Title Avian mortality at communication towers in the United States and Canada: which species, how many, and where? Type Journal Article
Year 2013 Publication Biological Conservation Abbreviated Journal Biological Conservation
Volume 158 Issue Pages 410-419
Keywords
Abstract Birds migrating to and from breeding grounds in the United States and Canada are killed by the millions in collisions with lighted towers and their guy wires. Avian mortality at towers is highly variable across species, and the importance to each population depends on its size and trajectory. Building on our previous estimate of avian mortality at communication towers, we calculated mortality by species and by regions. To do this, we constructed a database of mortality by species at towers from available records and calculated the mean proportion of each species killed at towers within aggregated Bird Conservation Regions. These proportions were combined with mortality estimates that we previously calculated for those regions. We then compared our estimated bird mortality rates to the estimated populations of these species in the United States and Canada. Neotropical migrants suffer the greatest mortality; 97.4% of birds killed are passerines, mostly warblers (Parulidae, 58.4%), vireos (Vireonidae, 13.4%), thrushes (Turdidae, 7.7%), and sparrows (Emberizidae, 5.8%). Thirteen birds of conservation concern in the United States or Canada suffer annual mortality of 1–9% of their estimated total population. Of these, estimated annual mortality is >2% for Yellow Rail (Coturnicops noveboracensis), Swainson’s Warbler (Limnothlypis swainsonii), Pied-billed Grebe (Podilymbus podiceps), Bay-breasted Warbler (Setophaga castanea), Golden-winged Warbler (Vermivora chrysoptera), Worm-eating Warbler (Helmitheros vermivorum), Prairie Warbler (Setophaga discolor), and Ovenbird (Seiurus aurocapilla). Avian mortality from anthropogenic sources is almost always reported in the aggregate (“number of birds killed”), which cannot detect the species-level effects necessary to make conservation assessments. Our approach to per species estimates could be undertaken for other sources of chronic anthropogenic mortality.

Title Higher Catch Rates Around the Full Moon for Blue Marlin, Makaira Nigricans, in a Diurnal Trolling Fishery Type Journal Article
Year 2013 Publication Bulletin of Marine Science Abbreviated Journal Bms
Volume 89 Issue 3 Pages 759-765
Keywords fish; blue marlin; Makaira nigricans; Moon; moonlight; Feeding Behavior
Abstract The relationship between lunar phase and catch rates of blue marlin, Makaira nigricans Lacépède, 1802, in a diurnal trolling fishery at Yonaguni Island, southwestern Japan, was investigated. The mean catch per unit effort of blue marlin to lunar day was expressed by a periodic regression and significantly increased around the full moon. The stomach content index also significantly increased around the full moon in small blue marlin (<200 cm lower jaw–fork length), indicating that diurnal feeding activities of blue marlin increased around the full moon, especially for smaller individuals. The diurnal feeding activity is thought to be influenced by the nighttime activities of blue marlin and/or prey movements.

Title Potential effects of artificial light associated with anthropogenic infrastructure on the abundance and foraging behaviour of estuary-associated fishes Type Journal Article
Year 2013 Publication Journal of Applied Ecology Abbreviated Journal J Appl Ecol
Volume 50 Issue 1 Pages 43-50
Keywords fish; biology; ecology
Abstract As a consequence of a positive phototaxic response, the findings of this study suggest that artificial light often associated with man-made structures has the potential to alter fish communities within urban estuarine ecosystems by creating optimal conditions for predators. Future coastal developments should consider the ecological implications of lighting on aquatic communities. We recommend that lighting be minimized around coastal infrastructure and the use of red lights, which have limited penetration though water, be considered.

Title Better in the dark: two Mediterranean amphibians synchronize reproduction with moonlit nights Type Journal Article
Year 2013 Publication Web Ecology Abbreviated Journal Web Ecol.
Volume 13 Issue 1 Pages 1-11
Keywords animals; amphibians; Hyla intermedia; Rana dalmatina; *Reproduction; reproductive strategies; Moon; moon phase; moonlight
Abstract In Amphibians, both positive and negative correlations between activity and full moon phase have been observed. In this study, we present data for two anuran species (Hyla intermedia and Rana dalmatina) studied in a hilly Mediterranean area of central Italy. We analysed, in a two-year survey, the relationships between the number of egg clutches laid each night and the moon phases by means of circular statistics. Moreover, the studied species exhibited clear oviposition site selection behaviour influenced, at least in H. intermedia, by moon phases. We observed the occurrence of an avoidance effect by amphibians for oviposition and specific egg-laying behaviour during moon phases around the full moon. This apparent lunar phobia was evident in both species when yearly data were pooled. On the other hand, while this pattern continued to be also evident in H. intermedia when single years were considered, in R. dalmatina it stood just in one year of study. Nonetheless, during cloudy nights, when moonlight arriving on the ground was low, the frogs' behaviour was similar to that observed in new moon phases. We interpreted the observed pattern as an anti-predatory strategy. Overall, comparisons between our own study and previous research suggest that there was insufficient evidence to establish any unequivocal patterns and that further research in this regard is needed.

Title Amphibians' response to the lunar synodic cycle--a review of current knowledge, recommendations, and implications for conservation Type Journal Article
Year 2013 Publication Behavioral Ecology Abbreviated Journal Behavioral Ecology
Volume 24 Issue 1 Pages 53-62
Keywords amphibians; circular statistics; light; lunar cycle; moon phase; predator avoidance; reproductive synchronization; moonlight
Abstract The way in which amphibians respond to the geophysical changes brought about by the lunar synodic cycle is a neglected area of their ecology, but one which has recently generated interest. Knowledge of how amphibians respond to lunar phase is of intrinsic interest and also may be important for conservation and monitoring of populations. We surveyed the literature on amphibians’ responses to the lunar cycle and found 79 examples where moon phase in relation to amphibian behavior and ecology had been studied, across diverse amphibian taxa. Of the examples reviewed, most of them show some type of response to lunar phase, with only a few species being unaffected. We found that there is no significant difference between the numbers of species which increase, and those that decrease activity or reproductive behavior (including calling) during a full moon. The responses to the lunar cycle can not be generalized across taxonomic group, but instead are highly species specific and relate directly to the species’ ecology. The primary reasons for changes in amphibian behavior in response to the lunar cycle appear to be temporal synchronization of breeding and predator avoidance. Responses to changes in prey availability, facilitation of visual signalling and use of lunar cues in navigation and homing are less prevalent but merit further investigation. Comparisons between studies are hampered by differences in field and analytical methods; we therefore make a number of recommendations for future collection and analysis of data related to lunar phase.
