Demystifying the Graduate School Application Process

The Bulletin of the Ecological Society of America, Volume 104, Issue 1, January 2023., 2023
Abstract Navigating the graduate school application process is often challenging, requiring intricate knowledge of academia and graduate institutional structures. This “Hidden Curriculum of Academia” includes what different graduate degrees offer, how to connect with a faculty member of interest, and the skills needed to submit a “competitive ...

Corticosterone and foraging behaviour in a pelagic seabird [PDF]

, 2007
Because endocrine mechanisms are thought to mediate behavioral responses to changes in the environment, examining these mechanisms is essential for understanding how long-lived seabirds adjust their foraging decisions to contrasting environmental ...

Neural Mechanisms of Foraging [PDF]

Science, 2012
Looking for Greener Pastures Humans, like other animals, have evolved to forage. Brain-imaging studies by Kolling et al. (p. 95 ) suggest that activity in the dorsal anterior cingulate cortex supplies a continuous signal of environmental ...

The EU target for organic farming: Potential economic and environmental impacts of two alternative pathways

Applied Economic Perspectives and Policy, EarlyView.
Abstract The EU aims to reach 25% of the total agricultural area under organic farming by 2030. Interlinking a farm‐level and agro‐economic market model, we assess impacts of achieving the target either at Member State or aggregated EU level. Results show that flexible budget allocation across Member States would be more cost‐efficient and less ...

Does foraging efficiency vary with colony size in the fairy martin Petrochelidon ariel? [PDF]

, 2009
Colonial breeding occurs in a wide range of taxa, however the advantages promoting its evolution and maintenance remain poorly understood. In many avian species, breeding colonies vary by several orders of magnitude and one approach to investigating the ...

Foraging innovation in the guppy [PDF]

Animal Behaviour, 1999
When novel behaviour patterns spread through animal populations, typically one animal will initiate the diffusion. It is not known whether such 'innovators' are particularly creative individuals, individuals exposed to the appropriate environmental contingencies, or individuals in a particular motivational state.

Linking root traits to nutrient foraging in arbuscular mycorrhizal trees in a temperate forest.

New Phytologist, 2015
The identification of plant functional traits that can be linked to ecosystem processes is of wide interest, especially for predicting vegetational responses to climate change.

Efficiency functionals for the Lévy flight foraging hypothesis [PDF]

arXiv, 2022
We consider a forager diffusing via a fractional heat equation and we introduce several efficiency functionals whose optimality is discussed in relation to the L\'evy exponent of the evolution equation. Several biological scenarios, such as a target close to the forager, a sparse environment, a target located away from the forager and two targets ...

The effects of spatially heterogeneous prey distributions on detection patterns in foraging seabirds [PDF]

PLoS ONE 7(4) e34317, 2012, 2011
Many attempts to relate animal foraging patterns to landscape heterogeneity are focused on the analysis of foragers movements. Resource detection patterns in space and time are not commonly studied, yet they are tightly coupled to landscape properties and add relevant information on foraging behavior.

Impact of index insurance on downside income risk: Evidence from northern Kenya

Applied Economic Perspectives and Policy, EarlyView.
Abstract We assessed the impact of index‐based livestock insurance (IBLI) on household income and its higher‐order moments (i.e., variance and skewness). The study uses four waves of panel survey data from northern Kenya and applies a two stage least squares (2SLS) instrumental variables regression to estimate the causal impacts.
