Resource allocation effects on the timing of reproduction in an avian habitat specialist

open access: yesEcosphere, 2021
Variation in nutrient allocation can influence the timing of breeding and ultimately reproductive output. Time and space constraints might exist, however, if fewer food resources are available to meet the costs of reproduction early during the ...

Econometric Production Models with Endogenous Input Timing: An Application to Ecuadorian Potato Production

open access: yesJournal of Agricultural and Resource Economics, 1994
In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous. The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for ...

Susceptibility to the common cold virus is associated with day length

open access: yesiScience, 2022
Summary: Seasonal rhythms are endogenous timing mechanisms that allow animals living at temperate latitudes to synchronize their physiology to the seasons. Human viral respiratory disease is prevalent in the winter at temperate latitudes, but the role of

Pupil response hazard rates predict perceived gaze durations

open access: yesScientific Reports, 2017
We investigated the mechanisms for evaluating perceived gaze-shift duration. Timing relies on the accumulation of endogenous physiological signals. Here we focused on arousal, measured through pupil dilation, as a candidate timing signal.

Cold spell en route delays spring arrival and decreases apparent survival in a long-distance migratory songbird

open access: yesBMC Ecology, 2017
Background Adjusting the timing of annual events to gradual changes in environmental conditions is necessary for population viability. However, adaptations to weather extremes are poorly documented in migratory species.

Interacting Roles of Breeding Geography and Early-Life Settlement in Godwit Migration Timing

open access: yesFrontiers in Ecology and Evolution, 2020
While avian migration timing is clearly influenced by both breeding and non-breeding geography, it is challenging to identify the relative and interdependent roles of endogenous programs, early-life experience, and carry-over effects in the development ...

Timing of sleep and its relationship with the endogenous melatonin rhythm

open access: yesFrontiers in Neurology, 2010
While much research has investigated the effects of exogenous melatonin on sleep, less is known about the relationship between the timing of the endogenous melatonin rhythm and the sleep-wake cycle.

Endogenous timing in duopolies

open access: yes, 2021
Tesis para optar al grado de Doctor en Sistemas de Ingeniería ; In this thesis we aim to understand how does leadership emerge in duopolistic competitions. In particular, we want to know which are the key features, of the firms and the market, that explain that some interactions are simultaneous while others are sequential.

Endogenous timing in the presence of non‐monotonicities

open access: yesCanadian Journal of Economics/Revue canadienne d'économique, 2020
AbstractThe aim of this paper is to generalize the endogenous timing game proposed by Hamilton and Slutsky (Games and Economic Behavior, 1990, 2, pp. 29–46) by allowing the payoff or the marginal payoff of a player to become non‐monotonic with respect to the strategy of the opponent. We propose a taxonomy of the subgame‐perfect Nash equilibria based on
