DRAFTING…<\/em><\/p>\n

Compared to 2011 and earlier visits to Bath (2005, 1994, 1968-70), in 2015, the seagrasses Thalassia testudinum<\/em> and Syringodium filiforme<\/em> were much more sparse and shorter, and the Avarianvilla<\/em>* cover more extensive and more dense, seemingly “choking out” T. testudinum<\/em>; where seagrasses occurred with sparse or no co-occurrence of Avrianvillea<\/em>, there was a lot of erosion and exposure of rhizomes.<\/p>\n

It appeared<\/em> that a successional sequence driven by positive feedback between substrate stability and substrate-stabilizing seagrasses and algae,\u00a0inferred in 1969, was going to completion over a large swaths of the lagoon:<\/p>\n

Loose Substrate–>Colonization by <\/em>S. filiforme-->Colonization by <\/em>T. testudinum–>Exclusion of <\/em>S. filiforme & new colonization by <\/em>Avrainvillea spp–>”Pure” <\/em>Avrainvillea spp (and other alage, corals etc) climax<\/em><\/p><\/blockquote>\n

The climax, “pure” Avrainvillea<\/em> communities seemed to be much more resistant than the seagrass communities to strong wave disturbance; wave disturbance in the lagoon had increased from previous years, attributable to erosion of big\u00a0 emergent rocks in The Platform area, hardscaping of the shoreline and climate change.
\n*“Avrainvillea” at Bath refers to\u00a0two species or species groups: A.rawsonii<\/em> and A. nigricans<\/em><\/small><\/p>\n
