In vivo Growth Data

In vivo Growth Data.csv, Data description: Data used to create Figure 4: Average growth rate of evolved strains within a host (G. mellonella) relative to the ancestral strain. Data was collected in the laboratory. Columns correspond to: Strain Replicate: the name allocated to each of the replicate lines, e.g. H1 corresponds to replicate line 1 evolved on hard agar. In vivo Replicate: The in vivo growth rate production was measured independently four times in order to provide replicates. This value was averaged in statistical analysis. Agar Type on which Strain was Evolved: Strains were either evolved in hard or liquid agar. In vivo Relative to Ancestor: In vivo growth rate of evolved strain under each treatment group was divided by In vivo growth rate of ancestral strain under the same treatment to give a relative measurement of area dispersed. Averaged In vivo Replicates: Replicate relative in vivo growth rate measurements were averaged. Selection Type: Strains were either under positive or neutral artificial selection for dispersal. Caterpillar Fresh Weight: The weight of each caterpillar was measured before inoculation to control for the effects of caterpillar size on bacterial growth.

体内生长数据集（In vivo Growth Data.csv），数据说明：本数据集用于构建图4：宿主大蜡螟（G. mellonella）体内进化菌株相对于祖先菌株的平均生长速率。实验数据采集于实验室环境。各列对应信息如下：
1. 菌株重复株系（Strain Replicate）：为每个重复进化株系分配的标识名称，例如H1代表在硬琼脂上进化得到的第1株重复株系。
2. 体内重复测定（In vivo Replicate）：为获得可靠的重复实验结果，体内（in vivo）生长速率的测定独立重复了4次，该值将在统计分析中取平均。
3. 菌株进化所用琼脂类型（Agar Type on which Strain was Evolved）：菌株的进化培养环境分为硬琼脂或液体琼脂两类。
4. 相对于祖先菌株的体内生长速率（In vivo Relative to Ancestor）：将各处理组下进化菌株的体内生长速率，除以同一处理组下祖先菌株的体内生长速率，以此得到菌株扩散面积的相对量化值。
5. 体内重复测定平均值（Averaged In vivo Replicates）：对重复测定的体内生长速率相对值取平均后得到的结果。
6. 选择类型（Selection Type）：菌株在扩散性状上接受正向人工选择或中性人工选择。
7. 幼虫鲜重（Caterpillar Fresh Weight）：接种前测定每头幼虫的鲜重，以控制幼虫个体大小对细菌生长的影响。
