SEASONAL REASSEMBLY OF A RIVER FOOD WEB: FLOODS, DROUGHTS, AND IMPACTS OF FISH
Eighteen years of field observations and five summer field experiments in a coastal California river suggest that hydrologic regimes influence algal blooms and the impacts of fish on algae,
Effects of Disturbance on River Food Webs
A multitrophic model integrating the effects of flooding disturbance and food web interactions in rivers predicted that removing floods would cause increases of predator-resistant grazing insects,
Feeding Ecology of Stream-Dwelling Pacific Giant Salamander Larvae (Dicamptodon tenebrosus)
TLDR
There was considerable dietary overlap among three co-occurring salamander size classes suggesting that food resources were not strongly partitioned among them, and predation on benthic invertebrates by larval Dicamptodon tenebrosus is size selective.
Disturbance and Food Chain Length in Rivers
TLDR
The length of functionally significant food chains is defined as the number of feeding guilds (trophic levels) that are alternately released and suppressed following removal of a top predator, with the criterion that changes in biomass at higher trophic levels must affect biomass of primary producers.
Ecological Comparison between Three Artificial Refuges and the Natural Habitat for Devils Hole Pupfish
TLDR
Physical, chemical, and biological characteristics were compared among the three Devils Hole pupfish refuges and between each refuge and DH and in contrast to the thermally constant environment in DH, mean refuge temperatures were cooler and fluctuated on a weekly and seasonal basis.
Flood disturbance, algal productivity, and interannual variation in food chain length
TLDR
It is suggested that hydrologic regime, rather than productivity, determines the functional length of this river food chain, and that differences among species within trophic levels was crucial in delineating the controlling interactions.
Variation in the Vulnerability of Prey to Different Predators: Community-Level Consequences
TLDR
This work compares the vulnerability of tuft—weaving midges (naked or in algal tufts) to fish and predatory invertebrates, in field and laboratory experiments, and suggests that the vulnerab...
Video as a tool to increase understanding and support for the Endangered Species Act
ABSTRACT Research into the effectiveness of video as a tool to educate students about environmental issues and cause a change in their attitudes toward them in a classroom setting is limited. We
