Connecting microevolutionary processes with macroevolutionary patterns across space and time

Uyeda, Josef C. (2012-10-05)

Whether microevolutionary processes can explain macroevolutionary patterns has long been a matter of contentious debate. The debate has persisted largely because of the challenging task of connecting microevolutionary th ...
Drought, dispersal, and community dynamics in arid-land streams

Bogan, Michael T. (2012-07-10)

Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; ...
Ecological responses to riverine floods and flow alteration

McMullen, Laura E. (2011-07-11)

Floods are major disturbance events for riverine ecosystems, directly and indirectly impacting organisms and their habitat. In this study I investigated the role of riverine floods and flow alteration in regulating aqua ...
Large-scale Flow Experiments for Managing River Systems

Konrad, Christopher P.; Olden, Julian D.; Lytle, David A.; Melis, Theodore S.; Schmidt, John C.; Bray, Erin N.; Freeman, Mary C.; Gido, Keith B.; Hemphill, Nina P.; Kennard, Mark J.; McMullen, Laura E.; Mims, Meryl C.; Pyron, Mark; Robinson, Christopher T.; Williams, John G. (BioOne, 2011-12)

Experimental manipulations of streamflow have been used globally in recent decades to mitigate the impacts of dam operations on river systems. Rivers are challenging subjects for experimentation, because they are open sy ...
Quantifying invertebrate resistance to floods: a global-scale meta-analysis

McMullen, Laura E.; Lytle, David A. (Ecological Society of America, 2012-12-20)

Floods are a key component of the ecology and management of riverine ecosystems around the globe, but it is not clear whether floods have predictable effects on organisms that can allow us to generalize across regions ...
Severe Drought Drives Novel Community Trajectories in Desert Stream Pools

Bogan, Michael T.; Lytle, David A. (Wiley-Blackwell, 2011-10)

1. Ecological communities can be relatively stable for long periods of time, and then, often as a result of disturbance, transition rapidly to a novel state. When communities fail to recover to pre-disturbance configurat ...
