Bird observations on the tidal flats of the Virginia Coast Reserve, 2016-2018
This dataset contains data on observations of birds on tidal flats along the Virginia portion of the Delmarva Peninsula, along the Atlantic side as part of the dissertation research of Alice Besterman. The first data table (ShorebirdswithZerosV1a.csv) has summary information on bird activities broken down by patch type and relation to tide. Shorebirds were surveyed on 9 intertidal mudflats from late April through end of May 2016. Surveys conducted within 3-5 hours of low tide. Scans last 15 minutes or less. Data table 2 (2018_patchscale_long.csv) contains data from surveys of shorebirds on 36 intertidal mudflats. Surveys conducted in May 2018 at low tide. Tidal flats were visited a single time, and scanned a single time. Scans lasted 15 minutes or less. Only target species were counted and microhabitat-use was recorded. A "wide" version of the data with columns of species/cover is also provided as a .zip file. Data table 3 (ContinSampFinala.csv) contains data collected during focal behavioral observations of shorebirds on intertidal mudflats. Data were collected from 9 sites in 2016 between late April and the end of May during low tide. Observations lasted up to 3 minutes or less if observer lost sight of the bird or bird left the site. Data table 4 (allbirds2a.csv) contains surveys of shorebirds using mudflats in May 2018. Sites were visited a single time during low tide. Tidal flats were scanned a single time, and scans lasted 15 minutes or less. This data table differs from Data table 2 in that all shorebird species of interest were counted (not just target species for behavioral analyses), and microhabitat-use data were not included. Data table 5 (InstantSampFinala.csv) contains data collected during focal behavioral observations of shorebirds on intertidal mudflats. Data were collected from 9 sites in 2016 between late April and the end of May during low tide. Observations lasted up to 3 minutes or less if observer lost sight of the bird or bird left the site.
Invertebrates on the tidal flats of the Virginia Coast, May 2016
Invertebrate composition, size and mass measurements were taken on tidal flats on the Virginia Coast. Data table 1 (Invertebrates2016a.csv): Invertebrates collected from mudflats during May 2016. Cores were 15 cm inner diameter and 10 cm deep, all epifauna and infauna collected. If cores were collected from macroalgal patch then macroalgae and epifauna were also taken. Data table 2 (InvCleanwZerosa.csv): Abundances and weights of invertebrates collected from mudflats May 2018. Cores were 7 cm inner diameter and 7 cm deep. Eight cores were collected per site from randomly selected sampling locations along a 120 m transect. 600 micron mesh used, all epifauna and infauna within core area collected. Data table 3 (Site_codes_Lat_Lon_2016_2018.csv): contains location information on sampling sites during 2016 and 2018.
Benthic Chlorophyll and Macroalgae on an Experimentally-manipulated Tidal Flat on the Virginia Coast, 2016-2017
In 2016 a Before-After-Control-Impact experimental design was used to test if the removal of macroalgae from a heavily vegetated mudflat would result in an increase in MPB biomass (Smith 2002). Data Table 1 (BCL_BACIexpa.csv):Benthic chlorophyll samples collected from mudflat where experimental macroalgal removal was conducted. Samples collected haphazardly from 3500 m^2 plots. Sediment cores were 1 cm inner diameter and 2 cm deep. Data Table 2 (BCL_MAMPBa.csv):Survey data where macroalgal mats were sampled and sediment beneath mats sampled for benthic chlorophyll. This data table contains benthic chlorophyll data. Corresponding macroalgal mass data found in MAmass_MAMPBa.csv. Sediment cores were 1 cm inner diameter and 2 cm deep. Three subsamples taken (A,B,C). Data Table 3 (MAmass_MAMPBa.csv): Survey data where macroalgal mats were sampled and sediment beneath mats sampled for benthic chlorophyll. This data table contains macroalgal mass data. Corresponding chlorophyll data found in BCL_MAMPBa.csv
Data from: Recovery of macrobenthic communities in tidal flats following the Great East Japan Earthquake
<p><span>Extreme geo-climatic events can occur everywhere in the world. The Great East Japan Earthquake, with a moment magnitude scale of 9.0 M on March 11, 2011, was one of these events and caused huge tsunamis that changed largely tidal communities on the Pacific coast of eastern Japan. However, subsequent long-term changes in the communities after such an extreme geo-climatic event have rarely been examined. Therefore, we performed the biological monitoring over a ten-year span, before and after the earthquake, that was supported by citizen volunteers. The results revealed that the most tidal communities returned to their original states in less than a decade, indicating that the nearshore communities were highly resilient to large physical disturbances like tsunamis if the surrounding environmental conditions were unchanged.</span></p>

Human-wildlife interactions on the tidal flats of the Bijagós archipelago: does shellfishing affect migratory shorebirds?
<p>The Bijagós archipelago in West Africa is home to an ethnic group with a rich cultural heritage that is tightly linked to nature. The Bijagós people have a shared cultural identity, but across islands, there are different resource management regimes stemming from island-specific context with regards to socio-political organization and strength of cultural heritage. Across the archipelago, bivalves harvested manually from the mudflats are an important part of the Bijagós people's diet, economy, and culture. Thousands of migratory shorebirds share the use of these mudflats during their non-breeding season, consuming macrobenthos such as crustaceans and bivalves, including those harvested by local people. At the end of their stay in the Bijagós, shorebirds need to fuel for their migratory flight in order to return to their breeding areas, being particularly important during this period that they have access to undisturbed feeding areas with suitable food resources.</p> <p>In this study, we start by exploring shellfishing patterns across different management regimes, then assess seasonal variation in the direct impact of shellfishing on shorebirds (through competition for resources and space), and finally quantify the indirect impact of sediment disturbance due to shellfishing upon shorebird prey availability. Results indicate that bivalve resources are better managed in areas with formal protection, while traditional management based on cultural beliefs results in poorer stock conditions. Interestingly, across islands shellfishing activity is concentrated in mid-winter, decreasing towards shorebirds' fuelling period, when they benefit the most from reduced disturbance on the mudflats. No direct competition for resources was detected, as collected bivalves were significantly larger than those consumed by shorebirds, regardless of the season. Indirect impacts caused by sediment disturbance during shellfishing were also mostly absent, causing only a small reduction on shorebirds prey density, but with no effect on the available biomass.</p>
