Functional diversity on rocky shores of the SW Atlantic: sewage effluents influence and mask the effects of the latitudinal gradient. Trait‐based numerical classification of mesic and wet grasslands in Poland. Testing predictions of resistance and resilience of vegetation subjected to extreme events. In fact, birds, bats, and butterflies play a vital role in spreading pollen and in dispersing seeds. boreal forests, bogs and heathland) or species‐rich ecosystems (e.g. First, we need to know whether losses in species richness have immediate (proximal) effects on ecosystem function. Does the leaf economic spectrum hold within plant functional types? Linking vegetation and soil functions during secondary forest succession in the Atlantic forest. With the coyotes gone, deer mice, the coyotes' prey, flourished and overproduced. Using proxies of microbial community‐weighted means traits to explain the cascading effect of management intensity, soil and plant traits on ecosystem resilience in mountain grasslands. The control of relative abundance in communities of herbaceous plants. Regeneration and pattern in the sub tropical rain forest. Fundamental to the success of these communities is their vast diversity which enables them to adapt to changing conditions. Dominants recur in particular vegetation types, are relatively large, exhibit coarse‐grained foraging for resources and, as individual species, make a substantial contribution to the plant biomass. This suggests that within the majority of herbaceous vegetation samples three elements can be recognized, each capable of varying in species richness and taxonomic identity, and here described as dominants, subordinates and transients. Temporal and dietary niche is context‐dependent in tropical ants. Following Egler (1954) we may suspect that the speed and completeness with which ecosystem re‐assembly occurs will depend upon early colonization by appropriate dominants and subordinates; late arrival may be expected to delay establishment of a species and may even exclude some completely (Keever 1950; Niering & Goodwin 1962; Holt 1972; Platt 1975). Average leaf litter quality drives the decomposition of single-species, mixed-species and transplanted leaf litters for two contrasting tropical forest types in the Congo Basin (DRC). The fate of seed and transplants introduced into various habitats. Light mediates the relationship between community diversity and trait plasticity in functionally and phylogenetically diverse tree mixtures. From abundance-based to functional-based indicator species. Temporal stability of grassland metacommunities is regulated more by community functional traits than species diversity. Control of relative abundance of perennials in chalk grassland in southern England. For European herbaceous vegetation, there is an enormous fund of information on the abundance and characteristics of component species in relatively small (c. 1 m2) vegetation samples. 5 Transients originate from the seed rain and seed banks and provide an index of the pool of potential dominants and subordinates at specific sites. We may conclude, therefore, that functional diversity among dominants and perhaps also within subordinates is capable of immediate impacts on the properties of ecosystems. Localized defense induction in trees: a mosaic of leaf traits promoting variation in plant traits, predation, and communities of canopy arthropods?. The benefits of biodiversity include keeping water quality pure. And the more closer a species is related to another, the more genetic information the two species will share. 1 It is useful to distinguish between the immediate effects of species richness on ecosystems and those which become apparent on a longer time scale, described here as filter and founder effects. In a system where species are limited, the loss or temporary reduction of any one could disrupt a complex food chain with serious effects on other species in that … The term "biodiversity" literally indicates the diverse biological species within an ecosystem. Long‐term Impacts of Permafrost Thaw on Carbon Storage in Peatlands: Deep Losses Offset by Surficial Accumulation. The effects of mowing and multi-level N fertilization on soil bacterial and fungal communities in a semiarid grassland are year-dependent. The Ecology of Natural Disturbance and Patch Dynamics. Per‐gram competitive effects and contrasting soil resource effects in grasses and woody plants. Ecology of Biological Invasions of North America and Hawaii, Pattern and Process in a Forested Ecosystem, Plant Sociology: the Study of Plant Communities. Pollinators, including bees and butterflies, provide significant environmental and economic benefits to agricultural and natural ecosystems, including adding diversity and productivity to food crops. According to this hypothesis the significance of plant diversity in relation to deterioration of ecosystem functions may arise primarily from its effects on the recruitment of dominants rather than any immediate effects of species richness per se. They occur as scattered individuals and many appear only briefly as seedlings that fail to survive. Factors controlling drought resistance in grapevine (Vitis vinifera, chardonnay): application of a new microCT method to assess functional embolism resistance. Awareness of biodiversity has recently led to a boom in ecotourism. When attention is turned to other trophic elements, such as parasites, herbivores, predators and symbionts, the possibility arises for ecosystem impacts that are less predictably related to abundance. The benefits of biodiversity include keeping water quality pure. europa.eu Sie … More often complementarity between dominants and subordinates consists of circumstances in which the latter exploit relatively unfavourable microhabitats. Resource enrichment combined with biomass removal maintains plant diversity and community stability in a long-term grazed grassland. Biodiversity helps to moderate the elements, reducing utility bills and preventing large-scale damage. Ecological studies in the Connecticut Arboretum Natural Area. These are abundant in the Appalachians, from clean drinking water and sustainably harvested forest products to nature-based tourism. We may predict that a diversity of transients signifies the presence of a rich assortment of colonizers and a high probability that, in the event of habitat disturbance or changes in management, there will be a rapid ingress of different plant functional types, some of which may be capable of exploiting the new conditions. Nitrate losses from disturbed forests; patterns and mechanisms. Dominant and subordinate components of plant communities – implications for succession, stability and diversity. 4 Attribution of immediate control to dominants does not exclude subordinates and transients from involvement in the determination of ecosystem function and sustainability. An ecosystem is in perfect balance, with a keystone species that basically holds the ecosystem in that balance. Higher tree diversity increases soil microbial resistance to drought. Parasites, diversity and the ecosystem. Multiple facets of marine biodiversity in the Pacific Arctic under future climate.
