Animals are considered to possess personalities when individuals differ in behavior, and these differences are consistent between situations. Several studies have identified personalities in diverse groups but less is known about personality variation between the sexes. In this study, we examined variation in two key personality traits (boldness, activity) in female and male purple marsh crabs (Sesarma reticulatum) using a semi-field approach. Specifically, we measured boldness and activity on two consecutive days using the same behavioral assays during each time point. Consistency (personality) was determined using Kendall’s coefficient of concordance based on Spearman correlation coefficients for each behavior. …
Effects Of Reduced Ph On Health Biomarkers Of The Seagrass Cymodocea Nodosa, Regan A. Mcenaney
Effects Of Reduced Ph On Health Biomarkers Of The Seagrass Cymodocea Nodosa, Regan A. Mcenaney

Ocean acidification is a growing problem that may affect many marine organisms in the future. Within 100 years the pH of the ocean is predicted to decrease to 7.8, from the current ocean pH of around 8.1. Using phenolic acid levels as a stress indicator as well as respiration and chlorophyll content as a measure of health, the effect of lowering pH was tested on the seagrass, Cymodocea nodosa, in a controlled environment. Plant samples, water, and soil were taken from the Bay of Cádiz, Spain, and placed in aquaria in a temperature-controlled room. One control group was left …

The Intrinsic Value Of Nature, Joanna E. Lambert
Animal Sentience
Treves et al. explain the need to preserve the rights of nonhuman species, human youth, and future generations. Although conservation biology has claimed to have an intrinsic valuation ethic since its inception in the 1980s, many aspects of the field have taken a decidedly anthropocentric and instrumentalist trajectory. This has important consequences for conservation-related policy and practice at all scales: local, regional, and global.
The Diversity Of Terrestrial Mammals Surrounding Waterfall At Billy Barquedier National Park, Kelsey Johnson, Jason Apple
The Diversity Of Terrestrial Mammals Surrounding Waterfall At Billy Barquedier National Park, Kelsey Johnson, Jason Apple
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Billy Barquedier is a National Park located in the Stann Creek district of Belize that contains Neotropical vegetation and wildlife. This study was performed to provide a baseline inventory and appearance frequency patterns of the terrestrial mammals located within Zone 1 of the park near a waterfall and to gain a greater understanding of the biodiversity and activity patterns of terrestrial mammals within the park. The methods included camera traps, small Sherman live traps, large live traps, and tracking methods. A non-random sampling method of placing camera traps and live traps on or near human-made or animal-made trails was used …
