Inventory and Assessment of Wisconsin's Baraboo Hills Country (USA) as an Aspiring UNESCO Global GeoparkNARA Subscribed
We analyzed the Baraboo Hills in south-central Wisconsin (USA) as a first step in consideration of its potential for UNESCO Global Geopark designation. Well over 200 Geoparks exist around the globe; presently none are in the USA. The basis for designation is a geographical area that contains geological heritage of international significance, but a Geopark’s fuller mission according to UNESCO is to “explore, develop and celebra...
Terrigenous inputs link nutrient dynamics to microbial communities in a tropical lagoonNARA Subscribed
Nutrient availability drives community structure and ecosystem processes, especially in tropical lagoons that are typically oligotrophic but often receive allochthonous inputs from land. Terrestrially derived nutrients are introduced to tropical lagoons by surface runoff and submarine groundwater discharge, which are influenced by seasonal precipitation. However, terrigenous inputs presumably diminish along the onshore–offshor...
Pine invasions lead to losses of native biodiversity and ecosystem function, but pine invasion success is often linked to coinvading non‐native ectomycorrhizal (EM) fungi. How the community composition, traits, and distributions of these fungi vary over the landscape and how this affects pine success is understudied. A greenhouse bioassay experiment was performed to test the effects of changes in EM fungal community structure...
The negative effects of deforestation can potentially be ameliorated through ecological restoration. However, reforestation alone may not reassemble the same ecological communities or functions as primary forests. In part, this failure may be owed to forest ecosystems inherently involving complex interactions among guilds of organisms. Plants, which structure forest food webs, rely on intimate associations with symbiotic micro...
Observations of pigment and particle distributions in the western North Atlantic from an autonomous float and ocean color satelliteNARA Subscribed
Profiling floats with optical sensors can provide important complementary data to satellite ocean color determinations by providing information about the vertical structure of ocean waters, as well as surface waters obscured by clouds. Here we demonstrate this ability by pairing satellite ocean color data with records from a profiling float that obtained continuous, high‐quality optical data for 3 yr in the North Atlantic Ocea...
