在最近的一次科学会议上,一个素未谋面的人看着我的名签说:"哦,你就是那个画漫画的人。"现在,我是一个在自己领域拥有20多年经验的研究人员,并且我希望这就是自己被认可的地方。但在一次偶然的涂鸦像滚雪球一样变成了一张漫画形式的海报之后,我还成为了"那个画漫画的人"。我还在适应这种双重身份。不过,经过一番犹豫之后,我决定接受这两种追求的乐趣——以及它们之间意想不到的联系。

In the canonical version of evolution by gene duplication, one copy is kept unaltered while the other is free to evolve. This process of evolutionary experimentation can persist for millions of years. Since it is so short lived in comparison to the lifetime of the core genes that make up the majority of most genomes, a substantial fraction of the genome and the transcriptome may—in principle—be attributable to what we will refer to as ＂evolutionary transients＂, referring here to both the process and the genes that have gone or are undergoing this process. Using the rice gene set as a test case, we argue that this phenomenon goes a long way towards explaining why there are so many more rice genes than Arabidopsis genes, and why most excess rice genes show low similarity to eudicots.

Crustacean parasites associated with hermit crabs from the western Mediterranean Sea,with first documentation of egg predation by the burrowing barnacle Trypetesa lampas(Cirripedia:Acrothoracica:Trypetesidae)

Parasitic isopods(family Bopyridae)and burrowing barnacles(family Trypetesidae)infesting hermit crabs were investigated from shallow subtidal collections made along the southeastern coast of Spain in 2009.A total of 713 specimens of Clibanarius erythropus(Latreille,1818)and 82 Calcinus tubularis(L.,1767)were *** shells and worm tubes inhabited by hermit crabs were collected by hand while snorkeling and were cracked to determine host species,size,sex and presence of *** species of bopyrid isopods were found on ***:the branchial parasite Bopyrissa fraiseii(Carayon,1943)and the abdominal parasite Parathelges cardonae Codreanu and Codreanu in Codreanu,*** all *** examined,Bopyrissa fraiseii was found on 0.6%of hermit crabs and *** was found on 0.3%.A redescription of *** is provided and the species is documented with light and scanning electron microscopy for the first *** Calcinus tubularis harbored parasitic isopods,but one specimen was parasitized by an unidentified rhizocephalan barnacle of the genus Septosaccus(1.2%).The burrowing barnacle Trypetesa lampas(Hancock,1849)was found associated with both hermit crab species and evidence of predation on host eggs by this barnacle is shown for the first *** lampas was found in 4.2%of the shells *** present study expands our knowledge of the parasite fauna of hermit crabs from the Mediterranean Sea and indicates that additional research is needed to determine the impact of trypetesid egg predators on hermit crab populations.
