Coprophagy in leporids and other mammalian herbivores
Leporids are the largest of the reingesting species except for the semi-aquatic Coypu, and reingestion by leporids is certainly the most sophisticated, hence its study is important to understanding of their ecology and biology. Expand
Digestion-constrained optimal foraging in generalist mammalian herbivores
The analysis suggests that diet preference is changeable according to the intensity of the digestion constraint, and a priori ranking of food types is not justified in digestion constrained herbivore foraging. Expand
A management policy for sika deer based on sex-specific hunting
The simulation results suggest that management based on sex-specific hunting is effective to diminish the annual variation in hunting yield and to avoid cases of irruption or threatened population under various sets of uncertain parameter values. Expand
Harvest-based Bayesian estimation of sika deer populations using state-space models
It is able to demonstrate that the harvest-based Bayesian estimation is effective in reducing the observation errors in sika deer populations, but the stage-structured model requires many demographic parameters to be known prior to running the analyses. Expand
Harvest-based estimation of population size for Sika deer on Hokkaido Island, Japan
We devised a new method to estimate game populations using relative population sizes and numbers harvested in a population management program for Sika deer (Cervus nippon) in eastern Hokkaido, Japan.Expand
Hard faeces reingestion and the passage and recycling of large food particles in the Japanese hare (Lepus brachyurus)
Ceci suggere que la reingestion des crottes dures n'a pas pour resultat un recyclage multiple des grosses particules difficiles a digerer, induisant a une inefficacite de the digestion. Expand
A Technique to Estimate the Approximate Size of Photographed Bats
A technique to estimate the approximate size of bats using their shadows is developed, which gives unbiased size estimates, but its precision depends on the accuracy of parameters used (camera-position parameters and on-film measurements). Expand
Evaluation of relative density indices for sika deer in eastern Hokkaido, Japan
We evaluated relative density indices of sika deer (Cervus nippon) to aid in population management. We monitored sika deer population trends from 1992 to 2002 in the eastern part of Hokkaido Island,Expand
Supplement: coprophagy in leporids and other mammalian herbivores
The described sequence of reingestion behaviour in the Capybara is also similar to that in leporids and other reingesting herbivores, and the description indicates that the two types of faeces are both nutritionally and morphologically differentiated, hence they are what I have referred to as soft and hard faes in my review.

Coprophagy in the Japanese hare (Lepus brachyurus): reingestion of all the hard and soft faeces during the daytime stay in the form
The daily rhythms of formation and reingestion of hard and soft faeces were studied in Lepus brachyurus, showing that the Japanese hare also reingests a substantial amount of hard faece, and evidence in literature indicates that other Leporidae also practise reingestepping. Expand
