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...

*  Diversity–function debate
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...

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.

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...

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 ...

*  Connell–Slatyer model of ecological succession
... Ecological succession can be understood as a process of changing species composition within a community due to an ecological disturbance, and varies largely according to the initial disturbance prompting the succession. The 1977 study The Models Facilitation Model. their relative success in later-successional stages .' Connell & Slatyer, 1121-1124. thumb|200px|Facilitation Model Based on the assumption that only particular species with qualities ideal for “early succession” can colonize the newly exposed landforms after an ecological disturbance. ::*Thus, the presence of early successional species often changes the environment so that the habitat is less hospitable for the original species’ own ecological demands and facilitates the invasion of later-successional species. thumb|200px|Tolerance Model In this case, new pioneer species neither inhibit nor facilitate the growth and success of other species. Eventually, dominant species replace or reduce pioneer species abundance through competition. thumb|20...

... Ecosystem Gas Exchange In order to establish the amount of carbon assimilated by the scrub oak ecosystem exposed to elevated CO 2, we periodically measure net ecosystem gas exchange using the open top chamber fitted with a ventilated top to prevent the backflow of outside air. Hymus et al. Net ecosystem gas exchange NEE was shown to be very close to the measurements obtained by eddy flux methods in scrub oak of the same age Dore et al. Measurements of NEE at elevated CO 2 shows growth in elevated CO 2 increased maximum NEE from 50% in the winter to 180% in the summer Hymus et al., 2003. When expressed per unit leaf area the stimulation of NEE ranged from 7% to 60%, with the increase depending on soil water content: the greater the soil water, the greater was the stimulation of NEE. At night, CO 2 effluxes from the ecosystem were on average 39% higher in elevated CO 2 and varied between 6% and 64%: increased biomass of leaves, high temperature and wetter soil produced greater ecosystem respiration during ...

We studied the relationships between macroinvertebrate species richness and ecosystem functions in a soft-bottom, intertidal system. Low, medium, and high biomass treatments were established by enclosing differing amounts of ambient sediment in defaunated plots. All treatments contained species within the same five main functional groups of macroinvertebrate, but species' identity varied both within and between treatments thus species richness was considered a random, rather than fixed, variable.

Sinks for nitrogen inputs in terrestrial ecosystems: A meta-analysis of 15N tracer field studies. Description: Anthropogenic nitrogen N deposition can have a range of effects on terrestrial ecosystems, but these effects depend in part on the fate of this deposited N, particularly in the amount retained or lost from the system, and in the partitioning of retained N between plants and soils. We conducted a meta-analysis of studies at 48 sites around the world that used enriched 15N isotope tracers to examine the fate of N among ecosystem pools and to compare total ecosystem retention of N across sites. In studies where N was added as a fertili...

Model Output from the Marine Biology Laboratory General Ecosystem Model MBL-GEM for Toolik Lake, 1921-2144, and the Kuparuk River Basin, 1995 Summary This data set contains model input and output data for four simulations of varying time periods and spatial coverage. The first two simulations are for acidic tussock tundra in the Toolik Lake region of the Kuparuk River watershed for the years 1921 to 2144. Each of these simulations is made up of two parts. The first part is based upon a reconstruction of historical climate variables from 1921 to 1995, while the second part is based upon a doubling of C02 and the concurrent changes in temperature, soil moisture, and irradiance from 1996 to 2144.

Island ecosystems are considered the most sensible to anthropogenic influences. Most Brazilian coastal islands have suffered changes on their species composition.Nowadays the Anchieta Island is a protected park, but was hardly deforested and suffered an introduction of mammals, some of which are overpopulated now.Since fauna plays a key role in vegetal community, the loss or change on animal-plant interactions affects the structure and composition of species.We are analyzing the po...

