Next WeekOutline of Current Lecture I. Wild Rockies Field InstituteII. Human Impacts: H.I.P.P.O AcronymCurrent LectureWild Rockies Field Institute: think outside the classroom What we do… Academic, field-based courses for college students Hands-on, experiential learning 6 courses, a variety of academic departments WRFI Mission: broaden the nature of a liberal arts education through experiential learning Teach: critical thinking Foster understanding for: Natural and human communities An interdisciplinary approach to applying your education You can take what you learn into the field and apply it to what you’re learning in the classroom Welcome to your classroom… Rigorous Academic Inquiry + Backcountry Travel + Field Trips=Wild Rockies Field Institute Personalized learning + experienced faculty =happy students Small group size (10 students) =5:1 student to instructor ratio Academic credit: the nitty-grittyThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Upper division college credit form the University of Montana Consult with your advisor to determine how the credits transfer towards your degree 700+ students from over 240 institutions have completed WRFI courses Academic departments include: Environmental Studies, Geography, Natural Resources, Native American Studies, Science and Philosophy Semester courses: 15 credits in 9 weeks Montana Afoot and Afloat: Human/Land Relations Colorado Plateau: Desert Canyons and Cultures Wild Rockies Summer Program Short summer Courses: what are your plans next summer? Cycle the Rockies: Energy and Climate change in Montana Environmental Ethics Restoration Applying and Paying for a WRFI course: Finances Check with your Financial Aid Office about accessing your Federal aid for off-campus programs Several scholarships available through WRFI Payment plans and alternative funding options also available Application process Find the application on our website: email or snail mail, either works Rolling admission=first come, first serve (up to 10 students) Get your application in ASAP Lunch and Learn Information Session Tuesday, October 14, 12pm-1pm, Science Hall, Room 15 WRFI Contact: Bethany Applegate Instructor and outreach manager [email protected] 406-549-4336 Information will be on Moodle Human Impacts: H.I.P.P.O Acronym Habitat Loss Invasive species Pollution Population (of humans) Overharvesting Habitat loss and fragmentation Example: People are encroaching on space in the tropical rainforest in South America Overtime, habitat loss leads to fragmentation/isolated pockets of habitats  In between highways and subdivisions and cities are small habitats This causes problems because larger animals have to cross through highways and subdivisions  This impacts small things such as plants, as well - Sometimes pollinators don’t fly well and getting from patch to patch of plants on isolated landscapes can be problematic; the plants’ genes won’t flow - Seed dispersal won’t get very far Altering an ecosystem’s process also effects habitat There is habitat loss on the gulf coast because we’ve trenched the Mississippi river tomake it easier on boats and to subdue flooding. By not letting the river take its own course, we’re not getting the outflow of silt that maintains and builds coastal landscapes.  Invasive / Non-native species Clicker Question: The arrival of a non-native species is always a problem on the existing ecosystem. T/F Most people said False. A lot of times, environmental conditions are not going to allow an invader to really take hold. They’re not ALWAYS a problem. They’re more likely to not be a problem. Invasive Species- Invasive species can survive in a new location often lacking their natural predators or competitors Lion Fish: They’re typically found in the Indian and Pacific Ocean, but now they’re popping up all over the Eastern Seaboard and moving down the coast of South America. - There are two theories as to how they got there:- Hurricane Andrew: It did a lot of damage to an aquarium where they had a tank full of lion fish that disappeared during the hurricane; they may have gotten lose into the ocean- Flush Down the Toilet: A lot of people keep big aquariums and then get boredwith it and dump them down the drain or “set them free” in the ocean. This is a poor approach to getting rid of something that’s not native.- We’ve now released this predator into the environment and there are a lot of negative consequences:- They take out beta fish- Their spines are poisonous, so if you touch one it’s harmful (problematic for divers)- There are efforts to round up the Lion Fish Clicker Question: How did the brown tree snake arrive on Guam? Pet trade Stowaway Introduced to hunt rats- Most people said C; however that is not the correct answer.- The most likely introduction was that they were stowaways. Guam has a military base and tree snakes may have come on ships or planes. It only takes a few snakes to establish a breeding population. Brown Tree Snake Impacts of Brown Tree Snake- 10 of 12 forest bird species extinct- 50% of lizard species on island extinct- Indirect negative impact on plants- Fruit bats are great pollinators, but the snakes are eating them too In this case, we’ve moved a species into an environment in which it has become really well established and is impacting the whole ecosystem Not every species we move is going to become an invasive species: Just ones with favorable conditions will We are moving things all over the place at a really scary rate. Species can migrate naturally, but the human impact is moving them scary fast: Human impact has escalated the rate, distance and frequency of these introductions Pollution Smog and air pollution is problematic in a lot of cities. It has an effect on the people there as well as an impact on the environment; we see isolated cases where there are impacts on biogeochemical cycles Garbage collects
