... "Ecological Genetics". B Ford Ecological Genetics book. 'Ecological genetics' is the study of genetics in natural populations. Research in this field is on traits of ecological significance—that is, traits related to fitness, which affect an organism's survival and reproduction. Research usually involves a mixture of field and laboratory studies. Ford E.B. Changes in the populations at different times and places will be noted, and the pattern of mortality in these populations will be studied. History See also References Further reading. Ford was taught genetics at Oxford University by Julian Huxley, and started research on the genetics of natural populations in 1924. Oxford University Press. Ford E.B. All Souls Studies, Faber & Faber, London. Ford E.B. 'Ecological genetics', 4th ed.

*  Spatial ecology
... can be distinguished by two different approaches: the field of landscape ecology and, the field of metapopulation ecology. In spatial ecology, scale refers to the spatial extent of ecological processes and the spatial interpretation of the data. Spatial autocorrelation and the scaling of species–environment relationships. 'Ecology' 91: 2455–2465. Most often, ecological patterns are a result of multiple ecological processes, which often operate at more than one spatial scale. Induced spatial autocorrelation or 'induced spatial dependence ' arises from the species response to the spatial structure of exogenous external factors, which are themselves spatially autocorrelated. Spatial patterns, such as the distribution of a species, are the result of either true or induced spatial autocorrelation. In nature, organisms are distributed neither uniformly nor at random. The analysis of spatial ecological patterns comprises two families of methods;. Analysis of spatial trends has been used to research wildlife man...

A major challenge in science writing is how to effectively communicate real, scientific uncertainty. Â Sometimes we just don’t know have enough information to make accurate predictions. Â This is particularly problematic in the case of rare events in which the potential range of outcomes is highly variable. Two topics that are close to my heart come to mind immediately as examples of this problem: 1 understanding the consequences of global warming and 2 predicting the outcome of the emerging A H1N1 “swine flu” influenza-A virus. Harvard economist Martin Weitzman has written about the economics of catastrophic climate change something I have discussed before.

As a result, the production of wheat and rice has increased manifold. Consequently, ground water has become a major source of irrigation in the state. A look at the temporal dimension of categorization of blocks shows that in year 1984, 44.92% blocks were the ‘over-exploited’ and about 49% blocks were classified as semi-critical or safe. But by the year 1992, 52% of the blocks fell into the category of ‘over-exploitation’ and the share of semi-critical and safe blocks went down to 40%. Currently, as per the 2004 statistics, the number of ‘over-exploited’ blocks has risen to 75.18% and the number of ‘semi-critical’ and ‘safe’ blocks has shrunk to 21%. In addition, the state has moved from growing a previously healthy mix of crops such as wheat, maize, pulses and vegetables to now devoting nearly 80% of its crop area to rice and wheat, two of the most water-intensive crops. Overall, the central and state level agriculture policy – consisting of minimum support prices, effective procurement of selected crops, in...

The concept of ecosystem services has been developed to aid our understanding of the human use and management of natural resources. Our health and wellbeing depends upon the services provided by ecosystems and their components: water, soil, nutrients and organisms. Therefore, ecosystem services are the processes by which the environment produces resources utlilised by humans such as clean air, water, food and materials. Ecosystem services can be defined in various ways. The Millennium Ecosystem Assessment provided the most comprehensive assessment of the state of the global environment to date; it classified ecosystem services as follows: Supporting services: The services that are necessary for the production of all other ecosystem services including soil formation, photosynthesis, primary production, nutrient cycling and water cycling.

A global synthesis reveals biodiversity loss as a major driver of ecosystem change. Further species loss will accelerate change in ecosystem processes, but it is unclear how these effects compare to the direct effects of other forms of environmental change that are both driving diversity loss and altering ecosystem function. Here we use a suite of meta-analyses of published data to show that the effects of species loss on productivity and decomposition--two processes important in all ecosystems--are of comparable magnitude to the effects of many other global environmental changes. In experiments, intermediate levels of species loss 21-40% reduced plant production by 5-10%, comparable to previously documented effects of ultraviolet radiation and climate warming. At intermediate levels, species loss generally had equal or greater effects on decomposition than did elevated CO 2 and nitrogen addi...

Functional diversity, composition, and species richness affect the biogeochemical processes of ecosystem s. However, the degree to which these factors influence ecosystems and whether that influence is significant is much debated. In the article 'The Influence of Functional Diversity and Composition on Ecosystem Processes,' Tilman, D., Knops, J, Wedin, D., Reich, P., Ritchie, M., and E. 'The Influence of Functional Diversity and Composition on Ecosystem Processes'. scientists reported on an experiment in which they studied the effects of plant species diversity, functional diversity, and functional composition on ecosystem processes, as measured in six response variables productivity, plant % N, plant tot. The statistical results show that functional diversity and species composition significantly affected the six response variables to a greater extent than species diversity. By themselves, all three factors significantly affected ecosystem processes and also influenced each other. Uncertainty is implied in t...

