Each of these in turn can be separated into native and introduced (i.e., exotic) species. Although numerous studies have compared plant traits between the traditional groups of grasses and forbs, fewer have compared native versus introduced species. Introduced grass species, which were often introduced to prevent erosion or to improve grazing opportunities, have become common or even dominant species in grasslands. By virtue of their abundances, introduced species may alter ecosystems if they differ from natives in growth and allocation patterns. Introduced grasses were probably selected nonrandomly from the source population for forage (aboveground) productivity. Based on this expectation, aboveground production is predicted to be greater and root mass fraction to be smaller in introduced than native species. We compared root and shoot distribution and tissue quality between introduced and native C(4) grass species in the Blackland Prairie region of Central Texas, USA, and then compared differences to the more well-studied divergence between C(4) grasses and forbs. Comparisons were made in experimental monocultures planted with equal-sized transplants on a common soil type and at the same density. Aboveground productivity and C:N ratios were higher, on average, in native grasses than in native forbs, as expected. Native and introduced grasses had comparable amounts of shallow root biomass and tissue C:N ratios. However, aboveground productivity and total N were lower and deep root biomass and root mass fraction were greater in native than introduced grasses. These differences in average biomass distribution and N could be important to ecosystems in cases where native and introduced grasses have been exchanged. Our results indicate that native-introduced status may be important when interpreting species effects on grassland processes like productivity and plant N accumulation.", "keywords": ["580", "0106 biological sciences", "2.

At the individual  level, the effects of ecosystem engineers on other plants often become  more positive in stressful environments. In this study, we investigated  whether the community-level effects of ecosystem engineers also become  stronger in more stressful environments. Using comparative and  experimental approaches, we assessed the ability of a native shrub  (Ericameria ericoides) to act as an ecosystem engineer across a stress  gradient in a coastal dune in northern California, USA. We found increased  coarse organic matter and lower wind speeds within shrub patches. Growth  of a dominant invasive grass (Bromus diandrus) was facilitated both by  aboveground shrub biomass and by growing in soil taken from shrub patches.  Experimental removal of shrubs negatively affected species most associated  with shrubs and positively affected species most often found outside of  shrubs. Counter to the stress-gradient hypothesis, the effects of shrubs  on the physical environment and individual plant growth did not increase  across the established stress gradient at this site. At the community  level, shrub patches increased beta diversity, and contained greater  rarified richness and exotic plant cover than shrub-free patches. Shrub  effects on rarified richness increased with environmental stress, but  effects on exotic cover and beta diversity did not. Our study provides  evidence for the community-level effects of shrubs as ecosystem engineers  in this system, but shows that these effects do not necessarily become  stronger in more stressful environments.", "keywords": ["ecosystem engineers", "Stress-gradient hypothesis", "Anthropocene", "Bromus diandrus", "15.

We focused on plant diversity (measured as species richness and functional trait diversity) and, in addition, on soil organism diversity as a potential mediator for the relationship of plant species diversity and ecosystem functioning. Our results showed positive effects of plant diversity on soil multifunctionality and soil organic carbon stocks along the entire gradient. Structural equation models revealed that plant diversity enhanced soil multifunctionality and soil organic carbon by increasing the diversity of belowground organisms. These positive effects of plant diversity on soil multifunctionality and soil fauna were not restricted to native plant species only, but were also exerted by non-native species, although to a lesser degree. We conclude that enhancing diversity in plants and soil fauna of urban grasslands can increase the multifunctionality of urban soils and also add to their often underestimated but very valuable role in mitigating effects of climate change.", "formats": [{"name": "CSV"}], "keywords": ["Soil", "biodiversity", "urban areas", "field experimentation", "grasslands", "soil functions", "soil organic carbon", "invasive species", "opendata", "ecological novelty", "novel ecosystems", "Boden", "biodiversity", "urban ecology", "field experiment", "grassland", "soil function", "soil organism", "exotic species"], "contacts": [{"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' - WG Geodata", "roles": ["publisher"], "phones": [{"value": "+49 33432 82 171"}], "emails": [{"value": "bonares-datenzentrum@zalf.de"}], "addresses": [{"deliveryPoint": ["Eberswalder Strasse 84"], "city": "M\u00fcncheberg", "administrativeArea": "Brandenburg", "postalCode": "15374", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Schittko, Conrad", "organization": "Leibniz-Institut f\u00fcr Gew\u00e4sser\u00f6kologie und Binnenfischerei", "position": null, "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "Conrad.Schittko@igb-berlin.de"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": {"url": null, "protocol": null, "protocol_url": "", "name": "0000-0002-2200-8762", "name_url": "", "description": "ORCID", "description_url": "", "applicationprofile": null, "applicationprofile_url": "", "function": null}}]}, {"name": "Schittko, Conrad", "organization": "Leibniz-Institut f\u00fcr Gew\u00e4sser\u00f6kologie und Binnenfischerei", "position": null, "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "Conrad.Schittko@igb-berlin.de"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": {"url": null, "protocol": null, "protocol_url": "", "name": "0000-0002-2200-8762", "name_url": "", "description": "ORCID", "description_url": "", "applicationprofile": null, "applicationprofile_url": "", "function": null}}]}, {"organization": "Leibniz-Institut f\u00fcr Gew\u00e4sser\u00f6kologie und Binnenfischerei", "roles": ["contributor"]}]}, "links": [{"href": "https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&mid=3d41c738-2e57-4c9e-b81f-3a1cd7722f30", "rel": "information"}, {"rel": "self", "type": "application/geo+json", "title": "3d41c738-2e57-4c9e-b81f-3a1cd7722f30", "name": "item", "description": "3d41c738-2e57-4c9e-b81f-3a1cd7722f30", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/3d41c738-2e57-4c9e-b81f-3a1cd7722f30"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"interval": ["2017-04-18T00:00:00Z", "2018-04-30T00:00:00Z"]}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Exotic+species&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Exotic+species&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Exotic+species&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Exotic+species&offset=3", "hreflang": "en-US"}], "numberMatched": 3, "numberReturned": 3, "distributedFeatures": [], "timeStamp": "2026-09-20T21:05:02.923589Z"}
