Goniopteris ×tico (Thelypteridaceae), a new hybrid fern from Costa Rica

Goniopteris ×tico, a new hybrid fern from La Selva Biological Station in Heredia Province, Costa Rica, is described based on morphology and analysis of target-capture DNA sequence data. The hybrid co-occurs with its two putative progenitors, Goniopteris mollis and Goniopteris nicaraguensis, and is readily recognizable by its intermediate leaf dissection and venation. It is also intermediate in pinnae size and shape and presents irregularly lobed pinnae. Despite the broad overlap in the geographic distribution of its parental taxa, Goniopteris ×tico is only known from two collections from a single area of the La Selva Biological Station, highlighting the importance of close observation of ferns from even well-collected areas., , , # Goniopteris ×tico (Thelypteridaceae), a New Hybrid Fern from Costa Rica [https://doi.org/10.5061/dryad.9w0vt4bnr](https://doi.org/10.5061/dryad.9w0vt4bnr) This dataset includes FASTA files of multiple sequence alignments of 352 low-copy nuclear loci, as well as summary tables of the output of these analyses. ## Description of the data and file structure Accession names match supplementary data provided in the Zenodo repository: https://zenodo.org/records/7832162 **Table 1: Results of HybPhaser Analysis** **Key to column headers:** * Sample Number - Accession number from NCBI Sequence Read Archive * Voucher - Collector surname and collection number * Country - Country where voucher was collected * Taxon - species name * bp - Total base pair count * allele\_divergence - % sequence divergence calculated by HybPhaser * locus\_heterozygosity - Percentage of loci with heterozygosity scores above threshold * loci with >0.5% SNPs - Percentage of loci with >0.5% SNPs * loci with &g...Goniopteris ×tico，一种产自哥斯达黎加埃雷迪亚省拉塞尔瓦生物站的新型杂交蕨类，本研究基于形态学特征与目标捕获DNA序列数据分析对其进行正式描述。该杂交种与其两个推定亲本物种Goniopteris mollis与Goniopteris nicaraguensis同域分布，可凭借其处于中间型的叶片分裂方式与脉序便捷识别；其羽片的大小与形态同样呈现中间过渡特征，且具有不规则浅裂的羽片。尽管其亲本类群的地理分布范围存在广泛重叠，但Goniopteris ×tico目前仅在拉塞尔瓦生物站的单一区域内发现两份馆藏标本，这凸显了即便在采样较为充分的区域，对蕨类植物开展细致观测的重要性。 # Goniopteris ×tico（金星蕨科Thelypteridaceae），一种产自哥斯达黎加的新型杂交蕨类 https://doi.org/10.5061/dryad.9w0vt4bnr 本数据集包含352个低拷贝核基因座的多序列联配FASTA文件，以及上述分析结果的汇总表格。 ## 数据与文件结构说明 样本登录名与Zenodo仓储库中的补充数据匹配：https://zenodo.org/records/7832162 **表1：HybPhaser分析结果** **列标题说明：** * 样本编号：来自NCBI序列读取档案（Sequence Read Archive，SRA）的登录号 * 凭证标本：采集者姓氏与采集编号 * 采集国家：凭证标本的采集国 * 类群：物种名称 * 总碱基对数量：总碱基对总数 * 等位基因分化率：由HybPhaser计算得到的序列分化百分比 * 基因座杂合率：杂合性评分高于阈值的基因座所占百分比 * 单核苷酸多态性比例＞0.5%的基因座：单核苷酸多态性比例＞0.5%的基因座所占百分比 * loci with &g...
