Evaluating plant lineage losses and gains in temperate forest understories - data and scripts

## Raw data and code to accompany the research entitled "Plant lineage losses and gains in temperate forest understories" by Padullés Cubino et al. (2023). In preparation. # There are two folders with (1) "data" and (2) "scripts". # The "data" folder contains two additional folders ("Input" and "Output") with CSV files with all the data used for analysis and produced from them. These data files are accompanied by a "metadata.xlsx" file with data descriptions. # The "scripts" folder contains three scripts for the analyses described in the manuscript: # H1_H4_H5_H6_forestreplot.R -> tests for hypotheses 1, 4, and 6. # H2_H3_forestreplot.R -> tests for hypotheses 2 and 3. # node.mean_function_forestreplot.R -> R function necessary to test H2 (load before running the code in "H2_H3_forestreplot.R". # If anything is unclear, please contact the corresponding author for clarification (padullesj@gmail.com).

Data from: Successful recovery of native plants post-invasive removal in forest understories is driven by native community features

Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long-term persistence of healthy forest understories is threatened by the impacts of invasive plants. As a result, a common practice is the removal of the agent of invasion. Despite this, we know little about the success of these practices and lack a comprehensive understanding of what intrinsic and extrinsic factors shape the recovery. In a multi-year field experiment, we investigated (Q1) whether native propagule availability drove native community recovery, (Q2) what the characteristics of successfully recovering communities were, and (Q3) under which environmental conditions recovery rates were faster. After initial removal of invasives, we seeded native species to manipulate assembly history and mimic restoration practices, we also implemented a repeated, vs. once, removal treatment, all in a full-factorial design. We collected data on plant species composition and abundance (i.e., species level percent cover) and on environmental conditions (i.e., light and soil water availability) in the three subsequent summers. Our results show that native community recovery rates were independent of seeding additions or frequency of invasive plant removal. The fastest rates of recovery were associated with high native species richness, native communities with higher values of specific leaf area (SLA), and low drought stress years. Our results suggest that restoration practices post-invasive plant removal should be tailored to enhance natural dispersal, or artificial addition if the resident community is species-poor, of native species with traits compatible with high resource availability, such as species with high SLA. In addition to the importance of the native community characteristics, our results underscore the need for assessing environmental conditions, favoring management practices during years of low drought stress to maximize native community recovery.

Data from: Contrasting impacts of short- and long-term large herbivore exclusion on understory net CO2 exchange in a boreal forest

Across boreal forests, trees are the main living biomass carbon (C) stock, but the understory vegetation can contribute significantly to the C cycling and net forest carbon dioxide (CO2) balance. The patchy understory vegetation which consists of sunlit (i.e., lichen-like) and shaded habitats (i.e., dwarf shrub-like) is often altered by ungulate grazers. Grazers may influence understory CO2 exchange, and consequently, the forest CO2 balance. Grazing affects differently the biomass of slow growing lichens compared to the faster growing mosses and dwarf shrubs, and therefore the effects of grazing on CO2 exchange in the patchy understory vegetation could vary temporally. We studied how excluding grazing for short- and long-term affects the CO2 exchange and vegetation biomass in the understory of an oligotrophic Scots pine forest. We measured growing season (2019, 2020) CO2 exchange across sunlit and shaded habitats inside fences that had excluded large grazers for 0–1 and 25–26 years and in the adjacent grazed area. In addition, we measured the height of understory vegetation. We found that short-term grazer exclusion increased ecosystem CO2 source fluxes only in the shaded habitats. However, long-term exclusion of grazing decreased CO2 net release regardless of the habitat type. Furthermore, grazer exclusion increased moss depth immediately which coincided with an abrupt intensification of CO2 net release. Considering the impacts of grazing over both short- and long-term may help to forecast C fluxes more accurately which may be relevant for informed climate solutions regionally and even on a larger scale.
