Abstract:
Foraging behaviour is one of the distinctive behaviours of honey bees, Apis mellifera. This behaviour is the link between the honey bee colony and the ambient environment. Therefore, various in-colony and out-colony factors have an impact on this behaviour, and many studies have been employed to investigate these factors. Foraging behaviour is not advantageous only for the colony and for plant pollination but also has other benefits. In contrast, some disadvantages have also been discovered to be linked with foraging activity. Practically speaking, the control over this behaviour is very important to maximize colony products as well as to increase other agricultural benefits. This paper presents a review on foraging activity including; the regulation of foraging tasks, factors impacting this behaviour, foraging preference, variations between subspecies, monitoring methods as well as the possible methods for controlling this behaviour. As concluded from this review, more work needs to be performed in order to elucidate certain aspects of foraging behaviour.

Abstract:
Many shorebirds are long-distance migrants and they congregate on intertidal mudflats for feeding throughout their non-breeding season. Despite being one of the key staging sites for migratory shorebirds, data on shorebirds foraging ecology in Sarawak is insufficient for the understanding of the interaction between shorebirds and their behaviour. This study aimed to determine the foraging behaviour of Whimbrel (Numenius phaeopus), Bar-tailed Godwit (Limosa lapponica) and Terek Sandpiper (Xenus cinereus) at Asajaya and Buntal mudflats. Data collection of this study was conducted at low tide, during two non-breeding seasons with a total of 12 months of sampling. Focal observations were conducted within a 50 m × 50 m quadrat. A total of 8 exclusive foraging techniques were observed for the three shorebird species, including: pecking, probing, picking, stabbing, snapping, submerging, sweeping and ingesting. Terek Sandpiper displayed all the exclusive foraging behaviours, whereas Whimbrel and Bar-tailed Godwit showed 7 and 5 behaviours, respectively. The three shorebirds also displayed non-exclusive foraging behaviours such as walking, preening and defecating. Spearman correlation test indicates a positive correlation between the foraging behaviours performed among three shorebird species. All three shorebird species adopted similar mixed foraging strategies comprising pecking and probing, with an exception on supplementary behaviours observed in Whimbrel and Terek Sandpiper. Principal Component Analysis (PCA) analysis showed a strong correlation between picking and ingesting behaviours, suggesting a high chance of foraging success with the presence of picking behaviour. The outcome of this study is crucial in understanding how shorebirds maximise their behavioural performance when foraging as well as to assist in formulating better conservation strategies for targeted migratory shorebird species and coastal mudflats.

Abstract:
Context The risk-disturbance hypothesis predicts that animals exhibit risk-avoidance behaviours when exposed to human disturbance because they perceive the disturbance as a predatory threat. Aims This study aimed to examine whether Tibetan antelopes (Pantholops hodgsoni) exhibit risk-avoidance behaviour with proximity to a major highway and with increasing traffic flow consistent with the risk-disturbance hypothesis. Methods Focal-animal sampling was used to observe the behaviour of Tibetan antelopes. The behaviours were categorised as foraging, vigilance, resting, moving, or other. The time, frequency, and duration of foraging and vigilance were calculated. Key results As distance from the road increased, time spent foraging and foraging duration increased while foraging frequency, time spent being vigilant and vigilance frequency decreased, indicating that there is a risk perception associated with roads. Tibetan antelopes presented more risk-avoidance behaviours during high-traffic periods compared with low-traffic periods. Conclusions Tibetan antelopes exhibited risk-avoidance behaviour towards roads that varied with proximity and traffic levels, which is consistent with the risk-disturbance hypothesis. Implications The consequences of risk-avoidance behaviour should be reflected in wildlife management by considering human disturbance and road design.

