ecosystem diversity pdf

A key challenge is to quantify the functional roles of microbial taxa to understand how ecosystem properties change at spatial and temporal scales. Ecosystem diversity defines patterns of natural variability that shape species distribution and abundance, resilience, and natural ecosystem functioning (Junk et al. 2005). View AP ES-009 Ecosystem Diversity CM.pdf from BIOLOGY 20008201 at King High School. They examine forests by biological type and also by tenure, and record the area of each type. For example, a coral reef ecosystem, composed of coral, sea stars, worms, sea slugs, snails, kelp, sea grass, fish, crabs, sharks, seals, whales, and plankton has much greater ecosystem diversity than the open ocean near Antarctica, which has an ecosystem composed primarily of phytoplankton, krill, fish, and whales. For example, there are desert ecosystems and marine ecosystems, forest ecosystems and pond ecosystems, to name but a few. Explanation Ecosystem Biodiversity is further divided into three parts i) Alpha Biodiversity, ii) Beta Biodiversity iii) Gamma Biodiversity Biodiversity is the variety and variability among living organisms and the ecological complexes on the … Ecosystem ACRONYMS AREAS COUNTRIES MARINE TERMS DEFINITION A dynamic complex of plant, animal and micro-organism communities and their non- living environment interacting as a functional unit. The indicators for ecosystem diversity are stand level habitat composition and priority habitat types. Figur e 11.1 Biodiversity Genes: The basic biological unit of heredity . 1989, Poff 1997, Thorp et al. the effects of diversity on multiple ecosystem functions [8–15]. Woody plant species diversity as a predictor of ecosystem services in a social–ecological system of southwestern Ethiopia Girma Shumi . Ecosystem Diversity. Ecosystem diversity refers to the variety of habitats, communities and ecological processes within an ecosystem and between different ecosystems. species turnover and nestedness) may relate to ecosystems function. There is consensus that greater biodiversity is essential to maintain the ecosystem function and stability. climate or the availability of suitable food and shelter) that make it especially well suited to meet the life cycle needs of that species. AP Environmental Science - 009 Ecosystem Diversity variety Biodiversity Life of Species Ecosystem Plants and animals constitute only a small component of biodiversity . Convention on Biological Diversity 1992[1] KEY POINTS Ecosystems are the smallest unit of a living system which is functionally independent. Werner Ha¨rdtle . ecosystem performance, including providing ecosystem ser-vices, as diversity increases the chances that one or more species will be able to perform critical functions, even in the event of disturbance or species loss (e.g., natural disaster and human-induced land use change) (Naeem and Li, 1997). Jan Hanspach . It includes diversity within and among species and diversity within and among ecosystems. Species diversity, functional diversity and ecosystem functioning. ecosystem services concept provides a starting point towards defining, monitoring and valuing such services. Eva Spehn Variation in spatial plant community heterogeneity (β diversity) affects productivity and ecosystems function; however, relatively few studies have addressed how β diversity and its components (i.e. Kristoffer Hylander . It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Ecosystem diversity refers to different habitats such as temperate or tropical forests, mountains, cold and hot deserts, oceans, wetlands, rivers and coral reefs. Let us take each one of them in turn. Do you know that the invisible micro-or ganisms constitute a lar ge component of bio-diversity . on Biological Diversity and endorsed by other biodi-versity-related conventions, was intended as a global framework for all sections of society – and its success would depend on bringing about change among a wide range of sectors and stakeholders whose decisions and actions have an impact on biodiversity. Ecosystem diversity refers to the number of di fferent ecosystem types and their areal distribution at various ecosystem levels. The Earth has many diverse ecosystems and ecologicalsystem diversity. Maintaining native ec osystem diversity is fundamental to maintaining terrestrial ecosystem functions and overall ecosystem health. diversity–ecosystem function experiment, Kirwin and colleagues (2007) showed that species richness affected ecosystem function more strongly in polycultures with high evenness. These are NASA composite images of the Earth: 2001 (left), 2002 (right), titled The Blue Marble. Each ecosystem is characterized by complex relationships between living components such as plants and animals and non-living components such as soil, air and water. However, well-replicated biomass in plots with greater plant diversity. A series of studies have demonstrated that high levels of species richness are important for sustaining multiple functions and services, and thus a loss of species can adversely affect the functionality of ecosystems. 2016). Furthermore, AMF diversity correlated with ecosystem multifunctionality under nutrient addition worldwide. The ecosystem principle of diversity, when considered in industrial environmental policy and management, could then mean diversity in cooperation. microbial diversity and ecosystem function in relation to functional diversity. A study of insect diversity in different peatland ecosystem was held in Betong Division, Sarawak. Ecosystem Diversity - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. between microbial diversity and ecosystem functions in natural ecosystems and across broad environmental contexts (Soliveres et al. Ecosystem diversity can mean two things. Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Biodiversity is the source of many ecosystem goods, such as food and genetic resources, and changes in biodiversity can influence the supply of ecosystem services. However, evidence suggests that FREs and Glomeromycota have different interactions with the environment and may be functionally distinct. Our findings identify the negative effects of nutrient enrichment on AMF and plant diversity and suggest that AMF diversity is closely linked with ecosystem function. Recent genetic diversity–ecosystem function (GD-EF) research has demonstrated that genetic variation within plant species (such as genotypic or allelic richness as reviewed in Hughes et al. Ecosystem & Diversity .pdf - Free download as PDF File (.pdf), Text File (.txt) or read online for free. IEs. abundant within ecosystems, we know almost nothing about the diversity, ecology or ecosystem function of the fungi involved. Genetic Diversity, Species Diversity & Ecosystem Diversity are types of Biodiversity.Biodiversity is of mainly three types which are above mentioned. Functional trait diversity maximizes ecosystem multifunctionality Nicolas Gross1, 2, 3 †*, Yoann Le Bagousse-Pinguet1 †*, Pierre Liancourt4 †*, Miguel Berdugo1, Nicholas J. Gotelli5 and Fernando T. Maestre1 Understanding the relationship between biodiversity and ecosystem functioning has been a core ecological research topic over the past decades. A habitat is the environment in which an organism or species lives and includes the physical characteristics (e.g. These GD effects can also extend to affect diversity of higher trophic levels (Wimp et al. 2008) has consequences for plant communities (Booth & Grime 2003; Fridley & Grime 2009). Ecosystem diversity is a term that incorporates both habitat and community diversity. 2006). Greater ecosystem stability at higher diversity meant ecosystem stability but lower species stability, much as predicted by there was lower proportional change in the annual production of models of multispecies competition8,19. Patrı´cia Rodrigues . Joern Fischer . Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community. The existence of diverse and interdependent cooperation systems could for example facilitate the existence of systems, where the actors involved use each other’s waste materials and energy through cooperation, i.e. Feyera Senbeta . The Importance of β-Diversity for Understanding the Causes and Consequences. diversity-dependent ecosystem processes and services.Among these global change drivers, a major threat to biodiversity-dependent human well-being is large-scale land use change, especially the intensification and extensi-fication associated with large-scale industrial agriculture (high certainty). Firstly, ecosystem can refer to the fact that there are several diverse types of ecosystem out there in the world. diversity , (ii) species diversity and (iii) ecosystem diversity . The diversity and relative abundances of species should be important only when species differ in niche requirements or their functional contribution to the ecosystem (Nijs and Roy 2000, Mouillot et al. Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. 2002. There are three indicators in this section.
