Abstract

Peatlands are subject to increased pressure from environmental and land-use change, particularly in temperate regions such as the US Midwest. Bryophytes dominate the ground cover of peatlands and play a key role in their functioning. Effective management and restoration of degraded peatlands requires good understanding of their bryophyte communities, and how these are shaped by environmental conditions. Furthermore, bryophytes are sensitive indicators of environmental conditions. We monitored microhabitat characteristics (hydrology, hydrochemistry, abundance of vascular vegetation, microtopography) alongside bryophyte community composition in nine kettle hole mires in Ohio (USA). We found that the most important drivers of bryophyte community composition and diversity were water level and hydrochemistry. Sampling locations showing poor fen characteristics (high water level, pH and electrical conductivity) were associated with generalist pleurocarpous mosses (indicator species: Amblystegium serpens) and lower species richness. Where bog conditions prevailed, Sphagnum species dominated, and Sphagnum fallax and the liverwort Cephalozia sp. were indicator species.

Give a brief summary of dataset contents, contextualized in experimental procedures and results.

Description of the data and file structure

This is a freeform section for you to describe how the data are structured and how a potential consumer might use them. Be as descriptive as necessary. Keep in mind that users of your data might be new to the field and unfamiliar with common terminology, metrics, etc.

Describe relationships between data files, missing data codes, other abbreviations used. Be as descriptive as possible.

Code/Software

This is an optional, freeform section for describing any code in your submission and the software used to run it.

Describe any scripts, code, or notebooks (e.g., R, Python, Mathematica, MatLab) as well as the software versions (including loaded packages) that you used to run those files. If your repository contains more than one file whose relationship to other scripts is not obvious, provide information about the workflow that you used to run those scripts and notebooks.

Usage notes

The datasets detail bryophyte surveys carried out in nine kettle hole mires in Ohio (US) during 2017, as well as hydrological, hydrochemical and biotic variables associated with the sampling locations.
