Anthropogenic transformation of the terrestrial biosphere.
Human populations and their use of land have transformed most of the terrestrial biosphere into anthropogenic biomes (anthromes), causing a variety of novel ecological patterns and processes to emerge. To assess whether human populations and their use of land have directly altered the terrestrial biosphere sufficiently to indicate that the Earth system has entered a new geological epoch, spatia...
متن کاملMicrobial Ecology: Finding Structure in the Rare Biosphere
Protists (unicellular eukaryotes) play important roles in marine ecosystems but are tremendously diverse and many remain uncharacterized. Deep-sequencing of a universal marker gene has helped resolve community composition patterns among rare and abundant protistan sequence groups in coastal European waters.
متن کاملAnthropogenic noise's first reverberation into community ecology.
Humans are noisy. Indeed anthropogenic sounds are now eutrophication [5]), or by directly manipulating their almost ubiquitous throughout the land and seas [1]. Much recent work has focused on how noise affects the presence, abundance and behaviour of animals, either through directly harming animals or by making it difficult for them to communicate (e.g. [2]). A recently published study of Fran...
متن کاملEcology of the rare microbial biosphere of the Arctic Ocean.
Understanding the role of microbes in the oceans has focused on taxa that occur in high abundance; yet most of the marine microbial diversity is largely determined by a long tail of low-abundance taxa. This rare biosphere may have a cosmopolitan distribution because of high dispersal and low loss rates, and possibly represents a source of phylotypes that become abundant when environmental condi...
متن کاملPlant ecology. Anthropogenic environmental changes affect ecosystem stability via biodiversity.
Human-driven environmental changes may simultaneously affect the biodiversity, productivity, and stability of Earth's ecosystems, but there is no consensus on the causal relationships linking these variables. Data from 12 multiyear experiments that manipulate important anthropogenic drivers, including plant diversity, nitrogen, carbon dioxide, fire, herbivory, and water, show that each driver i...
