Common buckthorn (Rhamnus cathartica) invasion exacerbates white-tailed deer (Odocoileus virginianus) browsing on native woody plants
收藏资源简介：
Selective feeding by overabundant herbivores can considerably alter plant community composition and structure, often benefiting non-native species. White-tailed deer (Odocoileus virginianus) are a dominant herbivore in North America, known for their preference for native plants over unpalatable invasive species. Common buckthorn (Rhamnus cathartica), a widely invasive shrub, is largely avoided by deer, potentially facilitating its competitive advantage against native plants. This study investigates the interactive effects of buckthorn invasion and deer browsing on native woody plants within a post-industrial urban forest undergoing restoration. Specifically, we employed both a long-term observational tree survey and an experimental shrub study to assess buckthorn impacts on native trees and shrubs, and to investigate whether buckthorn presence intensifies deer browsing. For the tree study, we surveyed ten native tree species planted in areas with varying levels of buckthorn invasion to ..., , # Common buckthorn (*Rhamnus cathartica*) invasion exacerbates white-tailed deer (*Odocoileus virginianus*) browsing on native woody plants Dataset DOI: [10.5061/dryad.wstqjq2zp](10.5061/dryad.wstqjq2zp) ## Description of the data and file structure ### Tree survey #### File: Tree.Dryad.csv Ident = individual line number Spp = tree species * ACRU = *Acer rubrum* * ACSA = *Acer saccharinum* * CAOV = *Carya ovata* * CEOC = *Celtis occidentalis* * JUCI = *Juglans cinerea* * PODE = *Populus deltoides* * PLOC = *Platanus occidentalis* * QUBI = *Quercus bicolor* * SANI = *Salix nigra* * TIAM = *Tilia americana* Unit = Tifft area where planted Shelter = sapling protection type Survey data = when the survey was conducted Status = alive (1) or dead (0) Rating = ordinal health rating * 0 = dead * 1 = least healthy * 2 = less than average health * 3 = average * 4 = more than average * 5 = most healthy Buckthorn_Cover = percent cover 1 m2 circle surround...,
种群过剩的植食动物的选择性取食可显著改变植物群落的组成与结构，且通常会使外来物种获益。白尾鹿（Odocoileus virginianus）是北美地区的优势植食动物，其更偏好取食本土植物，而非适口性较差的入侵物种。普通鼠李（Rhamnus cathartica）作为一种广泛分布的入侵灌木，基本不会被鹿类取食，这可能使其获得相较于本土植物的竞争优势。本研究针对一处正在开展修复工作的后工业化城市森林，探究鼠李入侵与鹿类啃食对本土木本植物的交互影响。具体而言，本研究同时采用长期树木观测调查与灌木控制实验两种方法，一方面评估鼠李对本土乔木与灌木的影响，另一方面探究鼠李的存在是否会加剧鹿类的啃食压力。针对乔木研究，我们对种植于鼠李入侵程度各异区域的10种本土乔木进行了调查，以…… # 普通鼠李（Rhamnus cathartica）入侵加剧白尾鹿（Odocoileus virginianus）对本土木本植物的啃食 数据集DOI：[10.5061/dryad.wstqjq2zp](10.5061/dryad.wstqjq2zp) ## 数据与文件结构说明 ### 乔木调查 #### 文件：Tree.Dryad.csv - Ident：个体行编号 - Spp：乔木物种 * ACRU：红花槭（*Acer rubrum*） * ACSA：银枫（*Acer saccharinum*） * CAOV：大果山核桃（*Carya ovata*） * CEOC：美洲朴（*Celtis occidentalis*） * JUCI：灰胡桃（*Juglans cinerea*） * PODE：美洲杨（*Populus deltoides*） * PLOC：北美悬铃木（*Platanus occidentalis*） * QUBI：二色栎（*Quercus bicolor*） * SANI：黑柳（*Salix nigra*） * TIAM：美洲椴（*Tilia americana*） - Unit：种植所在的蒂夫特（Tifft）区域 - Shelter：幼苗防护类型 - Survey data：调查开展时间 - Status：存活状态（1为存活，0为死亡） - Rating：健康等级（有序分类变量） * 0：死亡 * 1：健康状况最差 * 2：健康状况低于平均水平 * 3：健康状况平均 * 4：健康状况高于平均水平 * 5：健康状况最佳 - Buckthorn_Cover：周围1平方米样方内的鼠李盖度（百分比）
