Core - invert biomass + ordinal sort
收藏资源简介:
Description: The Core Insect Pitfall/Malaise Trapping program has been running since 2012. The novel method was first developed by Robert M Ewers. This provides not only insect specimens, but other invertebrates such as myriapods, collembola, arachnids, and occasionally provides vertebrates such as small rodents, snakes, and amphibians. All specimens and data is kept as part of the Core of the SAFE project. The majority of the data which has been exploited so far remains with the Coleoptera and Staphylinidae groups, while much of the preliminary field iding groupings are currently not used, the data remains to have serious as of yet untapped potential for future workers.Trap construction:Traps were based on a design combining pitfall, flight-interception, and malaise traps. Flying insects were directed either upwards into a "top" trap or downwards into a "bottom" trap. Components used in the construction of each trap are as follows:• 1 25cm diameter, 20cm depth, 4.5cm spout aperture Blue Plastic "top" funnel.• 1 20cm diameter, 20cm depth, 2cm spout aperture Blue Plastic "bottom" funnel.• 1 Xcm four pointed star cloth, acting as a malaise tent "director", held at approximately 90 degrees to the trap with clear fishing line.• 1 Xcm diameter, 90 degree grey plastic elbow pipe, one end modified to include appropriate teeth to screw collection bottle onto which.• 1 Xml "bottom" collection bottle, modified with mesh lined holes to allow water to escape to prevent overspilling.• 1 Xml "top" collection bottle, unmodified.• 1 77cm length cross-intersecting clear plastic (PVC) flight interception vane, supported by 4 (metal) 68.5cm aluminum poles.• 8 white plastic Zip-Ties.• 70% ethanol solution to fill the collection bottles.Trapping strategy:The pitfall style bottom trap are dug flush into the ground where possible and the hole preserved between trapping periods to limit catch bias associated with soil and leaf litter disturbance (Digweed et al. 1995). Once constructed, and occasion start time recorded, the traps are left for three days before collection with collection time also recorded.Samples are then stored in a chest freezer at -10 degC, before being taken to Maliau Basin research station and sorted by order and 70% ethanol before again being stored in freezers.Justifications:This combination of traps is implemented to target invertebrates of various morphology and behaviour to take full advantage of the sampling opportunity.

