Effects of fungal endophytes on invasive Phragmites australis (ssp. australis) performance in growth chamber and field experiments

These data tables contain data collections from field experiments of Phragmites australis (ssp. australis) treated with known fungal endophytes. Tiller counts, tiller diameter, and tiller height measurements were taken every two weeks over an eight-week study period. Clones of Phragmites plants were collected from three different locations: Sandusky, Michigan; Bloomington, Indiana; and the Ottawa National Wildlife Refuge near Oak Harbor, Ohio. Additionally, data collections from a similar experiment of Phragmites australis (ssp. australis) treated with known fungal endophytes performed in a growth chamber are included. Tiller numbers and tiller heights were measured every three weeks over 15 total weeks for the...

Effects of pulse duration on common hydroacoustic measures in Lake Erie in 2011-2012 and Ohio Reservoirs in 2017

Hydroacoustics is a common sampling tool in freshwater and marine ecosystems, yet the full potential of this tool remains restricted, owing to an incomplete understanding of the influence of many data collection settings. In particular, investigation into the effects of the pulse duration setting on common hydroacoustic measures remains limited. Hydroacoustic theory suggests that pulse duration can affect how many single targets (e.g., individual fish or invertebrates) are detected, the mean target strength (TS) of sample cells, and estimates of target density, especially in ecosystems with an abundance of potential targets. To quantify the influence of the pulse duration setting on these important and commonly...

Microsatellite genotypes for Lake Sturgeon (Acipenser fulvescens) Eggs and Larvae from Constructed Reefs in the St. Clair-Detroit River System (2015-2016)

This dataset contains the physical collection information (e.g., sample location, date, gear type) and microsatellite DNA genotype of egg and larval Lake Sturgeon collected in the St. Clair and Detroit rivers in 2015 and 2016. Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

Invasive carp movement rates among five herding techniques using adaptive resolution imaging sonar on the Lower Perche Creek, Columbia, MO

Data represent a comparison of herding techniques commonly used by natural resource agencies and the public to increase removal or harvest of invasive carp (i.e., Silver Carp) from U.S. waterways. Sites on lower Perche Creek, Columbia, MO (2018 August 9th to 2018 October 26th) were contained using block nets and treated with one of five herding techniques: (1) method commonly used by commercial fishers in the U.S. (“commercial technique”), (2) pulsed-DC electrofishing (“electric technique”), (3) broadband sound administered with underwater speakers (“sound technique”), (4) both sound and electric in combination (“combination technique”), and (5) solely the boat with no added stimulus (“control”). Sites were administered...

Cytonuclear discordance in the Florida Everglades invasive Burmese python (Python bivittatus) population reveals possible hybridization with the Indian python (P. molurus)

Invasive Burmese pythons (Python bivittatus) have been reproducing in the Florida Everglades since the 1980s. Introduction of the species was either due to unintentional escapes or intentional releases from snakes obtained through the commercial pet trade. Burmese pythons have caused a precipitous decline in small mammal populations in south Florida. To better understand the invasive population, two mitochondrial loci (mtDNA; 1398 bps) were sequenced on 426 snakes and 22 microsatellites were genotyped on 389 snakes. Concatenated cytochrome b and cytochrome oxidase 1 mtDNA sequences produced six haplotypes with a nucleotide and haplotype diversity of π=0.002 and h=0.097, respectively. The dominant haplotype was highly...

Brazoria NWR Prairie Resilience Data

In 1996, 400 tree-centered plots were established by first randomly choosing x- and y- coordinates from an imaginary grid overlaying the study area. Each random point was also randomly assigned a tree-size category from a pre-determined sampling scheme. The scheme was to include 20 trees from each of 5 size categories. Size/height categories were: less than 0.1m, 0.1-1m, 1-2m, 2-3m, and greater than 3.0m. To avoid excessive aggregation of samples, no more than 5 trees in a size class could be chosen within a 100-meter sub-area of the sampling grid. The nearest tree to each random point that met the pre-determined size requirement was identified and marked with a permanent aluminum tag. For the size category less...
