Temporal patterns of seed use and availability in a guild of desert ants Temporal patterns of seed use and availability in a guild of desert ants
1 Temporal patterns of seed use were studied from late winter to autumn in three species of seed-harvesting ants in the Sonoran Desert. Measures of effective foraging activity, dietary niche breadth and dietary niche overlaps were obtained each month and were tested for correlation with estimates of the available seed resource.2 Seeds were the only numerically important type of food in...

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...

Lumber spill in central California waters: Implications for oil spills and sea otters Lumber spill in central California waters: Implications for oil spills and sea otters
A large quantity of lumber was spilled in the ocean off central California during the winter of 1978, and it spread through most of the range of the threatened California sea otter population within 4 weeks. The movement rates of lumber were similar to those of oil slicks observed elsewhere. These observations indicate that a major oil spill could expose significant numbers of California...
