Diurnal Activity Profiles of Forest-inhabiting Indian Peafowl in Bornadi Wildlife Sanctuary, Assam, India

A free-ranging flock of Indian Peafowl (Pavo cristatus) was studied to analyze their diurnal activity budget in Barnodi Wildlife Sanctuary, Assam, India. A total of 11,664 scan samples were collected over three consecutive years (2021-22 to 2023-24), covering all four distinct seasons. The study revealed that feeding was the predominant activity, impacting all other behaviors throughout the day. Bimodal peaks for feeding (up to 58% during the morning and 60% during the afternoon) and locomotion activities (up to 20% during the morning and 41% during the afternoon) while a mid-day peak for resting was observed. Additionally, mid-day peaks were noted for both preening and sand-basking behaviors. Display activity was more frequent during late morning and midday, further supporting its social function, which appeared to be balanced with resting time. However, the relatively consistent monitoring behavior suggested a typical approach to territory defense and predator safety. The findings also indicate that the random distribution of food resources influences the diurnal activity budget of forest-dwelling Indian Peafowl.

Water-Energy-Food Communities in South Africa: Exploring Multi-Actor Governance Instruments Contributing to Social Justice

Abstract South Africa faces significant challenges concerning the scarcity and unequal distribution of water, energy and food resources. The Constitution of the Republic of South Africa, 1996 underscores the importance of social justice and mandates collaboration among all levels of government and state entities. To effectively address the interconnected nature of these resources, a collaborative governance approach is necessary. This article introduces the concept of ‘Water-Energy-Food (wef) communities’, a concept not currently recognised in South African law, drawing inspiration from the European Union’s Renewable Energy Directive (res-Directive) of 2018 and the Electricity Market Directive (E-Directive) of 2019 that introduced the concept of ‘energy communities’. wef communities, operating at the local level, could integrate improved governance and decision-making in the water, energy, and food sectors, thereby advancing social justice in local communities. The article compares existing multi-actor governance instruments in South African law and uses the EU law as learning points for the establishment of wef communities as opposed to energy communities that focus on one determinant only. Although the current South African multi-actor governance instruments do not explicitly address an integrated wef governance approach, they may serve as a basis for proposing framework rules to establish wef communities, highlighting their potential to achieve social justice goals in relation to their access to water, energy and food. The article proposes rules for the potential establishment of wef communities, taking learning points from the EU directives as well as existing South African instruments.

Evaluating effects of natural and anthropogenic factors on American black bear occupancy in northern Georgia, USA

AbstractAlthough previously close to extirpation in the southeastern United States, American black bear (Ursus americanus) abundance and distribution have increased with habitat management and harvest regulation. The north Georgia black bear population, the most abundant and widely distributed in the state, is currently being exposed to pressures from increasing anthropogenic disturbances, such as recreation and vehicle traffic. We evaluated the effects of environmental factors and anthropogenic activity on habitat use of black bears within a wildlife management area open to public recreation. We used detection/non‐detection data from camera surveys conducted at 448 locations from April to December 2023 to fit hierarchical single‐species occupancy models. Black bear detection was best explained by Julian date, its quadratic effect, and weekly human activity index. Detection increased through the spring, peaked in June, and declined throughout late summer and fall. In contrast to detection, occupancy was not affected by seasonal differences in black bear activity. Occupancy increased with increasing elevation, distance to water, and distance to high‐use recreation areas. The spatial distribution of food resources likely contributed to the observed black bear occupancy pattern related to elevation and distance to water, while human disturbance in the study area also influenced black bear occupancy. Thus, our results suggest that in a landscape open to public recreation, black bear occupancy was driven by a combination of environmental and anthropogenic factors. Identifying patterns of occupancy at a scale typical of management provides important information for managing black bear populations throughout the large, connected network of national forests in the Appalachian region.

