— The seasonal food habits of river otter (Lutra canadensis) in beaver swamps in southwest Arkansas were investigated through analysis of 240 scats. Crayfish occurred more frequently in otter scats during winter and spring, and fish occurred more frequently during summer and fall. Silvicultural practices required drainage of beaver swamps during spring, which resulted in rapid changes in water level and loss of otter foraging habitat. An abrupt shift in resource availability is believed to have…

Food habits of a re-introduced river otter (Lontra canadensis) population in Western New York- annual diet, temporal and spatial variation in diet and prey selection conclusions
TLDR
The food habits of this re-introduced population of river otters closely resemble those of previous re- reintroduced populations, and fish and crayfish consumption displayed an inverse seasonal relationship to fish.
Diet of Re-Introduced River Otters, Lontra canadensis, in North-Central Arizona
ABSTRACT Using scat analysis, we studied the diet of a population of river otters (Lontra canadensis) that were re-introduced into the Verde River valley in north-central Arizona. Exotic crayfish
Feeding ecology of the neotropical river otter Lontra longicaudis in an Atlantic Forest stream, south‐eastern Brazil
TLDR
Although they are able to capture mobile prey, otters seem to prefer feeding on prey showing lower escape ability – among fish they select armoured catfish, and among crustaceans they select crabs.
Diet of otters (Lutra lutra) in various habitat types in the Pannonian biogeographical region compared to other regions of Europe
TLDR
Diet composition varied by habitat type and is therefore context dependant, and fish are consumed most frequently in the Atlantic and Boreal, less in the Continental and Pannonian, and least in the Alpine and Mediterranean regions.
Food Habits of the North American River Otter (Lontra canadensis)
Historical records indicate that the North American river otter (Lontra canadensis) occupied most major drainages in the continental United States and Canada at the time of European settlement. By
Seasonal diet of the northern river otter (Lontra canadensis): what drives prey selection?
TLDR
It is concluded that habitat type may be the initial driver of prey selection, while factors such as abundance, agility, and life history of prey may be secondary drivers.
RANGING PATTERNS AND HABITAT UTILIZATION OF NORTHERN RIVER OTTERS, LONTRA CANADENSIS , IN MISSOURI: IMPLICATIONS FOR THE CONSERVATION OF A REINTRODUCED SPECIES
I studied the spacing patterns and habitat utilization by reintroduced northern river otters, Lontra canadensis, at two sites in Missouri because previous studies of otters indicate, plasticity of a
Bioenergetics assessment of fish and crayfish consumption by river otter (Lontra canadensis): integrating prey availability, diet, and field metabolic rate
TLDR
Otter daily energy expenditure is measured with the doubly labeled water method to develop a bioenergetics model for estimating monthly prey consumption and Meek’s crayfish (Orconectes meeki) catch-per-unit-effort was positively related to stream temperature, indicating that cray fish were more available during warmer months.
Characterizing habitat preference of Eurasian river otter (Lutra lutra) in streams using a self-organizing map
We studied the habitat preferences of Eurasian river otters (Lutra lutra) using the distribution patterns of the numbers of spraints and sprainting spots of otters, as well as related environmental
Food Habits and Fish Prey Size Selection of a Newly Colonizing Population of River Otters (Lontra canadensis) in Eastern North Dakota
TLDR
The diet of river otters changed seasonally, including a decline in the frequency of fish in the summer diet, and a corresponding increase in the occurrence of crayfish.

TLDR
Food items were identified in digestive tracts from otters taken by trappers during February, March, and April over a period of 6 years in Wisconsin, Michigan, and Minnesota.

TLDR
Observations of otters fishing and analysis of scats indicated these mammals preyed chiefly on warmwater fishes inhabiting coves, and among invertebrate prey species crayfish were consumed at all seasons and occurred in 56% of the scats.

Seasonal Changes in Coyote Food Habits as Determined by Fecal Analysis
TLDR
The results suggest that coyotes feed opportunistically in Cuyamaca Rancho State Park, California, and seasonal fluctuations in the number of coyotes in relation to corresponding changes in their food habits are examined.
