The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Faculty Research & Creative Activity

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …

Effects Of Natural History On Osmoregulatory Behaviors In Two Stream-Dwelling Frogs (Pseudacris Cadaverina And P. Regilla), Heidy Lorena Contreras

Theses Digitization Project

Differences in osmoregulatory behaviors were studied in two stream-dwelling tree frogs (Pseudacris cadaverina and P. regilla) with different natural histories. This study supports the idea that the natural history of a species has a strong effect on behavior associated with osmoregulation.

A Geographically Constrained Molecular Phylogeny Of Panamanian Aechmea Species (Bromeliaceae, Subfamily Bromelioideae), Keri Renee Maher

Theses Digitization Project

This study lends strong support to the idea that members of Bromeliaceae have undergone a recent adaptive radiation, and therefore show that, at least in part, diversity in the tropics is due to a fast speciation rate and that the tropics can be a "cradle" for new diversification and exploitation of varying ecological niches through the diversification of ecophysiological traits within a lineage.

The Effect Of Male And Female Body Size On Mating Behavior Of Male Fairy Shrimp, Eubranchipus Neglectus, Craig Feigenbaum, Paul V. Switzer

Faculty Research & Creative Activity

We studied size-related mating patterns in the freshwater fairy shrimp Eubranchipus neglectus in the laboratory. Males were provided with relatively small or large females that they could only sense by vision. We recorded the number of times a male pursued the female (“follows”), the duration of these follows, and the number of times a male attempted to grasp the female. Relatively large males performed more mating behavior than relatively small males. Furthermore, males (regardless of their own size) exhibited more mating behavior towards large than small females. They followed large females more frequently, attempted to grasp large females more often, …

The Demographics Of The U.S. Equine Population, Emily R. Kilby

State of the Animals 2007

In this demographic examination of America’s equine population, the numbers clearly show upward trends in all things equestrian over the past fifty years. Will that trajectory continue, adding year after year to the current ten million population, or will loss of open spaces turn the tide as it limits horse housing and riding room? Will ownership patterns undergo fundamental changes when population density, land costs, and escalating environmental controls eliminate the “backyard”- keeping concept and make suburban boarding stables untenable? Will horse production expenses rise in the face of land pressures to the point that equestrian involvement, now a highly …

The Steady State Economy, Habitat Stability, And The Humane Treatment Of Wild Animals, Brian Czech

State of the Animals 2007

Economic growth is not intended to kill, torture, or harass animals, and in that respect is not as detestable as various other forms of inhumanity. Yet economic growth is surely the greatest of all forms of inhumanity in terms of the gross amount of wild animal suffering that results. Therefore, for those concerned with the humane treatment of wild animals, perhaps nothing is so important to address as the policy and process of economic growth.

Free-Roaming Dogs In Developing Countries: The Benefits Of Capture, Neuter, And Return Programs, Jennifer Jackman, Andrew N. Rowan

State of the Animals 2007

This chapter provides an overview of animal welfare and public health problems associated with free-roaming dog populations and strategies to resolve these problems. Placing CNR programs in the context of earlier dog and rabies control methods, the chapter explores CNR’s potential to overcome some of the shortcomings of earlier approaches and to improve animal welfare, reduce dog population growth, and prevent the spread of rabies and other canine-transmitted diseases. Constraints and current debates on current implementation of CNR programs are also examined.

How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder

Sentience Collection

The notion ‘quality of life’ (QoL) suggests that welfare in animals encompasses more than just an absence of suffering; it concerns the quality of an animal’s entire relationship with its environment, of how it lives its life. Judgements of such quality are based on the integration of perceived details of how animals behave over time in different contexts. The scientific status of such judgements has long been ambiguous, but in recent decades has begun to be addressed by animal scientists. This paper starts with a brief review of qualitative approaches to the study of animal behaviour, which tend to address …

Stable Isotopic Niche Predicts Fitness Of Prey In A Wolf–Deer System, C. T. Darimont, P. C. Paquet, T. E. Reimchen

Evolutionary Biology Collection

Interindividual variation in niche presents a potentially central object on which natural selection can act. This may have important evolutionary implications because habitat use governs a suite of selective forces encountered by foragers. In a free‐living native black‐tailed deer, Odocoileus hemionus, population from coastal British Columbia, we used stable isotope analysis to identify individual variation in foraging niche and investigated its relationship to fitness. Using an intragenerational comparison of surviving and nonsurviving O. hemionus over 2 years of predation by wolves, Canis lupus, we detected resource‐specific fitness. Individuals with isotopic signatures that suggested they foraged primarily in cedar ( …

