She said this genetic flexibility may be what allows coral reef fishes to swim great distances and disperse widely during these first couple of weeks of life before settling onto a reef where they need to tolerate very different conditions. “Our research shows changes in oxygen uptake rates and gene expression patterns of the various proteins responsible for oxygen transport correspond perfectly to this transition from open ocean to reef habitats,” said Professor Rummer. The shifts in these genes may be what allow anemonefish larvae to transition from being elite athletes in the open ocean to coping with night-time hypoxia on the reef. However, they were most interested in the genes that code for oxygen transport proteins, such as haemoglobin, myoglobin, cytoglobin, and neuroglobin. They found over 4,000 genes were changing during this short window of time. This may also mean they can’t easily leave the reef once they settle.”ĭr Downie, Professor Rummer and the team also examined changes in gene expression patterns over this entire period of early development. “However, oxygen uptake rates decrease midway through the larval phase, meaning larvae may be more efficient and need less energy in preparation for moving to and settling down on coral reefs.

International not only that Downie supports country-specific sites, it is localized into various languages. “The measurements show larval anemonefish initially have very high oxygen uptake rates for their small size and are some of the fastest swimmers that have ever been studied,” said Dr Downie. Downie is updated about once a week with new features, sites supported, etc. The scientists took daily measurements of swimming speeds, oxygen uptake rates, and hypoxia tolerance in newly hatched anemonefish over their entire early development. “This means coral reef fish larvae must rapidly and dramatically shift their physiology over a very short period of time, as the larval phase may only last for 9 days,” says Professor Jodie Rummer, senior author on the study, also based at JCU. “Hypoxia occurs on reefs because corals and plants shift from producing oxygen via photosynthesis during the day to consuming oxygen via respiration at night, therefore creating low oxygen conditions,” said Dr Downie. “At this point, juveniles transition to endure hypoxia – very low oxygen levels that are typical of coral reefs during night-time hours. “Fish larvae living in the open ocean must be elite swimmers to overcome currents, but once settling onto the reef, larvae undergo metamorphosis – like a caterpillar to a butterfly. The app is available for $20 stand-alone or you can get access to it (and many other apps) via Setapp.Dr Adam Downie from the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University led a study examining the development of cinnamon anemonefish as they moved from the open ocean to living on reefs. Downie is an easy-to-use app that I would highly recommend to anyone looking for a simple way to download YouTube videos onto their computer. In addition to YouTube, Downie also has support for more than 1,000 different video sites making it extremely versatile and useful. It worked perfectly and was definitely much easier than me having to use something like Audio Hijack to record the audio coming out of Google Chrome. I also tested Downie by giving it a link to a music video and setting it to only extract the audio as an MP3. I was able to feed the URLs for each episode on YouTube of show (which is called Traveler in case you were curious to check it out) into Downie and away it went. ![]() I decided to try and download a TV show that aired in 2007 on ABC but that I couldn’t for the life of me find anywhere but on YouTube due to the fact it was canceled after one short 8 episode season–and it worked wonderfully. Click on Run Tasks and when done, reboot your computer. ![]() Or lastly, you can use copy and paste – just press Command-O in Downie and you can insert as many links as you want in a single go.Įntering a YouTube video URL to download. move Downie app using Finder from and back to the Applications folder relaunch Safari reboot your computer try rebuilding LaunchServices using OnyX ( select Maintanance > Rebuilding and make sure that LaunchServices is checked. ![]() ![]() Additionally, if you have more links, or links within some text, just drop the whole thing onto Downie – it will scan the text for links. There are a few ways you can have Downie start downloading videos for you, the first way is you can drag a link from any browser either on Downie‘s window, or the icon in the Dock.
