%X Arctic tundra has large amounts of stored carbon and is thought to be a sink for atmospheric carbon dioxide (CO2) (0.1 to 0.3 petagram of carbon per year) (1 petagram = 10 15 grams). But this estimate of carbon balance is only for terrestrial ecosystems. Measurements of the partial pressure of CO2 in 29 aquatic ecosystems across arctic Alaska showed that in most cases (27 of 29) CO2 was released to the atmosphere. This CO2 probably originates in terrestrial environments; erosion of particulate carbon plus ground-water transport of dissolved carbon from tundra contribute to the CO2 flux from surface waters to the atmosphere. If this mechanism is typical of that of other tundra areas, then current estimates of the arctic terrestrial sink for atmospheric CO2 may be 20 percent too high.

%X Growth, flowering, and nutrient content of Eriophorum vaginatum were observed annually over 4 yr at 34 sites spanning 5.5° latitude and 1050 m elevation in northern and central Alaska. We found a strong correlation between the average number of thawing degree—days during the growing season and the peak—season leaf mass per tiller. However, the results from reciprocal transplant gardens established at five sites suggested the correlation was due more to genetic differences among populations than to direct climatic effects. Other variables showed little correlation with long—term degree—day averages, and leaf N and P concentrations were site specific. A year of high inflorescence density at any site along the latitudinal transect was likely to be a high flowering year at all other sites. However, a year of above—average growth north of the Brooks Range did not always coincide with above—average growth to the south, and vice versa. The greatest year—to—year variation was in inflorescence density; least variation was in leaf mass per tiller an N and P concentrations. We conclude that yearly variation in weather affects plants on a broad regional scale, but specific controls over flowering versus growth differ in their geographic extent.

%X Lakes and streams in the foothills near Toolik Lake, Alaska, at 68 degree N have been studied since 1975 to predict physical, chemical and biological impacts of future global change. Experimental manipulations include whole lake and continuous stream fertilization as well as removal and addition of predators (copepods, lake trout, grayling, sculpin). Based on our evidence the following scenario is likely. Warming thaws the upper layers of permafrost and streams and lakes become enriched with phosphorus. Streams respond quickly with higher production of diatoms but animal grazers keep biomass changes to a minimum. Fish productivity also increases. If phosphorus levels are too high, mosses become the dominant primary producer and sequester all of the nutrients. Growth of Arctic grayling under the present conditions only occurs in summers with higher than average stream flow. The present population would be stressed by warmer temperatures. When higher phosphorus levels reach lakes and cause slight eutrophication, the number of trophic levels will increase, especially within the microbial food web. Warmer lake temperatures increase stratification and, combined with entrophication, could decrease oxygen in the hypolimnion. Oxygen levels will also decrease in winter under the ice cover. Eventually this habitat change will eliminate the lake trout, a top predator. Removal of lake trout results in a striking increase in abundance and productivity of smaller fish, including small lake trout, and the emergence of burbot as an alternate top predator. Large species of zooplankton will become virtually extinct.

%X Assessments of carbon (C) fluxes in the Arctic require detailed data on both how and why these fluxes vary across the landscape. Such assessments are complicated because tundra vegetation has diverse structure and function at both local and regional scales. To investigate this diversity, the Arctic Flux Study has used the eddy covariance technique to generate ecosystem CO2-exchange data along a transect in northern Alaska. We use an extant process-based model of the soil–plant–atmosphere continuum to make independent predictions of gross photosynthesis and foliar respiration at 9 of the sites along the transect, using data on local canopy structure and meteorology. We make two key assumptions: (i) soil respiration is constant throughout the flux measurement period, so that the diurnal cycle in CO2 exchange is driven by canopy processes only (except at two sites where a soil respiration–temperature relationship was indicated in the data); and (ii) mosses and lichens play an insignificant role in ecosystem C exchange, even though in some locations their live biomass exceeds 300 g m-2. We found that even with these assumptions the model could explain much of the dynamics of net ecosystem production (NEP) at sites with widely differing vegetation structure and moss/lichen cover. Errors were mostly associated with the predictions of maximum NEP; the likely cause of such discrepancies was (i) a mismatch between vegetation sampled for characterizing the canopy structure and that contained within the footprint of the eddy covariance flux measurements, or (ii) an increase in daytime soil and root respiration. Thus the model results tended to falsify our first assumption but not our second. We also note evidence for an actual reduction in NEP caused by water stress on warm, dry days at some sites. The model–flux comparison also suggests that photosynthesis may be less sensitive to low temperatures than leaf-level gas-exchange measurements have indicated.

