Habitat complexity in temperate intertidal rockpools was manipulated to assess its effect on fish assemblage structure. We modified the complexity of the substratum within pools by adding or removing loose rocks. The complexity of the water column within pools was modified by the removal of macro-algae and the addition of artificial algae. We applied 5 treatments to 40 pools in 2 locations on the southeast Australian coast: addition of rocks and algae (+R+A), removal of rocks and algae (–R–A), removal of rocks but addition of algae (–R+A), addition of rocks and removal of algae (+R–A), and unmanipulated control pools (C). …
Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart
Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart
Journal of the Iowa Academy of Science: JIAS
Macroinvertebrate and fish habitat is often degraded as a result of agriculture. Riparian buffer strips are commonly used to counteract the negative effects of agriculture in headwater streams. We assessed the relation of multi-aged riparian buffer strips to in-stream habitat, macroinvertebrate and fish assemblages in an Iowa stream. In-stream habitat, macroinvertebrates, and fish were sampled from two buffered sites and two unbuffered sites, with the greatest substrate, water depth, and velocity heterogeneity occurring in buffered sites. The highest macroinvertebrate richness (11) as well as fish species richness (14), diversity (1.99) and IBI score (37) were found in the site buffered …