In natural ecosystems, the effects of abiotic and land use drivers on ecosystem services are usually more important than changes in species richness. The type of poverty experienced by individuals will therefore differ for different rates and levels of biodiversity and ecosystem services loss and if the loss is transitory or permanent. The direct drivers of biodiversity loss in southern Africa include the impacts of land use change, alien invasives, overgrazing, and over- harvesting all of which have already had a large impact on the region s biodiversity, ecosystem services, and human well-being, and all of which are likely to spread in the absence of interventions. Observed recent changes in climate, especially warmer regional temperatures, have already had signifi cant impacts on biodiversity and ecosystems, including causing changes in species distributions, population sizes, the timing of reproduction or migration events, and an increase in the fre quency of pest and disease outbreaks.

... Astronomy Space. January 10, 2011 Water most likely basis for complex ecosystem development January 10, 2011 By Steve Nerlich, Universe Today. But given the chemical possibilities available from the most abundant elements in the universe, even an alien scientist with a different biochemistry would probably agree that a water-solvent-based biochemistry is quite likely to occur elsewhere in the universe and might well be the most likely foundation for a complex ecosystem in which intelligent life could develop. Based on what we know of life and biochemistry, it seems likely that an alien biochemistry will need a solvent like water and one or more elemental units for its structure and function like carbon. Nonetheless, from the list of potentially abundant solvents in the universe, water looks to be the best candidate to support a complex ecosystem. Water also has the advantages of: having strong hydrogen bonds that gives it a strong surface tension three times that of liquid ammonia which would encourage t...

Climate change and human health Global environmental change Policy Training Projects Media centre Partnerships Resources Publications Links. Ecosystem goods and services for health. Why do ecosystems matter for human health. Ecosystem services are the benefits that people obtain from ecosystems. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment. Human health ultimately depends upon ecosystem products and services such as availability of fresh water, food and fuel sources which are requisite for good human health and productive livelihoods. The types of health effects experienced are determined by the degree to which local population’s depend on ecosystem services, and factors such as poverty which affect vulnerability to changes in elements like access to food and water.

*  Ecological Succession
"Ecological succession" is the observed process of change in the species structure of an ecological community over time. This observed change over time in what is living in a particular ecosystem is "ecological succession". As long as the ecosystem's set of environmental conditions remains constant, those species optimally adapted to those conditions will flourish. The "engine" of succession, the cause of ecosystem change, is the impact of established species have upon their own environments. The rise and the decline of numerous species within our various communities illustrates both of the types of motive forces of succession: the impact of an established species to change a site's environmental conditions, and the impact of large external forces to suddenly alter the environmental nature of a site. The consequence of this hardwood tree growth is the increased shading and subsequent mortality of the sun loving red pines by the shade tolerant hardwood seedlings. The shaded forest floor conditions generated by...

... Writing Assignment on Ecosystems Complete the following questions and s ubmit answers for grade. We hear the word ecosystem used frequently in the news today. In your own words, explain what an ecosystem is. Be specific. 2 Describe in as much detail as you can what factors determine the type of ecosystem biome found in a given geographic area. 3 Select an ecosystem pond, salt marsh, deciduous forest, old field, etc. and explain a food web that occurs in that ecosystem. Label plants and animals as specifically as possible and indicate the trophic level they occupy. 4 It is intuitively obvious that there are few large predators in an ecosystem; there is even a book about why large, fierce animals are rare. The grizzly bear requires any where from 11 square miles to 1000 square miles of habitat for its home range. The average in the Brooks Range of Alaska where there is minimal human interference is 521 square miles. Range size seems to be at least a factor of richness of food supplies. From your knowledge ...

Overview {{anchor|GPP and NPP}}Gross primary production and net primary production Terrestrial production Oceanic production Light. Primary Production and Plant Biomass for the Earth From R.H. Gross primary production and net primary production. Terrestrial Higher Plant Respiration and Net Primary Production. Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy GPP and the rate at which they use some of that energy during respiration. Net photosynthesis in the water column is determined by the interaction between the photic zone and the mixed layer. When it is much deeper than the photic zone, this results in phytoplankton spending too much time in the dark for net growth to occur. However, as long as the photic zone is deep enough, primary production may continue below the mixed layer where light-limited growth rates mean that nutrients ar...

