Abstract:
Users' engagement with pervasive displays has been extensively studied, however, determining how their content is interesting remains an open problem. Tracking of body postures and gaze has been explored as an indication of attention; still, existing works have not been able to estimate the interest of passers-by from readily available data, such as the display viewing time. This article presents a simple yet accurate method of estimating users' interest in multiple content items shown at the same time on displays. The proposed approach builds on the information foraging theory, which assumes that users optimally decide on the content they consume. Through inverse foraging, the parameters of a foraging model are fitted to the values of viewing times observed in practice, to yield estimates of user interest. Different foraging models are evaluated by using synthetic data and with a controlled user study. The results demonstrate that inverse foraging accurately estimates interest, achieving an R2 above 70% in comparison to self-reported interest. As a consequence, the proposed solution allows to dynamically adapt the content shown on pervasive displays, based on viewing data that can be easily obtained in field deployments.

Abstract:
Pollination is an intricate relationship between plants and pollinators; this interaction is the best example of mutualism where pollinators utilize floral rewards while pollination accomplished on plants. Pollination ecology of tulsi (Ocimum basilicum) is poorly understood. Foraging attributes: foraging rate, foraging speed and transit time of pollinators are key performance indicator to determine their pollination efficiency. Foraging speed and foraging rate were recorded during blooming period with the help of stopwatch and transit time was calculated from foraging rate and foraging speed. The performance of seven pollinators; Apis florea, Amegilla cingulata, Megachile femoratella, Megachile sp., Apis cerana, Apis dorsata and Apis mellifera were evaluated on the basis of foraging attributes. Foraging rate, foraging speed and transit time varied during the blooming period week to week and pollinator species to species. The maximum foraging rate was observed with A. mellifera, maximum foraging speed was observed with A. florea and minimum transit time as well as wasted minimum time was calculated with A. mellifera. The maximum foraging rate, foraging speed and minimum transit time were observed with all the pollinators at the peak of blooming period. Based on foraging attributes A. mellifera performance was better than other pollinators on Tulsi.

Abstract:
Some visually foraging planktivorous fish will facultatively engage in nonvisual foraging when opportunities arise or necessity dictates. Yet, little is known about the ecology of nonvisual foraging. We examined the roles of prey size, fish size, and prey density on the nonvisual foraging of walleye pollock, Theragra chalcogramma (40–100 mm total length), and sablefish, Anoplopoma fimbria (66–89 mm), in the laboratory. Both species were size selective, disproportionately consuming large prey just as they do during visual foraging. Large prey were encountered more often, presumably because they were more easily detected by the fish's lateral-line system. When foraging visually, larger fish consumed more prey, but during nonvisual foraging, there was no foraging advantage to greater fish size. Unlike visual detection distances, lateral-line detection distances may not increase appreciably with fish size. Lastly, prey density influenced nonvisual prey consumption. Walleye pollock were characterized by a type I functional response, whereas sablefish were characterized by a type II functional response. Models of planktivore foraging typically assume negligible foraging by particulate feeders below their visual foraging thresholds. On the basis of this study and field data, we suggest that foraging models for particulate feeders, such as juvenile walleye pollock and sablefish, should account for nonvisual size-selective foraging.

Full text
Abstract:
The paper describes the foraging ecology of the Australian desert ant, Melophorus bagoti, a thermophilic, diurnal scavenger with ground-nesting colonies. Overlapping foraging ranges, low foraging success rates, and intercolony aggression suggest intense competition for food between colonies. Daily foraging starts when soil surface temperatures approach 50°C. Workers search individually and collect predominantly dead insects. Occasionally, they consume plant secretions. Foraging activity peaks on mid-summer days. On cloudy days the onset of foraging is delayed, and the foraging activity is low. Ants do not forage on rainy days. Typically, workers start their above-ground activities with a few short exploration runs. On average, they perform one foraging run on the first day of their outdoor lives. With age they gradually increase foraging site fidelity and daily foraging effort. Individual foraging efficiency is low at the beginning but grows with experience. However, due to a high mortality rate and, hence, high forager turnover, average rates of foraging success for a colony remain rather low. The outdoor activity gradually decreases towards the end of summer and appears to stop completely during the winter months.