%X Recent overviews have suggested that the relationship between species richness and productivity (rate of conversion of resources to biomass per unit area per unit time) is unimodal (hump-shaped). Most agree that productivity affects species richness at large scales, but unanimity is less regarding underlying mechanisms. Recent studies have examined the possibility that variation in species richness within communities may influence productivity, leading to an exploration of the relative effect of alterations in species number per se as contrasted to the addition of productive species. Reviews of the literature concerning deserts, boreal forests, tropical forests, lakes, and wetlands lead to the conclusion that extant data are insufficient to conclusively resolve the relationship between diversity and productivity, or that patterns are variable with mechanisms equally varied and complex. A more comprehensive survey of the ecological literature uncovered approximately 200 relationships, of which 30% were unimodal, 26% were positive linear, 12% were negative linear, and 32% were not significant. Categorization of studies with respect to geographic extent, ecological extent, taxonomic hierarchy, or energetic basis of productivity similarly yielded a heterogeneous distribution of relationships. Theoretical and empirical approaches increasingly suggest scale-dependence in the relationship between species richness and productivity; consequently, synthetic understanding may be contingent on explicit considerations of scale in analytical studies of productivity and diversity.

%X Naeem formalized the relationships among species diversity, functional groups, species redundancy, and ecosystem reliability. Although we applaud his efforts and agree with many of his conclusions, we disagree with some fundamental assumptions used in the derivation of Naeem's equation 2. These assumptions affect some of the conclusions concerning the role of redundancy. We discuss two possible interpretations of Naeem's equation. Under the first interpretation, the equation relates to the probability that a species is present at a particular time t. Under the second interpretation, the equation relates to the probability that a species is present at least once during the interval of time between time 0 and time t. Under this second interpretation we also disagree with the application of Naeem's equation 4.

%X We are developing a process-based modelling approach to investigate how carbon (C) storage of tundra across the entire Arctic will respond to projected climate change. To implement the approach, the processes that are least understood, and thus have the most uncertainty, need to be identified and studied. In this paper, we identified a key uncertainty by comparing the responses of C storage in tussock tundra at one site between the simulations of two models – one a global-scale ecosystem model (Terrestrial Ecosystem Model, TEM) and one a plot-scale ecosystem model (General Ecosystem Model, GEM). The simulations spanned the historical period (1921–94) and the projected period (1995–2100). In the historical period, the model simulations of net primary production (NPP) differed in their sensitivity to variability in climate. However, the long-term changes in C storage were similar in both simulations, because the dynamics of heterotrophic respiration (RH) were similar in both models. In contrast, the responses of C storage in the two model simulations diverged during the projected period. In the GEM simulation for this period, increases in RH tracked increases in NPP, whereas in the TEM simulation increases in RH lagged increases in NPP. We were able to make the long-term C dynamics of the two simulations agree by parameterizing TEM to the fast soil C pools of GEM. We concluded that the differences between the long-term C dynamics of the two simulations lay in modelling the role of the recalcitrant soil C. These differences, which reflect an incomplete understanding of soil processes, lead to quite different projections of the response of pan-Arctic C storage to global change. For example, the reference parameterization of TEM resulted in an estimate of cumulative C storage of 2032 g C m-2 for moist tundra north of 50°N, which was substantially higher than the 463 g C m-2 estimated for a parameterization of fast soil C dynamics. This uncertainty in the depiction of the role of recalcitrant soil C in long-term ecosystem C dynamics resulted from our incomplete understanding of controls over C and N transformations in Arctic soils. Mechanistic studies of these issues are needed to improve our ability to model the response of Arctic ecosystems to global change.

%X 1 Arctic terrestrial ecosystems, which are important components of the global carbon (C) cycle, are expected to undergo considerable future climate change. However, predicting arctic C budgets is complex because the landscape is highly diverse and plant biomass very variable. 2 We investigated the diversity of vegetation at 14 sites along an arctic transect in northern Alaska, including sites on wet coastal tundra, tussock tundra, heath and shrub tundra. We applied these data to a model of the soil-plant-atmosphere (SPA) continuum, to investigate how variations in vegetation structure might affect landscape patterns of gross primary productivity (GPP). 3 Although the dominant species varied, there was a highly significant relationship for vascular plants between the leaf area index (LAI) and total foliar nitrogen (N; g m super(-2) ground area) at each site. 4 A modelled response surface of GPP to changes in both N and LAI indicated that for tundra plants there is an almost constant ratio between the sensitivity of productivity to the two variables. 5 The conservative nature of canopy LAI-N ratios simplifies the task of generating regional predictions of C assimilation by vascular plants (for which LAI and N are key requirements) because measurements of LAI can be used to infer N. 6 Spatial and temporal patterns of LAI and N must be determined if the photosynthetic component of regional C budgets is to be modelled accurately for diverse arctic ecosystems. Patterns of solar irradiance, together with air temperature and soil moisture constraints, are also influential but less important. The contribution of bryophytes must be accounted for as well.

