At many beaver (Castor canadensis) sites at Allegany State Park in New York State, red maple (Acer rubrum) is the only or one of the few tree species left standing at the ponds' edges. The relative palatability of red maple (RM) was studied in three ways. (1) At seven beaver sites, the available and utilized trees were recorded and an electivity index (E) computed. Of 15 tree species, RM ranked second or fourth lowest. (2) In experiment I, RM, sugar maple (A. saccharum, SM), and quaking aspen… 
Manipulating Beaver (Castor canadensis) Feeding Responses to Invasive Tamarisk (Tamarix spp.)
TLDR
It is suggested that casein hydrolysate treatment of desirable riparian plant species such as Salix and Populus may promote beaver foraging of invasive tamarisk.
Food Processing by Animals: do Beavers Leach Tree Bark to Improve Palatability?
TLDR
It is concluded that beavers can use water to leach undesirable compounds from their food by leaching out undesirable compounds by means of soaking, in a first of its kind study.
Beaver Loggers: Beaver Herbivory Alters Forest Structure
TLDR
Two studies at Kabetogama and Duluth, Minnesota confirmed beavers’ preference for trembling aspen, Populus tremuloides, and analyzed several boreal tree species for secondary metabolites that might make them unpalatable to beavers.
Forage Preferences of the European Beaver Castor fiber: Implications for Re-introduction
TLDR
The results showed that the reintroduced beavers were highly selective in relation to both the species and the size of the trees they used, however, they selected similar size classes between the preferred tree species, and did not utilise human timber.
Beaver (Castor canadensis) Impacts on Herbaceous and Woody Vegetation in Southeastern Georgia
Abstract North American beavers alter habitat properties such as stream flow, faunal composition and plant community structure. In North America, the majority of studies on impacts by beavers have
Ethyl m-Digallate from Red Maple, Acer rubrum L., as the Major Resistance Factor to Forest Tent Caterpillar, Malacosoma disstria Hbn.
TLDR
HPLC analysis indicated that ethyl m-digallate is present in amounts 10–100 × higher in RME than any other compound, and appears to be the major compound protecting red maple from feeding by FTC, with a minor contribution from other gallates.
Eurasian Beaver (Castor fiber) Winter Foraging Preferences in Northern Poland—The Role of Woody Vegetation Composition and Anthropopression Level
TLDR
Beavers’ foraging preferences, as observed in the study, were similar to those described in the literature and confirmed the role of woody species and their diameters in shaping the beaver’s diet.
Invasive Argentine ants reduce fitness of red maple via a mutualism with an endemic coccid
TLDR
Investigating the effects of a mutualism between the invasive Argentine ant and the endemic terrapin scale on coccid density and the fitness of the host of this mutualism, the endemic red maple, found that red maples with Argentine ants excluded from their canopy had higher seed mass and larger early leaves indicating that this invasive ant-endemic scale mutualism imposed a net fitness cost to the host tree.
Including wildlife habitat in the definition of riparian areas: The beaver (Castor canadensis )a s an umbrella species for riparian obligate animals
TLDR
A review of riparian invertebrates, amphibians, reptiles, mammals, and birds indicates that a 50 m-wide riparian buffer is the mini- mum area for supporting the majority of riparians obligate species, and that riparian buffers be continuous and integrated in a connectivity plan including upland re- serves.

Responses of beaver (Castor canadensis Kuhl) to predator chemicals
TLDR
Free-ranging beaver in two different beaver populations in New York State were exposed to predator chemicals to test feeding inhibition, and predator odors reduced feeding compared to untreated or solvent-treated controls.
Browse selection by beaver: effects on riparian forest composition
TLDR
Intense beaver foraging of trembling aspen decreased tree density and basal area by as much as 43% within ~ 1-ha forage zones surrounding two beaver ponds in northern Minnesota, with long-term implications to forest succession and dynamics.
Food selection by beavers in relation to inducible defenses of Populus tremuloides.
TLDR
It is suggested that quaking aspen is plastic in its defensive chemistry, allocating its resources among various secondary metabolites in response to beaver cutting.
Diet Choice and the Funcional Response of Beavers
TLDR
Investigating the effects of changing sapling availability on foraging se- lectivity and cutting rates by beavers in large experimental enclosures found a slight inflection in the functional response curve for preferred species, which could have a positive effect on trophic interactions.
Optimal central-place foraging by beavers: Tree-size selection in relation to defensive chemicals of quaking aspen
TLDR
Responses to browsing by trees place constraints on the predictive value of standard energy-based optimal foraging models, and limitations on the use of such models are shown.
The effects of beaver in riverbank forest succession
TLDR
A major reduction in density is predicted for future populations of ash, hickory, and hackberry in areas of beaver activity, with a concomitant increase in the density of basswood and elm and possibly silver maple and prickly ash.
Food selection by beavers
TLDR
This technique is applied to a study of selectivity in tree-cutting by two colonies of beavers in central Massachusetts, showing clear preferences in cutting various genera of trees for food yet they cut substantial numbers of trees of non-preferred genera.
Seasonal and year-to-year differences in food selection by beavers
TLDR
Beavers exhibited both seasonal and year-to-year differences in preference for certain genera, which may partly reflect greater seasonal stability in concentrations of stored nutrients in coniferous tree bark than in deciduous tree bark.
Summer Diet Optimization by Beaver
TLDR
Foraging data collected for beaver at Isle Royale National Park, Michigan, during the summer of 1973 provided basic natural history information pertaining to diet, food preferences, rates of consumption and activity cycle consistent with a linear programming model of herbivore optimal foraging.
Use of predator odors as repellents to reduce feeding damage by herbivores
TLDR
The active repellent components of predator odors which suppress deer feeding may be suitable for encapsulation in controlled-release devices which could provide long-term protection for forest and agricultural crops.
