AbstractBy injecting fenitrothion into fluid in leaves of pitcher plants, Sarracenia purpurea L., it was determined that the mosquito, Wyeomyia smithii (Coquillett), and the midge, Metriocnemus knabi (Coquillett), are under some risk from fenitrothion forest sprays at the rate of 210 g AI/ha. Wyeomyia smithii is slightly more susceptible than is M. knabi. Other leaf inhabitants, mites and rotifers, were not affected by initial concentrations of fenitrothion in the fluid (up to 9.6 μg/L) that did affect the mosquito and the midge.

And Function

AbstractNiche construction through interspecific interactions can condition future community states on past ones. However, the extent to which such history dependency can steer communities towards functionally different states remains a subject of active debate. Using bacterial communities collected from wild pitchers of the carnivorous pitcher plant, Sarracenia purpurea, we tested the effects of history on composition and function across communities assembled in synthetic pitcher plant microcosms. We found that the diversity of assembled communities was determined by the diversity of the system at early, pre-assembly stages. Species composition was also contingent on early community states, not only because of differences in the species pool, but also because the same species had different dynamics in different community contexts. Importantly, compositional differences were proportional to differences in function, as profiles of resource use were strongly correlated with composition, despite convergence in respiration rates. Early differences in community structure can thus propagate to mature communities, conditioning their functional repertoire.

Frame Number

The aim of the current research was to find the best plant growth regulators for the multiplication of Sarracenia purpurea. Murashige and Skoog medium (MS) was prepared with macronutrients and micronutrients at 1/3 strength, full strength vitamins, supplemented with 30 g/l sucrose and 5 g/l phytagel and autoclaved. After cooling 0.5 mg\l α-naphthaleneacetic acid (NAA), 5 mg\l 6-benzyladenine (BA) or 0.5 mg\l NAA + 3 mg\l BA were added. Young S. purpurea plants were selected and transferred to media with or without plant growth regulators and cultured for 12 weeks. At the end of this time frame number of roots, root length (cm) and number of shoots were evaluated and differences were analysed by the analysis of variance and interpreted using the Tuckey test. The largest number of roots grew in medium supplemented with 0.5 mg\l NAA but the the absence of plant growth regulators increased their length. The best conditions for shoot multiplication were provided by supplementing 1/3MS with 5 mg\l BA.

Previous Summer

Sarcophagid larvae were occasionally found in pitcher-plant (Sarracenia purpurea L.) leaves from mid-June until early September during 1982–1984, in bogs located at The Pas (53°50′N, 101°15′W) and Patricia Beach (50°25′N, 96°36′W), Manitoba, and Kenora, Ontario (49°47′N, 94°29′W). Larvae were collected primarily from “new” leaves (current year's growth), but also from “old” leaves (leaves from the previous summer which retain water throughout the current season). Only one sarcophagid larva was found per leaf.

Oxygen Concentrations

The aquatic habitat contained within the leaf of the pitcher plant Sarracenia purpurea has a dissolved oxygen concentration consistently in excess of 77% saturation in spite of a high community respiration rate. The oxygen concentration is maintained primarily by diffusion through the wall of the sarcophagus and is not affected by plant photosynthesis. Because of the consistently high oxygen concentrations, the inquiline Metriocnemus knabi is not tolerant of lowered oxygen concentrations as it is adapted to a habitat with a consistently high oxygen concentration.
