Analysis Of Ecological Tradeoffs Between Congeneric Shrimp In Coastal Mississippi Waters, Baylor K. Lynch

Honors Theses

Palaemonidae is an ecologically important and abundant family of shrimp that link the benthos to many estuarine food webs. Palaemon pugio and Palaemon vulgaris regularly co-occur along estuarine edge habitats despite previous studies suggesting different preferred sediment types and salinity regimes. The objective was to determine if competition is occurring between the congeners by comparing their relative abundance and assessing isotope niche space along an estuarine gradient. I seasonally sampled various edge habitats at four sites throughout Biloxi Bay, MS, using fyke nets fished over a tidal cycle from November 2020 to November 2021. Collected organisms were identified to the …

Exergaming In A Multiplayer And Inter-Team Competition Mode With Play Lü: Effects On Adolescents’ Moderate-To-Vigorous Physical Activity And Situational Interest, Cédric Roure, Patrick Fargier, Guillaume Girod, Valérian Cécé, Denis Pasco, Vanessa Lentillon-Kaestner

International Journal of Physical Activity and Health

Objective: The goal of this study was to evaluate the impact of a Play Lü inter-team competition exergame on adolescents’ moderate-to-vigorous physical activity (MVPA) and situational interest (SI).

Materials and Methods: A total of 110 students (M_age = 13.7 ± 1.1, 12-16 years, 53.7 % girls, M_BMI = 19.9 ± 3.2) from a secondary school located in Switzerland participated to the study. They played three separate 20-min games in a counterbalance allocated order: (1) Play Lü multiplayer and inter-team competition exergame; (2) Play Lü single-player competition exergame; and (3) Tic-Tac-Toe multiplayer and inter-team competition game. …

Lianas Significantly Reduce Aboveground And Belowground Carbon Storage: A Virtual Removal Experiment, Sergio Estrada-Villegas, Sara Sofia Pedraza Navaez, Adriana Sanchez, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

Lianas are a quintessential tropical plant growth-form; they are speciose and abundant in tropical forests worldwide. Lianas compete intensely with trees, reducing nearly all aspects of tree performance. However, the negative effects of lianas on trees have never been combined and quantified for multiple tropical forests. Here, we present the first comprehensive standardized quantification of the effect of lianas on trees across tropical forests worldwide. We used data from 50 liana removal experiments and quantified the effect size of lianas on tree growth, biomass accretion, reproduction, mortality, leaf water potential, sap flow velocity, and leaf area index (LAI) across different …
