Aquatic Problems Caused by Human Activities in Banff National Park, Alberta, Canada

  title={Aquatic Problems Caused by Human Activities in Banff National Park, Alberta, Canada},
  author={David W. Schindler},
Abstract Despite their protected status, aquatic ecosystems of Banff National Park have been subjected to a number of human stresses. Largely as the result of stocking programs earlier in the century, 10 species of nonnative fishes now occur in the Park, while one endemic subspecies of fish has been extirpated, and 2 other species are threatened. A number of rare invertebrates occur in hot springs and caves, including one mollusk that is endangered. Key invertebrates were extirpated from a… 

Nonchemical Eradication of an Introduced Trout from a Headwater Complex in Banff National Park, Canada

This evaluation evaluated the use of mechanical methods (gill nets and electrofishing) to eliminate a naturalized population of nonnative Brook Trout Salvelinus fontinalis in a subalpine headwater basin.

Why Should We Preserve Fishless High Mountain Lakes

High mountain lakes are originally fishless, although many have had introductions of non-native fish species, predominantly trout, and recently also minnows introduced by fishermen that use them as

Stocked trout do not significantly affect wood frog populations in boreal foothills lakes

Characteristics of the study systems, including the presence of native fish, the length of the anuran larval period, lake trophic status, and the existence of complex, littoral habitats, contributed to the lack of major impacts of stocked trout on wood frog populations.

Improving the Ecological Function of the Upper Bow River: Bow Lake to Kananaskis Dam

The growing population of Canmore, Alberta, Canada and new communities proposed downstream, growing industrialization within the Bow Valley, a changing climate and increasing pressure for water

Impacts of freshwater invaders at different levels of ecological organisation, with emphasis on salmonids and ecosystem consequences

Simultaneous study at several ecological levels should yield a fuller understanding of the mechanisms underlying impacts of invading animals and plants, providing a sounder basis for predicting the impacts of freshwater invasive species.

Complex littoral habitat influences the response of native minnows to stocked trout: evidence from whole-lake comparisons and experimental predator enclosures

The results suggest that complex littoral macrophyte beds provide important refuge habitat for native fishes, which can po- tentially mitigate negative effects associated with introductions of a piscivorous predator.

The Effects of Stocking and Removal of a Nonnative Salmonid on the Plankton of an Alpine Lake

Gill netting is a viable fish eradication technique for smaller (less than 10 ha), shallow ( less than 10 m deep) lakes that lack habitable inflows and outflows or other sensitive species and further work is required to define appropriate removal methods for larger lakes and watersheds.

Assisted colonization of a regionally native predator impacts benthic invertebrates in fishless mountain lakes

The intentional introduction of native cold‐water trout into high‐elevation fishless lakes has been considered a tool to build resilience to climate change (i.e., assisted colonization); however,

Do protected areas benefit freshwater species? A broad‐scale assessment for fish in Australia's Murray–Darling Basin

Summary Assessment of the performance of protected areas in conserving freshwater biodiversity has been limited, has mostly involved small-scale studies and has produced mixed findings. I



Effects of Rotenone on Zooplankton Communities and a Study of their Recovery Patterns in Two Mountain Lakes in Alberta

All crustacean species except one reached prerotenone abundance in about 3 years, probably the minimum time for recovery in these lakes, and Diaptomus sicilis was the last species to recover to its original numbers.

Crustacean Plankton Communities of 340 Lakes and Ponds in and near the National Parks of the Canadian Rocky Mountains

The crustacean plankton communities of 340 lakes and ponds in southern Alberta and southeastern British Columbia were examined and the most frequently occurring and abundant species tolerate a wide range of conditions.

Long-term Invertebrate Community Response to Toxaphene Treatment in Two Lakes: 50-yr Records Reconstructed from Lake Sediments

Analysis of sediment cores from two toxaphene-treated and one untreated lake basin demonstrates both the short-term effect of toxaphene applied in 1961–62 and the longer term effect of subsequent

Geographic distribution, species displacement, and niche overlap for lake trout and bull trout in mountain lakes

The hypothesis that lake trout displace or exclude bull trout from lakes is tested by determining the outcome of introductions of lake trout into two lakes that supported indigenous bull trout.

Crustacean Plankton of 146 Alpine and Subalpine Lakes and Ponds in Western Canada

Investigations of crustacean plankton communities in 146 alpine and subalpine waters in some western Canadian national parks and environs showed that species composition varied little from year to

Fossil pigment records of phytoplankton in trout-stocked Alpine Lakes

Paleolimnology, bioenergetics modelling, and mesocosm experiments were used to quantify changes in phytoplankton following introduction of trout into fishless alpine lakes in the Canadian Rocky

Organochlorine transfer in the food web of subalpine Bow Lake, Banff National Park

The original hypothesis was that unusually high biomagnification via a long food chain was responsible for elevated levels of toxaphene and other persistent organochlorines in the lake trout, but this hypothesis was refuted by the analyses of stable carbon and nitrogen isotope ratios in lake biota.

Historical status of fish populations in Canadian Rocky Mountain lakes inferred from subfossil Chaoborus (Diptera: Chaoboridae) mandibles

Subfossil Chaoborus mandibles preserved in sediments revealed that C. americanus was the predominant species prior to this century in Cabin and Celestine lakes, suggesting that these lakes were originally fishless; C.Americanus (and C. trivittatus in Cabin Lake) were eliminated early this century, contemporarily with the first recorde...

Delayed Deposition of Organochlorine Pesticides at a Temperate Glacier

Many of the organochlorine pesticides that were once widely used have either been banned or uses have been restricted in Canada and the United States. Near areas of high pesticide use at
