Jenna Krause BIO 203 Outdoor Diversity Scavenger Hunt This assignment will help you start to get familiar with some of the groups and group names we will be studying this semester and to recognize that this diversity is all around us even on campus Use the directions below to make your way around campus There are orange ribbons marking each of the locations In addition to answering each question put the letter for that question on the appropriate place in the phylogenetic tree on the last page of this assignment for any taxa written in bold type For example for question A find Echinodermata on the tree figure and put an A next to the name we did this first one for you Then answer the question in the space provided Location 1 Head out the front doors of Carl Wimberly Hall facing Cowley To your left there are some large limestone rocks used as part of the landscaping A Notice the long skinny fossils in the rock they are crinoids which are members of the Echinodermata relatives of sea urchins and starfish Rocks containing these fossils are found all over Wisconsin Take a photo of the fossils and insert it in this document or attach as a separate file Based on the habitat their relatives live in what would you guess this tells you about conditions in Wisconsin when the fossils were formed inWarm Shallowwaterenvironmentsweremust covered in water or much more water coverage than today B Later in spring there will be flowering plants Anthophyta surrounding the rocks that are flooded with pollinators like bees flies ants etc which belong to the Arthropoda What type of ecological interaction is taking place between the pollinators and plants it is a mutualistic relationship the pollinators are receiving food whilethe plants are receiving sexual reproductions from receiving polinfrom other plants Location 2 Head towards Prairie Springs Science Center On the north side of the building there is a row of shrubs that have serrate leaves the edges have little teeth like a saw blade and big dark berries that look kind of like blueberries These are black chokeberries which are too bitter to be good to eat C Black chokeberries like most the plants that we do eat are members of the Phylum Anthophyta the flowering plants For all of these plants fruit develops from the mature ovary of the flower that contains the seeds Take a photo of one of the black chokeberry plants and insert it in this document or attach as a separate file Not all fruits are sweet but all contain seeds Go to the Dining at UWL menu https dineoncampus com uwlacrosse whats on the menu and select Main Dining Room from the dropdown menu of dining locations Under the Lunch or Dinner menus find three examples of fruits from the menu Mandarin oranges 3 Watermelon 1 pineapple 2 Vegetables are plant parts that are not fruits From the same menu give one example each of an edible vegetable that is a 1 Stem celery carrot 2 Root 3 Leaf lettuce Location 3 Head back toward the front of the Murphy Library Near the southeast corner of the library there are two large trees as you approach the clock tower D The evergreen tree belongs to the plant group known as the Gymnosperms which produce seeds in cones Seeds contain young plants called embryos which grow from a zygote formed from the fusion of a sperm and an egg Based on that information which type of reproduction are the cones you see involved in sexual or asexual sexual reproduction E There is a small tree next to the two evergreen trees Take a look this tree has lichens growing on its trunk yellow green color You get to put an E in two places on your phylogenetic tree because lichens are a dual organism they are formed by the symbiosis of a cyanobacterium Domain Bacteria or green algae Major Clade Archaeplastida and a fungus usually a member of the Ascomycota There is more limestone right here too Look closely at the lichens some may be producing spore making structures that look like tiny black cups Take a photo of the tree trunk showing at least one of the types of lichen and insert it into this document or attach as a separate file How many different types of lichen do you think are growing here What traits did you use to distinguish the different lichen types I would say there is several different types of lichen growing here there were areas of the tree that were different colors ranging from white to green and some were more compact lichens or more spread out accross the tree some were also protruding fromthe tree while others were flat accross the tree F Go towards the stadium and examine the eagle statue on top of the Veteran s Memorial Stadium Eagles are members of Phylum Chordata just like us and eels and frogs Birds fish and amphibians share the trait of reproducing primarily through egg laying which type of mammal also lays eggs this way platypus Location 4 Walk west to Centennial Hall and go inside to the large atrium Examine the large panel hanging to your left as you face the main doors opening towards Wing You will notice that this is an artist s rendition of the La Crosse area depicting the Mississippi River and the surrounding terrestrial environments G If you look closely at the panel you should be able to make out a few embedded mussel shells members of Phylum Mollusca What type of selection pressures do you think resulted in the evolution of shells in the Mollusca I would say thatthe Mollusca evolved due to predatory pressures antheneeds hiddenmoufgedn as of resources Location 5 Head out the nearest doors towards the courtyard H Check out the big planter to the LEFT of the door as you exit The tall green organisms here are commonly called horsetail and are members of the Pteridophyta Look for leaves on the plant and then state which plant organ stems roots or leaves appears to be most important for photosynthesis for these organisms leaves chlorophyll presence within their leaves I On a pillar in front of the doors into Centennial was a plaque in memory of a former Biology professor named Dan Sutherland He worked on parasitic trematodes members of the Phylum Platyhelminthes which have been shown to contribute to amphibian deformities What is one trait that the eukaryotic Platyhelminthes share with you theycontainsevalorgansthey also have bilateraise J As you walk south out of the courtyard notice the small trees to your left These are oaks which are flowering plants in Phylum Anthophyta All members of this phylum produce seeds inside a fruiting body What is the more
