Science researchers' study, published online in <a href="http://link.springer.com/article/10.1007%2Fs10071-016-1043-9"><em>Animal Cognition</em></a>, tested the monkeys using jars of desirable peanuts and undesirable pellets in different ratios to prove they can reason about relative amounts, as opposed to just making straightforward comparisons about quantities.&nbsp;The 19 monkeys who participated in the study are from the 鈥楲iving Links to Human Evolution鈥 Research Centre at the Royal Zoological Society of Scotland, Edinburgh Zoo, UK.</p> <p>The study also demonstrated that the monkeys 鈥 like great apes 鈥 &nbsp;share a capability once thought to be uniquely human.</p> <p>鈥淚t might be that they are not that very different from us at all,鈥 says Buchsbaum, adding that in a sense, the results also further our understanding of ourselves as humans.</p> <p>While it still leaves capuchin monkeys a long way from the talking hero apes of the popular movie series, the type of intuitive ability they demonstrated in the lab tests is a building block for complex thinking, such as understanding cause and effect, and language.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3096 img__view_mode__media_original attr__format__media_original" height="563" src="/sites/default/files/Capuchin_4.jpg" typeof="foaf:Image" width="750" loading="lazy"></p> <p>The researchers say infants use the same ability to understand other people鈥檚 goals and preferences.</p> <p>鈥淚 think the fact that monkeys do share this ability would make us potentially more optimistic that they might also be capable of more sophisticated social inferences,鈥 says&nbsp;Buchsbaum. 鈥淲hile monkeys are unlikely to be capable of learning language, the ability to track probabilities is absolutely related to language learning.鈥</p> <p>The statistical reasoning abilities shared by human infants and monkeys are part of a broader range of cognitive skills that encompass everything from predicting the behaviour of others to being able to reason about someone鈥檚 desires and mental state.</p> <p>Buchsbaum notes there are more immediate applications for this ability in monkeys such as how to forage and compete for food successfully.</p> <p>For now, the scientists are satisfied to add to their growing knowledge about the evolutionary traits of humans and other animals, particularly primates.</p> <p>Until recently, the ability to make inferences using probabilities was thought to develop relatively late in childhood. But recent work revealed this ability in infants as young as 10 months old to a one year old.</p> <p>Other research suggests that great apes such as chimpanzees, gorillas and orangutans also share this intuitive statistical ability with human infants.</p> <p>What鈥檚 intriguing about the monkey study is it suggests that this ability developed earlier on the ancestral tree&nbsp;before apes and&nbsp;humans&nbsp;branched off, Tecwyn says.</p> <p>Humans shared a common ancestor with chimps about six million years ago. But we last shared a common ancestor with capuchin monkeys about 30 million years ago.</p> <p>鈥淪o we could make the inference that this ability is at least that ancient,鈥 Tecwyn says.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3097 img__view_mode__media_original attr__format__media_original" height="563" src="/sites/default/files/Capuchin_5.jpg" typeof="foaf:Image" width="750" loading="lazy"></p> <p>It is possible&nbsp;but unlikely, that statistical reasoning is a trait capuchins evolved independently, and it is not shared by other monkey species, adds Buchsbaum.</p> <p>鈥淕iven that humans, apes and capuchins all share the trait, it is more likely that it evolved once earlier rather than independently in these different groups.鈥</p> <p>Researchers have long been on a quest to establish what makes humans unique from other animals&nbsp;and conversely, what cognitive abilities are shared.

It鈥檚 a history that coincides with the rise of American imperial power whose elites were competing with their contemporaries in Europe to build the biggest and best cultural institutions. Those elites envisioned zoos as orderly places of education, where the public could go to learn about animals.&nbsp;</p> <p>鈥淓arly zoos were organized in opposition to the little menageries of circuses and the world of P.T. Barnum, but it didn鈥檛 work,鈥 says Bender.&nbsp;</p> <p>鈥淶oo visitors didn鈥檛 follow the signs. They wanted to poke and feed the animals. Zoos were meant to be science labs for study, yet all people wanted to do was ride the animals.鈥&nbsp;</p> <p>Bender uses sources including archival documents, artifacts, books, films, memoirs and other materials such as souvenir postcards, maps and magazines to bring the history of zoos to life. But it wasn鈥檛 always easy gaining access to zoo archives.&nbsp;</p> <p>鈥淪ome zoos were great. Others outright told me I would never get to see their archives,鈥 he says. 鈥淚t became a challenge to get into these archives and shed a light on a history many were intent on keeping in the closet.鈥&nbsp;</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2547 img__view_mode__media_original attr__format__media_original" height="493" src="/sites/default/files/2016-11-16-Zoo_Parade-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>The 福利姬自慰Scarborough library has digitized parts of&nbsp;Marlin&nbsp;Perkins' Zoo Parade Board game</em></p> <p>It鈥檚 impossible to talk about the history of zoos without looking at the wild animal trade, notes Bender. He recalls Frank Buck, an American icon during his time, but someone who would be judged as appalling by modern standards. Buck was heavily involved in the animal trade and created a celebrity persona around capturing animals in the wild. In reality, notes Bender, he was buying animals from markets in Singapore and shipping them to America. &nbsp;</p> <p>鈥淎s he was doing this he also spun these imagined tales and created this image of animal capturers as brave men.鈥</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2549 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/2016-11-16-Zoo_Parade-1_0.jpg" style="width: 150px; height: 657px; float: right; margin: 10px;" typeof="foaf:Image">Buck鈥檚 movies were very popular during the interwar period and heavily influenced western perceptions of jungles as wild, untamed places filled with 鈥渟avage鈥 people&nbsp;and dangerous animals. They also contained 鈥渉orrific鈥 animal fights that were staged for the camera.