Climatic and environmental patterns associated with hantavirus pulmonary syndrome, Four Corners region, United States. (1/2152)

To investigate climatic, spatial, temporal, and environmental patterns associated with hantavirus pulmonary syndrome (HPS) cases in the Four Corners region, we collected exposure site data for HPS cases that occurred in 1993 to 1995. Cases clustered seasonally and temporally by biome type and geographic location, and exposure sites were most often found in pinyon-juniper woodlands, grasslands, and Great Basin desert scrub lands, at elevations of 1,800 m to 2,500 m. Environmental factors (e.g., the dramatic increase in precipitation associated with the 1992 to 1993 El Nino) may indirectly increase the risk for Sin Nombre virus exposure and therefore may be of value in designing disease prevention campaigns.  (+info)

Long-term studies of hantavirus reservoir populations in the southwestern United States: rationale, potential, and methods. (2/2152)

Hantaviruses are rodent-borne zoonotic agents that cause hemorrhagic fever with renal syndrome in Asia and Europe and hantavirus pulmonary syndrome (HPS) in North and South America. The epidemiology of human diseases caused by these viruses is tied to the ecology of the rodent hosts, and effective control and prevention relies on a through understanding of host ecology. After the 1993 HPS outbreak in the southwestern United States, the Centers for Disease Control and Prevention initiated long-term studies of the temporal dynamics of hantavirus infection in host populations. These studies, which used mark-recapture techniques on 24 trapping webs at nine sites in the southwestern United States, were designed to monitor changes in reservoir population densities and in the prevalence and incidence of infection; quantify environmental factors associated with these changes; and when linked to surveillance databases for HPS, lead to predictive models of human risk to be used in the design and implementation of control and prevention measures for human hantavirus disease.  (+info)

Long-term studies of hantavirus reservoir populations in the southwestern United States: a synthesis. (3/2152)

A series of intensive, longitudinal, mark-recapture studies of hantavirus infection dynamics in reservoir populations in the southwestern United States indicates consistent patterns as well as important differences among sites and host-virus associations. All studies found a higher prevalence of infection in older (particularly male) mice; one study associated wounds with seropositivity. These findings are consistent with horizontal transmission and transmission through fighting between adult male rodents. Despite very low rodent densities at some sites, low-level hantavirus infection continued, perhaps because of persistent infection in a few long-lived rodents or periodic reintroduction of virus from neighboring populations. Prevalence of hantavirus antibody showed seasonal and multiyear patterns that suggested a delayed density-dependent relationship between prevalence and population density. Clear differences in population dynamics and patterns of infection among sites, sampling periods, and host species underscore the importance of replication and continuity of long-term reservoir studies. Nevertheless, the measurable associations between environmental variables, reservoir population density, rates of virus transmission, and prevalence of infection in host populations may improve our capacity to model processes influencing infection and predict increased risk for hantavirus transmission to humans.  (+info)

Suppression of giardiasis during the intestinal phase of trichinosis in the mouse. (4/2152)

The interaction of the intestinal phases of Giardia muris and Trichinella spiralis was investigated in Swiss albino mice. Intraoesophageal inoculation of G. muris cysts seven days before, or seven days after, similar inoculation of T. spiralis larvae resulted in significant reduction in the numbers of Giardia trophozoites in small bowel and Giardia cysts in stools. This effect was not observed when G. muris cysts were administered after resolution of the intestinal phase of trichinosis. Giardiasis had no effect on trichinosis as assessed by numbers of adult worms in small bowel and larvae in skeletal muscles. Studies of small bowel morphology showed that the intestinal phase of trichinosis was associated with increased numbers of inflammatory cells in the lamina propria, a significant increase in Paneth cells in crypts, and a marked reduction in the villus:crypt ratio of jejunum. These observations suggest that the intestinal phase of trichinosis induced environmental changes in small bowel, perhaps related to inflammation, which resulted in suppression of proliferation of Giardia trophozoites.  (+info)

Protective effect of breastfeeding: an ecologic study of Haemophilus influenzae meningitis and breastfeeding in a Swedish population. (5/2152)

