Colorado voters will decide on Nov. 3 whether the state should reintroduce gray wolves (Canis lupus) after a nearly 80-year absence. Ballot Proposition 114 would require the state to develop and oversee a science-based plan to restore wolves, focused in Western Colorado and initiated by the end of 2023.

Clashing Values<p>Proposition 114 has strong support in Colorado. <a href="https://extension.colostate.edu/topic-areas/people-predators/public-perspectives-on-wolves-and-wolf-reintroduction-8-004/" target="_blank">Statewide surveys </a> conducted by phone, by mail and online over the past two decades have found that 66% to 84% of respondents supported reintroducing wolves. This support is consistent across different regions of the state and diverse demographic groups.</p><p>In a <a href="https://doi.org/10.7717/peerj.9074" target="_blank">survey of Colorado residents</a> that we conducted in 2019, the prospect that wolves could contribute to a balanced ecosystem was the most commonly cited reason for supporting reintroduction. Other arguments included people's cultural and emotional connections to wolves, and <a href="https://extension.colostate.edu/topic-areas/people-predators/moral-arguments-related-to-wolf-restoration-and-management-8-011/" target="_blank" rel="noopener noreferrer">moral arguments</a> that restoring a species humans had eradicated was the right thing to do.</p><p>While overall public support is strong, over half of Colorado's 64 counties have passed <a href="https://www.drovers.com/article/wolf-reintroduction-ballot-colorado" target="_blank" rel="noopener noreferrer">resolutions against restoring wolves</a>. Many ranching and hunting associations are actively campaigning against the ballot measure.</p><p>In our 2019 study, we found that media coverage in the state focused more strongly on <a href="https://doi.org/10.7717/peerj.9074" target="_blank" rel="noopener noreferrer">perceived negative impacts</a> associated with wolf reintroduction than on beneficial effects. Surveys show that resident concerns include threats to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-human-safety-8-003/" target="_blank" rel="noopener noreferrer">human safety and pets</a>; <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-livestock-8-010/" target="_blank" rel="noopener noreferrer">wolf attacks on livestock</a>; and the potential for wolves to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-big-game-and-hunting-8-001/" target="_blank" rel="noopener noreferrer">reduce deer and elk populations</a>, threatening hunting opportunities.</p>
Who Decides?<p>This measure is the first giving voters in the U.S. an opportunity to weigh in on bringing back a native species. Addressing the issue through a ballot measure adds a unique twist to public and media discussions about wolves.</p><p>Supporters call it a democratic way to ensure that the <a href="https://www.cpr.org/2020/09/29/should-wolves-be-brought-back-to-colorado-a-rancher-and-a-biologist-have-their-say/" target="_blank">public's values are recognized</a>. They also argue that voters are deciding only whether wolves should be reintroduced, while allowing experts at the <a href="https://cpw.state.co.us/" target="_blank" rel="noopener noreferrer">state wildlife agency</a> to create a reintroduction plan <a href="https://www.steamboatpilot.com/news/election/howl-you-vote-wolf-advocates-opponents-ask-colorado/" target="_blank" rel="noopener noreferrer">based on the best available science</a>.</p>

Finding Consensus<p>Studies suggest that ballot initiatives like 114 will <a href="https://doi.org/10.1016/j.biocon.2017.07.032" target="_blank">become more common</a> as public values toward wildlife change and more diverse groups seek to influence wildlife management. For us, the key question is how to recognize and incorporate these differing values as agencies make decisions.</p><p>Research drawing on insights from <a href="https://extension.colostate.edu/topic-areas/people-predators/dialogue-and-social-conflict-about-wolves-8-009/" target="_blank">psychology, political science and sociology</a> suggests that it is critical to run<a href="https://drive.google.com/file/d/1QppmBszEF6zsNnhBJ7Q2-pSWRR-Zx_ln/view" target="_blank" rel="noopener noreferrer"> truly participatory processes</a> that engage government agencies and people who have a stake in the issue in shared decision-making. Fostering dialogue between groups that value wildlife differently can build empathy and mutual understanding and <a href="https://doi.org/10.1016/j.biocon.2014.07.015" target="_blank" rel="noopener noreferrer">foster compromise</a>. Broadening the conversation in this way is essential for coexisting with carnivores with minimal impacts on predators and people.</p>

