  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 The lunar cycle determines availability of coral-reef fishes at fish markets Type Journal Article
  Year 2012 Publication Journal of Fish Biology Abbreviated Journal J Fish Biol  
  Volume 81 Issue 6 Pages 2074-2079  
  Keywords Animals; Commerce; Coral Reefs; *Fishes; *Moon; Philippines; Seafood/*statistics & numerical data  
  Abstract During 139 visits between March 2009 and May 2011, it was found that the availability of reef fishes at a local fish market in the Philippines was highly affected by the lunar cycle. The number of vendors selling reef fishes was significantly lower (13.4%) during third lunar quarters (full moon periods) than during the first, second and fourth lunar quarters (40.2, 25.0 and 30.0%, respectively). It is recommended that the influence of the lunar cycle on fish availability is considered when designing sampling strategies for catch surveys.

  Title Diel vertical migration of freshwater fishes – proximate triggers, ultimate causes and research perspectives: Diel vertical migration in freshwater fishes Type Journal Article
  Year 2012 Publication Freshwater Biology Abbreviated Journal  
  Volume 57 Issue 7 Pages 1342-1359  
  Keywords diel vertical migration; *Fishes; freshwater fish  
  Abstract 1. Diel vertical migrations (DVM) are typical for many cold-water fish species such as Pacific salmons (Oncorhynchus spp.) and coregonids (Coregonus spp.) inhabiting deep lakes. A comprehensive recent overview of DVM in freshwater fish has not been available, however.

2. The main proximate trigger of DVM in freshwater fish is the diel change in light intensity, with declining illumination at dusk triggering the ascent and the increase at dawn triggering the descent. Additional proximate cues are hydrostatic pressure and water temperature, which may guide fish into particular water layers at night.

3. Ultimate causes of DVM encompass bioenergetics efficiency, feeding opportunities and predator avoidance. None of these factors alone can explain the DVM in all cases. Multi-factorial hypotheses, such as the ‘antipredation window’ combined with the thermal niche hypothesis, are more likely to explain DVM. It is suggested that planktivorous fish move within a layer sufficiently well illuminated to capture zooplankton, but too dark for predators to feed upon the migrating fish. In complete darkness, fish seek layers with a temperature that optimises bioenergetics efficiency. The strength of each factor may differ from lake to lake, and hence system-specific individual analyses are needed.

4. Mechanistic details that are still poorly explored are the costs of buoyancy regulation and migration, the critical light thresholds for feeding of planktivorous and piscivorous fish, and predator assessment by (and size-dependent predation risk of) the prey fish.

5. A comprehensive understanding of the adaptive value of DVM can be attained only if the behaviour of individual fish within migrating populations is explicitly taken into account. Size, condition and reproductive value differ between individuals, suggesting that migrating populations should split into migrants and non-migrants for whom the balance between mortality risk and growth rate can differ. There is increasing evidence for this type of partial DVM within populations.

6. Whereas patterns of DVM are well documented, the evolution of DVM is still only poorly understood. Because experimental approaches at realistic natural scales remain difficult, a combination of comprehensive data sets with modelling is likely to resolve the relative importance of different proximate and ultimate causes behind DVM in fish.

  Title Dark Sky Parks – new impulse for nature tourism development in protected areas (National Park Muranska Planina, Slovakia) Type Journal Article
  Year 2016 Publication e-Review of Tourism Research Abbreviated Journal eRTR  
  Volume 13 Issue 5/6 Pages 536-549  
  Keywords Society; tourism; astrotourism; sustainable tourism; dark sky parks  
  Abstract Dark Sky Parks are one of important measures to support nature tourism in the protected

areas. In this paper, we introduce the concept of astro-tourism on the model area of National Park Muranska Planina (Slovakia), which should lead to the establishment of Dark Sky Park and the implementation of measures focused on dark sky protection, i.e. the elimination of light pollution over model area. The concept includes the measurement of night sky brightness, the selection of suitable observational sites and lighting plan. It is very important from the view of ecology, e.g. by the protection of night animal species. On the other hand, these characteristics can be fully used in new tourism concept in that protected area.

  Title Response of Migratory Sea Lampreys to Artificial Lighting in Portable Traps Type Journal Article
  Year 2012 Publication North American Journal of Fisheries Management Abbreviated Journal North American Journal of Fisheries Management  
  Volume 32 Issue 3 Pages 563-572  
  Keywords lampreys; Petromyzon marinus  
  Abstract This study evaluated responses by migratory spawning-phase sea lampreys Petromyzon marinus to artificial trap lighting in the laboratory and field with the aim of improving trapping as a method of sea lamprey control in the Laurentian Great Lakes. We hypothesized that lighting would improve trap success by increasing the attraction to, entrance into, or retention within portable sea lamprey traps. The responses of migratory sea lampreys to nocturnal lighting were complex and situation dependent. In the laboratory, where two traps were placed side by side, more sea lampreys were caught in the lit trap than in the unlit trap (80% versus 20%), largely because of increased attraction to the lit trap (75% of trap funnel entries by sea lampreys were in lit traps). In the field, where two traps were set 9 m apart and located against a barrier to upstream movement, there was no consistent difference in the numbers of sea lampreys caught in lit versus unlit traps. We provide two hypotheses for the variability in response to trap lighting between the laboratory and field, but overall the inconsistency of sea lamprey response to trap lighting leads us to conclude that the benefits of implementing trap lighting for sea lamprey control are limited. Lighting traps may be beneficial in situations where lighting is implemented in conjunction with other trap modifications that attract sea lampreys to within close proximity of traps or when traps are operated in stream locations that already encounter high volumes of sea lampreys.
