如果气候条件变得不适合，气候变化不仅会增加入侵风险，还可能降低入侵植物的竞争力。使用生物气候包络模型，我们表明，气候变化可能会导致在美国西部的五个广泛和占主导地位的入侵植物的范围扩大和收缩。黄星蓟（Centaurea solstitialis）和柽柳（Tamarix spp.）可能会随着气候变化而扩大。Cheatgrass（Bromus tectorum）和斑点矢车菊（Centaurea biebersteinii）可能会在范围内移动，导致扩张和收缩。叶大戟（Euphorbia esula）可能会收缩。曾经难以对付的入侵物种的撤退可能会在数百万公顷的土地上创造恢复的机会。在入侵物种密集的地方识别和建立本地或新物种将对生态学家和土地管理者构成相当大的挑战。必须在其他不受欢迎的物种入侵并消除恢复机会之前解决这一挑战。
Rather than simply enhancing invasion risk, climate change may also reduce invasive plant competitiveness if conditions become climatically unsuitable. Using bioclimatic envelope modeling, we show that climate change could result in both range expansion and contraction for five widespread and dominant invasive plants in the western United States. Yellow starthistle (Centaurea solstitialis) and tamarisk (Tamarix spp.) are likely to expand with climate change. Cheatgrass (Bromus tectorum) and spotted knapweed (Centaurea biebersteinii) are likely to shift in range, leading to both expansion and contraction. Leafy spurge (Euphorbia esula) is likely to contract. The retreat of once-intractable invasive species could create restoration opportunities across millions of hectares. Identifying and establishing native or novel species in places where invasive species contract will pose a considerable challenge for ecologists and land managers. This challenge must be addressed before other undesirable species invade and eliminate restoration opportunities.