Enhancing Agriculture through AloT and Data Analytics Middleware

Middleware in Agriculture delves into the data analytics role of systematic Artificial Intelligence of Things (AIoT) in convergence agriculture with smart farming. AIoT devices, remote diagnostic data analytics platforms, data analytics, formal recognition, and vision learning have generated both the amount and nature of work in rural areas. The reason for the developing changes in the global population by age is the bias in the distribution of food resources, as well as changes in climate change and the soil condition of compost. Data scientists are soon attempting to dive convergence Internet of Things (IoT) advances in savvy cultivating to support ranchers in producing better seeds, crop assurance, and manures utilizing AIoT convergence technology[1]. This distinguishes consumer-provider-administrator as a service subscriber roleon the platform, which goes for earning the nation's economy and the profitability of ranchers. The central regions where AIoT begins to emerge are agricultural robots, scrutiny, and soil and yield observation. While middleware technology for data analysis is applied, there is a great advantage of analyzing regional observation data at a real-time level. Based on this analysis method, it will spread to high-tech industries connected to production, processing, and consumption, which are subdivided areas of each precision agriculture. In this sense, ranchers are utilizing sensors for data analysis and soil information in a detailed way to gather a model that the executives dynamic platforms might use for further examination. Through an outline of real-time data analytics AIoT applications in the farming convergence industry, this paper tries a trust data basement forecast to the farming protocols[2]. It starts with a roadmap to the AIoT and an investigation of real-time data strategies utilized in the horticultural industry data analytics using Universal Middleware, service platforms, vision learning, and dynamic statistics. This study advances a dynamic platform examination of the literature on data resources and how AIoT is utilized in farming convergence. This study looked at the unstructured systems of modern agriculture, divided these processes into devices and services, and presented a systematic formalization model. It should contribute to the integration of segmented data connectivity in the AIoT field. The enhanced research model contributes to the discovery of numerous untapped additional services between devices and services.

Monkey menace in Nepal: An analysis and proposed solutions

Monkey menace is a prevalent issue in South Asia and Southeast Asia, where Rhesus macaques are considered pests of major field crops. In Nepal, factors such as monoculture cropping patterns, forest fragmentation, degradation of natural habitats, and changing agricultural practices contribute to increased monkey menace and human-macaque conflict. Factors such as cropping season, food resource distribution, crop variety, wild food availability, and distance from forests and farms influence the frequency and intensity of crop raiding. This study introduced non-human primates, their status, and availability in Nepal, and analyzed different crops raided by monkeys along the Buddhi Gandaki River, frequency and crop raiding season of monkeys in Jhor Mahankal and Goldhunga and suggested some solution measures for the monkey menace in Nepal. Maize was the most raided crop, while pumpkin was the least. The total percentage of crops raided was 24.62%, with an average crop loss of 29.24%. Crop raiding was most prevalent during the spring season (45%), followed by the rainy season (39%), and least prevalent during the winter season (16%). Rhesus macaques refrained from raiding crops with bitter or spicy flavors, such as turmeric, bitter gourd, chili, ginger, and mustard. The suggested control measures need to be followed to mitigate the monkey menace and manage the human-wildlife conflict.

To move or not to move: Dispersal of Orius insidiosus in strawberry plants

AbstractSpatial and temporal distribution of food resources influences predatory insects' foraging and dispersal behavior. Orius insidiosus (Say) (Hemiptera: Anthocoridae) is a good biological control agent of western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), in the strawberry crop and consumes two‐spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), and pollen as well. Augmentative biological control programs may fail if, following release, predators disperse from the crop. We studied the dispersal of O. insidiosus as a function of pollen availability, density of their main prey WFT, and the presence of the alternative prey TSSM, within and between strawberry plants. We found that O. insidiosus remained on the flowers during the 24 h of the assay. The dispersal of predators to a neighboring flower with thrips was approximately six times greater from a flower without pollen than from a flower with pollen. When TSSM was the only prey available, O. insidiosus colonized the leaves, and its dispersal within the plant was greater. At the plot scale, the predator dispersal from the release plant to other plants also depended on the presence of flowering plants and prey. Our results highlight the importance of flowering plants and pollen availability in enhancing the persistence of O. insidiosus in strawberry plants. Releases of this predator in the strawberry crop should be after the beginning of flowering, even at low WFT densities.

Inferring mode of acquisition from lithic conveyance: A pesky middle-range problem

Inferring mode of acquisition from lithic conveyance is a long-standing middle-range problem. Given archaeologists’ reliance on patterns of lithic conveyance to understand how prehistoric populations organized themselves in relation to their landscape, its resources, and each other, resolution of this problem would be significant. Drawing on research in the North American Great Basin and Middle Atlantic, we argue that the concepts archaeologists often use to derive insight into landscape use and sociocultural organization from patterns of lithic conveyance warrant greater scrutiny. We argue that archaeologists may better be able to infer landscape use and sociocultural organization from patterns of lithic conveyance if we remember that our conceptions (e.g., residential and logistical mobility, direct and indirect procurement, embedded and “dis”embedded procurement) sit in physical and social space – landscapes characterized by the distribution of food and nonfood resources (including stone), as well as other people.

