Dew-Bathing In The Atlantic Forest Endemic Robust Woodpecker Campephilus Robustus (Lichtenstein, 1823) (Aves: Picidae), Paul Smith, Kevin P. Johnson

Turkish Journal of Zoology

The bathing behavior of woodpeckers (Picidae) is almost unknown and the paucity of reports of bathing in the family has led to suppositions that they may do so rarely. An unusual observation of the Atlantic Forest endemic Robust Woodpecker Campephilus robustus dew-bathing socially is reported from Paraguay and discussion of its significance follows. Dew-bathing has been reported for a small number of New World bird families and has often been linked to a shortage of water, but has never been previously reported in New World Picidae. Given the environmental conditions in this humid habitat it is considered that dew-bathing in …

Testing For Cryptic Diversity And Inference Of Population Structure In The Cosmopolitan Hoplonemertean Emplectonema Gracile (Nemertea), Paul L. Delaney Iv

Theses and Dissertations

Emplectonema gracile (Johnston 1837) is a hoplonemertean of marine intertidal hard-bottom communities and is distributed throughout the Northern Hemisphere. Although possessing a planktonic larval stage in its life history, the range of such cosmopolitan marine invertebrate species is often explained by cryptic speciation and anthropogenic transport. The purpose of this study is to test for possible cryptic species using mtDNA markers (COI and 16S rDNA) and to investigate population structure in E. gracile over a portion of its geographic range using mtDNA markers and ddRADseq nuclear SNP data. The results of both phylogenetic- and tree-based species delimitation revealed that E. …

Blubber Transcriptome And Proteome Responses To Repeated Adrenocorticotropic Hormone Administration In A Marine Mammal, Jared Deyarmin Jan 2019

Blubber Transcriptome And Proteome Responses To Repeated Adrenocorticotropic Hormone Administration In A Marine Mammal, Jared Deyarmin

University of the Pacific Theses and Dissertations

Chronic physiological stress impacts animal fitness by catabolizing metabolic stores and suppressing reproduction and immunity. This can be especially deleterious for capital breeding carnivores, such as marine mammals, which rely on lipid stores accrued during intensive foraging to sustain prolonged periods of fasting associated with reproduction. Therefore, chronic stress may cause a decrease in fitness in these animals, leading to population declines and potentially detrimental shifts in food web dynamics as a result. However, the impacts and indicators of chronic stress in animals are currently poorly understood. To identify downstream mediators of repeated stress responses in marine mammals, adrenocorticotropic hormone …

Bird Window Strikes On A College Campus: Mortality Estimates And Possible Mitigation, Antarius D. Mclain Jan 2019

Bird Window Strikes On A College Campus: Mortality Estimates And Possible Mitigation, Antarius D. Mclain

College of Graduate Studies: Theses & Dissertations

Understanding the impact that human development has on wildlife populations is essential to preserving biodiversity. Bird populations are a good indicator of anthropogenic threats because they are sensitive to environmental change. Window strikes are a major source of mortality for bird populations. Studies have begun to monitor factors that cause window strikes and estimate the amount of birds killed annually by strikes. However, these estimates can be greatly affected by site dependent variables and scavenging of carcasses. My study addresses this issue by answering four questions: First, how many birds are killed annually on campus? Second, what factors complicate making …

Chemical Composition And In Vitro Rumen Fermentation Of Ensiled Sugar Industry Coproducts, Zohreh Zarnegar, Seyed Hadi Ebrahimi, Abbas Ali Naserian, Reza Valizadeh

Turkish Journal of Veterinary & Animal Sciences

he current study aims to compare sugar beet leaves (SBLs) ensiled with sugar beet pulp (SBP), sugarcane molasses (SM), or rock candy juice (RCJ) using an in vitro gas production technique. Treatments in the first group included 10% SBP (control 1) and control 1 plus 5% SM or RCJ. In the second group, there were 3 treatments, including 20% SBP (control 2) and control 2 plus 10% SM or RCJ. The silages with no added soluble carbohydrate (SC) sources had significantly higher (P < 0.001) pH, buffer value index, and ammonia nitrogen values than the other treatments. However, there was no significant difference between RCJ and SM in their effect on these variables. Adding both levels of SC sources caused an increase in dry matter digestibility compared to those that only included SBL and SBP (P < 0.001). Maximal and rate of gas production from slowly fermentable fraction (a$_{2}$) were significantly greater when the substrate contained 85%, 10%, and 5% SBL, SBP, and SC sources, respectively. Using dried SBP and SC sources for the preservation of fresh SBL is recommended; however, with higher levels of SC, the silage may be at risk of spoilage, and it must be less exposed to air.