Abstract:
Food restriction appears to be a contributory factor in the development of stereotypic behaviour in sows. The sustained feeding motivation following the ingestion of a small meal of concentrated food results in high levels of foraging in the post-prandial period. In the absence of a suitable foraging substrate to facilitate the expression of complex behaviours, foraging may be channelled into a limited number of highly repetitive behavioural sequences (Lawrence and Terlouw 1993). High fibre diets may mitigate the development of such behaviours (Brouns, Edwards and English 1994) by providing increased gut fill in the post-prandial period, thereby reducing foraging motivation and consequently the need for a foraging substrate. The aim of this study was to examine the interactive effects of a high fibre diet and the provision of straw on levels of stereotypic behaviour in sows.

Abstract:
Foraging theory is a well established set of models and ideas in ecology, anthropology and behavioural psychology. Two areas of research, the behavioural ecology of consumption and information foraging, have made strides in the application of foraging theories in relation to consumption and related behaviours. These focus on online situations and restrictions in methodologies utilized allows application to only a small range of marketing problems. This paper broadens the application of these notions and introduces foraging ideas/terminology to a wider business and marketing audience by contextualizing and comparing with current research in marketing and related areas. The paper makes a number of suggestions for use of the foraging model in both academic and practitioner based environments. The paper ends with discussion of future research on the assembly and wider application of a foraging ecology model of consumer behaviour.

Abstract:
Understanding the behaviour of animals in the wild is fundamental to conservation efforts. Advances in bio-logging technologies have offered insights into the behaviour of animals during foraging, migration and social interaction. However, broader application of these systems has been limited by device mass, cost and longevity. Here, we use information from multiple logger types to predict individual behaviour in a highly pelagic, migratory seabird, the Manx Shearwater ( Puffinus puffinus ). Using behavioural states resolved from GPS tracking of foraging during the breeding season, we demonstrate that individual behaviours can be accurately predicted during multi-year migrations from low cost, lightweight, salt-water immersion devices. This reveals a complex pattern of migratory stopovers: some involving high proportions of foraging, and others of rest behaviour. We use this technique to examine three consecutive years of global migrations, revealing the prominence of foraging behaviour during migration and the importance of highly productive waters during migratory stopover.

Abstract:
AbstractDetailed analyses of dolphin foraging behaviour have typically been difficult due to researchers' inability to observe entire foraging sequences. Using a new observational tool I was able to observe sequences of behaviours leading to successful prey captures, including behaviours not previously described in Sarasota Bay dolphins. I defined a set of specific foraging behaviours and demonstrated their position in successful sequences by analyzing the conditional probability of their occurrence based the occurrence of a capture. The sequences of behaviours dolphins used were not deterministic, and individual dolphins displayed different behavioural repertoires. Foraging behaviours occurred at rates of up to 0.5 per minute during general activity categories commonly used in odontocete research, and the current results could assist in the interpretation of these activities.

Abstract:
The study of seabird behaviour has largely relied on animal-borne tags to gather information, requiring interpretation to estimate at-sea behaviours. Details of shallow-diving birds’ foraging are less known than deep-diving species due to difficulty in identifying shallow dives from biologging devices. Development of smaller video loggers allow a direct view of these birds’ behaviours, at the cost of short battery capacity. However, recordings from video loggers combined with relatively low power usage accelerometers give a means to develop a reliable foraging detection method. Combined video and acceleration loggers were attached to streaked shearwaters in Funakoshi-Ohshima Island (39°24’N,141°59’E) during the breeding season in 2018. Video recordings were classified into behavioural categories (rest, transit, and foraging) and a detection method was generated from the acceleration signals. Two foraging behaviours, surface seizing and foraging dives, are reported with video recordings. Surface seizing was comprised of successive take-offs and landings (mean duration 0.6 and 1.5s, respectively), while foraging dives were shallow subsurface dives (3.2s mean duration) from the air and water surface. Birds were observed foraging close to marine predators, including dolphins and large fish. Results of the behaviour detection method were validated against video recordings, with mean true and false positive rates of 90% and 0%, 79% and 5%, and 66% and <1%, for flight, surface seizing, and foraging dives, respectively. The detection method was applied to longer duration acceleration and GPS datasets collected during the 2018 and 2019 breeding seasons. Foraging trips lasted between 1 − 8 days, with birds performing on average 16 surface seizing events and 43 foraging dives per day, comprising <1% of daily activity, while transit and rest took up 55 and 40%, respectively. This foraging detection method can address the difficulties of recording shallow-diving foraging behaviour and provides a means to measure activity budgets across shallow diving seabird species.