Nutritional Factors Associated with Dental Caries across the Lifespan: A Review

Nutrition and dietetic care span various life stages, addressing nutritional needs and exploring factors that shape dietary habits. Globally, an alarming disproportion in food resource distribution, coupled with substandard nutritional intake, underscores profound implications for oral health. This is evident in the facilitation of dental caries development and its repercussions on oral soft tissue integrity. While modern markets offer advanced edible products, their effects on oral health, especially in relation to dental caries, remain uncharted. This narrative literature review pursues a four-fold objective: (a) scrutinizing the repercussions of inadequate nutrition on dental caries, (b) exploring psychological determinants influencing dietary habits contributing to caries development, (c) investigating potential implications of newly devised food products on caries formation, and (d) elucidating the role of dentists as facilitators in promoting oral health practices. A comprehensive search spanning PubMed, Web of Science, and Cochrane Library yielded 46 cohort, cross-sectional research articles and systematic reviews adhering to standardized diagnostic criteria for dental caries evaluation. The results highlight contemporary lifestyles as potent contributors to heightened risk of caries due to suboptimal nutritional quality and nutrient insufficiency. Additionally, concerns have arisen with the advent of synthetically engineered food products, warranting exploration of potential implications for future caries development and global oral health status. This review emphasizes the pivotal role of dietitians–nutritionists and dental professionals in advocating sound nutritional practices specifically geared towards preventing dental caries. Ultimately, this review contributes to the understanding of the intricate interplay between nutrition, oral health, and the imperative role of healthcare professionals in fostering preventive measures.

Characterisation of Antennal Sensilla and Electroantennography Responses of the Dung Beetles Bubas bison, Onitis aygulus and Geotrupes spiniger (Coleoptera: Scarabaeoidea) to Dung Volatile Organic Compounds.

Locating sporadically distributed food resources and mate finding are strongly aided by volatile cues for most insects, including dung beetles. However, there is limited information on the olfactory ecology of dung beetles. We conducted a scanning electron microscopy study on the morphology and distribution of the antennal sensilla of three introduced dung beetle species in Australia: Geotrupes spiniger (Coleoptera: Geotrupidae), Bubas bison and Onitis aygulus (Coleoptera: Scarabaeidae). Three main morphological types of antennal sensilla were identified: sensilla trichodea (ST), sensilla basiconica (SB) and sensilla chaetica (SCh). Distinct variations of SB distribution were observed in B. bison and G. spiniger and on different lamellar surfaces in both sexes of all three species. Sexual dimorphism in antennal sensilla distribution or their abundance was not evident. To complement the morphological characterisation of sensilla, electroantennography (EAG) was carried out to construct EAG response profiles of the three species to selected dung volatiles. An initial study revealed that antennae of all species were sensitive to a mix of phenol, skatole, indole, p-cresol, butanone and butyric acid, common components of livestock dung headspace. In addition to these six compounds, dimethyl sulfide, dimethyl disulfide, eucalyptol and toluene were tested for antennal activity. All compounds evoked measurable EAG responses, confirming antennal sensitivity. Geotrupes spiniger exhibited significant responses to all the compounds compared to the control, whereas B. bison and O. aygulus only responded to a subset of compounds. A comparison of relative EAG amplitudes revealed highly significant responses to p-cresol in G. spiniger and to skatole in B. bison. Geotrupes spiniger displayed differential responses to all the compounds. Pooled EAG data suggest highly significant differences in responses among the three species and among compounds. Our findings suggest that a blend of volatiles may offer potential for the trapping of dung beetles, thereby avoiding the use of dung baits that are inconvenient, inconsistent and may pose a threat to farm biosecurity.

Monitoring of hive weight changes in various landscapes

Bee development is determined by the quantity and quality of food resources available in the environment that can be used by bees only to a certain extent. Therefore, this study aimed to evaluate, by means of changes in hive weight, the amount of food collected by honey bees in various landscapes, in relation to meteorological conditions, landscape, and forest structure. The monitored colonies (n = 104) were placed on electronic beehive scales, which provided data about hive weight, temperature, and humidity over two beekeeping seasons. The landscape valuation within a 2 km radius from each beehive was prepared based on digital maps. The seasonal distribution of food resources collected by honey bees was determined based on hive weight changes analysed in 5-day-periods (i.e. pentads). The hive weight changes mainly depended on the observation period and the air temperature. The hive weight increased from April to the last 10 days of June and when the air temperature was over 24 °C. The proportions of agricultural lands and forests, as well as the air humidity, had a small effect on hive weight changes. Continuous monitoring of the weight of honey bee colonies on a large scale showed that honey bees collected food stores in their nests mainly in the spring. Then, they collected a small amount of food, probably due to limited access to food resources from the last 10 days of June until the end of the growing season.

