Gas exchange characteristics of the submerged aquatic Crassulacean acid metabolism plant, Isoetes howellii Gas exchange characteristics of the submerged aquatic Crassulacean acid metabolism plant, Isoetes howellii

The submerged aquatic plant Isoetes howellii Engelmann possesses Crassulacean acid metabolism (CAM) comparable to that known from terrestrial CAM plants. Infrared gas analysis of submerged leaves showed Isoetes was capable of net CO2 uptake in both light and dark. CO2 uptake rates were a function of CO2 levels in the medium. At 2,500 microliters CO2 per liter (gas phase, equivalent to 1...

Hematology of the West Indian manatee (Trichechus manatus) Hematology of the West Indian manatee (Trichechus manatus)

Hemograms on blood obtained from 10 clinically normal West Indian Manatees (Trichechus manatus) were studied. The red cells were large and in lower number than in most terrestrial species. The manatee does not have a neutrophil as is present in most species, but it has a heterophil whose granules stain pink with the Wright-Giemsa stain. The eosinophil has uniform red-staining granules...
