1. Many paths, one destination: mapping the movements of a kleptoparasitic spider on the host’s web

Abstract:
... Kleptoparasitic spiders live and forage in the webs of other spiders. Using vibratory cues generated by the host spider during prey capture, they leave their resting positions in the upper peripheries of the host web and move towards the centre of the web where they feed along with the host spider or steal small pieces of prey. While the triggers for initiating the foraging raids are known, there ...

Abstract:
... Animals often change their behaviour in the presence of other species and the environmental context they experience, and these changes can substantially modify the course their populations follow. In the case of animals involved in mutualistic interactions, it is still unclear how to incorporate the effects of these behavioural changes into population dynamics. We propose a framework for using pol ...

Common pool resources, such as forests, shrubs, and grasslands, have been and continue to deliver a valuable contribution to the livelihood of millions of smallholder farmers in the mixed farming system areas. However, these resources are threatening by the overuse of the local community in the Ethiopian highlands. Studies accommodating sustainable management of ecological, economic, social, and i ...

Abstract:
... Some estimates suggest that almost a quarter of European households have members that forage, that is, pick wild products. Thus, foraging remains an important way for people to engage with their surrounding environment. Foraging has been associated both with the potential negative impacts it may have and with the potential positive effects it may bring. This article engages with the diversity of f ...

Abstract:
... Habitat characteristics and microhabitat of organisms pose a number of choices to foraging species, for example where and how to search for prey, which prey to select and what foraging technique to employ. Predators can enhance the profitability of foraging by adapting their strategies flexibly in relation to prey characteristics and environmental factors. To investigate the influence of rocky sho ...

Abstract:
... When social animals forage together, they may engage in frequency-dependent strategies either as producers, those who acquire food with their own energy, or as scroungers, those who feed on what the producers discover. An individual's choice of strategy may depend on the frequency of strategies within the group, or it may depend on the individual's own traits. Most of our understanding of producer ...

Abstract:

We tested the hypothesis that carnivorous plants also benefit from group foraging to improve the efficiency of trapping large prey using Drosera makinoi (Droseraceae). As a result of our field observations, it was found that larger neighboring D. makinoi density yields a greater number of larg ...

Abstract:
... Hydroacoustics is used broadly to assess fish populations in marine and freshwater systems. Large-scale surveys often employ multiple vessels to complete a survey. Vessels can be a source of variation in multi-vessel surveys, and accounting for this variation is critical to precise and accurate assessments, whether as indices or measures of absolute abundance. We examined areal and volumetric dens ...

Abstract:
... Double‐annual cropping systems can increase the productivity of farmland and simultaneously confer environmental benefits, but the optimal combination of crops and cultivation strategies is likely to be region‐specific. For instance, because of the low precipitation and specially in the summer, in Mediterranean environments irrigation is usually needed to grow two crops within a year. In the prese ...

To provide adequate forage to satisfy welfare requirements for nutrition, gut health and behavioural needs, the use of automated feeding is also increasing. Studies on forage intake rate report wide variation but provide litt ...
