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. -

Individuals moving to new areas usually 18 confront a different set of biotic and abiotic variables, and most dispersed individuals do not 19 survive. However, if they are capable of surviving and adapting to the new conditions, they may 20 establish self-sufficient populations, colonise the new areas, and even spread into nearby 21 locations (Mack et al. 2000). In doing so, they will produce ecological transformations in the 22 new areas, which may lead to changes in other species’ populations and communities, speciation 23 and the formation of new ecosystems (Wilson et al. 2009). 24 25 Human extra-range dispersals since the Pleistocene have produced important distribution 26 changes across species of all taxonomic groups. Along our prehistory and history, we have aided 27 other species’ extra-range dispersals either by deliberate translocations or by ecological 28 facilitation due to habitat changes or modification of ecological relationships (Boivin et al. 29 2016). -
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). -

(Diptera: Muscidae): an Invasive Avian Parasite on the Galápagos Islands Lauren K
Chapter Taxonomic Shifts in Philornis Larval Behaviour and Rapid Changes in Philornis downsi Dodge & Aitken (Diptera: Muscidae): An Invasive Avian Parasite on the Galápagos Islands Lauren K. Common, Rachael Y. Dudaniec, Diane Colombelli-Négrel and Sonia Kleindorfer Abstract The parasitic larvae of Philornis downsi Dodge & Aitken (Diptera: Muscidae) were first discovered in Darwin’s finch nests on the Galápagos Islands in 1997. Larvae of P. downsi consume the blood and tissue of developing birds, caus- ing high in-nest mortality in their Galápagos hosts. The fly has been spreading across the archipelago and is considered the biggest threat to the survival of Galápagos land birds. Here, we review (1) Philornis systematics and taxonomy, (2) discuss shifts in feeding habits across Philornis species comparing basal to more recently evolved groups, (3) report on differences in the ontogeny of wild and captive P. downsi larvae, (4) describe what is known about adult P. downsi behaviour, and (5) discuss changes in P. downsi behaviour since its discovery on the Galápagos Islands. From 1997 to 2010, P. downsi larvae have been rarely detected in Darwin’s finch nests with eggs. Since 2012, P. downsi larvae have regularly been found in the nests of incubating Darwin’s finches. Exploring P. downsi ontogeny and behaviour in the larger context of taxonomic relationships provides clues about the breadth of behavioural flexibility that may facilitate successful colonisation. Keywords: Protocalliphora, Passeromyia, Philornis, nest larvae, hematophagous, subcutaneous, Darwin’s finches, Passeriformes 1. Introduction Three genera of flies within the order Diptera have larvae that parasitise avian hosts: Protocalliphora Hough (Calliphoridae), as well as Passeromyia Rodhain & Villeneuve (Muscidae) and Philornis Meinert (Muscidae). -

The marine iguana is also extremely unusual, since it is the only iguana adapted to life in the sea. Galapagos hermit crabs. Reptiles While most of the world finds that mammals are the predominant land animals, the Galapagos Islands' land animals are dominated by reptiles. The vast majority of such rafts would have sunk well before they ever reached Galapagos, but it would have only taken a handful of successful rafts to wash ashore to explain the present reptile diversity in Galapagos. Galapagos Sea Lion Photo by Reinier Munguia These are one of the more common animals that can be found on the islands, either splashing and diving through the ocean or basking on sandy beach shores. With bodies up to 45 inches long and a massive wingspan, they can usually be seen soaring aloft often on wind currents created by boats , never touching the water. On the other hand, there are many mammal species, mostly sea mammals such as whales , dolphins and sea lions. At night they come out to hunt a variety of insects, including moths, flies, true bugs, beetles and cicadas. Talk with an expert Ask a Question. They have an endangered species status, as there are less than 2, of them on the islands. Explained briefly, the concept of the evolution of species is based on a number of characteristics of survival and reproduction. Cetaceans of Galapagos. -

Species List November 5 – 12, 2017 | Compiled by Bob Meinke
Journey to the Galápagos | Species List November 5 – 12, 2017 | Compiled by Bob Meinke Hosts Carol Simon & Howard Topoff, with National Park Naturalists & 18 participants 316 Total Bird Species (Galápagos & Mainland Ecuador Combined) Bird List — Galápagos: 57 Species Seen, with 21 Species-level Endemics; (E) = endemic Anatidae: Ducks, Geese, and Swans (1) White-cheeked Pintail (Anas bahamensis) The only duck seen in the Galápagos, several were observed by most of the group on Santa Cruz Is. (in saline lagoons just in from the sandy beach at Las Bachas), as well as in the Santa Cruz highlands on a pond at the tortoise farm (Poza El Chato) we visited. Phoenicopteridae: Flamingos (1) American Flamingo (Phoenicopterus ruber) Six beautiful, bright pink birds were wading and filter feeding in the Las Bachas lagoons on Santa Cruz Is.—once considered conspecific with the Greater Flamingo (P. roseus) of the Old World, recent work suggests the “Galápagos Flamingo” may merit recognition as an endemic subspecies (i.e., P. ruber ssp. glyphorhynchus). Spheniscidae: Penguins (1) Galápagos Penguin (E) (Spheniscus mendiculus) Adults and juveniles (estimated 20 to 30) were observed up close on two days, first on shoreline rocks on Fernandina Is., then during our mangrove estuary excursion at Elizabeth Bay and near Tagus Cove (both on Isabela Is.). Procellariidae: Petrels and Shearwaters (1) Galápagos Shearwater (E breeder) (Puffinus subalaris) Frequently observed, mainly from the ship, this common seabird was present most days flying singly or in small groups over open water, especially near cliffs. Hydrobatidae: Storm-petrels (3) Elliot’s Storm-Petrel (Oceanites gracilis) The most common of the three readily observed shearwaters in the Galápagos, we saw many individuals daily—Elliot’s is endemic to the Humboldt Current (also known as White-vented Storm-Petrel).
