title: Experimental plots studies comparing the impact of fertilization and wrack addition on invertebrate abundance and plant cover in Atlantic and Gulf of Mexico salt marshes from April 2009 to September 2010

description: Understanding the relative strengths of top-down and bottom-up forces is an important key to predicting the structure of biological communities. The strength of these effects can be regulated in part by predator abundance and nutrient availability. In 2009, we hypothesized that the importance of these factors varies geographically between the southeastern Atlantic Coast and the Gulf Coast due to differences in tidal regime, and began to study this variation using a biogeographic, manipulative field experiment. Although our original purpose was to understand the structure of salt marsh arthropod food webs, BP's Deepwater Horizon spill in the Gulf Coast presented an opportunity to understand how stress from an oil spill might affect the variables that we were measuring. The fact that we had plots and transect sampling in place at multiple sites along the Gulf and East Coasts put us in a position to evaluate any impacts that might occur if oil hit some of the sites. The study was conducted at 11 sites across the Gulf Coast, from Texas to Florida, and 11 sites along the Atlantic Coast, from Florida to Maine. At each site, experimental plots were sampled and a 100m transect was sampled near the plots within 5m of the high marsh boundary. Sampling was conducted in May 2009, August 2009, and August 2010. In 2010, four extra sites were added to the existing experimental sites because of known oil contamination, and another site was added as an extra control. Only the transect sampling was conducted at these sites. This dataset contains all the data from experimental plots; experimental treatments of fertilizer addition, wrack addition, fertilizer & wrack addition, and no addition (control) were randomly applied to the plots. The plot treatments were maintained in August 2009 and May 2010.

title: Invert species counts and density along transects on the high marsh along Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA.

description: At PIE, mummichog (Fundulus heteroclitus) use the spring-cycle high tides to access the flooded high marsh platform and consume invertebrate prey. Invertebrate surveys were conducted before and after spring tides that flooded the high marsh area to determine the effect of mummichog predation that occurs on the high marsh during the flood events and to assess the impact of low marsh geomorphology on top-down control by mummichog. These data were included in part of the study "Cross-habitat access modifies the ‘trophic relay’ in New England saltmarsh ecosystems” (Lesser et al. 2021) as well as a part of a NEU Three Seas Master's thesis.

title: PIE LTER herbivory measurement associated with marsh sites used in space for time sea level rise study, Rowley, MA.

description: This dataset contains aggregated observations of predation and herbivory on tethered bait in each quadrat of sites around the Rowley River and the south side of Sawyer Island at the Plum Island LTER. Measurements consist of the consumption status of tethered squid or kelp pieces as a measure of energy transfer between trophic levels. Pieces were left in the field for five days and observers recorded the status of bait over time as either entirely missing, partially consumed, having scrape marks, or fully intact. These measurements can be used to calculate consumption rates (i.e. energy transfer) over time. Notes include fields discussing any additional observations - e.g., if a stick was found missing.

title: Effects of mangrove encroachment on tidal wetland plants and epifauna: 2012-2020

description: Woody encroachment is occurring in many marsh-mangrove ecotones across the globe, with multiple drivers contributing to an increase in mangrove cover. As a result, marsh plant species are often displaced, resulting in a striking regime shift from grass and forb-dominated habitats to taller, woody vegetation. Our goal was to quantify the bottom-up effects of mangrove woody encroachment into coastal wetlands on associated plant and epifaunal assemblages. In 2012, we established several large (&gt; 20 ha) survey areas at tidal wetland sites with or without black mangroves (Avicennia germinans) on the Texas (USA) coast in the Gulf of Mexico, an area highly susceptible to mangrove encroachment. Starting in 2012, we annually recorded vascular plant cover and diversity and recorded snail (Littoraria irrorata) and fiddler crab (Uca spp.) density along transects perpendicular to the shoreline. Marsh plant species richness was 50% lower at sites with mangroves, and some species, such as Sarcocornia spp. and Distichlis spicata, were relatively rare or absent from sites with mangroves. The wetland plant communities at these sites were relatively unaffected by Hurricane Harvey (August 2017). Epifaunal snails and crabs were common at all sites, with abundances that varied over time. Our results indicate that coastal wetlands dominated by mangroves support different and lower diversity plant assemblages than marsh-dominated areas. These results were largely consistent with the results of a previous manipulative experiment in the same area. Therefore, as woody encroachment continues and mangrove cover gradually increases, this change may lead to complex bottom-up effects on a range of ecosystem processes and services.

title: Decades of water column temperature, lake level and meteorological data of Lake Lacawac, a pristine glacial lake at Lacawac Biological Field Station in the Pocono mountains, Pennsylvania USA (1992-2019)

description: Lake Lacawac weather and the lake water column were monitored to observe seasonal and interannual temperature and lake level patterns in response to solar heating, wind-driven water column mixing, precipitation, evaporation, watershed runoff and seepage, and outflow (L. Lacawac has an outflow stream but no inflow stream, and is surrounded on one side by peat bogs). Several studies have shown the lake to have a slow exchange by seepage (slightly more seeping in than out except during dry months). Over the years the raft data have been used to calibrate heat flux, mixing, and evaporation models for the lake, to study zooplankton and phytoplankton distribution and dissolved organic matter flux (photobleaching in the water column, influx from the watershed, and exchange with bottom sediments) and associated UV transparency. The data have also been used to accompany experimental manipulations of lake organisms (algae, zooplankton, fish) in relation to exposure to UV radiation. More recently these lake data have been useful in developing lake indices of climate change.

title: Arbuscular mycorrhizal fungal response to fire and urbanization in the Great Smoky Mountains National Park

description: Wildfires are increasing in frequency and intensity as drier and warmer climates increase plant detrital fuel loads. At the same time, increases in urbanization position 9% of fire-prone land within the US at the wildland-urban interface. While rarely studied, the compounded effects of urbanization and wildfires may have unknown synergistically negative effects on ecosystems. Previous studies at the wildland-urban interface often focus on aboveground plant communities, but belowground ecosystems may also be affected by this double disturbance. In particular, it is unclear how much fire and urbanization independently or interactively affect nutritional symbioses such as those between arbuscular mycorrhizal (AM) fungi and the majority of terrestrial plants. In November 2016, extreme drought conditions and long-term fire suppression combined to create a wildfire within the Great Smoky Mountains National Park (GSMNP) and the neighboring exurban city of Gatlinburg, TN. To understand how the double disturbance of urbanization and fire affected AM fungal communities, we collected fine roots from the five dominant understory species in September 2018 at each of 18 sites spanning three burn severities in both exurban and natural sites. Despite large variation in burn severity, plant species identity had the largest influence on AM fungi. AM fungal colonization, richness, and composition all varied most among plant species. Fire and urbanization did influence some AM fungal metrics; colonization was lower in burned sites and composition was more variable among exurban locations. There were no interactions among burn severity and urbanization on AM fungi. Our results point to the large influence of plant species identity structuring this obligate nutritional symbiosis regardless of disturbance regime. Therefore, the majority of AM fungal taxa may be buffered from fire-induced ecosystem changes if plant community composition largely remains intact, plant species life history traits allow for AM fungal persistence after fire disturbance, and/or nearby undisturbed habitat can act as an inoculum source for recolonization following fires. Thus, it is critical to maintain natural, undisturbed habitats interspersed within the wildland-urban interface.
