Respiration Rates

Respiration of needles and surface fine roots was measured in a north central Florida slash pine (Pinuselliottii Engelm. var. elliottii) plantation. A controlled temperature chamber system was used to estimate respiration rates and Q10 values of insitu tissues over a range of 10 to 35 °C. Respiration rates did not differ significantly among seasons, fertilized versus unfertilized plots, or time of day in a diurnal time series (needles). Needle respiration from the lower canopy was less than that from the upper canopy. Fine root respiration measurements were consistent with previously made estimates based on soil CO2 partitioning and trenched plots.

Abstract This study examined the effects of supplemental nitrogen (N) applied to slash pine (Pinus elliottii var. elliottii [Engelm.]) seedlings in a north central Florida nursery. Treatments were applied during a 4 wk period during November and December, 1989, as follows: control (no fall fertilization—current nursery practice); low N (one application of NH4NO3 at 57 kg N/ha); and high N (three applications at the same rate). At time of lifting and outplanting, there were no significant morphological differences among the treatments, but foliar N concentration increased significantly in accord with treatment. Field performance was evaluated at five site-prepared locations. First-year survival of high N and low N treatments were 15 and 12% greater, respectively, than unfertilized seedlings. First-year heights of the high and low N treatments were 15 and 7% greater, respectively, than the control. South. J. Appl. For. 22(2):111-116.

Spiders and their webs are predictable sources of insect cadavers. A small number of animals regularly exploit this resource, either as kleptoparasites or commensals, depending on whether symbionts compete for the same prey (see Robinson and Robinson, 1977, for more detailed terminology). Among the thieves are specialized spiders (citations in Vollrath 1979a, 1979b), mature male and juvenile spiders (Stowe 1978, citations in Nyffeler and Benz 1980), Hemiptera (Davis and Russell 1969), a hummingbird (takes webbing in addition to small insects, Young 1971), panorpid scorpion-flies (Thornhill 1975), Lepidoptera larvae (Robinson 1978), wasps (Jeanne 1972), damselflies (Vollrath 1977), and a handful of flies (reviews in Knab 1915; Bristowe 1931, 1941; Lindner 1937; Richards 1953; Robinson and Robinson 1977). Only a few of the reports on Diptera kleptoparasites originate from North America (McCook 1889, Frost 1913, Downes and Smith 1969). With a single exception (Downes and Smith 1969), all of the previously described kleptoparasitic flies belong to the Brachycera and Cyclorrhapha. We report here on a surprisingly diverse kleptoparasitic Diptera fauna in north central Florida with a cecidomyiid (Nematocera) as its dominant member.

The Way

Ògún, the Yorùbá god of iron, is venerated throughout the Atlantic world. While many African-based religions coexist in Florida, the shrines discussed here were developed by individuals connected with Oyotunji Village in South Carolina. South Florida's urban shrines differ remarkably from north central Florida's rural shrines. I suggest several factors determine this variation: changing characteristics of Ògún, differing circumstances of the shrines' creators, the environment in which the owners work, and whether the setting is urban or rural. Urban shrines reflect religious competition where many manifestations of òrìṣà worship coexist but are not in agreement. In these shrines, Ògún is vengeful protector. The urban shrines tend to be visually strident, filled with jagged forms of protective weapons. In rural north central Florida, Ògún is clearer of the way, a builder, and reflects the personalities of those who venerate him. These shrines are less harsh and are filled with tools.