Abstract:
Some animals optimize their foraging activity by learning and memorizing food availability, in terms of quantity and quality, and adapt their feeding behaviour accordingly. Here, we investigated whether cuttlefish flexibly adapt their foraging behaviour according to the availability of their preferred prey. In Experiment 1, cuttlefish switched from a selective to an opportunistic foraging strategy (or vice versa ) when the availability of their preferred prey at night was predictable versus unpredictable. In Experiment 2, cuttlefish exhibited day-to-day foraging flexibility, in response to experiencing changes in the proximate future (i.e. preferred prey available on alternate nights). In Experiment 1, the number of crabs eaten during the day decreased when shrimp (i.e. preferred food) were predictably available at night, while the consumption of crabs during the day was maintained when shrimp availability was unpredictable. Cuttlefish quickly shifted from one strategy to the other, when experimental conditions were reversed. In Experiment 2, cuttlefish only reduced their consumption of crabs during the daytime when shrimps were predictably available the following night. Their daytime foraging behaviour appeared dependent on shrimps' future availability. Overall, cuttlefish can adopt dynamic and flexible foraging behaviours including selective, opportunistic and future-dependent strategies, in response to changing foraging conditions.

Abstract:
Movements of animals form a vital link between individual behaviour and spatial processes affecting populations, communities and ecosystems. Predators often have to search for prey that is unpredictable or patchily distributed and increasingly have to do so in habitats that are changing as a result of climate change or anthropogenic activity. Our understanding of animal movement has been revolutionised by the development of miniaturised loggers which allow tracking of individual animals over a range of spatial and temporal scales. However, while flight heights of birds are a critical component of avian movement ecology, they have been little-studied in comparison to horizontal movements. In this thesis I examine the three-dimensional foraging behaviour of northern gannets (Morus bassanus) at the world's largest breeding colony, at Bass Rock, Scotland. I first combine GPS and pressure data to estimate flight heights, and develop a novel refinement that uses sea surface pressure data to correct estimated heights during long periods of sustained flight. I then investigate sexual differences and effects of weather on three-dimensional foraging behaviour, before examining potential population-level consequences of mortality from collisions with offshore wind turbines. I found that sexual differences in foraging behaviour extend to the heights at which birds fly, and that wind speed in particular has a marked effect on movements and behaviour at sea. I also found that predicted levels of mortality from offshore wind farms would be likely to retard population growth but unlikely to drive the population into long-term decline. My thesis describes some of the complexity and flexibility of gannet foraging behaviour and highlights the importance of understanding movements in three dimensions.

Abstract:
Social foraging behaviour has an important influence on individuals’ survival and reproduction through its role in the acquisition of food resources. It also determines the amount of foraging time required in differing environments, and so the amount of time available for other activities, such as socialising and resting, which have been implicated in an individual’s fitness, as well as the stability of the wider social group. In this thesis I explore the links between these two processes by investigating the drivers of social foraging behaviour, and how the foraging time budgets that this behaviour produces vary between environments. I do this using data collected from a wild population of chacma baboons (Papio ursinus) in Namibia, under both natural and field-experimental conditions, and through the development of an individual-based model (IBM). I show that baboon foraging decisions are influenced by social and non-social factors, but that the relative influence of these factors is dependent on the characteristics of the forager and the habitat it is in. These differences in decision-making appear to allow all individuals in a group to experience similar foraging success under natural conditions, but this pattern breaks down in extreme conditions. Using these findings to build an IBM of social foraging, I show that the time individuals need to spend foraging can increase rapidly in a deteriorating environment to the point where they are no longer able to gather enough resources. Overall, the findings of this thesis contribute to the growing appreciation that social foragers can exhibit a high degree of behavioural flexibility. These findings also emphasise the long-standing recognition that individual-level behaviours have an important influence on higher-level ecological patterns and processes and that an appreciation of this is important, not only for our understanding of these patterns and processes, but also for informing conservation and management.

