SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips. -

The recent discovery of 2 isolated small populations from the known distribution for this taxon makes necessary an evaluation to determine their specific taxonomical identities (herein designated as G. cf. eremica). Thirty-three morphometric and 6 meristic characters were evaluated in 219 specimens of several populations of the genus Gila in Sonora, including all the known populations of G. -
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. -
Drought, Dispersal, and Community Dynamics in Arid-Land Streams
AN ABSTRACT OF THE DISSERTATION OF Michael T. Bogan for the degree of Doctor of Philosophy in Zoology presented on July 10, 2012. Title: Drought, Dispersal, and Community Dynamics in Arid-land Streams Abstract approved: _____________________________________ David A. Lytle Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In stream ecosystems, the natural flow regime (including the timing, magnitude, and duration of high and low flow events) is widely recognized as a primary regulator of local diversity and community composition. This is especially true in arid- land streams, where low- and zero-flow events can occur frequently and for extended periods of time (months to years). Additionally, wetted habitat patches in arid-land stream networks are often fragmented within and among stream networks. Thus dispersal between isolated aquatic patches may also play a large role in regulating local communities. In my dissertation, I explored the roles that drought, dispersal, and local habitat factors play in structuring arid-land stream communities. I examined the impact of flow permanence and seasonal variation in flow and other abiotic factors on aquatic communities at both fine spatial scales over a long time period (8 years; Chapter 2) and at a broad spatial scale over a shorter time period (1-2 years; Chapter 4). Additionally, I quantified aquatic invertebrate aerial dispersal over moderate spatial scales (≤ 0.5 km) by conducting a colonization experiment using artificial stream pools placed along and inland from two arid-land streams (Chapter 4). -

South East Brazil, 18Th – 27Th January 2018, by Martin Wootton
South East Brazil 18th – 27th January 2018 Grey-winged Cotinga (AF), Pico da Caledonia – rare, range-restricted, difficult to see, Bird of the Trip Introduction This report covers a short trip to South East Brazil staying at Itororó Eco-lodge managed & owned by Rainer Dungs. Andy Foster of Serra Dos Tucanos guided the small group. Itinerary Thursday 18th January • Nightmare of a travel day with the flight leaving Manchester 30 mins late and then only able to land in Amsterdam at the second attempt due to high winds. Quick sprint (stagger!) across Schiphol airport to get onto the Rio flight which then parked on the tarmac for 2 hours due to the winds. Another roller-coaster ride across a turbulent North Atlantic and we finally arrived in Rio De Janeiro two hours late. Eventually managed to get the free shuttle to the Linx Hotel adjacent to airport Friday 19th January • Collected from the Linx by our very punctual driver (this was to be a theme) and 2.5hour transfer to Itororo Lodge through surprisingly light traffic. Birded the White Trail in the afternoon. Saturday 20th January • All day in Duas Barras & Sumidouro area. Luggage arrived. Sunday 21st January • All day at REGUA (Reserva Ecologica de Guapiacu) – wetlands and surrounding lowland forest. Andy was ill so guided by the very capable REGUA guide Adelei. Short visit late pm to Waldanoor Trail for Frilled Coquette & then return to lodge Monday 22nd January • All day around lodge – Blue Trail (am) & White Trail (pm) Tuesday 23rd January • Early start (& finish) at Pico da Caledonia. -
Patch Dynamics of Desert Fishes in the Arid Wetlands of Western Utah
AN ABSTRACT OF THE THESIS OF Jessica Sáenz for the degree of Master of Science in Fisheries Science presented on March 21, 2014. Title: Patch Dynamics of Desert Fishes in the Arid Wetlands of Western Utah Abstract approved: ______________________________________________________ James T. Peterson The conservation of declining desert fish species requires the identification of relations between fish population dynamics and their environments. Dynamic occupancy modeling, an approach that requires less information than traditional mark-recapture studies, may help identify important factors affecting population processes and aid desert fish conservation and restoration efforts. I used dynamic multi-season occupancy models for two analyses (multi-state and multi-species) to evaluate the influence of patch-level characteristics (patch percent open water, average patch depth, patch area), grazing damage, species interactions, population differences, patch connectivity and environmental variation (seasonal precipitation and temperature) on the patch dynamics (colonization, persistence, reproduction) of two desert chub species found in Snake Valley, UT. My results indicate that there was the strongest evidence according to model weights that patch dynamics in this system were influenced by patch-level characteristics (patch percent open water and average patch depth), grazing damage, population differences, biotic interactions, and winter precipitation rather than landscape level features such as connectivity. I observed positive effects of patch percent open water and average patch depth on least chub and Utah chub persistence. I also found that grazing damage increased their persistence at the medium damage level but decreased least chub and Utah chub colonization at the high grazing damage level. Least chub and Utah chub colonization varied between the two populations (study areas) with a higher probability of colonization at Bishop Springs than at Gandy Salt Marsh. -

Ectoparasitic Community of the Mahali Mole-Rat, Cryptomys Hottentotus
Fagir et al. Parasites Vectors (2021) 14:24 https://doi.org/10.1186/s13071-020-04537-w Parasites & Vectors SHORT REPORT Open Access Ectoparasitic community of the Mahali mole-rat, Cryptomys hottentotus mahali: potential host for vectors of medical importance in South Africa Dina M. Fagir1* , Nigel C. Bennett1†, Eddie A. Ueckermann2, Alexandra Howard1 and Daniel W. Hart1† Abstract Background: The endemic rodent family of Bathyergidae in Africa, particularly South Africa, are understudied as reservoirs of diseases of signifcant medical importance. Considering the diversity and wide distribution of African mole-rats in South Africa, many of these bathyergids could act as carriers of zoonoses. Methods: The present study assessed the ectoparasite community of the Mahali mole-rat (Cryptomys hottentotus mahali). We aimed to identify possible parasitic arthropods that may infest this mole-rat species and explore host preference, contributions of seasonality, host sex and body mass as well as social class and colony size on ectoparasite assemblage prevalence and abundance. Results: A limited number of ectoparasite species were found on C. h. mahali belonging to two signifcant taxa: mites (Acari) and feas, with mites being the most prevalent and abundant. We recorded the presence of X. philoxera, a fea well known as the principal reservoir of plague in the southern African region on the Mahali mole-rats. Only three mite species were collected: Androlaelaps scapularis, Androlaelaps capensis and Laelaps liberiensis. Seasonal peaks in prevalence and abundance of X. philoxera and A. scapularis were observed during summer. Xenopsylla philoxera abundance and A. scapularis loads signifcantly increased on reproductive mole-rat individuals in comparison to non- reproductive individuals.
