A test of Darwin’s naturalization conundrum in birds reveals enhanced invasion success in the presence of close relatives

Abstract

Growing concern over the environmental and socioeconomic impact of biological invasions has fueled a surge of interest in identifying and preventing situations where the risk of a species becoming invasive is high

A bird in the hand: Global‐scale morphological trait datasets open new frontiers of ecology, evolution and ecosystem science

“…The relationships between morphological traits and key dimensions of avian ecological niches validates the use of trait divergence in studies of range expansion and invasion success among related species. The results of previous analyses are inconclusive, suggesting that trait similarity may either constrain (Pigot & Tobias, 2013) or promote coexistence (Sol et al, 2022) depending on context. Further exploration of this issue is warranted because trait‐based metrics of niche similarity and dispersal ability (HWI) may help us to predict the extent of future range shifts and overlaps, a key goal of predictive models in macroecology and biogeography (Tobias et al, 2020).…”

Darwin’s naturalization conundrum: an unsolved paradox in invasion ecology

“…通 过构建分子进化树的方法, 在亚速尔群岛 [16] 、南非地 区 [17] 和美国科罗拉多河 [32] 等地区的研究也表明, 入侵 性的外来种与本地种的亲缘距离更远, 进而支持达尔 文归化假说的预测. 但是, 同样通过度量外来种-本地 种谱系距离, 基于美国加州蓟属植物 [18] 、地中海地区 紫菀族植物 [33] 和全球58个地区的鸟类 [34] 的研究却发 现, 近缘本地种的存在促进了外来种的成功入侵, 这支 持了预适应假说的预测. 与此同时, 也有研究证据表 明, 外来种-本地种谱系距离对外来种的归化和入侵没 有显著影响 [35,36] .…”

“…Park等人 [46] 在小尺度(样方尺 度)和大尺度(县级尺度)研究了美国外来和本地植物的 亲缘关系, 发现随着空间尺度增加, 外来种和本地种的 亲缘距离显著减小, 因此在大尺度上更符合预适应假 说的预测. 然而, 也有研究发现相反的结果, 即小尺度 研究结果更符合预适应假说 [34,47] , 而大尺度研究结果 更符合达尔文归化假说, 甚至发现随着空间尺度增加, 外来种和本地种的谱系距离逐渐增加 [16,48,49] . 因此, 空…”

When origin, reproduction ability and diet define the role of birds in invasions

“…Furthermore, the functional and phylogenetic properties of the recipient community (e.g. ecological niche saturation, shared evolutionary history with introduced alien species and relative brain size) are likely to mediate the success of alien species [80,81].…”
