Alternatives to Resilience for Measuring the Responses of Ecological Systems to Perturbations by Neubert, Michael G., Caswell, Hal

“…Resilience is a component of ecological stability; it is assessed as the rate at which perturbations to a stable ecological system decay. The most frequently…”

Invasion speeds in fluctuating environments by Neubert, Michael G., Kot, Mark, Lewis, Mark A.

“…Biological invasions are increasingly frequent and have dramatic ecological and economic consequences. A key to coping with invasive species is our ability to…”

Demography and Dispersal: Calculation and Sensitivity Analysis of Invasion Speed for Structured Populations by Neubert, Michael G., Caswell, Hal

“…A fundamental characteristic of any biological invasion is the speed at which the geographic range of the population expands. This invasion speed is determined…”

When Can Herbivores Slow or Reverse the Spread of an Invading Plant? A Test Case from Mount St. Helens by Fagan, William F., Lewis, Mark, Neubert, Michael G., Aumann, Craig, Apple, Jennifer L., Bishop, John G.

“…Here we study the spatial dynamics of a coinvading consumer‐resource pair. We present a theoretical treatment with extensive empirical data from a long‐studied…”

Body Size and Food Web Structure: Testing the Equiprobability Assumption of the Cascade Model by Neubert, Michael G., Blumenshine, Steven C., Duplisea, Daniel E., Jonsson, Tomas, Rashleigh, Brenda

“…The cascade model successfuly predicts many patterns in reported food webs. A key assumption of this model is the existence of a predetermined trophic…”

Habitat Destruction, Fragmentation, and Disturbance Promote Invasion by Habitat Generalists in a Multispecies Metapopulation by Marvier, Michelle, Kareiva, Peter, Neubert, Michael G.

“…Species invasions are extremely common and are vastly outpacing the ability of resource agencies to address each invasion, one species at a time. Management…”

Marine reserves and optimal harvesting by Neubert, Michael G.

“…Advocates of no‐take marine reserves emphasize their conservation benefits. Critics counter that reserves would decrease fisheries yield. Analysis of a…”

Projecting Rates of Spread for Invasive Species by Neubert, Michael G., Parker, Ingrid M.

“…All else being equal, the faster an invading species spreads, the more dangerous its invasion. The projection of spread rate therefore ought to be a central…”

Demography and Dispersal: Life Table Response Experiments for Invasion Speed by Caswell, Hal, Lensink, Rob, Neubert, Michael G.

“…Long-distance dispersal has many consequences. One of these is the speed with which a population can invade a new habitat. This invasion wave speed can be…”

Chaos and closure terms in plankton food chain models by Caswell, Hal, Neubert, Michael G

“…‘Closure terms’ describe the mortality of top predators in plankton food chain models. Here we present a counter-example to the conjecture that non-linear…”

Fire Increases Invasive Spread of Molinia caerulea Mainly through Changes in Demographic Parameters by Jacquemyn, Hans, Brys, Rein, Neubert, Michael G.

“…We investigated the effects of fire on population growth rate and invasive spread of the perennial tussock grass Molinia caerulea. During the last decades,…”

The subcritical collapse of predator populations in discrete-time predator-prey models by Neubert, M G, Kot, M

“…Many discrete-time predator-prey models possess three equilibria, corresponding to (1) extinction of both species, (2) extinction of the predator and survival…”

Reactivity and transient dynamics of predator–prey and food web models by Neubert, Michael G, Klanjscek, Tin, Caswell, Hal

“…Stability and resilience characterize the asymptotic responses of perturbations to the equilibria of ecological models. Short-term responses, however, can…”

Integrodifference equations, Allee effects, and invasions by Wang, Mei-Hui, Kot, Mark, Neubert, Michael G

“…Models that describe the spread of invading organisms often assume no Allee effect. In contrast, abundant observational data provide evidence for Allee…”

Density-dependent vital rates and their population dynamic consequences by Neubert, M G, Caswell, H C

“…We explore a set of simple, nonlinear, two-stage models that allow us to compare the effects of density dependence on population dynamics among different kinds…”

Dispersal and Pattern Formation in a Discrete-Time Predator-Prey Model by Neubert, M.G., Kot, M., Lewis, M.A.

Stabilizing Dispersal Delays in Predator–Prey Metapopulation Models by Neubert, Michael G., Klepac, Petra, van den Driessche, P.

“…Time delays produced by dispersal are shown to stabilize Lotka–Volterra predator–prey models. The models are formulated as integrodifferential equations that…”
