Samoa Study Lends Insight to Heat-Resistant Coral

Survival of the fittest has always been natures way of showcasing the adaptability of organisms and in a world where climate change is ever present it is a known fact our oceans are increasing in temperature. In this latest genetic study done by the Stanford Woods Institute and the Stanford Hopkins Marine Station scientists are using cutting-edge technology and attempting to sequence the genes corals turn off and on to withstand increases in ocean temperatures. In this recent study lead author Daniel Barshis and his team looked in places like Ofu Island in the American Somoa where corals are known to withstand temperature increases as high as 90 degrees fahrenheit in the summer and in low tide. 681x454
Heat-resistant and heat-sensitive corals all react to changes in temperature by turning on or off genes, but what was so interesting about this study was that some coral were found to have already had their heat-resistant genes turned on: The corals genes “changed expression” to repair any damage that was done before the damage had even occurred. The findings imply heat-resistant corals may have a head start in the race to adapt to global climate change.  Stephen Palumbi, co-author of the study, reminds us: “We’re going to put a lot of effort into protecting coral reefs, but what happens if we wake up in 30 years and all our efforts are in vain because those corals have succumbed to climate change?” These genetic markers are now being understood through DNA sequencing to help us further map the sea floor and mark areas like the Ofu Island where heat-resistant corals can be further studied.

13 Non-native Species Introduced to California Waters Through the Aquarium Trade

In a study done by the UC Davis Bodega Marine Laboratory it was found that 13 non-native species of marine fish, seaweed, and snails have been released into California waters.  Citing the preverbal “flush em” technique as a probable cause, the aquarium industry is receiving the bulk of the blame in a report aimed at assessing the potential ecologic and economical impacts of non-native species in Californian waters. The study also found approximately 102 species are being imported everyday through the San Francisco ports causing concern for invasive species that can compete with native species for habitat resources. With recent outbreak concerns of the invasive Lionfish around the world, this study sheds more light onto similar concerns in Californian waters. lion-fish-739346 Susan Williams, lead author, finds in their conclusions: “that a more centralized information and permitting system would benefit the regulators, industry and hobbyists, and enable scientists to collect more information and better assess the risk.” She also recommends to hobbyists: “Aquarium hobbyists can follow some simple practices — like ‘Don’t dump your aquarium’ — to avoid releasing aquarium species into natural water where they can become an expensive and harmful pest.” Contacting your vendor or place of business you purchased said livestock and arranging a return is another method of control she suggested. The oversight she recommends would most definitely limit the amount of livestock imported into the United States and impact the aquarium trade in ways we cannot predict. Funded by the California Ocean Protection Council and California Ocean Science Trust the study comes nearly 13 years after a devastating Caulerpa outbreak in San Diego and is another reminder of how we as hobbyists should exercise caution when choosing, and disposing of, aquarium inhabitants. Read the report here!… More:

Product Review: Cobalt Aquatics Neo-Therm aquarium heater

featuredWhen it comes to fish tank equipment, countless amount of innovations have been implemented in recent years as technology changed and our understanding in keeping marine animals improved. There is however, a group of aquarium devices that hasn’t changed so much in terms of build and functionality. Belonging to such category are aquarium heaters- sure, we’ve seen some improvements in the thermostat designs, build quality and user-friendliness, but at the end of the day most heaters look and perform alike and it comes down to individual models reliability and effectiveness that really matters. After all, the last thing aquarist need is a heater that either fails to keep set temperature or, worst, overheat tank’s water and kill all inhabitants.… More:

Nordic Reef Set to Offer Innovative Marine Products to European Hobbyists

European hobbyist will soon have another aquarium and aquarium accessory manufacturer to consider for their purchases with the announcement that Nordic Reef Shop will be stocking Innovative Marine‘s line of products including the Nuvo Aquarium line, Skyye LED lighting and their newest addition, the Aquagadget line. Screenshot_2013-01-08-23-22-32 Nordic Reef appears to have products in stock and ready to ship, but I can’t help but wonder if there’s more room in the European market with such established companies as Blau Aquaristik and Elos already carving out a huge nitche in the high end aquarium sector. Only time will tell whether or not Innovative Marine’s products will remain overseas, but for now, it’s certainly a leap they should be proud of.… More:

