Arctic Arthropod Communities In Habitats Of Differing Shrub Abundance
(Biology, 2012-07-25)
Recent global warming, which has been severe in the Arctic, has caused advancement in the timing of snowmelt and expansion of shrubs into open tundra. Such an altered climate may directly and indirectly (via effects on ...
Bioinformatic Identification Of Small RNA (and Their Targets) In The Testis Of Clawed Frogs (Xenopus And Silurana): Implications For Male Fertility
(Biology, 2012-04-11)
Chapter one sets the stage for this project, which lies somewhere near the intersection of speciation, genome, and reproductive biology. Chapter two identifies miRNA with shared expression profiles (Silurana and Xenopus). ...
Addressing Prey Selection And Predator Fitness: Ingestion By, And Growth Of Ochromonas danica On Multiple Bacterial Prey
(Biology, 2012-04-11)
Nanoflagellates provide an important link in aquatic food webs by consuming bacterial biomass and subsequently providing nutrients to higher trophic levels by becoming prey themselves and regenerating nutrients consumed ...
The Effects Of Mine Land Reclamation Of Herpetofaunal Communities
(Biology, 2012-07-25)
Succession describes the process of community change over time after a disturbance. Understanding these processes allows ecological restoration projects to take advantage of natural community trajectories. Reclamation ...
Targeting Of Site-specific Non-LTR Retrotransposons: Role Of Amino-terminal Domains
(Biology, 2012-04-11)
Restriction-like endonuclease (RLE) bearing non-LTR retrotransposons are site-specificelements that integrate into the genome through target primed reverse transcription (TPRT). RLE-bearing elements have been used as a ...
Characterization Of mocR, A GntR Transcriptional Regulator In Bradyrhizobium japonicum
(Biology, 2012-07-25)
The GntR family is one of the most widely distributed and prolific groups of the helix-turn-helix (HTH) transcription factors. In particular, microorganisms that live in complex, fast-changing environments such as soil ...
Evolutionary Relationships In Some Northern Groups Of The Direct-developing Frog Genus Craugastor (Anura: Craugastoridae)
(Biology, 2012-07-25)
Comparing phylogeographic patterns among vertebrates can give insight into the landscape and ecological determinants of phylogenetic diversity. However, in certain taxonomic groups (e.g., birds and mammals) natural history ...
