Soil Chemistry And Enzyme Data Examining Impacts Of Callery Pear Stem Cutting, Michaela J. Woods, Grace K. Attea, Ryan W. Mcewan

Five Rivers MetroParks Collaboration Data Archive

This dataset encompasses information following the collection of soil from underneath cut and treated Callery pear stems and untreated Callery pear trees. Soil was assessed for moisture, pH, and enzyme activities.

Plant root distributions are thought to determine plant growth and coexistence, but are notoriously difficult to measure. This dataset describes the concentration of deuterium oxide in plant tissues in plots where deuterium oxide was injected to target depths.

Dataset For "Attributes Of Phragmites Australis In Response To Climate Change Using A Common Garden Study", Stephen L. Young

Browse all Datasets

The response of plant species to environmental change, including climate, is based on phenotypic plasticity. Empirical research can help in understanding how invasive plants adapt to changing conditions for successful establishment. Our goal was to assess the effect of environment of origin and ecotypic variation on phenotypic response of native and invasive Phragmites australis using morphological and ecophysiological measurements. We established a common garden study using seeds collected from Southwest, Midwest, and Great Lakes regions that crossed longitudinal and latitudinal gradients of the US. Within and end of growing season measurements were made for morphological (e.g., height, leaf size, inflorescence) …

Seed Size And Germination, Meredith Cobb, Michaela J. Woods, Ryan W. Mcewan

Five Rivers MetroParks Collaboration Data Archive

This dataset encompasses information related to predictors of seed germination from the species Carya laciniosa, Juglans cinerea, and Quercus rubra. Seed sizes were recorded prior to incubation in sand, vermiculite, or without media. Seeds were then germinated with time to germination recorded in this dataset.

Non-Native Microstegium Vimineum Populations Collapse With Fungal Leaf Spot Disease Outbreak, Robert Warren

Biology Faculty Datasets

Abstract

Non-native plants may meet little resistance in the novel range if they leave their biological enemies at home. As a result, species invasion can be rapid and appear unlimited. However, with time, organisms may acquire novel enemies in the novel range, or home-range enemies also may colonize the novel range. For plants, several authors have suggested that enemy release may give way to enemy acquisition in which pathogens accumulate and suppresses non-native plants. The ‘naturalization’ that occurs with acquired enemies may take decades to develop, yet most species invasion research lasts less than 4 years, and data tracking plant …

Comparing Water Quality For Aquaponics Systems With Different Solids Removal Methods And Biofilter Media, And Effluent Output To Grow Beds, John W. Cutt, Heather M. Joesting, Brigette A. Brinton

Honors College Theses

Aquaponics is a closed-loop, sustainable method of food production that combines fish and plant production. This method of agriculture has the potential to bring fresh, local food to food-insecure areas, but challenges remain due to high operating costs. In order to develop a strong aquaponics industry, the creation of the most efficient system designs will be critical in optimizing production. This study’s purpose was to compare water quality between two aquaponics system designs that differ in filtration and solid removal methods. System 1 used a sock filter for solid removal and Kaldnes media for biofiltration while System 2 used a …

Floral Display And Habitat Fragmentation: Effects On The Reproductive Success Of The Threatened Mass-Flowering Conospermum Undulatum (Proteaceae) [Dataset], Nicola Delnevo, Eddie Van Etten, Margaret Byrne, William Stock

Research Datasets

1. Fragmentation of natural vegetation is currently one of the largest threats to plant populations and their interactions with pollinators. Plant reproductive susceptibility to habitat fragmentation has been investigated in many species; however, the response of wild mass-flowering species is poorly known, with research limited to mainly boreal plant species.

2. Here we studied twelve remnant populations of the threatened mass-flowering shrub Conospermum undulatum in the southwest Australian biodiversity hotspot, each presenting different population size, level of isolation, and floral display. We assessed the impact of fragmentation on: 1) fruit and seed production; and 2) seed germination. To gain a …
