Personality of red squirrels and adaptation to urbanization<\/h3>\n

Many wild animals have invaded and adapted to urban areas with the increase in urbanization. Recently it has been understood that such animals have specific behaviors or life histories. I will try to determine why such animals can adapt and how they cope with man-made environments, focusing on the behavior and personality of Eurasian red squirrels. \u201cBe excited with the wonder of animals!!\u201d<\/p>\n

Behavioral mechanisms of inter-specific\u00a0mating<\/h3>\n

I joined here since 2016 as a PhD course student. My research interests are: (1) function of mutual ornament in Far Eastern daces (genus\u00a0Tribolodon<\/em>) and (2) how individual characteristics & conditions affect\u00a0their propensity for hybridization. I’ve worked on anatomy & conservation\u00a0genetics on several fishes during BS & MS courses, but I’m\u00a0broadly interested in ecology & evolution. Experiments are mostly conducted\u00a0on Far Eastern daces but I’m planning to do experiments also in nine-spine\u00a0sticklebacks.<\/p>\n

Statistical modeling in ecology and evolution<\/h3>\n

Ecologists and evolutionary biologists should not be satisfied only with fieldwork; it\u2019s just a data collection,\u00a0we need inferences.
\nHowever, picking up useful information from noisy and confounding data like we meet is one of the most challenging tasks in statistics.\u00a0I\u2019m developing methodologies for more credible and accurate inferences in these entangling situations and applying them to real ecological data.<\/p>\n

Effects of ectoparasites on migration behaviour in salmonids<\/h3>\n

My name is Christopher Ayer, I am a Canadian grad student interested in freshwater parasites and their ecology. This is my first time researching fish and aquatic ecosystems and I’ve learned much in just the few months since my arrival. While this isn’t my first time to Japan, I am thankful for the welcoming attitude of my lab-mates and all the guidance I have received studying here.<\/p>\n

Urban parasitology in small mammals<\/h3>\n

I have a deep and passionate love for animals and nature, and want to help protect every bit of it I can before we destroy what little we have left. My current research falls into the realm of Urban Parasitology, an emerging field of study. I\u2019m now investigating how the urban environment affects parasite community and prevalence within wildlife populations. I\u2019m interested in how these changes potentially impact conservation efforts of endangered species as well as human health.<\/p>\n

Nature is unimaginably complex, and we as humans tend to forget that we are part of it, that we are another member in the community of organisms. Every time we change or destroy part of it, it affects us, even if we don\u2019t realize it. Therefore, conservation is about far more than just protecting nature simply for its beauty. I can only hope that my research helps to spark a paradigm shift in the way the public views conservation, as well as public policy and urban development so that we can create a more sustainable society that is friendlier to nature.<\/p>\n

Brown bear digging for cicada\u00a0nymphs<\/h3>\n

\u00a0 \u00a0I’ve been interested in the ecological roles (e.g. ecosystem engineer) of terrestrial animals, especially, the brown bear<\/strong>. In undergrad, I studied on brown bear population trends<\/strong> in northern part of Hokkaido, Japan (as a cooperative research). Since postgraduate course, I’ve studied\u00a0brown bear digging for cicada nymphs<\/strong>. In the Shiretoko Natural Heritage, eastern part of Hokkaido, brown bears have started digging for cicada nymphs since 2000. I’m investigating the reason why bears start digging for cicada nymphs and their ecological function of soil disturbance. (More details are shown in my personal page.)<\/p>\n

\u00a0 Since\u00a02020, I start another project on belowground species interaction between plant roots and root feeders (e.g. cicada & grub, nematode).<\/p>\n

Theme\u00a0under construction<\/h3>\n

My undergraduate major was engineering, but the lectures in ecology I took during my exchange program to Canada fascinated me and led me here Hokkaido. I haven\u2019t decided my thesis yet, but I\u2019m currently interested in social learning and its mechanism in animals. I hope my study here leads to a good and interesting research.<\/p>\n

Why long-clawed shrew (Sorex unguiculatus<\/em>) has giant penis?<\/h3>\n
My research interest is mainly about mammal\u2019s behavioral ecology. Under long time consideration and discussion, now my research project is unraveling the function of long-clawed shrew\u2019s huge penis (almost 40% of its body size!!) and mating behaviors. Why do overwintered sexually matured males have big penis compared with juveniles? How do they use their penis for mating? Have female genital organs co-evolved with males organs? Is male huge penis a trait evolved through sexual selection, or just a case of allometry? How about other shrews\u2019 mating behavior and sexual organs?<\/div>\n
\u00a0 Countless questions need to be answered! I am going to use most of previous data form others and some of new data from myself for statistical analysis. Then, if I am lucky enough for having enough shrews\u2014 use them for the experiment: mating behaviors organization.<\/div>\n

I\u2019m interested in the phylogeography, because this analysis shows us the specie\u2019s historical processes.\u00a0So, I came to Hokudai to study the phylogeographyof crayfish worms that live on the body of endangered Japanese crayfish.\u00a0I\u2019m excited to conduct field and lab works in the great nature of Hokkaido.<\/p>\n

Squirrel\u2019s cognition<\/h3>\n

My research interest broadly lies in the evolution of cognition, with a more specific focus on animal learning, behaviour and cognition. I understand how do different factors (e.g. urbanization) may shape different cognitive performance, using squirrels as my primary study model. To understand animals\u2019 mind and behaviours, I conduct both laboratory and field studies. See my webpage for more details here (PKAC personal website<\/a>).<\/p>\n

Habitat segregation in stream salmonids: thermal effects on intra- and interspecific competition<\/strong><\/h3>\n

My research area is behavioral ecology, and I focus on studying mechanisms that cause variation in behavior, growth, stress responses and survival of stream salmonids. I am currently studying how factors of the physical and social environment affect the competitive abilities of Dolly Varden and white-spotted charr. Previously, I have worked with both basic and applied aspects of stream winter ecology, using brown trout as test species. I am also interested in stream habitat restoration and eel conservation.<\/p>\n

Hybridization between introduced trout and native charr<\/h3>\n

Brook trout, an invasive species, is frequently interbreeding with native white-spotted charr in Furano, Hokkaido. This hybridization may have negative impacts for native charr. I am especially interested in how the traits of individuals contribute to interbreeding and population persistence. Thus, I am studying the changes in distribution of brook trout, white-spotted charr, and their hybrids. My field work also includes individual-based traits and hybridization effects on their fitness using molecular analysis.<\/p>\n
