Dispersal and Survival of Juvenile Beavers (Castor canadensis) in Southern Illinois

  title={Dispersal and Survival of Juvenile Beavers (Castor canadensis) in Southern Illinois},
  author={Lance B. McNEW, Jr. and Alan David Woolf},
Abstract We used radiotelemetry to estimate natal dispersal patterns and survival rates of 13 yearling and 19 subadult beavers (Castor canadensis) at two geomorphologically different sites in southern Illinois. Overall, we observed a 55% dispersal rate for yearlings and a 73% dispersal rate for subadults. Normally, juveniles (yearlings + subadults) initiated dispersal around 16 February (range = 28 Jan.–20 Mar.) and settled around 18 April, with juveniles remaining transient from late January… 

Demography of Unexploited Beavers in

This research provides information to wildlife managers about beaver demographics for a high-density population, based on relatively large sample sizes and novel research techniques for the species.

Survival, Home Range, and Colony Reproduction of Beavers in East-Central Illinois, an Agricultural Landscape

Survival, habitat factors that affect home range size, and colony reproduction for beavers radio-tagged in east-central Illinois, an intensively farmed region, are examined.

When to leave: the timing of natal dispersal in a large, monogamous rodent, the Eurasian beaver

Conspecific Aggression by Beavers (Castor canadensis) in the Sangamon River Basin in Central Illinois: Correlates with Habitat, Age, Sex and Season

The results suggest both sexes participate in territorial defense through physical confrontations and such encounters can be costly to both dispersing juveniles and resident adults.

Microsatellite analysis of mating and kinship in beavers (Castor canadensis)

In contrast to long-held views that beavers are genetically monogamous and colonies are typically 1st-order relatives, a wide range of relationships among colony members and multiple paternity in >50% of litters are documented.

Why invasive Patagonian beavers thrive in unlikely habitats: a demographic perspective

Understanding the demography of an invasive species is crucial to better guide managers seeking to slow the spread of the invader. Habitat differences can affect demographic rates, which may in turn

Habitat selection of an expanding beaver (Castor fiber) population in central and upper Morava River basin

Habitat selectivity by European beaver (Castor fiber L., 1758) was studied in 226 km of river channels during their colonization of the Morava River basin (the Czech Republic), which had not been

Movement Patterns of Resident and Translocated Beavers at Multiple Spatiotemporal Scales in Desert Rivers

Wildlife translocations alter animal movement behavior, so identifying common movement patterns post-translocation will help set expectations about animal behavior in subsequent efforts. American and

Genetic Population Structure within and Between Beaver (Castor canadensis) Populations in Illinois

Estimates of population subdivision, cluster analysis, and dispersal indicate that these populations are genetically distinct, but are connected by infrequent dispersal.

Effects of spatiotemporal resource heterogeneity on home range size of American beaver

Home range sizes of American beavers increased with increasing total NDVI and proportions of woody plant cover within home ranges probably to avoid overexploitation of Woody plants, and the combination of resource quantity, spatial distribution and seasonal variation of resources influences movements and home ranges of central place foragers.



Dispersal pattern and effective population size of the beaver.

The dispersal pattern of the beaver was studied by intensive livetrapping, tagging, and observation in Allegany State Park and its vicinity in New York from 1984 to 1996, indicating that beavers, especially males, may prefer to disperse to the near - est available sites.

Composition and Demographics of Beaver (Castor canadensis) Colonies in Central Illinois

The size and sex-age composition of beaver colonies in Illinois, the reproductive potential of female beavers in these colonies and the efficacy of night-vision surveys versus removal trapping for estimating colony size were investigated.

Population Parameters and Colony Composition of Beaver (Castor canadensis) in Southeast Ohio

The population dynamics of beaver was studied in SE Ohio from 1974 to 1978 and only one parentprogeny pair bond formed after the over-winter loss of the adult male, however.

Beaver dispersal in western Montana

Data analyses indicated a greater frequency and distance of moves by beavers frcan January to June; artificial dispersers moved more frequently and greater distances than natural dispersers; beavers in areas of low quality habitat moved greater distances more frequently than those of better quality habitat; and male beavers moved greater distance than females.

Movements of Transplanted Beavers in Wisconsin

From 1951 to 1957, 2,200 beavers (Castor canadensis) were livetrapped in north and central Wisconsin, ear-tagged, and moved to new release sites. Recaptures totaled 472. Mean movement distances of

Natural Movements of Beavers in Southeastern Idaho

Of the limited sample, the yearling age-class, and the males of all age groups, showed the greatest migration tendencies, and some beavers have an innate tendency to leave their home colony when about 2 years old, rather than being driven off by their parents.

Behavioral and Ecological Characteristics of A “Climax” Population of Beaver (Castor Canadensis)

The characteristics of an unexploited (unharvested) beaver population in New York State are described and the beavers are adaptable and need little management by humans.

Notes on age at dispersal of beaver (Castor fiber) in an expanding population

The observed plasticity in age at dispersal and parturition indicates that the rate of increase may be greater than expected at the front of expanding beaver populations.

Population dynamics of Newfoundland beaver

The demography of beaver was studied in Newfoundland from 1956 to 1965 and it was concluded that territorial behaviour spaces colonies, dispersing the population within the l...
