Optimally frugal foraging

Physical Review E, 2018
We introduce the \emph{frugal foraging} model in which a forager performs a discrete-time random walk on a lattice, where each site initially contains $\mathcal{S}$ food units. The forager metabolizes one unit of food at each step and starves to death when it last ate $\mathcal{S}$ steps in the past. Whenever the forager decides to eat, it consumes all

Urochloa hybrid adoption in Latin America and the Caribbean 2001–2024: an analysis of the land use, social, economic, and environmental impacts in 27 countries

Frontiers in Sustainable Food Systems
IntroductionSustainable intensification of tropical cattle production is essential to meet growing demand for animal-sourced foods while reducing environmental degradation. Improved interspecific Urochloa (syn. Brachiaria) hybrids have been promoted as a

Exposure of insects and host plants to different concentrations of CO2 affects the performance of Mahanarva spectabilis (Hemiptera: Cercopidae) in successive insect generations

Brazilian Journal of Biology, 2023
The performance of three successive generations of Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae) fed on four forages exposed to environments with different CO2 concentrations was evaluated.

Predicting Immediate Marginal Milk Responses and Evaluating the Economics of Two-Variable Input Tactical Feeding Decisions in Grazing Dairy Cows

Animals, 2021
Feed is the largest variable cost for dairy farms in Australia, and dairy farmers are faced with the challenge of profitably feeding their cows in situations where there is significant variation in input costs and milk price. In theory, the addition of 5.
