North Temperate Lakes LTER Bythotrephes longimanus spiny water flea population monitoring in Wisconsin and Minnesota 2009 - 2014
Three data tables are included describing population dynamics for Bythotrephes longimanus, spiny water flea, in Southern Wisconsin during invasion. General monitor took place in Lake Mendota, Lake Monona, Lake Waubesa, Lake Kegonsa, Stormy Lake, Gile Flowage, Lake Gogebic. Accompanying Bythotrephes morphological measurements from Lake Mendota monitoring efforts in 2011 and 2012. Included are individual measurements of body morphology and reproductive status for ~2,500 Bythotrephes collected from Lake Mendota in 2011 and 2012. Sediment cores from Lake Mendota were analyzed for spiny water flea evidence with age of sediment estimated.
North Temperate Lakes LTER: Trout Lake Spiny Water Flea 2014 - present
Beginning in 2014, 30 meter vertical tows with a special zooplankton net were collected in Trout Lake specifically for the invasive Bythotrephes longimanus (spiny water flea). The net has a 400 micrometer mesh with a 0.5 meter diameter opening. Individuals are simply counted, and density is determined to be the number of individuals divided by the total water volume of each tow.
Data on the fleas of house mice and ship rats in the Orongorongo Valley, New Zealand
<p>Data on autopsies and fleas of individual rats and mice snap-trapped in 80 quarterly 3-day trapping sessions over 1971-1991 in the Orongorongo Valley, Wellington, New Zealand. The fleas are preserved as slides in the Pilgrim Collection of Te Papa Tongarewa Museum of New Zealand, Wellington. The data are analysed in a forthcoming paper by Fitzgerald, Efford and Karl.</p> <p>'Autopsy data.csv' is the main spreadsheet.</p> <p>'Data format.csv' defines columns and codes.</p> <p>The autopsy data are a subset of those reported by Fitzgerald, Efford<br> and Karl (2004) and Efford, Fitzgerald, Karl and Berben (2006), both<br> with respect to the sampling period (trapping continued after May 1991,<br> but rats and mice were not searched for fleas) and data columns<br> (some reproductive fields have been omitted).</p> <p>The autopsy data may be read from the csv file into R (R Core Team 2023)<br> with the statement:</p> <p>autopsyF <- read.csv(file = 'Orongorongo fleas 1971-1991 Autopsy data.csv')</p> <p>The resulting dataframe has 31 columns and 3006 rows:</p> <p>names(autopsyF)<br> [1] "Autopsy" "Line" "Date" "Analysis.Year" "Session" <br> [6] "Day" "Season" "Trap" "Traptype" "Alive.dead" <br> [11] "Species" "Sex" "Age" "Weight" "TotLth" <br> [16] "TailLth" "Fleas" "LsegnisM" "LsegnisF" "LsegnisU" <br> [21] "Lsegnis" "NfascM" "NfascF" "NfascU" "Nfasc" <br> [26] "Vagina" "Lact" "Uterus" "EmbryosT" "ScarCond" <br> [31] "Testes" <br> <br> nrow(autopsyF)<br> [1] 3006</p> <p>For completeness, the autopsy data include 64 hosts from these trapping sessions that were<br> not searched for fleas (coded as Fleas = 2).</p> <p>Quarterly indices of host density were tabulated by Fitzgerald et al.

North Temperate Lakes LTER: Southern Lake Spiny Water Flea 2016 - present
Beginning in 2016, vertical tows with a special zooplankton net were collected in the lakes of the Yahara River specifically for the invasive Bythotrephes longimanus (spiny water flea). The net has a 400 micrometer mesh with a 0.5 meter diameter opening. Individuals are simply counted, and density is determined to be the number of individuals divided by the total water volume of each tow. The depth of the tow, and therefore the tow volume, varies by lake. Additional sampling for spiny water flea occurred 2009 - 2014 as a part of graduate student research (dataset knb-lter-ntl.343). Spiny water flea are also captured occasionally during our standard zooplankton tows of the southern lakes (knb-lter-ntl.90).
