Both Environmental Conditions and Intra- and Interspecific Interactions Influence the Movements of a Marine Predator.

Animal movements are typically influenced by multiple environmental factors simultaneously, and individuals vary in their response to this environmental heterogeneity. Therefore, understanding how environmental aspects, including biotic, abiotic, and anthropogenic factors, influence the movements of wild animals is an important focus of wildlife research and conservation. We apply Exponential Random Graph Models (ERGMs) to analyze movement networks of a bull shark population in a network of acoustic receivers and identify the effects of environmental, social, or other types of covariates on their movements.

Effects of Small and Normalized Q-Factor Changes and Knee Alignment on Knee Biomechanics during Stationary Cycling.

Increasing inter-pedal distance (Q-Factor: QF) in cycling increases peak internal knee abduction moments (KAbM). The effect of smaller and normalized changes in QF has not been investigated. The purposes of this study were to examine changes in KAbM with small and normalized increases and whether static knee alignment accounts for any changes in knee biomechanics in cycling.

Is Support in the Anxiety of the Beholder? How Anxiety Interacts with Perceptions of Instructor Support in Introductory Biology Classes.

High levels of student anxiety are negatively related to degree persistence, academic achievement, and student perceptions of instructor support. Anxiety levels vary along many axes-among classes, within students in the same class, and over time-creating a dynamic emotional landscape in classrooms. In this study, we examined the relationship between student anxiety levels and perceptions of instructor support within three introductory biology classes at two timepoints during a semester.

A randomized pretest-posttest control group study investigated the effects of 8-week strategy instruction in one of four treatment conditions on WPS accuracy of third graders with MD ( = 136) when compared to children with ( = 28) and without MD ( = 43). Comparisons were made of three strategy conditions that included overt cues (e.

Assessing mechanisms for microbial taxa and community dynamics using process models.

Disentangling the assembly mechanisms controlling community composition, structure, distribution, functions, and dynamics is a central issue in ecology. Although various approaches have been proposed to examine community assembly mechanisms, quantitative characterization is challenging, particularly in microbial ecology. Here, we present a novel approach for quantitatively delineating community assembly mechanisms by combining the consumer-resource model with a neutral model in stochastic differential equations.

Sustained bacterial NO reduction at acidic pH.

Nitrous oxide (NO) is a climate-active gas with emissions predicted to increase due to agricultural intensification. Microbial reduction of NO to dinitrogen (N) is the major consumption process but microbial NO reduction under acidic conditions is considered negligible, albeit strongly acidic soils harbor nosZ genes encoding NO reductase. Here, we study a co-culture derived from acidic tropical forest soil that reduces NO at pH 4.

First report of root rot of strawberry caused by , a member of the species complex, in Tennessee, USA.

Strawberry (Fragaria × ananassa Duch) in Tennessee is cultivated on plastic mulched beds annually, and production is limited primarily by multiple oomycete and fungal root rot pathogens that result in reduced vigor and black root rot disease symptoms. In early June 2018, plants (cv. Chandler) with reduced shoot vigor and size, and black, necrotic stunted roots were collected from Rhea County, TN.

Dose Measurements at Provision Proton Therapy Center.

Proton therapy is an advanced method for treating cancerous tumors, and its adoption has expanded significantly in recent years. The production of high-energy protons, however, may result in the creation of secondary neutrons and gamma rays. Hence, ensuring radiation safety at proton therapy centers is crucial, with shielding playing a vital role.

Boosting Dimethyl Carbonate Production from CO and Methanol using Ceria-Ionic Liquid Catalyst.

As a crucial strategy towards a sustainable chemical industry, the direct synthesis of dimethyl carbonate (DMC) from renewable carbon dioxide (CO) and methanol (MeOH) is studied using CeO nanoparticles modified with 1-butyl-3-methylimidazolium hydrogen carbonate ([BMIm][HCO]) devoid of stoichiometric dehydrating agents. The synthesized CeO@[BMIm][HCO] catalyst having high thermal stability harnesses the unique physicochemical properties of CeO and the ionic liquid to exhibit a DMC yield of 10.4 % and a methanol conversion of 16.

Living in an Intimate Partner Violence Shelter During a Pandemic: Perspectives from Advocates and Survivors.

Purpose: With state-wide quarantine policies during the COVID-19 pandemic like those implemented in the state of Texas, intimate partner violence (IPV) shelter staff were forced to incorporate new safety measures to keep survivors and advocates safe. To understand the impact of these adaptations fully, authors interviewed shelter staff and residents to capture both of their experiences living and working in the same shelter during the height of the coronavirus pandemic (summer 2020) to understand how changes in policy and procedure in shelters impacted survivors and advocates.

Materials And Methods: A qualitative phenomenological design was utilized to collect and analyze data from 10 staff and 10 survivors to develop both a textual and a structural description of participant experiences living in an IPV shelter.

A phosphorylation-deficient ribosomal protein eS6 is largely functional in , rescuing mutant defects from global translation and gene expression to photosynthesis and growth.

The eukaryote-specific ribosomal protein of the small subunit eS6 is phosphorylated through the target of rapamycin (TOR) kinase pathway. Although this phosphorylation event responds dynamically to environmental conditions and has been studied for over 50 years, its biochemical and physiological significance remains controversial and poorly understood. Here, we report data from , which indicate that plants expressing only a phospho-deficient isoform of eS6 grow essentially normally under laboratory conditions.
