Developing a Metric of Usable Space for Zoo Exhibits
Get PDFThe size of animal exhibits has important effects on their lives and welfare. However, most references to exhibit size only consider floor space and height dimensions, without considering the space afforded by usable features within the exhibit. In this paper, we develop two possible methods for measuring the usable space of zoo exhibits and apply these to a sample exhibit. Having a metric for usable space in place will provide a better reflection of the quality of different exhibits, and enhance comparisons between exhibits

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

The Effect of Early Rearing Experience on Adult Reproductive Behavior in Captive Giant Pandas and Spectacled Bears
No full textThe present study examined the relationship between early rearing experience and reproductive competence in captive adult giant pandas (Ailuropoda melanoleuca) and spectacled bears (Tremarctos ornatus). Life history information of 52 giant pandas and 34 spectacled bears were obtained from the International Studbook and by interviewing staff at institutions housing the subjects. The early rearing experience variables included duration of mother rearing, social access within 1-yr period following maternal separation, and birth origin. Correlation, Chi-square, and logistic regression analyses were used to analyze the data. Contrary to findings from studies with other animals, the results generally suggest that early rearing experience is not related to adult reproductive success in giant pandas and spectacled bears. Alternative explanation and limitation of the study were discussed; suggestions were made for future study.M.S
