In the background, a bejeweled mannequin in Egyptian robes and headdress stroked a golden harp as if beckoning the portraits heavenward. Diana and Dodi had died in a high-speed car crash 10 days earlier. But the Harrods window still drew throngs of mourners bearing notes and fresh bouquets. The messages offered impassioned variations on a single theme: Dodi and Diana, star-crossed lovers , united in eternity. Peaceful at last. In the dramatic quest for public sympathy that unfolded after the royal divorce, Diana showed a genius for manipulating the press.

Later, Mohamed Al Fayed drew further enmity after revealing that he had paid prominent Conservative members of Parliament to raise questions relating to his business interests in the House of Commons. Vanity Fair is involved in libel litigation with Mohamed Al Fayed, arising out of a September article.

In July, due to the recent delivery of further defense material, the case was adjourned from its scheduled hearing and is now fixed for September Her mystique rested not only on her glamour and vulnerability but also on her monarchical and aristocratic associations.

Had the Princess actually married Dodi and settled, as some speculated she might, in Paris, she would probably have lost favor, even with the masses. He was seen as someone who lacked the drive—or, more flatteringly, the ruthlessness—to make it on his own.

When his romance with Diana hit the headlines on August 7, Dodi suddenly faced the kind of scrutiny that even members of royal families are ill-prepared to withstand. If Diana was reading the tabloids closely, as she was known to do, she likely learned a lot. She also claimed that he once threatened her with a nine-mm. The biggest splash came in mid-August when a sobbing year-old model named Kelly Fisher sued Dodi after he jilted her to take up with Diana.

She claimed that while Diana was on one Fayed yacht she and Dodi were on another, making love. Understanding Dodi is complicated; he was a chameleon with a tendency to tell tall tales about himself. He had been a rich, lonely child, and his financial dependence on his father stunted him as an adult.

He pursued them with unabashed romanticism, idealized them, and sometimes spurned them. A sense of unreality touched everything Dodi did; in many ways, he was the victim of his own misguided, hopelessly romantic dreams. By , Mohamed and Samira were divorced. The father received custody of his son—according to Muslim custom, as Dodi would explain—and the boy grew up in Alexandria. Mohamed took a Finnish wife, Heini, who bore him four more children. Her second husband died in a car crash at age 45, and her mother, Samiha, died at 51 after a botched face-lift.

For all her heartache, Samira kept her affectionate nature. Dodi disclosed little about his upbringing, but he indicated that he had been cared for largely by servants while his father traveled the world. Most accounts said that Dodi was raised a Muslim, though, oddly enough, he told Suzanne Gregard—his wife for eight months during the s—that he considered himself a Catholic.

Dodi was the stereotypical poor little rich boy, showered with toys, treated to luxurious holidays, but essentially lonely. In his father sent the year-old Dodi—a mediocre student—to Le Rosey, a small Swiss boarding school famous for its unique three-month skiing term in Gstaad.

Dodi left after one year, according to Philippe Gudin, director general of Le Rosey. We do know that at age 19 Dodi enrolled at the Royal Military Academy at Sandhurst, where he took the six-month course from January through June Traci Lind alleged that she and Dodi used nicknames Bruisey and Gippo and that he threatened her with a nine-mm.

Dodi ended his military career after receiving his commission at graduation—the equivalent of a second lieutenant. Gold held court and Dodi joined him most nights, sipping Stolichnayas and smoking Cohibas. He was a good bachelor. Women liked him. Dodi stood about five feet ten, had a soft voice with a slight Middle Eastern accent, curly black hair, expressive light-brown eyes, and a smile offset by a slightly sinister mustache.

And he smelt nice. He loved to laugh. Dodi had been hooked on movies since his mid-teens, when he met Barbara Broccoli, the daughter of the late Albert R. Through her, Mohamed became friendly with Cubby, and eventually agreed to set up a film business with Dodi in Mohamed hired filmmaker Timothy Burrill to run the company.

Incorporated in June , Allied Stars Ltd. By , Burrill had already launched a second project, based on a script brought in by producer David Puttnam about a Jewish boy and a Scottish divinity student who were on the British Olympic team in Dodi would later boast to friends that he had discovered the script and pushed the project.

Dodi came on the set for a couple of days, and he came for some postproduction. He was nice and courteous. Chariots of Fire put Dodi Fayed in a position to be a major player in Hollywood. But nothing happened for three years. Wiener jumped at the project, and Mohamed put up the option money. Dodi contacted his friend Mike Medavoy, who headed Orion Pictures. Orion financed the film and refunded the development costs to Mohamed. Wiener could have taught Dodi the nuts and bolts of film production.

But, as quickly became clear, Dodi lacked the desire necessary to see a film through all the difficult stages of budgeting and production. Instead of arriving for rehearsals at seven a. It would have been a way for him to learn. That was kind of it, I hate to say. He was marginal. There was no evil there, just keeping up a particular image that you would love to be.

