  author={Jacoby Carter and A. Lee Foote and A. Johnson-Randall},
We created a model to study the process in which nutria(Myocastor coypus) feeding activities lead to erosion and loss of marsh area. [] Key Method This model ties together data on nutria population dynamics and feeding behavior from the literature with data from field studies on the phenology ofScirpus americanus andSpartina patens conducted in the Barataria Basin, Louisiana, USA in 1992.
Modeling the spread of invasive nutrias (Myocastor coypus) over Iran
A Model to Predict Dispersion of the Alien Nutria, Myocastor coypus Molina, 1782 (Rodentia), in Northern Iran
Nutria (Myocastor coypus Molina, 1782) is a semi-aquatic rodent with a native geographical range in South America. It was introduced to Iran at the beginning of the 20th century. The Ecological Niche
Habitat Selection by Nutria in a Freshwater Louisiana Marsh
During the colder winter months, Nutria appeared to be selecting areas with plant species that offered structure and protection from the elements as well as areas characterized by thin-mat and floating aquatic species that facilitated access to open water.
Distribution, spread and habitat preferences of nutria (Myocastor coypus) invading the lower Nakdong River, South Korea
The distribution patterns revealed that the spread of nutria from farming sites has mainly proceeded along rivers via tributaries, and important factors associated with the establishment of new populations were food availability, levees with suitable burrow materials, and slow water flow.
– We gathered field data to study the impact of the coypu (myocastor coypus), an alien invasive species on the vegetation of a small coastal wetland of central Italy, studying the local diet
Modelling the distribution of an introduced species: The coypu Myocastor coypus (Mammalia, Rodentia) in Piedmont region, NW Italy
A global coypu control strategy must be based primarily on preventing further introductions, and the results of this study could help to produce future risk assessments.
Effective Management of Invasive Nutria (Myocastor coypus) in the UK and the USA
It is the better to take preventative measures against the natural intrusion in advance from invasive alien species that reduce biodiversity and cause economic loss to humans. If the prevention of
Seasonal feeding habits of coypu ( Myocastor coypus ) in South Korea
Coypus appear to make more use of the heavier nitrogen isotope in hind-leg muscle during winter, presumably associated with muscle tissue metabolism contributing to weight loss, and these higher metabolic requirements together with the decreased availability of aquatic vegetation suggest that baiting near waterways in winter could be an effective method to control invasive coypu populations.
The Nutria in Louisiana: A Current and Historical Perspective
Nutria is an exotic, aquatic rodent that was introduced to Louisiana wetlands during the early 1930s and can make coastal restoration more challenging. From 1960 to 1990, greater than 36-million
Genetic population structure of invasive nutria (Myocastor coypus) in Louisiana, USA: is it sufficient for the development of eradication units?
Assessment of the potential for establishing eradication units for the control of nutria in a severely impacted region of the US, southern Louisiana, using nine microsatellite loci, and systematic sampling from each of eight major watershed basins suggests neither the establishment of locally manageable eradications units, nor the development of biological control agents known for their close association with a single source population will be effective in theControl of Louisiana nutria.


A Simulation Approach to Investigating the Response of a Coypu Population to Climatic Variation
The use of population simulations to explore the effect of various combinations of cold and mild winters on the population of feral coypus in eastern England gives a quantitative assessment of the interaction between control trapping and cold weather and its effect in limiting the population.
Population dynamics and regulation in the coypu Myocastor coypus in central Italy
It is shown that post-recruitment losses play only a minor role in determining population decline and pregnancy failure and new-born losses are cumulatively the most important factor contributing to variation in total mortality, and are positively related to coypu numbers in previous periods.
Nutria influence on a Bog Lake in Northern Pomorze, Poland
The coarse, emergent vegetation, with their decay-resisting debris plays a decisive role in the ageing of shallow water bodies, or lakes overgrown with a choking vegetation mat, and physiological choking of lakes made shallow by external factors is shared by WUNDSCH (1958) who otherwise opposes THIENEMANN'S conception of ageing.
Two experiments in inducing nutria aggregation in unfenced artificial ponds
In its natural range in South America nutria (Myocastor coypus MOLINA) has been known to aggregate in dense colonies, controlling the growth of emerged vegetation and producing a typical habitat (1)
Walker's mammals of the world
From aardwolves and bandicoots to yapoks and zorillas, Ernest P. Walker's Mammals of the World is the most comprehensive-the pre-eminent-reference work on mammals. Now, completely revised and
A pragmatic approach to modeling for wildlife management
The need for wildlife professionals to develop the skills for constructing and using small, focused models on a regular basis is stressed and ideas about how to create a modeling culture in conservation and resource management organizations are suggested.
