Review Of Montana Euphilotes Mattoni, [1978], With Descriptions Of New Taxa (Lepidoptera: Lycaenidae: Polyommatinae), Steve Kohler, Andrew D. Warren
The Taxonomic Report of the International Lepidoptera Survey
The genus Euphilotes at the northern end of its distribution is reviewed, with special emphasis on populations in Montana. Also discussed are some Euphilotes populations in Oregon, Washington, Idaho, and southwestern Canada that have affinities with Montana. This region has until recently been essentially neglected in studies of the genus. We characterize and discuss six species (two newly described) and twenty-five subspecies (six newly described) of Euphilotes, including a number of yet undescribed populations. New species include E. heracleoides Kohler & A. Warren (type locality in Sanders County, Montana) and E. oakleyi Kohler (type locality in Missoula County, Montana). …
Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso
Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Dekay’s Brownsnake (Storeria dekayi) generally occurs in southeastern parts of the state, where the species was known from 16 counties. Herein, we update the distribution of S. dekayi in the state and briefly comment on habitat and abundance from observations in September and October 2018. We documented 7 new county records that extend its distribution in south-central Nebraska. We observed that S. dekayi does not only reside in mesic wooded habitats in Nebraska but also occupies open environments, including areas with upland grasslands and row-crop agriculture. Dekay’s Brownsnake currently is listed as a species of concern …
A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall
A Lobed Argiope Spider On Its Most Eastern Distribution – First Record Of Argiope Lobata (Pallas, 1772) For The Sub-Family Argiopinae (Arachnida: Araneidae) In Mongolia, Oliver Lindecke, Marcus Wall
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The subfamily Argiopinae SIMON, 1890 is reported for Mongolia the first time by Argiope lobata (PALLAS, 1772). Furthermore, we herein highlight the most eastern distribution of this species, which is widespread in the Mediterranean, African and in some Asian countries. The obtained specimen was found in the Eastern Gobi, a landscape of semi-desert character. Despite numerous studies with arachnological background in the past, even larger species new for Mongolia could be found. Findings like this show the on-going need for basic biodiversity research in the Gobi ecoregions. We further discuss previous, but doubtful reports of A. lobata in South-east Asia …
Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard
Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard
Zea E-Books Collection
Based on an analysis of 47 years (1967–2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root’s 1988 Atlas of North American Wintering Birds. Root’s landmark study provided a baseline for evaluating the nationwide winter distributions of 253 North American birds in the mid-20th century, using data from the National Audubon Society’s …
Current Status Of Lesser Sandhill Cranes In Yakutia, Inga Bysykatova, Sergey Sleptsov, Nikolay Vasiliev
Current Status Of Lesser Sandhill Cranes In Yakutia, Inga Bysykatova, Sergey Sleptsov, Nikolay Vasiliev
Proceedings of the North American Crane Workshop
In Yakutia, the sandhill crane (Grus canadensis canadensis) was considered a common bird in 1957 on the Primorie tundra from the Kolyma River to the Alazeya River. In 1980 the area of the species’ supposed breeding grounds within the Kolyma- Indigirka interfluve comprised 34,600 km2. In 1984-85, the breeding grounds extended west to the Sundrun River, with the total area reaching 49,400 km2. At present, the westernmost sandhill crane range is on the tundra along the lower reaches of the Berelekh River. This region joins the higher density Siberian crane (G. leucogeranus) range, so that the …
Wintering Sandhill Crane Distribution And Habitat Use Patterns At Bosque Del Apache National Wildlife Refuge, New Mexico, Tandi L. Perkins, Leigh H. Fredrickson
Wintering Sandhill Crane Distribution And Habitat Use Patterns At Bosque Del Apache National Wildlife Refuge, New Mexico, Tandi L. Perkins, Leigh H. Fredrickson
Proceedings of the North American Crane Workshop
The single most important factor regulating sandhill crane (Grus canadensis) populations is their ability to carry out annual life cycle events while responding to changing habitat availability and distribution across local, regional, and continental landscapes. Wetland and cropland resource availability and distribution across the landscape have become increasingly unpredictable. Recent changes in farming practices, urbanization, and prevailing drought conditions in New Mexico have transformed and reduced dynamic, heterogeneous landscapes into scattered fragments of the original setting. Concerns are increasing for the cumulative influence of these often irreversible actions in providing the type of resources needed by cranes at …
Preliminary Wintering Counts And New Locations Of Sandhill Cranes In Mexico, Ingrid Barceló, Edgar G. López, Felipe Chávez-Ramírez
Preliminary Wintering Counts And New Locations Of Sandhill Cranes In Mexico, Ingrid Barceló, Edgar G. López, Felipe Chávez-Ramírez
Proceedings of the North American Crane Workshop
Sandhill cranes (Grus canadensis) undertake a migration twice a year, when more than 400,000 cranes cross the United States from the Arctic of North America and Eastern Siberia to the southwest U.S. and north central Mexico. Although the sandhill crane has been studied intensely, few studies have been done on their Mexican wintering grounds. Little is known about what proportion of the sandhill crane population migrates to Mexico, and there is even less information regarding its dispersion. During winter 2007-2008 we surveyed 30 wetlands in the Chihuahuan Desert ecoregion in northern Mexico, recording presence/absence and number of sandhill …
Study Of Environmental Variables And Connectivity Of Northern Mexico For Cranes: Conservation Implications, Edgar Gustavo López-Saut, Ricardo Rodriguez Estrella, Felipe Chavez-Ramirez
