Climate change is expected to result in the tropicalization of coastal wetlands in the northern Gulf of Mexico, as warming winters allow tropical mangrove forests to expand their distribution poleward at the expense of temperate salt marshes. Data limitations near mangrove range limits have hindered understanding of the effects of winter temperature extremes on mangrove distribution and structure. Here, we investigated the influence of extreme freeze events on the abundance, height and coverage of black mangroves (Avicennia germinans) near their northern range limit in Louisiana.

极端冻结事件的发生频率控制着路易斯安那州沿海黑红树林（Avicennia Germinans）在其北部范围极限附近的分布和结构。

预计气候变化将导致墨西哥湾北部沿海湿地的热带化，因为冬季的变暖使热带红树林可以向南扩展，其分布以温带盐沼为代价。接近红树林范围极限的数据限制妨碍了对冬季极端温度对红树林分布和结构的影响的理解。在这里，我们调查了极端冰冻事件对路易斯安那州北部范围附近的黑红树林（Avicennia Germinans）的丰度，高度和覆盖率的影响。