Full text
Abstract:
Foraging behaviour is crucial to breeding success for marine predators, including seabirds. Yellow-eyed penguins Megadyptes antipodes are central-place, predominantly benthic foragers around mainland New Zealand. The northern (mainland) population of this Endangered species is declining, with changes in the marine environment a suspected cause, particularly warming water and poorer foraging success. We undertook a detailed foraging study of the data-deficient subantarctic population, which is distinct from the northern population. Over 2 breeding seasons, we collected 91 GPS foraging logs from 69 breeding yellow-eyed penguins from Enderby Island, Auckland Islands, New Zealand. The mean foraging distance was 24 km from shore (max 47 km). Foraging area size was greater for females and for pelagic foragers, although benthic foragers travelled further from shore on average. Diving plasticity was evident both in diving behaviour and foraging area use. Foraging area and distance from shore were greater for all birds in a year of greater breeding effort and fledging success (2016). Foraging occurred over continental shelf waters, similar to the mainland, and in areas up to 150 m deep, so any differences in foraging behaviour compared to those reported for the northern population are likely influenced by local bathymetry, environmental conditions, and individual preference. Despite comparable bathymetry in some areas, the southern population showed greater foraging plasticity, with 62% of foraging trips categorised as pelagic, implying that subantarctic foraging conditions may differ from the predominantly benthic mainland foraging. Variable foraging conditions may therefore have implications for future breeding success in the subantarctic.

Abstract:
Explaining the mechanism of the coexistence of sympatric species is an important goal of ecology. Five species of woodpeckers coexist in the broadleaved Korean pine forest of Liangshui National Nature Reserve, including the Black Woodpecker (Dryocopus martius), Great Spotted Woodpecker (Dendrocopos major), Lesser Spotted Woodpecker (Dendrocopos minor), Three-toed Woodpecker (Picoides tridactylus), and White-backed Woodpecker (Dendrocopos leucotos). Woodpeckers are considered to be keystone species because of their role as ecosystem engineers, creating breeding and shelter sites for many vertebrate and invertebrate taxa. As woodpeckers are predominant in primary forests, they are sensitive to changes in forest ecosystems. To understand their coexistence mechanisms and propose conservation strategies, it is necessary to investigate their foraging niche differentiation. This study aimed to identify the foraging behavior parameters and foraging tree parameters of five woodpecker species in Liangshui Reserve from October to December. The foraging niches of five woodpecker species were observed, including the type of foraging techniques, foraging height, foraging site, foraging duration, tree species being foraged upon, diameter of the foraging tree at breast height, foraging tree height, and decay status of trees. Our results identified that there were significant differences in the overall foraging ecology of the five species of woodpecker at Liangshui Reserve. The Great Spotted Woodpecker and Lesser Spotted Woodpecker had more diverse foraging patterns and preferred to forage on live trees. The Black Woodpecker and Three-toed Woodpecker excavated and pecked at the trunks of decaying spruce and fir trees. The White-backed Woodpecker preferred to forage in broadleaved trees. The choice of foraging sites was complicated. The size of the foraging trees and decay status of trees were important bases for woodpeckers when choosing trees to forage from. Different woodpeckers achieve stable coexistence through the separation of their foraging niches. This information regarding foraging behavior and foraging tree characteristics provides a basis to study the coexistence patterns of woodpeckers. Our research into woodpecker foraging should be used to inform forest management practices, protect forest ecosystem diversities, and maintain woodpecker community diversity.

