Degraded Environments Alter Prey Risk Assessment

Degraded Environments Alter Prey Risk Assessment

Elevated water temperatures, a decrease in ocean pH, and an increasing prevalence of severe storms have lead to bleaching and death of the hard corals that underpin coral reef ecosystems. As coral cover declines, fish diversity and abundance declines. How degradation of coral reefs affects behavior of reef inhabitants is unknown. Here, we demonstrate that risk assessment behaviors of prey are s...

Scratch Resistance of Paints Degraded by Arid Saharan Environments

In the vast Algerian Sahara, the climate is typically desert, characterized by heat and dryness all year, which contributes to a very pronounced aridity. The aim of this study is to investigate the impact of this arid environment on automotive paints. Four paint samples with different durations of use were tested. Initially, a visualization of the surface condition by optical microscopy and...

Assessment of Critical Condition for Rill Initiation on Degraded Hillslope

Generally, the evaluation and assessment critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hill-slopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision thre...

Trait-Mediated Effects in Rocky Intertidal Food Chains: Predator Risk Cues Alter Prey Feeding Rates

The influence of predation on rocky intertidal community structure has long emphasized the importance of indirect interactions. Most efforts in this area have focused on the density-mediated, or lethal effects, of predators on prey density. Recently, there has been growing interest in trait-mediated indirect interactions (TMIIs): the presence of a predator in the environment influences the inte...