### 数据集描述 本核心昆虫陷阱/马氏网诱捕计划自2012年起正式启动,其创新诱捕方案由Robert M Ewers首次研发。该计划不仅可采集昆虫标本,还能获取多足类、弹尾虫、蛛形类等多种无脊椎动物,偶尔亦可捕获小型啮齿类、蛇类、两栖类等脊椎动物。所有标本与相关数据均作为SAFE项目的核心资料进行留存。目前已得到利用的多数数据集中于鞘翅目(Coleoptera)与隐翅虫科(Staphylinidae)类群,而大量初步野外鉴定的类群分组尚未得到充分应用,该数据集仍具备巨大的未开发潜力,可供后续研究者深入挖掘。 #### 诱捕装置结构 本类诱捕装置结合了陷阱法、飞行拦截法与马氏网诱捕的设计原理,可将飞行昆虫引导至上方的“顶部”收集单元或下方的“底部”收集单元。每个诱捕装置的组成部件如下: • 1个直径25cm、深度20cm、导流口孔径4.5cm的蓝色塑料“顶部”漏斗。 • 1个直径20cm、深度20cm、导流口孔径2cm的蓝色塑料“底部”漏斗。 • 1块Xcm规格的四角星型布幕,作为马氏网的“导向幕”,通过透明鱼线固定为与诱捕装置呈约90°的夹角。 • 1根直径Xcm、90°的灰色塑料弯头,其中一端经过改造,带有适配螺纹以连接收集瓶。 • 1个Xml容量的“底部”收集瓶,瓶身开孔并衬有滤网,用于排出积水以防止液体溢出。 • 1个Xml容量的“顶部”收集瓶,未经过改装。 • 1片长77cm的交叉型透明聚氯乙烯(PVC)飞行拦截板,由4根金属制68.5cm长的铝制支撑杆支撑。 • 8根白色塑料扎带。 • 70%乙醇溶液,用于注入收集瓶作为保存液。 #### 诱捕方案 底部陷阱采用陷阱法布设,尽可能将其与地面齐平,并在两次诱捕周期之间保留坑洞,以减少因翻动土壤和落叶层带来的采样偏差(Digweed等,1995)。装置搭建完成并记录起始时间后,将诱捕装置放置三天再进行回收,同时记录回收时间。 采集后的样本被储存在-10℃的卧式冰柜中,随后转运至马里乌盆地(Maliau Basin)研究站,按类群分类并使用70%乙醇保存,之后再次放入冰柜储存。 #### 设计依据 本组合式诱捕装置旨在针对不同形态与行为习性的无脊椎动物进行采样,以充分利用此次采样机会。 #### 项目背景 本数据集作为以下SAFE研究项目的一部分采集:甲虫群落多样性的空间尺度效应研究 #### 资助信息 本数据的采集受以下机构资助: 森美达比(Sime Darby)(标准资助项目,SAFE-核心数据,编号未标注) 本数据集采用CC-BY 4.0许可协议发布,要求您在任何产出成果中引用本数据集,并额外要求您在成果中鸣谢上述资助机构的贡献。 #### 采集许可 本数据的采集已获得以下主管部门的许可: 沙巴生物多样性委员会(Sabah Biodiversity Council)(研究许可编号未标注) #### XML元数据 符合GEMINI标准的本数据集元数据可在此处获取 #### 数据文件说明 本数据集仅包含1个文件:Core_insect_2011_2012_2017.xlsx 该文件包含数据集元数据与2个数据表: 1. **昆虫分类统计(对应工作表"Insect_sorting")** 说明:2011、2012及2017年昆虫分类统计数据 字段数量:28个 数据行数:2502条 字段详情: TrapNo:陷阱编号(字段类型:标识符) Fragment:SAFE景观中的斑块编号(字段类型:标识符) Plot:昆虫采样点(字段类型:位置) Top_Bottom:陷阱内安装位置(字段类型:分类变量) DateColl:陷阱回收日期(字段类型:日期) TimeColl:陷阱回收时间(字段类型:时间) Coleoptera:鞘翅目个体丰度(字段类型:丰度) Staphylinids:隐翅虫科个体丰度(字段类型:丰度) Formicidae:蚁科个体丰度(字段类型:丰度) Isoptera:等翅目个体丰度(字段类型:丰度) Others_Insects_Invertebrate:其他无脊椎动物个体丰度(字段类型:丰度) Spider:蜘蛛个体丰度(字段类型:丰度) Woodlice:潮虫个体丰度(字段类型:丰度) Centipide_Milipide:多足类(蜈蚣/马陆)个体丰度(字段类型:丰度) Lizard:蜥蜴个体丰度(字段类型:丰度) Snake:蛇类个体丰度(字段类型:丰度) Mouse:啮齿类个体丰度(字段类型:丰度) Frog:蛙类个体丰度(字段类型:丰度) Worm:环节动物个体丰度(字段类型:丰度) Snail:软体动物(蜗牛)个体丰度(字段类型:丰度) Other_animal:其他动物个体丰度(字段类型:丰度) WetWeight:样本湿重(字段类型:数值型) DateSort:样本分类日期(字段类型:日期) Sorter:分类人员姓名(字段类型:备注) DateEnter1:第一次数据录入日期(字段类型:日期) EnteredBy1:第一次数据录入人员姓名(字段类型:备注) DateEnter2:第二次数据录入日期(字段类型:日期) EnteredBy2:第二次数据录入人员姓名(字段类型:备注) 2. **类群数量统计(对应工作表"Order_counts")** 说明:2011及2012年类群数量统计数据 字段数量:10个 数据行数:1977条 字段详情: Site:陷阱采样点(字段类型:位置) Position:枯落物样本采集位置(字段类型:分类变量) DateColl:陷阱回收日期(字段类型:日期) N_days:诱捕持续天数(字段类型:数值型) missing_data:是否存在缺失数据?(字段类型:分类变量) Coloptera:鞘翅目个体数量(字段类型:丰度) Staphylinid:隐翅虫科个体数量(字段类型:丰度) Formicidae:蚁科个体数量(字段类型:丰度) Isoptera:等翅目个体数量(字段类型:丰度) Other:其他无脊椎动物个体数量(字段类型:丰度) 数据时间范围:2011-01-11 至 2018-11-07 纬度范围:4.5000 至 5.0700 经度范围:116.7500 至 117.8200 分类学覆盖范围:所有类群名称均已通过GBIF核心分类法进行验证。若数据集使用了异名,则会先显示接受学名,再以括号标注数据集使用的异名。无法验证的类群(包括新种及其他未知类群、形态种、功能群以及GBIF核心分类法未收录的分类层级)将以方括号标注。 分类层级: - 动物界(Animalia) - 环节动物门(Annelida) - 节肢动物门(Arthropoda) - 多足类(Centipide_Milipide) - 昆虫纲(Insecta) - 鞘翅目(Coleoptera) - 隐翅虫科(Staphylinidae) - 蜚蠊目(Blattodea) - 等翅下目(Isoptera,注:原分类等翅目现已并入蜚蠊目,此处保留原文标注) - 膜翅目(Hymenoptera) - 蚁科(Formicidae) - 蛛形纲(Arachnida) - 蜘蛛目(Araneae) - 软甲纲(Malacostraca) - 等足目(Isopoda) - 潮虫(Woodlice) - 脊索动物门(Chordata) - 爬行纲(Reptilia) - 有鳞目(Squamata) - 蛇类(Snake) - 哺乳纲(Mammalia) - 啮齿目(Rodentia) - 两栖纲(Amphibia) - 无尾目(Anura) - 软体动物门(Mollusca) - 腹足纲(Gastropoda) (注:原文重复了一次上述分类层级,此处保留原貌)
