What is zonation in ecology? What is rangeland ecology? What is endoparasite migration? What is an ecological overshoot? What is synecology in ecology? What is distribution in ecology? What is social ecology? What is fecundity in ecology?
Explain what the mechanisms of evolution are: 1.) natural selection 2.) non-random mating 3.) mutation 4.) genetic drift 5.) and migration (gene flow). How has natural selection resulted in convergent evolution? Is natural selection the same as adaptive radiation? How does gene flow differ...
Nonetheless, all studies have commonly found that there is no difference in body weight gain between mutant and WT mice upon high-fat diet feeding17,35. The role of HIF-2α in macrophages in obesity is somewhat unclear. High-fat diet-fed macrophage-specific Hif-2α KO mice with the LysM...
Well, despite all this, we believe predator avoidance is a possible explanation because of studies done in freshwater lakes. It turns out there's a correlation between the presence or absence of vertical migration and the presence or absence of fish that find their prey by sight. But what are...
Both figures are approximations as VL is frequently not recognized or not reported12,13. The majority (>90%) of cases occur in just six countries: Bangladesh, India, Nepal, Sudan, Ethiopia and Brazil. Migration, lack of control measures and HIV–VL co-infection (Box 1) are the three ...
In the Anthropocene, the era when the imprint of humans on nature is pervasive across the planet, it is of utmost importance to understand human relationships with other species. The aesthetics of nature, and of species, is one of the values that plays a

Narrator: Listen to part of a lecture in a biology class. 旁白:听一个生物课的讲座。 Professor: Now usually when we talk about birds flying long distances, we're discussing seasonal migration. 教授:现在通常当我们谈论鸟类长距离飞行的时候,我们讨论的就是季节性迁徙。
1、Bird Migration 鸟类的季节性迁徙每年发生两次,似乎包括两个截然不同的阶段:准备阶段和实际开始迁徙阶段。在准备阶段发生两个关键的生理事件:脂肪沉积和迁徙性不安。一些物种(在可能的情况下) 会不间断地飞到的地,这些物种的个体可能...
