Biologists have repeatedly rediscovered classical models from physics predicting collision
rates in an ideal gas. These models, and their two‐dimensional analogues, have been used …

We describe a Eulerian–Lagrangian–agent method (ELAM) for mechanistically decoding
and forecasting 3-D movement patterns of individual fish responding to abiotic stimuli. A …

Although sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes have been
studied intensively for more than 70 years, many questions remain about their complex life …

Although encounters between organisms are fundamental to many ecological processes, a
general theory of encounters that accounts for random movements and probabilistic events …

We evaluated the interacting influences of river flows and tides on travel time, routing, and
survival of juvenile late-fall Chinook salmon (Oncorhynchus tshawytscha) migrating through …

The ability to monitor movements of animals using radio-and acoustic-telemetry has made it
possible to observe continuous behavioral processes that determine key life history events …

Survival of juvenile fall‐run Chinook Salmon Oncorhynchus tshawytscha through the San
Joaquin River Delta of California (hereafter,“Delta”) has been low for most estimates since …

The survival of juvenile Chinook Salmon through the lower San Joaquin River and
Sacramento–San Joaquin River Delta in California was estimated using acoustic tags in the …

Background Migrations allow animals to find food resources, rearing habitats, or mates, but
often impose considerable predation risk. Several behavioural strategies may reduce this …

Speed regulations of watercraft in protected areas are designed to reduce lethal collisions
with wildlife but can have economic consequences. We present a quantitative framework for …
