Data for "An application of upscaled optimal foraging theory using hidden Markov modelling: year-round behavioural variation in a large arctic herbivore"
<p>Data for the article “An application of upscaled optimal foraging theory using hidden Markov modelling: year-round behavioural variation in a large arctic herbivore”</p> <p>By LT Beumer, J Pohle, NMS Schmidt, M Chimienti, JP Desforges, LH Hansen, R Langrock, SH Pedersen, M Stelvig, FM van Beest</p> <p> </p> <p>The data set includes three files: A readme file describing the data files and two data files accompanying the above publication.</p> <p>Combined, the two data files represent the dataset collected by GPS collars fitted on 19 female muskoxen in northeast Greenland (28 muskox-years with 153-1062 observation days/animal) and associated extracted covariates, divided into a summer and winter season dataset as modelled in the article. Data here are given as included in the models (for a description of cleaning procedures, see article). All continuous, non-cyclical covariates were standardised to have zero mean and unit standard deviation to improve numerical stability of parameter estimation.

Generalised host-plant feeding can hide sterol specialised foraging behaviours in bee-plant interactions
<p><span><span><span><span><span><span><span><span><span><span><span>Host-plant selection is a key factor driving the ecology and evolution of insects. While the majority of phytophagous insects are highly host specific, generalist behaviour is quite widespread among bees and presumably involves physiological adaptations that remain largely unexplored. However floral visitation patterns suggest that generalist bees do not forage randomly on all available resources. While resource availability and accessibility as well as nectar composition have been widely explored, pollen chemistry could also have an impact on the range of suitable host-plants. This study focuses on particular pollen nutrients that cannot be synthesised de novo by insects but are key compounds of cell membranes and the precursor for moulting process: the sterols. We compared the sterol composition of pollen from the main host-plants of three generalist bees: <i>Anthophora plumipes</i>,<i>Colletes cunicularius</i>and <i>Osmia cornuta</i>, as well as one specialist bee <i>Andrena vaga</i>. We also analysed the sterols of their brood cell provisions, the tissues of larvae and non-emerged females to determine which sterols are used by the different species. Our results show that sterols are not used accordingly to foraging strategy: Both the specialist species <i>Andrena vaga</i>and the generalist species <i>Colletes cunicularius</i>might metabolise a rare C<sub>27</sub>sterol, while the two generalist species <i>Anthophora plumipes</i>and <i>Osmia</i><i>cornuta</i>might rather use a very common C<sub>28</sub>sterol. Our results suggest that shared sterolic compounds among plant species could facilitate the exploitation of multiple host-plants by <i>A. plumipes</i>and <i>O. cornuta</i>whereas the generalist <i>C. cunicularius</i>might be more constrained due to its physiological requirements of a more uncommon dietary sterol. Our findings suggest that a bee displaying a generalist foraging behaviour may sometimes hide a sterol-specialised species. This evidence challenges the hypothesis that all generalist free-living bee species are all able to develop on a wide range of different pollen types.</span></span></span></span></span></span></span></span></span></span></span></p>
Geographic, temporal and individual factors influencing foraging behaviour and consistency in Australasian gannets
<p><span>Foraging is a behaviour that can be influenced by multiple factors and is highly plastic. Recent studies have shown consistency in individual foraging behaviour has serious ecological and evolutionary implications within species and populations. Such information is crucial to understand how species select habitats, and how such selection might allow them to adapt to the environmental changes they face. Five foraging metrics (maximum distance from the colony, bearing from the colony to the most distal point, tortuosity index, total number of dives and mean Vectorial Dynamic Body Acceleration were obtained using GPS tracking and accelerometry data in adult Australasian gannets (<i>Morus serrator</i>) from two colonies in south-eastern Australia. Individuals were instrumented over two breeding seasons to obtain data to assess factors influencing foraging behaviour and behavioural consistency over multiple timescales (consecutive trips, breeding stages and years) and habitats (pelagic, mixed pelagic and inshore, and inshore). Colony, breeding stage and year were the factors which had the greatest influence on foraging behaviour, followed by sex. Behavioural consistency, measured as the contribution of the individual to the observed variance, was low to moderate for all foraging metrics (0.0 to 27.05%), with the higher values occurring over shorter timescales. In addition, behavioural consistency was driven by spatio-temporal factors rather than intrinsic characteristics. Behavioural consistency was higher in individuals foraging in inshore than pelagic habitats or mixed pelagic/inshore strategy, supporting suggestions that consistency is favoured in stable environments.</span></p>
