The Economics of Fleeing from Predators
- R. Ydenberg, L. Dill
- Economics
- 1986
Publisher Summary The chapter describes a simple economic model that predicts in a qualitative way on how costs (lost feeding opportunity and risk) interact to produce an optimal flight distance from… Expand
Protandrous arrival timing to breeding areas: a review
- Y. E. Morbey, R. Ydenberg
- Biology
- 4 November 2001
Protandry, the earlier arrival of males to breeding areas than females, is a common pattern of sex-biased timing in many animal taxa (e.g. some insects, fish, amphibians, reptiles, birds and… Expand
Neighbours, strangers, and the asymmetric war of attrition
- R. Ydenberg, L. Giraldeau, J. Falls
- Psychology
- Animal Behaviour
- 1 April 1988
Abstract The literature showing that territorial residents generally respond more intensely to an intrusion by a stranger than by a known neighbour is reviewed. The functional basis of this… Expand
Trade-offs, condition dependence and stopover site selection by migrating sandpipers
- R. Ydenberg, R. W. Butler, D. Lank, C. Guglielmo, M. Lemon, N. Wolf
- Biology
- 1 March 2002
Western sandpipers Calidris mauri on southward migration fly over the Gulf of Alaska to the Strait of Georgia, British Columbia, where they stop for a few days to replenish reserves before… Expand
The effect of personality on social foraging: shy barnacle geese scrounge more
- R. Kurvers, H. Prins, S. E. van Wieren, K. van Oers, B. Nolet, R. Ydenberg
- Medicine, Psychology
- Proceedings of the Royal Society B: Biological…
- 22 February 2010
Animals foraging in groups can either search for food themselves (producing) or search for the food discoveries of other individuals (scrounging). Tactic use in producer–scrounger games is partly… Expand
Western sandpipers have altered migration tactics as peregrine falcon populations have recovered
- R. Ydenberg, R. W. Butler, D. Lank, B. Smith, J. Ireland
- Geography, Medicine
- Proceedings of the Royal Society of London…
- 22 June 2004
The presence of top predators can affect prey behaviour, morphology and life history, and thereby can produce indirect population consequences greater and further reaching than direct depredation… Expand
Effects of Predation Danger on Migration Strategies of Sandpipers
- D. Lank, R. W. Butler, J. Ireland, R. Ydenberg
- Geography
- 1 November 2003
We examine the potential selective importance of predation danger on the evolution of migration strategies of arctic-breeding calidrid sandpipers. Adult calidrids truncate parental care for reasons… Expand
Foraging : behavior and ecology
- D. Stephens, J. Brown, R. Ydenberg
- Biology
- 2007
Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to… Expand
The body size−burial depth relationship in the infaunal clam Mya arenaria
- S. Zaklan, R. Ydenberg
- Biology
- 15 July 1997
Larger infaunal organisms tend to be buried more deeply than smaller conspecifics, but the ultimate (natural selection) reasons for this have received little attention. A model to explain this… Expand
Food abundance and territory size in juvenile coho salmon (Oncorhynchus kisutch)
- L. Dill, R. Ydenberg, A. H. Fraser
- Biology
- 1 September 1981
Feeding territory size and potential food abundance were measured simultaneously in a field population of juvenile (40–50 mm) coho salmon. Territory size was inversely related to the density of… Expand
