Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. 1. Describe a biophysical template for Flathead Lake based on spatial and temporal habitat heterogeneity. a. Determine joint sampling sites for the study. The lake will be divided into cells (ca. 40) as a way of logically nesting primary habitat descriptors (e.g. substrate, seasonal current patterns, depth, thermal regime, turbidity) which vary spatially.
2. 2. Conduct time-series (2 years) sampling of the food web with sampling regime based on the variability in type of data collected. a. Quantify spatial (sites according to the template in objective 1) and temporal (sampling at least 15 times per year) abundance and size structure of dominant food web components (fishes, M. relicta, zooplankton, phytoplankton (chl a)).
3. Correlate foodweb response variables (objective 2) with the biophysical template (objective 1) to develop inferences about foodweb controls in time and space. a. Conduct multivariate and geostatistical analyses of data collected under objectives 1 and 2.
4. Demonstrate foodweb interactions using spatio-temporal distributions (objectives 1-3) and testing for pairwise coexistence of species by diel cycle, habitat, and season, and through gut analyses. a. Analyze the distribution and consumption patterns of higher trophic linkages: large zooplankton and fish.
5. Perform sensitivity analyses on modeled foodweb interactions to identify transfers of energy that are critical in foodweb structuring a. Model food web interactions, using two models: a) energetics-based foodweb simulator (i.e., top down effects, Beauchamp et al., Utah State University ) and b) nutrient-based ecosystem simulation (i.e., bottom-up effects, Levitan and Hall, FLBS)
. b. Perform sensitivity analyses on both models.
6. Identify and quantify roles of hypothesized strong interacting species in foodweb regulation. a. Use the foodweb and the ecosystem models to explore how M. relicta is affecting foodweb; compare to time series trends observed in the lake.
7. Determine probable response of foodweb to lake trout suppression. a. Use the foodweb and the ecosystem models to demonstrate potential ramifications of suppression of foodweb interactors such as lake trout, lake whitefish and/or Mysis relicta
8. Determine the inherent tertiary production capacity of Flathead Lake under different foodweb configurations, given current nutrient loading. a. Use spatial and temporal responses of the phytoplankton community to nutrient loading (i.e., the long term water quality data base collected continuously by FLBS since 1977) in the ecosystem model to elucidate the likelihood of top down controls.
9. Conduct a retrospective analysis of the structure and function of the historical lake foodweb: prior to fish introductions (<1900) and after non-native fish introductions, but pre-Mysis (1930-1980). a. Collate and examine all historic abundance, distribution, and life history data of native and non-native lake biota in context of the foodweb problem at hand.
10. Put study results into regional context by comparing our understanding of Flathead Lake foodweb with what is known about other lentic food webs in the Columbia Basin. a. Literature review of existing data for lentic systems in Columbia basin, including British Columbia similar to Flathead Lake.
. b. Synthesize and compare understanding of food web dynamics in Flathead Lake to regional lentic food web problems.
11. Based on the empirical and modeled results, develop a limnological and fisheries monitoring protocol that encompasses all relevant trophic levels so that future manipulations of the foodweb in Flathead Lake (e.g. lake trout suppression; native salmonid a. Synthesize data and analyses of this study in a monitoring context for foodweb management.
. b. Conduct consultations with all water quality and fisheries management entities with Flathead Lake mandates.
. c. Conduct sensitivity analyses of selected monitoring variables using both models.

Abstract

Research critical structuring/limiting foodweb interactions where hydroelectric operations and exotic species introductions are causing declines in native fishes in spite of traditional mitigation efforts. Using Flathead Lake, MT as a study system, develop a lake biophysical template based on spatial and temporal habitat heterogeneity to be used in formulating a whole foodweb sampling regime. After sampling the food web for 2 year, correlate foodweb response variables with the biophysical template to develop inferences about foodweb controls in time and space. Demonstrate foodweb interactions using spatio-temporal distributions and gut analyses. Perform sensitivity analyses on modeled foodweb interactions to identify transfers of energy that are critical in foodweb structuring. Identify roles of hypothesized strong interacting species (Mysis relicta, lake trout, lake whitefish). Determine probable response of the foodweb to lake trout suppression. Conduct a retrospective analysis of the structure and function of the historical lake foodweb: prior to fish introductions (<1900) and after non-native fish introductions, but pre-M. relicta (1930-1980) to test the hypothesis that the lake foodweb was largely unaffected by introductions until M. relicta induced strong novel species interactions. Place study results into a regional context by comparing our understanding of Flathead Lake foodweb with what is known about other lentic food webs in the Columbia Basin and disseminate information to downstream regional managers with a regional workshop.
