Costs of learning: the dynamics of mixed-prey exploitation by silver perch, Bidyanus bidyanus (Mitchell, 1838)

K Warburton, C Thomson - Animal Behaviour, 2006 - Elsevier
Although generalist predators have been reported to forage less efficiently than specialists,
there is little information on the extent to which learning can improve the efficiency of mixed …

Learning of foraging skills by fish

K Warburton - Fish and Fisheries, 2003 - Wiley Online Library
This chapter outlines the relationships between a number of key factors that influence
learning and memory, and illustrates them by reference to studies on the foraging behaviour …

Learning to hunt: the role of experience in predator success

A Reid, F Seebacher, A Ward - Behaviour, 2010 - brill.com
Animal behaviour is a composite of innate and learned components. During their lifetimes,
animals typically gain experience and manifest learning, thereby augmenting or modifying …

Optimizing foraging behaviour through learning

RN Hughes, MJ Kaiser, PA Mackney… - Journal of Fish …, 1992 - Wiley Online Library
Manifestation of life‐history strategy is through the allocation of resources acquired by
foraging. Foraging efficiency can be improved by learning, as fishes adjust their behaviour to …

Optimal foraging: the difficulty of exploiting different feeding strategies simultaneously

L Persson - Oecologia, 1985 - Springer
The foraging efficiency of a visually feeding fish, perch (Perca fluviatilis) was studied on two
prey species (Daphnia magna and Chaoborus obscuripus) presented either separately or …

Optimal foraging and habitat shift in perch (Perca fluviatilis) in a resource gradient

L Persson, LA Greenberg - Ecology, 1990 - Wiley Online Library
To better understand how and why foraging shifts between habitats and among prey occur,
and to evaluate the ability of an optimal foraging model to predict diet breadth quantitatively …

Generalists as sequential specialists: diets and prey switching in juvenile silver perch

K Warburton, S Retif, D Hume - Environmental Biology of fishes, 1998 - Springer
Diets of silver perch, Bidyanus bidyanus, in organically fertilised aquaculture ponds were
dominated by chironomid larvae, Daphnia and calanoid copepods. Insects and crustaceans …

AE Quiñones, O Leimar, A Lotem… - The American …, 2020 - journals.uchicago.edu
Learning is an adaptation that allows individuals to respond to environmental stimuli in ways
that improve their reproductive outcomes. The degree of sophistication in learning …

Individual feeding specialisation of a naïve vs. veteran predators

R Knudsen, PA Amundsen… - Ecology of Freshwater …, 2011 - Wiley Online Library
We explored the incidence of individual feeding specialisation among a naïve predator (non‐

Inadvertent errors and error-constrained optimization: fallible foraging by bluegill sunfish

PH Crowley, DR DeVries, A Sih - Behavioral Ecology and Sociobiology, 1990 - Springer
When the expected reward rate is continuously reduced by foraging in a patch, foragers may
adjust their patch persistence times to maximize the average long-term reward rate. The …
