The role of omnivorous crayfish in littoral communities
Large omnivorous predators may play particularly important roles determining the structure
of communities because of their broad diets and simultaneous effects on multiple trophic …

The enigmatic Marmorkrebs (marbled crayfish) is the parthenogenetic form of Procambarus fallax (Hagen, 1870)
P Martin, NJ Dorn, T Kawai, C van der Heiden… - Contributions to …, 2010 - brill.com
A mysterious parthenogenetic cambarid crayfish (the Marmorkrebs) has been spreading
across the globe for the past decade. We compare this crayfish directly to two other cambarids, …

Evaluating active and passive sampling methods to quantify crayfish density in a freshwater wetland
NJ Dorn, R Urgelles, JC Trexler - Journal of the North …, 2005 - journals.uchicago.edu
We evaluated the sampling efficacy of 1-m 2 throw traps (active sampler) and baited minnow
traps (passive sampler) across an experimental density gradient (1, 2, 4, 6, 8, 10, and 15/m …

Crayfish assemblage shifts in a large drought‐prone wetland: the roles of hydrology and competition
NJ Dorn, JC Trexler - Freshwater Biology, 2007 - Wiley Online Library
Faster growing, larger and/or more aggressive crayfish species are predicted to dominate
permanent waterbodies. We tested this prediction using a 9 year dataset for two species of …

A skewed literature: Few studies evaluate the contribution of predation‐risk effects to natural field patterns
A narrative in ecology is that prey modify traits to reduce predation risk, and the trait
modification has costs large enough to cause ensuing demographic, trophic and ecosystem …

Aquatic prey switching and urban foraging by the White Ibis Eudocimus albus are determined by wetland hydrological conditions
NJ Dorn, MI Cook, G Herring, RA Boyle, J Nelson… - Ibis, 2011 - Wiley Online Library
Prey availability is known to limit reproduction of some species of nesting birds, but identifying
the primary prey types of a species with a flexible diet can be challenging. For the White …

Hydrological disturbance diminishes predator control in wetlands
NJ Dorn, MI Cook - Ecology, 2015 - Wiley Online Library
Effects of predators on prey populations can be especially strong in aquatic ecosystems, but
disturbances may mediate the strength of predator limitation and even allow outbreaks of …

Resistance of crayfish (Procambarus spp.) populations to wetland drying depends on species and substrate
NJ Dorn, JC Volin - Journal of the North American …, 2009 - journals.uchicago.edu
Wetland or stream drying can be a severe disturbance for aquatic animals, but the severity
of a drying disturbance is context dependent. We used a controlled drying experiment to …

Colonization and reproduction of large macroinvertebrates are enhanced by drought-related fish reductions
NJ Dorn - Hydrobiologia, 2008 - Springer
Aquatic predators and habitat permanence can jointly affect benthic invertebrate biomass and
community composition. In 2006 I sampled fish and invertebrates in ten ponds embedded …

Hydrology-mediated ecological function of a large wetland threatened by an invasive predator
Invasive species are one of the greatest threats to ecosystems, disrupting ecosystem function
and leading to the collapse and extinction of native species. While populations of native …
