- 环境科学 环境科学
- 生态毒理学 生态毒理学
- 气候变化生物学 气候变化生物学
背景情况:
- 淡水生态系统面临着气候变化驱动的因素,如气温上升和盐度变化等越来越大的压力.
- 了解这些全球变化与其他环境压力因素的综合影响,对于预测生态影响至关重要.
- 现有的研究往往检查单个或双重压力因素的相互作用,仅限于复杂的,多重压力因素的场景.
研究的目的:
- 审查和综合来自对盐度,温度和其他压力因素对淡水生物的相互作用影响的受控小规模实验的发现.
- 确定研究缺口,特别是关于三重压力相互作用和代表性不足的物种.
- 为环境适应和缓解不断变化的淡水系统的战略提供信息.
主要方法:
- 对已发表的文献进行系统审查,重点关注人口,个体或亚个体水平的因数实验.
- 排除中宇宙和现场研究,以保持对受控实验条件的关注.
- 根据分析的压力因素的组合对研究进行分类 (例如,压力因素+盐度,压力因素+温度,三重组合).
主要成果:
- 有限的研究 (156篇出版物) 解决了这些综合效应,大多数研究重点是双重相互作用 (盐度或温度与其他压力因素).
- 温度升高通常会放大其他压力因素的影响,而盐度会引起各种反应,包括协同作用和对抗作用.
- 鱼类 (沙龙形状, Perciformes, Cypriniformes) 和一些类 (Daphnia, Ceriodpahnia) 是研究最多的生物,这表明对其他关键的淡水物种缺乏研究.

Responses to Drought and Flooding
10.6K
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Responses to Heat and Cold Stress
13.3K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Responses to Salt Stress
13.0K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Adaptations that Reduce Water Loss
25.1K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Osmoregulation in Fishes
49.3K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Psychological Responses to Stress
41
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...
