摘要

在北美东北部冰川覆盖的地区,森林覆盖的春季水池在两栖动物的招募中发挥着不可或缺的作用。在安大略省中南部,春季水池存在于相对未受影响的森林网络中,但两栖动物群落面临着人为引发的气候变化带来的不确定挑战。我们调查了两栖动物幼虫,并从春季水池中收集了栖息地特征的测量值,以收集两栖动物群落结构和物种-栖息地关系的基线信息。两栖动物群落受水周期长度和冠层开放度的影响,早期繁殖两栖动物的相对丰度受池内植被群落结构变化的影响。我们的研究表明,即使在适度的繁殖栖息地特征范围内,两栖动物群落的结构也是动态的。随着人为引发的气候变化导致夏季更加干旱,保护支持不同湿地组合的完整森林将是未来立法的必要组成部分。

Community structure, species–habitat relationships, and conservation of amphibians in forested vernal pools in the Georgian Bay region of Ontario
Forested vernal pools serve an integral role in the recruitment of amphibians in glaciated northeastern North America. In south-central Ontario, vernal pools exist in relatively unimpacted forest networks, but the amphibian communities face uncertain challenges from anthropogenic-induced climate change. We surveyed amphibian larvae and collected measurements of habitat characteristics from vernal pools to collect baseline information on amphibian community structure and species–habitat relationships. Amphibian communities were influenced by hydroperiod length and canopy openness, and the relative abundances of early breeding amphibians were affected by changes in the structure of vegetation communities within pools. Our study suggests that, even across moderate ranges of breeding habitat characteristics, the structure of amphibian communities is dynamic. With anthropogenic-induced climate change leading to more drought-prone summers, the conservation of intact forests that support diverse wetland assemblages will be a necessary component of future legislation.
