TheEffectsofNiCl2onSpiculeFormation
The Effects of NiCl2on Spicule FormationJessica Ann Billet, Franklin and Marshall, Class of 2000Background and ObjectiveSea urchins exhibit radial holoblastic cleavage, eventually forming a blastula. Shortly after the blastula hatches from the fertilization membrance, the embryo begins gastrulation. Gastrulation begins when the vegetal side of the blastula begins to thicken and flatten. This flat sheet of cells is ca......阅读全文

新疆生态所荒漠植物快速形态调整生态适应意义研究获进展
叶片表面结构及其与水平面的夹角是植物构型的重要成分，能够影响植物对光能和水分的利用。植物通常具有稳定的叶倾角，并不随环境变化而变化。一些荒漠植物能够快速调整叶和细胞形态以避免不利环境条件的伤害，提高植物在恶劣生境中的生存率。 中国科学院新疆生态与地理研究所张元明研究团队在“973项目”和国家自

南京古生物所早期海绵类演化研究获新进展
海绵类存活在地球上已至少五亿四千万年了，是最早出现在显生宙的动物门类之一。但它们的早期演化历史至今仍未完全了解，主要原因在于它们不容易完整地保存成为化石。现今早期海绵演化分类研究多依靠现生物种的分子生物学证据，而最近通过对早期海绵化石骨针结构的研究却得到了令人惊讶的结论。 现今海绵依其骨针
