Discussion. At 4 days of age, Banana group piglets did not show an immediate preference for the scented arm of the V-maze, but later recognized and were attracted to the scent, as the total time spent in this arm was higher than that spent in the nonscented arm, in agreement with the work of authors such as Morrow-Tesch and McGlone.21 These investigators found that piglets showed greater preference for an odor they contacted at an early age and were able to identify it during the first few hours after birth. Furthermore, our results suggest that as the piglets matured, the bond between Banana group individuals and the banana odor strengthened. This conclusion is based on the preference of a greater number of Banana group piglets to enter the scented arm first and their significantly lower frequency for changing arms. Furthermore, Banana group piglets spent more time in the scented arm than did Control group piglets. The V-maze test at 21 days of age shows that the Banana group piglets, which had ...
In a previous study (Navarro, Miñarro and Simón, 1993) it was observed that 24 hours after administration of haloperidol, this drug still showed antiaggressive effects while immobility effects disappeared. Likewise, other studies have shown prolonged behavioural effects after one moderate dose of the drug (Cohen, Babb, Campbell and Baldessarini, 1988). Typically quoted halflives for neuroleptics, including haloperidol, are approximately 24 hours or less (Baldessarini, 1990); however, there is suggestive evidence that elimination of haloperidol slows with time after dosing (Hubbard, Ganes and Midha, 1987) and that the near terminal elimination half-life may be measured in days rather than hours (Cohen et al, 1988). Recently, Cohen, Tsuneizumi, Baldessarini, Campbell and Babb (1992) have determined the persistence of haloperidol (1 mg/kg ip) in rat plasma and brain tissue, using high pressure liquid cromatography. In this study, the authors found that plasma levels of the drug were not ...
This experiment consisted of 75 different pairs composed of two male adults Xiphophorus helleri meeting each other twice. On the first occasion, one of the fish was familiarized with the meeting place for 3h (resident) while its opponent was familiarized with another aquarium (intruder). Upon dominance of one individual over the other, the pair members were separated and returned to their respective home groups for 168 hours (7 days). After this period of separation, the same pair members were reunited and met while roles had been reversed: the initial resident became the intruder, and the initial intruder was given prior-residency. Individuals in the initial resident role defeated the initial intruder in a significant majority of cases (76%). On their second meeting, the newly established dominance relationship was noted in favour of the new resident in a significant majority of cases (82%), and in a reversed direction as compared to the initially established dominance order. This shows that ...
From Agonistic Behavior to Dominance Hierarchy: An Evolutionary Parable. Picture a wild animal of your morphological choosing. Its solitary and highly territorial. Outside the mating season most of its encounters with conspecifics take the form of agonistic clashes over resources. It has consequently evolved some fairly simple neurocognitive machinery for dealing effectively in these encounters. What it does, briefly put, is first assess the size of any competing conspecific relative to itself and then do one of two things: If the conspecific is clearly bigger, the animal flees; if it is roughly the same size or smaller, the animal attacks and attempts to drive it off.. Now, suppose the habitat of this animal shrinks dramatically, squeezing the entire population into a very limited (but still survivable) space and greatly increasing the encounter rate between individuals. This solitary species, in other words, is forced into a kind of impromptu sociality. Now, under these new conditions a ...
Parasites can influence traits related to the fitness of the host, including host behavior. I studied the behavior of the Ozark zigzag salamander (Plethodon angusticlavius), that was naturally infected with the larval stage of an ectoparasitic mite (Hannemania eltoni) to determine if parasitism was associated with altered behavioral patterns. Experiments were designed to answer three specific questions: (1) Can level of parasitism be detected via chemical cues by conspecifics? (2) Does level of parasitism influence agonistic behavior of males in male-male interactions? and (3) Is parasitism associated with altered foraging behavior of females? In experiment 1, males and females were tested in separate two-choice experiments in the following test conditions: (a) fecal pellet of male with low parasite load versus fecal pellet of male with high parasite load, (b) fecal pellet of male with low parasite load versus control (chemical blank) pellet, and (c) fecal pellet of male with high parasite load versus
Environmental factors. Lack of socialization or unfortunate experiences with strangers during the "sensitive" period of development (3 to 12 weeks of age) sets the stage for fear aggression. Relative isolation from strangers leads to a global mistrust and suspicion of unfamiliar persons, whereas adverse experiences produce more targeted response. Men and children are most likely to be the subjects of dogs fearfulness with respect to of people, probably because of their greater propensity for agonistic behavior toward animals. Although the early period of life provides the most rapid and indelible form of learning, extremely distressing incidents later in life can also result in permanent learning of the regrettable type. In their wisdom, dogs sometimes generalize their learning to include all men or all children, though fearful learning can be as specific as being associated with only men wearing tall hats or men with white beards. A pup that is destined to become fear-aggressive is usually ...
Bone cracking capabilities also independently developed in two lineages of late Cenozoic Canidiae in North America (hesperocyonines and borophagines). Interestingly, both lineages also exhibit a zigzag pattern of crystalline fibers in the enamel which increased the enamels strength. I wonder if any theropods had such an enamel pattern?

