评估礁对当前和未来海平面上升情景的抵御力.

主要方法:

使用地面激光扫描来调查季节性垂直珊瑚礁生长.
监测了群动态,包括的长度和丰度.
数据分析的重点是将珊瑚礁生长率与季节性环境和生物因素相关联.

主要成果:

珊瑚礁的平均增长率为每年19.8毫米 (Kaiserbalje) 和每年17.5毫米 (Nordland).
季节性贝生长率从0.03-0.06毫米/天 (冬季) 到0.10-0.16毫米/天 (夏季) 不同.
从2019年到2022年,的丰度平均为627印/平方米 (Kaiserbalje) 和338印/平方米 (Nordland).

结论:

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Primary Production

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
