The Market Effect: an Explanation for Pay‐off Asymmetries among Collaborating Animals
Tập 87 Số 1-2 - Trang 97-118 - 1991
Acquired Recognition of Predator Odour in the European Minnow (Phoxinus phoxinus)
Tập 82 Số 3 - Trang 216-223 - 1989
AbstractNaive European minnows (Phoxinus phoxinus) do not show a fright reaction
when they first encounter the odour of a natural predator (the pike: Esox
lucius) or the odour of a non‐piscivorous exotic (tilapia: Tilapia mariae). A
conditioned fright response to both these odours will however develop if minnows
experience them in a potentially dangerous situation, for example, in
conjunction with...
Evolution of Classical Polyandry: Three Steps to Female Emancipation
Tập 111 Số 1 - Trang 1-23 - 2005
(Invited Article)AbstractIn classical polyandry, sex roles are reversed and a
female reproduces with several males, each of whom raises his offspring with
little or no help from her. This mating system occurs in some fishes and birds,
and it is of great interest in relation to parental investment, sex role and
sexual selection theory. The evolution of classical polyandry, however, is
debated and n...
Sex Differences in Giraffe Feeding Ecology: Energetic and Social Constraints
Tập 87 Số 1-2 - Trang 79-89 - 1991
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 young. We suggest that
this diffe...
Orange Spots as a Visual Cue for Female Mate Choice in the Guppy (Poecilia reticulata)
Tập 82 Số 4 - Trang 316-324 - 1989
AbstractPrevious studies have suggested that orange pigment in the color
patterns of male guppies is a cue for female choice. This paper describes a
manipulative experiment designed to test this hypothesis. The color patterns
perceived by females were manipulated by varying the color of light used to
illuminate the experimental aquaria. Orange light dramatically reduces the
conspicuousness of oran...
Influenza Infection Neutralizes the Attractiveness of Male Odour to Female Mice (Mus musculus)
Tập 104 Số 8 - Trang 685-694 - 1998
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 males while they were uninfected than
when they were infected. ...
Decision Making and Assessment in the Fighting Behaviour of Nannacara anomala (Cichlidae, Pisces)
Tập 72 Số 2 - Trang 143-153 - 1986
AbstractPredictions from ESS‐theory concerning assessment of fighting ability
and decision making are tested using a cichlid fish Nannacara anomala. Pairs
with a pronounced difference in weight were allowed to interact. Fight duration
increased when the difference in weight between the contestants decreased and
the probability of an escalation from tail‐beating to mouth‐wrestling also
increased wh...
Undirected Song in Wild Zebra Finch Flocks: Contexts and Effects of Mate Removal
Tập 102 Số 4 - Trang 529-539 - 1996
AbstractWild zebra finches, Taeniopygia guttata, sing frequently throughout the
year but the function of undirected song, the most prevalent type, is unknown.
Paired males commonly sang undirected song in feeding flocks where it occurred
more frequently in the non‐breeding season than in the breeding season. Song
rate varied greatly among males. The context of the singer and the absence of
any ove...
The Payoffs to Producing and Scrounging: What Happens when Patches are Divisible?
Tập 85 Số 2 - Trang 132-146 - 1990
AbstractAlthough many group‐foraging models assume that all individuals search
for and share their food equally, most documented instances of group foraging
exhibit specialized use of producer and scrounger strategies. In addition, many
of the studies have focused on groups with strong individual asymmetries
exploiting food that is not easily divisible. In the present study we describe
individual ...
Socio‐Spatial Relationships in Dairy Cows
Tập 116 Số 1 - Trang 10-23 - 2010
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 based on non‐random attachment and avoidance
relationships in...
