REPRODUCTIVE PARAMETERS OF MOOSE DURING POPULATION EXPANSION IN NORTH DAKOTA

open access: yesAlces, 2018
Understanding reproductive parameters of a population is vital to management, especially during periods of population fluctuation. Therefore, our objective was to provide the first estimates of reproductive parameters such as pregnancy rates, litter size,

CONSIDERING WEATHER-ENHANCED TRANSMISSION OF MENINGEAL WORM, PARELAPHOSTRONGYLUS TENUIS, AND MOOSE DECLINES

open access: yesAlces, 2018
The risk of meningeal worm (Parelaphostrongylus tenuis) infection in white-tailed deer (Odocoileus virginianus) and neurologic disease in moose (Alces alces) in eastern North America is influenced largely by the effects of weather on deer density and ...

THE IMPORTANCE OF SALT LICKS AND OTHER SOURCES OF SODIUM IN THE ECOLOGY OF THE USSURI MOOSE (ALCES ALCES CAMELOIDES)

open access: yes, 2002
The most important sources of sodium for moose (Alces alces) in Sikhote–Alin are: (1) freshwater aquatic vegetation (river, lake, and bog); (2) marine water and algae; and (3) sodium–saturated ground waters and soils at salt licks.

MOOSE AND DEER POPULATION TRENDS IN NORTHWESTERN ONTARIO: A CASE HISTORY

open access: yesAlces, 2017
Many interrelated factors contribute to the rise and fall of white-tailed deer (Odocoileus virginianus) and moose (Alces alces) populations in the mixed boreal forests of eastern North America where these species often cohabit.

A STUDY OF ELAPHOSTRONGYLUS ALCES IN AN ISLAND MOOSE POPULATION WITH LOW CALF BODY WEIGHTS

open access: yes, 1995
We studied prevalence of Elaphostrongylus alces (Protosyrongylidae; Nematoda), weights, mandible lengths, and mandible marrow fat in a moose population (Alces alces) at Utö in the Stockholm archipelago from October 1989 to November 1994.

USING SNOW URINE SAMPLES TO ASSESS THE IMPACT OF WINTER TICKS ON MOOSE CALF CONDITION AND SURVIVAL

open access: yesAlces, 2019
Snow urine samples collected in northern New Hampshire, USA were used to measure urea nitrogen (UN) and creatinine (C) content to develop ratios for tracking the nutritional restriction of individual moose (Alces alces) through winter (2014–2017 ...

REDUCED COST OF REPRODUCTION IN MOOSE ALCES ALCES THROUGH HUMAN HARVEST

open access: yes, 2001
In life history theory there is a cost related with all resource allocation. For female moose (Alces alces), the cost of reproduction in terms of survival may be reduced for females if calves, or cows without calves, are selectively hunted during the ...

Susceptibility of winter tick larvae and eggs to entomopathogenic fungi - Beauveria bassiana, Beauveria caledonica, Metarhizium anisopliae, and Scopulariopsis brevicaulis

open access: yesAlces, 2017
An isolate of the soil fungus Scopulariopsis brevicaulis was identified from the surface of female winter ticks (Dermacentor albipictus) collected from recently dead moose (Alces alces) calves in New Hampshire in the northeastern United States.

MORPHOLOGICAL CHANGES OF ORGANS DURING ONTOGENY OF MOOSE (ALCES ALCES) COMPARED TO DOMESTICATED RUMINANTS

open access: yes, 2002
The ontogenesis of body mass, the skeleton, organs of the alimentary tract, and the endocrine system of moose (Alces alces), cattle, sheep, and goats were studied in the Ivanovo region using morphological and ontogenetic methods. We noted that changes in

THE EFFECTS OF SEX, TERRAIN, WILDFIRE, WINTER SEVERITY, AND MATERNAL STATUS ON HABITAT SELECTION BY MOOSE IN NORTH-CENTRAL ALASKA

open access: yesAlces, 2016
Habitat selection is a central component of the ecology of individual animals as it affects body condition, survivorship, and reproductive output. We instrumented male and female moose (Alces alces) in north-central Alaska with GPS radio-collars to ...
