Lion cubs bred to be shot by foreign hunters
BODY:
Safari operator and environmental writer Ian Michler has exposed a multi million dollar industry in South Africa, where lions are bred in captivity to be shot by trophy hunters
And that the practice is being partly funded by donors who believe they are giving to lion sanctuaries.
EXTENDED BODY:
Thousands of lions in South Africa are being 'bred for the bullet', says a safari operator who has exposed the disturbing facts behind lion hunting in Africa.
Safari operator and environmental writer Ian Michler has exposed the fact that many lion cubs in South Africa are being taken from their mothers and sold for trophy hunting, with the practice being partly funded by people who believed they are donating to lion sanctuaries.
He is the narrator of the new documentary, Blood lions: Cubs to the slaughter, which details how thousands of lions are bred in captivity, packed together in small cages until they are fully grown, then shot by foreign hunters who take them home as a trophy.
Speaking to Nine to Noon this morning, Mr Michler said there were thousands of lions held in captivity like this, three times as many as the 1500 lions living wildly in South Africa.
He said the lions were bred in confined spaces purely for the purposes of trophy hunting.
"They're tame, human-imprinted cats that then get moved into a larger area when the big, brave hunter comes. I have no idea what these trophy hunters tell their friends back home, all I can tell you is these are hand-reared, tame animals, and they are shot in confined areas."
Listen to Kathryn Ryan speak to Ian Michler on Nine to Noon here:
Mr Michler - who works as a safari operator, specialist wilderness guide, consultant and environmental photojournalist - has lived and worked across Africa for the past 25 years.
He said another major issue with the practice of raising lions for hunting led to a lot of inbreeding, especially when the businesses tried to create the coveted white lions.
"This means that in captive conditions, the gene pool is completely contaminated."
Hunting was the most obvious revenue stream, but Mr Michler said the businesses also made money from allowing tourists to pet and play with the animals when they were cubs, offering gap year students opportunities to work on the farms for US$2000 a trip, and shipping off lion bone to Asia, where it was used in traditional medicines.
He said the practice was partly funded by people who thought they were donating to sanctuaries, and said it was a "complete lie".
"It's fraudulent marketing. What I think is happening is the breeders and the hunters and the petters understand now that the media and conservationists like myself and many other people are on to what they are doing. So they are trying more and more to come up with justifications as to why their particular facility is still legitimate."

Lampreys aka 'vampire fish'
BODY:
Lampreys are eel-like jawless fish, related to sharks, that spend their lives in fresh and salt water, and at sea they use their sucker-like mouths to attach to large animals to feed
EXTENDED BODY:
The lamprey twists and writhes as NIWA freshwater scientist Cindy Baker holds its mouth next to the soft skin of her forearm. Then it latches on, using hundreds of small teeth as well as the fleshy sucker that surrounds its small circular mouth. Once it has a good grip Cindy lets go and the eel-like fish just dangles, taking all its own body weight.
Lampreys – or vampire fish as they’re sometimes called – have perfected the art of latching onto large animals at sea, such as fish and whales, and using their sharp teeth to rasp into the flesh to suck out a feed of blood. Cindy doesn't let this particular lamprey linger on her arm for long, before she grabs hold of it firmly and pulls it off with a sucking sound.
But the lamprey has already left its mark: a neat circle of puncture wounds already oozing a little blood. It’s a striking demonstration of how strong and agile New Zealand lampreys can be, as well as how efficient their unusual parasitic feeding style is, and Cindy says they put this to good use when they are migrating.
“They’re amazingly good at jumping out of containers. They have a large sucker mouth that they use to help themselves migrate and they can scale vertical walls. As long as they have a wet surface they’re very adept at climbing up waterfalls and around obstacles in the water.”
Now, in case this sounds like a scary case of ‘coming to a river near you’, we should reassure you and note that this is NOT typical behaviour of a lamprey in freshwater. You will not be attacked by an adult lamprey in a New Zealand stream or river – so, with that reassurance in mind, keep on reading (or listening) to find out why.