Paul R Epstein, Timothy E Ford, Rita R Colwell. * Waterborne infection, from marine or freshwater sources, is the leading cause of illness worldwide, and fish provide more animal protein for human consumption than poultry or meat. Today the health of large marine ecosystems--their diversity, productivity, and resilience--is threatened. by a "global epidemic" of coastal algal blooms. This overgrowth of algae has profound implications for water and food safety because vibrios adhere to phytoplankton algae and zooplankton, and "red tides" bear biotoxins responsible for fish and shellfish poisoning. Furthermore nutrient-rich effluents stimulate algal growth and warmer sea surface temperatures shift marine ecosystems towards more toxic species. Dormant V cholerae and algal blooms. Cholera becomes endemic when water and sanitation system...

(1/10106) Effect of phenylurea herbicides on soil microbial communities estimated by analysis of 16S rRNA gene fingerprints and community-level physiological profiles.

The effect of three phenyl urea herbicides (diuron, linuron, and chlorotoluron) on soil microbial communities was studied by using soil samples with a 10-year history of treatment. Denaturing gradient gel electrophoresis (DGGE) was used for the analysis of 16S rRNA genes (16S rDNA). The degree of similarity between the 16S rDNA profiles of the communities was quantified by numerically analysing the DGGE band patterns. Similarity dendrograms showed that the microbial community structures of the herbicide-treated and nontreated soils were significantly different. Moreover, the bacterial diversity seemed to decrease in soils treated with urea herbicides, and sequence determination of several DGGE fragments showed that the most affected species in the soils treated with diuron and linuron belonged to an uncultivated bacterial group. As well as the 16S rDNA fingerprints, the substrate utilization patterns of the microbial communities were compared. Principal-component analysis performed on BIOLOG data showed that the functional abilities of the soil microbial communities were altered by the application of the herbicides. In addition, enrichment cultures of the different soils in medium with the urea herbicides as the sole carbon and nitrogen source showed that there was no difference between treated and nontreated soil in the rate of transformation of diuron and chlorotoluron but that there was a strong difference in the case of linuron. In the enrichment cultures with linuron-treated soil, linuron disappeared completely after 1 week whereas no significant transformation was observed in cultures inoculated with nontreated soil even after 4 weeks. In conclusion, this study showed that both the structure and metabolic potential of soil microbial communities were clearly affected by a long-term application of urea herbicides.  (+info)

(2/10106) Polynucleotide probes that target a hypervariable region of 16S rRNA genes to identify bacterial isolates corresponding to bands of community fingerprints.

Temperature gradient gel electrophoresis (TGGE) is well suited for fingerprinting bacterial communities by separating PCR-amplified fragments of 16S rRNA genes (16S ribosomal DNA [rDNA]). A strategy was developed and was generally applicable for linking 16S rDNA from community fingerprints to pure culture isolates from the same habitat. For this, digoxigenin-labeled polynucleotide probes were generated by PCR, using bands excised from TGGE community fingerprints as a template, and applied in hybridizations with dot blotted 16S rDNA amplified from bacterial isolates. Within 16S rDNA, the hypervariable V6 region, corresponding to positions 984 to 1047 (Escherichia coli 16S rDNA sequence), which is a subset of the region used for TGGE (positions 968 to 1401), best met the criteria of high phylogenetic variability, required for sufficient probe specificity, and closely flanking conserved priming sites for amplification. Removal of flanking conserved bases was necessary to enable the differentiation of closely related species. This was achieved by 5' exonuclease digestion, terminated by phosphorothioate bonds which were synthesized into the primers. The remaining complementary strand was removed by single-strand-specific digestion. Standard hybridization with truncated probes allowed differentiation of bacteria which differed by only two bases within the probe target site and 1.2% within the complete 16S rDNA. However, a truncated probe, derived from an excised TGGE band of a rhizosphere community, hybridized with three phylogenetically related isolates with identical V6 sequences. Only one of the isolates comigrated with the excised band in TGGE, which was shown to be due to identical sequences, demonstrating the utility of a combined TGGE and V6 probe approach.  (+info)

(3/10106) Effects of salinity and temperature on long-term survival of the eel pathogen Vibrio vulnificus biotype 2 (serovar E).

