Behavior Of A Solitary Sociable Female Bottlenose Dolphin (Tursiops Truncatus) Off The Coast Of Kent, Southeast England, Sonja Eisfeld, Mark P. Simmonds, Laura R. Stansfield
This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited ...
Quality Prevails Over Identity In The Sexually Selected Vocalisations Of An Ageing Mammal, 2010 Queen Mary University of London
Quality Prevails Over Identity In The Sexually Selected Vocalisations Of An Ageing Mammal, Elodie Briefer, Elisabetta Vannoni, Alan G. Mcelligott
Background: Male sexually selected vocalisations generally contain both individuality and quality cues that are crucial in intra- as well as inter-sexual communication. As individuality is a fixed feature whereas male phenotypic quality changes with age, individuality and quality cues may be subjected to different selection pressures over time. Individuality (for example, morphology of the vocal apparatus) and quality (for example, body size and dominance status) can both affect the vocal production mechanism, inducing the same components of vocalisations to convey both kinds of information. In this case, do quality-related changes to the acoustic structure of calls induce a modification of ...
Toward Genuine Rodent Welfare: Response To Reviewer Comments, 2010 Animal Studies Repository
Toward Genuine Rodent Welfare: Response To Reviewer Comments, Jonathan P. Balcombe
I’m grateful to the editors for soliciting critiques of my commentary and for the opportunity to respond. Because one of the respondents (Patterson-Kane, 2010/this issue) does not take issue with the main points of my article, whereas the other (Blanchard, 2010/this issue) does, I focus my remarks here mostly on Blanchard’s critique.
Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio
Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim ...

Turban Snails As Habitat For Foliose Algae: Contrasting Geographical Patterns In Species Richness, 2010 Edith Cowan University
Turban Snails As Habitat For Foliose Algae: Contrasting Geographical Patterns In Species Richness, Thomas Wernberg, Fernando Tuya, Mads Thomsen, Gary Kendrick
ECU Publications Pre. 2011
Understanding patterns of species richness is a major goal for ecologists, especially in space-limited habitats where many organisms live on top of others (epibiosis, e.g. by algae growing on gastropods in marine environments). We tested the hypotheses that species richness of epiflora on the gastropod Turbo torquatus would not differ between regions with similarly rich algal floras, and that epifloral richness would increase with increasing gastropod size. Macroalgal floras of Hamelin Bay (HB), Marmion (M), Jurien Bay (JB) and Kalbarri (K), Western Australia, ranged from ~20 to 40 species reef–1 (JB = HB = M ≥ K). Epiflora on small T ...
Assemblage Turnover And Taxonomic Sufficiency Of Subtidal Macroalgae At Multiplespatial Scales, 2010 University of Western Australia
Assemblage Turnover And Taxonomic Sufficiency Of Subtidal Macroalgae At Multiplespatial Scales, Dan A. Smale, Gary A. Kendrick, Thomas Wernberg
ECU Publications Pre. 2011
Spatial variability in the structure of subtidal macroalgal assemblages in southwest Australia was examined at multiple spatial scales using a three-factor hierarchal design. Spatial extents ranged from metres (between quadrats) to many hundreds of kilometres (between regions), and the study encompassed N2000 km of temperate coastline. In addition, the influence of taxonomic resolution, from species level data to class level, on spatial patterns was investigated to assess the potential evolutionary timescales of the pattern and for developing cost effective regionally applicable surrogates for biodiversity monitoring. Almost 300 species were identified from 14 sites, representing considerable biodiversity and a significant subset ...
