Influence of microclimate and forest management on bat species faced with global change
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Climate refugia, areas where climate is expected to remain relatively stable, can offer a near‐term safe haven for species sensitive to warming temperatures and drought. Understanding the influence of temperature, moisture, and disturbance on sensitive species is critical during this time of rapid climate change.

, 2001 [中文文摘]从景观破碎、保护历史、种群行为机制和种群大小4个方面讨论了人为干扰对生物多样性的影响,以期为生物多样性保护和生态环境恢复提供依据。一般人为轻度干扰会导致生物多样性提高,对比研究武夷山人为干扰甜槠林与郁闭稳定甜槠林结果表明,人为干扰甜槠林高等植物物种丰富度相对于郁闭稳定林分提高了76.32％;但人为干扰甜槠林的群落优势度却远低于郁闭林,故在演替过程中群落物种多样性的增加是生态系统对外界轻度干扰的一种适应,是恢复生态系统稳定性的一种对策,一旦干扰超过其调节能力,将难以恢复为原来的群落类型 ...

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Protected areas (PAs) are pivotal to biodiversity conservation, yet their efficacy is compromised by insufficient funding and management. So‐called other effective area‐based conservation measures (OECMs) present a paradigm shift and address PA limitations.

Mass mortality of mangroves in Qingmeigang Bay, Sanya—an indication of mangrove fate resulted from accelerated sea-level rise in the future [PDF]
, 2015 在全球变化的各种效应中，海平面的上升是对红树林最大的威胁之一。发生在海南三亚青梅港红树林自然保护区的红树林突发大面积死亡事件作为海岸工程引起红树林淹水时间与深度增加并导致红树林大规模死亡的特例为研究海平面上升对红树林影响提供一个新的角度。未来不断上升的海平面对红树林的破坏作用在此次事件中被间接反映出来。对青梅港红树林死亡事件的调查研究不仅为青梅港地区红树林的恢复、管理提供理论依据，而且对于探讨海平面上升对红树林的影响存在重要意义 ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 3, Page 341-353, May 2024.Abstract Contradictory results in the extant literature suggests that additional risk factors should be considered when exploring the impacts of maternal smartphone use on mother‐infant relationships. This study used cluster analysis to explore whether certain risk factors were implicated in mother‐infant dyads with high smartphone use and low mother ...