Vibrio vulnificus biotype 2 (serovar E) is a primary eel pathogen. In this study, we performed long-term survival experiments to investigate whether the aquatic ecosystem can be a reservoir for this bacterium. We have used microcosms containing water of different salinities (ranging from 0.3 to 3.8%) maintained at three temperatures (12, 25, and 30 degrees C). Temperature and salinity significantly affected long-term survival: (i) the optimal salinity for survival was 1.5%; (ii) lower salinities reduced survival, although they were nonlethal; and (ii) the optimal temperature for survival was dependent on the salinity (25 degrees C for microcosms at 0.3 and 0.5% and 12 degrees C for microcosms at 1.5 to 3.8%). In the absence of salts, culturability dropped to zero in a few days, without evidence of cellular lysis. Under optimal conditions of salinity and temperature, the bacterium was able to survive in the free-living form for at least 3 years. The presence of a capsule on the bacterial cell seemed to confer an advantage, since the long-term survival rate of opaque variants was significantly higher than that of translucent ones. Long-term-starved cells maintained their infectivity for eels (as determined by both intraperitoneal and immersion challenges) and mice. Examination under the microscope showed that (i) the capsule was maintained, (ii) the cell size decreased, (iii) the rod shape changed to coccuslike along the time of starvation, and (iv) membrane vesicles and extracellular material were occasionally produced. In conclusion, V. vulnificus biotype 2 follows a survival strategy similar to that of biotype 1 of this species in response to starvation conditions in water. Moreover, the aquatic ecosystem is one of its reservoirs.  (+info)

(4/10106) Immunochemical detection and isolation of DNA from metabolically active bacteria.

Most techniques used to assay the growth of microbes in natural communities provide no information on the relationship between microbial productivity and community structure. To identify actively growing bacteria, we adapted a technique from immunocytochemistry to detect and selectively isolate DNA from bacteria incorporating bromodeoxyuridine (BrdU), a thymidine analog. In addition, we developed an immunocytochemical protocol to visualize BrdU-labeled microbial cells. Cultured bacteria and natural populations of aquatic bacterioplankton were pulse-labeled with exogenously supplied BrdU. Incorporation of BrdU into microbial DNA was demonstrated in DNA dot blots probed with anti-BrdU monoclonal antibodies and either peroxidase- or Texas red-conjugated secondary antibodies. BrdU-containing DNA was physically separated from unlabeled DNA by using antibody-coated paramagnetic beads, and the identities of bacteria contributing to both purified, BrdU-containing fractions and unfractionated, starting-material DNAs were determined by length heterogeneity PCR (LH-PCR) analysis. BrdU-containing DNA purified from a mixture of DNAs from labeled and unlabeled cultures showed >90-fold enrichment for the labeled bacterial taxon. The LH-PCR profile for BrdU-containing DNA from a labeled, natural microbial community differed from the profile for the community as a whole, demonstrating that BrdU was incorporated by a taxonomic subset of the community. Immunocytochemical detection of cells with BrdU-labeled DNA was accomplished by in situ probing with anti-BrdU monoclonal antibodies and Texas red-labeled secondary antibodies. Using this suite of techniques, microbial cells incorporating BrdU into their newly synthesized DNA can be quantified and the identities of these actively growing cells can be compared to the composition of the microbial community as a whole. Since not all strains tested could incorporate BrdU, these methods may be most useful when used to gain an understanding of the activities of specific species in the context of their microbial community.  (+info)

(5/10106) Morphological and compositional changes in a planktonic bacterial community in response to enhanced protozoan grazing.