Structural Stability And Endonuclease Activity Of Pi-Scei Gfp-Fusion Protein, Ali Senejani, Peter J. Gogarten

Biology and Environmental Science Faculty Publications

Homing endonucleases are site-specific and rare cutting endonucleases often encoded by intron or intein containing genes. They lead to the rapid spread of the genetic element that hosts them by a process termed ‘homing’; and ultimately the allele containing the element will be fixed in the population. PI-SceI, an endonuclease encoded as a protein insert or intein within the yeast V-ATPase catalytic subunit encoding gene (vma1), is among the best characterized homing endonucleases. The structures of the Sce VMA1 intein and of the intein bound to its target site are known. Extensive biochemical studies performed on the PI-SceI enzyme provide …

A Taxonomic Investigation Of The Black Ratsnake, Elaphe O. Obsoleta (Say) [Reptilia, Squamata, Colubridae], In West Virginia Using Morphometric Analyses, Adam M. Mann

Theses, Dissertations and Capstones

A recent genetic study by Frank T. Burbrink (2000) determined that the common Black Ratsnake, Elaphe o. obsoleta, evolved from three separate evolutionary lineages and can no longer be classified under a single species name. The newly assigned species, which possess ranges that are separated into three regions of the eastern United States by geologic features such as rivers and mountains, are also said to possess distinct morphologic characteristics (Burbrink, 2001). This thesis study was initiated to mirror Burbrink’s previous morphometric study and augment a previous lack of specimen data from West Virginia. Black Ratsnake museum specimens, collected from ranges …

Behavioural Plasticity In An Ecological Generalist: Microhabitat Use By Western Fence Lizards, Dee A. Asbury, Stephen C. Adolph

All HMC Faculty Publications and Research

Question: What is the basis for geographic variation in microhabitat use in fence lizards?

Hypothesis: Population differences in microhabitat use reflect behavioural plasticity rather than genetic or experiential differences.

Organisms: Western fence lizards (Sceloporus occidentalis).

Field site: Three sites (desert, valley, and mountain) in southern California, USA.

Methods: We compared habitat use by free-ranging lizards in three field populations. We also collected lizards from these three populations and studied their microhabitat use in experimental enclosures at a single field site.

Results: In the wild, lizards chose higher and shadier perches at the hottest (desert) site, lower and sunnier perches at …

A New Satellite-Based Methodology For Continental-Scale Disturbance Detection, David J. Mildrexler, Maosheng Zhao, Faith Ann Heinsch, Steven W. Running

Ecosystem and Conservation Sciences Faculty Publications

The timing, location, and magnitude of major disturbance events are currently major uncertainties in the global carbon cycle. Accurate information on the location, spatial extent, and duration of disturbance at the continental scale is needed to evaluate the ecosystem impacts of land cover changes due to wildfire, insect epidemics, flooding, climate change, and human-triggered land use. This paper describes an algorithm developed to serve as an automated, economical, systematic disturbance detection index for global application using Moderate Resolution Imaging Spectroradiometer (MODIS)/Aqua Land Surface Temperature (LST) and Terra/MODIS Enhanced Vegetation Index (EVI) data from 2003 to 2004. The algorithm is based …

Sensitivity Of Pan-Arctic Terrestrial Net Primary Productivity Simulations To Daily Surface Meterology From Ncep-Ncar And Era-40 Reanalyses, Ke Zhang, John S. Kimball, Maosheng Zhao, Walter C. Oechel, John Cassano, Steven W. Running

Ecosystem and Conservation Sciences Faculty Publications

We applied a terrestrial net primary production (NPP) model driven by satellite remote sensing observations of vegetation properties and daily surface meteorology from the 45-year ECMWF Re-Analysis (ERA-40) and the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP-NCAR) reanalysis (NNR) to assess NPP spatial and temporal variability for the pan-Arctic basin and Alaska from 1982 to 2000. Sensitivity analysis of the production efficiency model (PEM) to uncertainties in surface meteorological inputs indicate that ERA-40 solar radiation and NNR solar radiation and surface temperatures are the primary sources of PEM-based NPP uncertainty for the region. Considerable positive bias in …

Geographic Distribution: Ramphotyphlops Braminus (Brahminy Blindsnake). Usa: Florida: Alachua Co., Louis A. Somma

