Sporobolus cynosuroides (L.) P.M. Peterson & Saarela¼Spartina cynosuroides (L.) Roth is a temperate zone rhizomatous grass that often is a dominant species in coastal brackish marshes on the Gulf coast and Atlantic coasts of the United States where salinity ranges from 0 to 10 psu. Sporobolus cynosuroides (L.) P.M. Peterson & Saarela ¼ Spartina cynosuroides (L.) Roth is usually absent where salinity values are .12 psu. Sporobolus cynosuroides occurs in coastal habitats characterized by infrequent tidal flooding and moderate nutrient levels. Also known as big cordgrass, it may account for net productivity in high marshes that rivals productivity of Sporobolus …

Exploratory field expeditions to the Chocó forests in the northwestern slopes of the Ecuadorian and Colombian Andes resulted in the discovery of two new species of Columnea (Gesneriaceae). Columnea fluidifolia J.L.Clark & F.Tobar, sp. nov., is described as a narrow endemic from Bosque Protector Mashpi and surrounding areas in the province of Pichincha in northern Ecuador. Columnea pendens F.Tobar, J.L.Clark & J.F.Sm., sp. nov., is described from recently discovered populations in the provinces of Carchi and Santo Domingo de los Tsáchilas (Ecuador) and the departments of Cauca and Nariño in southwestern Colombia. The two new species are pendent …
Biological Flora Of The Tropical And Subtropical Intertidal Zone: Literature Review For Rhizophora Mangle L., Hudson R. Deyoe, Robert I. Lonard, Frank W. Judd, Richard Stalter, Ilka Feller
Biological Flora Of The Tropical And Subtropical Intertidal Zone: Literature Review For Rhizophora Mangle L., Hudson R. Deyoe, Robert I. Lonard, Frank W. Judd, Richard Stalter, Ilka Feller

Rhizophora mangle L. is a tropical and subtropical mangrove species that occurs as a dominant tree species in the intertidal zone of low-energy shorelines. Rhizophora mangle plays an important role in coastal zones as habitat for a wide range of organisms of intertidal food webs, as a natural barrier to coastal erosion, and as carbon sequestration. A review of mangrove literature has been performed, but a review specifically on red mangroves has not. The approach was to cover a broad range of topics with a focus on topics that have seen significant work since the 1970s. This review includes a …
Foraging Strategies Are Related To Skull Morphology And Life History Traits Of Melanerpes Woodpeckers, David L. Leonard Jr., Julie A. Heath
Foraging Strategies Are Related To Skull Morphology And Life History Traits Of Melanerpes Woodpeckers, David L. Leonard Jr., Julie A. Heath
Biology Faculty Publications and Presentations
Links between morphology and foraging strategies have been well established for many vertebrate groups. Foraging strategies of Melanerpes woodpeckers are especially variable, with at least six species being proficient flycatchers; the remainder of the better known species do not flycatch. Our objective was to examine variation in foraging tactics as it relates to skull morphology and other life history traits among these species to better understand the biology of these diverse woodpeckers. We measured eight skull characters from 241 individuals representing 19 species, but focused on eight species for which we had the most data. We used the log-geometric mean …
