1. Breeding Experience and not Age Modulates the Song Development of Pied Flycatchers (Ficedula hypoleuca)

Author:
Motes‐Rodrigo, Alba; Labra, Antonieta; Lampe, Helene M.
Source:
Ethology 2017 v.123 no.3 pp. 197-204
ISSN:
0179-1613
Subject:
Ficedula hypoleuca; adults; age structure; animal communication; breeding; breeding season; breeding sites; color; learning; males; plumage; probability; songbirds
Abstract:
... In songbirds, the development of the species‐specific adult song involves a learning process that varies in extension. In species that incorporate new song elements throughout life (open‐ended learners), variation in male song composition could be the result of either age or breeding experience. Using data from 16 yr of fieldwork on pied flycatchers (Ficedula hypoleuca), we aimed to disclose the i ...

2. Dual Function of Chip Calls Depending on Changing Call Rate Related to Risk Level in Territorial Pairs of White‐Eared Ground‐Sparrows

Author:

Ethology 2017 v.123 no.3 pp. 188-196
ISSN:
0179-1613
Subject:
Melozone; acoustics; antipredatory behavior; risk; vocalization
Abstract:
... Different mechanisms have been proposed for encoding information into vocalizations: variation of frequency or temporal characteristics, variation in the rate of vocalization production, and use of different vocalization types. We analyze the effect of rate variation on the dual function of chip calls (contact and alarm) produced by White‐eared Ground‐sparrows (Melozone leucotis). We conducted an ...

3. Evidence for Strategic Sex Allocation in the Guppy (Poecilia reticulata): Brood Sex Ratio and Size Predict Subsequent Adult Male Mating Success

Author:
Sato, Aya; Karino, Kenji
Source:
Ethology 2017 v.123 no.3 pp. 221-229
ISSN:
0179-1613
Subject:
Poecilia reticulata; adults; animal behavior; daughters; females; fish; males; reproductive performance; reproductive success; sex allocation; sex ratio; sons
Abstract:
... Sex allocation theory predicts that females should produce more sons when the reproductive success of sons is expected to be high, whereas they should produce more daughters, not daughters when the reproductive success of sons is expected to be low. The guppy (Poecilia reticulata) is a live‐bearing fish, and female guppies are known to produce broods with biased sex ratios. In this study, we exami ...

4. Female Intrasexual Territoriality and its Potential Adaptive Significance: The Pampean Grassland Mouse as an Ecological Model Species

Author:
Bonatto, Florencia; Priotto, José; Coda, José; Steinmann, Andrea R.

Ethology 2017 v.123 no.3 pp. 230-241
ISSN:

Subject:
aggression; breeding; cages; grasslands; home range; lactating females; lactation; mice; models; mothers; nesting; predators; pups; reproductive success; small mammals; territoriality; voles
Abstract:
... Territorial behaviour in female small mammals has been proposed as a mechanism to defend limited ecological resources or their pups against conspecific infanticidal or predators. Female territorial behaviour very often is associated with reproductive activity due to the fact that frequency and intensity of aggression are exhibited mainly when females are pregnant or lactating. In vole and mice spe ...

5. Fitness Costs of Sexual Harassment–The Price of Persuasion

Author:
Jerry, Michelle; Brown, Culum

Ethology 2017 v.123 no.3 pp. 242-250
ISSN:
0179-1613
Subject:
Poecilia reticulata; females; foraging; life history; long term effects; males; mortality; persuasion; progeny; reproductive behavior; reproductive performance; sex ratio; sexual maturity; social behavior
Abstract:
... Females are often subjected to unwanted mating advances from males. Such advances can be costly to both parties. The short‐term costs of harassment to females have been widely explored in the literature; however, few studies have measured the direct fitness costs. Moreover, male costs are seldom considered. Conventional wisdom would lead us to hypothesise that sexual harassment is costly; thus, wh ...

6. Male and Female Soldier Beetles Relax Choice for Mate Quality Across Daily Courtship Periods

Author:
Pratt, Ann E.; Shure, Donald J.; McLain, Denson K.; Banderet, Katrina
Source:
Ethology 2017 v.123 no.3 pp. 175-187
ISSN:
0179-1613
Subject:
Chauliognathus pennsylvanicus; animal behavior; copulation; courtship; females; laboratory experimentation; males; mating frequency; models; reproductive success
Abstract:
... Mutual mate choice occurs when members of each sex will reject some potential mates in efforts to encounter better prospects later. The decision to reject may represent the interaction between mate preferences, mate availability, and temporal constraints. Theory predicts that mutual mate choice will favor relaxed choosiness as mate availability and time for courtship decline. We explored mutual ma ...

7. Scavenging Opportunities Modulate Escape Responses over a Small Geographic Scale

Author:
Fleming, Patricia A.; Bateman, Philip W.

Ethology 2017 v.123 no.3 pp. 205-212
ISSN:

Subject:
Chroicocephalus novaehollandiae; anthropogenic activities; escape behavior; foraging; humans; landscapes; monitoring; opportunity costs; people; predation; prediction; restaurants; risk; scavenging behavior; solid wastes
Abstract:
... Many species that inhabit anthropogenically altered landscapes also opportunistically use human food refuse. Gulls readily exploit anthropogenic food sources (e.g. rubbish dumps and other places of human refuse) and often ‘steal’ food from people eating out of doors. Their behaviour suggests that gulls perceive little risk around people and so we examined whether opportunity costs, that is access ...

8. The Effect of Familiarity with Demonstrators on Social Learning in Three‐Spined Sticklebacks (Gasterosteus aculeatus)

Author:
Trapp, Rebecca M.; Bell, Alison M.

ISSN:

Subject:
Gasterosteus aculeatus; animal behavior; fish; learning; problem solving
Abstract:
... Social learning is an important process in the spread of information, especially in changing environments where inherited behaviors may not remain relevant. In many species, the decision of whom to trust to have reliable information depends on the relationship between individuals. Many fish species, including three‐spined sticklebacks, preferentially associate with familiar individuals. Previous s ...

9. Visual Discrimination of Kin in Mandrills

Subject:
Mandrillus sphinx; animal behavior; animals; experimental design; kin selection; learning; phenotype; photographs
Abstract:
... Phenotype matching, a learning mechanism that evolved based on phenotypic cues shared among relatives, may provide animals with the ability to recognize unfamiliar kin. The generalization of this mechanism across animal species is debated, however, because appropriate tests are difficult to design due to possible confounding effects of familiarity. Hence, only a few studies have examined evidence ...