Abstract:
This is a study of the foraging behaviour of Carcinus maenas on Mytilus edulis and of Thalamita danae on Perna viridis. Particular attention is given to differences arising in foraging behaviour as a result of intraspecific prey heterogeneity and experimental protocol. Intersite and temporal differences in the population density, shell morphology, biomass and byssal attachment strength of Mytilus edulis were found. Byssal attachment strength and shell strength were highly variable amongst individuals of a similar size. Carcinus maenas is strongly heterochelous. Intraspecific differences in the chelal mechanics, but not in the chelal geometry, were recorded; major chelae of large male crabs were significantly stronger than the major chelae of females and small males. Stomach content analyses showed that Carcinus maenas has a broad diet in which Mytilus edulis forms an important component. Intersite differences inMytilus edulis shell morphology altered the foraging behaviour of Carcinus maenas, and intersite and temporal variations in mussel flesh weight altered the prey value curves. Both C. maenas and Thalamita danae were highly prey size-selective when foraging on groups of different sized mussels, the size of prey most vulnerable to predation altering with the size composition of the group. The handling times of mussels for both species of crab were reduced when mussels were presented as part of a group as compared to when mussels were presented singly. For Carcinus maenas the reduced handling times resulted from the less extensive gleaning of mussel shells whilst for Thalamita danae reduced handling times appeared to result from the greater use of a more time efficient opening technique. When Carcinus maenas were presented with mussels of differing attachment strengths, crabs selected more weakly attached mussels over those with a more firm and rigid attachment. This selection did not appear to be based on prey value or prey length but rather on the resulting slight movement of weakly attached mussels whenever these were touched by a foraging crab.

Abstract:
The aim of this thesis was to understand the function of the frontal lobes during different types of decisions thusfar mostly neglected in cognitive neuroscience. Namely, I sought to understand how decisions are made when comparisons are not about a simple set of concrete options presented, but rather require a comparison with one specific encounter and a sense of the value of the current environment (Chapter 2-3). Additionally, I wanted to understand how decisions between concrete options can be contextualized by the current environment to allow considerations about changing environmental constraints to factor into the decision making process (Chapter 4-5). At last, I wanted to test how the potential for future behaviours within an environment has an effect on peoples decisions (Chapter 6). In other words, how do people construct prospective value when it requires a sense of own future behaviours? All this work was informed by concepts and models originating from optimal foraging theory, which seeks to understand animal behaviours using computational models for different ecological types of choices. Thus, this thesis offers a perspective on the neural mechanisms underlying human decision making capacities that relates them to common problems faced by animals and presumably humans in ecological environments (Chapter 1 and 7). As optimal foraging theory assumes that solving these problems efficiently is highly relevant for survival, it is possible that neural structures evolved in ways to particularly accommodate for the solution of those problems. Therefore, different prefrontal structures might be dedicated to unique ways of solving ecological kinds of decision problems. My thesis as a whole gives some evidence for such a perspective, as dACC and vmPFC were repeatedly identified as constituting unique systems for evaluation according to different reference frames. Their competition within a wider network of areas appeared to ultimately drive decisions under changing contexts. In the future, a better understanding of those changing interactions between these prefrontal areas which generate more complex and adaptive behaviours, will be crucial for understanding more natural choice behaviours. For this temporally resolved neural measurements as well as causal interference will be essential.

Abstract:
This paper presents an application of the Bees Algorithm (BA) to the optimisation of weights within neural networks for wood defect detection. This novel population-based search algorithm mimics the natural foraging behaviour of swarms of bees. In its basic version, the algorithm performs a kind of neighbourhood search combined with random search. Following a brief description of the algorithm, the paper gives the results obtained for the wood defect identification problem demonstrating the efficiency and robustness of the new algorithm.