Full text
Abstract:
Abstract Adjusting foraging strategies is a common phenomenon within groups of animals competing for the same resource. In polytocous mammals, neonates concurrently compete for limited milk and alternate between two foraging (suckling) strategies: adaptable exploratory foraging with random sampling of teats, and ordered foraging with a tendency towards exploiting a particular suckling position. Some theoretical (game theory) models have shown that weaker siblings in particular benefit from foraging specialization (suckling order). Neonate piglets establish a well-defined suckling order that develops gradually and fluctuates throughout the lactation period, implying the existence of inter-individual differences in foraging strategies. We therefore analyzed suckling behavior in pigs to determine whether one foraging strategy was more beneficial to neonates in terms of their body weight and foraging environment. We found that intermediate and heavy littermates tended to adjust their suckling strategy according to the foraging environment; however, the selected foraging strategy did not affect their overall growth performance. Lighter individuals that consumed significantly less milk did not greatly alternate their foraging strategy according to the foraging environment, but their growth rate was significantly higher whenever they performed less-exploratory foraging behavior. Although suckling order appeared to be a relatively stable behavioral phenotype, it was beneficial exclusively for weaklings. These results confirm theoretical predictions and indicate that specializing in a suckling position is a beneficial strategy for weaker, light neonates. These findings suggest that physically weaker neonates might have driven the evolution of neonatal foraging specialization.

Abstract:
The analysis of feeding strategies in animals is one of the most important topics in foraging ecology. The individual’s foraging behavior depends on both the individual’s own actions and the behavior of other foragers. Here we analyse the effect of the sex and group size on the foraging behavior of immature Olrog’s Gull (Larus atlanticus Olrog, 1958), endemic to the Atlantic coast of southern South America and regionally listed a threatened species. Birds were captured, banded, sexed, and aged during the non-breeding season in Mar Chiquita coastal lagoon, Argentina. The foraging behavior was quantified by observations made on individuals of known identity, recording the size of foraging groups, as well as prey size and type. Foraging parameters estimated were foraging effort, capture rate, and foraging efficiency. Males spent more time in agonistic behavior and captured larger prey. With an increase in group size, the capture rate, the capture of small crabs by males, and the foraging effort were higher. The agonistic behaviors, size of consumed prey, and foraging effort were affected by individual identity. Our study pinpoints factors underlying variation in the foraging behavior of Olrog’s Gulls and illustrates the importance of modelling individual variation when analyzing foraging behavior.

Abstract:
Based on animal long-term and short-term memory radial foraging techniques (or LMRFT and SMRFT), we devise a modelling approach that could capture the foraging behaviours of animals. In this modelling, LMRFT-based optimal foraging paths and SMRFT-based ones are constructed with respect to different levels of foraging strategies. Then, by a devised structural metric, we calculate the structural distance between these modelled optimal paths and the hypothetical real foraging paths taken by agents. We sample 20 foods positions via a chosen bivariate normal distribution for three agents. Then, we calculate their Euclidean distance matrix and their ranked matrix. Using LMRFT-based or SMRFT-based optimal foraging strategies, the optimal foraging paths are created. Then, foraging strategies are identified using optimal parameter learning techniques. Our results, based on the simulated foraging data, show that LMRFT-based foraging strategies for agent 1,2 and 3 are 3, 2 and 5, i.e., agent 3 is the most intelligent one among the three in terms of radial level. However, from the SMRFT-based perspective of strategies, their optimal foraging strategies are 5,5 and 2, respectively, i.e., agent 1 is as intelligent as agent 2 and both of them have better SMRFT-based foraging strategies than agent 3.

Abstract:
Foraging behaviors of wintering gadwall (Anas strepera), pintail (Anas acuta), and green-winged teal (Anas crecca carolinensis) were studied at Bodie Island, North Carolina. Foraging speed (metres per minute) and rate of foraging (dips per minute) did not differ by sex, but significant monthly variation of foraging components occurred for all species. Ducks fed at faster rates and increased their foraging speed as winter progressed. Stepwise multiple regression procedures were used to test the effects of day length (minutes), mean daily temperature (degrees Celsius), mean daily wind speed (kilometres per hour), water depth (centimetres), and density of foraging individuals on the temporal variation in rate and speed of foraging. Changes in the foraging speed and rate of dipping of winter ducks were significantly related to decreases in day length and average daily temperatures. Other environmental parameters had variable effects on foraging behavior. Estimates of total prey biomass did not vary significantly during winter; however, changes in the distribution of prey sizes may have contributed to changes in foraging behavior. Greater foraging speed and rate of dipping may have been a behavioral mechanism which increased ingestion rate and minimized foraging time, thereby allowing wintering ducks to reduce thermal stress through modification of activity patterns and selection of more favorable microclimates.