%X Plant species collected from tundra ecosystems located along a north-south transect from central Alaska to the north coast of Alaska showed large and consistent differences in super(15)N natural abundances. Foliar delta super(15)N values varied by about 10ppt among species within each of two moist tussock tundra sites. Differences in super(15)N contents among species or plant groups were consistent across moist tussock tundra at several other sites and across five other tundra types at a single site. Ericaceous species had the lowest delta super(15)N values, ranging between about -8 to -6ppt. Foliar super(15)N contents increased progressively in birch, willows and sedges to maximum delta super(15)N values of about +2ppt in sedges. Soil super(15)N contents in tundra ecosystems at our two most intensively studied sites increased with depth and delta super(15)N values were usually higher for soils than for plants. Isotopic fractionations during soil N transformations and possibly during plant N uptake could lead to observed differences in super(15)N contents among plant species and between plants and soils. Patterns of variation in super(15)N content among species indicate that tundra plants acquire nitrogen in extremely nutrient-poor environments by competitive partitioning of the overall N pool. Differences in plant N sources, rooting depth, mycorrhizal associations, forms of N taken up, and other factors controlling plant N uptake are possible causes of variations in delta super(15)N values of tundra plant species.

%X  Species diversity in the Arctic varies dramatically across abiotic gradients, including topography, moisture, pH and nutrient availability. We hypothesized that vascular plant species density, richness and diversity in Alaskan tundra would be correlated with: (i) site age, (ii) soil pH, (iii) above-ground productivity and biomass, and (iv) spatial heterogeneity. We sampled moist tussock, snowbed and watertrack communities in three sites that differed in substrate age (11 000-4.5 million years since deglaciation) for a variety of environmental and vegetation data over one growing season. 2 Productivity, biomass and heterogeneity were not consistently correlated with species density. However, variation in canopy height was correlated with species density and richness in a unimodal fashion, suggesting that heterogeneity of the light regime may be important for maintaining higher species numbers. 3 The 11 000-year-old site supported more vascular plant species than the two older sites, primarily due to greater numbers of forb species on the youngest site. 4 Soil pH was significantly positively correlated with species richness (R super(2) = 0.82) and species density (R super(2) = 0.61). In general the species found on acidic substrates (pH < 5.5) also occurred on non-acidic substrates (pH > 5.5). 5 This pattern of higher richness with higher pH occurs across other tundra types throughout the Arctic, suggesting that soil pH is an important filter of the regional species pool within northern regions, although other factors may become more important at local scales.

%K Carbon cycle; Human impact; Biosphere; Terrestrial ecosystems;
%X Understanding terrestrial carbon metabolism is critical because terrestrial ecosystems play a major role in the global carbon cycle. Furthermore, humans have severely disrupted the carbon cycle in ways that will alter the climate system and directly affect terrestrial metabolism. Changes in terrestrial metabolism may well be as important an indicator of global change as the changing temperature signal. Improving our understanding of the carbon cycle at various spatial and temporal scales will require the integration of multiple, complementary and independent methods that are used by different research communities. Tools such as air sampling networks, inverse numerical methods, and satellite data (top-down approaches) allow us to study the strength and location of the global- and continentalscale carbon sources and sinks. Bottom-up studies provide estimates of carbon fluxes at finer spatial scales and examine the mechanisms that control fluxes at the ecosystem, landscape, and regional scales. Bottom-up approaches include comparative and process studies (for example, ecosystem manipulative experiments) that provide the necessary mechanistic information to develop and validate terrestrial biospheric models. An iteration and reiteration of top-down and bottom-up approaches will be necessary to help constrain measurements at various scales. We propose a major international effort to coordinate and lead research programs of global scope of the carbon cycle.

