Hiding from swans: optimal burial depth of sago pondweed tubers foraged by Bewick’s swans
1 We used a combination of laboratory and field experiments to test the hypothesis that the burial depth of Potamogeton pectinatus tubers will vary with local sediment type and swan predation pressure. 2 In the field, mortality due to predation by swans decreased linearly with burial depth (from 100% at the surface to 55% at 225 mm depth) and with sediment clay content. Average tuber size showe...
متن کاملAdaptive Foraging: Effects of Resource Conditions on Search Paths in a Web-Based Foraging Game
Foraging is a search process common to mobile organisms, and foraging paths commonly exhibit statistical patterns akin to Lévy walks. There may be common factors and benefits underlying these patterns, but investigations are hindered by difficulty in assessing and manipulating search environments and task conditions. In the present study, a simple foraging game was developed to isolate and mani...
متن کاملRobust methods for the analysis of spatially autocorrelated data
In this paper we propose a new robust technique for the analysis of spatial data through simultaneous autoregressive (SAR) models, which extends the Forward Search approach of Cerioli and Riani (1999) and Atkinson and Riani (2000). Our algorithm starts from a subset of outlier-free observations and then selects additional observations according to their degree of agreement with the postulated m...
متن کاملCovariate influence in spatially autocorrelated occupancy and abundance data
The autologistic model and related auto-models, commonly applied as autocovariate regression, offer distinct advantages for analysing spatially autocorrelated species distribution or abundance data, allowing simple and direct modelling of the dependence of nearby observations. However, Carl and Kühn (Ecological Modelling, 2007, 207, 159) and Dormann (Ecological Modelling, 2007, 207, 234) questi...
متن کاملValid auto-models for spatially autocorrelated occupancy and abundance data
Spatially autocorrelated species abundance or distribution datasets typically generate spatially autocorrelated residuals in generalized linear models; a broader modelling framework is therefore required. Auto-logistic and related auto-models, implemented approximately as autocovariate regression, provide simple and direct modelling of spatial dependence. The autologistic model has been widely ...
