Database of species recorded in standardized collections in the Adolpho Ducke Forest Reserve

Dataset DescriptionThis dataset contains information on the abundance of Odonata species collected at different sampling points within the <b>Adolpho Ducke Forest Reserve</b>, located in Central Amazonia, Brazil. The data were collected over multiple years as part of standardized biodiversity surveys.The dataset comprises <b>76 sampling units</b>, each corresponding to a specific site and year combination. It includes <b>37 species of Odonata</b>, represented in columns with their respective abundance counts.<b>Columns:</b><code>SPECIES</code>: Sampling point code.<code>ANO</code>: Year of sampling.The remaining 37 columns correspond to the abundance of individual Odonata species recorded in each sample.The species list includes representatives from different families of damselflies and dragonflies, such as <i>Argia meioura</i>, <i>Hetaerina amazonica</i>, <i>Mnesarete astrape</i>, <i>Chalopteryx scintillans</i>, <i>Erythemis attala</i>, <i>Microstigma rotundatum</i>, and <i>Triacanthagyna caribbea</i>, among others.This dataset can be used for studies on temporal and spatial patterns of Odonata communities, assessments of biodiversity change, and analyses of the effects of environmental variation on aquatic insect assemblages.

数据集描述
本数据集收录巴西亚马孙中部地区<b>阿道夫·杜克森林保护区（Adolpho Ducke Forest Reserve）</b>内不同采样点采集的<b>蜻蛉目（Odonata）</b>物种丰度信息，数据依托标准化生物多样性调查项目历时多年收集完成。
本数据集包含<b>76个采样单元</b>，每个单元对应特定采样地点与采样年份的组合，共收录<b>37种蜻蛉目物种</b>，各物种的个体丰度以对应列项呈现。

<b>列项说明：</b>
<code>SPECIES</code>：采样点编码。
<code>ANO</code>：采样年份。
其余37个列项分别对应各采样单元中记录的单个蜻蛉目物种的丰度数值。

本次收录的物种涵盖豆娘与蜻蜓所属的多个类群，包括<i>Argia meioura</i>、<i>Hetaerina amazonica</i>、<i>Mnesarete astrape</i>、<i>Chalopteryx scintillans</i>、<i>Erythemis attala</i>、<i>Microstigma rotundatum</i>及<i>Triacanthagyna caribbea</i>等。

本数据集可用于蜻蛉目群落时空分布格局研究、生物多样性变化评估，以及环境变异对水生昆虫群落的影响分析。