Ethylene Receptors Function As Components Of High-Molecular-Mass Protein Complexes In Arabidopsis, 2009 University of Tennessee - Knoxville
Ethylene Receptors Function As Components Of High-Molecular-Mass Protein Complexes In Arabidopsis, Brad Binder, Yi-Feng Chen, Zhiyong Gao, Robert Kerris, Wuyi Wang, G. Schaller
Brad M. Binder
Background The gaseous plant hormone ethylene is perceived in Arabidopsis thaliana by a five-member receptor family composed of ETR1, ERS1, ETR2, ERS2, and EIN4. Methodology/Principal Findings Gel-filtration analysis of ethylene receptors solubilized from Arabidopsis membranes demonstrates that the receptors exist as components of high-molecular-mass protein complexes. The ERS1 protein complex exhibits an ethylene-induced change in size consistent with ligand-mediated nucleation of protein-protein interactions. Deletion analysis supports the participation of multiple domains from ETR1 in formation of the protein complex, and also demonstrates that targeting to and retention of ETR1 at the endoplasmic reticulum only requires the first 147 amino ...

Cell Adhesion Property Affected By Cyclooxygenase And Lipoxygenase: Opto-Electric Approach (With Chang Kyoung Choi, Mugdha Sukhthankar, Chul-Ho Kim, Seong-Ho Lee, Anthony English, Kenneth D. Kihm., Seung Baek
Seung J Baek
Expression of cyclooxygenases (COX) and lipoxygenases (LOX) has been linked to many pathophysiological phenotypes, including cell adhesion. However, many current approaches to measure cellular changes are performed only in a fixed-time point. Since cells dynamically move in conjunction with the cell matrix, there is a pressing need for dynamic or time-dependent methods for the investigation of cell properties. In the presented study, we used stable human colorectal cancer cell lines ectopically expressing COX-1, COX-2, and 15LOX-1, to investigate whether expression of COX-1, COX-2, or 15LOX-1 would affect cell adhesion using our opto-electric methodology. In a fixed-time point experiment, only COX-1- ...

The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, 2009 University of Connecticut
The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, Denise Burchsted, Melinda Daniels, Robert Thorson, Jason Vokoun
Billions of dollars are being spent in the United States to restore rivers to a desired, yet often unknown, reference condition. In lieu of a known reference, practitioners typically assume the paradigm of a connected watercourse. Geological and ecological processes, however, create patchy and discontinuous fluvial systems. One of these processes, dam building by North American beavers (Castor canadensis), generated discontinuities throughout precolonial river systems of northern North America. Under modern conditions, beaver dams create dynamic sequences of ponds and wet meadows among free-flowing segments. One beaver impoundment alone can exceed 1000 meters along the river, flood the valley laterally ...
Sleep From Neuroscience And Islamic Perspectives: Comprehension And Practices Of Muslims With Science Background In Malaysian Education System, Mohd Tumiran
Mohd Amzari Tumiran
Incongruence of sleep activities from the neuroscience perspectives and the Islamic view have resulted in confusion and conflicts in the concept of sleep and related issues among Muslims. This research analyzed sleep from both perspectives, determined the level of comprehension of sleep related concept by Muslims with science background in the Malaysian education system and consequently correlated their understanding to sleep related practices. The need for sleep is a well documented fact from both perspectives. The level of comprehension of sleep from both neuroscience and Islamic perspectives among science teachers and students is low. The findings suggest the importance of ...
Naturally Confused: Consumers’ Perceptions Of All-Natural And Organic Pork Products, 2009 University of Illinois Urbana-Champaign
Naturally Confused: Consumers’ Perceptions Of All-Natural And Organic Pork Products, Katie Abrams
Katie M Abrams
Consumers are bombarded with labels and claims that are intended to address their concerns about how food products are produced, processed, and regulated. Among those are the natural or all-natural claims and the certified organic label. In this study, two focus groups were conducted to explore consumers’ attitudes toward all-natural and organic pork and to gather their reactions to the USDA organic standards for meat, and the policy for natural claims. Results indicated that participants had positive associations with the terms “organic” and “all-natural” with exceptions regarding the trustworthiness of all-natural claims. Participants perceived the “no” labeling theme (no antibiotics ...
