Hearing sensitivity was determined utilizing the auditory brainstem response (ABR) recording technique. Measurements in the frequency range between 0.2 and 4.0 kHz were conducted prior and directly after noise exposure as well as after 3, 7, and 14 days of recovery. Both species showed a significant loss of sensitivity (up to 26 dB in C. auratus and 32 dB in P. pictus) immediately after noise exposure, with the greatest hearing loss in the range of their most sensitive frequencies. Hearing loss differed between both species, and was more pronounced in the catfish. Exposure duration had no influence on hearing loss. Hearing thresholds of C. auratus recovered within three days, whereas those of R. pictus only returned to their initial values within 14 days after exposure in all but one frequency. The results indicate that hearing specialists are affected differently by noise exposure and that acoustic communication might be restricted in noisy habitats. Notes: J. Acoust. Soc. Am.

Journal: Journal of Experimental Biology Volume: 208 Issue: 18 Pages: 3533-3542 Short Title: Are hearing sensitivities of freshwater fish adapted to the ambient noise in their habitats? Accession Number: ISI:000232546800015 Keywords: FISH; HEARING SPECIALIZATIONS; EVOLUTION; MASKING; AMBIENT NOISE; AUDITORY EVOKED POTENTIAL; FRESHWATER; CARP; CYPRINUS CARPIO; PERCH; PERCA FLUVIATILIS Abstract: In the aquatic environment, hearing is an important sense for the survival of an animal. Sound travels faster and is much less attenuated in water than in air, making it the perfect means for communication over long distances (Hawkins and Myrberg, 1983; Rogers and Cox, 1988). By listening to the background noise in an aquatic habitat, an animal can get biotic information about the position of prey or predators, potential mates or competitors, as well as abiotic information about currents, coastlines, torrents, wind, etc. (Popper and Fay, 1993; Lagardère et al., 1994). On the other hand, this ambient noise impairs the detection of signals (Hawkins and Myrberg, 1983; Mann and Lobel, 1997). Studies investigating or mentioning the acoustic characteristics of various aquatic habitats often focus on marine environments (e.g. Wenz, 1962; Cato, 1976; Urick, 1983; McConnell et al., 1992; Samuel et al., 2005), including reefs (Tolimieri et al., 2004; Egner and Mann, 2005). Knowledge about ambient noise spectra of freshwaters (lakes, ponds, rivers) is sparse (Bom, 1969; Boussard, 1981; Lugli and Fine, 2003; Lugli et al., 2003; Amoser et al., 2004). Teleost fishes have evolved an astonishing diversity in hearing abilities. Hearing non-specialists or generalists such as several groups of fishes, among them two thirds of all freshwater fishes, have developed hearing specializations that enhance auditory sensitivity and broaden frequency ranges compared with hearing non-specialists (generalists), which lack such adaptations. It has been speculated that the enhanced sensitivities of these so-called hearing specialists have evolved in quiet habitats such as lakes, backwaters of rivers, slowly flowing streams or the deep sea. To test this hypothesis, noise levels and frequency spectra of four different freshwater habitats near Vienna, Austria (Danube River, Triesting stream, Lake Neusiedl, backwaters of the Danube River), were recorded and played back to native fish species while simultaneously measuring their auditory thresholds using the auditory evoked potential (AEP) recording technique. As a representative of hearing specialists, we chose the common carp (Cyprinus carpio, Cyprinidae) and for the hearing generalists the European perch (Perca fluviatilis, Percidae). Data show that the carp’s hearing is only moderately masked by the quiet habitat noise level of standing waters (mean threshold shift 9 dB) but is heavily affected by stream and river noise by up to 49·dB in its best hearing range (0.5–1.0 kHz). In contrast, the perch’s hearing thresholds were only slightly affected (mean up to 12 dB, at 0.1 kHz) by the highest noise levels presented. Our results indicate that hearing abilities of specialists such as carp are well adapted to the lowest noise levels encountered in freshwater habitats and that their hearing is considerably

  • Whale Conservation in Coastal Ecuador : Environmentalism of the Poor Or Neoliberal Conservation ?*
    Revista Iberoamericana 25.2 (2014 ): 1-33. Whale Conservation in Coastal Ecuador : Environmentalism of the Poor or Neoliberal Conservation ?* Bradley Tatar Ulsan National Institute of Science and Technology [UNIST] Tatar, Bradley (2014), Whale Conservation in Coastal Ecuador: Environmentali sm of the Poor or Neoliberal Conservation? In this p aper, I examine the interaction between transnational activist Abstract networks, conservation scientists, government authorities, and artisanal fish ing communities in coastal Ecuador. Focusing on the problem of cetacean bycatch, I employ the concept of the “discourse of nature” to identify contrasting languages of valuation used by the stakeholders for marine coastal environments. NGOs utilize a scientific evaluation to portray artisanal fishing as a hazard to the survival of hum pback whales, but this coincides with the attempt by government and development agencies to portray artisanal fisheries as inefficient and ecologically harmful. In contrast, a survey I carried out in a coastal fishing community shows that local residents contest this portrayal of fishing as ecologically harmful, drawing upon their discourses of livelihood, indigenous identity, territorial claims, and social marginality. Focusing on the social conflict surrounding the marine protected area [MPA] of Machalilla National Park, I argue that additional restrictions on fishing to mitigate the incidence of cetacean bycatch will not have adequate social acceptance by local artisan fishing communities. Hence, the language of whale conservation which appears to be a pro-poor environmentalism at the macro (international) level, appears to local actors as a threat to their livelihoods. To offset this micro/macro discrepancy, whale conservation NGOs should support local aspirations to continue fishing as a livelihood, thereby * This work was supported by the National Research Foundation of Korea Grant funded by the Korean Government (NRF-2012S1A5A8024090).