Aussies Deemed unfit to Care for Great Barrier Reef

Australia is currently under extreme scrutiny as guardians of the Great Barrier Reef. With recent findings like the first ever sighting of Acropora eating flatworms and immanent collapse warnings from the UN the GBR will have its fate decided by the United Nations Organization for Education, Science and Culture department. Dr Robin Beaman, a marine researcher from James Cook University: “We should not be so dismissive of the UNESCO concerns about the health of the Great Barrier Reef, to do so is such a parochial response. The World Heritage listing for the Great Barrier Reef, and its continuing health, is vital for the marketing of the area for tourism and the numerous people who derive income from the reef.” great-barrier-reef Criticized for coastal development projects that have weakened the GBR, Australia’s government has now been overstepped by a global body of countries who regards the environment over such things as drilling for oil. UNESCO will decide whether or not the GBR should be deemed a World Heritage site and have oversight greater than what it is currently receiving from the Australian Government. A potential blow to Australia’s conservation reputation these findings paint a picture of the current status of the GBR and Australia’s efforts to preserve it. Read more here! MAJOR FINDINGS FROM UNESCO:
* Rapid increase of coastal developments, including ports infrastructure, of “significant concern”
* Reef lacks overall plan for future sustainable development
* Development and other pressures should be reduced as much as possible to boost reef’s resilience to adapt to climate change
* Warning of reef being listed as “in danger”, if some of the most threatening developments proceed further towards consent
* Warning of “unaddressed concerns” about the protection and management of port and gas industry facilities in Gladstone Harbour and on nearby Curtis Island REPORT RECOMMENDATIONS:
* Australia should not allow any new port developments or associated infrastructure, outside existing port areas, in or adjoining the World Heritage area
* Australian government to complete strategic assessment of the reef before 2015
* Australia must sustain and increase efforts and resources to conserve the reef
* Independent review to be held of the management of Gladstone Harbour… More:

The Sexual Vitality of Gorgonians

Scientists from the University at Buffalo are studying the Gorgonian species Antillogorgia elisabethae to determine its ability to revive after being cropped. A species that is harvested for the skin care industry was studied over a four-year span from the time colonies were cut to when the team returned. The abstract begins saying: “Polyps from female colonies that had previously been cropped produced fewer eggs than those that had not been cropped. The clipped colonies were less likely to have reproductive polyps, and the male colonies that were clipped to 10–15 cm height had fewer reproductive polyps and fewer spermaries per reproductive polyp than unclipped controls that were 30 cm in height.” damagedcoral

 A species known for sexual reproduction, Antillogorgia elisabethae grow in sexually segregated colonies. During spawning events females release eggs that settle on surface tissues of the colony waiting to be fertilized by floating sperm.  The team’s leader Dr. Howard Lasker reflects: “The really interesting finding was that four years later, these colonies were still displaying an effect. They don’t necessarily look damaged anymore, but it takes some time to get back to where they were in terms of reproduction.”  Read more here!… More:

Giant Clam Farm Dive Video of the Philippines

Facebook and YouTube are readily becoming marketing avenues for reef inhabitant vendors. This latest video from a giant clam farm in the Philippines shows how the conservation efforts bred by the aquarium industry can help a species on the verge of extinction bounce back. “Once locally extinct in the Philippines, thousands of clams cultured at Bolinao Marine Laboratory are growing in this shallow-water nursery. These charismatic species are a success story of coral reef restoration biology.”

 The Bolinao Clam Nursery has fields of mature Tridacna gigas, the largest species of clam known to man. Crammed tightly together the clams will benefit from their proximity to each other when they breed and hopefully increase the numbers of this clam throughout Philippine reefs.… More:

Homosexual Tendencies of the Atlantic Mollie Fish

An unexpected finding regarding the sexual behavior of Mollie fish has scientists of the University of Frankfurt intrigued. In a recent study researcher’s found that the mating activities of the male Atlantic Mollie (Poecilia mexicana) include homosexual advances to attract their female mates. The study posits: “Females regularly use social information to choose a mate; e.g. male attractiveness increases after a male has interacted sexually with a female (mate choice copying). Here, we demonstrate that males of the tropical freshwater fish Poecilia mexicana increase their attractiveness to females not only by opposite-sex, but likewise, through same-sex interactions.” pesceomosessuale Male mollies will bite at the genital area of females to assert their right to mate and the study found males will perform this same act upon other male mollies. The sexual tendencies of females observing this behavior were found to increase with not only male-to-female rituals but male-to-male rituals. An adaptation to overcome shortcomings in vibrancy of color or size, males who nip at the genital area of other male mollies will attract more females and theoretically increase their reproductive potential.  Read more here!… More:

Lionfish Attack the Endangered Social Wrasse

The ongoing effort to stifle Lionfish outbreaks in the Caribbean gets some attention in this latest article by Luiz Rocha, curator of ichthyology at the California Academy of Sciences. Writing from Belize where he studies the Social Wrasse Rocha raises new concerns for a species that is currently one of the world’s most endangered reef fish (Halichoeres socialis.) saw-rocha-3-blog480Photos courtesy of Luiz Rocha. This fish is one of the most exquisite of the Wrasse family and is strictly limited to the waters of Pelican Keys. Living in and around mangrove fields its habitat is currently being inundated by local community wastes and now faces the ballooning numbers of a foreign apex predator. Rocha and his team will be collecting Lionfish from the reefs of Belize and examining their stomach contents to better understand the Lionfish’s role as foreign predator. Their findings are limited at the moment as the study began December 15th, however, Rocha remains optimistic in his efforts stating: “It’s up to us to figure out what they are doing to their new home because maybe then we can devise better ways to mitigate their impact on the reef and the social wrasse.” The endeavor to conduct such a study does come with consequences. Check out some of the challenges his team faces when dealing with the poisonous Lionfish after the break! Read more here! Ouch that stings!… More:
