Luquillo LTER signature Monthly and Daily dataset

This dataset contains population, meteorological, phenological, and chemical data collected from tropical montane stream and forest ecosystems.
This synthesis product merges 11 distinct datasets into a single comprehensive resource, facilitating easier comparison and study of diverse ecological data.
Try our data explorer [here.](https://luqshiny.lter.network/sigds/) It provides a multi-faceted dataset essential to enhance biodiversity monitoring, ecosystem management, and global change research. Data spans from 1975 to 2024, with some gaps and missing data points. Particularly at the beginning of the time span measurements started with temperature and rainfall before other dataset collections began with the inception of the LUQ LTER in the late 1980s.
For phenology 17 species were selected for inclusion, listed below. 11 dominant species as described in Uriarte et al. 2009 (DOI 10.1890/08-0707.1). As well as in decline species PALRIP- Palicourea riparia and CISVER - Cissus verticillata. Species that show
a strong response to hurricanes PHYRIV - Phytolacca rivinoides- an understory herb and IPOTL -Ipomoea tiliacea- Morning glory vine. And a species thriving understory shrub SMIDOM - Smilax domingensis.
- **From Uriarte et al. 2009 these 11 species represent 75% of the stems >=10 cm dbh in the LFDP plot: **
- **ALCLAT** - Alchornea latifolia
- **CASARB** - Casearia arborea
- **CECSCH** - Cecropia schreberiana
- **DACEXC** - Dacryodes excelsa
- **GUAGUI** - Guarea guidonia
- **INGLAU** - Inga laurina
- **MANBID** - Manilkara bidentata
- **PREMON** - Prestoea montana
- **SCHMOR** - Schefflera morototoni
- **SLOBER** - Sloanea berteriana

本数据集涵盖采集自热带山地溪流与森林生态系统的种群、气象、物候及化学数据。

本整合型资源将11个独立数据集整合为一套统一的综合数据集，便于开展多样化生态数据的对比与研究工作。

请通过[此处](https://luqshiny.lter.network/sigds/)试用我们的数据探索器。该数据集具备多维度特征，可为生物多样性监测、生态系统管理及全球变化研究提供关键支撑。数据集时间跨度为1975年至2024年，存在部分数据缺口与缺失值。尤其在时间序列初期，仅开展了温度与降雨的观测，其余数据集的收集工作始于20世纪80年代末LUQ长期生态研究计划（LUQ LTER）启动之时。

本次物候观测共选取17个物种纳入分析，具体如下：依据Uriarte等人2009年的研究（DOI 10.1890/08-0707.1）确定的11个优势物种，此外还包括三类特殊类群：种群衰退物种PALRIP（*Palicourea riparia*）与CISVER（*Cissus verticillata*）；对飓风响应显著的物种PHYRIV（*Phytolacca rivinoides*，林下草本）与IPOTL（*Ipomoea tiliacea*，树牵牛藤）；以及林下优势灌丛物种SMIDOM（*Smilax domingensis*）。

**根据Uriarte等人2009年的研究，这11个物种占LFDP样地内胸径≥10厘米植株总数量的75%：**
- **ALCLAT**：*Alchornea latifolia*
- **CASARB**：*Casearia arborea*
- **CECSCH**：*Cecropia schreberiana*
- **DACEXC**：*Dacryodes excelsa*
- **GUAGUI**：*Guarea guidonia*
- **INGLAU**：*Inga laurina*
- **MANBID**：*Manilkara bidentata*