Hindu-Right Activism in Pandemic: Exploring the Role of Durga Vahini in Covid-19

Women’s activism in the Hindu right has gone through communication and mobilisation shifts in the context of Covid-19. The article traces how the hierarchy and coordination within the Durga Vahini—the women’s wing of the Vishwa Hindu Parishad facilitate the propagation of two primary goals 1 of seva, and sanskar in Delhi and Uttar Pradesh. Through semi-structured interviews with the representatives of the organisation, the article focuses on understanding mobilisation strategies like e- satsangs, accommodation of marginalised groups through the distribution of raw food resources, and manipulation of mythological narratives for the recruitment of young girls to propagate Hindu nationalism. The core argument of the article is focused on understanding these mobilisation tactics and changing nature seva in the times of pandemic.

Extreme El Niño southern oscillation conditions have contrasting effects on the body condition of five euphausiid species around the northern Antarctic Peninsula during winter

El Niño southern oscillation (ENSO) events drive profound global impacts on marine environments. These events may result in contrasting conditions in the Southern Ocean, with differing effects on euphausiid species because of their diverse life histories, habitats, and feeding ecologies. We conducted oceanographic surveys during winter (2012–2016) around the northern Antarctic Peninsula and examined the dietary carbon sources, trophic position, and body condition of five euphausiid species (Euphausia crystallorophias, E. frigida, E. superba post-larvae and larvae, E. triacantha, and Thysanoessa macrura) in relation to environmental conditions each year. In addition to general patterns among taxa, we focused on how contrasting conditions during an ENSO-neutral year (2014) and an ENSO-positive year (2016) affected the type, quality, and distribution of food resources each year, as well as the body condition of each species. We observed high chlorophyll-a, low salinity, and shallow upper mixed-layer depths in 2014, and low chlorophyll-a, high salinity, and deep upper mixed-layer depths in 2016. Carbon sources varied among years, with most species enriched in δ13C when ENSO conditions were dominant. Trophic position and body condition also varied among years, with different responses among species depending on conditions; inter-annual variation in δ15N was minimal, while E. triacantha was the only species with notably lower body condition in 2016. We conclude that ENSO conditions around the northern Antarctic Peninsula may result in a more favorable feeding environment for all euphausiid species except E. triacantha, which may be the most negatively impacted by the predicted increase in ENSO conditions.

Not all dung beetles feed on dung: Scarabaeinae (Coleoptera: Scarabaeidae) attracted to different carrion types in contrasting habitats at Brazilian Amazon

AbstractBy understanding how assemblages segregate according to food types, it is possible to depict and understand species distribution and exploitation of similar food resources. Although it is well known that dung beetles may feed on carrion, but the attractiveness of different carrion types for these beetles is still poorly understood. In this study, we compared the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) diversity attracted to two carrion types in different habitats in an Amazonian landscape. Dung beetles were captured by using pitfall traps baited with decaying cattle beef and cattle liver in native forest, peach palm plantation, teak plantation and exotic pasture. Overall, we captured 582 dung beetles of 43 species, where Canthidium aff. lentum was classified as a specialist of cattle beef, Deltochilum sp. One was considered specialist of liver carrion, 11 were considered generalists and for the 30 remaining species, it was not possible to determine their carrion preference due to the low number. Abundance, but not species richness, was affected by carrion type, and a higher number of beetles was recorded in beef‐baited traps compared to liver‐baited traps. According to functional groups, endocoprid beetles were more abundant in traps baited with decaying beef, while paracoprid and telecoprid beetles did not show preference for any carrion type. This study suggests a novel scenario of intra‐resource segregation, where species vary their preferences depending to the part of the dead corpse being exploited. The amount of food resource, the maintenance of stable populations and trophic preference mediated by chemical cues are some mechanisms that may explain the segregation of dung beetles among carrion types.

