概括

吃和白的远亲青的肠道微生物组表现出类似的组成,这表明饮食驱动微生物的融合. 这与一些两动物物种宿主进化历史形成鲜明对比.

科学领域:

微生物学微生物学
生态生态学生态生态学
进化生物学进化生物学

背景情况:

脊椎动物的肠道微生物组合往往与特殊的饮食相融合,如叶类或 myrmecophagy.
这种现象已经在哺乳动物和鸟类中记录下来,但在两动物中基本上被忽视了.

研究的目的:

为了研究肠道微生物组的组成趋同在食 (和食) 两动物.
为了比较微生物组的相似性与宿主进化分歧和饮食专业化.

主要方法:

分析了来自五个新热带地区家族的15个anuran物种的肠道微生物组合.
植物遗传学分析,以评估宿主进化和微生物社区结构之间的关系.

主要成果:

在与远距离相关的米尔科法古斯人 (bufonids 和 microhylids) 中显示出显著的肠道微生物群融合.
微生物组的组成有时与宿主进化史有关,如在吃水果的青Xenohyla truncata中所见.
特定的细菌种群如 *Paludibacter*, *Treponema* 和 Rikenellaceae 在虫食物种中占有过多的比例.

结论:

饮食策略,特别是食,是两动物肠道微生物群融合的强有力的驱动因素.
猎物到捕食者的传播和饮食介导的选择可能会塑造这些微生物群落.
这些发现为研究肠道微生物在两动物适应有毒饮食中的作用提供了基础.

Osmoregulation in Insects

Osmoregulation in Insects

Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Diversity of Protists I

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