%X The aims of this article are to characterize the nutrient regime in arctic and boreal wetlands and to review published data on various aspects of within-stand nutrient-cycling. Most northern wetlands, such as boreal and arctic ombrogenous bogs and most arctic mesic and wet ecosystem types, are poor in inorganic, plant-available nutrients because mineralization is restricted due to low temperatures and anoxic soils. This is particularly true in the Arctic because nutrient inputs from external sources quite often are small, and nutrient pools in the vegetation also are small. By contrast, the soil and the microbial biomass often contain large stocks of organically fixed nutrients that are largely unavailable to plants. The vegetation is adapted to the low availability of nutrients by the perennial nature of both entire plants and plant tissues, which minimizes the annual nutrient losses and reduces the demand for nutrient uptake to produce new tissues. Furthermore, many of the dominant plant life-forms can use soil organic nitrogen (N), either by direct uptake or through connections with ericoid or ectotrophic mycorrhizae, which reduces competition from other plant groups without the ability to utilize organic N. As soil fertility increases, productivity also increases. However, at least in geogenous ("mineral fed") Arctic wetlands, vascular-plant turnover time is surprisingly constant across nutrient and moisture gradients. This is mainly because communities with a species stock having high leaf turnover rates generally have slow stem and belowground turnover rates and vice versa. Turnover times of the bulk soil organic matter, by contrast, range from a few decades in the most productive systems to several centuries in the most nutrient-deficient and wettest ecosystem types. This is because decomposition rates of the soils are controlled by varying environmental conditions, and nutrients can be strongly immobilized within the soil-microbial ecosystem compartment if the soil is nutrient poor. The composition of the vegetation regulates the turnover of plants and plant nutrients but plays a minor role for the function of the entire plant-soil system. Hence, characteristics of nutrient cycling at the stand level are relatively unimportant for the function of the overall soil-plant systems, and characteristics of the plants (nutrient resorption, tissue type, longevity, etc.) mirror the functioning of the system rather than play a major role in regulating ecosystem function. However, several uncertainties about the detailed function of the ecosystems are still unresolved and are highlighted in this compilation.

%X Tundra ecosystems appear to recover slowly from disturbance, but little long-term data concerning plant diversity has been available. We examined recovery of tundra vegetation in Alaska, U.S.A., 23 yr after fire and 24 yr after bulldozing. Primary productivity, depth of thaw, and vascular plant diversity were compared between disturbed and undisturbed tundra to determine whether recovery was complete. Productivity, species richness, and diversity did not differ between burned and unburned plots. Depth of thaw, however, remained greater in burned relative to unburned plots. In contrast, depth of thaw was the only characteristic that did not differ between bulldozed and control plots. Productivity and species richness were greater in bulldozed plots, but diversity was less than control plots. The differences between the two disturbances suggest that, ultimately, recovery depends more on the impact of disturbance on vegetation than changes in the abiotic environment. Vegetative propagules persisted in the soil after fire, but not bulldozing. Therefore, recolonization after fire included plants from the seed bank and vegetative propagules. Vegetation on bladed plots was dominated only by seed bank species. Thus, more than two decades after disturbance, recovery of tundra vegetation appeared to be a function of the nature of the disturbance.

%X The seasonal patterns of leaf exsertion, elongation, and senescence were described and compared for two of the most abundant graminoid species of Alaskan moist tussock tundra, Eriophorum vaginatum and Carex bigelowii. In addition the responses of both species to NPK fertilizer and to variation in site fertility (water track vs. non-track areas) were also assayed and compared. The research was done over two full growing seasons at two sites near Toolik Lake, Alaska, where other aspects of the ecology of both species have been the subject of intensive and ongoing research. Both species showed the typical graminoid pattern of sequential leaf growth, in which the exsertion and elongation of new leaves is coincident with the senescence of old leaves. However, the rates of these processes were much slower and steadier in Eriophorum than in Carex, with much greater overlap in the life histories of individual leaf cohorts. The total and green leaf lengths of whole tillers in Eriophorum were also less variable over the entire year than in Carex. The conclusion is that leaf growth in Carex should depend more on external storage of carbon and nutrients than Eriophorum, with a much greater seasonal variation in demands on storage and retranslocation to and from leaves. The effects of fertilizer and the water track on leaf growth dynamics and turnover rates were largely nonsignificant, despite major effects on total tiller size and productivity. This is in contrast to previous research on evergreen leaf dynamics, but similar to results of previous research on overall production and biomass regulation in Eriophorum. It is concluded that the graminoid response to increased nutrient availability in the Arctic is to dilute the greater amounts of nutrient uptake by greater growth, so that nearly the same metabolic homeostasis is achieved as under low nutrient availability, but at a higher biomass.