We analyzed changes in bacterioplankton morphology and composition during enhanced protozoan grazing by image analysis and fluorescent in situ hybridization with group-specific rRNA-targeted oligonucleotide probes. Enclosure experiments were conducted in a small, fishless freshwater pond which was dominated by the cladoceran Daphnia magna. The removal of metazooplankton enhanced protozoan grazing pressure and triggered a microbial succession from fast-growing small bacteria to larger grazing-resistant morphotypes. These were mainly different types of filamentous bacteria which correlated in biomass with the population development of heterotrophic nanoflagellates (HNF). Small bacterial rods and cocci, which showed increased proportion after removal of Daphnia and doubling times of 6 to 11 h, belonged nearly exclusively to the beta subdivision of the class Proteobacteria and the Cytophaga-Flavobacterium cluster. The majority of this newly produced bacterial biomass was rapidly consumed by HNF. In contrast, the proportion of bacteria belonging to the gamma and alpha subdivisions of the Proteobacteria increased throughout the experiment. The alpha subdivision consisted mainly of rods that were 3 to 6 microm in length, which probably exceeded the size range of bacteria edible by protozoa. Initially, these organisms accounted for less than 1% of total bacteria, but after 72 h they became the predominant group of the bacterial assemblage. Other types of grazing-resistant, filamentous bacteria were also found within the beta subdivision of Proteobacteria and the Cytophaga-Flavobacterium cluster. We conclude that the predation regimen is a major structuring force for the bacterial community composition in this system. Protozoan grazing resulted in shifts of the morphological as well as the taxonomic composition of the bacterial assemblage. Grazing-resistant filamentous bacteria can develop within different phylogenetic groups of bacteria, and formerly underepresented taxa might become a dominant group when protozoan predation is the major selective pressure.  (+info)

(6/10106) Combination of fluorescent in situ hybridization and microautoradiography-a new tool for structure-function analyses in microbial ecology.

A new microscopic method for simultaneously determining in situ the identities, activities, and specific substrate uptake profiles of individual bacterial cells within complex microbial communities was developed by combining fluorescent in situ hybridization (FISH) performed with rRNA-targeted oligonucleotide probes and microautoradiography. This method was evaluated by using defined artificial mixtures of Escherichia coli and Herpetosiphon aurantiacus under aerobic incubation conditions with added [3H]glucose. Subsequently, we were able to demonstrate the potential of this method by visualizing the uptake of organic and inorganic radiolabeled substrates ([14C]acetate, [14C]butyrate, [14C]bicarbonate, and 33Pi) in probe-defined populations from complex activated sludge microbial communities by using aerobic incubation conditions and anaerobic incubation conditions (with and without nitrate). For both defined cell mixtures and activated sludge, the method proved to be useful for simultaneous identification and analysis of the uptake of labeled substrates under the different experimental conditions used. Optimal results were obtained when fluorescently labeled oligonucleotides were applied prior to the microautoradiographic developing procedure. For single-cell resolution of FISH and microautoradiographic signals within activated sludge flocs, cryosectioned sample material was examined with a confocal laser scanning microscope. The combination of in situ rRNA hybridization techniques, cryosectioning, microautoradiography, and confocal laser scanning microscopy provides a unique opportunity for obtaining cultivation-independent insights into the structure and function of bacterial communities.  (+info)

(7/10106) Long-term hantavirus persistence in rodent populations in central Arizona.

For 35 months, we monitored hantavirus activity in rodent populations in central Arizona. The most frequently captured hantavirus antibody-positive rodents were Peromyscus boylii and P. truei. Antibody-positive P. boylii were more frequently male (84%), older, and heavier, and they survived longer on trapping web sites than antibody-negative mice. The number of antibody-positive P. boylii was greater during high population densities than during low densities, while antibody prevalence was greater during low population densities. Virus transmission and incidence rates, also related to population densities, varied by trapping site. The spatial distribution of antibody-positive P. boylii varied by population density and reflected the species preference for dense chaparral habitats. The focal ranges of antibody-positive P. boylii also demonstrated a patchy distribution of hantavirus.  (+info)

(8/10106) Statistical sensitivity for detection of spatial and temporal patterns in rodent population densities.

A long-term monitoring program begun 1 year after the epidemic of hantavirus pulmonary syndrome in the U.S. Southwest tracked rodent density changes through time and among sites and related these changes to hantavirus infection rates in various small-mammal reservoir species and human disease outbreaks. We assessed the statistical sensitivity of the program's field design and tested for potential biases in population estimates due to unintended deaths of rodents. Analyzing data from two sites in New Mexico from 1994 to 1998, we found that for many species of Peromyscus, Reithrodontomys, Neotoma, Dipodomys, and Perognathus, the monitoring program detected species-specific spatial and temporal differences in rodent densities; trap-related deaths did not significantly affect long-term population estimates. The program also detected a short-term increase in rodent densities in the winter of 1997-98, demonstrating its usefulness in identifying conditions conducive to increased risk for human disease.  (+info)

I ever posted similar q in other hosts, but I was told that Vegetarian Revolution is very much commensurate to ecosystem & biodiversity. Being a VorV should anyone know this matter better? Show also resources and link, hence others will stem from it.

