Phenotypic Plasticity Review (BI 107)

Description:

Biological bet hedging occurs when organisms suffer decreased fitness in their typical conditions in exchange for increased fitness in stressful conditions. Biological bet hedging was originally proposed to explain the observation of a seed bank, or a reservoir of ungerminated seeds in the soil.

For example, an annual plant's fitness is maximized for that year if all of its seeds germinate.

However, if a drought occurs that kills germinated plants, but not ungerminated seeds, plants with seeds. In evolutionary biology, however, bet hedging denotes a risk-spreading strategy displayed by isogenic populations that evolved in unpredictably changing environments. Opposed to other survival strategies, bet hedging evolves because the selection environment changes and favours different phenotypes at different times. Consequently, in bet hedging populations all phenotypes perform differently well at any time, depending on the selection pressures present.

Moreover, bet hedging is the only strategy in which temporal variance of offspring numbers per individual is minimized. In biology phenotypic switching is a common bet-hedging strategy in the face of uncertain environmental conditions. Existing mathematical models often focus on periodically changing environments to determine the optimal phenotypic response.

We focus on the case in which the environment switches randomly between discrete states. Hedge betting is a gambling strategy that is also used in the finance world, where the potential losses of investments are mitigated by other outlays.

Of course, while losses can be reduced, it means any gains are also reduced, due to the outlay on the other parts of the hedge. Hedge betting is popular among professional gamblers, who look for value in a market. Outright sports markets are often a good place to look. Let’s say, for example, you bet 50 on Greece to win Euro at 401. From Wikimedia Commons, the free media repository. Jump to navigation Jump to search.

Biological bet hedging was originally proposed to explain the observation of a seed bank, or a reservoir of ungerminated seeds in the soil.[1] For example, an annual plant's fitness is maximized for that year if all of its seeds germinate.

However, if a drought occurs that kills germinated plants, but not ungerminated seeds, plants with seeds remaining in the seed bank will have a fitness advantage.

You’re just trying to soften the blow of a potential loss. Let’s say you placed a bet on a favorite in a given game or match, but may not be feeling particularly confident in it. Hedging to avoid a loss is a strategy that still results in a net loss, so trying to do so as little as possible is the wisest way to go.

Bookmakers are not lazy, so more often than not it is nearly impossible to find a margin for a guaranteed profit at the same book. There are sometimes loopholes to be found of which you may be able to take advantage, but they are rare and may be difficult to find. In conclusion, hedging your bets is a bit of a last resort type of strategy to help you avoid big-time losses.

Studies on the reproductive biology of leeches have shown considerable variation in life history, with annual or biennial life cycles in many predatory species. In evolutionary biology, bet-hedging refers to a strategy that reduces the variance of reproductive success at the cost of reduced mean reproductive success.

In unpredictably fluctuating environments, bet-hedgers benefit from higher geometric mean fitness despite having lower arithmetic mean fitness than their specialist competitors. We examine the extent to which sexual reproduction can be considered a type of bet-hedging, by clarifying past arguments, examining parallels and differences to evolutionary games and presenting a simple model examining geometric and arithmetic mean payoffs of sex.

Under cultivation, the selective pressures that maintained this strategy were relaxed as humans saved seeds and created predictable microenvironments for seedlings, resulting in homogenous harvests and reliable germination for ancient farmers. Evolutionary Biology, Archaeobotany, Morphometrics. Bet hedging refers to the practice of offsetting one bet with a bet done in the opposite pattern.

Essentially, it is backing and laying the same sports event. With offline bookmakers, this was not permitted, as it effectively wipes out a bookies profit. Also, it made no sense for a bookmaker to have a book full of balancing bets.

Hedging Bets against specific sporting events could be considered double-dipping, as players implement multiple bets on different outcomes for the same matchup. For instance, if players bet on the same two teams in a football match up, then this is hedging a bet. However, there aren’t any limitations to how many bets can be placed on one event with most sportsbooks. For some, this seems that a pointless strategy.

However, many species underwent range expansions during their evolutionary history, and the importance of phenotypic diversity in such scenarios still needs to be understood. In this paper, we develop a theory of bet-hedging for populations colonizing new, unknown environments that fluctuate either in space or time.

In this case, we find that bet-hedging is a more favorable strategy than in well-mixed populations. For slow rates of variation, temporal and spatial fluctuations lead to different outcomes. Bet-hedging naturally emerges within this model, and is robust to evolutionary loss through mutations to both the expression of individual genes, and to the network itself.

This robustness explains an apparent paradox of bet-hedgingwhy does it persist in environments where natural selection necessarily acts to remove it? The structure of the underlying molecular mechanism, itself subject to selection, can slow the evolutionary loss of bet-hedging to ensure a survival mechanism against environmental catastrophes even when they are rare. Biological bet hedging analogous to hedging in finance occurs when organisms suffer decreased fitness in normal conditions in exchange for increased fitne.

Abstract In ecology, species can mitigate their extinction risks in uncertain environments by diversifying individual phenotypes. In spatially fluctuating environments, bet-hedging is favored compared to temporally fluctuating environments.

In the limit of frequent environmental variation, no opportunity for bet-hedging exists, regardless of the nature of the environmental fluctuations. For the same model, bet-hedging is never an advantageous strategy in the well-mixed case, supporting the view that range expansions strongly promote diversification.

Also in biology, such strategies are already known and referred to as "bet-hedging". In the process of evolution, bet-hedging is not the usual way of adapting to the environment, in which carriers of advantageous mutations prevail against other individuals that do not show these mutations. In fact, bet-hedging means that a generation produces offspring that is genetically identical, but differs in the ability to prosper in the current environments Some offspring is optimally adapted to the current environment, while others thrive under completely different conditions.

Furthermore, the bet-hedging genotype differed by nine mutations from the ancestral strain, with which the experiment had been started.

Hedging a bet means placing a bet or bets on a different outcome or outcomes, subsequent to an original bet, in order to create a situation where there is a guaranteed profit whether the original bet wins or loses. For example, say a bet with even odds was placed on the Green Bay Packers to win vs the New England Patriots. Futures Future bets are the perfect opportunity to hedge a bet and limit risk, yet still profit. Quite simply put, a hedge bet becomes more logical as the original futures bet gets closer to winning.
