Bob Merritt dataset of Nottinghamshire invertebrates

The great majority of records are of wetland invertebrates, especially water beetles and water bugs, with a significant minority being of spiders, rove beetles, ground beetles, dragonflies and molluscs, plus a few other groups. Almost all records have been generated during the past 25 years by the fieldwork of Bob Merritt, the exception being a small number of Environment Agency records, the IDs of which were determined/confirmed by him.绝大多数记录涉及湿地无脊椎动物，尤以水甲虫和水生蝽类为主，另有相当数量的记录涵盖蜘蛛、隐翅虫、步甲、蜻蜓及软体动物，此外还包括少量其他类群。几乎所有记录均由Bob Merritt在过去25年间通过野外调查生成，仅有少量环境署（Environment Agency）记录为例外，这些记录的标识符（IDs）均由他鉴定/确认。
