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. -

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. -

Yuval: [email protected] Abstract. Philornis downsi (Diptera: Muscidae) is a nest parasitic fly that has invaded the Galapagos archipelago and exerts an onerous burden on populations of endemic land birds. As part of an ongoing effort to develop tools for the integrated management of this fly, our objective was to determine its long and short-range responses to bacterial and yeast cues associated with adult P. downsi. We hypothesized that the bacterial and yeast communities will elicit attraction at distance through volatiles, and appetitive responses upon contact. Accordingly, we amplified bacteria from guts of adult field-caught individuals and bird feces, and yeasts from fermenting papaya juice (a known attractant of P. downsi), on selective growth media, and assayed the response of flies to these microbes or their exudates. -
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.

Both Philornis downsi natural fluctuations in environmental conditions and habitat management measures can temporarily cause Darwin's finches adverse environmental effects. In this study, we investigated the interaction between the invasive parasitic fly Invasive species Philornis downsi, control of invasive plants and precipitation on the breeding success of Darwin's finches. Parasitism Introduced plant species have invaded a unique forest on the Galapagos island of Santa Cruz, which is a key Arthropod biomass habitat for Darwin's finches. The Galapagos National Park Directorate applies manual control and herbicides to Weed management combat this invasion. We hypothesized that these measures led to a reduction in the arthropod food supply during chick rearing, which in turn caused mortality in chicks that were already weakened by parasitism. We compared food availability in three study sites of varying degrees of weed management. To assess the interaction of parasitism and weed management, we experimentally reduced P. -

Being masters of chemical reactions, they regulate the recycling of all major chemicals relevant to life; manage energy sources and the production of fuels; determine the aerobic conditions of our atmos- phere and influence our climate; are the catalytic fac- tors of soil fertility, thus affecting agricultural produc- tion; and have also been of paramount importance for the health of ecosystems and of all living organisms including humans. Last, but not least, they have been the driving force of the on-going “biotechnological revolution”, which promises to produce more and healthier food, drugs and “green” fuels. Because of all their unique metabolic properties, microbes have been driving the evolution of life on earth, either by being free-living or by establishing symbiotic associations with diverse organisms including insects. Insects are the most abundant and species-rich animal group on earth, occupying most available ecological niches. Conservative estimates suggest that about 85% of all described animal species are insects; estimates range between 2-30 million insect species and about 10 18 quintillion (10 ) individual insects being alive at any given time (http://www.si.edu/Encyclopedia_SI/nmnh/ The tsetse fly Glossina morsitans and its associated symbiotic bac- buginfo/bugnos.htm). -
