We did not observe adults during the sampling of other coastal spartinas, smooth cordgrass (S.
bakeri are stem borers known from other spartinas (Stiling & Strong 1984; White et al.
The beetle was found in North Carolina from May to Oct on Spartina patens (Ait.
Also desirable would be to determine whether ant densities on native Spartina species differ from those on the adventive weeping lovegrass and whether stems of these grasses differ in their suitability as nesting sites for pseudomyrmecines.
In southern Florida, both species are less common and patchily distributed, because the subtropical climate promotes the replacement of Spartina marshes by mangroves (Waisel 1972; Duncan 1974).
Salt marshes in southern California and Baja California are widely separated by unsuitable habitats, and within these habitats Spartina grows as a fragmented archipelago of small patches (Zedler 1982, 1993; Zedler et al.
This result was particularly surprising given that Spartina marshes form an approximately one-dimensional ribbon of habitat, the situation in which isolation by distance is expected to be greatest (Slatkin and Maddison 1990; Slatkin 1993).
Variable reproductive output among clones of Spartina alterniflora (Poaceae) invading San Francisco Bay, California: the influence of herbivory, pollination, and establishment site.
Spartina occupies a variety of saltmarsh habitats at both north temperate and subtropical latitudes, and is exposed to significant geographic variation in winter disturbance and tidal inundation (Blum 1968, Kirby and Gosselink 1976, Turner 1976, Denno and Grissell 1979, Zedler et al.
Two species of closely related perennial cordgrass, Spartina alterniflora Lois.
dolus occur sympatrically along much of the Atlantic and Gulf coasts of North America where they feed and develop exclusively on Spartina alterniflora (Denno et al.
At most Pacific coast locations the structure of the Spartina foliosa marsh is not comparable to S.