Papers in Herpetology

One adult within a temiite colony, beneath rock. UF 151211; additional specimens (UF 151212-14) were also found. All specimens were collected between 1200-1240 h at the Division of Plant Industry (DPI), Florida Department of Agriculture and Consumer Services. In 2006, another adult Ramphotyphlops braminus was collected by an employee at this site, near a greenhouse, and was kept in captivity until it escaped. Rhamphotyphlops is occasionally encountered by employees of DPI and it may be expanding its range, as there is one specimen (UF 147001) collected from the University of Florida campus (Powell Hall) adjacent to the DPI site (29°38'7.9080"N, …

Morphology, Reproduction And Mortality Of Equus Hemionus Hemionus In Mongolia, Annegret Stubbe, Michael Stubbe, Nyamsuren Batsaikhan

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

There are collected materials on morphology, reproduction rate, and mortality of Dschiggetajs Equus h. hemionus between 2001 and 2006 in the South Gobi of Mongolia. It were found 794 skeletons of wild asses, 95% of these were pouched, ⅔ of them in winter coat. Pouching was also located in the protected areas of this region. The main living resources of Equus hemionus are registered in the South eastern Gobi. For the first time statistical data on morphology measurements of body length, tail and tuft, ear length, and hoofs are given. There are no significant differences between the sexes. The reproduction …

Up-Date On The Behaviour And Status Of The Critically Endangered Onager, Equus Hemionus Onager, From Iran, Laurent Tatin, Bijan F. Darreh-Shoori, Christophe Tourenq, David Tatin, Bijan Azmayesh

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The onager, Equus hemionus onager, an Asiatic wild ass endemic to Iran, is categorized as Critically Endangered on the IUCN Red List. Its biology and conservation requirements are poorly documented. We report some observations made in 1997 and 2000 on the behavior and ecology of the two remaining populations, located in the Touran Protected Area and the Bahram-e-Goor Reserve. Recent population counts by the Department of Environment of Iran (471 in the Protected Area, and 96 in the Reserve) are markedly lower than the count of 600-770 made in the 1970s in the Touran Protected Area. We observed social …

Asiatic Wild Ass In Israel, David A. Blank

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The Syrian wild ass (Equus hemionus hemippus) lived in Israel in historic times until the 1930s, when it disappeared from the entire Middle East region. Khulans from other subspecies (E. h. onager - six individulas and E. h. kulan - five individuals) were brought to Israel from European zoos during 1968-69 (the authors of project considered that onager and kulan were the same subspecies) and these animals bred together in the semi-captivity conditions of the Haibar Yotvata Reserve. Later, during a 12-year period from 1982 through 1993, six groups totalling 38 khulans (17 males and 21 females) …

Surviving A Drought: Population Dynamics Of Ochotona Pallasi Pricei In A Dry Steppe, Gobi Altai, Mongolia, Karin Nadrowski, Georg Miehe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Two distinct life history traits are described from the genus Ochotona, the group of “burrowing” species exhibiting high but fluctuating population densities and the “non-burrowing” species exhibiting relatively stable low population densities. The life history traits are linked to ecosystem dynamics with climatically variable steppe environments hosting “burrowing” species and relatively stable mountainous and rocky habitats hosting “non-burrowing” species. There are few intermediate species, living in both steppe and rocky environments. This study presents survival rates, reproductive rates and a tentative model of population dynamics for Ochotona pallasi pricei, an intermediate species with respect to habitat preference. We …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The history of the discovery and the exploration of the hemione populations (Equus hemionus PALLAS) from Central Asia (Mongolia, northwest China, northeast Tibet, Kazakhstan, and Russian Siberia) from the 13th century to approximately 1950 are compiled with the aim to provide materials for a taxonomic and population genetic revision of the dziggetais. Data on their phenotypic differentiation, historical distribution status, and their husbandry history in European zoological gardens, are reviewed, as is the gradual emergence of concepts of how to identify and to classify these populations. Hemiones were an important historical case in the discussion of how to represent …

Quo Vadis Equus Hemionus Hemionus In Mongolia?, Annegret Stubbe, Michael Stubbe, O. Shagdarsuren, Ravčigijn Samjaa, Nayamsuren Batsaikhan

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Caused in studies on biodiversity in the South Gobi we were confronted with the human impact on animal communities and endangered animal species, especially the Asiatic wild ass. So was born the idea to organize an international conference with the aim to actualize the status of Equus hemionus in Central Asia and to find ways for better conservation of this species and its habitats. A short review is given on historical exploration, decreasing area and population number of the Dschiggetai. Today the range of the nominate form of Equus hemionus is located in the Gobi region of southern Mongolia/northern China …