Dodi—in his 30s by now—had never outgrown his dependence on his strong-willed father, and this he found to be emotionally and professionally crippling. Any son of such a formidable figure must work doubly hard to prove himself, but Dodi never did. Those who knew father and son believe that Mohamed Al Fayed loved Dodi and wanted the best for him.

Dodi was encouraged to fly and then not allowed to. Unable to make any independent decisions, Dodi never fully experienced the personal or professional challenges of adulthood. He was remarkably sheltered. On the surface, Dodi was a dutiful son. Dodi was rarely known to criticize his father. His occasional sullenness may have stemmed from what some saw as inconsistency on the part of Mohamed. That kept Dodi off-balance.

Mohamed was the patriarch of the family, and it was difficult because Dodi never knew how his father would react. When confronted, Dodi would usually apologize and promise payment. If he wrote a check, however, it might well bounce. Dodi had invited Riva as his guest, and then Riva had been presented with the bill.

Only when Riva got fierce with him did Dodi hand over the money—in cash. Other creditors walked bitterly away. During the s, Dodi became part of the jet-set drug scene. I was there when the kilo was around, when the cokeheads went into the bedroom. That was part of his low self-esteem. He loved to buy, to give, to provide. As his guests sat down, Dodi put a huge white truffle in the middle of the table. While various guests tried to shave it, the truffle rolled around the table, sending everyone into paroxysms of laughter.

He said he had bought a foot luxury coach from a rock band and was having it driven to Canada from Oklahoma. Actually it was rented. Beginning in the 70s, Dodi began collecting expensive cars, which reportedly included a Rolls-Royce and five Ferraris. His passion for Italian autos was so intense that in Mohamed bought Modena Engineering, a Ferrari dealership outside London, and made Dodi a director. His Park Lane apartment featured a collection of baseball caps, and he was obsessed with military memorabilia.

He used a family yacht, the Cujo, which was a converted U. Coast Guard cutter that sometimes flew a skull-and-crossbones flag. He rarely read a book and expressed few opinions or interesting ideas.

Dodi was fanatically concerned with personal security. Self-importance was clearly a factor, but Dodi seemed to have genuine fear. Wherever he went, Dodi would insist on having one or more bodyguards and a backup security car in tow. I just want someone to be there for me, to make me feel safe and secure. One of the most disconcerting aspects of Dodi was his tendency to exaggerate the extent of his wealth and privilege. When he rented a house, he would say he owned it. He wanted to impress people.

You felt that if you told him off he would burst into tears. In his adult years, Dodi tried to get to know the mother he had seen so seldom, calling her frequently.

In the form of notations, it can be expressed as. The above relationship is disclosed by the behaviour of income. Full employment growth, the actual growth rate of G must equal Gw, the warranted rate of growth that would give steady advance to the economy, and C the actual capital goods must equal Cr the required capital goods for steady growth.

Although these systems are well studied, there is little evidence of the existence of morphs that have diverged to utilize resources in the remaining principal lake habitat, the profundal zone.

We hypothesized that morphs in such trimorphic systems would have a morphology adapted to one of the principal lake habitats littoral, pelagic or profundal niches.

Most whitefish populations in the study area are formed by a single monomorphic whitefish morph, and we further hypothesized that these populations should display intermediate morphotypes and niche utilization.

We suggest that the ecological processes acting in the trimorphic lakes are similar to each other, and are driving the adaptive evolution of whitefish morphs, possibly leading to the formation of new species. Understanding what processes drive and maintain adaptive radiation is a central question in evolutionary ecology.

A general pattern has been reported from a series of adaptive radiations where divergence in the feeding apparatus is correlated with a specific trophic niche Price Bernatchez noted that the whitefish species complex potentially fulfils the four detection criteria of adaptive radiation, i.

The common ancestry criterion is supported by phylogeographic studies indicating that whitefish populations in northern Fennoscandian i. Here, use of the third major niche in lakes i. Whitefish morphs and gill raker shape in trimorphic lakes.

Relative body size in the figure reflects the average size differences observed in study lakes. As such, the exploitation of the principal lake habitats littoral, pelagic and profundal is likely to be reflected in isotopic values of different individuals. Due to the close association between morphology and trophic ecology, it is likely that any trophic specialism would also be reflected through general morphological adaptations to a particular niche.

We suggest that the DR and SSR forms represent specialist whitefish morphs and therefore expected to see repeated patterns of resource segregation between morphs in trimorphic lakes.

Here, planktivory represented an advantageous feeding strategy in terms of both increased consumption and growth rates in several different whitefish populations. The increased growth rate associated with zooplanktivory may reflect the greater energetic return of zooplankton relative to alternative, e. We also expected to find evidence of reduced ecological and morphological variation in LSR whitefish from trimorphic lakes, due to ecological character displacement due to competitive interactions with the specialist whitefish morphs.

Whitefish were collected from four oligotrophic subarctic lakes in Finnish Lapland Table S1. Kilpis is also located at a higher altitude than the other lakes. Temperature and oxygen conditions in the three principal habitats, i. Putative prey samples were collected from each study lake for inclusion in stable isotope mixing models.

