Neritina snails responses to channel realignment
This data set includes N. virginea densities and sizes relative to streambed substrate type, water depth, and near-bed water velocity in three sites in a low land segment in RÃo Mameyes near PR Route 3 bridge: 1) 50 m upstream from bridge, 2) immediately downstream from bridge, and 3) 200 m downstream from bridge (upper Westin Riomar Golfcourse). In addition, above variables are reported for pools and riffles located at PRASA Intake (RÃo Mameyes) and at La Curvita (RÃo EspÃritu Santo).

Canopy Trimming Experiment (CTE) Snail data
The objective of these data is to determine how green litter deposition and canopy opening associated with a hurricane independently and jointly affect population dynamics and community composition of terrestrial gastropods. Because canopy openness can be expected to increase abiotic stress on gastropods, whereas litter deposition should provide increased resources and refugia, tradeoffs can be expected.

Plant Apparency data - Habitat selection/Caracolus caracolla and other snails (2019 Ongoing)
Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (every 0.5 m from ground level to 3 m). The files are divided because variables measured varied by year. This is Version 2020 of these data.

Habitat selection/Caracolus caracolla and other snails
Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (every 0.5 m from ground level to 3 m). The files are divided because variables measured varied by year. This data set consists of 7 files. Data sets from 1991 through 1995 each have slightly different categories for measures of litter depth, canopy openness, or physical features (e.g. slope, aspect, soil type) that are not always included in later data sets. In addition, plant species recorded changed slightly over this time period, but were standardized by 1996. Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (every 0.5 m from ground level to 3 m).

Aquatic macrophyte, snail, and crayfish abundance and richness data for ten lakes in Vilas County, WI, USA, 1987-2020
Data accompanying the paper Szydlowski et al. "Macrophyte and snail community responses to 30 years of population declines of invasive rusty crayfish (Faxonius rusticus)." Macrophytes and snails were sampled in ten lakes in Vilas County, Wisconsin, USA during summer sampling events in 1987, 2002, 2011, and 2020. Lakes had varying levels of invasion by F. rusticus, which affected measures of macrophytes and snails. Macrophytes were sampled using a point-intercept transect method and snails were sampled using different sampler types which were dependent on substrate. Macrophytes were sampled at 6-14 sites per lake and snails were sampled at 16-31 sites per lake. Crayfish were regularly sampled at either 24 or 36 sites per lake between 1987 and 2020. Overall, this dataset provides abundance and richness data for over 25 species of snails and over 40 species of macrophytes in 10 north temperate lakes.
Periwinkle snail association with cordgrass on the York River
This dataset includes tables used in a study of periwinkle snail (Littoraria irrorata) association with big cordgrass (Spartina cynosuroides) and smooth cordgrass (Spartina alterniflora) in a salt marsh along the York River. The overarching goal of this study was to assess if and how plant palatability, predation pressure, and environmental characteristics of each Spartina species influenced the densities and grazing of periwinkle snails. The data were collected in support of a study authored by Failon, Wittyngham, and Johnson in 2020 titled Ecological Associations of Littoraria irrorata with Spartina cynosuroides and Spartina alterniflora. It was published in the journal Wetlands.

HELIX: Data-driven characterization of Brazilian land snails
<p>The Subulinidae family of Brazilian land snails includes similar species with particular morphometrical characteristics. We surveyed the metro area of the Juiz de Fora/MG city and collected snails from a representative private property with centered at 21º42'31''S, 43º21'26'', alt. 795m, with red-yellow oxisol, 8.5 pH, and Cwa climate. We performed monthly collections in a ecosystem with <em>Pennisetum purpureum</em>, <em>Brachiaria mutica</em>, <em>Paspalum notatum</em>, <em>Bidens pilosa</em>, <em>Leucena leucocephala</em>, and <em>Ricinus communis</em> plants near a river flow in the 2008/Sep - 2009/Aug timespan. There, we defined an equally spaced transect of 200m with ten collection points and gathered 50 x 50 cm, 500 g litter-falls. Samples were sieved by 2.0 mm meshs, and living specimens were cleaned and fixed in a Railliet-Henry liquid, their shells removed, dried, and separated. Finally, we label the species and create the Helix dataset. We measured each shell <em>Height</em>, <em>Diameter</em>, <em>Spire height</em>, and <em>Aperture width</em> and <em>height</em> with a pachymeter. The dataset includes 518 instances labeled as <em><strong>Beckianum beckianum</strong></em> (28.8%), <em><strong>Dysopeas muibum</strong></em> (21.2%), <em><strong>Allopeas gracilis</strong></em> (9.7%), <em><strong>Leptinaria unilamellata </strong></em>(12%), and <em><strong>Subulina octona</strong></em> (28.3%). </p>
Original .tif files for "Land snails can trap trematode cercariae in their shell: encapsulation as a general response against parasites?"
<p>In our article "Land snails can trap trematode cercariae in their shell: encapsulation as a general response against parasites?", we use photographic evidence to demonstrate the ability of snails to trap trematodes in their shells. Here we archive the tif files that make up our Figure 1 for this paper, for browsing at higher resolutions than on the published article.</p> <p>Below a (slightly edited) copy of the figure legend:</p> <p>"Backlit views of metazoan parasites trapped in the shell of Cornu aspersum: trematode cercariae (Fig1A.tif, Fig1B.tif, Fig1C.tif), and nematode (Fig1D.tif). Small cracks of the inner shell layer (Fig1B.tif) can be seen above the cercariae and were considered as indicative of damage on the shell after it covered cercariae. Note the accumulation of dark adhering cells around or above the parasites in both cases of cercariae (Fig1C.tif) and nematode (Fig1D.tif)."</p>
Snail, Melampus bidentatus, length and biomass measurements for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA.
Melampus bidentatus (coffee bean snail) length and biomass measurements for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA. The TIDE project aims to simulate eutrophication on a large scale by the addition of NO3- aiming to reach 70μM concentrations from May to September every year during the growing season. This fertilization of the marsh has been going on at Sweeney Creek since the 2004 growing season through 2016 and at Clubhead Creek in 2005 and from 2009 till 2016. Invertebrates were sampled after fertilization ended to look at recovery.
Year 1999, mussel and snail surveys of tidal creeks on the Rowley River, Massacusetts.
This study was conducted during the Summer of 1999, by Governor's Academy high school science class students with their teacher Susan Olezsko-Zsuts to look at the distriibution of mussels and snails in a variety of tidal creeks off the Rowley River, Rowley and Ipswich Massachusetts.
