Understanding selection for long necks in different taxa

There has been recent discussion about the evolutionary pressures underlying the long necks of extant giraffes and extinct sauropod dinosaurs. [] Key Method We consider the evolution of long necks across a wide range of (both living and extinct) taxa and ask whether there has been a common selective factor or whether each case has a separate explanation. We conclude that in most cases long necks can be explained in terms of foraging requirements, and that alternative explanations in terms of sexual selection…
Long necks enhance and constrain foraging capacity in aquatic vertebrates
A simple model indicated that having the head on an extended neck would allow cormorants to half the energy expenditure that they would expend if their body moved in the way their heads did, likely to lead to greater heat loss though and would seem tenable in slow-swimming species.
Mobility and hydrodynamic implications of the long neck in plesiosaurs
Plesiosaurs are extinct marine reptiles that lived during the Mesozoic, well-known for their unique body plan with two pairs of flippers and an elongated neck. What this long neck was used for is
Giraffe Stature and Neck Elongation: Vigilance as an Evolutionary Mechanism
It is postulated that the wider panorama afforded by an increase in height and longer neck has improved survival via allowing giraffe to browse safely over wider areas, decreasing competition within groups and with other herbivores.
Restoring Maximum Vertical Browsing Reach in Sauropod Dinosaurs

This hypothesis is supported by the dorsally extended articulation of the only known co‐fused sauropod cervicals and is more readily restorable and biologically informative for long necked herbivores.
Evolutionary versatility of the avian neck
Birds possess a cervical spine that may be unique in its versatility among extant vertebrates, one that, since the origin of flight, has adapted to function as a surrogate forelimb in varied ecological niches.
ABSTRACT —Plesiosaurs are an enigmatic, diverse extinct group of Mesozoic marine reptiles well known for their unique body plan with two pairs of flippers and usually an elongated neck. The long neck
Pterosaur dietary hypotheses: a review of ideas and approaches
Pterosaurs are an extinct group of Mesozoic flying reptiles, whose fossil record extends from approximately 210 to 66 million years ago. They were integral components of continental and marginal
The First Description of Dominance Hierarchy in Captive Giraffe: Not Loose and Egalitarian, but Clear and Linear
This study represents the first analysis of the dominance hierarchy in the captive giraffe, and discusses the behavioural flexibility of the social structure in response to monopolisable resources in a captive environment.
An Evolutionary Cascade Model for Sauropod Dinosaur Gigantism - Overview, Update and Tests
This review focuses on the sauropod gigantism ECM, providing an updated version based on the contributions to the PLoS ONE sauropods collection and on other very recent published evidence.


The long necks of sauropods did not evolve primarily through sexual selection
There is no convincing evidence that sexual selection was the primary force driving the evolution of sauropod necks, and the traditional hypothesis that sauro pod necks evolved primarily due to the feeding benefits that they conferred is, by comparison, far better supported.
Winning by a Neck: Sexual Selection in the Evolution of Giraffe
It is concluded that sexual selection has been overlooked as a possible explanation for the giraffe's long neck, and on present evidence it provides a better explanation than one of natural selection via feeding competition.
The energetics of low browsing in sauropods
It is argued that the long neck of the sauropods may have been under positive selection for low foraging (instead of, or as well as, exploitation of high foraging), if this long neck allowed a greater area of food to be exploited from a given position and thus reduced the energetically expensive movement of the whole animal.
Necks for sex: sexual selection as an explanation for sauropod dinosaur neck elongation
Information is used to test the predictions of two competing hypotheses proposed to explain the significance of the long neck of sauropods and it is found more plausible that increases in sauropod neck lengths were driven by sexual selection than by competition for foliage.
Some sauropods raised their necks—evidence for high browsing in Euhelopus zdanskyi
It is demonstrated for Euhelopus as well as for the much larger Brachiosaurus that despite an increase in the metabolic rate, high browsing was worthwhile for a sauropod if resources were far apart.
Sexual selection is not the origin of long necks in giraffes
It is concluded that morphological differences between males and females are minimal, that differences that do exist can be accounted for by the larger final mass of males and that sexual selection is not the origin of a long neck in giraffes.
Extensive population genetic structure in the giraffe
There are at least six genealogically distinct lineages of giraffe in Africa, with little evidence of interbreeding between them, and such extreme genetic subdivision within a large vertebrate with high dispersal capabilities is unprecedented and exceeds that of any other large African mammal.
Discovery of a short-necked sauropod dinosaur from the Late Jurassic period of Patagonia
This taxon indicates that there was a rapid radiation and dispersal of dicraeosaurids in the Late Jurassic of the Southern Hemisphere, after the separation of Gondwana from the northern continents by the late Middle Jurassic.
Winning by a Neck: Tall Giraffes Avoid Competing with Shorter Browsers
It is concluded that giraffes preferentially browse at high levels in the canopy to avoid competition with smaller browsers, providing the first experimental support for the classic evolutionary hypothesis that vertical elongation of the giraffe body is an outcome of competition within the browsing ungulate guild.
Comparative dietary evaluations of an extinct giraffid (Sivatherium hendeyi) (Mammalia, Giraffidae, Sivatheriinae) from Langebaanweg, South Africa (early Pliocene)
The dietary preference of Sivatherium hendeyi, an extinct giraffid from the early Pliocene of South Africa, was investigated by applying three dietary reconstruction tools - hypsodonty, mesowear and microwear, indicating that the dietary preference is most similar to that of seasonal mixed feeders and show no similarities with grazers.
