MULTISCALE GENETIC STRUCTURE OF AN ENDANGERED SEAWEED AHNFELTIOPSIS PUSILLA (RHODOPHYTA): IMPLICATIONS FOR ITS CONSERVATION

Although marine macroalgae have recently entered the lists of endangered species, conservation efforts are still limited by a lack of data, particularly for naturally rare species. One example is the turf-forming Ahnfeltiopsis pusilla (Mont.) P. C. Silva et DeCew. Albeit cataloged as vulnerable in t...

Description
Summary:Although marine macroalgae have recently entered the lists of endangered species, conservation efforts are still limited by a lack of data, particularly for naturally rare species. One example is the turf-forming Ahnfeltiopsis pusilla (Mont.) P. C. Silva et DeCew. Albeit cataloged as vulnerable in the Northwest Iberian Peninsula (NWIP), where it occurs only at five enclaves separated by 1,200 km from the closest recorded presence of the species, nothing is known about its genetic diversity and population connectivity. We used amplified fragment length polymorphism (AFLP) and sequences of the intergenic region between the mitochondrial cytochrome oxidase subunit 2 and subunit 3 genes (cox2-3) to investigate its genetic structure at large (1,200 km), regional (
