Data and metadata for "Successful eradication of invasive American bullfrogs leads to co-extirpation of emerging pathogens"

There are 8 data files (csv) and 1 metadata file (.docx) linked with the manuscript: Hossack, Hall, Crawford, Goldberg, Muths, Sigafus, and Chambert. 2023. <strong>Successful eradication of invasive American bullfrogs leads to co-extirpation of emerging pathogens. Conservation Letters.</strong> <br> Individual Detection Files: There are 5 “..._detect” files (csv) with data representing whether DNA was detected on collected filters. Each of these files has columns for Site Code, Bullfrog Site, Site Type, and 9 columns indicating whether a filter was collected (represented by a 0 or 1; “-” = no filter collected) and whether DNA of target taxa was detected on that filter (0 or 1). The 5 file names indicate the target taxon (e.g., bullfrog_detect, ranaviruses_detect). Site Code: Numeric code representing a unique site. Site names are obscured because some are on private property and some host endangered species. BullfrogSite: Indicates whether a site was coded a priori as a site with bullfrogs. Yes= 1, No = 0. Site Type: Indicates whether a site was an eradication site (Treatment) or control site. pre_S1_....: Indicates whether a site was samples before (pre_) or after (post_) bullfrog eradication efforts occurred. There were up to 3 pre-eradication filter samples collected and up to 6 post-eradication samples. The end of the header (e.g., pre_s1_BF) indicates which taxon the results are for. Results from eDNA samples indicating whether target DNA was detected (1) or not (0) on a particular filter. There are 3 covariate files. <br> sample_covariates.csv Site Code: Numeric code representing a unique site. Site names are obscured because some are on private property and some host endangered species. Site Type: Indicates whether a site was an eradication site (Treatment) or control site. pre_S1..._VolFiltered....: Volume (mls) of water filtered for each eDNA filter collected. <br> sampling_dates.csv Site Code: Numeric code representing a unique site. Site names are obscured because some are on private property and some host endangered species. Site Type: Indicates whether a site was an eradication site (Treatment) or control site. pre_S1..._date....: Date (m/d/y) that a filter sample was collected. <br> site_covariates.csv Site Code: Numeric code representing a unique site. Site names are obscured because some are on private property and some host endangered species. BullfrogSite: Indicates whether a site was coded a priori as a site with bullfrogs. Yes= 1, No = 0. Site Type: Indicates whether a site was an eradication site (Treatment) or control site. fish_pres: Indicates whether a site was coded as hosting fishes or not. Yes= 1, No = 0. area_2016: Flooded extent (square meters) of sampled waterbody in fall/winter 2016. area_2020: Flooded extent (square meters) of sampled waterbody in winter 2020-2021. FilterType_2016: Indicates whether an eDNA sample was collected with a 0.45 uM filter or 5 uM filter in 2016. FilterType_2020: Indicates whether an eDNA sample was collected with a 0.45 uM filter or 5 uM filter in 2020-2021.

本数据集关联论文为Hossack、Hall、Crawford、Goldberg、Muths、Sigafus与Chambert于2023年发表于《Conservation Letters》的《Successful eradication of invasive American bullfrogs leads to co-extirpation of emerging pathogens》，包含8个逗号分隔值（Comma-Separated Values, CSV）数据文件与1个元数据文件（.docx）。

### 个体检测文件
包含5个格式为"*_detect"的CSV文件，用于记录采集滤膜上的DNA检出情况。每个文件均包含以下字段：站点编码（Site Code）、牛蛙站点（Bullfrog Site）、站点类型（Site Type），以及9列数据，分别代表滤膜是否被采集（以0或1表示，"-"代表未采集滤膜）与目标类群的DNA是否在该滤膜上被检出（0或1）。5个文件名分别对应其检测的目标类群（例如`bullfrog_detect`为牛蛙检测文件，`ranaviruses_detect`为蛙病毒检测文件）。
- 站点编码（Site Code）：代表唯一站点的数字编码。由于部分站点位于私人领地或保育有濒危物种，站点名称已做隐去处理。
- 牛蛙站点（Bullfrog Site）：表示该站点是否被预先编码为存在牛蛙的站点，取值为1（是）或0（否）。
- 站点类型（Site Type）：表示该站点为根除处理站点（Treatment）还是对照站点（Control）。
- 以`pre_S1_*`为前缀的字段：表示该站点的采样时间为牛蛙根除行动前（`pre_`）还是行动后（`post_`）。本研究最多采集3次根除前滤膜样本与6次根除后滤膜样本。表头后缀（例如`pre_s1_BF`）代表该列数据对应的目标类群。上述结果均来自环境DNA（environmental DNA, eDNA）样本，用于指示目标DNA是否在特定滤膜上被检出（1为检出，0为未检出）。

### 协变量文件
本数据集包含3个协变量文件：
1. `sample_covariates.csv`
- 站点编码（Site Code）：代表唯一站点的数字编码。由于部分站点位于私人领地或保育有濒危物种，站点名称已做隐去处理。
- 站点类型（Site Type）：表示该站点为根除处理站点（Treatment）还是对照站点（Control）。
- 以`pre_S1..._VolFiltered...`为前缀的字段：代表每一张采集的eDNA滤膜所过滤的水体体积（单位：毫升）。
2. `sampling_dates.csv`
- 站点编码（Site Code）：代表唯一站点的数字编码。由于部分站点位于私人领地或保育有濒危物种，站点名称已做隐去处理。
- 站点类型（Site Type）：表示该站点为根除处理站点（Treatment）还是对照站点（Control）。
- 以`pre_S1..._date...`为前缀的字段：代表滤膜样本的采集日期（格式为月/日/年）。
3. `site_covariates.csv`
- 站点编码（Site Code）：代表唯一站点的数字编码。由于部分站点位于私人领地或保育有濒危物种，站点名称已做隐去处理。

- 站点类型（Site Type）：表示该站点为根除处理站点（Treatment）还是对照站点（Control）。
- `fish_pres`字段：表示该站点是否被编码为有鱼类栖息，取值为1（是）或0（否）。
- `area_2016`：代表2016年秋冬季节采样水体的淹没范围（单位：平方米）。
- `area_2020`：代表2020-2021年冬季采样水体的淹没范围（单位：平方米）。
