. Combining demographic and tracking data collected between 2006 and 2013 at Kerguelen Island on a long-lived migratory seabird, the Black-Browed Albatross (Thalassarche melanophris), we investigated the links between sea surface temperature during the non-breeding season and behavioural and phenological traits (at-sea behaviour and migratory schedules) while accounting for different responses between birds of different sex and reproductive status (previously failed or successful breeders). We then explored whether variation in the foraging behaviour and timing of spring migration influenced subsequent reproductive performance.\r\n3. Our results showed that foraging activity and migratory schedules varied by both sex and reproductive status suggesting different energetic requirements and constraints among individuals. Higher sea surface temperatures during late winter, assumed to reflect poor winter conditions, were associated with an earlier departure from the wintering grounds and an extended pre-breeding period. However, an earlier spring migration and an earlier return to Kerguelen grounds were associated with a lower breeding success.\r\n4. Our results highlighted that behaviour during some periods of the non-breeding season, particularly towards the end of the wintering period and the pre-breeding period, had a significant effect on the subsequent reproductive success. Therefore caution needs to be given to all stages of the annual cycle when predicting the influence of climate on population dynamics.", "east": 70.75, "geometry": ["POINT(69.625 -49.25)"], "keywords": "Albatross; Animal Behavior Observation; Antarctica; Biota; Birds; Black-Browed Albatross (thalassarche Melanophris); Field Investigations; Foraging; Kerguelen Island; Ocean Island/plateau; Ocean Island/Plateau; Southern Ocean", "locations": "Kerguelen Island; Antarctica; Southern Ocean", "north": -48.5, "nsf_funding_programs": "Antarctic Organisms and Ecosystems", "persons": "Jenouvrier, Stephanie", "project_titles": "Linking Foraging Behaviors to Demography to understand Albatrosses Population Responses to Climate Change", "projects": [{"proj_uid": "p0010002", "repository": "USAP-DC", "title": "Linking Foraging Behaviors to Demography to understand Albatrosses Population Responses to Climate Change"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -50.0, "title": "Linking oceanographic conditions, migratory schedules and foraging behaviour during the non-breeding season to reproductive performance in a long-lived seabird", "uid": "601140", "west": 68.5}, {"awards": "1041022 McClintock, James", "bounds_geometry": ["POLYGON((-64.5 -64.5,-64.45 -64.5,-64.4 -64.5,-64.35 -64.5,-64.3 -64.5,-64.25 -64.5,-64.2 -64.5,-64.15 -64.5,-64.1 -64.5,-64.05 -64.5,-64 -64.5,-64 -64.54,-64 -64.58,-64 -64.62,-64 -64.66,-64 -64.7,-64 -64.74,-64 -64.78,-64 -64.82,-64 -64.86,-64 -64.9,-64.05 -64.9,-64.1 -64.9,-64.15 -64.9,-64.2 -64.9,-64.25 -64.9,-64.3 -64.9,-64.35 -64.9,-64.4 -64.9,-64.45 -64.9,-64.5 -64.9,-64.5 -64.86,-64.5 -64.82,-64.5 -64.78,-64.5 -64.74,-64.5 -64.7,-64.5 -64.66,-64.5 -64.62,-64.5 -64.58,-64.5 -64.54,-64.5 -64.5))"], "date_created": "Fri, 20 Oct 2017 00:00:00 GMT", "description": "", "east": -64.0, "geometry": ["POINT(-64.25 -64.7)"], "keywords": "Antarctica; Antarctic Peninsula; Biota; Chemistry:fluid; Chemistry:Fluid; Sample/collection Description; Sample/Collection Description; Southern Ocean", "locations": "Antarctic Peninsula; Southern Ocean; Antarctica", "north": -64.5, "nsf_funding_programs": "Antarctic Organisms and Ecosystems", "persons": "Amsler, Charles; Schram, Julie", "project_titles": "The effects of ocean acidification and rising sea surface temperatures on shallow-water benthic organisms in Antarctica", "projects": [{"proj_uid": "p0000426", "repository": "USAP-DC", "title": "The effects of ocean acidification and rising sea surface temperatures on shallow-water benthic organisms in Antarctica"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -64.9, "title": "Data from Schram et al. 2017 MEPS", "uid": "601062", "west": -64.5}, {"awards": "1041022 McClintock, James", "bounds_geometry": ["POLYGON((-79 -60,-76.4 -60,-73.8 -60,-71.2 -60,-68.6 -60,-66 -60,-63.4 -60,-60.8 -60,-58.2 -60,-55.6 -60,-53 -60,-53 -61,-53 -62,-53 -63,-53 -64,-53 -65,-53 -66,-53 -67,-53 -68,-53 -69,-53 -70,-55.6 -70,-58.2 -70,-60.8 -70,-63.4 -70,-66 -70,-68.6 -70,-71.2 -70,-73.8 -70,-76.4 -70,-79 -70,-79 -69,-79 -68,-79 -67,-79 -66,-79 -65,-79 -64,-79 -63,-79 -62,-79 -61,-79 -60))"], "date_created": "Thu, 01 Jan 2015 00:00:00 GMT", "description": "The research will investigate the individual and combined effects of rising ocean acidification and sea surface temperatures on shallow-water calcified benthic organisms in western Antarctic Peninsular (WAP) marine communities. The Southern Ocean is predicted to become undersaturated in terms of both aragonite and calcite within 50 and 100 years, respectively, challenging calcification processes. Adding to the problem, antarctic calcified benthic marine organisms are more vulnerable to ocean acidification than temperate and tropical species because they are generally weakly calcified. Many antarctic organisms are essentially stenothermal, and those in the West Antarctic Peninsula are being subjected to rising seawater temperatures. The project employs both single-species and multi-species level approaches to evaluating the impacts of rising ocean acidification and seawater temperature on representative calcified and non-calcified macroalgae, on calcified and non-calcified mesograzers, and on a calcified macro-grazer, all of which are important ecological players in the rich benthic communities. Multi-species analysis will focus on the diverse assemblage of amphipods and mesogastropods that are associated with dominant macroalgae that collectively play a key role in community dynamics along the WAP. The project will support undergraduate research, both through NSF programs, as well as home university-based programs, some designed to enhance the representation of minorities in the sciences. The principal investigators also will support and foster graduate education through mentoring of graduate students.

Interpretation of the ANDRILL data suggests the West Antarctic Ice Sheet is highly sensitive to changes in Pliocene sea surface temperatures and this conclusion has been supported by recent Global Circulation Model results for the early to mid Pliocene. The PIs propose to model paleo-ice configurations and warm orbits associated with a WAIS collapse to assess potential climate change in East Antarctica. During such episodes of polar warmth they propose to answer: What is the limit of ablation along the East Antarctic Ice Sheet?; Are relict landforms in the Dry Valleys susceptible to modification from increase in maximum summertime temperatures?; and Is there sufficient increase in minimum wintertime temperatures to sustain a tundra environment in the Dry Valleys? Integration of depositional records and model outputs have the potential to test the performance of numerical models currently under development as part of ANDRILL; reconcile inconsistencies between marine and terrestrial paleoclimate records in high Southern Latitudes; and improve understanding of Antarctic climate and ice volume sensitivity to forcing for both the East Antarctic and West Antarctic Ice Sheets.
