21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -

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. -

ORNITHOLOGISCHER ANZEIGER Zeitschrift bayerischer und baden-württembergischer Ornithologen Band 50 – Heft 1 Juli 2011 Ornithol. Anz., 50: 1–25 Wühlmäuse (Arvicolinae) als bevorzugte Beute des Uhus Bubo bubo während der Jungenaufzucht in Bayern Andreas Schweiger und Ludwig Lipp Voles (Arvicolinae) as preferred prey of Bavarian Eagle Owls Bubo bubo (L.) during the nestling period. A sufficient choice of prey with adequate size is quoted in numerous surveys about feeding ecolo- gy of the Eurasian Eagle Owl as one of the most important factors allowing the survival of a suc- cessful population. On the other hand a high proportion of small animals in the diet is regarded as an indicator of malnutrition, and a threat to the successful maintenance of the greatest European Owl. Examination of prey items, mainly from the breeding season, over 33 years (1976-2008), in three Bavarian subpopulations of the Eagle Owl reveals a very different and conflicting pattern. Uni- and multivariate statistical evaluation were based on a quantification of food diversity, favoured size of prey and percentage proportion of particular prey items in the diet of fledging Eagle Owls. The results from this survey show a clear preference of Bavarian Eagle Owls for voles (Arvicolinae). The diversity of prey actually declines with increasing proportion of voles. An increasing amount of major prey like waterfowl leads to a greater prey diversity. Even so, comparison between Bavarian sub-populations of Eagle Owl shows both considerable regional differences and clear temporal dif- ferences and changes in prey spectrum, caused e.g. by changes in landuse. In general Bavarian Eagle Owls take small mammals in large quantities while rearing their young. -

Conservation Implications of Illegal Bird Trade and Disease
CONSERVATION IMPLICATIONS OF ILLEGAL BIRD TRADE AND DISEASE RISK IN PERU A Dissertation by ELIZABETH FRANCES DAUT Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Donald J. Brightsmith Co-Chair of Committee, Markus J. Peterson Committee Members, Renata Ivanek-Miojevic Christian Brannstrom Head of Department, Roger Smith III May 2015 Major Subject: Veterinary Microbiology Copyright 2015 Elizabeth Frances Daut ABSTRACT Trade in wild-caught animals as pets is a global conservation and animal-welfare concern. Illegal and poorly-regulated legal wildlife trade can threaten biodiversity, spread infectious diseases, and result in considerable animal suffering and mortality. I used illegal wildlife trade in Peru, specifically native bird trade, as a case study to explore important aspects and consequences of the trade for domestic markets. With data collected from a five-year market survey and governmental seizure records, I applied a statistical modeling approach to investigate the influence of Peru’s legal export quota system on the country’s illegal domestic bird trade. I used an infectious-disease mathematical modeling approach to analyze how illegal harvest influenced disease dynamics in a wild parrot population. Finally, I used qualitative research methods to investigate the role of non-governmental organizations (NGOs) and their members’ philosophical perspectives toward wildlife in combating illegal trade. I found that Peru had a thriving illegal trade in native birds (mostly parrots) for domestic consumers; 150 species were recorded in markets and/or seizures with over 35,250 individuals offered for sale (2007–2011). -
Lüttge-2010-Ability of Crassulacean Acid Metabolism Plants to Overcome
AoB PLANTS http://aobplants.oxfordjournals.org/ Open access – Review Ability of crassulacean acid metabolism plants to overcome interacting stresses in tropical environments Ulrich Lu¨ttge* Institute of Botany, Technical University of Darmstadt, Schnittspahnstrasse 3-5, D-64287 Darmstadt, Germany Received: 26 January 2010; Returned for revision: 16 March 2010; Accepted: 10 May 2010; Published: 13 May 2010 Citation details:Lu¨ttge U. 2010. 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. -
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). -
The Systematics and Genetics of Tomatoes on the Galápagos Islands (Solanum, Solanaceae)
The systematics and genetics of tomatoes on the Galápagos Islands (Solanum, Solanaceae) By Sarah Catherine Darwin A thesis submitted for the degree of Doctor of Philosophy at University College London August 2009 Department of Genetics, Evolution and Environment University College London 1 Declaration I, Sarah Darwin confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Chapter 2 is a reprint from a paper on the taxonomy of the tomatoes of the Galápagos Islands published in Systematics and Biodiversity in 2003. This was a collaborative project, and the authors were Sarah Darwin, Sandra Knapp and Iris Peralta. I was the lead author as this was part of my thesis work, and I carried out most of the work towards the paper. Below I list the contributions of each author for Chapter 2. Morphological analysis I undertook the analysis of the herbarium specimens, with particular guidance from Sandy Knapp and Iris Peralta for the S. lycopersicum and S. pimpinellifolium collected from the mainland of South America. Morphometrics Morphological characters were selected by all of us based on my experience from fieldwork, Dr Peralta’s experience from greenhouse grown accessions and Dr Knapp’s experience from herbarium specimens. I undertook the measurement of the living plants and herbarium specimens with the assistance/guidance of Drs Peralta and Knapp Statistics I and Dr Peralta undertook the PCA, with advice from Drs Claudio Galmarini and Clive Moncrieff. Taxonomic treatment Dr Knapp and Dr Norman Robson wrote the Latin for the taxonomic treatment.