While lampreys do have a strong mouth, what they don’t have is any jaws. Along with the fully marine hagfish, they are agnathans, the last two species in an ancient group of jawless animals. And as much as they look like eels they’re more closely related to sharks, skates and rays.
“Lampreys, we believe, have been around for more than 360 million years,” says Cindy. “Which if you think back to the time of the dinosaurs means lampreys were migrating upstream and passing them and carrying on their lifecycle. It’s only been since us humans have intervened that their populations are now starting to decline.”
There is one species of lamprey in New Zealand, the pouched or wide-mouthed lamprey (Geotria australis), which is also found in Australia and South America. There are about 38 species found world-wide - and of these only 18 are parasitic in their feeding style. The most infamous lampreys are the sea lampreys that have become a pest in the Great Lakes system of North America. “You end up with multiple lampreys feeding on each fish in the Great Lakes, and it’s destroying their native fisheries,” says Cindy. This is also where the exaggerated tales of lampreys attacking people come from (and the web is full of such scary stories).
Lampreys are anadromous, which means they are born in freshwater, spend most of their life at sea, and then return to freshwater to spawn. Young lampreys spend about 3-4 years living in the stream or river where they were spawned, hiding amongst the gravel on the stream bottom. They live another three to four years at sea, parasitically feeding on large animals such as fish and whales, and then they return to a stream to spawn.
“Of all the lamprey species the New Zealand species is quite unique in terms of its freshwater breeding and life stage,” says Cindy “Most lamprey species live in freshwater for two to three months before maturing, breeding and dying. Pacific lampreys spend up to a year in freshwater, while our guys spend a year to a year and a half, and during that time they’re not feeding, which is really remarkable.”
During this long period of fasting and gonad development an adult lamprey shrinks to about 70% of the size it was when it returned from sea.
Cindy describes lampreys as ‘mysterious’ and says that we know very little about their basic biology. The NIWA research programme she has been running has focused on locating where the lampreys are spawning, and in testing how lampreys use pheromones, which are chemical signals produced by juvenile and adult lampreys.
Individual lampreys were placed in a 5-metre long flume tank with two parallel channels (a bit like a lamprey lap-pool). Water ran through the flume tank and a control odour was dribbled into one channel and a very dilute pheromone dribbled into the other. The lamprey was then observed remotely to see if it had a preference; each animal was tagged with a small internal PIT tag which was detected by aerials in the flume tank. Lampreys have a single nostril on top of their head and an extremely sensitive sense of smell, and Cindy says the concentrations of pheromones used in the experiments was 5x10-10 (0.0000000005) grams/litre of water (or the equivalent of one teaspoon in 4,000 Olympic size swimming pools).
In October 2013 the researchers found the first lamprey spawning nests ever observed in New Zealand – or the southern hemisphere – in the Okuti River on Banks Peninsula. The researchers found the nest, laid on the underside of a large boulder, by following adults that had been marked with PIT tags the previous year. One nest was being guarded by an adult male, and Cindy suspects this is to do with protecting the developing eggs from eels. This is the first time this guarding behaviour by an adult lamprey has been observed anywhere in the world.
In late 2014 pheromone detectors placed in 12 Auckland streams returned positive results for lampreys in two of them, and a closer search found two juvenile lamprey in the Piha Stream and three in Glen Esk. “They’re not present in huge densities,” says Cindy “but they are definitely there.”
Maori know lampreys as piharau, korokoro or kanakana, and they are prized as a delicacy. There were special traps to catch lamprey in spring, when they are migrating for spawning, although declining numbers of lampreys mean it is not such a common sight on marae dining tables any more. Cindy relied on Maori with good local knowledge of lamprey migrating and breeding behaviour to source the animals used in the pheromone experiments.

