1. Causes and consequences of avian within-season dispersal decisions in a dynamic grassland environment

Author:
Williams, Emily J.; Boyle, W. Alice
Source:
Animal behaviour 2019 v.155 pp. 77-87
ISSN:
0003-3472
Subject:
Ammodramus savannarum; biogeography; breeding; brood parasitism; case studies; dispersal behavior; grasslands; nests; parents; predation; reproductive success; songbirds; Kansas
Abstract:
... Understanding the causes and consequences of dispersal is key to identifying selective pressures underlying species-level variation in biogeography, metapopulation dynamics and adaptive capacity. We tested the hypotheses that nest predation and/or brood parasitism avoidance drive breeding dispersal decisions and that dispersal functions to reduce subsequent reproductive failure in grasshopper spar ...

2. Loss and re-emergence of plastic ancestral behavioural traits: influences on phenotypic and evolutionary pattern

Author:
Foster, Susan A.; Baker, John A.

Animal behaviour 2019 v.155 pp. 271-277
ISSN:
0003-3472
Subject:
Gasterosteus aculeatus; Pheidole; adaptive radiation; animal behavior; fish; phenotype; phylogeny
Abstract:
... Behavioural phenotypes are notable for their plasticity, in that individual behaviour patterns can be expressed ephemerally in response to an appropriate stimulus and then disappear. In the absence of an appropriate stimulus, behavioural phenotypes can remain unexpressed over many generations, yet the capacity to perform the behaviour can be retained. Here we discuss potential evolutionary influen ...

3. On the importance of individual differences in behavioural skill

Author:
Sih, Andrew; Sinn, David L.; Patricelli, Gail L.

Animal behaviour 2019 v.155 pp. 307-317
ISSN:

Subject:
animal behavior; cognition; courtship; decision making; diet; ecology; food choices; foraging; learning; optimal nutrition; prediction
Abstract:
... A major focus of research in behavioural ecology involves testing whether behaviour, on average, is adaptive. Here, we note that although studies often find that individuals differ in how well they perform adaptive behaviour (e.g. some individuals fit the predictions of optimal diet theory better than others, and some exhibit higher social skill than others), few studies have emphasized these cons ...

4. Rethinking animal social complexity measures with the help of complex systems concepts

Author:
Hobson, Elizabeth A.; Ferdinand, Vanessa; Kolchinsky, Artemy; Garland, Joshua
Source:
Animal behaviour 2019 v.155 pp. 287-296
ISSN:
0003-3472
Subject:
animal behavior; animals; cognition; social behavior; social structure; society
Abstract:
... Explaining how and why some species evolved to have more complex social structures than others has been a long-term goal for many researchers in animal behaviour because it would provide important insight into the links between evolution and ecology, sociality and cognition. However, despite long-standing interest, the evolution of social complexity is still poorly understood. This may be due in p ...
