It is important to seek an understanding of teenagers’ perceptions regarding teenage pregnancy. The purpose of this study was to explore and describe the perceptions of teenagers in Bushbuckridge district in the Limpopo Province, South Africa, towards teenage pregnancy. An explorative qualitative...

Phylogenetic framework for Dioryctria (Lepidoptera: Pyralidae: Phycitinae) based on combined analysis of mitochondrial DNA and morphology
Download2005
Sperling, F. A. H., Du, Y., Roe, A. D.
Coneworms of the genus Dioryctria Zeller are important lepidopterous pests of conifer cones throughout the Holarctic region. Seventy-nine Dioryctria species are currently recognized and arranged into 11 species groups, but a globally unified classification of these species groups has not been...

Background Comparative whole genome analysis of Mammalia can benefit from the addition of more species. The pig is an obvious choice due to its economic and medical importance as well as its evolutionary position in the artiodactyls. Results We have generated ~3.84 million shotgun sequences...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...

Plant Phenotypic Plasticity Belowground: A Phylogenetic Perspective on Root Foraging Trade‐Offs
Download2005
Cahill Jr, J. F., Kembel, S. W.
Many plants proliferate roots in nutrient patches, presumably increasing nutrient uptake and plant fitness. Nutrient heterogeneity has been hypothesized to maintain community diversity because of a trade‐off between the spatial extent over which plants forage (foraging scale) and their ability to...

Population structure and phylogenetic relationships of Ceutorhynchus neglectus (Coleoptera: Curculionidae)
Download2005
Sperling, F. A. H., Dosdall, L. M., Laffin, R. D.
Ceutorhynchus neglectus Blatchley is a weevil that is native to, and widely distributed in, North America. It has life-history characteristics similar to its alien invasive congener, Ceutorhynchus obstrictus (Marsham), the cabbage seedpod weevil. Our study was undertaken to compare the population...

Hurd, T.E., Kloppers, E.L., St. Clair, C.C.
Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their...
