Whooping Crane Collisions With Power Lines: An Issue Paper, Thomas V. Stehn, Tom Wassenich

Proceedings of the North American Crane Workshop

Collision with power lines is the greatest source of mortality for fledged whooping cranes (Grus americana) in the Aransas-Wood Buffalo population (AWBP) that migrate between the Northwest Territories, Canada to the Texas coast. This paper compiles 45 documented whooping crane mortalities from power line strikes in North America and provides known information on crane / power line interactions. A map of the AWBP whooping crane migration corridor was derived with 100 and 200-mile wide corridors delineated showing the location of known mortalities. Recommendations are provided to try to reduce this major threat facing whooping cranes.

A Year-Long Study Of Food Consumption By Captive Whooping Cranes At The International Crane Foundation, Jessica J. Stocking, Michael S. Putnam, Nathanial B. Warning

Proceedings of the North American Crane Workshop

Throughout 2002, we recorded daily food consumption by 12 pairs of captive whooping cranes (Grus americana). For 7 pairs we recorded food consumption throughout the entire year while there were large continuous gaps in measurements of food consumption for 5 pairs that raised chicks that year. Birds received both a maintenance and breeder diet, and for both we converted food consumption to energy intake (Joules/g body mass) using the combined fall weights of female and male. We compared daily energy intake with 6 meteorological variables (involving temperature, wind speed and humidity), photoperiod (natural and artificial) and egg laying …

Florida Crane habitat resolution
Florida has the largest population of non-migratory sandhill cranes in the world and winters a significant portion of the eastern population of greater sandhill cranes. And in Florida, efforts are underway to introduce migratory and non-migratory whooping cranes. In order to successfully establish and sustain these populations, appropriate habitat needs to be available. About 40% of Florida’s best crane habitat has been lost between 1973 and 2003, and the amount has increased since then. Because of this, these valuable populations of cranes are finding it more difficult to locate suitable habitat. We the NACWG by this …

Waterhole Dynamics And Chemical Signals Of African Elephants ( Loxodonta Africana ), Stacie Marie Castelda

College of Graduate Studies: Theses & Dissertations

The distribution of mammals in a savanna environment is influenced by abiotic and biotic factors. The African savanna experiences distinct wet and dry seasons. Species become spatially restricted around water resources during the dry season, resulting in increased intraspecies and interspecies resource-based aggregation. A dominate species, such as the African elephant (Loxodonta africana), may influence this aggregation. I examined the influence of wet and dry seasons and ambient temperature on the use of a waterhole by elephants as well as the co-occurrence of elephants and other mammals at the waterhole. Biodiversity scans (October 2004-June 2007) and were performed at a …

Project Limulus: What Long-Term Mark/Recapture Studies Reveal About Horseshow Crab Population Dynamics In Long Island Sound, Mark Beekey, Jennifer Mattei

Biology Faculty Publications

Project Limulus is a long-term study of the population dynamics of the horseshoe crab population in Long Island Sound (LIS). We have tagged over 20,000 spawning adults from >20 beaches ranging from Greenwich to Stonington, CT since 1997. Cumulative recapture rates have reached 9%. On average 90% of the crabs are recaptured within a few miles of their original tag site within the first season. Between seasons, on average, 45% of crabs are recaptured within the same locality of where they were tagged. Of all recaptures, 99% of recaptured individuals are found within LIS. This past year we expanded the …

Designation Of A Neotype For Leptodactylus Gracilis (Duméril And Bibron, 1840) (Amphibia: Leptodactylidae), Rafael O. De Sá, A. Dubois, A. Ohler

Biology Faculty Publications

The examination of the preserved specimens in the herpetological collection of the Museum National d'Histoire Naturelle, along with a review of the original literature, indicates that no extant specimen can be undoubtedly identified as the holotype of Leptodactylus gracilis (DumCri.l and Bibron, 1840). Furthermore, it revealed that the type locality recently assigned to this taxon is in error.