... These include primary productivity production of biomass, decomposition, and trophic interactions. in: 'Ecology' 84:2867-2876. Biogeochemistry and hydrology focus on several fundamental ecosystem processes such as biologically mediated chemical cycling of nutrients and physical-biological cycling of water. Trophic dynamics. Net primary productivity NPP is the primary measure of biomass accumulation within an ecosystem. Decomposition and nutrient cycling are fundamental to ecosystem biomass production. Decomposition of plant litter accounts for the majority of nutrients recycled through ecosystems Figure 3. Rates of plant litter decomposition are highly dependent on litter quality; high concentration of phenolic compounds, especially lignin, in plant litter has a retarding effect on litter decomposition. "Nitrogen and lignin control of hardwood leaf litter decomposition dynamics". Globally, rates of decomposition are mediated by litter quality and climate.

Accounting for Nature's Benefits: The Dollar Value of Ecosystem Services Healthy ecosystems provide us with fertile soil, clean water, timber, and food. In 1997 Robert Costanza, Distinguished University Professor of sustainability at Portland State University, Oregon, and colleagues first estimated that ecosystem services worldwide are worth an average $33 trillion annually $44 trillion in today s dollars, nearly twice the global GNP of around $18 trillion $24 trillion in today s dollars. But he adds that some benefits probably came at the expense of natural capital elsewhere in the world, as declines in forest cutting coincided with a rise in imported timber. Another leader in guiding decision makers on payments for ecosystem services is the Natural Capital NatCap Project, cofounded by Stanford s Daily in ...

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

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)

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

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)

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

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)

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

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)

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

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)

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

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)

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

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)

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

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)

Estimates vary from a "low" of 5% to a "high" of 15% of the total world population follows a vegetarian diet, However there are several unknown factors. People who follow a certain religion may be classified as vegetarian. However, whether they actually follow their religion's "rules" on eating cannot be fully determined. People who cannot afford meat/meat products  can be classified as "vegetarian" but they would otherwise eat meat if and when available. Again, the numbers cannot be determined with certainty.

The fourth poster is wrong I think. The figure 3.2% applies only to the United States. 7.9 million is not 3.2% of a world population of almost 6 billion in any case

ELLIOTT NESS
The Garden of Eden, God's perfect world, was vegetarian (Gen. 1:29-30). Immediately, God calls this ideal and non-exploitative relationship "good" (Gen. 1:31). There follow many years of fallen humanity, when people held slaves, waged war, ate animals and committed various other violent acts. But the prophets tell us that the peaceable kingdom will be nonviolent and vegetarian; even the lion will lie down with the lamb (e.g., Isaiah 11). Jesus is the Prince of Peace, who ushers in this new age of nonviolence. When Christians pray, "Your will be done, on Earth as it is in heaven," the one prayer given to us by Jesus, this obligates us to change our lives, to make choices that are as merciful and loving as possible. There will be no factory farms and slaughterhouses in heaven.

God created every animal with the capacity for pain and suffering. But on today's factory farms, animals are dehorned, debeaked, and castrated without anesthesia. To maximize profits, they are crowded together in the least space possible, and are genetically bred, so that most suffer lameness, crippling leg deformities, or bone breaks, because their legs can't keep up with their scientifically enhanced bodies. Finally, they are trucked without food or water, through all weather extremes, to a frightening and hellish death.



To answer...
1. Don't fund animal torture.
2. Want to be healthy.
3. Don't want to eat blood pus, sh*t, and steroids.

Definitely boycotting horrifically cruel industries. And telling anyone and everyone about it.


Where do Goya Beans get their beans?


I'm doing a project for my ecology class on Beans and Lentils and was hoping to track down where the beans in my kitchen originally came from, or at least a general area. Does anyone know where Goya buys their beans?

My first thoughts went to Malta Goya , Goya Malt Beverage.

What should I do with my life?


I am almost done my Physics undergraduate degree, but I don't know what I want to do with it. The only reason I am in physics is because I find the material interesting, but I think nature/ecology is my true calling. It's too late for me to switch majors and my marks probably aren't good enough to get into grad school. What should I do?
----------

First, I want to say congrats on a degree in physics. I had to take a college physics class this summer and it was the hardest class i ever took, so i know that was hard work!

I have a BA in liberal studies which means I pretty much had no choice but to go to grad school, you on the other hand, have a degree that not too many people have (because it's hard!) so there should be tons of good paying jobs even at the Bachelor level with a physics degree (a job i could never get!) It sounds like you just need to set up an appointment with an advisor. They know all the jobs you can apply for and can help you out if you want to go to grad school and possibly go a slightly different direction. Many times you'll only  need a few pre-req classes to be accepted. Find out what your degree is good for because I know that took effort.

P.s. don't say you can't get into grad school because of your marks. Admissions KNOW that you're going to have WAYYY lower marks than say a liberal studies student because your major was a zillion times harder, so a ton of people still get in. talk to an advisor!
