Frontiers in Ecology and Evolution, 2022 Foraging animals need to quickly assess the costs and benefits of different foraging decisions, including resource quantity, quality, preference, ease of access, dispersion, distance, and predation risk.

On the Origin of Risk Sensitivity: the Energy Budget Rule Revisited
, 2015 The risk-sensitive foraging theory formulated in terms of the (daily) energy budget rule has been influential in behavioural ecology as well as other disciplines.

Polar Research, 2017 Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While this may reduce herbivore survival,

Investigating Optimal Foraging Theory in the Laboratory
The American Biology Teacher, 2014 Optimal foraging theory is a principle that is often presented in the community ecology section of biology textbooks, but also can be demonstrated in the laboratory. We introduce a lab activity that uses an interactive strategy to teach high school and/or college students about this ecological concept.

Sensitive plant (Mimosa pudica) hiding time depends on individual and state. [PDF]
, 2017 The decisions animals make to adjust their antipredator behavior to rapidly changing conditions have been well studied. Inducible defenses in plants are an antipredator behavior that acts on a longer time scale, but sensitive plants, Mimosa pudica, have ...

Nonlinear Dynamic in an Ecological System with Impulsive Effect and Optimal Foraging
Abstract and Applied Analysis, 2014 The population dynamics of a three-species ecological system with impulsive effect are investigated. Using the theories of impulsive equations and small-amplitude perturbation scales, the conditions for the system to be permanent when the number of ...

Journal of Marine Science and Engineering, 2023 Aquaculture systems require careful consideration of location, which determines water conditions, pollution impacts, and hazardous conditions. Mobility may be able to address these factors while also supporting the targeting of renewable energy sources ...

Diving seabirds share foraging space and time within and among species
Ecosphere, 2010 Ecological theory predicts that animals with similar foraging strategies should not be able to co‐exist without segregating either in space, time or diet. In communities, intra‐specific competition is thought to be more intense than the competition among

Bacterial Foraging Based Channel Equalizers [PDF]
, 2006 A channel equalizer is one of the most important subsystems in any digital communication receiver. It is also the subsystem that consumes maximum computation time in the receiver.