Abstract I studied year-round foraging behavior of 28 color-banded Eurasian Three-toed Woodpeckers (Picoides tridactylus alpinus) from 1995 to 1999 in Berchtesgaden National Park, Germany. My research focused on how foraging time was divided among various substrates and foraging techniques. Foraging behavior was recorded by instantaneous sampling during independent observation sessions (i.e. foraging bouts). A combination of tapping and pecking was the most important foraging technique used during breeding (>43%) and nonbreeding (>59%). Both mean and maximum foraging bouts (mean ± SD) lasted longer during nonbreeding periods (mean: 17.0 ± 3.7 min, maximum: 61.9 ± 30.2 min) than during breeding periods (4.3 ± 3.0 min, 15.5 ± 16.1 min). Sap-sucking was observed rarely during breeding. Males spent less time foraging on branches, whereas females spent less time in the lower third of trees on which they foraged. Males also manipulated foraging substrates more by pecking and digging (probing), whereas females did more climbing and position-changing on foraging trees. I concluded that Eurasian Threetoed Woodpeckers changed their foraging techniques according to seasonal changes in diet and that, during breeding, males used better foraging grounds than females.

Abstract:
Marine heatwaves are increasing in frequency and can disrupt marine ecosystems non-linearly. In this study, we examined the effect of the North Pacific warming event of 2014, the largest long-term sea surface anomaly on record, on black-legged kittiwake Rissa tridactyla foraging trips before, during, and after the event. We assessed foraging trip characteristics (trip distance and duration), the dispersal of foraging locations, and the persistence of foraging areas within and among years. Foraging trip characteristics, foraging area size, and location varied from year to year. Kittiwake foraging was more dispersed, direct, and farther from the colony in years immediately after and during the warming event. A third of the foraging area used pre-heatwave (2012) was important in subsequent years, which indicates that this area was, and may still be, a perennial foraging hot spot. During the chick-rearing stage, black-legged kittiwakes increased their speed and reduced the proportion of resting compared to the incubation stage. We conclude that marine heatwaves may have a strong impact on seabird foraging, extending foraging ranges, and that those impacts may be nonlinear with a strong lag.

Abstract:
Ecological communities appear to have structure, and exploitation of food resources have commonly been implicated in contributing to that apparent structure. Avian communities are frequently used in foraging research, but such studies do not usually document within-landscape patterns of change over seasonal time. I studied a guild of twelve small, foliage-gleaning, insectivorous songbirds in their breeding landscape in central Ontario, Canada. By focussing on foraging preferences indicated by tree species, foraging height, and foraging maneuvers, I compared patterns among the breeding period (June), midsummer (late July and early August), and early autumn (late August to mid September) within the one landscape. Correspondence analysis indicates that each species foraged in a distinct manner, yet there was substantial foraging overlap at all times in preferred (i) foraging tree species, (ii) foraging height, and (iii) foraging maneuvers. As the season progressed, patterns related to preferred foraging height and foraging maneuvers did not change dramatically. However, patterns of preferred foraging tree species did change progressively from breeding to autumn. During the breeding period, the guild tended to exploit different tree species in a manner correlated with the relative availabilities of those species, but this was not the case in midsummer or autumn. By autumn, foraging tree preferences among species were much more homogeneous, especially among wood-warblers of the genus Dendroica Gray, 1842. Consequently, based on preferred foraging tree species, whatever segregation existed during breeding was largely disassembled by autumn.

