Cross-Temporal Analysis of Genetic Diversity in the Endangered Medium Tree Finch (Camarhynchus Pauper) and Closely Related Darwin’S Finches
Cross-Temporal Analysis of Genetic Diversity in the Endangered Medium Tree Finch (Camarhynchus pauper) and Closely Related Darwin’s Finches By Colleen Metzger B.S., Juniata College, 2009 A thesis submitted to the Graduate School of the University of Cincinnati Department of Biological Sciences In partial fulfillment of the requirements For the degree of Master of Science Committee Chair: Kenneth Petren, Ph.D. November 2012 Abstract Natural history collections can provide a direct view of past genotypes, which allows greater insight into evolutionary processes that are relevant for conservation and management. However, few studies have used broad surveys of multilocus genotypes from the past to address the wide range of processes that can affect conservation planning of a species today. Therefore, we assessed the history and status of the critically endangered medium tree finch, Camarhynchus pauper, an endemic finch of the Galápagos Islands. Using ancient DNA techniques, we quantified cross-temporal genetic change for 16 microsatellite loci in this species and its relatives. We tested the hypothesis that C. pauper has undergone a recent reduction in population size and loss of genetic diversity, and evaluated the hypothesis that C. pauper is genetically distinct from its two closest relatives, C. parvulus and C. psittacula. We assessed whether decline in C. pauper has led to increased hybridization with other species and evaluated a long-standing hypothesis of its origin from C. psittacula on another island using genetic distances, assignment tests, and migration analyses. Genetic diversity declined significantly in C. pauper over time, and several other tree finch populations showed similar losses of genetic diversity. -

Day 1 Monday 29th January UK to Quito People arrived in Quito via Amsterdam with KLM or via Madrid with Iberia, while Tony came separately from the USA. Everyone was met at the airport and taken to the Hotel Vieja Cuba; those who were awake enough went out to eat before a good night’s rest. Day 2 Tuesday 30th January Quito. Weather: Hot and mostly sunny. The early risers saw the first few birds of the trip outside the hotel: Rufous- collared Sparrow, Great Thrush and Eared Doves. After breakfast, an excellent guide took us on a bus and walking tour of Quito’s old town. This started with the Basilica del Voto Nacional, where everyone marvelled at the “grotesques” of native Ecuadorian animals such as frigatebirds, iguanas and tortoises. -
FIELD GUIDES BIRDING TOURS: Galapagos: an Intimate Look At
Field Guides Tour Report Galapagos: An Intimate Look at Darwin's Islands II 2014 Jul 5, 2014 to Jul 15, 2014 Megan Edwards Crewe with Peter Freire For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. For those interested in natural history, the Galapagos Islands are a wonderland. Every island is a revelation. The animals -- though wild and unfettered -- are so trusting as to seem tame. Our week's cruise brought us within arm's length of Galapagos Tortoises the size of coffee tables and whip-fast lava lizards. Albatrosses snoozed in the middle of paths. Mockingbirds investigated bare toes. Boobies stomped their way through our group. "Darwin's Finches" circled as if planning to land atop heads or arms or camera lenses. And everywhere, we could settle in for extended studies of plants or birds or insects or herps or fish, secure in the knowledge that they just wouldn't care that we were there. As you might expect in such a naturalist's paradise, there were many, many highlights. Waved Albatrosses called and bowed and clattered their beaks together, or brooded small chicks (which look surprisingly poodle- The Swallow-tailed Gull is surely one of the world's most handsome seabirds. (Photo by guide Megan like, thanks to their curly feathers). Blue-footed Edwards Crewe) Boobies whistled and grunted and solemnly displayed their extraordinary feet to each other. Well-camouflaged Short-eared Owls lurked among a whirling mass of Wedge-rumped Storm-Petrels, waiting for an opportunity -- and a one-eyed hunter gobbled its hapless prey nearly at our feet. -

