资源简介:
To date the seabird research program has: 1. Quantified how increases in El-Nino intensity and sea-surface temperatures (SST) result in decreased breeding participation, increased foraging effort, reduced food availability, poor chick growth and/or reproductive failure across multiple seabird species in both the northern and southern GBR. 2. Identified important seabird foraging areas/regions that the lie both within and outside the GBR region 3. Identified physiochemical and oceanographic correlates associated with both the important foraging areas and El-Nino/SST impacts 4. Examined the relative impacts of other anthropogenic and non-anthropogenic stressors such as cyclone frequency and tourist visitation rates at a key breeding site 5. Examined the ability of multiple pelagic foraging seabird species to copy with climate related changes in food availability via behavioural and/or developmental plasticity.

截至目前,本海鸟研究项目已完成以下工作: 1. 量化了厄尔尼诺(El Niño)强度升高与海表温度(sea-surface temperature, SST)上升,如何导致大堡礁(Great Barrier Reef, GBR)南北海域多种海鸟出现繁殖参与度下降、觅食投入增加、食物可获得性降低、雏鸟生长不良以及/或繁殖失败等问题。 2. 确定了分布于大堡礁海域内外的重要海鸟觅食区域。 3. 明确了与重要觅食区域以及厄尔尼诺/海表温度影响相关的物理化学与海洋学关联因子。 4. 在一处核心繁殖位点,探究了其他人为与非人为压力因子(如气旋发生频率、游客到访率)的相对影响。 5. 探究了多种远洋觅食海鸟物种通过行为与/或发育可塑性,应对食物可获得性随气候变化产生的变化的能力。 参考文献: - 德夫尼等(Devney et al.),2009年,《热带海鸟对厄尔尼诺前兆信号的敏感性》,《生态学》(Ecology),第90卷:1175-1183 - 康登等(Congdon et al.),2007年,《大堡礁海鸟对气候变化的脆弱性》,收录于约翰逊(Johnson J.)与马歇尔(Marshall P.)主编:《气候变化与大堡礁》,大堡礁海洋公园管理局(GBRMPA),堪培拉 - 欧文与康登(Erwin & Congdon),2007年,《海表温度日变化降低大堡礁乌燕鸥的觅食成功率》,《海洋生态学进展系列》(MEPS),第331卷:255-266 - 康登等(Congdon et al.),2005年,《热带鹱形目海鸟的双重觅食与协同育雏》,《海洋生态学进展系列》(MEPS),第301卷:293-301 - 佩克等(Peck et al.),2004年,《繁殖季内海表温度限制楔尾鹱的觅食成功率》,《海洋生态学进展系列》(MEPS),第281卷:259-266 - 史米瑟斯等(Smithers et al.),2003年,《海表温度升高降低了大堡礁南部楔尾鹱的育雏投入并引发繁殖失败》,《海洋与淡水研究》(Marine & Freshwater Research),第55卷:973-977
