Early spring burning of 'Coastal' bermudagrass (Cynodon dactylon (L.) Pers.) sod is a recommended practice for control of the 2-lined spittlebug (Prosopia binincta (say) plant diseases, and winter weeds. This study was designed to determine effects of time of burning on dry matter yields, soil temperature, and forage quality. Coastal bermudagrass sod was burned at 2-week intervals between mid-February and late March for 6 years. When sod was burned about March 1, the average dry-matter yield of Coastal bermudagrass was increased by 1,000 kg/ha over taht of the unburned check plots.
Digestibility and crude protein content of the grass were not affected by burning. Burning, regardless of date, resulted in increased soil temperature at 2.5, 5.0, and 10.0-cm depths. Dry-matter yields were related to soil temperatures, but the relationships appears to be subject to the modifying influences of rainfall, air temperature, and fertility. It is concluded that judicous of Coastal bermudagrass sod is a sound management practice with an added bonus of increased yield in most years. A portable shield for efficient burning of small plots is described. |

Abstract ? On Chichijima, one of the Ogasawara (Bonin) Islands located in the Western Pacific Ocean, land snails have declined, the suggested cause being predation pressure by an invasive flatworm (Platydemus manokwari). Soil fauna were investigated in areas where the snail survives, and where it has become extinct. Much of the fauna, dominated by introduced earthworms and ants, was undiminished, however, one undescribed but endemic carabid (Badister sp.), which selectively feeds on land snails, was absent in snail-extinct areas. The invasive flatworm P. manokwari has been reported to feed also on the carcasses of earthworms, as well as on live snails, and is therefore expected to occur in most parts of Chichijima Island. Among other groups, the density of isopods (also dominated by exotic species) was very low, in comparison with the reported ones 30 years ago. Community structure is currently reflected by dominance of earthworms and ants, decline of endemic isopods, and a high frequency of introduced or alien species. |
