Abstract
COVER PHOTO: This photo, taken on March 19, 2023 by Catherine Hulshof De La Peña, shows the view from an abandoned pasture toward the peak of Volcán Cacao (1650 m above sea level) and its tropical cloud forests, in Sector Cacao, Area de Conservación Guanacaste (ACG), Costa Rica. As described in Walter et al. (https://doi.org/10.1002/ecy.4442), evidence shows that temperature and precipitation regimes are shifting across ACG, leading to upslope migration in some taxa, making this elevational gradient an elevator to extinction. Studies like ours to track the ecotone between lowland seasonal tropical dry forests and upland aseasonal wet and cloud forests help identify biological corridors and point to mechanisms driving changes in forest composition and phenology in response to changes in seasonality. Additional images appear in this issue of the Bulletin's Photo Gallery.
封面图片：这张照片拍摄于2023年3月19日Peña，由Catherine Hulshof De La拍摄，展示了从一个废弃的牧场向Volcán可可峰（海拔1650米）及其热带云雾森林的景色，位于哥斯达黎加Conservación瓜纳卡斯特地区（ACG）的可可区。正如Walter等人（https://doi.org/10.1002/ecy.4442）所描述的那样，有证据表明，温度和降水制度正在ACG中发生变化，导致一些分类群的上坡迁移，使这种海拔梯度成为灭绝的升降机。像我们这样追踪低地季节性热带干林和高地季节性湿林和云雾林之间过渡带的研究有助于确定生物走廊，并指出驱动森林组成和物候变化的机制，以响应季节性变化。其他图片出现在本期公报的图片库中。