Numerous forms of behaviour have been described as aggression , varying in terms of the situations in which they occur, their presumed functions and underlaying physiologies (Moyer, 1968, Brain, 1981). Because attack and defensive/submissive behaviours are intimately related, many scientists prefer to use the term agonistic behaviour to encompass the entire continuum involved in conflict. The agonistic interaction that has been most studied is that of intraspecific aggression between males. Such behaviour is ritualized , in that it seems to involve injury-limiting strategies, and its function seems to be the increasing of the possibility of gaining access to a resource (a mate, territory or social status), closely concerned with reproduction.. The concept of dominance where one animal takes precedence over another is intimately associated with the above type of aggression. Much controversy surrounds the dominance-subordination relationship, although a consensus holds that it is a relationship ...

I laughed out loud at Blairs comments about choreographing my victory dance because I was just thinking about how close I am to doing a victory dance when I happened to log on and read his comment. Im not sure if I should try to do a back flip in the NIH parking lot, especially since Ive never really been coordinated enough before chemo to attempt a back flip. I could do some sort of end zone dance and spike a football as I run laps around my car in front of the building. Do I scream "WOO HOOOOOOOOOOOOO!" as I leave the building or save that for after my CT/PET scan results on August 16th? I feel like celebrating at least this first part because I wont need chemo (hopefully) ever again and Im excited. I know I may have a hospital visit next week to look "forward to," but at least the chemo part is DONE! No more chemo coladas for me and hopefully Priscilla is nothing but a tiny nit and nothing to worry about any more ...

What was the scope of Barack Obamas victory? His 365 electoral votes (the number so far-Missouri remains too close to call) represent a formidable tally, more than double John McCains 162. True, Obamas electoral-vote total as of this writing is smaller than Bill Clintons in either 1992 (370) or 1996 (379). But it is worth remembering that because of Ross Perots third-party candidacies in those years, Clinton did not receive 50 percent of the popular vote in either race-he won 43 percent in 1992 and precisely 49.24 percent four years later, whereas Obama took about 52.6 percent, beating McCain by 6.5 percent. Jimmy Carter won just 297 electoral votes in 1976 and defeated Gerald Ford by only 1.7 million votes out of 80 million cast.1. When measuring victory by some combination of electoral and popular votes, then, one must go back to 1964, when Lyndon Johnson won 61 percent of the popular vote and 486 electoral votes to Barry Goldwaters 52, to find a more impressive Democratic win. Obama ...

I have no strong opinion about the alcohol rule. Personally, I dont drink at work (or work functions) as I have seen the deleterious effects of same. Feels like a liability issue as well.. Im also super-supportive of a harassment policy that prohibits language that is used to harass, be it profanity or not. (case in point, many people dont consider the R word to be an official profanity, but I will object to its casual use every time, as it is pretty terrible).. All that said, I swear in general, because profanity is really interesting. I moderate my language around people who object to it, sure. But I also do things like use words that sound dirty but are not in fact official profanities, or perhaps are marginal. Referring to someone as a turd hurler, for example, skirts the line. I find it an interesting challenge to develop insults that can be applied to a specific person without pulling in old racist / imperialistic / patriarchal (&c.) tropes.. Further, actual semiotic disruption is ...

We identified strong connections between L. dalli social network structure and multiple aspects of reproduction, including male RS. Overall, fewer eggs hatched in high-density social networks (figure 1a), similar to our previous study [36]. We demonstrated that a specific pattern of agonistic interaction was responsible: males were more successful in social networks with low agonistic reciprocity (figure 1b,c). Across species, hierarchies are defined by asymmetrical agonism, directed from dominant to subordinate [17]. Although L. dalli hierarchies were linear, the variation we observed in reciprocity indicates that subordinates can and do displace dominants, an action that reduced, or was reduced by, fitness. Reciprocity was negatively related to HS (figure 1c), specifically, and factor analysis identified a central role for agonism directed at beta females by alpha and gamma females (figure 3a,b). Using different analytical methods, we previously identified a role for these females, suggesting ...
I know it is not polite to brag. However, when you have a special needs child, bragging tends to come with the territory. Especially when your childs prognosis for neurological status and mental capacity are unknown. Marissa has Agenisis of the Corpus Callosum. This means that the piece of her brain that connects the left and right hemispheres and allows them to communicate is missing some parts. At this time in her life, no one can tell us what, if any, effect this diagnosis will have on her future and her ability to learn. It is a wait and see kind of game. It is cause for celebration your special needs child reaches a milestone or accomplishes something you as a parent were not sure they would. Therefore, I choose not to call it bragging. I call it a victory dance. So join me in a little victory dance for Marissa, wont you?. ...
Social learning can be defined as learning influenced by observation of, or interaction with, another animal [30]. It thus encompasses two rather different processes. Learning through social interaction, including social play and agonistic interactions, generally involves the acquisition of social skills. Learning via social information is essential for the acquisition of non-social skills, although it may also be used in the acquisition of social skills (e.g. through eavesdropping: [31]). This second kind of social learning can take different forms of varying complexity, ranging from mechanisms as simple as local or stimulus enhancement to complex forms of imitation (e.g. summarized in [32]). It must be pointed out, however, that most social learning in animals is not direct copying. Indeed, along with a variable involvement of dedicated cognitive mechanisms [33-35], social learning almost invariably includes an important element of individual evaluation [36], and may indeed largely rely on ...

