São apresentadas medidas do "standing-crop" e do peso de Spartina alterniflora em um "salt-marsh" de Cananéia. O "standing-crop" foi de 816 ± 187 g de peso seco/m-2 ou 699 ± 164 g peso orgânico/m-2 no pico da estação de crescimento. Em uma área desnudada, o crescimento máximo observado ocorreu em julho, quando a Spartina atingiu 130 cm. A primavera, o verão e o inverno foram, respectivamente, o inicio, o pico e o fim da estação de crescimento. Cinzas, Mg, Ca e Fe tiveram concentração maior em Spartina morta do que nas vivas.

Throw Trap

It is unclear how urbanization affects secondary biological production in estuaries in the southeastern USA. We estimated production of larval/juvenile Fundulus heteroclitus in salt marsh areas of North Carolina tidal creeks and tested for factors influencing production. F. heteroclitus were collected with a throw trap in salt marshes of 5 creeks subjected to a range of urbanization intensities. Multiple factor analysis (MFA) was used to reduce dimensionality of habitat and urbanization effects in the creeks and their watersheds. Production was then related to the first 2 dimensions of the MFA, month, and year. Lastly, we determined the relationship between creek-wide larval/juvenile production and abundance from spring and abundance of adults from autumn of the same year. Production in marsh (g m-2 d-1) varied between years and was negatively related to the MFA dimension that indexed salt marsh; higher rates of production were related to creeks with higher percentages of marsh. An asymptotic relationship was found between abundance of adults and creek-wide production of larvae/juveniles and an even stronger density-dependent relationship was found between abundance of adults and creek-wide larval/juvenile abundance. Results demonstrate (1) the ability of F. heteroclitus to maintain production within salt marsh in creeks with a lesser percentage of marsh as long as this habitat is not removed altogether and (2) a density-dependent link between age-0 production/abundance and subsequent adult recruitment. Given the relationship between production and marsh area, natural resource agencies should consider impacts of development on production when permitting construction in the southeastern USA.
