Title NightLife: A cheap, robust, LED based light trap for collecting aquatic insects in remote areas Type Journal Article
Year 2016 Publication Biodiversity Data Journal Abbreviated Journal Bdj
Volume (up) 4 Issue Pages e7648
Keywords Animals; Ecology; Lighting
Abstract Background

There are approximately one hundred thousand aquatic insect species currently known to science and this figure is likely a significant underestimation. The ecology of aquatic insect groups has been studied due to their role as bioindicators of water quality and in the case of Diptera, their role as vectors of disease. Light trapping targets emergent adults, using mercury vapour bulbs or actinic fluorescent tubes, however these light sources are unsuitable for sampling remote regions due to their power requirements, which limit their mobility. Most insects studied have three types of photoreceptors corresponding to UV, blue and green light.

New information

We describe the NightLife: a cheap, robust, portable, LED based light source which targets insect trichromatic vision, is capable of autonomous operation and is powered by a single AA battery. Field trials show that the NightLife is capable of collecting sufficient samples of 12 insect orders, including all aquatic orders commonly collected by traditional light trapping and compares favourably with actinic fluorescent tubes and white LEDs. Future development in LED technology will likely result in LEDs replacing traditional light sources for collecting insects more widely.

Title Method to improve the survival of night-swarming mayflies near bridges in areas of distracting light pollution Type Journal Article
Year 2017 Publication Royal Society Open Science Abbreviated Journal R. Soc. open sci.
Volume (up) 4 Issue 11 Pages 171166
Keywords Animals; Lighting
Abstract Numerous negative ecological effects of urban lighting have been identified during the last decades. In spite of the development of lighting technologies, the detrimental effect of this form of light pollution has not declined. Several insect species are affected including the night-swarming mayfly Ephoron virgo: when encountering bridges during their mass swarming, these mayflies often fall victim to artificial lighting. We show a simple method for the conservation of these mayflies exploiting their positive phototaxis. With downstream-facing light-emitting diode beacon lights above two tributaries of the river Danube, we managed to guide egg-laying females to the water and prevent them from perishing outside the river near urban lights. By means of measuring the mayfly outflow from the river as a function of time and the on/off state of the beacons, we showed that the number of mayflies exiting the river's area was practically zero when our beacons were operating. Tributaries could be the sources of mayfly recolonization in case of water quality degradation of large rivers. The protection of mayfly populations in small rivers and safeguarding their aggregation and oviposition sites is therefore important.

Title Filtered Streetlights Attract Hatchling Marine Turtles Type Journal Article
Year 2006 Publication Chelonian Conservation and Biology Abbreviated Journal Chelonian Conservation and Biology
Volume (up) 5 Issue 2 Pages 255-261
Keywords Reptilia; Testudines; Cheloniidae; Loggerhead turtle; turtles; marine turtles; reptiles; Caretta caretta; Chelonia mydas; hatchlings; artificial lighting; light “trapping”; orientation; seafinding; Florida
Abstract On many nesting beaches, hatchling marine turtles are exposed to poled street lighting that disrupts their ability to crawl to the sea. Experiments were done to determine how hatchlings responded to street lighting transmitted through 2 filters that excluded the most disruptive wavelengths (those <&#8201;530 nm; those <&#8201;570 nm). Filtered lighting, however, also attracted the turtles though not as strongly as an unfiltered (high-pressure sodium vapor) lighting. Filtering is therefore of limited utility for light management, especially since other alternatives (such as lowering, shielding, or turning off unnecessary lighting; use of dimmer lights embedded in roadways) are more effective.
