Retreat to refugia: Severe habitat contraction projected for endemic alpine plants of the Olympic Peninsula

Abstract: The Olympic alpine endemics are stranded on ever-shrinking habitat islands. Within a few, isolated thermal refugia, the distribution of micro-topography may be a critical factor in determining long-term survival. The Olympic Mountains and their alpine taxa are a model system for endemics worldwide, illustrating the biogeographic characteristics that underpin vulnerability to climate change.

“…Here, we have taken the first steps to forecast the combined direct and indirect effects of climate change on non‐woody vegetation, focusing instead on a high‐elevation herbaceous species. Our results contribute to the growing body of evidence that many high‐elevation plant species will likely lose the majority of their range by the middle to the end of the century (Dirnböck et al., ; Dullinger et al., ; Forester et al., ; Wershow & DeChaine, ) due to the direct effects of climate change alone, and builds on this body of literature by incorporating the compounding indirect effects of altered fire regimes. While the response of S. austromontana may be representative of other taxa, future studies should investigate multiple alpine species to gain a community level understanding of the direct and indirect effects of climate change.…”

“…Many mountain ranges are rich biodiversity hotspots harbouring endemic species restricted to a single range, or even a single peak (Körner, ; Dirnböck et al., ; Jackson et al., ). As the climate warms, cold‐adapted alpine species must migrate upslope, but such migration is constrained by the elevation and substrate of the summit resulting in diminishing and fragmented populations, and possibly local extinctions (Forester et al., ; Jackson et al., ; Wershow & DeChaine, ).…”

“…关 (Cardinale et al, 2012)。然而, 当前生物多样性正 经历快速丧失, 对其进行合理的管理和保护是21世 纪的迫切需求 (Brubaker et al, 1995;Ceballos et al, 2015)。 制定管理和保护措施首先需要对生物多样性 进行评估。生物多样性包括物种多样性、反映演化 历史的系统发育多样性和反映生态系统功能的功 能多样性等不同维度 (Brum et al, 2017;Nakamura et al, 2020)。 近 年 来, 生态学者意识到传统意义上的物 种多样性将所有物种等同 (Magurran, 2003), 显然忽 视了物种在演化历史和生态功能上的差异 (Mouchet et al, 2010), 因此, 系统发育和功能多样性受到了 极大关注 (Cavender-Bares et al, 2009;Funk et al, 2017;Nakamura et al, 2020)。从不同维度评价生物 多样性不但有助于理解群落构建过程 (Webb et al, 2002;Mouchet et al, 2010)和生物多样性格局形成机 制 (Pavoine & Bonsall, 2011), 而且有助于针对不同 地区制定相应的保护措施 (Brum et al, 2017) (Rahbek et al, 2019), 也是生物多样性研究和保护的 关键区域 (Mittermeier et al, 2011)。高山生态系统 (alpine ecosystem; Körner, 2008)普遍存在于所有大 陆和纬度, 通常具有较高的特有种比例 (张瑞等, 2013), 对气候变化和干扰极为敏感 (刘洋等, 2009), 而且有助于促进物种分化 (Knowles, 2001;He & Jiang, 2014)。据统计, 高山占据了全球陆地(除南极 洲外)总面积的2.64% (约3.56百万km 2 ) (Testolin et al, 2020)。树线是高山生态系统的天然分界线 (Körner et al, 2017)。 然而, 近年来研究者观察到气候变化情 景下树线发生了广泛上移现象 (Baker & Moseley, 2007;Gottfried et al, 2012;Sigdel et al, 2020), 这可 能会对高山生态系统造成很大影响 (Wershow & Dechaine, 2018;Lyons & Kozak, 2020)。因此, 高山 生态系统和树线近年来受到了极大关注。 中国西南的横断山区是全球生物多样性热点 地区之一 (Mittermeier et al, 2011) (Pan et al, 2007) and "China's mammal diversity (2nd edition)" (Jiang et al, 2017). Newer literature was adopted if not congruent.…”

“…Studies on population dynamics are important to unveil species' responses to the environment (Pan et al 2013) and their susceptibility to environmental changes (Wershow and DeChaine 2018), which are crucial to the elaboration of conservation and management plans (Morris and Doak 2002). At the regional scale, climate strongly influences the population dynamics of plants (Levine et al 2008;Olsen et al 2016).…”

“…generalists), whereas species with restrict distribution and low abundance tend to show narrower limits (i.e. specialists; Futuyma and Moreno 1988;Kruckeberg and Rabinowitz 1985;Wershow and DeChaine 2018). Hence, generalists should be less sensitive than specialists to environmental differences.…”
