Mast seeding in European beech (Fagus sylvatica L.) is associated with reduced fungal sporocarp production and community diversity

A time series of seed production data from European beech (Fagus sylvatica) was combined with a fungal census (1977 to 2006) from La Chanéaz Fungus Reserve to evaluate the relationship between mast seeding and fungal resource availability. Annual fungal species' counts, traits, contemporaneous weather and seed production data are available here, alongside the code used to complete the analyses., The fungal census was conducted in the 75-hectare La Chanéaz Fungal Reserve, established in 1975, near Payerne, Switzerland (Swiss Federal Institute for Forest, Snow and Landscape Research WSL; 46 degrees 47’ 55” to 46 degrees 48’ 10” N and 6 degrees 59’ 52” to 7 degrees 00’ 30” E (Straatsma et al. 2001). The site is an old-growth forest on the Swiss Central Plateau (mean altitude 585-m), dominated by multi-story beech (Fagus sylvatica), with interspersed spruce (Picea abies), larch (Larix decidua), oak (Quercus robur), pine (Pinus sylvestris and Pinus strobus), maple (Acer pseudoplatanus) and ash (Fraxinus excelsior) growing on calcaric cambisol. The study area was enclosed by 2-m fences to deter mushroom pickers and other animals from harvesting the fruiting fungi. From 1975–2006, a total of 115,417 epigeous sporocarps from fungi with macroscopic sporocarps were recorded and identified. Surveys were conducted on a weekly basis, during the May to November growing season, among five 300..., , # Data from: Mast seeding in European beech (Fagus sylvatica L.) is associated with reduced fungal sporocarp production and community diversity

Dataset includes fungal census data, environmental data, beech seed production data, and fungal species trait data.

## Description of the data and file structure

Four files containing relevant data are included.

The first to be called in the code is environmental dataset (\"env.csv\"), which contains mean annual temperature (meanTemp), precipitation (meanPrecip), and beech seed production data (prod) for 1977–2006.

The second dataset is the fungal census data (\"census.csv\"), which contains sums of weekly counts of fungal species from 1977–2006. Column names are as follows: pl.id is the plot identifier (one of five), spl.id is the subplot identifier (one of three per plot), year.id is year, Species.name is species, count is the number of fruitbodies observed on...

# 数据集概述
本数据集整合了欧洲山毛榉（Fagus sylvatica）的种子生产时间序列数据，与采自拉沙讷真菌保护区（La Chanéaz Fungus Reserve）1977至2006年的真菌普查数据，旨在解析结实大年（mast seeding）与真菌资源可获得性之间的关联。本数据集包含年度真菌物种计数、物种性状、同期气象数据以及种子生产数据，并附带完成数据分析所用的代码。

本次真菌普查在占地75公顷的拉沙讷真菌保护区（La Chanéaz Fungus Reserve）开展，该保护区于1975年设立，位于瑞士佩耶讷（Payerne）附近，由瑞士联邦森林、雪与景观研究所（WSL）负责运营；样地地理坐标为北纬46°47′55″至46°48′10″、东经6°59′52″至7°00′30″（Straatsma等，2001）。

该样地位于瑞士中央高原，为原始森林，平均海拔585米，群落以多层结构的欧洲山毛榉（Fagus sylvatica）为优势种，伴生有云杉（Picea abies）、落叶松（Larix decidua）、夏栎（Quercus robur）、欧洲赤松（Pinus sylvestris）与北美白松（Pinus strobus）、桐叶槭（Acer pseudoplatanus）以及白蜡树（Fraxinus excelsior），土壤为钙积雏形土（calcaric cambisol）。研究区域以2米高的围栏环绕，以防止采菇者及其他动物采食真菌子实体。

1975至2006年间，研究人员共记录并鉴定了115417个大型真菌（具肉眼可见子实体）的地表子实体（epigeous sporocarps）。调查于每年5月至11月的生长季每周开展一次，在5个300……的样地中进行。
