For the past 20 years, research on biodiversity and ecosystem functioning (B-EF) has only implicitly considered the underlying role of environmental change. We illustrate that explicitly reintroducing environmental change drivers in B-EF research is needed to predict the functioning of ecosystems facing changes in biodiversity. Next we show how this reintroduction improves experimental control over community composition and structure, which helps to provide mechanistic insight on how multiple aspects of biodiversity relate to function and how biodiversity and function relate in food webs. We also highlight challenges for the proposed reintroduction and suggest analyses and experiments to better understand how …
Estimated Losses Of Plant Biodiversity Across The U.S. From Historical N Deposition From 1985—2010., Christopher M. Clark, Philip E. Morefield, Frank S. Gilliam, Linda H. Pardo
Estimated Losses Of Plant Biodiversity Across The U.S. From Historical N Deposition From 1985—2010., Christopher M. Clark, Philip E. Morefield, Frank S. Gilliam, Linda H. Pardo
Frank S. Gilliam
Although nitrogen (N) deposition is a significant threat to herbaceous plant biodiversity worldwide, it is not a new stressor for many developed regions. Only recently has it become possible to estimate historical impacts nationally for the United States. We used 26 years (1985–2010) of deposition data, with ecosystem-specific functional responses from local field experiments and a national critical loads (CL) database, to generate scenario-based estimates of herbaceous species loss. Here we show that, in scenarios using the low end of the CL range, N deposition exceeded critical loads over 0.38, 6.5, 13.1, 88.6, and 222.1 million ha for the Mediterranean …
15. The Conservation Significance Of Prairie Remnants In Missouri, Bruce Schuette
15. The Conservation Significance Of Prairie Remnants In Missouri, Bruce Schuette
North American Prairie Conference Proceedings
How to conserve the great biodiversity of the prairie resource is a question of continuous debate. In Missouri the estimated 6,070,284 ha (15 million acres) of prairie at the time of Euro-American settlement has been reduced to an estimated 20,234–24,281 ha (50,000–60,000 acres) today, with 8,093 ha (20,000 acres) in conservation ownership. This valuable resource is rare now and is continuing to disappear. The Missouri Prairie Foundation (MPF), a nongovernmental organization celebrating its 50th anniversary in 2016, has acquired and protects 22 tracts that cover more than 1,335 ha (3,300 acres), comprised mostly of original unplowed prairie. These parcels, though …

New Or Additional Cladoniicolous Fungi For Turkey, Mustafa Kocakaya, Mehmet Gökhan Halici, Raquel Pino Bodas
Turkish Journal of Botany
This study reports twelve species of cladoniicolous fungi from Turkey. Nine of these taxa, i.e. Abrothallus cladoniae R.Sant. And D.Hawksw., Epicladonia stenospora (Harm.) D.Hawksw., Lichenosticta alcicornaria (Linds.) D.Hawksw., Lichenoconium aeruginosum Diederich, M.Brand, van den Boom and Lawrey, Phoma foliaceiphila Diederich, Kocourk. And Etayo, Scutula cladoniicola Alstrup and D.Hawksw., Sphaerellothecium cladoniicola E.S. Hansen and Alstrup, Syzygospora bachmannii Diederich and M.S.Christ., and Taeniolella beschiana Diederich, are new records for Turkey. A key to these 12 species of lichenicolous fungi on Cladonia species is provided.

Haematococcus: A Successful Air-Dispersed Colonist In Ephemeral Waters Is Rarely Found In Phytoplankton Communities, Savvas Genitsaris, Natasa Stefanidou, Matina Katsiapi, Elisabeth Vardaka, Konstantinos Ar. Kormas, Ulrich Sommer, Maria Moustaka-Gouni
Haematococcus: A Successful Air-Dispersed Colonist In Ephemeral Waters Is Rarely Found In Phytoplankton Communities, Savvas Genitsaris, Natasa Stefanidou, Matina Katsiapi, Elisabeth Vardaka, Konstantinos Ar. Kormas, Ulrich Sommer, Maria Moustaka-Gouni
Turkish Journal of Botany
In a literature search, the presence of Haematococcus in phytoplankton communities and its biogeography were investigated. Haematococcus, although showing a wide biogeographical distribution, has been rarely found in phytoplankton communities. Simultaneously, the colonization potential of air-dispersed Haematococcus in ephemeral waters and its interactions with coexisting phytoplankton taxa were examined by microscopy and molecular methods. Haematococcus was a successful colonist, appearing among the first taxa in the experimental containers. According to principal component analysis, Haematococcus growth rate was negatively correlated with the abundance and species richness of the other autotrophs. Furthermore, a negative correlation between Haematococcus and Chlamydomonas and a positive …
Invasive Plant Ecology In Vermont: Insights From Spatial Analysis And Interactions Of Garlic Mustard (Alliaria Petiolata) With Native Plants And Invertebrates, Chenin Kathleen Limback
Invasive Plant Ecology In Vermont: Insights From Spatial Analysis And Interactions Of Garlic Mustard (Alliaria Petiolata) With Native Plants And Invertebrates, Chenin Kathleen Limback
Graduate College Dissertations and Theses
Causes and patterns of invasive plant species establishment and success depend broadly upon their ecology, including habitat suitability and interactions with other plants and animals. Here I examine the traits and distribution of invasive plants in Vermont, using spatial analysis, laboratory and field studies. I used GIS to investigate environmental factors correlated with presence of 19 invasive plant species in Vermont campgrounds. My results support the assumption that human dispersal of invasive plant seed and stock may be more important than natural dispersal of these plant species to new sites. I also investigate in-depth the relationships of invasive herbaceous garlic …
