PIE LTER, Hach, OTT RLS measurements of water column depth at 15 minute intervals in the lower Plum Island Sound off the Ipswich Bay Yacht Club pier, Ipswich, MA, year 2018
Measurements of water column depth at 15 minute intervals in Plum Island Sound at the Ipswich Bay Yacht Club, for year 2018. OTT radar level sensor (RLS) installed September 20, 2011 out of the water under the concrete pad on the Ipswich Bay Yacht Club pier, Ipswich, MA. RLS was mounted so that continuous year round measurements can be conducted without the concern of ice flows damaging the sensor.
Biomass of Spartina alterniflora collected in July 2018 from various marsh edges around Plum Island Sound, MA, PIE LTER.
Biomass of Spartina alterniflora was collected at various locations within the Plum Island Sound estuary. Samples were collected during July 2018. Only Spartina alterniflora was collected. To collect biomass, 25 X 25 cm quadrats were placed over the plants. Aboveground biomass was clipped to soil surface. Biomass was dried in the lab in a drying oven until a constant weight was reached, and then weighed. Biomass values were then convertedto grams of dry weight per square meter (g/m2).
PIE LTER extensometer measurements of marsh bank sediment deformation, soil creep in West Creek, Rowley, MA.
Muddy banks of marsh channels experience soil creep – a viscous-like slow deformation resulting in a net downslope transport. Here we present the first field evidence of soil creep in a mesotidal salt marsh using high precision measurements of soil deformation taken with a vibrating-wire extensometer over two years.

Fiddler crab body size in salt marshes from Florida to Massachusetts, USA at PIE and VCR LTER and NOAA NERR sites during summer 2016.
Bergmann’s rule predicts that organisms at higher latitudes are larger than ones at lower latitudes. Here, we examine the body-size pattern of the Atlantic fiddler crab, Minuca (=Uca) pugnax, from salt marshes on the east coast of the United States across 12 degrees of latitude. We found that M. pugnax followed Bergmann’s rule and that, on average, crab carapace width increased by 0.5 mm per degree of latitude. Minuca pugnax body size also followed the temperature-size rule with body size inversely related to mean water temperature. Because an organism’s size influences its impact on an ecosystem, and Minuca pugnax is an ecosystem engineer that affects marsh functioning, the larger crabs at higher latitudes may have greater per-capita impacts on salt marshes than the smaller crabs at lower latitudes.
PIE LTER diel surface water chemistry of two high marsh ponds, Rowley, MA, during the summer of 2016.
We measured diel fluctuations in surface water chemistry of two high marsh ponds in July 2016. The ponds are shallow and experience day-night swings in oxygen concentrations, from super-saturation to anoxia. Our goal was to characterize changes in geochemical properties and dissolved organic carbon concentrations that accompany wide swings in oxygen concentrations. These data provide information about the responsiveness of microbial communities and how the dominance of redox-sensitive metabolisms changes over short time scales (e.g., hours) to feed back on pond water chemistry.
PIE LTER benthic microalgal biomass in fiddler-crab plots in a salt marsh of West Creek, Rowley, MA.
It is well known that species across the world are expanding or shifting their ranges because of climate change. Yet, we know little about their impact on the habitats they colonize. In an observational study, we examined the effect of the fiddler crab Minuca pugnax (Smith, 1870) on benthic microalgal biomass in salt marshes in its expanded range (northeastern Massachusetts, USA). We found that plots with M. pugnax had, on average, 74% lower diatom biomass and 77% lower cyanobacteria biomass than plots without M. pugnax. Our results indicate that this climate migrant can impact saltmarsh functioning by limiting benthic microalgal biomass. See: Johnson, D.S., K.S. Martínez-Soto, S. Wittyngham, M. Pant, and E. Goetz. 2020. The fiddler crab Minuca pugnax (Smith, 1870) (Decapoda: Brachyura: Ocypodidae) reduces saltmarsh algae in its expanded range. Journal of Crustacean Biology 40: 668-672
PIE LTER, parasites of the fiddler crab, Minuca pugnax, on east coast salt marshes of the USA.
When a species colonizes a new range, it can escape enemies found in its original range. Examples of enemy escape abound for invasive species, but are rare for climate migrants, which are populations of a species that colonize a new range due to climate-driven range shifts or expansions. The fiddler crab Minuca (=Uca) pugnax is found in the intertidal salt marshes of the US east coast. It recently expanded its range north into the Gulf of Maine as a result of ocean warming. We tested the hypothesis that M. pugnax had escaped its parasite enemies. Parasite richness and trematode intensity were lower in populations in the expanded range than in populations in the historical range, but infection prevalence did not differ. Although M. pugnax escaped most of its historical parasites when it migrated northward, it was infected with black-gill lamellae (indicative of Synophrya hypertrophica), which was found in the historical range, and with the trematode Odhneria cf. odhneri, which was not found in the historical range. To our knowledge, this is the first time that O. cf. odhneri has been reported in fiddler crabs. These results demonstrate that although M. pugnax escaped some of its historical parasites when it expanded its range, it appears to have gained a new parasite (O. cf. odhneri) in the expanded range. Overall, our results demonstrate that climate migrants can escape their enemies despite colonizing habitats adjacent to their enemy-filled historical range. See Johnson et al. 2020. A climate migrant escapes its parasites. Marine Ecology Progress Series 641: 111-121 for more details.
