Proportion Of Calves And Adult Muskoxen, Ovibos Moschatus Killed By Gray Wolves, Canis Lupus, In July On Ellesmere Island, L. David Mech 2010 USGS Northern Prairie Wildlife Research Center

Proportion Of Calves And Adult Muskoxen, Ovibos Moschatus Killed By Gray Wolves, Canis Lupus, In July On Ellesmere Island, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Generally Gray Wolves (Canis lupus L., 1758) tend to focus predation on young-of-the-year ungulates during summer, and I hypothesized that wolves preying on Muskoxen (Ovibos moschatus Zimmerman, 1780) in summer would follow that trend. Over 23 July periods observing wolves on Ellesmere Island, Nunavut, Canada, I found that packs of 2-12 adult wolves killed seven calves, one yearling, and five adult muskoxen at distances of 2.9 to 32 km from their current dens and pups. Given a possible bias against finding calves because of their fewer remains, these results do not necessarily refute the hypothesis, but they do …


New Species In The Genus Monoecocesuts (Cestoda: Anoplocephalidae) From Neotropical Rodents (Caviidae And Sigmodontidae), Terry R. Haverkost, Scott Lyell Gardner 2010 University of Nebraska-Lincoln

New Species In The Genus Monoecocesuts (Cestoda: Anoplocephalidae) From Neotropical Rodents (Caviidae And Sigmodontidae), Terry R. Haverkost, Scott Lyell Gardner

Scott L. Gardner Publications

Anoplocephalid cestodes have a worldwide distribution, but relatively few species are known from South American rodents. By examining the collections of the Harold W. Manter Laboratory of Parasitology and the United States National Parasite Collection, 6 new species of Monoecocestus Beddard, 1914, are described, along with a redescription of Monoecocestus mackiewiczi Schmidt and Martin, 1978, based on the type specimens. The discussion includes commentary about uterine development, an important taxonomic character of the family, the vaginal dilation in immature segments (a character of potential taxonomic importance), and the implication of host usage to the evolutionary history and biogeography of species …

Saving Saba Bank: Policy Implications Of Biodiversity Studies, Paul C. Hoetjes, Kent E. Carpenter 2010 Old Dominion University

Saving Saba Bank: Policy Implications Of Biodiversity Studies, Paul C. Hoetjes, Kent E. Carpenter

Biological Sciences Faculty Publications

Saba Bank has always been an area of special importance to the neighboring island of Saba in the Netherlands Antilles. Sabans traditionally fished on the Bank as far back as 1907, but increasing foreign fishing pressures on the Bank in the 1970s and 1980s forced many Saban fishermen out. Concerns were compounded by the suspicion that shipping was also damaging the benthic habitat of the bank. Fishery legislation, enacted in 1996, brought an end to unlicensed fishing and established Coast Guard enforcement on the Bank, but also led to protests from neighboring countries that previously fished on the Bank.Research was …


A Taxonomic Revision Of Orthotrichaceae (Musci) With Contributions To The Biosystematics Of Macromitrium Brid. In Malaysia., Yong Kien Thai 2010 Universiti Malaya

A Taxonomic Revision Of Orthotrichaceae (Musci) With Contributions To The Biosystematics Of Macromitrium Brid. In Malaysia., Yong Kien Thai

Student Works (2010-2019)

Macromitrium (Orthotrichaceae) is a large genus variously divided into infrageneric groups by different authors, resulting in a complex classification which has not included many Malaysian species. This study reviews the taxonomy of Malaysian taxa and extent of morphological variation in relation to the type group. A molecular phylogenetic study was carried out to determine if Malaysian Macromitrium species represented a homogeneous taxonomic grouping. A cladistic analysis of morphological characteristics was attempted for identifying well-defined groups and their key character states. Molecular studies included Maximum Parsimony and Bayesian Inference analyses of two chloroplast DNA regions (rps4 gene and trnL-trnF interspecific region) …


Taxonomy And Biogeography Of Sundaland Gardenia (Rubiaceae)., Low Yee Wen 2010 Universiti Malaya

Taxonomy And Biogeography Of Sundaland Gardenia (Rubiaceae)., Low Yee Wen

Student Works (2010-2019)

In Southeast Asia, the genus Gardenia J.Ellis (Rubiaccae) is poorly understood and documented due to a lack of country revisions, contentious species delimitations and accumulation of poorly identified material in herbaria. This study reviewed the taxonomic history and position of the genus, and revised the taxonomy of Sundaland species (including those of Sumatra. the Malay Peninsula, Java_ Borneo, Palawan and adjacent islands). It includes a survey and cladistic study of morphological characteristics, and phylogenetic ana lyses using two chloroplast regions (atpB-rbcL and trnT-F) and the nuclear ITS region of representative species from Sundaland and adjoining regions. Twelve species are native …


Butterfly Response To Floral Resources At A Heterogeneous Prairie Biofuel Production Site, Benjamin J. Hoksch, Mark C. Myers 2010 University of Northern Iowa

Butterfly Response To Floral Resources At A Heterogeneous Prairie Biofuel Production Site, Benjamin J. Hoksch, Mark C. Myers

Undergraduate Student Work

In the Midwestern USA, current biofuel production systems rely on high input monoculture crops that do little to support biodiversity or protect soil and water resources. The University of Northern Iowa’s Tallgrass Prairie Center is investigating the feasibility of cultivating and harvesting diverse mixes of native prairie vegetation as a sustainable biofuel. In 2009, we established 48 research plots seeded with one of four treatments: 1) switchgrass monoculture, 2) warm-season grass mix (5 species), 3) biomass mix (16 species of grasses and forbs), or 4) prairie mix (32 species of grasses and forbs). We hypothesized that more diverse plant communities …
