Video: Last Chance For Magical Mangroves?

Filmed around Bimini Island in the Bahamas this new video highlights both the ecological importance of these vanishing forests and the diverse wildlife that depends on them.

Providing nurseries for fish, protecting coastlines against tropical storms and erosion, storing massive amounts of carbon, and harbouring species found nowhere else, mangrove forests are among the most important ecosystems in the world. It is a sad fact that they are vanishing indeed experts estimate that around 35% were lost in just twenty years (1990 to 2010).

Review: Hydor Magnum 7 Stream Pump

In this review we’ll take a look at Hydor’s Magnum range of stream pumps, and specifically put the Magnum 7 to the test. Boasting an electronic start up system and new technology rotors this range certainly looks impressive at first glance. As fans of the Evolution range from this manufacturer we were keen to find out how their ‘big brothers’ stacked-up.

Well, on paper the performance of the Magnum range appears remarkable Continue reading Review: Hydor Magnum 7 Stream Pump

New Images: SPS Corals In Stereo

Following on from our recent tank update, we thought we’d post some images of a few of the corals we added just before xmas 2012. Having been in the tank for well over a month now we are keeping our fingers crossed that these specimens are now settled, indeed we can already see signs of growth and excellent polyp extension (particularly at night). Continue reading New Images: SPS Corals In Stereo

Mechanics Of Coral Sunscreen Explored

Working under tightly controlled conditions in a laboratory and on the Great Barrier Reef, a team of researchers from the Coral Reef Laboratory of the University of Southampton have produced evidence that the pink and purple chromoproteins evident in certain corals can act as a sunscreen for their symbiotic algae.

Dr Jorg Wiedenmann, Senior Lecturer of Biological Oceanography and Head of the University’s Coral Reef Laboratory, said: “The beautiful pink and purple hues that are produced by the coral host are often evoked by chromoproteins; pigments that are biochemically related to the green fluorescent protein (GFP) of the jellyfish Aequorea victoria. In contrast to their green glowing counterpart, the chromoproteins take up substantial amounts of light, but they don’t re-emit light.”

Offering a better understanding of how corals respond to environmental stress, it is hoped that the discovery may help scientists to predict developments on coral reefs that are exposed to climate change and various other forms of disturbance.

Video: TMC Butterfly Makes Our Heart Flutter

TMC have just uploaded footage of a stunning Chaetodon declevis Marquesan Butterfly. Although considered rare in the trade due to its deep dwelling habits and limited range, we’ve seen a handful of these over the last few years. Whatever the case, its sure to attract quite a price tag and demands a set-up specially tailored to its unique needs. Subscribed, logged-in users can view our own profile and images on this species, along with some 35 other Chaetodon species HERE.

Review: TMC V2 Bio React 500

It’s been quite a while since we did our original unboxing review of this reactor, so we’ve been itching to get it running on our system. Now that we’ve made progress with other areas of the display the time was right to deploy this equipment and we set-to with the final assembly and installation.

We’ve already conveyed our high regard for the construction and simplicity of this reactor and this was confirmed as we got to grips with connecting it up.  Continue reading Review: TMC V2 Bio React 500

The Digital-Reefs Black Tank – Stocking Begins

Well, so much has happened since our last update that it’s hard to know where to start. Actually, if we don’t sit down and take a few moments we’ll probably have even more to add…. so let’s just get cracking! In our last installment, the tank had recently been inoculated with live rock and we’d observed as nutrient levels had stabilised generally. In essence the tank was ‘born’ and we were now custodians of a fully functioning miniature reef ecosystem. Continue reading The Digital-Reefs Black Tank – Stocking Begins

Video: Molluscs Disco Well After Dark

Have a look at this really interesting footage from researchers at the University of California, Berkeley. After filming the scallops at night with an infrared camera,  Lindsey Dougherty and her colleagues noticed that the scallops still rolled their reflective lip even though there was no apparent light to reflect. The team are now investigating the possibility that the mechanism has a previously unknown purpose. Read more via Newscientist.
