Sleep-related behaviors in zoo-housed giraffes (Giraffa camelopardalis reticulata): Basic characteristics and effects of season and parturition

Despite increasing interest in the behavior of zoo animals, studies of nocturnal behavior of zoo animals are limited. In this study, we investigated the relationship between parturition, season, and the sleep-related behaviors in captive reticulated giraffes to better understand the nocturnal life in giraffes. The subjects were two adult reticulated giraffes living in Kyoto City […]

Characteristics of Cats Admitted to Czech Shelters

The aim of this study was to describe the numbers and characteristics of cats entering Czech shelters. Records of sheltered cats were collected from three cat shelters situated in different regions of the Czech Republic from 2011 to 2015. A total of 2170 cat admissions were analyzed in this study. Significantly (p < .001) greater numbers of […]

Effects of sawdust bedding dry matter on lying behavior of dairy cows: A dose-dependent response

The objective was to determine the effect of sawdust bedding dry matter on the lying behavior of Holstein cows. Dry matter (DM) was varied systematically over 5 treatment levels to test how cows respond to damp bedding. This experiment was repeated during summer and winter to test if the effects of damp bedding varied with […]

Stereotypic Behavior of a Female Asiatic Elephant (Elephas maximus) in a Zoo

This study recorded daytime behavior of a female Asiatic elephant at the Municipal Zoo, Wroclaw, Poland, in both an indoor pen and an outdoor paddock as continuous scan sampling for 140 hr, over 35 days in 1 year. Stereotypic sequences involved bouts of highly repetitive stereotypic movements and much more variable interbout behavior. The study […]

Environmental and social influences on enclosure use and activity patterns of captive sloth bears (Ursus ursinus)

Abstract 10.1002/zoo.1430110607.abs Four adult sloth bears (Ursus ursinus) at the Los Angeles Zoo were studied for 13 months to quantify the influence of environmental and social variables on enclosure use and activity. Observations were conducted in 1-hr samples, using 1-min scans, for a total of 150 hr distributed across two seasons and three time periods. […]

Kangaroo Rats Remodel Burrows in Response to Seasonal Changes in Environmental Conditions

Burrow architecture enhances important animal functions such as food storage, predator avoidance, and thermoregulation. Occupants may be able to maximize fitness by remodeling burrows in response to seasonal changes in climate and predation risk. My objective was to examine how banner-tailed kangaroo rats (Dipodomys spectabilis) modify the number of burrow entrances in response to seasonal […]

Search efficiency of free-ranging plains bison for optimal food items

Optimal decisions in classical foraging models depend on the encounter rate with food items that are often distributed heterogeneously at one or multiple spatial scales. Only a few studies, however, provide a detailed assessment of the determinants of foraging efficiency by free-ranging animals across spatial scales. We evaluated multilevel search efficiency of free-ranging plains bison, […]

Behavioural responses to season and adult sex ratio in the fantail darter Etheostoma flabellare

Social behaviours such as competition for mates, which can indicate the strength and direction of sexual selection, may change either directly or indirectly in response to the operational sex ratio (OSR). Field studies indicate flexibility in social behaviours in response to a changing OSR, in particular as the OSR changes across the breeding season. Remaining […]
