Parallel patterns and trends in functional structures in extinct island mammals

Integrative Zoology 2014年第2期9卷 167-182页

作者： Alexandra A.E.VAN DER GEER Naturalis Netherlands Biodiversity Center LeidenNetherlands

Endemic mammalian species on islands are generally known to have followed a different evolutionary pathway than their mainland relatives. General patterns, such as body size trends, have been described regularly. How-ever, most island mammal species are unique and each of them is adapted to a specific local niche as part of an equally specific ecological assemblage. Therefore, comparing island species across taxa, islands and time is in-herently dangerous without understanding the adaptational value of the studied feature in the compared taxa and without taking the ecological setting of the taxa into account. In this contribution, general and recurring patterns are described per taxon. Some features, like body mass change and sturdy limbs, are relatively general, where-as most features, like bone fusions and change of orbital axis, occur only in a very few taxa. Some features are even contradictory, such as brain size and degree of hypsodonty, with each taxon having its own particular de-sign. In conclusion, general patterns are more often than not just trends and need to be applied with caution.

fossil history of Mesozoic weevils （Coleoptera： Curculionoidea）

Insect Science 2012年第6期19卷 683-698页

作者： Andrei A. Legalov Laboratory of Phylogeny and Faunogenesis Institute of Systemafics and Ecology of Animals SB RAS Novosibirsk Russia

The first synopsis of Mesozoic weevils （Curculionoidea： Coleoptera） is pre- sented. Changes of family, genera and species abundance during the Mesozoic revealed three distributional patterns. The Jurassic （Karatau） fauna was dominated by the Nemony- chidae. During the Early Cretaceous （beginning at the Jurassic/Cretaceous border）, the Ithyceridae was the prevalent group with a significant role played by the Nemonychidae. In the Late Cretaceous （Cenomanian and Turonian）, the major groups were the Curculion- idae and Brentidae. Obviously, the change of weevil fauna during this period was due to the expansion of the angiosperms, which provided multiple niches in their vegetative and reproductive organs for weevil development.