Abstract:
AbstractWe measured metabolic heat production (H ˙m) of perching and foraging Black-capped Chickadees (Poecile atricapillus) to determine if the heat produced during foraging activity, or exercise thermogenesis, could replace thermoregulatory heat production requirements. H ˙m and activity of chickadees in winter were measured at ambient temperatures (Ta) ranging from −11.5° to 15.5°C. Mean activity amplitude recorded with an activity detector was significantly higher in foraging birds than perching birds. H ˙m did not vary significantly between perching and foraging birds, indicating that heat produced during foraging does substitute for heat produced by shivering for thermoregulation. Evaporative water loss and dry thermal conductance did not vary significantly between perching and foraging chickadees. These results suggest that heat produced from locomotor muscles during foraging activity substitutes for thermoregulatory requirements in glean-and-hang foraging species, such as chickadees, as well as in ground-foraging birds.

Abstract:
Abstract The sand viper Cerastes vipera can employ one of two distinct foraging modes, the widely foraging or sit-and-wait mode, depending on the interplay between external and internal factors. Here, I illustrate how tracking methods can be used to evaluate the relative usage of each of the two foraging modes by the sand viper. Foraging theory models generally refer to the time invested in foraging as the main indicator of the energy invested in foraging. I suggest that tracking and counting print marks on trails offer a more precise method of estimating foraging costs in the field. I model the benefits and costs of the viper employing each of the two foraging modes using tracking data, and discuss how it can be used to decipher its foraging mode. I present a measurement approach by which to assess the relative usage of different foraging modes. I contend that the proposed tracking methods and their analysis should prove to be equally applicable to other animals that leave print marks on sand or snow.

Abstract:
This study investigates the factors driving foraging behavior of Daubenton’s bats ( Myotis daubentonii (Kuhl, 1817)). We analysed the importance of food availability, energy demand, and intraspecific competition in regulating foraging activity and the selection of near versus distant foraging sites. At two foraging patches, insect abundance, foraging activity, and the number of foraging individuals were monitored using sticky traps, telemetry, spotlight counting, and light sticks. Population size was determined by flight path counting. General linear model analysis showed that bat distribution among foraging patches was influenced by distance to roosts, month, bat population size, and the displacement pressure exerted by competing individuals. Foraging time was influenced by food resource accessibility and individual cost/benefit ratio. From June to August, population density, intraspecific competition in foraging patches, and transfer flights between patches and day roosts were most frequent (play-off time). Our results suggest that differences in foraging activity of Daubenton’s bats are mainly driven by differential energy demand and less so by food availability. In times of high energy demand, hunting is avoided when prey are scarce. During play-off time, density spillover in near foraging patches occurs and therefore more distant patches come into use in accordance with predictions by the ideal free distribution theory.

Abstract:
The insectivorous Rufous Treecreeper Climacteris rufa has declined in abundance in the agricultural regions of southwestern Australia. Examining its foraging behaviour is fundamental to identifying important foraging resources and how landscape change (e.g., fragmentation and disturbance) may affect foraging effectiveness. We studied seasonal and landscape differences in the foraging behaviour of the treecreeper in the wheatbelt of Western Australia. Foraging data were collected in autumn and winter in a large, unfragmented landscape and in a highly modified agricultural landscape (winter only) with grazed and ungrazed woodland patches. The ground layer was the most common foraging location used by the species, although there were seasonal differences in foraging behaviour in the unfragmented landscape. In autumn, treecreepers foraged primarily on trees (56% of observations) with a shift to mostly ground foraging in winter (72-74%). The species also preferentially foraged on larger trees. Foraging behaviour differed between the two landscapes within the same season. Treecreepers foraged less on the ground in the agricultural landscape (52%), but this difference is attributed mainly to the low percentage of ground foraging in ungrazed (43%) compared to grazed (60%) patches. In winter and early spring, the ground layer is an important foraging substrate for the Rufous Treecreeper and other woodland birds. Changes to the ground layer and associated invertebrate communities through habitat disturbance (e.g., weed invasion) may be detrimental to the foraging effectiveness of ground-foraging insectivores. This is a potential contributing factor to the decline of these species in the agricultural regions of southern Australia.