Study Of Environmental Variables And Connectivity Of Northern Mexico For Cranes: Conservation Implications, Edgar Gustavo López-Saut, Ricardo Rodriguez Estrella, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
Wetlands are one of the most important ecosystems for biodiversity and as a resource for humans. Humans depend on wetlands for water and food, but with expansion of urban cores, water overexploitation, and the increase of croplands, wetlands are at risk. The Chihuahuan desert is an ecoregion important for the economy and development of Mexico. Although there are many temporal wetlands that support many migratory birds, water in some desert landscapes is being overexploited due to development. This leads to the desiccation of wetlands important for migratory birds such as cranes. The cranes as a group are associated with grasslands …
Distribution An D Dispersion Patterns Of San Dhill Crane Flocks In The Platte River Valley, Brian Lorenz, Felipe Chavez-Ramirez
Distribution An D Dispersion Patterns Of San Dhill Crane Flocks In The Platte River Valley, Brian Lorenz, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
We evaluated sandhill crane (Grus canadensis) flock distribution and dispersion patterns along the Platte River Valley, Nebraska, in 2002-2003. The objectives were to: (a) determine the overall distribution and relationship between roosting and foraging flock numbers by bridge segments, (b) evaluate flocking characteristics in relation to abundance of cranes in different bridge segments and total abundance, and (c) correlate dispersion patterns and habitat use to period of migration, roost locations, and habitat types. Preliminary predictions included: foraging flock dispersions would be correlated with roost locations; greater numbers and larger flock sizes will be present in bridge segments with …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The kulan (Equus hemionus kulan) is the only odd-toed ungulate left in the wild in northern Eurasia. In the 1930s, the kulan survived in southern Turkmenistan only. In the 1940s, kulans were found only in an area named Badkhyz in Turkmenistan. To conserve the last natural population of this subspecies of kulan the Badkhyz Natural Reserve was established in 1941. The historical and contemporary distribution, fluctuation in numbers, conservation and sci research of kulan populations in the Badkhyz Natural reserve are reviewed in this paper.

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
In September - October 1998 we made an extensive survey in southwest Tibet to study numbers, distribution and social structure of the kiang population in this remote part of its range. Kiangs were sighted between 29º 40’ and 32º 50’ N, and 81º- 86º E. They preferred broad flat valleys with lakes at an altitude from 4,000 up to 5,000 m. Small kiang groups and solitary animals were sighted in Transhimalaya. There were no kiangs in Tsangpo (Brahmaputra) River valley, in the sand desert near Ali and in the Clay Mountains near Tsada. Seven old kiang corpses were found along …
New Locations And Range Extension Of Wintering Sandhill Cranes In Central Northern Mexico, Felipe Chavez-Ramirez
New Locations And Range Extension Of Wintering Sandhill Cranes In Central Northern Mexico, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
The overall distribution of wintering sandhill cranes in Mexico has been reported and summarized in several prior documents. However, most reports are associated with counts or surveys primarily conducted for wintering waterfowl. Recent (1999- 2002) reports compiled from local researchers show, that wintering sandhill cranes are distributed much more widely in northern Mexico than is currently reported in the literature. The new locations reported here are primarily in the eastern portion of the Mexican Altiplano, in the states of Coahuila and Nuevo Leon, and in the southern portions of the Chihuahuan Desert Region in Zacatecas and San Luis Potosi. Most …

Migration Chronology, Routes, And Distribution Of Pacific Flyway Population Lesser Sandhill Cranes, Michael J. Petrula, Thomas C. Rothe
Proceedings of the North American Crane Workshop
Managers of migratory game birds require accurate information about bird movements to delineate populations, protect important habitats, and regulate harvest. Data describing movements of sandhill cranes (Grus canadensis) belonging to the Pacific Flyway Population (PFP) are lacking. We used satellite telemetry to monitor movements of PFP lesser sandhill cranes (Grus c. canadensis) captured in the upper Cook Inlet and Bristol Bay regions of Alaska. Satellite transmitters were deployed on 19 flightless young (colts) and 3 adults over 3-years (2000-2002). Chronology, routes, and stopover or staging areas were identified for fall and spring migration periods. On average, …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Microtus brandti is one of the most important pest species of Mongolian rodents. Since the publication of Bannikov (1954) the area of expansion is increased, in the Archangaj-Aimag 200 km westward, in the Central Aimag 70 km to the North and in the north-eastern part of Dornogov’- Aimag about 110 km to the South. In years of gradation the plant cover was exterminated up to 100%. We can distinguish a zone of exposed harmfulness with a damage of 70-100%. In this region 16 great centers of infestation were listed. Between 1925 and 1985 six important calamities were noticed, in intervals …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The population of the Mongolian wild ass belongs to the nominate form Equus hemionus hemionus described by Pallas in 1775. This species is adapted to semidesert habitats in the Gobi region and is listed in the Red Book of Mongolia as well as on appendix I of the Washington Convention (CITES). Mapping of the northern border of the distributional range showed a remarkable decrease in size in comparison to the maps of Murzaev (1954) or Bannikov (1954). The pressure of civilization, settlements, motorization, and increasing numbers of domestic livestock in connection with the occupation of water resources and illegal hunting …
