Fluid-dynamic transport and mixing processes affect birth, death, immigration and emigration rates in kelp forests, and can modulate broader community interactions. In the most highly studied canopy-forming kelp, Macrocystis pyrifera (the giant kelp), models of hydrodynamic and oceanographic phenomena influencing spore movement provide bounds on reproduction, quantify patterns of local and regional propagule supply, identify scales of population connectivity, and establish context for agents of early life mortality. Other analyses yield insight into flow-mediated species interactions within kelp forests. In each case, advances emerge from the use of ecomechanical approaches that propagate physical-biological connections at the scale of the individual to higher levels of ecological organization. In systems where physical factors strongly influence population, community or ecosystem properties, such mechanics-based methods promote crucial progress but are just beginning to realize their full potential.
流体力输运和混合过程会影响海藻林的出生、死亡、迁入和迁出率,并能调节更广泛的群落相互作用。在研究最深入的冠层形成海藻中,巨藻(Macrocystis pyrifera)的水动力和海洋现象模型影响孢子运动,为繁殖提供了限制,量化了局部和区域繁殖体供应的模式,确定了种群连通性的尺度,并为早期生命死亡率的因素提供了背景。其他分析还揭示了海藻林中流动介导的物种相互作用。在每种情况下,进展都来自于使用生态力学方法,该方法将个体尺度的物理-生物联系传播到更高的生态组织水平。在物理因素强烈影响种群、群落或生态系统属性的系统中,基于力学的方法促进了至关重要的进展,但才刚刚开始发挥其全部潜力。
