MALES FEMALES benthic limnetic What’s different between the species?

benthic limnetic Limnetic Fish Benthic Fish Size Smaller Larger Shape Slim-bodied Deep-bodied Male breeding color Blue & Red Black

Limnetic Fish Benthic Fish Size Smaller Larger Shape Slim-bodied Deep-bodied Male breeding color Blue & Red Black Prey Plankton Worms & Insects Feeding habitat Open water Lake bottom

Limnetic Fish Benthic Fish Size Smaller Larger Shape Slim-bodied Deep-bodied Male breeding color Blue & Red Black Prey Plankton Worms & Insects Feeding habitat Open water Lake bottom

Limnetic Fish Benthic Fish Size Smaller Larger Shape Slim-bodied Deep-bodied Male breeding color Blue & Red Black Prey Plankton Worms & Insects Feeding habitat Open water Lake bottom

Limnetic Fish Benthic Fish Prey Plankton Worms & Insects Feeding habitat Open water Lake bottom Size Smaller Larger Shape Slim-bodied Deep-bodied Male breeding color Blue & Red Black Breeding habitat Open, Shallow Vegetation, Deeper

Females search for mates in specific habitats -Limnetic females search for limnetic males in open habitat - Benthic females search for benthic males in vegetated habitat

If all the vegetation is lost, what might change? When vegetation is present. . .

Questions: 1) Where will benthic and limnetic males nest? 2) How will benthic and limnetic females find mates if vegetation is missing?

Questions: 1) Where will benthic and limnetic males nest? 2) How will benthic and limnetic females find mates if vegetation is missing?

Where will limnetic males and benthic males build their nests? OPEN VEGETATION OPEN

Where will limnetic males and benthic males build their nests? We predict that benthic males will nest in vegetation and limnetic males will nest in the open OPEN VEGETATION

Where will limnetic males and benthic males build their nests? We predict that benthic males will nest in vegetation and limnetic males will nest in the open OPEN VEGETATION What do you predict? OPEN

Where will limnetic males and benthic males build their nests? We predict that benthic males will nest in vegetation and limnetic males will nest in the open OPEN VEGETATION It turns out that Benthic males are very aggressive. They keep limnetic males from building nests. OPEN