Help me please. Max 10 points for the best research.
(For the trolls as usual, could infringe for the sake of 2 points)

Biodiversity includes those species who live differently than you. That means those who choose to eat meat as animals (including the human species of animal) eat a variety of foods that are available to them.

Good you mentioned ecosystem as  I am interested in your views about an eco system where plant foods are scarce. a good example would be a desert ecosystem or a tundra ecosystem. Or even a rainforest ecosystem wher open arable land in which to plant is not readily available but hunting is very much viable.


Is toothpaste bad for the ecosystem?


I wonder this cause we're always spitting it down the drain... what kind of effects does this have on the oceans/environment?
on the same note: what about mouth wash? or the soap from washing dishes or laundry?  what kind of effects do these have on the environment?
----------

Not as bad for it as is the mouth that doesn't use toothpaste.


how do you demonstraite an ecosystem?

We had to do this in school this year!

What we did was we made food webs and food chains to show the ways in which everything interacts. For example:

Small Fish -----------> Penguins --------------> Seals -----------> Whales

This is showing which animals rely on who to survive in an ecosystem. 

A food web is basically the same, but it goes in all different directions, not just one. To represent an ecosystem, you should draw a food web on a background showing the environment in which the ecosystem is, e.g. you could draw a food web about animals in the South Pole on a snow scene background.

Or something like that.

Good Luck, hope this helps!!! :o)


i have a natural ecosystem in my backyard i need to preserve, HELP!!?


how can i save it from its destruction by  a national multi billion dollar building company
----------

If you don't own the land now, maybe try to make it a park.  Work with the building company to mitigate any damage to the ecosystem.  Get your local newspaper or tv station involved.  Shame can go a long way to encouraging corporations to do the right thing.


What are your thoughts about the Asian delicacy shark fin soup?


I just wanted to see what are your thoughts.  I am not against anyone's way of living.  But to see your opinion.  

I think it would be nice if more people were to get educated about sharks and their behavior.  The reason I love these amazing creatures is because they have been around for 400 million years.  And we humans greatly diminish its populations in several decades.  And if they go extinct, then that would upset the ecosystem and other marine species suffer as well.  The ecosystem accounts for much of the oxygen's supply on Earth.

While a chef and working in Asia (Singapore and Japan) I saw many types of fins from a variety of sharks, now that was in the 1980's, if they used the whole shark for food it would be better, but to just cut off the fins and then chuck it back into the ocean to die a horrible death is just plain wrong, I have when I was in Asia had it in soups, braised dishes with abalone and in 1000 treasure sandypot dishes. If eaten alone it is like spaghetti squash, chewy, translucent and not much flavour, it is how it is cooked and what it cooked with.

As the one Chinese person said it is a festive dish served at special occasions, for wedding I am told it show the family is well off, but there is a health property to it to, it is to promote the bride's fertility.


What kind if skin product should I use to make my pores smaller and face less blotchy?


I have no serious acne issues as I may get a pimple here and there. My skin isn't overly dry or oily. I use oil of olay soap and a daily skin cream and my skin's ecosystem seems to stay in balanace and I defintely do not want to mess with the chemistry on my face but I would like to find a daily cleanser that would make my pores less visible and my skin look evenly toned. Any suggestions?
----------

Well it sounds like your face is nice and smooth and healthy. Why get something you don't need? I wouldn't risk it! My mom has a very clean face and when she bought some cream she broke out in a rash and her face got dry. She had to return the cream. They say it might have been because you are over doing what you do on your face. But you can try putting powder all over your face so nothing will show on your face! Well really I don't think you need any cream because if you do get some you can have a risk of breaking out in rashes and getting a dry face because you sound like you really don't need it!
