Density-dependent, central-place foraging in a grazing herbivore: competition and tradeoffs in time allocation near water [PDF]
, 2015 Optimal foraging theory addresses one of the core challenges of ecology: predicting the distribution and abundance of species. Tests of hypotheses of optimal foraging, however, often focus on a single conceptual model rather than drawing upon the ...

Collective foraging in heterogeneous landscapes [PDF]
arXiv, 2013 Animals foraging alone are hypothesized to optimize the encounter rates with resources through L\'evy walks. However, the issue of how the interactions between multiple foragers influence their search efficiency is still not completely understood. To address this, we consider a model to study the optimal strategy for a group of foragers searching for ...

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Arthropod biomass is a key element in ecosystem functionality and a basic food item for many species. It must be estimated through traditional costly field sampling, normally at just a few sampling points. Arthropod biomass and plant productivity should be narrowly related because a large majority of arthropods are herbivorous, and others ...

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]
, 2020 Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding

Phototaxic foraging of the archaepaddler, a hypothetical deep-sea species [PDF]
, 1998 An autonomous agent (animat, hypothetical animal), called the (archae) paddler, is simulated in sufficient detail to regard its simulated aquatic locomotion (paddling) as physically possible. The paddler is supposed to be a model of an animal that might

How anthropogenic noise affects foraging
Global Change Biology, 2015 The influence of human activity on the biosphere is increasing. While direct damage (e.g. habitat destruction) is relatively well understood, many activities affect wildlife in less apparent ways.

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs
Agribusiness, EarlyView.ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

Rarity begets rarity: Social and environmental drivers of rare organisms in cities
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

, 2016 This chapter focuses on conserving forage as hay or silage. Conserving forage is an essential component of ruminant livestock production systems in most temperate climates, but in subtropical and tropical regions the use of hay and silage is not as widespread.

Foraging behaviour of parasitoids in multi-herbivore communities
, 2016 Foraging behaviour of parasitoids in multi-herbivore communities Parasitic wasps, or parasitoids, use herbivore-induced plant volatiles and infochemicals produced directly by the herbivore to locate their herbivorous hosts.
