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

The cormorant Phalacrocorax carbo (Linnaeus, 1758) is a common breeding species at lake areas of Mongolia. Although molecular research has been conducted on many colonies worldwide, no studies of the genetic diversity of Mongolian colonies are known to date. In this study, we sequence for the first time a fragment of cytochrome oxidase 1 (CO1) from ten individuals of the 2017 resident population at Telmen-nuur. Here we perform molecular identification and analyze it in the context of existing data from populations studied worldwide. A clear assignment to the species P. carbo could be shown, but no identification on subspecies level …

The Palaearctic is a zoogeographical region where knowledge of the distribution, taxonomy and ecology of bats (Chiroptera) is generally quite extensive. However, for many Palaearctic subregions, including Mongolia, detailed knowledge is still quite scarce. Also for some groups of species there are only few studies available to date. This holds also true for the long-eared bats of the genus Plecotus. For the long-eared bats, which live in close family groups and do not migrate over long distances, the development of different life form types can be expected. Studies tackling this are so far lacking.

The fundamental revision of the …

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

The Great Cormorant Phalacrocorax carbo is a wide spread breeding species in Mongolia with a progressive population trend. Observations of the Mongolian-German Biological Expeditions were analyzed and summarized with data from literature. About 1,500 young birds were ringed in 2016 and 2017. One important recovery was coming from the wintering area Mai Po Marshes Nature Reserve of Hong Kong. It is unclear if all Mongolian Cormorants are flying at the same route to their wintering region in South China. The main feeding fishes in Mongolia belong to endemic species of the genus Oreoleuciscus (Cyprinidae). Measurements of 113 eggs from Tolbo- …

Mist-Netting Of Forest-Dwelling Bats In The Lazovsky State Nature Reserve, Russian Far East, Kerstin Birlenbach

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

Many bat species depend on a high value of healthy and undisturbed forests with a high ratio of roost sites in old tree stands. This investigation focused on the diversity, distribution and reproduction status of bats within the area of Lazovsky State Nature Reserve. The importance of an area for bats can be measured by the ratio of reproduction. The most important and sensitive time in a bats yearly circle is the time of hibernation in winter and the reproduction time of females. From the beginning of July to the end of August 2007, in total 139 bats of eight …

The Formation Of Aufeis And Its Impact On Infrastructure Around Ulaanbaatar, North-Central Mongolia, Michael Walther, Vanchindorj Batsaikhan, Avirmed Dashtseren, Yamkhin Jambaljav, Khurelbaatar Temujin, Ganbold Ulanbayar, Ulrich Kamp

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

In this study aufeis features and their formation under natural conditions and in an urban surrounding in north-central Mongolia were investigated. Used methods included field observations, Electrical Resistivity Tomography (ERT) as well as analyses of satellite imagery and meteorological data. Aufeis formation is related to streams, springs, and ground conditions, particularly soil moisture; the formation of both spring aufeis and river aufeis follows a seasonal cycle. The meteorological data from 1969 to 2018 indicate that the mean annual air temperature (MAAT) increased by 2.6 °C, whilst no significant changes were observed for precipitation. Between 1992 and 2018, aufeis areas significantly …

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

Although the house mouse as a common and widely distributed species is probably best-studied among small mammals, there is a lack of fundamental knowledge regarding species identity, morphology and ecology in Mongolia. Consequently, this study provides results of basic biological research on the Mongolian house mouse. A total of 172 specimens have been studied based on samples collected during the period 1962 to 2016. Using genetic and morphological markers, the taxonomic examination resulted in classification as Mus musculus musculus LINNAEUS, 1758. To characterize the Mongolian house mouse, three fur color traits and 23 metric body and skull traits were analyzed. …

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

Remote sensing and satellite telemetry have allowed to greatly expanding the understanding of how species use various landscapes, even in remote settings. However, remotely collecting data also harbors the risk of losing “touch with the ground.” We explore the possibility of the additional insight cameras integrated in GPS-satellite collars can provide for the behavior and ecology of free-ranging Przewalski’s horse in the remote Great Gobi B Strictly Protected Area in southeastern Mongolia. Over a 91-day period, the camera collected 1,080 images. 62% of the images showed Przewalski’s horses and provided insights into behavior and grouping patterns and can supplement indirect …

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

Between 2008 and 2014, four Mongolian-German Biological Expeditions worked for short periods in East Mongolia. The results related to mammalian fauna were summarized. Investigation areas were parts of the Daurian steppe, Buir-nuur- and Nömrög-gol-region. Chiroptera were recorded with four species. Especially, Vespertilio sinensis has to be considered as a characteristic species of the eastern steppes. Aggregations of some thousand individuals were found in the Buir-nuur-region. The other three species were Plecotus ognevi, Myotis petax, and Myotis aurascens. It is to expect, that in eastern Mongolia some more Chiroptera-species will re-covered in future.