Lampreys aka 'vampire fish'
BODY:
Lampreys are eel-like jawless fish, related to sharks, that spend their lives in fresh and salt water, and at sea they use their sucker-like mouths to attach to large animals to feed
EXTENDED BODY:
The lamprey twists and writhes as NIWA freshwater scientist Cindy Baker holds its mouth next to the soft skin of her forearm. Then it latches on, using hundreds of small teeth as well as the fleshy sucker that surrounds its small circular mouth. Once it has a good grip Cindy lets go and the eel-like fish just dangles, taking all its own body weight.
Lampreys – or vampire fish as they’re sometimes called – have perfected the art of latching onto large animals at sea, such as fish and whales, and using their sharp teeth to rasp into the flesh to suck out a feed of blood. Cindy doesn't let this particular lamprey linger on her arm for long, before she grabs hold of it firmly and pulls it off with a sucking sound.
But the lamprey has already left its mark: a neat circle of puncture wounds already oozing a little blood. It’s a striking demonstration of how strong and agile New Zealand lampreys can be, as well as how efficient their unusual parasitic feeding style is, and Cindy says they put this to good use when they are migrating.
“They’re amazingly good at jumping out of containers. They have a large sucker mouth that they use to help themselves migrate and they can scale vertical walls. As long as they have a wet surface they’re very adept at climbing up waterfalls and around obstacles in the water.”
Now, in case this sounds like a scary case of ‘coming to a river near you’, we should reassure you and note that this is NOT typical behaviour of a lamprey in freshwater. You will not be attacked by an adult lamprey in a New Zealand stream or river – so, with that reassurance in mind, keep on reading (or listening) to find out why.
While lampreys do have a strong mouth, what they don’t have is any jaws. Along with the fully marine hagfish, they are agnathans, the last two species in an ancient group of jawless animals. And as much as they look like eels they’re more closely related to sharks, skates and rays.
“Lampreys, we believe, have been around for more than 360 million years,” says Cindy. “Which if you think back to the time of the dinosaurs means lampreys were migrating upstream and passing them and carrying on their lifecycle. It’s only been since us humans have intervened that their populations are now starting to decline.”
There is one species of lamprey in New Zealand, the pouched or wide-mouthed lamprey (Geotria australis), which is also found in Australia and South America. There are about 38 species found world-wide - and of these only 18 are parasitic in their feeding style. The most infamous lampreys are the sea lampreys that have become a pest in the Great Lakes system of North America. “You end up with multiple lampreys feeding on each fish in the Great Lakes, and it’s destroying their native fisheries,” says Cindy. This is also where the exaggerated tales of lampreys attacking people come from (and the web is full of such scary stories).
Lampreys are anadromous, which means they are born in freshwater, spend most of their life at sea, and then return to freshwater to spawn. Young lampreys spend about 3-4 years living in the stream or river where they were spawned, hiding amongst the gravel on the stream bottom. They live another three to four years at sea, parasitically feeding on large animals such as fish and whales, and then they return to a stream to spawn.
“Of all the lamprey species the New Zealand species is quite unique in terms of its freshwater breeding and life stage,” says Cindy “Most lamprey species live in freshwater for two to three months before maturing, breeding and dying. Pacific lampreys spend up to a year in freshwater, while our guys spend a year to a year and a half, and during that time they’re not feeding, which is really remarkable.”
During this long period of fasting and gonad development an adult lamprey shrinks to about 70% of the size it was when it returned from sea.
Cindy describes lampreys as ‘mysterious’ and says that we know very little about their basic biology. The NIWA research programme she has been running has focused on locating where the lampreys are spawning, and in testing how lampreys use pheromones, which are chemical signals produced by juvenile and adult lampreys.
Individual lampreys were placed in a 5-metre long flume tank with two parallel channels (a bit like a lamprey lap-pool). Water ran through the flume tank and a control odour was dribbled into one channel and a very dilute pheromone dribbled into the other. The lamprey was then observed remotely to see if it had a preference; each animal was tagged with a small internal PIT tag which was detected by aerials in the flume tank. Lampreys have a single nostril on top of their head and an extremely sensitive sense of smell, and Cindy says the concentrations of pheromones used in the experiments was 5x10-10 (0.0000000005) grams/litre of water (or the equivalent of one teaspoon in 4,000 Olympic size swimming pools).