Nutrient balancing in a fruit‐specialist primate, the black‐and‐white ruffed lemur (Varecia variegata)

Animals' foraging behavior and dietary choices are, in part, driven by their ultimate function: to meet nutritional demands. However, depending on their degree of dietary specialization and the availability and distribution of food resources in their environment, species may utilize different nutritional strategies. With shifting plant phenology, increasing unpredictability of fruiting, and declining food quality in response to anthropogenic climate change, existing nutritional constraints may become exacerbated. Such changes are especially concerning for Madagascar's endemic fruit specialists given the nutrient-limitation of the island's landscapes. In this study, we examined the nutritional strategy of one such fruit-specialist primate, the black-and-white ruffed lemur (Varecia variegata), over a 12-month period (January to December 2018) in Ranomafana National Park, Madagascar. We hypothesized that Varecia would balance nonprotein energy (NPE) to protein (AP) at a high ratio similar toother frugivorous primates, and that they would prioritize protein intake given their high degree of frugivory. We found that Varecia balance NPE:AP at a ratio of 11:1, higher than in any other primate studied to date; however, diets shifted such that nutrient balancing varied seasonally (12.6:1 abundant-9.6:1 lean). Varecia meet NRC suggested recommendations of 5-8% of calories from protein, despite having a diet mostly comprising fruits. However, seasonal shifts in NPE intakes result in significant energy shortfalls during fruit-lean seasons. Flowers provide an important source of NPE during these periods, with flower consumption best predicting lipid intake, suggesting this species' ability to shift resource use. Nevertheless, achieving adequate and balanced nutrient intakes may become precarious in the face of increasing unpredictability in plant phenology and other environmental stochasticities resulting from climate change.

Biotic resistance to fish invasions in southern China: Evidence from biomass, habitat, and fertility limitation.

Understanding the mechanisms underlying the invasion success or failure of alien species can help to predict future invasions and cope with the invaders. The biotic resistance hypothesis posits that diverse communities are more resistant to invasion. While many studies have examined this hypothesis, the majority of them have focused on the relationship between alien and native species richness in plant communities, and results have often been inconsistent. In southern China, many rivers have been invaded by alien fish species, providing an opportunity to test the resistance of native fish communities to alien fish invasions. Using survey data for 60,155 freshwater fish collected from five main rivers of southern China for 3 years, we assessed the relationships between native fish richness and the richness and biomass of alien fishes at river and reach spatial scales, respectively. Based on two manipulative experiments, we further examined the impact of native fish richness on habitat selection and the reproductive ability of an exotic model species Coptodon zillii. We found no apparent relationship between alien and native fish richness, whereas the biomass of alien fish significantly decreased with increasing native fish richness. In experiments, C. zillii preferred to invade those habitats that had low native fish richness, given evenly distributed food resources; reproduction of C. zillii was strongly depressed by a native carnivorous fish Channa maculata. Together, our results indicate that native fish diversity can continue to provide biotic resistance to alien fish species in terms of limiting their growth, habitat selection, and reproduction when these aliens have successfully invaded southern China. We thus advocate for fish biodiversity conservation, especially for key species, to mitigate against the population development and ecological impact of alien fish species.

Russia and the Modern Food Crisis: Political and Economic Retrospective

Currently, a large-scale food crisis is unfolding in the world, due to a number of exogenous and endogenous factors. Being an integral part of the emerging new socio-economic reality, this crisis is not only global, but also diversified, affecting many sectors not only of agriculture, but also of industry (food industry, fertilizer production, chemical industry, etc.), exerting its influence and on the state of food security of the Russian Federation. In this regard, an analysis of the causes, nature and possible consequences of this crisis is not only of considerable theoretical, but also quite practical interest. In this regard, the purpose of the study is to assess the nature, nature, dynamics, characteristics and consequences of the development of the global food crisis and its impact on the food security of the Russian Federation, as well as ways to prevent it. The main causes of the modern world food crisis are revealed. The difference between the current food crisis and other similar crises associated with the growing uneven socio-economic development of different regions of the world and the depletion of natural, primarily biological resources, has been identified and argued. The specificity of the food crisis is shown, due to a certain extent to the multiplicative effect of destructive processes in the production and distribution of food resources, miscalculations in the economic, environmental and social policies of individual states. The possible consequences of the food crisis are determined. Additional ways and mechanisms to prevent the food crisis in the territory of the Russian Federation are argued. The article substantiates the position that along with the quantitative aspects of food policy associated with increasing the volume of food production and import substitution, a special role in the conditions of macroeconomic instability and uncertainty is acquired by qualitative aspects, primarily the quality, nutritional value and safety of food itself, its economic accessibility, timeliness and completeness of food supply.

Evaluating the efficacy of a consumer-centric method for ecological sampling: Using bonobo (Pan paniscus) feeding patterns as an instrument for tropical forest characterization.

Characteristics of food availability and distribution are key components of a species' ecology. Objective ecological surveying used in animal behavior research does not consider aspects of selection by the consumer and therefore may produce imprecise measures of availability. We propose a method to integrate ecological sampling of an animal's environment into existing behavioral data collection systems by using the consumer as the surveyor. Here, we evaluate the consumer-centric method (CCM) of assessing resource availability for its ability to measure food resource abundance, distribution, and dispersion. This method catalogs feeding locations observed during behavioral observation and uses aggregated data to characterize these ecological metrics. We evaluated the CCM relative to traditional vegetation plot surveying using accumulated feeding locations across 3 years visited by a tropical frugivore, the bonobo (Pan paniscus), and compared it with data derived from over 200 vegetation plots across their 50 km2+ home ranges. We demonstrate that food species abundance estimates derived from the CCM are comparable to those derived from traditional vegetation plot sampling in less than 2 years of data collection, and agreement improved when accounting for aspects of consumer selectivity in objective vegetation plot sampling (e.g., tree size minima). Density correlated between CCM and plot-derived estimates and was relatively insensitive to home range inclusion and other species characteristics, however, it was sensitive to sampling frequency. Agreement between the methods in relative distribution of resources performed better across species than expected by chance, although measures of dispersion correlated poorly. Once tested in other systems, the CCM may provide a robust measure of food availability for use in relative food availability indices and can be incorporated into existing observational data collection. The CCM has an advantage over traditional sampling methods as it incorporates sampling biases relevant to the consumer, thereby serving as a promising method for animal behavioral research.

Emergency food distribution efforts in New Orleans, LA after Hurricane Ida.

BackgroundThe provision of food aid after a natural disaster is necessary to prevent hunger, particularly in low-resourced and low-income communities. Little is known about the operational challenges associated with ensuring equitable distribution of emergency food resources to communities in need following a disaster. To address this gap, this study assessed emergency food distribution efforts in New Orleans, LA during the 2 weeks following Hurricane Ida's landfall on August 29, 2021.MethodsInformation on free food distribution events was gathered from online sources. A list of distribution sites was generated that included data on operational logistics (e.g., address, days of operation, hours of operation, etc.), food offerings (e.g., prepared meals, groceries, etc.), and socio-demographic characteristics of the surrounding community. Geospatial mapping and bivariate analyses were used to analyze the site data.ResultsSeventy-four distribution sites operated in the 2 weeks after Hurricane Ida. Approximately 47.3% were located in census tracts with >80% Black residents, and 39.2% were in tracts with >30% poverty. A large proportion of sites offered prepared meals (86.2%) and only operated 1 day (36.5%). Tracts with >80% Black residents had more sites that operated only 1 day (p = 0.04). Tracts with >30% poverty had more sites that started distributing food resources 7–15 days after the hurricane (p = 0.02).ConclusionsMost low-income and low-resourced communities in New Orleans had access to emergency food resources; however, several limitations in operations were identified that may have influenced access. Future initiatives to prevent hunger after a natural disaster in New Orleans, and elsewhere, should improve operational logistics for food aid.

Habitat use by female desert tortoises suggests tradeoffs between resource use and risk avoidance.

Animals may select habitat to maximize the benefits of foraging on growth and reproduction, while balancing competing factors like the risk of predation or mortality from other sources. Variation in the distribution of food resources may lead animals to forage at times or in places that carry greater predation risk, with individuals in poor quality habitats expected to take greater risks while foraging. We studied Mojave desert tortoises (Gopherus agassizii) in habitats with variable forage availability to determine if risk aversion in their selection of habitat relative was related to abundance of forage. As a measure of risk, we examined tortoise surface activity and mortality. We also compared tortoise body size and body condition between habitats with ample forage plants and those with less forage plants. Tortoises from low forage habitats selected areas where more annual plants were nutritious herbaceous flowering plants but did not favor areas of greater perennial shrub cover that could shelter them or their burrows. In contrast, tortoises occupying high forage habitats showed no preference for forage characteristics, but used burrows associated with more abundant and larger perennial shrubs. Tortoises in high forage habitats were larger and active above ground more often but did not have better body condition. Mortality was four times higher for females occupying low forage habitat than those in high forage habitat. Our results are consistent with the idea that tortoises may minimize mortality risk where food resources are high, but may accept some tradeoff of greater mortality risk in order to forage optimally when food resources are limiting.
