Marine protists are integral to the structure and function of pelagic ecosystems and marine carbon cycling, with rhizarian biomass alone accounting for more than half of all mesozooplankton in the oligotrophic oceans. Yet, understanding how their environment shapes diversity within species and across taxa is limited by a paucity of observations of heritability and life history. Here, we present observations of asexual reproduction, morphologic plasticity, and ontogeny in the planktic foraminifer in laboratory culture. Our results demonstrate that planktic foraminifera reproduce both sexually and asexually and demonstrate extensive phenotypic plasticity in response to nonheritable factors. These two processes fundamentally explain …

Carbon And Nitrogen Isotope Ratios Of Chemosynthetic Biota From The Active Cold Seep Site Of, K-G Basin, Bay Of Bengal, Tanojit Paul
Manipal Institute of Technology, Manipal Theses and Dissertations
The study area in the K-G basin is a cold seep ecosystem and contains shallow methane gas hydrates (2-3 mbsf), discovered for the first time in the Indian Exclusive Economic Zone (EEZ) which is associated with methane gas flares in the water column. This methane rich gas is released into the surrounding environment which supports an extensive range of endemic organisms and plants, and it continues to be one of the most extravagant ecological system of the seabed. The methane released from the seep site reacts with the overlying seawater and over time they form carbonate rocks which is an …
Perceptions Of A Small Midwestern Food Cooperative: A Case Study, Rebecca Forsythe
Perceptions Of A Small Midwestern Food Cooperative: A Case Study, Rebecca Forsythe
Theses and Dissertations
The purpose of this research is to illuminate how individuals form perceptions of cooperatives, specifically of Green Top Grocery, a cooperative located in Bloomington Illinois, using the Bourdieu-sian habitus and notions of capital as a frame. Green Top Grocery suffers from fiscal instability since they opened in 2017. They also struggle to gain support of lower income individuals, a key demographic they sought to help since their inception based on their stated values. By conducting qualitative interviews of three sample groups: Green Top Grocery board members and leadership, local food access experts, and West Bloomington residents, and non-participant observations, this …
Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou
Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou
International Programs
A soil assessment was carried out in the savannah region of Togo in 2018, aiming at drawing the digital map of Togo’s soil fertility and making fertilizer recommendations. Soil samples were taken from geo-referenced GPS points and were analyzed for parameters such as water pH, Organic matter, available phosphorus and exchangeable potassium. Thematic maps have been drawn using an ArcGIS package. The results showed that the soils of the Savannah region in Togo are mainly (84%) not very acidic (pH = 5.5 to 6.5), overall poor to very poor (84%) in organic matter (<2% OM), essentially poor to very poor (86%) in available phosphorus (<15 mg/kg of soil) and mostly very poor (87%) in exchangeable potassium (<90 mg / kg of soil). These results allowed the agricultural research institute of Togo to make fertilizer use recommendations and to develop, in partnership with Morocco, a digital platform (fertitogo.tg ) for decision making in crop fertilization.
Analysis Of The Facilitative Interaction Between Batis Maritima And Avicennia Germinans As A Mangrove Restoration Strategy, Javier R. Navarro
Analysis Of The Facilitative Interaction Between Batis Maritima And Avicennia Germinans As A Mangrove Restoration Strategy, Javier R. Navarro
Theses and Dissertations
The multiple experiments conducted in an Avicennia germinans forest in Laguna Vista, TX was focused on determining if facilitation theory could explain the behavior observed between the herbaceous halophyte Batis maritima and A. germinans. I hypnotized that a positive interaction exists but through which mechanisms of facilitation I did not know. The overarching theme of the study is the presence or absence of B. maritima. Facilitation theory tells us that positive interactions are most often found under stressful conditions such as those on the coastal tidal flat of the Laguna Madre. Locally B. maritima has been found to …
Variability Of Selected Mineral Contents In Marine Fish From Local Markets In Tanzania, Stella Shija, Matobola Mihale, Daniel Shilla
Variability Of Selected Mineral Contents In Marine Fish From Local Markets In Tanzania, Stella Shija, Matobola Mihale, Daniel Shilla
Tanzania Journal of Science
Mineral contents (K, Na, Ca and Mg) in selected marine fish species (Alectis ciliaris, Lethrinus harak, Rastrelliger kanagurta and Siganus canaliculatus) from local fish markets were analysed in wet and dry seasons. The processing methods (frying and boiling) were also assessed for their influence on the mineral contents. Samples were randomly collected from Tanga, Bagamoyo, Dar es Salaam and Mtwara seaports, analysed using established methods and determined by Graphite Furnace Atomic Absorption Spectrometry. Mean mineral contents in individual and all analysed fish species were high during dry season compared to wet season except Ca and the difference was statistically significant …

Faculty Publications
Metal contamination of food and water resources is a known public health issue in Arctic and sub-Arctic communities due to the proximity of many communities to mining and drilling sites. In addition, permafrost thaw may release heavy metals sequestered in previously frozen soils, potentially contaminating food and water resources by increasing the concentration of metals in freshwater, plants, and wildlife. Here we assess the enrichment of selected heavy metals in Alaskan soils by synthesizing publicly available data of soil metal concentrations. We analyzed data of soil concentrations of arsenic, chromium, mercury, nickel, and lead from over 1,000 samples available through …
The Effect Of Soil Ph On Phosphorus Content Of Clover Pasture, David Weaver, Robert Summers, David Rogers, Peta Richards
The Effect Of Soil Ph On Phosphorus Content Of Clover Pasture, David Weaver, Robert Summers, David Rogers, Peta Richards
Resource management technical reports
Testing of pasture soils from 2009 to 2018, as part of DPIRD’s Whole Farm Nutrient Mapping (WFNM) project in the coastal catchments of south-west Western Australia (WA), indicated that soil pH was so low it could be limiting plant access to nutrients. Observations by some farmers who had been involved in the soil testing were that lime application had not increased pasture production, even when pHCa (pH measured in calcium chloride) tests indicated that phosphorus (P) should become more available by increasing soil pH. Farmers also wanted to know if they needed to apply more P than soil testing …
