Double-crested Cormorant (Nannopterum auritum) nesting colony and environmental data in Biscayne National Park, Florida, USA (2009-2024)

Double-crested Cormorant (DCCO) nesting data were collected from colonies in Biscayne National Park (BISC) by the South Florida/Caribbean Inventory and Monitoring Network as part of the Colonial Nesting Birds vital sign monitoring program. Nesting data collected from 2010 to 2023 are included in this dataset. Salinity, chlorophyll, and ammonia data were acquired from sites monitored in the Surface Water Quality Monitoring Program managed by the Miami-Dade County Division of Environmental Management’s Department of Regulatory and Economic Resources (RER-DERM). Seagrass data were acquired from sites monitored by RER-DERM as a part of the Biscayne Bay Benthic Habitat Monitoring Program. Mangrove fish and epifauna data were acquired from the U.S. National Oceanic and Atmospheric Administration's (NOAA) Integrated Biscayne Bay Ecological Assessment and Monitoring Project (IBBEAM). Environmental data (salinity, chlorophyll, ammonia, seagrass, mangrove fish, and epifauna) were manipulated in order to examine the relationship between DCCO nesting trends and the BISC ecosystem. This data package is completed. Code included is pertinent to the methods described in "Assessment of ecosystem health in Biscayne National Park, Florida according to Double-crested Cormorant (Nannopterum auritum) nesting trends" by Taylor et al. 2025, currently submitted to and under review by Ecological Indicators.

双冠鸬鹚（Double-crested Cormorant, DCCO）的筑巢数据由南佛罗里达/加勒比清单与监测网络，作为殖民地筑巢鸟类生命体征监测计划的组成部分，在比斯坎国家公园（Biscayne National Park, BISC）的筑巢种群栖息地收集。本数据集涵盖2010年至2023年的筑巢观测数据。
盐度、叶绿素及氨浓度数据取自迈阿密-戴德县环境管理部监管与经济资源局（RER-DERM）管理的地表水质监测计划监测站点。海草相关数据同样由RER-DERM负责监测的站点获取，属于比斯坎湾底栖生境监测计划的一部分。红树林鱼类及附生动物数据取自美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的比斯坎湾生态综合评估与监测项目（IBBEAM）。
为探究双冠鸬鹚筑巢趋势与比斯坎国家公园生态系统的关联，研究人员对上述环境数据（盐度、叶绿素、氨浓度、海草、红树林鱼类及附生动物）进行了处理分析。本数据包已编制完成，附带代码匹配Taylor等人2025年发表于《生态指标（Ecological Indicators）》（目前处于投稿审稿阶段）的论文《基于双冠鸬鹚（Nannopterum auritum）筑巢趋势评估佛罗里达州比斯坎国家公园生态系统健康状况》中所述的研究方法。
