Geography 316: Biogeography Update The Biogeography of the (Dendraster excentricus) by Karen Vitulano, student in Geography 316 Kingdom: Animalia Phylum: Echinodermata Class: Echinoidea Order: Clypeasteroida Family: Dendrasteridae Genus: Dendraster Species: Dendraster excentricus Description of Species: The Sand Dollar Dendraster excentricus is a marine invertebrate that lives in the sandy bottoms of sheltered bays and open coastal areas. They form dense beds in the low intertidal and subtidal zones of sheltered bays, and in the subtidal zone just beyond the break zone of coastal areas. The body of Dendraster excentricus A flower-like pattern is seen on the aboral side of the body composed of pore pairs where specialized tube feet perform gas exchange. At the center is the madreporite - a perforated platelike structure that forms the intake for their water-vascular system, and adjacent to this on the interambulacra, the genital pores. Radiating out from the genital pores are the five flower petals, which represents the ambulacral radii. The flower pattern in this species is off-center, thus the meaning of the name excentricus Natural History: Feeding Dendraster excentricus is considered a suspension feeder and feeds on suspended organic particulate matter in the water currents. Various specialized spines, tube feet, mucus-secreting glands and the pedicellariae – small pincher-like organs with moveable jaws, are involved in feeding (Jangoux and Lawrence 1983). The spines on the aboral side are club-shaped and covered with cilia. When small organic particles and organisms flow onto this surface, little eddies are created and particles become trapped by mucus secreted on the spines. They are directed by these club-shaped spines and cilia to the margins and around to the oral side to the food grooves, where they move in mucus streams that lead to the mouth in the center (Morris 1980).

Exercises Lecture notes Darwin's evidence for evolution: Biogeographic distributions I. Three important principles : How do these principles support descent with modification? A. Environment cannot account for either similarity or dissimilarity, since similar environments can harbor entirely different species groups B. "Affinity" (=similarity) of groups on the same continent (or sea) is closer than between continents (or seas) C. Geographical barriers usually divide these different groups, and there is a correlation between degree of difference and rate of migration or ability to disperse across the barriers II. Disjunct locations for the same extant species: Good evidence for creation? (Evolution proposes Single Centers for the origins of species, so Discontinuous Distributions need to be explained) A. Means of dispersal must be proposed 1. Changes in climate or geology must have affected migration (i.e., by first allowing migration and then preventing migration)

Source: Haaker et al. 1986. Description of Species: Abalone are marine mollusks, they have a soft body surrounded by a mantle, an anterior head, and a large, muscular foot (see Figure 1). Abalone shells are rounded or oval with a large dome towards one end and a row of respiratory pores. The muscular foot has strong suction power enabling the abalone to cling to rocky surfaces. An epipodium is a sensory structure and extension of the foot that has tentacles, it circles the foot and extends outside the edge of the shell (see Figure 2). The red abalone can reach sizes upwards of a foot but commonly sizes range from 6 to 8 inches. A red abalone can be identified in the field usually by the brick red surface of its shell, although color can be masked at times by encrusted organisms. Red abalones generally have 3 to 4 moderately elevated pores on the surface of its shell. that are moderately elevated. The epipodium, foot and tentacles are all black. Figure 2. Abalone anatomy

One of the fist people to draw attention to them was a man named Bates in 1863 what follows is his notes " Wherever they pass they through the rest of the animal world in a state of alarm. They steam along the ground and climb any lower trees searching every leaf to its apex. When the booty is plentiful they concentrate all of their forces upon it, the dense phalanx of shining and quickly moving bodies swarm. As it spreads over the surface they look like a flood of dark red liquid. They soon penetrate every part f the confused heap, and then, gathering together again in marching order, onward they move. They tear their victims in pieces for facility of carriage. The margins of the phalanx spread out at times like a cloud of skirmishers from the flanks of an army". The designation "army ants" although an analogy fits well, these creatures given to carrying out attacks en masse. Habitat: The army ants as figure 2 shows have a worldwide distribution, with representatives in each hemisphere roughly between 45 degrees north and 45 degrees south. They are found in most tropical and subtropical parts of the world with some notable exceptions. In the New World Chile, the volcanic islands of the Caribbean, mountain heights, and certain extensive desert and swampy areas. In the Old World the Sahara, Afghanistan, and desert areas, as well as the afore mentioned mountainous and swampy regions (Schneirla 1971).

The workers are females and cannot reproduce eggs that become other workers but can make eggs that produce males (Weber 1972). The role of the female in a leaf cutter ant colony is very important, queens are essential and are part of the female caste structure. Males on the other hand do not work in or out of the colony and are winged to inseminate the virgin queens (Weber 1972). The worker ants are covered with small spines and have long legs and appear reddish brown in color (Weber 1972). These tiny workers have large mandibles with fine sharp teeth (Weber 1972). Two antennae appear at the face of the worker and are waved around as they move (Weber 1972). The females or queens have larger eyes with and are much coarser than the other castes. Queens and females are significantly larger than males and their wings extend past their rear (Weber 1972). Males are darker than workers and queens and are usually smaller (Weber 1972). The wings are similar to the females, extending past the body (Weber 1972).

The Biodiversity of Richmond, British Columbia What is Biogeography? (under construction) Biogeography is the science that attempts to document and understand spatial patterns of biodiversity. It is the study of distributions of organisms, both past and present, and of related patterns of variation over the earth in the numbers and kinds of living things. Where do species occur, why do they occur there, and where are the greatest concentrations? The implications of these questions for global health are enormous. It is the species on the planet that feed us, clothe us, medicate us, and shelter us. They produce oxygen, filter water and provide fuel. In times of climate change, we need an immense variety of species in order offset the resulting environmental change. In biogeography we examine several concepts. These include species distribution and abundance (why species occur where they do), population health and viability, endemism, the biogeography of islands, rarity, equilibium theory, speciation and species hotspots. We examine what makes one species common or even abundant, and what makes another species rare. The causes of rarity and abundance have always been of ecological interest, and have been studied by such eminent ecologists as Mayr, Simberloff, Wilson, Keddy, and others. Keddy's work is of particular interest to us living along the shores of the Fraser River. He has studied wetland ecology, including shoreline species ecology, competition in plants, assembly rules and invasive species.
