Domiciles of stipe-boring amphipods on subtidal individuals of the kelp Lessonia berteroana

Stipe-burrowing amphipods construct domiciles in thalli of subtidal individuals of the large kelp Lessonia berteroana in northern-central Chile. Characteristics of the domiciles and the amphipod assemblages inside the domiciles were determined from kelp individuals collected at Playa Blanca in 2011 and 2014. The distribution of domiciles and breakages induced by amphipod burrowing were studied in kelp stipes collected at Playa Blanca in 2017. Morphological characteristics of the kelp, such as average blade and internode biomass (wet weight) were recorded.

在智利北部中部的Lessonia berteroana大型藻类亚潮带个体中，掘穴十足目甲壳类生物构建了栖息地。通过2011年和2014年在Playa Blanca收集的海藻个体，确定了这些栖息地及其内部甲壳类生物群落的特征。2017年在Playa Blanca收集的海藻茎中，研究了由甲壳类生物掘穴引起的栖息地分布和破损情况。此外，记录了海藻的形态学特征，如平均叶片和节间生物量（鲜重）。
