Growth and survival of Clostridium botulinum type E in pasteurized oysters
… C; D-values ranged from 65 to 100 min at 700 C and 880 to 1300 min at 550 C. When tubes of oyster homogenate were inoculated with 1x103 type E spores/ml and stored at 3, 6, 12, and 30oC, no growth was observed; however, when the inocculum was increased to 1x104 spores/ml, toxin was produced …

Growth and Survival of Largemouth Bass in Newly Stocked South Dakota Impoundments
… effect of five different stocking combinations and differences in climatic and morphological conditions within South Dakota on initial growth and survival of the largemouth bass (Micropertus salmoides). Forage species stocked with bass included gold shiners (Notemigonus crysoleucas), fathead …

Modeling Size Dependent Interactions of a Juvenile Piscivore: Implications for Growth and Survival
… of size-specific interactions on foraging and mortality has consequences for growth and recruitment of juvenile fish. Many juvenile piscivores, such as walleye (Stizostedion vitreum), undergo ontogenetic diet shifts switching from zooplanktivory to benthivory and, finally, piscivory. These …

First Year Growth and Survival of Walleyes in Power Plant Evaporation and Holding Reservoirs
… in two South Dakota power plant reservoirs and their growth and survival were monitored for one year. Length, weight, and survival of walleyes were significantly (P < 0.05) different between the two reservoirs. The walleyes attained a mean length of 230 mm (range 192 - 265 mm) in the …

Restoring the Chocó: Growth and Survival of Native Chocoan Trees Using Different Propagation Methods
… one of the most biodiverse places on the planet and has been identified as a priority area for conservation due to its high levels of endemism and diversity, currently threatened by the ongoing loss of forest cover. In this context, establishing baseline data on the survival and growth rates of …

The Endoplasmic Reticulum Udpase ENTPD5 Promotes Cancer Cell Growth and Survival in the PI3K/PTEN
PI3 Kinase and PTEN lipid phosphatase control the level of cellular phosphatidylinositol (3,4,5)-trisphosphate, an activator of AKT kinase that promotes cell growth and survival. Mutations activating AKT are commonly observed in human cancers. Activation of AKT and downstream PI3 Kinase signaling …

Delineating the Mechanisms Through Which ZNF165 Supports Growth and Survival of Triple-Negative Breast Cancer
… was previously identified as essential for the growth and survival of TNBC and sustained transforming growth factor beta (TGFβ) signaling. However, the mechanisms through which ZNF165 functions in this context to regulate both TGFβ signaling and survival were poorly understood. To investigate …

Determinants of Growth and Survival of Larval Pallid Sturgeon: A Combined Laboratory and Field Approach
… to exogenous feeding in pallid sturgeon and quantified prey taxa-specific growth and survival for zooplankton and Chironomidae and Ephemeroptera larvae in discrete pallid sturgeon size classes (first feeding larvae, 20 to 30 mm, 30 to 40 mm). We quantified pallid sturgeon prey selection …

First-year growth and survival of habitat revegetation trials on the lower Colorado River, Mexico
… A brief return of freshwater flows in the 1980s and 1990s showed the riparian corridor remains resilient to past damage, and the CRD remains a vital area for habitat conservation and restoration. This project aimed to test conclusions drawn from similar projects in the United States and show that …

Investigation into three potential modifying factors in larval fathead minnow (Pimephales promelas) growth and survival
… toxicity tests may be modified by events and stressors not associated with the toxicants themselves. In the following work, three potential modifying factors related to larval fish growth, survival, and response to toxicant stress were investigated. Using four-day acute cadmium toxicity …

Fine-Scale Mechanisms Influencing Germination Success, Seedling Growth and Survival in an Alpine Forest-Tundra Ecotone
… seed production, germination, establishment and growth of young seedlings. To that end, I studied the white spruce (Picea glauca) alpine treeline in the Kluane region of southwest Yukon to explore two important questions related to treeline ecology: (1) Is there sufficient viable seed …

Initial Growth and Survival of Bluegills and Black Bullheads Stocked With Largemouth Bass in South Dakota Ponds
Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in …
