  • Section IV – Guideline for the Texas Priority Species List
    Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

Of particular note have been the contributions of members of the Core Team who devoted large amounts of time, sometimes under duress, toward the completion of this report: Jorge Brenner, Bill Carr, Amalie Couvillion, Troy Ettel, Steve Gilbert, Ray Johnson, Richard Martin, Latimore Smith, and David Wolfe. Special thanks go to Amalie Couvillon who kept momentum going when no one else would or could. In addition, Steve Gilbert went the “extra yard” regarding data management and GIS analysis with committed and positive spirit.

  • THE EVOLUTION of CORAL SNAKE MIMICRY Christopher Kemal Akcali
    THE EVOLUTION OF CORAL SNAKE MIMICRY Christopher Kemal Akcali A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Biology. Chapel Hill 2019 Approved by: David W. Pfennig Karin S. Pfennig Bryan L. Stuart Christopher H. Martin David W. Kikuchi © 2019 Christopher Kemal Akcali ALL RIGHTS RESERVED ii ABSTRACT Christopher Kemal Akcali: The evolution of coral snake mimicry (Under the direction of David Pfennig) Batesian mimicry—when individuals of a palatable species (the “mimic”) gain the selective advantage of reduced predation because they resemble a toxic species (the “model”) that predators avoid—is a classic example of the power of natural selection to drive adaptation. Although evolutionary biologists have long known about Batesian mimicry, many aspects of its evolution remain unclear. My first chapter evaluated whether—and in which direction—Batesian mimicry has evolved in a natural population of mimics following extirpation of their model. Specifically, I examined whether the precision of coral snake mimicry has evolved among scarlet kingsnakes (Lampropeltis elapsoides ) from a region where their model, the eastern coral snake ( Micrurus fulvius ), recently (1960) went locally extinct. I found that L. elapsoides has evolved more precise mimicry. These results suggest that selection imposed on mimics by predators has generated an “evolutionary momentum” towards precise mimicry after models became extirpated. My second chapter examined the causes of geographic variation in the resemblance of Batesian mimics to their models. I characterized geographic variation in mimetic precision among four Batesian mimics of coral snakes to test hypotheses for geographic variation in mimicry.

Kemp’s Ridley turtles are believed to remember the beach where they were hatched. Coyotes are among the animals known to inhabit the Padre Island National Seashore. Snapping turtles are tracked and monitored at PAIS. ON THE COVER Located along the south Texas coast, Padre Island National Seashore protects the longest undeveloped stretch of barrier islands in the world. Here, you can enjoy 70 miles of sandy beaches, wind-carved dunes, vast grasslands, fragile tidal flats, and warm, nearshore waters.

Swamps & bogs are common. Long leaf, short leaf and loblolly pines are dominant species. Some flowers are lady slipper, iris, meadowbeauty, beebalm, lyre-leaf sage, and spider lily. Tree frogs, fox, squirrel, salamanders are common animals. Birds: of forests include warblers, thrushes, woodpeckers and chickadees. Red shouldered hawks roam the riparian areas of the rivers and streams. This region gets 36 to 50 inches of rain per year which gives this region the highest rainfall per year. The geography of the region is hilly to gently rolling plains. Endangered Species: Red Cockaded Woodpecker Endangered Species: Red Wolf Endangered Species: Texas Trailing Phlox Endangered Species: White Bladderpod Endangered Species: Louisiana Black Bear Threatened Species (State): Bachman’s Sparrow Threatened Species (State): Swallow-tailed Kite Threatened Species (State): Rafineseque’s Big Eared Bat Threatened Species (State): Northern Scarlet Snake Threatened Species (State): Timber Canebrake Rattlesnake Threatened Species (State): Alligator Snapping Turtle Gulf Coast Prairies and Marshes (2): This region is a narrow band of 13 million acres of nearly flat land bordering the Gulf of Mexico. It is a region of rich sandy or clay loam soils and once was covered with tall grass prairies. Marshes and woodlands dot the prairies. Barrier islands protect the mainland prairie region. Some coastal grasses are seascoast bluestem, Eastern gama grass, little bluestem, gulf muhly, bushy bluestem and cordgrass.
