Table 1. Summary of successful applications of sensory ecology in conservation and wildlife management.
Sensory modality | Taxa | Species | Conservation issue solved | Overview | Reference |
---|---|---|---|---|---|
Vision | Bird | Canada geese (Branta canadensis Linnaeus) | Reduce airstrikes | Development of artificial lights to minimize collisions with aircraft | Blackwell et al., 2012 |
Fairy terns (Sterna nereis davisae) | Relocation | Visual decoys attracted endangered fairy terns to safe breeding areas | Jeffries and Brunton, 2001 | ||
Griffon vultures (Gyps fulvus) | Relocation | Cliff paintings that mimicked droppings attracted vultures to nest on suitable cliffs | Sarrazin et al., 1996 | ||
Fish | White sturgeon (Acipenser transmomtanus) | Reduce entrapment and entrainment | Behavioural guidance of age-0 white sturgeon using coloured and strobing lights | Ford et al., 2018 | |
Invertebrate | Mayflies (Ephemeroptera), stoneflies (Trichoptera), dolichopodid dipterans, and tabanid flies (Tabanidae) | Ameliorate sensory trap | Fragmenting the solar-active area of solar panels reduced attractiveness of these panels to aquatic insects | Horváth et al., 2010 | |
Reptile | Green sea turtle (Chelonia mydas) | Ameliorate sensory trap | New dimmer, amber lights on Florida beaches reduced misguidance of sea turtle hatchlings away from the ocean | Witherington et al., 2014 | |
Green sea turtle (Chelonia mydas) | Reduce bycatch | Bycatch of turtles in commercial bottom gillnet fisheries reduced through use of LED and chemical light stick deterrents. | Wang et al., 2013 | ||
Audition | Bird | Black-capped vireo (Vireo atricapilla) | Relocation | Playing recordings of conspecific song attracted birds to more suitable habitats safe from brood parasitic species. | Ward and Schlossberg,2004 |
European starling (Sturnus vulgaris) | Reduce airstrikes | Use of sound frequencies to create a ‘sonic net’ to deter birds from airfields | Swaddle et al., 2016 | ||
Mammal | Harbour porpoise (Phocoena phocoena) | Reduce bycatch | Acoustic alarms successfully reduced bycatch of porpoises in gillnet fisheries, without reduced catch of target species | Larsen and Eigaard, 2014 | |
Fish | Asian carps (Hypophthalmichthys nobilis, H molitrix Valenciennes) | Invasive species control | Sound barriers effective at controlling spread of invasive Asian carps in the Great Lakes | Ruebush et al., 2012 | |
Multiple | Relocation | Playback of healthy reef sounds increased fish abundance and species richness in degraded coral reef habitat | Gordon et al., 2019 | ||
Chemoreception | Bird | Hooded plover (Thinornis rubricollis) | Reduce predation on threatened species | Conditioned taste aversion successful at reducing predation on threatened hooded plover eggs | Maguire et al., 2009 |
Mammal | Common goat (Capra hircus) | Invasive species control | Female goats captured, sterilized and put in a chemically induced estrus to release pheromones to attract males for ineffective mating. Eradicated invasive goats from certain Galapagos Islands | Cruz et al., 2009 | |
Fish | Sea lamprey (Petromyzon marinus) | Invasive species control | Pheromone-based trapping highly effective, species-specific, method of capturing invasive sea lamprey in the Great Lakes | Johnson et al., 2009 | |
Invertebrate | Gypsy moth (Lymantria dispar L.) | Invasive species control | Invasive gypsy moths in the USA have devasting effects of forests that can be effectively controlled with pheromone traps | Tobin and Blackburn, 2007 | |
Electroception | Fish | Hammerhead sharks (Sphyrna lewini) | Reduce bycatch | Commercial trawl fishing hooks made from electrorepulsive metals successful at reducing bycatch of sharks | Hutchinson et al., 2012 |
This table summarizes case studies where sensory ecology has been demonstrated to benefit conservation or wildlife management. We summarize relevant literature from all sensory modalities (vision, olfaction, chemoreception, electroreception and magnetoreception), across six major taxa (birds, mammals, fish, invertebrates, reptiles and amphibians) where valid case studies exist. We note that no relevant literature was found for amphibian species.
