The Biogeography And Nesting Biology Of Anthophora, With A Revision And Phylogeny Of The Anthophora (Micranthophora), Michael C. Orr
The Biogeography And Nesting Biology Of Anthophora, With A Revision And Phylogeny Of The Anthophora (Micranthophora), Michael C. Orr
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bees are necessary pollinators for a vast array of different plants, including many which we rely on for food. In order to grow sufficient crops to feed the world’s growing population, we need to make sure our crops are visited by the most effective possible pollinators. However, this is complicated by the fact that there are over 4,000 bee species in North America, many of which vary in their pollination effectiveness and are difficult to identify. My dissertation’s first two data chapters focus on classifying the species of the xeric solitary bee group Anthophora subgenus Micranthophora, including seven newly …
Inventory Of Gulf Of Mexico Oceanic Fauna Data Including Species, Weight, And Measurements From R/V Point Sur (Cruises Dp03 And Dp04) May-August, 2016, April Cook, Tracey Sutton
Inventory Of Gulf Of Mexico Oceanic Fauna Data Including Species, Weight, And Measurements From R/V Point Sur (Cruises Dp03 And Dp04) May-August, 2016, April Cook, Tracey Sutton
DEEPEND Datasets
This data set includes the biological and environmental data for all of the species collected during the DP03 (May 2016) and DP04 cruises (August 2016). The main gear type used was a 10-m2 Multiple Opening Closing Net and Environmental Sensing System (MOCNESS). The MOCNESS was fitted with 6 nets which were opened according to the following depth scheme: net 0 from the surface to 1500m, net 1 from 1500-1200m, net 2 from 200-1000m, net 3 from 1000-600m, net 4 from 600-200m, and net 5 from 200m to the surface. Two trawls were conducted at each station sampled to capture diel …
Ectoparasitic Mites Of The Genus Gigantolaelaps (Acari: Mesostigmata: Laelapidae) Associated With Small Mammals Of The Genus Nephelomys (Rodentia: Sigmodontinae), Including Two New Species From Peru, Donald D. Gettinger, Scott Lyell Gardner
Ectoparasitic Mites Of The Genus Gigantolaelaps (Acari: Mesostigmata: Laelapidae) Associated With Small Mammals Of The Genus Nephelomys (Rodentia: Sigmodontinae), Including Two New Species From Peru, Donald D. Gettinger, Scott Lyell Gardner
Scott L. Gardner Publications
An extensive survey of small mammals and ectoparasites along an altitudinal transect in the Manu Biodiversity Reserve in Peru found the sigmodontine rodent genus Nephelomys infested by mites of the genus Gigantolaelaps Fonseca, 1939. Two distinct species co-occurred exclusively in the pelage of Nephelomys keaysi, G. inca Fonseca and G. minima n. sp. Nephelomys levipes, which replaces N. keaysi at higher elevations, was infested exclusively with a single new species, G. nebulosa n. sp. In this paper, we formally describe these new mite species, and provide more information on the morphology of G. inca.

Investigating Species Boundaries And Taxonomy In The California Pincushion Plants, Theresa Saunders, Leigh Johnson
Journal of Undergraduate Research
Species in the genus Navarretia are annual wildflowers found almost exclusively in California. The Navarretia atractyloides group consists of just two species, N. atractyloides and N. hamata, that are more similar to each other morphologically than to any other Navarretia species. The most recent taxonomic investigation of these two species distinguishes between them based on bract shape, stamen attachment to the corolla, and whether the style is included and anthers included to slightly exserted from the corolla tube versus style exserted and anthers long exserted (Day, 1993). However, we have noticed that some specimens that seem to be …
Phylogenetics, Biogeography, And Patterns Of Diversification Of Geckosacross The Sunda Shelf With An Emphasis On The Genuscnemaspis (Strauch, 1887), Perry Lee Wood
Theses and Dissertations
In my dissertation I investigate two genera of geckos (Cyrtodactylus and Cnemaspis) that are distributed across Southeast Asia with an emphasis on Cnemaspis. In Chapter 1 I use a multilocus dataset, ancestral area analyses, and molecular clock dating to generate a species level time calibrated phylogeny to test the monophyly of Cyrtodactylus and to identify major biogeographical patterns. I identified that Cyrtodactylus is monophyletic only if the the Sri Lankan genus often recognized as Geckoella is included. The results of the Biogeographical analyses reveal a west to east pattern of diversification. Chapter 2 I use a traditional morphological dataset to …

Biology: Faculty Publications and Other Works
A long-standing view of Indian biodiversity is that while rich in species, there are few endemics or in-situ radiations within the subcontinent. One exception is the Western Ghats biodiversity hotspot, an isolated mountain range with many endemic species. Understanding the origins of the montane-restricted species is crucial to illuminate both taxonomic and environmental history.
Komarekiella Atlantica Gen. Et Sp. Nov. (Nostocaceae, Cyanobacteria): A New Subaerial Taxon From The Atlantic Rainforest And Kauai, Hawaii, Jeffrey R. Johansen, Guilherme Scotta Hentschke, Nicole Pietrasiak, Janaina Rigonato, Marli F. Fiore, Célia Leite Sant’Anna
Komarekiella Atlantica Gen. Et Sp. Nov. (Nostocaceae, Cyanobacteria): A New Subaerial Taxon From The Atlantic Rainforest And Kauai, Hawaii, Jeffrey R. Johansen, Guilherme Scotta Hentschke, Nicole Pietrasiak, Janaina Rigonato, Marli F. Fiore, Célia Leite Sant’Anna
2017 Faculty Bibliography
Six strains of Cyanobacteria sampled in the Brazilian Atlantic rainforest and one strain from Kauai, Hawaii, were studied using morphological and molecular approaches, including 16S rRNA gene phylogenies and 16S–23S ITS secondary structures, and are herein described as Komarekilla atlantica gen. et sp. nov.. Morphologically they are similar to Nostoc, Desmonostoc, Halotia, and Mojavia and indistinguishable from Chlorogloeopsis. The parsimony and Bayesian phylogenies of the 16S rDNA show that these strains are close to nostocacean strains, in strongly supported clades and separated from all other genera. The secondary structures of the 16S–23S ITS were very consistent between strains of K. …
Morphological Variation In The Monardella Odoratissima – Monardella Villosa Complex, Monica Estiandan
Morphological Variation In The Monardella Odoratissima – Monardella Villosa Complex, Monica Estiandan
University of the Pacific Theses and Dissertations
In this study, morphological characters were investigated to better characterize the species boundaries between members of the Monardella odoratissima – M. villosa complex (Lamiaeceae). Traditionally, it has been very difficult to identify and separate members of this complex. Monardella linoides, M. purpurea, and M. sheltonii populations are distributed in the overlapping boundaries of these two species (M. odoratissima and M. villosa) and considered within the complex as well. Previous studies and floral manuals have found that the vegetative plant parts from these five Monardella species intergrade with the other taxa in the complex throughout their distribution in California and in …

From 1999 through 2012, a total of 541 individual rodents (jerboas of the family Dipodidae) were collected from several habitat types, primarily from the Gobi region of Mongolia, and were examined for helminth and protistan parasites. Of those rodents, 25 were identified as Pygeretmus pumilio Kerr, 1792 (Rodentia: Dipodidae), whereas 516 were other species of jerboa from the provinces of Dornogobi, Dundgobi, Omnogobi, Ovorhangai, Bayanhongor, Gobi Altai, and Hovd. During our field work, we collected several cestodes; some of which represented undescribed species, and these new species occurred in 40% of P. pumilio from four separate collecting localities. We designate …