A blue whale can weigh as much as 200 tons and consume 12,000 pounds of krill in a single day. But even the largest animal on Earth doesn't stand a chance against a fast-moving cargo ship.
1. Acoustic monitoring instruments identify whale vocalizations. 2. Observers record whale sightings with a mobile app. 3. Oceanographic data is used to predict where blue whales are likely to be. 4. The data streams are compiled and validated. 5. Whale information is disseminated to industry, managers and the public. Nicolle R. Fuller, Sayo Studio<p><span style="background-color: initial;">There are three main components.</span><br></p><p>One is an acoustic listening station. Out in the Santa Barbara channel, our collaborators at Woods Hole Oceanographic Institution and Texas A&M University at Galveston deployed an acoustic buoy that has an underwater microphone near the seafloor. There's a small computer that processes any audio that the microphone picks up.</p><p>It is able to automatically detect the calls of blue, humpback and fin whales. Then there's a surface buoy with a satellite transmitter that sends that information back to shore. It's then validated by a scientist on shore before it's added to the database.</p><p>Then the second piece is a blue whale habitat model. We use oceanographic data like sea-surface temperature and current to predict where blue whales are likely to be on any given day. That was developed by our collaborators at U.C. Santa Cruz, the University of Washington and NOAA Southwest Fishery Science Center.</p><p>It's a dynamic model that's running every day in an automated fashion and producing maps that show us blue whale hotspots.</p><p>The third piece is data gathered by community scientists who are out on whale-watching and tourism boats nearly every day. They use mobile apps such as <a href="http://www.whalealert.org/" target="_blank">WhaleAlert</a> and <a href="http://whaleaware.org/index.php?page=download-spotter" target="_blank">Spotter Pro</a> to record whale sightings that are also added to the database.</p>
Deploying the acoustic detection system in the Santa Barbara Channel near the shipping lanes in 2019. Benioff Ocean Initiative<p>There are quite a few challenges, both on the technological side and just the bureaucratic side, of actually getting the data delivered that way. It's their main safety and navigation tool, so you don't want it to be crowded with too much data and information. That would need to be done really thoughtfully. But that's a communication pathway that could really help get this data more easily adopted.</p><p><strong></strong><strong>Right now there are voluntary slow-speed zones, but some ships aren't abiding by those recommendations. How likely do you think they'd be to adopt technology like Whale Safe?</strong></p><p>A few years ago there was actually a NOAA-led working group that brought together many stakeholders to try to develop solutions. One of the recommendations that came out of that process was actually a call for new technology and more real-time data on whale activity. And that was supported by many members of the shipping industry that were part of that working group.</p><p>That helped to inform the approach that we decided to take. Some of these companies expressed that time is money, and if they're going to slow down, they want to make sure that they're slowing down because there are actually whales in the area.</p><p>Our hope is that this data can really help to reinforce those slow-speed zones, especially when there's high whale activity in the channel.</p>

Days after federal data revealed taxpayers funded the killing of 1.2 million native animal species in 2019, the U.S. Department of Agriculture's Wildlife Services program was sued Thursday over what conservation advocates decry as a cruel and misguided annual extermination spree.

