The role of omnivorous crayfish in littoral communities

NJ Dorn, JM Wojdak - Oecologia, 2004 - Springer
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

SD Peacor, NJ Dorn, JA Smith, NE Peckham… - Ecology …, 2022 - Wiley Online Library
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

MR Pintar, NJ Dorn, JL Kline, JC Trexler - Science of the Total Environment, 2023 - Elsevier
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 …