I went in for my P+3 US to confirm that my follicle ruptured. Well it was my lucky day bc they asked me which nurse I wanted and my favorite nice nurse J was there. She does not judge me and she takes her time and explains everything. She said my lining looked great and luteal. I think my follicle ruptured which would be a huge victory. My ovary is covered in junk and I have a large pocket of fluid so it was really hard for her to say 100%. But, I did not see the obvious follicle. Usually I go in and it has grown and will mock me. In fact she said she saw a possible corpus luteum.......Woah!!!!! I have never heard those words before. This is all due to the lupron trigger. This was my first time taking it so I cannot say that it is really working until it happens again. I will take my happy thoughts bc I really needed some today.

In learning genetics, many students misunderstand and misinterpret what "dominance" means. Understanding is easier if students realize that dominance is not a mechanism, but rather a consequence of underlying cellular processes. For example, metabolic pathways are often little affected by changes in enzyme concentration. This means that enzyme-producing alleles usually show complete dominance. For genes producing nonenzymatic proteins such as collagen or hemoglobin, the amount of product matters, and dominance relationships are more complicated. Furthermore, with hemoglobin, dominance can change depending on what aspect of the phenotype is being studied and on the environmental conditions. X-linked genes are a special case, whether enzymatic or not. Because of X-chromosome inactivation, only one X-linked allele can be active in a cell, which means that the concept of dominance cannot be applied at the cellular level. Instead, a type of dominance is demonstrated at the individual level; but even ...
Simulations enabled us to test the relative importance of individual aspects of the melanistic phenotype (such as a mating advantage for melanistic individuals) in facilitating gene flow between host plants. Indeed, the simulations found that the presence of melanistic T. cristinae reduced adaptive differentiation between populations on different hosts and increased rates of inter-host mating (see figure below). These results show how the melanistic phenotype acts as an anti-speciation phenotype, mitigating the effects of divergent selection acting on the stripe phenotype. Moreover, we found that these results were robust to removing individual factors attributed to the melanistic phenotype, such as their mating advantage or their propensity to disperse. The one factor that, when removed from the model, did reduce the anti-speciation effect of melanistic individuals was the genetic architecture of the colour and pattern traits: when we removed dominance relationships among alleles at the ...
In my eyes the problem starts when people dont realize theyre ignoring all the non confrontational polite calming signals directed towards you. If youre doing something theyre not comfortable with the majority of the time theyll let you know well in advance that its not sitting well with them. Subtle signs like; the look away, lick lips, sniff, back away, yawn. If you dont take note at that time, the dog will kick things up a notch and use more overt agonistic signals like; freeze, hairy eyeball, growl, lunge, air snap, or even a pressure bite, barely felt by your skin. If they INHIBIT themselves from a full on bite, puncture and tear causing stitches...I call all those signals being "opinionated ...
Chawke wasnt the only Irishman in the winners circle during the CSI3* Classic at Palgrave Phase 2. Swail had dominated earlier in the week, winning the $36,500 CSI3* Open Welcome, presented by Horseware, on Thursday, May 23, riding Koss van Heiste, a nine-year-old grey Belgian Warmblood gelding owned by Eadaoin Collins. A total of 15 horses had qualified for the jump-off but none could catch Swails winning pace of 37.74 seconds. Canadian Olympian Amy Millar, 42, of Perth, ON, came closest, guiding Ericson, a 10-year-old Dutch Warmblood stallion owned by Millar Brooke Farm Ltd. and Partners, to a second-place finish in a time of 39.10 seconds.. In Saturdays $40,000 CSI3* Table A Speed, presented by Pommies Cider Co., Swail did the seemingly impossible, tying himself for victory with an identical time of 65.54 seconds riding Koss van Heiste and Pin Up de Hus Z, his nine-year-old bay Zangersheide mare (Pilot de Hus x Casall).

Hi Fiona and Tyson, Firstly, I want to say how brave I think Tyson is, and how proud you must be, Fiona, that Tyson has been handling this situation so far. The school will definitely need to be notified of these incidents asap as schools have a zero tolerance policy when it comes to bullying. Step 1 is to ensure the school has the information so they can deal with the child(ren) involved in the bullying. Because you live in Toronto, you might be very interested to hear that the Toronto Argonauts are VERY involved with speaking at schools regarding anti-bullying. Please see this link for their program entitled Huddle Up Bullying Prevention Program http://www.argonauts.ca/page/huddleupOur childrens school was included in a visit last month for an anti-bullying rally in which one of the Toronto Argonauts along with one of the staff came to our school TWICE - once to talk to the kids, and then in the evening to speak to the parents. It was GREAT and the kids and parents loved it! The evening talk ...
