Laboratory experiments to determine herbivory of submerged vegetation exposed to oil

This dataset reports on the preferences of two estuarine herbivores (grass shrimp Palaeomonetes pugio and amphipod Gammarus mucronatus) for submerged vegetation (widgeongrass Ruppia maritima) grown in 4 different concentrations of oil: none (0 mL oil/L tank volume), low (0.26 mL oil/L tank volume), medium (0.53 mL oil/L tank volume), and high (1.05 mL oil/L tank volume). Carbon:Nitrogen ratios of plants and proportion loss of plant material after feeding by herbivores are presented for two experiments: 1) paired choice comparisons, and 2) foraging rate determination. All experiments were conducted in the laboratory at Louisiana State University. Related measurement, oil analysis, and cohesion data can be found in GRIIDC dataset R1.x139.143:0047.

本数据集记录了两种河口草食性动物——草虾（Palaeomonetes pugio）与端足类（Gammarus mucronatus）对不同石油浓度下培育的沉水植被川蔓藻（Ruppia maritima）的取食偏好。实验设置了4组石油浓度梯度：无石油组（0 mL油/升养殖槽体积）、低浓度组（0.26 mL油/升养殖槽体积）、中浓度组（0.53 mL油/升养殖槽体积）以及高浓度组（1.05 mL油/升养殖槽体积）。本数据集包含两项实验的相关数据：1）配对选择比较试验，2）觅食速率测定，具体指标为植物的碳氮比以及草食动物取食后植物材料的损失比例。所有实验均于路易斯安那州立大学实验室开展。相关测量、石油分析及内聚性数据可在GRIIDC数据集R1.x139.143:0047中获取。
