Tropical Seabird Biology and Conservation
Drs. David Hyrenbach (email@example.com) & Scott Shaffer (Scott.Shaffer@sjsu.edu)
The last two decades have seen a burgeoning of information on the general ecology, distribution, physiology, and population demography of temperate and high latitude seabird species. These advances have been driven by long-term colony-based and at-sea studies throughout the world (e.g. England, France, New Zealand, Australia, Japan, Norway, and USA). In contrast, comparable programs focusing on subtropical and tropical seabird species are far fewer, particularly with regard to at-sea distribution, individual movements and population dynamics. Initially, seminal studies by Fisher, Whittow, Ashmole, Schreiber, and others, focused on the adaptations of seabirds to foraging on low productivity tropical oceans. More recently, the surging interest in tropical seabirds is born out of the desire to understand the seabird distribution in relation to year-to-year variability in food availability, interactions with tuna fisheries, and the looming effects of increasing water temperature and rising sea level from the anticipated climate change. Given the venue of this year’s conference, we felt it was appropriate to host a session devoted to tropical seabirds.
To this end, we will convene a special paper session (SPS) highlighting the biology of tropical seabirds, with an emphasis on novel perspectives that increase our understanding of their ecology and their roles in marine ecosystems, and comparative studies that review differences between tropical and higher latitude species. The SPS will include an introductory talk and a 2-hour (8- paper) session, incorporating invited speakers and relevant contributed abstracts of presentations that fit within the realm of tropical seabird biology. Please note that the length of the proposed SPS may be lengthened / shortened to accommodate the scientific program and meeting schedule.
Where Seabirds and Tuna Meet: Biology and Management of Subsurface Predator Facilitated Foraging
Dr. Sara Maxwell (firstname.lastname@example.org), Dr. Lance Morgan (email@example.com), and Peter Kappes (firstname.lastname@example.org)
Seabirds occupy diverse foraging niches throughout their ranges that, in some cases, result in complex ecological interactions. One such example is subsurface predator facilitated foraging, the interaction between seabirds and subsurface predators where predators drive forage species to the surface making prey more accessible to seabirds. This interaction is known to occur in many of the world’s oceans including the Eastern Tropical Pacific, Northwest Atlantic, and throughout the Indian Ocean. In some regions of the world, such as the oligotrophic Central Tropical Pacific, some tropical seabird species are thought to be obligate commensal foragers with subsurface predators, a relationship that is of even greater importance during the breeding season. This indicates the importance of managing to foster this relationship in order to maintain or increase seabird populations, and has become a central management question to a number of agencies, particularly those that manage the US Pacific Remote Islands Marine National Monument.
Despite the importance of this relationship, however, our in-depth understanding of the interaction, as well as the key ecological knowledge of species involved in the interaction is poor, particularly in regards to questions most pertinent to management such as: Which seabird species are obligate foragers in relationship to subsurface predators? What is the range of seabird species movements, particularly during the breeding season when their movements are most restricted? What is the scale of local versus regional movements of subsurface predators and how does this influence the ability of seabirds to forage effectively? How does reduction in subsurface predator biomass – either locally or regionally – influence the availability of forage fish for seabirds and how does this translate to seabird breeding success?
Because many subsurface predators such as tunas are also commercially important species, management of this interaction becomes increasingly complex both biologically and socio-economically. Through a series of presentations followed by an in-depth discussion period, we will focus on biological questions directly relevant to management. Our goals are to: (1) present what is known about subsurface predator facilitated foraging, and classify our major gaps in understanding; (2) highlight how this interaction varies globally; (3) determine critical research questions and methods we can use to understand the interaction, and (4) determine how we can use existing data and the future answers to key question to manage both seabird species, fisheries and the ecosystems in which they interact.
Biology and Conservation of Hawai`i’s Endemic Seabirds: Hawaiian Petrel and Newell’s Shearwater
Dr. Helen James (email@example.com), Dr. Nick Holmes (firstname.lastname@example.org)
Two species of seabirds breed exclusively in the main Hawaiian Islands: the endangered Hawaiian Petrel (Pterodroma sandwichensis) and the threatened Newell’s Shearwater (Puffinus newelli). Recent research on the petrel has for the first time: tracked movements of individual birds at sea, traced patterns of gene flow among colonies, compared foraging behavior among colonies using stable isotopes, and compared vocalizations and morphology among islands. In addition, ancient DNA and stable isotopes from museum specimens and subfossil bones have extended the record of Hawaiian Petrel foraging ecology and genetic structure thousands of years into the past. Similar research is either in the planning stages or in progress for Newell’s Shearwater. This basic research draws attention to the need to consider each island colony separately, and to link the lives of these birds at sea with what happens at their breeding colonies in order to assess their conservation threats. The historical records provide a unique view of how human harvesting has affected the diets of non-target pelagic predators in the topical to temperate Pacific Ocean. Population estimates for these seabirds show that the fates of colonies may differ. For example, Newell’s Shearwater appears to be in rapid decline on Kaua`i whereas a larger than expected colony of Hawaiian Petrel was rediscovered not many years ago on Lana`i. Conservation programs for these seabirds include efforts to monitor population sizes and reproductive success, protect the birds from alien predators, and rescue birds that have been downed by lights and other human infrastructure. The special paper session will highlight research and conservation progress as well as future challenges for Hawai`i’s endemic seabirds.
Seabirds, marine spatial planning, and impacts of renewable energy development in the California Current Ecosystem
Dr. Jeannette Zamon (email@example.com)
Development of clean, renewable ocean energy sources is a high priority for growing energy demand on the US West Coast. The coastal waters of California, Oregon, and Washington are all part of the California Current Ecosystem, a highly productive marine ecosystem which supports millions of seabirds as well as providing a migratory corridor for non-resident seabirds, shorebirds, and waterfowl. Energy devices to harvest tidal, wave, or wind energy are already being tested in areas occupied by birds. Deployment of devices may directly or indirectly affect seabirds; evaluation of such effects is in very early stages. Minimizing undesirable impacts on birds requires data on seabird distribution, abundance, and habitat use. Data are necessary to inform the site-selection process, to evaluate before/after comparisons at individual sites, and to determine cumulative impacts across multiple sites.
Agency and NGO interest in seabirds and marine spatial planning for the California Current Ecosystem is reaching a critical mass. The goals of this Special Paper Session are to (1) highlight emerging priorities, needs, and data sets relevant to seabirds and marine spatial planning in California, Oregon, and Washington (2) provide a topical session that facilitates coast-wide networking among academics, agency scientists, NGOs, and consultants who contribute seabird data to marine spatial planning throughout the California Current and (3) discuss near-term research priorities and data gaps.
