RATIONALE : Stable sulfur isotope compositions (δ 34S values) are a useful marker of terrestrial (lower δ 34S) versus marine (higher δ 34S) diets. In coastal areas, 34S‐enriched sea spray can obscure these marine/terrestrial differences. We sought to establish whether δ 34S values of sea spray‐affected terrestrial fauna can be distinguished from those of marine‐feeding terrestrial fauna.

吃海藻的绵羊表明,海洋喷雾的δ34S证据可以完全掩盖。

基本原理:稳定硫同位素组合物(δ 34个价值观)是地面(降低的有用标志物δ 34 S)海洋(较高的δ 34 S)饮食。在沿海地区,富含34 S的海水喷雾可以掩盖这些海洋/陆地差异。我们试图确定是否δ 34个海浪影响的陆生动物的价值观可以从这些海洋喂养陆地动物区分开来。
