Ecosystems worldwide are rapidly losing taxonomic, phylogenetic, genetic, and functional diversity as a result of human appropriation of natural resources, modification of habitats and climate, and the spread of pathogenic, exotic, and domestic plants and animals. /MediaBox [0 0 612 792] /Type /Page  This trait, unique to Agrobacterium fabrum, allowed it to avoid competition with closely related bacteria in Agrobacterium found within the same environment. /Author (cwb)  Increased functional diversity increases both the capacity of the ecosystem to regulate the flux of energy and matter through the environment (Ecosystem Functions) as well as the ecosystem's ability to produce resources beneficial to humans such as air, water, and wood (Ecosystem Services). /Rotate 0 /XObject << /CropBox [0 0 612 792] 'Guilds' would be re-termed 'functional groups', and classification schemes began to focus more on interactions between species and trophic levels.

This 'detection filtering' has major consequences on functional packaging and the defining functional groups in an ecosystem. /Resources 69 0 R We propose 2 complementary approaches to assessing a species’ ecological functions: confirmation (listing interactions of the species, identifying ecological processes and other species involved in these interactions, and quantifying the extent to which the species contributes to the identified ecological process) and elimination (inferring functionality by ruling out symptoms of reduced functionality, analogous to the red‐list approach that focuses on symptoms of reduced viability). /Producer (Acrobat Distiller 5.0 \(Windows\)) /MediaBox [0 0 612 792] endobj /Filter /FlateDecode /Type /Page /Contents 72 0 R /MediaBox [0 0 612 792] >>  Under this paradigm, functional traits are defined as morpho-physiophenological traits which impact fitness indirectly via their effects on growth, reproduction and survival. /SMask 93 0 R  Notice that is definition is not specific to species. /Contents 68 0 R >>  Ecosystem Functions are drastically reduced with decreases in the diversity of genes, species and functional groups present within an ecosystem. /MediaBox [0 0 612 792] 19 0 obj /CropBox [0 0 612 792] 13 0 obj >> If this process can be shown to generalize, then the ecological functions of other organisms can be inferred simply from genetic information. ecological role) of a plant so that it could avoid competing with its close relatives. endobj /Contents 70 0 R /CropBox [0 0 612 792]  In the 1990s, biodiversity became better understood as the diversity of species' ecological functions within an ecosystem, rather than simply a great number of different species present. Así, conecta e integra la conservación a nivel de especies y ecosistemas. , The notion that ecosystems' functions can be affected by their constituent parts has its origins in the 19th century. This vision focuses on conservation and recovery at the species level and sees species as embedded in ecosystems, influencing and being influenced by the processes in those ecosystems. Su visión se centra en la conservación y recuperación a nivel de especies y ve a las especies como componentes de los ecosistemas, influyendo y siendo influenciadas por los procesos en esos ecosistemas.  For example, when averaged over an ecosystem, individual plants' heights can contribute to ecosystem productivity or efficiency..  To avoid reintroducing a species that is rendered functionally redundant by one of its ancestors, a functional analysis of global ecosystems can be performed to determine which ecosystems would benefit most from the added functional diversity of the reintroduced species. /BM /Normal endobj /Type /Page Species interactions matter to conservation.