Description Of The Tadpole Of Leptodactylus Pustulatus Peters, 1870 (Anura: Leptodactylidae), Rafael O. De Sá, Reuber Brandão, Lorena Dall'ara Guimarães

Biology Faculty Publications

The external morphology and oral disc of the tadpole of Leptodactylus pustulatus Peters, 1870, are described and illustrated for Gosner stage 39. The internal oral anatomy was analyzed with SEM at Gosner stage 36 whereas chondrocranial anatomy is reported for Gosner stage 35. The overall characteristics do not depart from those known for the genus Leptodactylus and they particularly agree for those of the melanonotus species group. The labial tooth row formula is 2(2)/3. Observations are presented that suggest that L. pustulatus engages in larval parental care.

A Description Of A New Subspecies Of Lycaena Phlaeas (Lycaenidae: Lycaeninae) From Montana, United States, With A Comparative Study Of Old And New World Populations, Steve Kohler

The Taxonomic Report of the International Lepidoptera Survey

The Palaearctic, Oriental, and Ethiopian Region subspecies of Lycaena phlaeas are briefly discussed. A more detailed account of the North American subspecies is presented, and a new subspecies, L. p. weberi, from the Sweet Grass Hills, Montana is described. The possibility that the eastern United States subspecies hypophlaeas was introduced from the Old World is discussed; however no conclusion can be reached with certainty. The relationship between Old World and New World subspecies of L. phlaeas is discussed. Evidence presented supports the treatment of New World populations as subspecies of L. phlaeas.

Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric T. Schultz, Jose J. Pereira, Peter J. Auster

EEB Articles

Winter flounder (Pseudopleuronectes americanus) come inshore during the late winter and early spring to lay their eggs in shallow bays and estuaries along the coast. Unlike most fish eggs, which are buoyant, these eggs are demersal and sink to the seafloor. This makes them vulnerable to burial from various types of natural and human caused disturbances (e.g., storms, mobile fishing gear, maintenance dredging). Our objective was to map spawning areas in two harbors and search for generalities among these sites that would allow us to predict where winter flounder might spawn in other areas. This would allow managers to avoid …

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, Nyamsuren Batsaikhan, Ravčigijn Samjaa

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

Inspired by 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 the idea was born 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 …

Remarks On The Social System Of The Mongolian Wild Ass (Equus Hemionus Hemionus), Gertrud Neumann-Denzau, Helmut Denzau

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

So far the social system of Mongolian wild asses is non-uniformly interpreted. The authors describe their own observations from different parts of Mongolia and review data from available publications. The arguments support a territorial social system, which agrees with the social system of all other wild asses in Asia and Africa.

Asiatic Wild Asses In The Literature: What Do We Need To Know Now?, Sarah R.B. King

Asiatic wild asses were once found across central Asia, but over time their range has been reduced until today all subspecies are under threat. This paper examined the literature about wild asses with an aim to illustrating gaps in our knowledge as a target for future research.

A search was made on BIOSIS ISI for the following strings: Equus hemionus, wild ass, khulan, kulan, kiang, khur, and onager. In total 61 relevant references were found, published between 1900 and 2005. Most of these references were published in the 1990s, with only one published between 1900 and 1970. Khur and …

Comparative Demography And Dietary Resource Partitioning Of Two Wild Ranging Asiatic Equid Populations, Ellen Schulz, Thomas Kaiser, Annegret Stubbe, Michael Stubbe, Ravčigijn Samjaa, Nyamsuren Batsaikhan, Joachim Wussow

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

Tooth wear signatures allow inference on the dietary traits of herbivorous ungulates. Comparing dietary regimes of taxonomically closely related populations further allows inference on habitat structure and food availability. The mesowear method of tooth wear evaluation has opened up a pathway to reconstruct subtle differences in dietary behavior and resource partitioning based on skeletal material as the only source of information. Eighty cheek dentitions of Asian wild asses (Equus hemionus) from the Southern Gobi (Mongolia) and 61 dentitions of African free ranging donkeys (Equus asinus) from the Emirate Sharjah (United Arab Emirates) were investigated for their …

Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren

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

The data presented here suggest that 18,411 (± 224) khulan inhabit southern Mongolia with a density of 1.4 individuals per 1,000 km² within the 157,525 km² territory of its actual distribution. The Dornogobi province contains the highest number of khulan with a mere 67%, while 20% are found in the Ömnögobi province, 12% are in Djungarian Gobi and only 1% in the Gobi-Altay and Bayankhongor provinces. According to the proportion of foals and yearlings within each aimag, the Dornogobi, Ömnögobi east and Khovd populations have an average reproduction rate.

Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov

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.