Abstract:
In most long-lived animal species, juveniles survive less well than adults. A potential mechanism is inferior foraging skills but longitudinal studies that follow the development of juvenile foraging are needed to test this. We used miniaturized activity loggers to record daily foraging times of juvenile and adult European shags Phalacrocorax aristotelis from fledging to the following spring. Juveniles became independent from their parents 40 days post-fledging. They compensated for poor foraging proficiency by foraging for approximately 3 h d −1 longer than adults until constrained by day length in early November. Thereafter, juvenile foraging time tracked shortening day length up to the winter solstice, when foraging time of the two age classes converged and continued to track day length until early February. Few individuals died until midwinter and mortality peaked in January–February, with juvenile mortality (including some of the study birds) five times that of adults. In their last two weeks of life, juveniles showed a marked decline in foraging time consistent with individuals becoming moribund. Our results provide compelling evidence that juveniles compensate for poor foraging proficiency by increasing foraging time, a strategy that is limited by day length resulting in high winter mortality.

Abstract:
Alternative forms of food procurement have increased in consumer popularity since the occurrence of food price inflation and the ongoing recession in the U.S. The present study explores predictors such as food engagement, food-related COVID-19 concerns, and the importance of sustainable foraging practices as determinants for U.S. consumers’ preferences for food foraging. Two scenarios are investigated, the preference for food foraging over growing food and food foraging over regular food buying. The study is based on an online consumer survey (n = 401) and used partial least square structural equation modeling (PLS-SEM) for the data analysis. Results indicate that food engagement is the strongest predictor for both foraging over buying and foraging over growing scenarios. However, food-related COVID-19 concern appears to only be relevant for the foraging over buying scenario and the importance of sustainable growing practices is only relevant for the foraging over growing scenario. These findings are important because they indicate the attitudinal triggers of food foraging and are therefore of relevance to foraging communities and managers in municipalities, food retail, and horticultural businesses who are associated with traditional and alternative forms of food procurement.

Abstract:
Since the occurrence of COVID-19 and food price inflation, alternative forms of food procurement increased in popularity. The present study is dedicated to urban foraging and aims to explore key factors driving food foraging behavior in the U.S. Two specific foraging behaviors, namely “leaving food behind” or “taking it all”, have been investigated in a gardening and non-gardening location. Leaving food behind is crucial to sustainable foraging practices, as it allows plants and ecosystems to recover and promotes fairness in foraging communities. Data was procured from an online consumer survey and analyzed using SmartPLS 4, which allowed the use of partial least square structural equation modeling (PLS-SEM). PLS-SEM is particularly suitable for complex exploratory studies as it does not require distributional assumptions. Results indicate that nature and food attitudes predict attitudes toward urban foraging. Foraging attitudes, such as food foraging is challenging and food foraging benefits people and the planet, which are the most important drivers for taking or leaving behaviors in both types of locations. These findings are of relevance to managers in municipalities, landscape designers, horticultural businesses, and other stakeholders who create, shape, and govern landscapes used for food foraging.

Abstract:
Abstract We quantified foraging rates and foraging visibility metrics for four Neotropical warblers—Slate-throated Redstart (Myoborus miniatus), Golden-crowned Warbler (Basileuterus culicivorus), Wilson's Warbler (Wilsonia pusilla), and Black-and-White Warbler (Mniotilta varia)—under flocking and solitary conditions in western Panama to test hypotheses regarding the relative influences of predation pressure and social facilitation on foraging behavior. We also compared foraging behavior in primary forests and in traditionally managed shade coffee fields for two species (Slate-throated Redstart and Wilson's Warbler) to estimate spatial variation in foraging behavior and compare it to variation due to social situation (flocking or solitary). We then assessed the contribution of spatial variation in flocking propensity to the total spatial variation in foraging rates within species. We observed very little overall within-species variability in foraging behavior between social situations or study locations. Only Slate-throated Redstart's behavior was consistent with the hypothesis that flock membership reduces predation pressure and therefore reduces the amount of foraging time spent being vigilant against predators, allowing birds to forage more quickly and find more prey items per minute. No species' behavior supported the hypothesis that flocking birds forage more efficiently than solitary birds by obtaining useful information from flock mates about the location or suitability of foraging resources or techniques. The effort required to find prey items did not vary between study locations (forest and coffee field plots) for Wilson's Warbler. Because flocking also had no effect on foraging behavior of Wilson's Warbler, a reduction in flocking propensity in coffee habitat, relative to forest, did not cause further foraging behavior differences between study locations. Spatial variation in Slate-throated Redstart's foraging behavior independent of a flocking effect was minor; but flocking affected foraging rates, and flocking propensity was lower in coffee fields than in forest, so that location and flocking effects combined to widen foraging rate differences between locations. Thus, variations in flocking behavior and foraging behavior interacted differently for those two species.

