不同亚马逊特有地区的鸟类对扩散和生态位过程的反应各不相同

基于生态位和扩散的过程支配着淡水群落，如水生昆虫，影响着它们在环境中的分布和建立。因此，我们旨在研究亚马逊淡水系统中生态位和扩散过程对蜻蜓多样性的相对影响，以及物种扩散功能特征对其经度和纬度范围的影响。我们使用散布-生态位连续指数（DNCI）来检验（i）距离较远的地区是否普遍存在以散布为基础的过程，以及（ii）两个鸟纲亚目是否存在不同的模式；通过应用广义线性模型，我们检验了（iii）亚目中与散布相关的功能特征是否会影响物种的纬度和经度中点。我们发现，较远地区的成对散布-龛连续值较低，主要是鞘翅目，这证实了我们的第一个假设。此外，鞘翅目物种的 "散布-iche Continuum "绝对值也最低，而鹮科物种则受到生态位和散布过程的共同影响，这与我们的第二个假设一致。只有颧翅类的散布功能特征与纵向中点之间存在显著联系，这证实了我们的第三个假设。我们的研究结果表明，颧翅目昆虫普遍存在与扩散相关的过程，这可以用河流等巨大的地理障碍以及它们狭窄的生理和生态耐受性来解释。此外，与扩散相关的特征对鞘翅目昆虫的纵向中点有显著影响，而河流的存在可以解释这种情况。更好地了解物种的普遍预测因素以及它们的扩散能力如何支配其分布具有保护意义。