</p> <p>Many of the artifacts collected for the book have been <a href="http://digitalscholarship.utsc.utoronto.ca/projects/islandora/object/animalempire:root">digitized by the 福利姬自慰Scarborough library</a>. One of these is the Marlin Perkins' Zoo Parade board game, which involves capturing animals in the wild and shipping them to America. The game has also been <a href="http://digitalscholarship.utsc.utoronto.ca/ZooParade/">programmed to play online</a> and also features interactive photos highlighting important events in zoo history.</p> <p>Bender notes that during the Cold War period, popular culture turned its attention towards the nuclear family of the 1950s. The wild animal trade was slowly being outlawed, thus zoos began looking more into their breeding programs. This not only maintained their stock of animals, it also attracted visitors eager to see baby monkeys, lions and elephants. &nbsp;</p> <p>While the debate over the true place of zoos continues 鈥&nbsp;dominated by animal rights advocates on one side and by those committed to the conservation of wild animals on the other 鈥&nbsp;there鈥檚 no denying the importance zoos play in shaping popular attitudes towards animals.</p> <p>Bender points to the popularity of chimpanzee shows of the early 20th century as a prime example. These vaudeville shows with often racist aspects were adopted by zoos and became big money makers. By the 1980s most accredited zoos across the U.S. had all but decided to put an end to them, not because the public didn鈥檛 want them, but because zoos no longer wanted to display their animals that way.&nbsp;</p> <p>鈥淭he aim of the book is to shed a light on the uncomfortable aspects of zoo history while also recognizing their enduring place as important cultural institutions,鈥 he says. &nbsp;&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 16 Nov 2016 21:56:13 +0000 ullahnor 102430 at Why some hummingbirds balloon up before they fly south: 福利姬自慰research /news/why-some-hummingbirds-balloon-they-fly-south-u-t-research <span class="field field--name-title field--type-string field--label-hidden">Why some hummingbirds balloon up before they fly south: 福利姬自慰research</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=VrOrQFCh 370w, /sites/default/files/styles/news_banner_740/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=M6Ho50LB 740w, /sites/default/files/styles/news_banner_1110/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=j4Zq4NRq 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=VrOrQFCh" alt="Photo of hummingbird"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>ullahnor</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2016-10-13T14:14:29-04:00" title="Thursday, October 13, 2016 - 14:14" class="datetime">Thu, 10/13/2016 - 14:14</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">A ruby-throated hummingbird (Photo by Ken Jones)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/don-campbell" hreflang="en">Don Campbell</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Don Campbell</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/biology" hreflang="en">Biology</a></div> <div class="field__item"><a href="/news/tags/u-t-scarborough" hreflang="en">福利姬自慰Scarborough</a></div> <div class="field__item"><a href="/news/tags/utsc" hreflang="en">UTSC</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> <div class="field__item"><a href="/news/tags/animal" hreflang="en">Animal</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Some adult ruby-throated hummingbirds choose to pack on significant weight in the four days before their long migratory flights south for the winter, a new 福利姬自慰study has found.&nbsp;</p> <p>鈥淢any different birds fatten up before they migrate, but we wanted to know what specific strategies hummingbirds use to fuel up prior to migration,鈥 says <strong>Ken Welch</strong>, an associate professor of biological sciences at 福利姬自慰Scarborough.&nbsp;</p> <p>鈥淚t turns out that individual hummingbirds make individual decisions 鈥 some fatten up for long flights, while others stop and fuel along the way.鈥&nbsp;</p> <p>Welch and master's student <strong>Lily Hou</strong> developed a unique system to track and weigh hummingbirds in the wild before migration using radio frequency identification tags. Every&nbsp;bird had a microchip and was weighed each time it&nbsp;landed on a balance attached to the feeder. &nbsp;</p> <p>Hummingbirds that fatten up spent more time at feeders in order to gain weight rapidly, the researchers found 鈥&nbsp;in some cases putting on as much as 35 to 40 per cent of their body mass in the four days before migration. They also found that no juvenile birds were fattening, meaning that those choosing to spend more time at feeders&nbsp;had made the migratory trip at least once.&nbsp;</p> <p>鈥淭his suggests fattening could be a learned behaviour,鈥 says Welch.</p> <p>The findings add to a growing body of research that suggests&nbsp;pre-migration strategies for some birds&nbsp;are affected by age and experience, he says.&nbsp;</p> <p>&nbsp;</p> <p><iframe allowfullscreen frameborder="0" height="315" src="https://www.youtube.com/embed/Lfias345XpU" width="560"></iframe></p> <p>Birds generally use two strategies when it comes to preparing for migration. One prioritizes fattening to allow a more direct flight in order to arrive at the wintering grounds quickly. The other involves shorter flights, stopping and feeding along the way.&nbsp;</p> <p>There are advantages to both, notes Welch. Short trips can be a safe strategy as long as resources can be found reliably along the way, but it can take longer to arrive at the final destination. For other birds, fattening may be necessary to take longer flights over large ecological barriers like oceans or deserts.&nbsp;</p> <p>鈥淭he reason some hummingbirds fatten up before their long flight may be to gain an advantage over potential rivals 鈥 by arriving at their wintering grounds in southern Mexico and Central America quickly they can establish territories and control the best resources,鈥 he says.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2234 img__view_mode__media_original attr__format__media_original" height="497" src="/sites/default/files/hummingbird3-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>(hummingbird approaching a feeder, photo by Ken Welch)</em></p> <p>During breeding season, hummingbirds generally only increase their eating activity in the evening before fasting for the night, while reducing it in the middle of the day.