Gillrakers were counted from the first left arch under a binocular microscope and stomachs were removed for diet analysis. Prey items were identified and the relative contribution of each food category to the diet of individual whitefish was estimated using the points method Hynes Niche overlap values range from 0 complete niche segregation to 1 complete niche overlap. In this case, B can vary from 1 a single food category to 10 equal representation of all 10 food categories.

Here B can vary between 1 use of a single habitat type to 3 equal use of all three habitats. A small sample of dorsal muscle tissue was excised from each whitefish.

We then examined individual consumption patterns. Length comparisons were conducted using log 10 transformed data, but untransformed lengths are given here for clarity. There was a consistent size hierarchy between the morphs Fig. Phenotypic traits of whitefish morphs and respective foraging environments. Whitefish habitat use varied in the study lakes Fig. In trimorphic lakes, the different morphs showed high levels of habitat fidelity: DR whitefish were mainly captured from pelagic, LSR whitefish from littoral, and SSR whitefish from profundal habitats Fig.

In monomorphic lakes, LSR fish were caught either in all habitats equally Kilpis or predominantly in littoral and profundal habitats Vuontis. In contrast, LSR whitefish from monomorphic lakes used all habitat types indicating the lack of any association between phenotype and environment, showing increased habitat niche width values Fig.

Niche segregation was clear in polymorphic lakes: DR whitefish were pelagic planktivores, SSR whitefish were profundal benthivores and LSR whitefish were littoral benthivores Fig. Dashed lines join morphs found in the trimorphic lakes. Principal energy sources for whitefish morphs estimated with isotope mixing model SIAR b.

The results of the isotope mixing model SIAR revealed marked and repeated differences in assimilation patterns in LSR whitefish from monomorphic and trimorphic lakes Fig. We examined fish shape as a means of distinguishing between whitefish morphs and to also compare these differences with measures of niche utilization such as diet, habitat and SIA.

The lower row 5d—f presents correlations between mean gill raker count and the same niche parameters. Dashed lines join morphs found sympatrically in the trimorphic lakes. The profundal morph was most distinct, both in terms of both ecology and morphology.

The differences in diet, morphology and habitats use of of LSR whitefish in the two lake types suggest that LSR whitefish show ecological character displacement when found sympatry with the more specialized whitefish morphs.

To our knowledge, this study provides the first evidence of divergence by a polymorphic fish to the major available habitats i. In our study, niche overlap in sympatric morphs was extremely low in terms of habitat and diet. Monomorphic LSR whitefish expanded their niche to utilize all habitat types, but contrary to expectations Roughgarden ; Bolnick actually showed a more restricted diet, consuming more zooplankton prey.

In the Galapagos Islands, specialized finch species segregate available resources in sympatry, but when found in allopatry individual species are able to expand their niche Grant Our work extends these patterns, where monomorphic LSR whitefish had intermediate niche utilization, whereas adaptive divergence to littoral, pelagic and profundal was evident in trimorphic lakes. A crucial question in studies of adaptive radiation is the status of the common ancestor Schluter The ecomorphology of monomorphic LSR whitefish might reflect the fundamental niche of whitefish, whilst that of trimorphic LSR whitefish represents adaptation to a realized niche Hutchinson , where these fish are subject to competition from planktivorous DR whitefish morph.

This permits selective consumption of prey, as indicated by a reduced niche breadth, increased consumption of pelagic zooplankton, ontogenetic diet shifts exploiting optimal prey resources in both pelagic and benthic habitats and an intermediate morphology.

However, predation alone is unlikely to drive morph divergence, whilst resource availability represents a more likely explanation of divergence. Three of the study lakes were colonized by whitefish following glacial retreat along a similar timeframe c. In the case of Kilpis, prey resource limitation combined with a different colonization history probably represent the most likely reasons for a lack of specialized pelagic and profundal whitefish morphs.

The clustering of morphs across trimorphic lakes in the DFA either indicates similar morphological divergence in the different lakes e. In contrast, monomorphic LSR whitefish did not cluster with their counterparts from trimorphic lakes. The results of the shape analysis indicated an intermediate shape between LSR and DR whitefish, most likely reflecting adaptive morphology to generalized niche utilization in a particular lake in the absence of resource competition from specialized morphs.

However the use of isotope mixing models revealed that these were largely of a littoral origin c. Gibson All of these classic vertebrate model studies were able to directly or indirectly show the fitness consequences of morphological divergence.

However, our results are correlative, and the contribution of morphological variation on the fitness of morphs in the different major niches needs to be tested experimentally. In this study, we have described a spectacular level of ecomorphological divergence within a single species comparable to that typically associated with different biological species. This suggests significant genetic differences may exist between the sympatric morphs described here. Genetic studies are underway to examine the ancestral origin mtDNA and level of reproductive isolation nDNA in these populations.