Pilot whales, sperm whales, beaked whales and deep-sea dolphins are the marine mammals most commonly involved in mass strandings. Baleen whales, on the other hand, a group to which all big whales except the sperm whale belong, strand very rarely.
How Do Whales and Dolphins Navigate?<p>Like <a href="https://www.dw.com/en/the-science-of-migratory-birds/a-47812308" target="_blank" rel="noopener noreferrer">migratory birds,</a> some whale species travel great distances every year. In winter, whales migrate from the cold northern seas to warmer waters in the south, and whales from southern waters move to the north in the same season. Months later, they then begin to travel back home.</p><p>The smaller toothed whales, such as dolphins, have a powerful underwater sonar. They orient themselves on their journeys by emitting sound waves in the form of clicking noises. When these sound waves collide with an object, they are reflected back as echoes to the animals' ears, which in the case of whales are shielded from the skull in foam-filled chambers inside the body to enable spatial hearing. The faster the sound returns, the closer the prey, an obstacle or the coast.</p><p>However, in the case of the large baleen whales, which have horn plates (baleen) instead of teeth in their upper jaws for filtering krill, animal plankton and small fish from the water, this underwater sonar is not very highly developed.</p><p>This echolocation works very well as a rule. However, sound reflection does not function reliably in certain circumstances, particularly when there are shallow or semicircular bays, sandy underwater embankments or silt banks. These types of coasts and obstacles do not produce an unambiguous echo from any particular direction, so the warning system fails.</p>
What Influence Does the Earth's Magnetic Field Have?<p>Whales such as the pilot whale do not use just underwater sonar to orient themselves, but — again, like migratory birds — seem to rely on the lines of the earth's magnetic field, as their migration routes often run parallel to those lines. The slight fluctuations of the earth's magnetic field appear to function like a kind of map.</p><p>Magnetite crystals have been found in the skulls of these animals. The whales could be confused by disturbances of the geomagnetic field near the coast. Magnetic fields running perpendicular to the mainland are also thought to play a role in mass strandings of whales in certain coastal regions.</p><p>Every few years, solar storms and sunspots that occur amid heightened activity on the sun's surface also cause fairly large changes in the Earth's magnetic field. It is at such times that sperm whales, for example, which also use geomagnetism as a natural navigation system, get lost and become stranded in the North Sea.</p>
Why Do Whales and Dolphins Become Stranded?<p>Navigational errors are thus believed to be the main cause of whale strandings, but all the reasons have not yet been conclusively investigated.</p><p>One of them is certainly the social behavior of many whale species, which travel in groups, so-called pods, and are guided by a leader. For example, in the case of sperm whales, a male leads the way from the Arctic Ocean back into warmer waters. By contrast, when orcas are on their travels, a mother or grandmother leads the group.</p><p>If leaders lose their orientation, perhaps because they are confused or because parasites have attacked their ears, rendering them incapable of hearing the echoes of the clicking sounds that have been sent, the accompanying animals will follow them in the wrong direction. If a leader is stuck in shallow waters, the rest of the group stays with it, even if this means their certain doom.</p><p>Sometimes, as has been observed, for example, with orcas on the South African coast, this group cohesion can go so far that whales who have already been saved after a mass stranding return to the beach if another stranded whale calls for help.</p><p>But strandings can also have other natural causes. Sometimes, smaller dolphins become beached because they have taken refuge from orcas and other predators in shallower waters or because they have ventured too far into shallow areas when hunting shoals of fish.</p><p>Occasionally, individual animals are also washed ashore dead after being previously injured by collisions with ships, fishing nets or shark attacks or becoming ill from infections or parasite infestation. </p>
Which Human Influences Exacerbate the Situation?<p>In addition to natural factors, man-made underwater noise from ships, icebreakers, drilling platforms or military sonar equipment can also massively impair the orientation and communication of marine mammals. They flee the strong sound waves in a state of confusion. And since the density of water is much higher than that of air, sound propagates underwater about five times faster than in the air.</p><p>Military sonar operations employing very loud sounds have particularly drastic effects. After NATO maneuvers, for example, beaked whales have washed up dead on the coasts of Cyprus, the Canary Islands and the Bahamas. The sonars, which are louder than 200 decibels, triggered the formation of gas bubbles in the blood vessels and organs of marine mammals (as happens with diving sickness), obstructing the blood supply and leading to their death. </p>
How Can You Help Stranded Whales and Dolphins?<p>When a whale stranding is discovered, there is usually not much time left. Teams of helpers can do little more than try to cool the stranded animals, keep them moist and combine forces to get the heavy animals back into the sea as quickly and gently as possible.</p><p>In some countries, hotlines have been set up so that as many helpers as possible can be mobilized quickly. For many exhausted animals, however, even these immediate measures often come too late. </p>
