Long-term climate change modulates aquatic-terrestrial ecological decoupling: a 240,000-year record from Lake Fúquene, Colombia

Description Multiproxy analysis of the 250-yr Lake Fuquene record (submitted to Ecography). This repository contains the necessary data and code to reproduce the statistical analyses and generate the main plots using the R software. Study area and datasets description Lake Fuquene: Pleistocene in origin, morrained-dammed tropical lake located in the Eastern Cordiellera of Colombian Andes. Water depth=2-6 m Two sediment cores, composite of 250 kyr diatom, geochemical and pollen record F9: 60-m long, sampled for diatom, pollen and geochemistry F7: sampled for diatoms and pollen (littoral) Main numerical steps: Clean data and estimate Principal Curves for each assemblage (pollen and diatoms) Plot stratigraphical floristic changes over time to identify periods of change Interpolate PrC from coarser, explanatory variables (aquatic and terrestrial PrC) to lower resolution, responsive variables (diatom abundances) resolution Functional diversity analyses: how changes in lake habitat size did influence niche occupation by functionally similar diatom assemblages? Distributed Hierarchical Generalized Additive Models (DHGAM) Folders scripts: series of analyses arranged in a sequential order, including functions data: individual files to read
