Aniulus Paludicolens, N. SP. (Julida: Paraiulidae), a Bog-Dwelling Milliped

Almost without exception, millipeds require a continuously moist substratum, yet they do not tolerate flooding. Other ecological factors that limit their distribution are subtle and difficult to recognize. Aniulus paludicolens, n. sp., is unique in that all collections are from Sphagnum bogs in the vicinity of the Great Lakes. It is best known from Byron Bog, in southern Ontario. This bog has the following vegetation zones: a, a central bog based on a mat of Sphagnum moss and covered almost entirely by leatherleaf; b, a low wooded region, damp or flooded, with hardwood trees and shrubs at its outer limits and black spruce and larch at its inner limits; and c, wooded slopes occupied by deciduous trees and shrubs. A. psludicolens occurs only in zones b and c, and in greatest numbers in the former. Other millipeds in the bog include A. bollmani Causey, which was collected only in zone c (Judd, 1965). These two species represent the most northern distribution of the genus, of which there are many species in the southern states and Texas. The species most closely related to A. paludicolens is A. pclitus Chamberlin , which occurs in disjunct polytypic populations in the mountain valleys of Arizona, Colorado, and New Mexico

An Evaluation of Max-Flex Fast Fence™ for Reducing Deer Damage to Crops

A 2-year study was undertaken to assess the effectiveness of Max-Flex Fast Fence™ electric fencing materials (polytape) for reducing damage to crops. Specifically, our goal was to look at the efficacy of this product for the home gardener. In the first phase of the project, plots of approximately 1/40 acre were established in areas of historically high deer densities. Each plot was planted with soybeans and randomly assigned to 1 of 4 fencing configurations or to the open control group. Within each plot, 6\u27 wide strips were tilled across the length. These tilled areas were checked for the presence of deer tracks. The study design was replicated 3 times to produce 12 treatment plots (3 of each fence configuration) and 3 open controls. Fences were charged via a New Zealand-type high voltage, low-impedance charger. The open controls were fed on heavily by deer and soon were almost void of foliage. Results suggest that under these conditions even a single strand of polytape 2 1/2\u27 high was successful in preventing deer from entering the plots. Phase 2 of the study used a single strand of polytape 2 1/2\u27 feet from the ground to exclude deer from plots ranging in size from 0.025 acres to 1 acre. Each exclosure was planted with soybeans. Three replication areas were selected and plots randomly established within the replicates. The effectiveness of the single strand was much less conclusive than in Phase I, with deer entering all plots at some time during the study. However, there does appear to be a direct relationship between plot size and number of deer tracks observed in the plot. In addition, there were significant differences in fence effectiveness between replicates. We concluded that a single strand of polytape electric fencing, if properly installed, could be a suitable deterrent to deer in a small garden situation