Galapagos Islands Fact Sheet Galapagos Islands Fact Sheet
GALAPAGOS ISLANDS FACT SHEET GALAPAGOS ISLANDS FACT SHEET INTRODUCTION The Galapagos Islands are located west of Ecuador and are renowned for being the home to a vast array of fascinating species of wildlife, including lava lizards, the giant tortoise as well as red and blue-footed boobies. They are one of the world’s foremost destinations for wildlife viewing, many of the plant and animal species being found nowhere else in the world. Located at the confluence of three ocean currents and surrounded by a marine reserve, the islands abound with marine species. The Galapagos Islands, of which there are 19 main islands, are an archipelago of volcanic islands in the Pacific Ocean. They lay either side of the Equator and 1,000km west of the South American continent and mainland Ecuador of which they are a part. The islands were formed as a result of processes caused by volcanic and seismic activity. These processes along with the isolation of the islands resulted in the development of unusual animal life. Charles Darwin’s visit to the islands in 1835 was the inspiration for his theory of evolution by natural selection. The largest island Isabela, measures 5,827 square kilometres and accounts for nearly three quarters of the total land area of the Galapagos. Volcan Wolf on Isabela is the highest point of the Galapagos at 1,707m above sea level. GALAPAGOS ISLANDS FACT SHEET CLIMATE The Galapagos Islands have a subtropical and dry climate with comfortable temperatures year-round. The warmest months are usually from December to June (high season) and this is the recommended time to visit. -
Can Darwin's Finches and Their Native Ectoparasites Survive the Control of Th
Insect Conservation and Diversity (2017) 10, 193–199 doi: 10.1111/icad.12219 FORUM & POLICY Coextinction dilemma in the Galapagos Islands: Can Darwin’s finches and their native ectoparasites survive the control of the introduced fly Philornis downsi? 1 2 MARIANA BULGARELLA and RICARDO L. PALMA 1School of Biological Sciences, Victoria University of Wellington, Wellington, New Zealand and 2Museum of New Zealand Te Papa Tongarewa, Wellington, New Zealand Abstract. 1. The survival of parasites is threatened directly by environmental alter- ation and indirectly by all the threats acting upon their hosts, facing coextinction. 2. The fate of Darwin’s finches and their native ectoparasites in the Galapagos Islands is uncertain because of an introduced avian parasitic fly, Philornis downsi, which could potentially drive them to extinction. 3. We documented all known native ectoparasites of Darwin’s finches. Thir- teen species have been found: nine feather mites, three feather lice and one nest mite. No ticks or fleas have been recorded from them yet. 4. Management options being considered to control P. downsi include the use of the insecticide permethrin in bird nests which would not only kill the invasive fly larvae but the birds’ native ectoparasites too. 5. Parasites should be targeted for conservation in a manner equal to that of their hosts. We recommend steps to consider if permethrin-treated cotton sta- tions are to be deployed in the Galapagos archipelago to manage P. downsi. Key words. Chewing lice, coextinction, Darwin’s finches, dilemma, ectoparasites, feather mites, Galapagos Islands, permethrin, Philornis downsi. Introduction species have closely associated species which are also endangered (Dunn et al., 2009). -

Ability of crassulacean acid metabolism plants to overcome interacting stresses in tropical environments. AoB PLANTS 2010: plq005, doi:10.1093/aobpla/plq005 Abstract Background and Single stressors such as scarcity of waterand extreme temperatures dominate the struggle for life aims in severely dry desert ecosystems orcold polar regions and at high elevations. In contrast, stress in the tropics typically arises from a dynamic network of interacting stressors, such as availability of water, CO2, light and nutrients, temperature and salinity. This requires more plastic spatio- temporal responsiveness and versatility in the acquisition and defence of ecological niches. Crassulacean acid The mode of photosynthesis of crassulacean acid metabolism (CAM) is described and its flex- metabolism ible expression endows plants with powerful strategies for both acclimation and adaptation. Thus, CAM plants are able to inhabit many diverse habitats in the tropics and are not, as com- monly thought, successful predominantly in dry, high-insolation habitats. Tropical CAM Typical tropical CAM habitats or ecosystems include exposed lava fields, rock outcrops of insel- habitats bergs, salinas, savannas, restingas, high-altitude pa´ramos, dry forests and moist forests. Morphotypical and Morphotypical and physiotypical plasticity of CAM phenotypes allow a wide ecophysiological physiotypical amplitude of niche occupation in the tropics.
