All parts of plants of the genus Zigadenus (Liliaceae) contain numerous alkaloids through both vegetative and reproductive periods. The purpose of this note is to report the findings of incidental observations and insect collections made during a sutdy of the ecophysiologiy of Z. nuttallii

The decomposition of autumn shed leaves of hackberry (Celtis occidentalis L.) and elm (Ulmus americana L.) in a gallery forest reach and a grassland reach of Kings Creek was examined by placing 24 artificial leaf packs of each species at the two stream sites. Sampling was done after 24 hours and weekly thereafter for a seven week period. No differences between elm and hackberry leaf decomposition rates were measured. The mean percentage weight loss of elm leaves during the sampling period was 90.3\% of their ash-free dry weight in the gallery forest reach and 88.9\% in the grassland reach. The decay coefficients were - 0.0211 and -0.0199 respectively. Hackberry leaves lost 93.8\% of their ash-free dry weight at both sites (decay coefficient of -0.025). Larvae of the leaf shredding insect, Tipula, were found to influence the decomposition process in the grassland reach but not in the gallery forest reach. The Tipula larvae were estimated to exert their greatest influence on the elm leaves

Studies of eastern forest birds and grassland insects of North America are summarized with respect to their implications for conservation and reserve design. Large tracts (thousands of hectares) are required in both forest and grassland biomes for preservation of landscape heritage and conservation of mammal or bird species. Life history strategies of plant or insect species vary geographically, climatically, and along altitudinal, latitudinal, and longitudinal gradients. Development of insect conservation strategies therefore requires a thorough analysis of these habitat characteristics. Goals catering to insect or plant conservation may thus conflict with strategies designed solely for conservation of birds or mammals. In both grassland and forests, conservation strategies should emphasize 1) acquisition of representative large parcels in each major vegetational region, 2) identification and preservation of endangered species, habitats, or communities not protected in large reserves, and 3) insistence that management strategies of large government-owned multiply used landholdings include conservation of biotic diversity as a major objective

The foliar nitrogen and phosphorus contents of 25 gallery forest trees on the Konza Prairie Research Natural Area were measured 1 month before and immediately after autumnal abscission in 1979. Leaves from five trees each of bur oak (Quercus macrocarpa), chinquapin oak (Q. muhlenbergii), green ash (Fraxinus pensylvanica), hackberry (Celtis occidentalis) and red elm (Ulmus rubra), ranging in diameter from 3-77 cm, were sampled. Total leaf contents varied from 47-219 micrograms nitrogen cm-2 and 4.3-23.8 micrograms phosphorus cm-2. Pre- to postabscission decreases of nitrogen and phosphorus were statisticaly significant in all species except red elm. Mean foliar nitrogen decreases varied from 13.2-54.2\% among species and followed the order, chinquapin oak\> bur oak\> hackberry\> green ash\> red elm. Mean foliar phosphorus decreases varied from 7.9-36.7\% and followed the order, buk oak\> chinquapin oak\> green ash\> hackberry\> red elm. Phosphorus reductions were much lower than reductions reported for other hardwood forests in the United States. This may be a function of the availability of soil phosphorus at the various sites. Tree age and diameter were positively correlated with the magnitude of nitrogen reductions. However, stepwise regression models based on all species combined indicated that age and diameter accounted for little of the variance in nitrogen decreases. The measured reductions in foliar nitrogen and phosphorus were not caused by leaching or insect herbivory, but rather were the result of biologically controlled nutrient resorption
