首先我想指出,我只有非常基本的了解生态学、生物学和古生物学所以我很容易错过一些很简单。我可以想象某些方面海洋和陆地生态系统相互影响:1。河流和地表径流携带矿物、土壤、植物秸秆、畜禽粪便等进入海洋。富有成效的陆地生态系统将意味着更少的矿物质,更多有机营养物质进入海洋。2。陆栖动物(鸟类)吃海洋的土地然后排泄和食用。3所示。海洋和陆地生态系统吸收和大气成分,美元二氧化碳美元、甲烷、美元重新分配全球大气运动。也会影响气候,因此水循环。天真的我看来,形势很不对称。 While №2 should be of extreme importance to the coastal ecosystems I suppose it's influence drops quickly as you go deeper into continent aggravated by water currents taking everything back into ocean. So (again naively) it seems to me that marine ecosystems should be much more influenced by the terrestrial ones than the other way around. So imagine sudden significant drop of primary production for some reason constrained to the oceans. Obviously it would be a catastrophe for island and coastal life but in what ways, how much and at what timescale it will affect inland ecosystems? What if we turn it upside down and consider some significant drop of terrestrial primary production?
