c.) are affected by Earth's global climate change. Consequently, researchers are interested in recognizing the effects of this phenomenon on forest ecology and specifically how certain species are adapted to this change. A study conducted by ecologists Jacques Tardif and Yves Bergeron in Quebec's southwestern boreal forests focused on the ecological implications of flood disturbances on populations of black ash (Fraxinus nigra).

Study plots were designated around Lake Duparquet in Quebec to witness the effects of flooding on black ash populations surrounding the lake. Both natural and gradual fluctuations in spring flood levels have enabled black ash populations to adapt to their changing environment. Researchers observed that population stability was due to the strategically different reproduction methods between trees located within the floodplain and trees located in higher elevations. Near the lake, trees relied mainly on vegetative sprouting while less exposed trees away from the lake relied mainly on seed dispersion and germination. Researchers conclude that it is this unique adaptation of black ash to rely on two types of reproduction that characterizes its resilience to flooding disturbance. This reliance may be the trees' natural insurance against the increasing levels of stress influenced by global climate change. But researchers warn that this insurance may only be effective in large stands; smaller groups of trees may not contain the same characteristics and may be more vulnerable to floods.

Exotic Plant Species Invade Hot Spots of Native Plant Diversity
Researchers in Colorado have conducted long term studies on the patterns of exotic plant invasions that have recently challenged some of ecology's existing paradigms. It has been widely hypothesized that diversity begets stability. Areas of low diversity were thought to be less complex systems, while highly diverse areas were considered more complex and thus more efficient in usi
