Tropical fish in WA Kimberley facing extinction from climate change, researchers say

By Erin Parke

12 July 2015

Entire species of tropical fish could be wiped out by climate change, according to a research team that has spent months carrying out a study in Western Australia’s north.

The team from the University of Melbourne is looking at how sensitive freshwater species are to small increases in water temperatures.

PhD student Matthew Le Feuvre said the results were cause for concern.

“We’re finding a lot of species are living potentially very close to their maximum thermal limit, so these species will be very sensitive should the climate change in the Kimberley,” Mr Le Feuvre said.

“If water temperatures and air temperatures increase by just a degree or two, you could potentially see a lot of species fail to adapt and go extinct as a result, or at least become far more vulnerable.”

The team focussed on 18 species that are found only in the river systems of the Kimberley.

Until now, little research has been done on the river systems, partly because they are located in remote areas accessible only by helicopter or boat.

The University of Melbourne study involved eight months of trekking and camping in some of the most rugged terrain in Australia, to allow researchers to collect specimens.

“We’ll arrive at a beautiful spot in the Kimberley with a ute and a trailer fully loaded with sampling gear and a tinny, and then we basically throw the whole kitchen sink at it,” Le Feuvre said.

“We use a variety of nets, a baited underwater video camera, and we use an electro-fisher, which basically stuns the fish in the water and then you can scoop them out, which is a really useful tool for sampling fish.

“We also use traditional hook and line fishing techniques and also snorkelling, so we use a whole lot of methods at each site for a couple of days.”

The fish were packed into customised eskies for the 4,000 kilometre flight to laboratories at the University of Melbourne.

Testing Begins

In Melbourne, they were put into a flow-rest barometer, to measure the amount of oxygen they consumed as the water temperature was increased in tiny increments.

That is when the sensitivity of the fish was discovered, Mr Le Feuvre said.

“We’ve found that these species basically fail to function above 34 degrees, which is roughly the temp of the water you find in the Drysdale river in the wet season,” he said.

The Kimberley species were also considered to be highly vulnerable because of their unusually limited range.

“The Mitchell Falls Gudgeon [for example] is only found around the Mitchell Falls, so it’s only known for a couple of kilometres upstream from the falls, and a couple of kilometres downstream from the falls,” Mr Le Feuvre said.

“There’s one species from the Drysdale River that’s only been caught once… so it’s a really rare species and we failed to find it in more than eight months of fieldwork.”

It is hoped the work results in some of the species being added to a national register of threatened species.

While 20 per cent of Australian freshwater fish species are currently included on the register, none of the endemic Kimberley species are listed.

Conservation group Environs Kimberley said the research work was groundbreaking.

“So little research has been done in the remote areas of the Kimberley, and there’s so much more work to be done up there,” said Marine Projects Officer Jason Fowler.

“It’s certainly going to help build a case to protect these river systems.”

Australian parrots’ beaks and global warming

Bigger beaks help birds combat global warming

To help them cope with climate change birds are grow[ing] bigger beaks, new research suggests. The scientists, led by Dr Matthew Symonds from Deakin’s Centre for Integrative Ecology in Australia, have discovered a pattern between increased climatic temperatures and an increase in the size of the beaks of parrot species in southern and eastern Australia.

“Birds use their beaks to keep themselves cool. Just as an elephant’s ears help to act as a fan to keep the animal cooler, birds can pump blood to their highly vascularized bills, enabling them to lose excess heat when they get hot,” Dr Symonds said.

The researchers examined 410 bird skins, collected between 1871 and 2008 and located at Museum Victoria, the Queensland Museum, the South Australian Museum and the Australian National Wildlife Collection, Canberra.

They found that four of the five species examined had measurably bigger beaks now than they had in the 19th century.

“In an earlier study we found that birds in hotter climates had bigger beaks than those in cooler climates, which prompted us to look at whether there has been an increase in beak size generally as the climate has got hotter over the past century,” Dr Symonds said.

“We found an increase in beak surface area of between four and 10 per cent, which may not sound like much, but would actually make a huge difference to the birds’ ability to cool down when they are stressed by heat. We have been able to show there has been an increase in the size of the beaks, in line with the increase in the temperature these parts of Australia have experienced over the same time frame.

“However, we can’t yet conclusively rule out the effect of other environmental factors, such as changes in habitat or food availability. This work provides an important basis on which to do more research. The next step will be to expand the research to consider a wider range of species from other regions, and with different kinds of beak shapes and lifestyles.

“Aside from it indicating another way in which climate change is affecting animals, the beak is so intimately tied to a birds’ lifestyle that climate-related changes in beaks may have further ramifications for other aspects of their biology: what kind of food they eat, how they compete with each other and how they reproduce.”

The five native Australian parrot species examined were the mulga parrot (Psephotus varius), gang-gang cockatoo (Callocephalon fimbriatum), red-rumped parrot (Psephotus haematonotus), Australian king parrot (Alisterus scapularis) and crimson rosella (Platycercus elegans). The Australian king parrot was the only species where an increase in beak size was not recorded.

The research, “Climate-related spatial and temporal variation in bill morphology over the past century in Australian parrots”, has been published in this month’s edition of the Journal of Biogeography</em>.

“Paradise Lost” with Lijon EknilangMarshall Islands

29 September 2012

This 15-minute segment was produced by ABC TV’s investigative program “Prime Time,” and aired in December 1990. The piece features Lijon Eknilang, a Marshallese woman who was 8-years old at the time of the U.S.’ largest and dirtiest H-bomb at Bikini in March 1954, a fission-fusion-fission bomb 1,000 times the Hiroshima A-bomb.

Caught in the high-level radioactive fallout downwind from Bikini and the H-bomb [Bravo], Lijon subsequently contracted many radiation-induced disorders along with seven miscarriages leading to her eventual sterility.

Lijon Eknilang died last month after leading a life dedicated to both educating the global community about the inherent dangers of nuclear weapons, and also of working tirelessly for the eventual abolition of nuclear weapons.

Lijon Eknilang will be dearly missed.

Bikini community demands US relocation amid flooding

Tuesday 24th March 2015

A TINY Pacific community forced to evacuate their homes because of US nuclear testing is demanding refuge in the United States.

“We want to relocate to the US,” said Bikini atoll mayor Nishma Jamore at the weekend, as Pacific waters continued to eat away at the small Kili and Ejit islands in the Marshall Islands archipelago.

This 13 September 2013 video is called Climate change impact on the Marshall Islands: One island has all ready gone as sea levels rise.

Mr Jamore heads a community of about 1,000 islanders who have lived in exile on the islands for decades because their original Bikini home remains too radioactive for resettlement.

There were 24 nuclear tests conducted on the atoll in the 1950s, including the largest hydrogen bomb detonation ever conducted by the US.

Unable to return to Bikini, the islanders are now faced with increasing flooding from high tides and storms hitting their tiny island refuges, with waves washing over the islands and wiping out food crops.

“Kili has been repeatedly flooded since 2012 and we’ve asked the Marshall Islands government for help with no response,” said Mr Jamore.

There is also serious concern over a recent attempt by the Marshalls’ parliament, known as the Nitijela, to take authority for Ejit island away from the Bikinians.

This is the second time that the islanders have asked to be resettled in the US because of their plight.

In the 1980s, following an aborted resettlement on Bikini that ended with the islanders exposed to high levels of radiation, they attempted in vain to buy a tract of land on Maui in Hawaii.