BACKGROUND: In Orebro County, Sweden, a 2.5-fold increase in the incidence of Haemophilus influenzae (HI) meningitis was found between 1970 and 1980. In a case-control study of possible risk factors for invasive HI infection conducted in the same area, 1987-1992, breastfeeding was found to be a strong protective factor. MATERIAL AND METHODS: In order to study the relation between incidence rates of HI meningitis between 1956-1992 and breastfeeding rates in the population an ecologic study was performed. RESULTS: A strong (negative) correlation between breastfeeding and incidence of HI infection 5 to 10 years later (rho(xy) (s) approximately -0.6) was seen, whereas no relation seems to exist for the time lag 15 years and beyond. The correlation for contemporary data was intermediate. There were similar results for the breastfeeding proportions at 2, 4 as well as 6 months of age. DISCUSSION: Our ecologic data are consistent with results from our case-control study. The time-lag for the delayed effect on the population level could be estimated although sparse data make the estimates vulnerable to sampling fluctuations. Limitations with ecologic studies are discussed. CONCLUSION: There seems to be an association between high breastfeeding rate in the population and a reduced incidence of HI meningitis 5 to 10 years later. These results do have implications on strategies for breastfeeding promotion, especially in countries where Hib vaccination is too costly and not yet implemented.  (+info)

Towards a kala azar risk map for Sudan: mapping the potential distribution of Phlebotomus orientalis using digital data of environmental variables. (6/2152)

The need to define the geographical distribution of Phlebotomus orientalis results from its importance as the dominant vector of kala azar (visceral Iceishmaniasis) in Sudan. Recent epidermics of this disease in southern and eastern Sudan caused an estimated 100000 deaths and have renewed the impetus for defining the ecological boundaries of the vector. This information is an essential prerequisite to the production of a risk map for kala azar. This study uses data on the presence and absence of P. orientalis from 44 collecting sites across the central belt of Sudan. A logistic regression model was used to estimate the probability of the presence of P. orientalis at each collecting site as a function of climatic and environmental variables (rainfall; temperature; altitude; soil type and the satellite-derived environmental proxies - Normalized Difference Vegetation Index and Land Surface Temperature). The logistic regression model indicates mean annual maximum daily temperature and soil type as the most important ecological determinants of P. orientalis distribution. An initial risk map was created in a raster-based geographical information system which delineates the area where P. orientalis may occur. This map was then refined using a mask layer indicating the known rainfall-based boundaries of the distribution of Acacia-Balanites woodland - a woodland type known to be associated with the distribution of this vector. The predictive performance of the risk map is discussed.  (+info)

A theoretical and empirical investigation of the invasion dynamics of colicinogeny. (7/2152)

A mathematical model describing the dynamics of a colicinogenic and a colicin-sensitive population propagated under serial transfer culture conditions was formulated. In addition, a series of in vitro invasion experiments using six representatives of the E colicin group was undertaken, together with the estimation of the growth rates and colicinogenic characteristics of the strains. Growth rates among the strains varied by up to 44%. There were 14-fold differences among strains in their lysis rates and there were up to 10-fold differences in the amount of colicin produced per lysed cell. The in vitro serial transfer invasion experiments revealed that regardless of initial frequency all colicinogenic strains succeeded in displacing the sensitive cell populations. The amount of time required for the colicin-sensitive cell population to be displaced declined as the initial frequency of the colicinogenic population increased and strains producing higher titres of colicin tended to displace the sensitive strain more rapidly. Overall, the observed dynamics of the invasion of colicinogenic strains was adequately described by the theoretical model. However, despite there being substantial differences among the strains in their growth rates and colicinogenic characteristics there were relatively few differences, observed or predicted, in the invasion dynamics of the six colicinogenic strains. These results suggest that the characteristics of different colicinogenic strains cannot be used to explain the extensive variation in the relative abundance of different colicins in natural populations of bacteria.  (+info)

Selected phenolic compounds in cultivated plants: ecologic functions, health implications, and modulation by pesticides. (8/2152)

Phenolic compounds are widely distributed in the plant kingdom. Plant tissues may contain up to several grams per kilogram. External stimuli such as microbial infections, ultraviolet radiation, and chemical stressors induce their synthesis. The phenolic compounds resveratrol, flavonoids, and furanocoumarins have many ecologic functions and affect human health. Ecologic functions include defense against microbial pathogens and herbivorous animals. Phenolic compounds may have both beneficial and toxic effects on human health. Effects on low-density lipoproteins and aggregation of platelets are beneficial because they reduce the risk of coronary heart disease. Mutagenic, cancerogenic, and phototoxic effects are risk factors of human health. The synthesis of phenolic compounds in plants can be modulated by the application of herbicides and, to a lesser extent, insecticides and fungicides. The effects on ecosystem functioning and human health are complex and cannot be predicted with great certainty. The consequences of the combined natural and pesticide-induced modulating effects for ecologic functions and human health should be further evaluated.  (+info)

May we Hindus and Christians, together with people of all religious traditions and good will, always foster a culture which promotes human ecology: this was the theme of the message sent by the Pontifical Council for Interreligious Dialogue to Hindus for the Feast of Deepavali, which is celebrated on 11 November. His Holiness Pope Francis, the message states, in his Encyclical Letter Laudato Si, has recently addressed the environmental and human ecological crisis threatening our planet. Thus we deem it opportune to share, in keeping with our cherished tradition, some thoughts on the need to promote human ecology, and to foster a rediscovery of the interconnectedness of creation. Human ecology points to the relationship and responsibility which humans have towards the earth and to the cultivation of ecological virtues. These virtues include a sustainable use of the earths resources through the adoption of policies, at national and international levels, which respect the interconnectedness ...
Public health promotes an ecological approach to chronic disease prevention, however, little research has been conducted to assess the integration of an ecological approach in community-based prevention programs. This study sought to contribute to the evidence base by assessing the extent to which an ecological approach was integrated into an Aboriginal community-based cardiovascular disease (CVD) and type 2 diabetes prevention program, across three-intervention years. Activity implementation forms were completed by interview with implementers and participant observation across three intervention years. A standardised ecological coding procedure was applied to assess participant recruitment settings, intervention targets, intervention strategy types, extent of ecologicalness and organisational partnering. Inter-rater reliability for two coders was assessed at Kappa = 0.76 (p | .0.001), 95% CI (0.58, 0.94). 215 activities were implemented across three intervention years by the health program (HP) with

Exploration of fungal diversity in situ has also benefited from next-generation DNA sequencing technologies. The use of high-throughput sequencing techniques has been widely adopted by the fungal ecology community since the first publication of their use in the field in 2009.[4] Similar to exploration of bacterial diversity, these techniques have allowed high-resolution studies of fundamental questions in fungal ecology such as phylogeography,[5] fungal diversity in forest soils,[6] stratification of fungal communities in soil horizons,[7] and fungal succession on decomposing plant litter.[8] The majority of fungal ecology research leveraging next-generation sequencing approaches involves sequencing of PCR amplicons of conserved regions of DNA (i.e. marker genes) to identify and describe the distribution of taxonomic groups in the fungal community in question, though more recent research has focused on sequencing functional gene amplicons[4] (e.g. Baldrian et al. 2012[7]). The locus of choice ...

Although work on natural populations had been done previously, it is acknowledged that the field was founded by the English biologist E.B. Ford (1901-1988) in the early 20th century. Ford was taught genetics at Oxford University by Julian Huxley, and started research on the genetics of natural populations in 1924. Ford also had a long working relationship with R.A. Fisher. By the time Ford had developed his formal definition of genetic polymorphism,[2] Fisher had got accustomed to high natural selection values in nature. This was one of the main outcomes of research on natural populations. Fords magnum opus was Ecological genetics, which ran to four editions and was widely influential.[3] Other notable ecological geneticists would include Theodosius Dobzhansky who worked on chromosome polymorphism in fruit flies. As a young researcher in Russia, Dobzhansky had been influenced by Sergei Chetverikov, who also deserves to be remembered as a founder of genetics in the field, though his significance ...

Dear Brothers & Sisters in Christ,. May you live and proclaim with love and joy the Gospel of the Family! That was the core message in my Pastoral Letter issued on 29 September 2014, the eve of the Extraordinary Synod which was convoked by Pope Francis to focus on the Pastoral Challenges of the Family in the Context of Evangelization .. I humbly request again your earnest prayers for the Ordinary General Assembly of the Synod of Bishops to be held in coming October to continue the discussions on the theme of the family. Please pray also for the World Meeting of Families to be held on 22-25 September this year in Philadelphia, USA. I have in my said Pastoral Letter tried to identify some key challenges to family life and the mission of the Church. What I wish to do here is to follow up with a few reflections on what Pope Francis, in his Encyclical Letter Laudatio Si (LS), has since said about integral ecology and the need to promote a genuine human ecology of marriage and the family. Let me ...

Ecology became a serious science some 100 years ago when the problems that it sought to understand were clear and simple: the reasons for the distribution and abundance of organisms on Earth. It subdivided fairly early into three parts, population, community, and ecosystem ecology. It was widely understood that to understand population ecology you needed to know a great deal about physiology and behaviour in relation to the environment, and to understand community ecology you had to know a great deal about population dynamics. Ecosystem ecology then moved into community ecology plus all the physical and chemical interactions with the whole environment. But the sciences are not static, and ecology in the past 60 years has come to include nearly everything from chemistry and geography to meteorological sciences, so if you tell someone you are an ecologist now, they have only a vague idea of what you do. The latest invader into the ecology sphere has been conservation biology so that in the last ...
Ecology and evolutionary biology are young sciences, each having coalesced fairly recently from multiple, independent fields of study. For instance, plant physiological ecology, with strong links to agriculture, has an early history quite separate from that of animal physiological ecology, which is rooted in medical research (McIntosh 1985). Progress has occurred and will probably continue to flourish at the boundaries, where parallels between independently studied phenomena can be discovered and pursued. The boundary between the study of facilitation and mutualism may well be one such area.. Mutualisms are reciprocally positive interactions between pairs of species, whether the benefits are quantified in terms of fitness or population dynamics. Although some older discussions restrict the concept to interactions exhibiting specificity and a long evolutionary history, mutualism is now considered to subsume even transient interactions of small effect, so long as both partners experience a net ...

AU - Albert, Cécile H.. AU - Hulshof, Catherine. AU - Jung, Vincent. AU - Messier, Julie. PY - 2012/4/1. Y1 - 2012/4/1. N2 - Despite being recognized as a promoter of diversity and a condition for local coexistence decades ago, the importance of intraspecific variance has been neglected over time in community ecology. Recently, there has been a new emphasis on intraspecific variability. Indeed, recent developments in trait-based community ecology have underlined the need to integrate variation at both the intraspecific as well as interspecific level. We introduce new T-statistics (T for trait), based on the comparison of intraspecific and interspecific variances of functional traits across organizational levels, to operationally incorporate intraspecific variability into community ecology theory. We show that a ...

In the natural world, the waste of one organism is the resource of another organism. This is essentially a cyclical cycle where no waste goes unused. Sadly, current industrial activities are increasingly confrontational with ecological systems. Industrial ecology follows that an ideal industrial system is one which mimics this natural balance, where the wastes of one company is the resources of another. This ideal situation in turn results in the elimination of wastes leaving the industrial ecosystem. Although this may seem nearly impossible, there are many current tools that industries can apply to reach this goal such as cleaner production methods and design for the environment. Industrial ecology also offers important goals, organizing principles and strategies to reform industry. Although many see this as a complete change which may harm industry, industrial ecology first believes that change begins with industry optimization. One reduces energy and raw materials to produce a given good. Any ...

In recent years it has been acknowledged that bacteria engage in a number of diverse social behaviours. An large body of research has focused on the influence that Quorum sensing (QS) has on these behaviours. The majority of this work has traditionally focused on a mechanistic understanding of how QS-dependent genes are regulated, and how this regulation affects cell-cell communication. In contrast, relatively few papers have focused on the functional role that QS provides to bacteria. This has led to confusion, and a number of attempts to unify the process under a functional argument. Correctly understanding the functional role of QS will help inform diverse fields of research ranging from medical to industrial. To help address this, this study focused on three major questions: (i) What is the value to bacteria for releasing and responding to more than one signal molecule? Are bacteria capable of combining the information from more than one signal to resolve the conflation between environmental ...

The Ecological Risk Assessment Specialty Group (ERASG) is currently planning several workshops, including such topics as regional risk assessment, invasive species, climate change, statistical methods, and the integration of human and ecological risk assessment. Anyone with an interest in ecological risk assessment is encouraged to join, from eco-risk practitioners to decision makers relying on these analyses for more effective decision making. We encourage SRA members from all sectors to join the ERASG.. Ecological risk assessment focuses on evaluating the impacts of human activities on ecological systems and the services they provide. As with human health risk assessment, ecological risk assessment has its roots in estimating exposure and risk or hazard from chemicals in the environment, but has expanded in recent years to include the wide range of stressors facing ecological receptors. Risks due to invasive or non-indigenous species, genetically modified organisms, and climate change are ...

Glucosinolates are plant secondary metabolites composed of a thioglucose group and an amino acid side-chain. They occur in the Brassicaceae and related families. A wide variety of glucosinolates exists owing to modification of the side-chain structure. Following tissue damage, myrosinase enzymes catalyse the decomposition of glucosinolates to a variety of volatile and nonvolatile products. The genetic control of concentration and side-chain modification of aliphatic glucosinolates, which have side-chains derived from methionine, are simple and well known from work on Arabidopsis and Brassica crops. In controlled conditions in the laboratory or in field trials, many aliphatic glucosinolates, or their degradation products, affect the behaviour of herbivores. For these reasons, we suggest that polymorphism for aliphatic glucosinolates in natural populations offers an attractive system for the study of ecological genetics of plant-herbivore interactions.

Bookchins theory presents a vision of human evolution that combines the nature of biology and society into a third thinking nature beyond biochemistry and physiology, which he says is of a more complete, conscious, ethical, and rational nature. Humanity, according to this line of thought, is the latest development in the long history of organic development on Earth. Bookchins social ecology proposes ethical principles for replacing a societys propensity for hierarchy and domination with that of democracy and freedom.[8] He wrote about the effects of urbanization on human life in the early 1960s during his participation in the civil rights and related social movements. Bookchin then began to pursue the connection between ecological and social issues, culminating with his best-known book, The Ecology of Freedom, which he had developed over a decade.[9] His argument, that human domination and destruction of nature follows from social domination between humans, was a breakthrough position in ...
Nationally and internationally, soil contamination requiring remediation is a major challenge of concern. It has been estimated by The European Environment Agency that approximately 250,000 sites in the EEA member countries require some kind of action. Ecological Risk Assessment of contaminated land always promotes lively dialogue amongst soil scientists, ecotoxicologists, regulators and local authorities. On the one hand, it seems very obvious and simple, but at the same time difficult to simplify and predict in detail and may, hence, be neglected and circumvented. Via the European Framework R&D project - LIBERATION - the Section of Soil Fauna Ecology and Ecotoxicology published a Decision Support System (DSS) for evaluating ecological risk at contaminated sites. This DSS is not a comprehensive all-you-need-to-have document for managing risk of contaminated land, as it focuses primarily on supporting decisions made when assessing risk to the terrestrial environment. The main objectives of the ...
The next season, we were ready. We had new traps, plus two enatiomers of the candidate pheromone, in order to determine which of the two, or perhaps both were active. We prepared traps with a mixture of the two chemicals (called a racemic mixture or racemate), in order to determine whether one would inhibit the effectiveness of the other. This is important in chemical ecology of insects, as preparation of a racemic mixture is vastly cheaper than production of an enantiomerically pure chemical, and if the racemate is attractive, there is no need to go to the trouble of producing the pure substance.. With the traps out, we waited a week. When we came back, the traps with the racemate and the (R)-desmolactone had caught many many beetles, whereas the control and the traps containing S-desmolactone only had only caught a single beetle each (one trap almost caught a bear, but that is another story). Therefore, the (R)-desmolactone appears to be the sex pheromone of Desmocerus auriepennis, as it was ...

PY - 2006. Y1 - 2006. N2 - The social and economic characteristics of geographic areas are associated with their suicide rates. The extent to which these ecological associations are due to the characteristics of the people living in the areas (compositional effects) or the influence of the areas themselves on risk (contextual effects) is uncertain. Denmarks Medical Register on Vital Statistics and its Integrated Database for Longitudinal Labour Market Research were used to identify suicides and 20 matched controls per case in 25-60-year-old men and women between 1982 and 1997. Individual and area (municipality) measures of income, marital and employment status were obtained. There were 9011 suicides and 180,220 controls. Individual-level associations with these risk factors were little changed when ...

Welcome to the Soil Ecology. The aim of our research is to advance understanding of the diversity and interactions of soil organisms with their environment, and how this affects above- and below-ground ecological processes. In particular, we are interested in the effects of human activity, for example soil management and climate change impacts, on soil organisms and the delivery of ecosystem services important for agricultural and silvicultural production. Such ecosystem services include biological control, soil carbon storage and nutrient cycling. We take a broad approach to research, utilising metagenomics, glasshouse experiments, and field studies..

Microbial ecology is devoted to the understanding of dynamics, activity and interaction of microorganisms in natural and technical ecosystems. Bioelectrochemical systems represent important technical ecosystems, where microbial ecology is of highest importance for their function. However, whereas aspects of, for example, materials and reactor engineering are commonly perceived as highly relevant, the study and engineering of microbial ecology are significantly underrepresented in bioelectrochemical systems. This shortfall may be assigned to a deficit on knowledge and power of these methods as well as the prerequisites for their thorough application. This article discusses not only the importance of microbial ecology for microbial electrochemical technologies but also shows which information can be derived for a knowledge-driven engineering. Instead of providing a comprehensive list of techniques from which it is hard to judge the applicability and value of information for a respective one, this review

We have a new paper in the Early Edition of PNAS on the ecology of plague in prairie dogs. The Stanford News Service did a nice little write-up of the paper (and Mark Shwartzs full version is available on the Woods Institute site) and it has now been picked up by a number of media outlets including USA Today, ScienceDaily, The Register (UK), as well as a couple of radio news shows. This paper has been a real pleasure for me because of my incredible collaborators. Dan Salkeld, who has been a post-doctoral fellow with me and now splits his time between teaching in Human Biology at Stanford and working as an epidemiologist for the California Department of Health, is the lead author. Dan is clearly one of the leading young disease ecologists working today and his understanding of the field and willingness to do the sometimes unglamorous grunt work of ecology in pursuit of important research questions continually impresses me.

Students will conduct a research project as part of the course.. ...
Measurements of body condition are typically used to assess an individuals quality, health, or energetic state. Most indices of body condition are based on linear relationships between body length and mass. Although these indices are simple to obtain, nonlethal, and useful indications of energetic state, their accuracy at predicting constituents of body condition (e.g., fat and lean mass) are often unknown. The objectives of this research were to (1) validate the accuracy of another simple and noninvasive method, quantitative magnetic resonance (QMR), at estimating body composition in a small-bodied lizard, Anolis sagrei, and (2) evaluate the accuracy of two indices of body condition (based on length-mass relationships) at predicting body fat, lean, and water mass ...
Phone: 419-755-4343 My primary interests are in microbial evolutionary ecology and the pharmacodynamics of self-replicating drugs. In both of these areas my concentration is on bacteriophages (phages), the viruses of bacteria. Evolutionary ecology is the study of adaptation, particularly in terms of answering why questions, such as, why do organisms exhibit this behavior rather than another. A periodic emphasis of mine has been on the why of phage infection duration, called latent period. With longer duration phages produce more progeny, per individual infection, whereas with shorter duration they produce those progeny faster, at least on a per bacterial infection basis. More recently I have been studying the ecology and evolutionary ecology of phage interaction with bacteria that are present in a more solid rather than planktonic phase, especially as seen on petri dishes or in biofilms. I use the information gleaned in order to better understand the ecology of phages in general, an important ...
For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes, with the first being physiological ecology, but including an introduction to the broad classification of phyla and classes, morphology, structures, and life cycles. Communities, habitats, roles, and uses, among others, are in various stages of completion. [Information of the supplier, modified ...
Carotenoids are among the most prevalent pigments used in animal signals and are also important for a range of physiological functions. These concomitant roles have made carotenoidbased signals a popular topic in behavioural ecology while also causing confusion and controversy. After a thorough background, we review the many pitfalls, caveats and seemingly contradictory conclusions that can result from not fully appreciating the complex nature of carotenoid function. Current controversies may be resolved through a more careful regard of this complexity, and of the immense taxonomic variability of carotenoid metabolism. Studies investigating the physiological trade-offs between ornamental and physiological uses of carotenoids have yielded inconsistent results. However, in many studies, homeostatic regulation of immune and antioxidant systems may have obscured the effects of carotenoid supplementation. We highlight how carefully designed experiments can overcome such complications. There is also a need to
