Abstract Successful production of calves is necessary for growth of North American elk (Cervus elaphus Linnaeus 1758) populations, but few studies have evaluated age-related effects on both the conception and survival of a calf to weaning in multiple free-ranging populations. Conception and survival of calves to weaning were both affected by maternal age, with old (age 9 and older) females showing reproductive senescence as compared to prime-aged (ages 2–8) females despite achieving similar or greater size and condition. Reproductive senescence in our free-ranging populations ultimately resulted in old females weaning fewer calves (0.42 calves/female) than did prime-aged females (0.64 calves/female). Other factors, especially maternal size, also influenced conception and survival to weaning, and these interacted with age in a consistent manner, i.e. larger females or females in better condition were more likely to conceive and successfully wean calves within each age class. Female age structure receives less consideration in ungulate management than does male age structure, despite demonstrated impacts on population productivity of multiple species because of reproductive senescence. Because of the large proportion of individuals in senesced age classes in elk populations, low productivity in populations may simply reflect female age structure, rather than other frequently hypothesized factors.

AbstractAn epidemiological survey of 1688 free-ranging raccoons (Procyon lotor) captured on the Japanese main islands of Hokkaido, Honshu and Kyushu was undertaken to determine whether Baylisascaris procyonis, which provokes fatal neurological larva migrans was present; however, the worm was not detected in any of these individuals. A helminthological investigation was carried out on 229 of the captured racoons and the following worms obtained: Toxocara tanuki, Porrocaecum sp., Molineus legerae, Ancylostoma kushimaense, Aonchotheca putorii, Centrorhynchus sp., Centrorhynchus bazaleticus, C. elongatum, Plagiorhynchidae gen sp., Hemiechinosoma sp., Metagonimus takahashii, M. miyatai, Euparyphium sp., Plagiorchis muris, Brachylaima sp., and Taenia hydatigena. These were the first records of Porrocaecum sp., M. miyatai, Brachylaima sp. and T. hydatigena obtained from Japanese feral raccoons. Scanning electron microscopic and/or molecular analyses were performed for both T. tanuki and T. hydatigena as these helminths both have a zoonotic counterpart amongst their families.

Assessment of body condition of free-ranging animals is important when evaluating population health and fitness. The following study used body condition scoring, ultrasound, and dissected physical measurement to assess fat stores in free-ranging raccoons (Procyon lotor). Measurements were taken of subcutaneous fat at interscapular, thoracolumbar, and lumbosacral paraspinal and ventral midline sites. These measurements were examined in relationship to body condition scores and body weight. The ultrasound technique accurately measured the subcutaneous fat of raccoons when compared to dissected physical measurement and yielded data that strongly correlated with both body condition score and body weight, with the ventral midline measurement most strongly correlated. This noninvasive method may be useful in conjunction with body condition score and body weight when assessing the nutritional status of raccoons and potentially other small carnivore species.