  • The Regulatory Framework for Whales, Dolphins and Porpoises in European Waters
    The Regulatory Framework for Whales, Dolphins and Porpoises in European Waters Andrea Ripol, Seas At Risk, Brussels, Belgium and Mirta Zupan, Royal Belgian Institute of Natural Sciences and Ghent University, Belgium No EU citizen wants to eat fish that has been caught at the expense of iconic species like dolphins or whales. The legal framework to prevent the killing of marine mammals exists, now it is just a matter of political will to implement it. Andrea Ripol © Tilen Genov, Morigenos © Tilen Genov, 28 Overview of Cetacean Species in European Waters (including Red List Status) Introduction Interest in whale conservation began in earnest in the late 1940s largely as a response to the unsustainable pressure placed on whale populations by intensified commercial whaling. At first, the aim was to conserve populations in order to continue harvesting them. In the 1970s, as environmental activism heightened, several international agreements for nature protection were signed, including the Bern Convention on the Conservation of European Wildlife and Natural Habitats and the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Today, in addition, cetaceans in European Union (EU) waters are strictly protected by the EU‘s Habitats Directive, as well as the Marine Strategy Framework Directive, which intends to prevent human-induced decline of biodiversity, targets various pressures and threats and tries to achieve a good environmental status in EU waters. Legal framework in Europe Habitats Directive and the Natura 2000 network The protection of cetaceans in the EU is primarily driven by the Habitats Directive (Council Directive 92/43/EEC), a cornerstone of EU legislation for nature protection, adopted in 1992 (Council of the European Communities, 1992).

ISBN 0 642 21388 7 Published September 1996 © Copyright The Director of National Parks and Wildlife Australian Nature Conservation Agency GPO Box 636 Canberra ACT 2601 Cover illustration by Lyn Broomhall, Perth Copy edited by Green Words, Canberra Printer on recycled paper by Canberra Printing Services, Canberra Foreword It seems appropriate that Australia, once an active whaling nation, is now playing a leading role in whale conservation. Australia is a vocal member of the International Whaling Commission, and had a key role in the 1994 declaration of the Southern Ocean Sanctuary. The last commercial Australian whaling station ceased operations in Albany in 1978, and it is encouraging to see that once heavily exploited species such as the southern right and humpback whales are showing signs of recovery. Apart from the well-known great whales, Australian waters support a rich variety of cetaceans: smaller whales, dolphins, porpoises and killer whales. Forty-three of the world’s 80 or so cetacean species are found in Australia. This diversity is a reflection of our wide range of coastal habitats, and the fact that Australia is on the main migration route of the great whales from their feeding grounds in the south to warmer breeding grounds in northern waters.

How to Write a Letter to the Editor & Sample Letter 5. How to Write a Letter to your Representative and Sample Letter 6. Whale Tale Defending the Whales whales.greenpeace.org/us 1. Letter of Introduction Dear Students and Teachers, It’s amazing to think that it was over thirty years ago that Greenpeace first set out to confront the whalers and save the whales. Three decades later, the image of Greenpeace activists placing themselves in front of the harpoons and putting their bodies on the line to defend the whales remains as powerful as ever. And it remains our most effective technique for shutting down the whalers when we are on the front lines in the Antarctic whaling grounds. Even though most people don’t think so, thousands of whales are hunted each year across our oceans. But as crucial as it is to get between the whalers and their harpoons, there is much more to saving the whales than pounding through the waves in an inflatable boat. Because ultimately, an end to commercial whaling will only come about through political pressure on the countries that support it. And no country is better positioned to apply that pressure than the United States. The US has historically been among the leading voices defending the whales, and this year, with the International Whaling Commission (IWC) meeting in Alaska in May, there are signs that it is rediscovering that voice.

  • Buying Whales to Save Them | Issues in Science and Technology
    9/26/2018 Buying Whales to Save Them | Issues in Science and Technology Buying Whales to Save Them by Ben A. Minteer, Leah R. Gerber Current policy approaches to manage whaling and protect whales are failing. It’s time to try a new approach that combines economic pragmatism and ethical principles. Since the beginning of the conservation movement in the late 19th century, decisionmakers facing environmental issues have struggled to square the impulse to respect nature’s dignity with more anthropocentric calculations of economic utility. It is a task that has often divided scientists, ethicists, and advocates S who share a regard for biodiversity and ecological integrity, yet dier on how such goals are to be justied and promoted in policy discourse. This debate has evolved over the years as new conservation initiatives and policy proposals have taken center stage, but the core of the dispute remains relatively unchanged: Does viewing species and ecosystems as economic goods preclude seeing them as objects of moral duty? Will the use of economic valuation methods extinguish rather than encourage public support for environmental protection? Can conservation really be expected to succeed by ignoring economic incentives bearing on the protection of wild populations and ecosystems? A recent proposal to create a “whale conservation market” has highlighted this stubborn ethics/economics divide in a very visible and contentious way. The whale market or “whale shares” idea presents an alternative to the traditional regulatory approach. By calling for the establishment of quotas that could be bought and sold, it allows conservation groups as well as whalers to purchase a xed number of whale shares, thereby providing a mechanism for whale protection as well as managed harvest.