Effects Of Salt Runoff On Aquatic Macroinvertebrate Colonies, Kendra Fink

Journal of Earth and Life Science

Aquatic macroinvertebrates bridge the gap in part between primary and secondary consumers, making them ecologically important for most aquatic systems. They are used as biotic indicators for water quality due to their sensitivity to pollutants and may be affected, specifically, by chloride ion concentrations in the water. Water quality can be evaluated by looking at species compositions and their respective tolerance values. To determine long-term effects of road salt on macroinvertebrate colonies, a total of 338 identified macroinvertebrates of 10 families (two generalized to class) at 9 sites were collected from before, after, and between three bridges on Turtle River …

Modelling Climatic And Temporal Influences On Boating Traffic With Relevance To Digital Camera Monitoring Of Recreational Fisheries, Ebenezer Afrifa-Yamoah, Stephen M. Taylor, Ute A. Mueller

Research outputs 2014 to 2021

Digital camera monitoring data on recreational boating traffic are often manually interpreted and the reading cost can be expensive. Typically, these data are used along with other periodic survey information and camera data between these surveys may not be read, creating gaps in the time series. We predicted recreational boating traffic during these ‘gap’ periods using historical camera data and covariates to complete the time series data. Predictive models were built in a Bayesian regression modelling framework to determine the daily distribution of recreational boating traffic at two ramps in Western Australia based on climatic variables (temperature, humidity, wind speed, …

Effects Of Predator Management And Parasitism On Over-Water Nesting Diving Duck Production In Southwestern Manitoba, Trenton E. Rohrer

Electronic Theses and Dissertations

Nest survival of upland nesting waterfowl (e.g., mallard [Anas platyrhynchos], blue-winged teal [Anas discors]) has been studied extensively in the Prairie Pothole Region (PPR) of North America. Conversely, over-water nesting diving ducks’ nest survival is poorly understood, likely because over-water nests are more challenging to find, may be less concentrated, and searching for these nests is physically demanding. Nest depredation is considered a leading cause of duck nest failure and is considered a limiting factor on upland nesting waterfowl production in the PPR. Similar factors limiting upland nesting duck production may limit over-water nesting duck productivity, but studies of this …

Impacts Of Extreme Environmental Disturbances On Piping Plover Survival Are Partially Moderated By Migratory Connectivity, Kristen S. Ellis, Michael J. Anteau, Francesca J. Cuthbert, Cheri L.

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Effective conservation for listed migratory species requires an understanding of how drivers of population decline vary spatially and temporally, as well as knowledge of range-wide connectivity between breeding and nonbreeding areas. Environmental conditions distant from breeding areas can have lasting effects on the demography of migratory species, yet these consequences are often the least understood. Our objectives were to 1) evaluate associations between survival and extreme environmental disturbances at nonbreeding areas, including hurricanes, harmful algal blooms, and oil spills, and 2) estimate migratory connectivity between breeding and nonbreeding areas of midcontinental piping plovers (Charadrius melodus). We used capture …

Red Drum And Spotted Seatrout Live-Release Tournament Mortality And Dispersal, T. Reid Nelson, Crystal Hightower, Sean P. Powers

University Faculty and Staff Publications

Although catch-and-release fishing tournaments undoubtedly reduce mortality of target species, postrelease mortality and fish stockpiling at release sites remain common concerns related to these tournaments. The impacts of liverelease tournaments on freshwater species have been widely studied. However, research on estuarine sport fishes is lacking even though catch-and-release tournaments targeting these species are prevalent and popular recreational fisheries exist. Therefore, we estimated the post-weigh-in mortality and dispersal of Red Drum Sciaenops ocellatus and Spotted Seatrout Cynoscion nebulosus released from the 2016–2018 Alabama Deep Sea Fishing Rodeo live-weigh-in categories using acoustic telemetry. To concurrently estimate overall post-weigh-in mortality and dispersal, we …