Abstract:
We present a method for reasoning about fault-tolerance in unbounded robotic swarms. We introduce a novel semantics that accounts for the probabilistic nature of both the swarm and possible malfunctions, as well as the unbounded nature of swarm systems. We define and interpret a variant of probabilistic linear-time temporal logic on the resulting executions, including those arising from faulty behaviour by some of the agents in the swarm. We specify the decision problem of parameterised fault-tolerance, which concerns determining whether a probabilistic specification holds under possibly faulty behaviour. We outline a verification procedure that we implement and use to study a foraging protocol from swarm robotics, and report the experimental results obtained.

Abstract:
Ant foraging behavior has inspired research in a number of areas including distributed problem solving such as optimization and task allocation and mobile robot navigation. In the area of swarm robotic systems, ant foraging behavior has been largely modeled via behavior based techniques and analyzed using cellular automata. Development of continuous time models for ant foraging can potentially provide insights into new mechanisms and behaviors used by ants that provide self-organizing capabilities to the ant colony. This paper presents a distributed control law in continuous time that combines gradient following for pheromone concentration as well as food scent with random motion seen in ants. The paper also provides a continuous time model for pheromone laying in a 2D environment and carries out a preliminary numerical stability analysis of the solutions. Extensive simulation studies confirm emergent behaviors seen in ant systems such as trail formation and convergence to single food site. In addition, the paper examines the effect of randomness on robustness of convergence to a single food site.

Abstract:
Algorithms used in networking, operation research and optimization can be created using bio-inspired swarm behaviors, but it is difficult to mimic swarm behaviors that generalize through diverse environments. State-machine-based artificial collective behaviors evolved by standard Grammatical Evolution (GE) provide promise for general swarm behaviors but may not scale to large problems. This paper introduces an algorithm that evolves problem-specific swarm behaviors by combining multi-agent grammatical evolution and Behavior Trees (BTs). We present a BT-based BNF grammar, supported by different fitness function types, which overcomes some of the limitations in using GEs to evolve swarm behavior. Given human-provided, problem-specific fitness-functions, the learned BT programs encode individual agent behaviors that produce desired swarm behaviors. We empirically verify the algorithm's effectiveness on three different problems: single-source foraging, collective transport, and nest maintenance. Agent diversity is key for the evolved behaviors to outperform hand-coded solutions in each task.

The Prediction of Daily Intake in Grazing Cattle Using Methodologies, Models and Experiments that Integrate Pasture Structure and Ingestive Behavior. United States Department of Agriculture, July 1994. http://dx.doi.org/10.32747/1994.7568789.bard.

Abstract:
This project addressed the prediction of daily intake in grazing cattle using methodologies, models and experiments that integrate pasture structure and ingestive behavior. The broad objective was to develop concepts of optimal foraging that predicted ingestive behavior and instantaneous intake rate in single and multi-patch environments and extend them to the greater scales of time and space required to predict daily intake. Specific objectives included: to determine how sward structure affects the shape of patch depletion curves, to determine if the basic components of ingestive behavior of animals in groups differs from animals alone, and to evaluate and modify our existing models of foraging behavior and heterogeneity to incorporate larger scales of time and space. Patch depletion was found to be predominantly by horizon, with a significant decline in bite weight during horizon depletion. This decline derives from bite overlap, and is more pronounced on taller swards. These results were successfully predicted by a simple bite placement simulator. At greater spatial scales, patch selection was aimed at maximizing daily digestible intake, with the between patch search pattern being non-random. The processes of selecting a feeding station and foraging at a feeding station are fundamentally different. The marginal value theorem may not be the most appropriate paradigm for predicting residence time at a feeding station. Basic components of ingestive behavior were unaffected by the presence of other animals. Our results contribute to animal production systems by improving our understanding of the foraging process, by identifying the key sward parameters that determine intake rate and by improving existing conceptual and quantitative models of foraging behavior across spatial and temporal scales.
