Mangrove Response To Attack By A Root Boring Isopod: Root Repair Versus Architectural Modification, Robert Allen Brooks, Susan S. Bell

The nature of the plant-animal interaction between wood-boring isopods and the red mangrove Rhizophora mangle L. has been controversial, with discussion ranging from the damage caused by the isopod being detrimental to beneficial for the mangroves they attack. Initiation of lateral roots by the mangrove in response to isopod burrowing has been one of the most commonly cited examples as support for the concept of beneficial herbivory. In this study, the possibility of root repair as a response of Rhizophora to burrowing by Sphaeroma terebrans Bate was evaluated. Previously burrowed prop roots were tagged in the field and the fate …

The relationship between a suite of physical and biological factors and drift macroalgal abundance was examined in 12 seagrass sites spanning a distance of over 50 km within Tampa Bay, Florida, USA. Field sampling was conducted in December 1991, and drift algal abundance was determined by recording algal percent cover from 25 quadrants at each site. Additionally, drift macroalgae were collected from gridded plots and dry weight biomass measured. Sediment characteristics and seagrass biomass, shoot density, blade length and percent cover at each site were also determined. Likewise, position of site within Tampa Bay was categorized by spatial coordinates. Step-wise …
