Phylogenetic Patterns of Diversity in Herbivorous Insects

Kaczvinsky, Chloe (2019-11-14)

Herbivorous insects comprise an extraordinary amount of the world’s biodiversity, but we do not fully understand what led to the extensive diversification within this group. Popular hypotheses focus on coevolutionary ...

Phylogenetic treatment and taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae, Mygalomorphae, Theraphosidae) within the United States

Hamilton, Chris A. (2015-07-21)

This systematic study documents the taxonomy, diversity, and distribution of the tarantula spider genus Aphonopelma Pocock, 1901 within the United States. Aphonopelma is a group wherein traditional morphological characters ...

Phylogeny and Biogeography of Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] Based on Chloroplast, Nuclear Sequence and AFLP Molecular Marker Data

Liu, Jiarong (2005-12-15)

Watermelons [Citrullus lanatus (Thunb.) Matsum. & Nakai], together with cucumbers, melons of various sorts, summer squashes, winter squashes and pumpkins are the principal food plants of the gourd family (Cucurbitaceae). ...

Phylogeography and biodiversity of ophiuroids in the Southern Ocean

Galaska, Matthew (2017-06-28)

The Southern Ocean surrounding Antarctica is home to a highly endemic benthic fauna, often attributed to the strong oceanic barrier, the Antarctic Polar front. The Antarctic Polar Front and Antarctic Circumpolar Current ...

Phylogeography and population structure of Antarctic ophiuroids: effects of life history, oceanography and paleoclimatology

Hunter, Rebecca (2009-07-01)

The Antarctic landmass and surrounding continental shelf have been isolated for over 24 million years. Geographic and thermal isolation have resulted in a highly endemic, diverse benthic marine fauna. This fauna has been ...

Physical Activity and Body Composition during the First Two Years of College

Newell, Frank (2011-08-01)

Objective: The effects of vigorous and moderate aerobic and resistance physical activity on changes in body weight, body mass index, body fat %, fat mass, and fat-free mass were examined in two cohorts of males and females ...

Physical and Numerical Modeling of Buoyant Groundwater Plumes

Brakefield, Linzy (2008-05-15)

In coastal states, the injection of treated, relatively fresh, wastewater into deep saline aquifers offers a disposal alternative to ocean outfalls and discharge directly into local waterways. The density contrast causes ...
