Understanding local and geographic factors influencing species distributions is a prerequisite for conservation planning. Our objective in this study was to model local and geographic variability in elevations occupied by native and nonnative trout in the northwestern Great Basin, USA. To this end, we analyzed a large existing data set...
Biological invasions create complex ecological
and societal issues worldwide. Most of the
knowledge about invasions comes only from successful
invaders, but less is known about which processes
determine the differential success of invasions. In this
review, we develop a framework to identify the main
dimensions driving the success and failure...

1. Temperature is a major driver of ecological processes in stream ecosystems, yet the dynamics of
thermal regimes remain poorly described. Most work has focused on relatively simple descriptors
that fail to capture the full range of conditions that characterise thermal regimes of streams across
seasons or throughout the year....
Worldwide, lack of data on stream temperature has motivated the use of regression-based
statistical models to predict stream temperatures based on more widely available data on air
temperatures. Such models have been widely applied to project responses of stream temperatures
under climate change, but the performance of these models has...

Arismendi, I., Safeeq, M., Dunham, J. B., & Johnson, S. L. (2014). Can
Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...

Temperature is a fundamentally important driver of ecosystem processes in streams. Recent warming of terrestrial climates around the globe has motivated concern about consequent increases in stream temperature. More specifically, observed trends of increasing air temperature and declining stream flow are widely believed to result in corresponding increases in stream...