Abstract:
Three species of Columbidae (Columbina talpacoti,Columbina picui and Zenaida auriculata) were studied in Londrina, Northern Paraná (Brazil), with the aim of analyzing which foraging and habitat factors contribute to their ecological partitioning. The study was conducted over one year in three different areas (urban, rural and pasture). We made monthly observations of the foraging strategies used by the species and the habitats they selected. Possible variations in availability of resources over the twelve months of the study did not influence the type of foraging used by the three species. Significant differences between the foraging strategies used by the species were observed in relation to the foraging site, specifically the foraging substrate. Soil, grass and paving were the foraging substrates that were most used by all three species, indicating that they are ground-foraging birds. Differences in the time spent in the foraging areas were significant between species; Z. auriculata remained in the foraging area for the longest time, often foraging in a group, suggesting a possible adaptation of this species in order to obtain a greater amount of resources. Adapting to anthropological environments without continuous forest cover could be one of factors that the most influential in the selection of habitat by the three species of Columbidae. Principal Components Analysis (PCA) showed differences between the proportions of herbaceous and gramineae plants, paving, plantations and shrubs in the habitats selected by each species. We also concluded that differences in the time spent in the foraging areas and between foraging substrates are factors contributing to the ecological separation of the three species and therefore allowing their coexistence in the region.

Abstract:
Over 50 000 individual dive records collected by time-depth recorders were analysed with respect to sex of the seal, time of year and the approximate geographic location of the dive. Six distinct dive types were described on the basis of parameters such as the amount of time spent at the maximum depth of the dive, the rate of ascent and descent, and the general form of the dive profile. These dive types were 'rest' dives, 'travel' dives, 'surface' dives, 'general non-foraging' dives, 'pelagic foraging' dives and 'benthic foraging' dives. The seals spent 90% of their time at sea submerged. Less than 2% of the time was spent on the surface in intervals of more than 10 min. A further 20-30% of the time was spent on the various non-foraging types of dives. Most females performed only 'pelagic foraging' dives, while males performed both 'pelagic' and 'benthic foraging' dives. All the 'benthic foraging' dives occurred in Area 3 (defined by water-temperature data as lying over the Antarctic Continental Shelf) and were 400-500 m deep. 'Pelagic foraging' dives occurred in all three foraging areas and ranged in depth from 200 to 1100 m. These types of dives also exhibited marked diurnal variations in depth, unlike 'benthic foraging' dives. The seals spent 10-20 min at the bottom of each 'foraging' dive, where they generally displayed a series of small changes in depth (wiggles). The size of these 'wiggles' tended to be larger in 'pelagic foraging' dives than in 'benthic foraging' dives. The diving behaviour of southern elephant seals is related to the possible prey they exploit in the Southern Ocean.

Abstract:
People and other animals can search for information inside their heads. Where does this ability come from, and what does it enable cognitive systems to do? In this article, we address the behavioral and cognitive similarities between search in external environments and internal environments (e.g., memory). These require both maplike representations and the means to navigate them, and the latter involves modulation between exploitation and exploration analogous to a foraging process called area-restricted search. These findings have implications for understanding a number of cognitive abilities commonly considered to be hallmarks of the human species, such as well-developed executive control and goal-directed cognition, autonoetic consciousness (i.e., self-awareness), deliberation, and free will. Moreover, this research extends our conception of what organisms may share these abilities and how they evolved.
