Influenza Infection Neutralizes the Attractiveness of Male Odour to Female Mice (Mus musculus)Ethology - Tập 104 Số 8 - Trang 685-694 - 1998
Dustin J. Penn, Greg Schneider, Krislea White, Patricia Slev, Wayne K. Potts
AbstractThis study aimed to determine if female house mice, Mus musculus domesticus, are able to assess a male's infection status from odour cues. We collected urine from male mice before, during, and after they were experimentally infected with influenza, a respiratory virus. Females spent more time investigating urine collected from mal...... hiện toàn bộ
Assessment Strategies and the Effects of Fighting Experience on Future Contest Performance in the Green Anole (Anolis carolinensis)Ethology - Tập 118 Số 9 - Trang 821-834 - 2012

AbstractSocial experiences can be useful sources of information for animals charged with making fitness‐related decisions. Fighting experience can alter an animal's perception of its fighting ability possibly leading to changes in future contest decisions, which may increase/decrease their probability of winning future contests. Winner and loser effects have been r...... hiện toàn bộ
Prolonged Parental Feeding in Tool‐Using New Caledonian CrowsEthology - Tập 118 Số 5 - Trang 423-430 - 2012
Gavin R. Hunt, Jennifer C. Holzhaider, Russell D. Gray
AbstractAccording to life‐history theory, the duration of extended parental feeding is determined by the costs and benefits of maximising reproductive success. Therefore, the length of regular parental provisioning should be correlated with the time required for juveniles to acquire the skills that they need to be independent. The relatively few cases of extremely ...... hiện toàn bộ
Socio‐Spatial Relationships in Dairy CowsEthology - Tập 116 Số 1 - Trang 10-23 - 2010
Lorenz Gygax, Gesa Neisen, Beat Wechsler
AbstractFarm animals may serve as models for evaluating social networks in a controlled environment. We used an automated system to track, at fine temporal and spatial resolution (once per minute, ±50 cm) every individual in six herds of dairy cows (Bos taurus). We then analysed the data using social network analyses. Relationships were b...... hiện toàn bộ
The effects of exposure to predators on personality and plasticityEthology - Tập 127 Số 2 - Trang 158-165 - 2021
Amy Bucklaew, Ned A. Dochtermann
AbstractPast experiences are known to affect average behavior but effects on animal personality and plasticity are less well studied. To determine whether experience with predators influences these aspects, we compared the behavior of Gryllodes sigillatus before and after exposure to live predators. We found that emergence from shelter an...... hiện toàn bộ
Environmental Conditions and Intraspecific Interference: Unexpected Effects of Turbidity on Pike (Esox lucius) ForagingEthology - Tập 115 Số 1 - Trang 33-38 - 2009
P. Anders Nilsson, Lene Jacobsen, S. Berg, Christian Skov
AbstractInterference among predators decreases per capita foraging rates and has implications for both community dynamics and top‐down trophic processes. Interference originates from behavioural interactions among foragers, and these behaviours could be affected by environmental conditions. In experiments on pike foraging alone or among conspecifics in different le...... hiện toàn bộ
Sex Differences in Giraffe Feeding Ecology: Energetic and Social ConstraintsEthology - Tập 87 Số 1-2 - Trang 79-89 - 1991
Truman P. Young, Lynne A. Isbell
AbstractSex ratios of giraffe groups differ in different habitats, with open vegetation having female‐biased groups, and tall, thick vegetation having male‐biased groups. On a ranch in south‐central Kenya, we quantified habitat differences of male and female giraffe groups and showed that the preference for open habitats by female groups was limited to groups with ...... hiện toàn bộ
