Title Effect of coastal urbanization on sandy beach coleoptera Phaleria maculata (Kulzer, 1959) in northern Chile Type Journal Article
Year 2014 Publication Marine Pollution Bulletin Abbreviated Journal Mar Pollut Bull
Volume 83 Issue 1 Pages 265-274
Keywords Anthropogenic impact; Coastal urbanization index; Light pollution; Marine tenebrionid; Phaleria maculata; beetles; insects; urbanization; Chile; morphodynamics; Urbanization Index; indicator organisms
Abstract The beetle Phaleria maculata is a common inhabitant of the upper intertidal fringe of Chilean beaches. Anthropogenic intervention in coastal areas has increased intensely, leading to changes in the flora and fauna of sandy beaches. To examine the impact of human activities on P. maculata, we studied several beaches along the northern Chilean coast. Beaches were characterized based on morphodynamics and the level of intervention, leading to the estimation of an “Urbanization Index” based on various indicators. The analysis showed a significant inverse correlation between the rate of urbanization and night sky quality. Larval and adult beetles were almost absent on beaches with high levels of urbanization. The results of simple and multiple correlations based on nMDS ordination showed an inverse relationship between increases in urbanization and the abundance of beetles. Because darkling beetles are very sensitive to human interventions on sandy beaches, we suggest that they are ideal indicator organisms for the health of these environments.

Title Effects of light pollution on the emergent fauna of shallow marine ecosystems: Amphipods as a case study Type Journal Article
Year 2015 Publication Marine Pollution Bulletin Abbreviated Journal Marine Poll. Bull.
Volume 94 Issue 1-2 Pages 235–240
Keywords Animals; Light pollution; Emergent fauna; Amphipoda; Coastal management; Great Barrier Reef; Australia; LED; halogen
Abstract Light pollution from coastal urban development is a widespread and increasing threat to biodiversity. Many amphipod species migrate between the benthos and the pelagic environment and light seems is a main ecological factor which regulates migration. We explore the effect of artificial lighting on amphipod assemblages using two kind of lights, LED and halogen, and control traps in shallow waters of the Great Barrier Reef. Both types of artificial light traps showed a significantly higher abundance of individuals for all species in comparison to control traps. LED lights showed a stronger effect over the amphipod assemblages, with these traps collecting a higher number of individuals and differing species composition, with some species showing a specific attraction to LED light. As emergent amphipods are a key ecological group in the shallow water environment, the impact of artificial light can affect the broader functioning of the ecosystem.
