These data are collected to document and characterize the submersed macrophytes of Trout Lake and to evaluate their long-term dynamics and interactions with other compartments of the ecosystem. Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. This dataset includes biomass per m2 for individual species at three depths along the transect. These data are useful in determining the annual variability of the submersed macrophytes and providing information on the effects of the invasion of an introduced crayfish Sampling Frequency: annually during summer Number of sites: 4

North Temperate Lakes LTER: Macrophyte Transects - Trout Lake 1982 - current
These data are collected to document and characterize the submersed macrophytes of Trout Lake to evaluate the long-term stability of this component and to interface with investigations of other compartments of the ecosystem. Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. This dataset includes species presence/absence and transect summary data by depth along the transect. This information is useful in determining the annual variability of the submersed macrophytes and providing information on the effects of the invasion of an introduced crayfish Sampling Frequency: annually during summer Number of sites: 4

These data are collected to document and characterize the submersed macrophytes of Trout Lake, to evaluate the long-term stability of this component, and to interface with investigations of other compartments of the ecosystem. Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. This dataset includes biomass per m2 for individual species summarized by depth along the transect. Derived data include the mean and standard deviation of macrophyte biomass. These data are useful in determining the annual variability of the submersed macrophytes and providing information on the effects of the invasion of an introduced crayfish.

These data are collected to document and characterize the submersed macrophytes of Trout Lake, to evaluate the long-term stability of this component, and to interface with investigations of other compartments of the ecosystem. Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. These are quadrat-species level data. This dataset only contains information on species that were present. It includes a row for every species-quadrat present. If a quadrat is missing, that quadrat was either empty or was not sampled.

Four sites along the shoreline of Trout Lake have been sampled annually in August along permanent line transects. These data are quadrat level data. This dataset includes a row for every quadrat sampled. The RICHNESS field contains the number of species present (set to zero if the quadrat was empty).

{"Abstract":["Data accompanying the paper Szydlowski et al. "Macrophyte and snail community responses\n to 30 years of population declines of invasive rusty crayfish (Faxonius rusticus)."\n Macrophytes and snails were sampled in ten lakes in Vilas County, Wisconsin, USA during\n summer sampling events in 1987, 2002, 2011, and 2020. Lakes had varying levels of invasion\n by F. rusticus, which affected measures of macrophytes and snails. Macrophytes were sampled\n using a point-intercept transect method and snails were sampled using different sampler\n types which were dependent on substrate. Macrophytes were sampled at 6-14 sites per lake and\n snails were sampled at 16-31 sites per lake. Crayfish were regularly sampled at either 24 or\n 36 sites per lake between 1987 and 2020. Overall, this dataset provides abundance and\n richness data for over 25 species of snails and over 40 species of macrophytes in 10 north\n temperate lakes."]}more » « less