Delineation Of Precursors In Murine Spleen That Develop In Contact With Splenic Endothelium To Give Novel Dendritic-Like Cells., 2009 Australian National University
Delineation Of Precursors In Murine Spleen That Develop In Contact With Splenic Endothelium To Give Novel Dendritic-Like Cells., Jonathan Tan, Pravin Periasamy, Helen O'Neill
Hematopoietic cell lineages are best described in terms of distinct progenitors with limited differentiative capacity. To distinguish cell lineages, it is necessary to define progenitors and induce their differentiation in vitro. We previously reported in vitro development of immature dendritic-like cells (DCs) in long-term cultures (LTCs) of murine spleen, and in cocultures of spleen or bone marrow (BM) over splenic endothelial cell lines derived from LTCs. Cells produced are phenotypically distinct CD11b(hi)CD11c(lo)CD8(-)MHC-II(-) cells, tentatively named L-DCs. Here we delineate L-DC progenitors as different from known DC progenitors in BM and DC precursors in spleen. The ...
Not Just How One Feels, But What One Images? The Effects Of Imagery Use On Affective Responses To Moderate Exercise, 2009 University of Wolverhampton
Not Just How One Feels, But What One Images? The Effects Of Imagery Use On Affective Responses To Moderate Exercise, Damian Stanley, Jennifer Cumming
Previous research has highlighted a need for identifying the psychological strategies which best maximize the affective responses to exercise (e.g., Blanchard, Rodgers, & Gauvin, 2004). The present study compared the effects on affective responses of using different imagery types while exercising. Participants (N = 75, mean age = 20.2 years, SD = 1.33) were randomly assigned to 1 of 3 imagery conditions (i.e., enjoyment imagery, energy imagery, or technique imagery). Affect was recorded before and after 20 min of moderate intensity cycle ergometry (50% Heart Rate Reserve) using the Exercise-Induced Feeling Inventory (EFI; Gauvin & Rejeski, 1993) and the Feeling Scale (Hardy & Rejeski, 1989). Controlling for affect reported before the exercise bout, the enjoyment imagery group reported significantly higher levels of postexercise valence than the energy and technique imagery groups and higher revitalization than the technique imagery group. These findings indicate that enjoyment imagery could be used to further improve the affective benefits associated with exercise.
Are We Having Fun Yet? Testing The Effects Of Imagery Use On The Affective And Enjoyment Responses To Acute Moderate Exercise, Damian Stanley, Jennifer Cumming
Objectives The present study investigated whether using imagery during acute moderate exercise evokes more positive affective and enjoyment responses than exercising without an assigned strategy.
Design Laboratory experiment.
Methods Participants (N = 88, mean age = 19.81 years) were randomly allocated to 1 of 4 conditions (enjoyment imagery, energy imagery, technique imagery, or exercise alone). Affect was measured before, during, and after 20 min of moderate intensity (50% of Heart Rate Reserve) cycle ergometry. A single-item measure of enjoyment was developed for use during exercise.
Results Enjoyment and energy imagery brought about significant increases in valence from pre- to postexercise, and ...
A Rapid Direct Solvent Extraction Method For The Extraction Of 2-Dodecylcyclobutanone From Irradiated Ground Beef Patties Using Acetonitrile., Amit Kumar
Amit Kumar, DVM, MS, PhD
The amount of irradiated beef in the U.S. market is growing, and a reliable, rapid method is needed to detect irradiated beef and quantify the irradiation dose. The official analytical method (BS EN 1785 2003) that has been adopted by the European Union is time consuming. The objective of this study was to develop a rapid method for the analysis of 2-dodecylcyclobutanone (2-DCB) in irradiated beef. A 5 g sample of commercially irradiated ground beef patty (90/10) was extracted with n-hexane using a Soxhlet apparatus or with acetonitrile via direct solvent extraction. The Soxhlet hexane extract was evaporated ...
