Invasive species - American bullfrog (Lithobates catesbeianus) in Flanders, Belgium

Invasive species - American bullfrog (Lithobates catesbeianus) in Flanders, Belgium is a species occurrence dataset published by the Research Institute for Nature and Forest (INBO). The dataset contains over 7,500 occurrences (25% of which are American bullfrogs) sampled between 2010 until now, in the months April to October. The data are compiled from different sources at the INBO, but most of the occurrences were collected through fieldwork for the EU co-funded Interreg project INVEXO (http://www.invexo.eu). In this project, research was conducted on different methods for the management of American bullfrog populations, an alien invasive species in Belgium. Captured bullfrogs were almost always removed from the environment and humanely killed, while the other occurrences are recorded bycatch, which were released upon catch (see bibliography for detailed descriptions of the methods). Therefore, caution is advised when using these data for trend analysis, distribution range calculation, or other. Issues with the dataset can be reported at https://github.com/inbo/data-publication/tree/master/datasets/invasive-bullfrog-occurrencesWe strongly believe an open attitude is essential for tackling the IAS problem (Groom et al. 2015). To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). We would appreciate it however if you read and follow these norms for data use (http://www.inbo.be/en/norms-for-data-use) and provide a link to the original dataset (https://doi.org/10.15468/2hqkqn) whenever possible.

比利时佛兰德斯地区的美国牛蛙（Lithobates catesbeianus）入侵物种观测数据集，由比利时自然与森林研究所（Research Institute for Nature and Forest, INBO）发布。该数据集收录了超过7500条物种观测记录（其中25%为美国牛蛙），采样时间范围为2010年至今，观测月份集中在4月至10月。该数据集的数据整合自INBO的多个来源，但绝大多数观测记录来源于欧盟联合资助的Interreg项目INVEXO（http://www.invexo.eu）的野外调查工作。本项目针对比利时外来入侵物种美国牛蛙的种群管理方法开展了相关研究：项目中捕获的美国牛蛙几乎均会被带离原生境并实施人道灭杀，而其余记录的个体均为误捕个体，捕获后会被放归原生境（相关调查方法的详细说明请参阅参考文献）。因此，若将该数据集用于种群趋势分析、分布范围测算等研究场景，请谨慎使用。若您发现该数据集存在相关问题，可通过https://github.com/inbo/data-publication/tree/master/datasets/invasive-bullfrog-occurrences提交反馈。我们坚信，秉持开放态度是应对外来入侵物种（Invasive Alien Species, IAS）问题的关键所在（Groom等人，2015年）。为便于所有人均可使用该数据集，我们已将其置于公共领域，采用CC0（知识共享零协议，http://creativecommons.org/publicdomain/zero/1.0/）进行授权。不过，若您能遵守数据使用规范（http://www.inbo.be/en/norms-for-data-use）并尽可能附上原始数据集的链接（https://doi.org/10.15468/2hqkqn），我们将不胜感激。若您将该数据集用于学术论文研究，请按照相关引用规范对本数据集进行引用，或考虑邀请我们作为共同作者。我们始终乐于了解您对该数据集的使用或可视化方式，若您需要更多相关信息，可通过元数据中提供的联系方式与我们取得联系：[e-mail] 或 https://twitter.com/LifeWatchINBO。