In October 2013 the researchers found the first lamprey spawning nests ever observed in New Zealand – or the southern hemisphere – in the Okuti River on Banks Peninsula. The researchers found the nest, laid on the underside of a large boulder, by following adults that had been marked with PIT tags the previous year. One nest was being guarded by an adult male, and Cindy suspects this is to do with protecting the developing eggs from eels. This is the first time this guarding behaviour by an adult lamprey has been observed anywhere in the world.
In late 2014 pheromone detectors placed in 12 Auckland streams returned positive results for lampreys in two of them, and a closer search found two juvenile lamprey in the Piha Stream and three in Glen Esk. “They’re not present in huge densities,” says Cindy “but they are definitely there.”
Maori know lampreys as piharau, korokoro or kanakana, and they are prized as a delicacy. There were special traps to catch lamprey in spring, when they are migrating for spawning, although declining numbers of lampreys mean it is not such a common sight on marae dining tables any more. Cindy relied on Maori with good local knowledge of lamprey migrating and breeding behaviour to source the animals used in the pheromone experiments.

Wetland wanderings in the Whangamarino
BODY:
Alison Ballance joins freshwater fish expert Stella McQueen in one of New Zealand’s largest bogs – the Waikato’s Whangamarino wetland – in search of fernbirds, spotless crake and mudfish
EXTENDED BODY:
Wetlands are difficult places to work. They are - not surprisingly- wet, muddy, hard to walk through and too often surrounded by an unwelcoming band of exotic vegetation such as blackberry and crack willows. And the wildlife that makes its home in wetlands is equally challenging: often small, dark and cryptic.
As part of its Arawai Kakariki wetland programme, the Department of Conservation is carrying out research in three major wetland complexes: Whangamarino wetland in the Waikato, Ō Tū Wharekai in Canterbury, and in New Zealand’s largest wetland, the Awarua-Waituna Wetlands in Southland. One objective is to carry out predator trapping to help protect threatened birds, and another objective is to develop ways of monitoring said birds.
This is where Stella McQueen comes in. Stella is a self-described native fish geek. She is the author of A Photographic Guide to Freshwater Fishes of New Zealand (New Holland 2013) and The New Zealand Native Freshwater Aquarium (Wet Sock Publications 2010), a regular correspondent on matters fishy during Nights with Bryan Crump, and also maintains the NZ Native Fish page on Facebook.
During the summer she works on various freshwater contracts, one of which is the spring-time monitoring of cryptic birds in the Whangamarino wetland. DOC wants to know if its predator trapping, which targets rats and mustelids, is benefiting the local populations of fernbird, spotless crake and bittern. The protocol is to spend five-minutes at pre-determined spots along a series of transect lines at different sites in the swamp, listening for fernbird calls. Then she plays spotless crake calls, in an effort to stimulate any nearby birds to reply. Bitterns are detected using recorders that are programmed to record at various times at dawn, dusk and during the night.
I joined Stella for an afternoon listening for fernbirds and spotless crakes - and we did manage to hear one spotless crake churring, and a pair of fernbirds dueting with each other. Stella had also put out small fish traps, called minnow traps, overnight, and these caught a number of small black mudfish, a threatened Galaxid species which is one of five species of mudfish New Zealand.
Stella says that one of the distinguishing features of New Zealand’s native fish is their lack of scales. The mudfish are also able to survive periods out of the water; they are able to gulp air and absorb it through the lining of their mouth.
Black mudfish are found from the Waikato northwards, and have a threat status of ‘at risk – declining’. As well as declining water quality in the wetland due to nutrient and sediment run-off from surrounding farmland, pest fish are a problem, especially Gambusia (also known as mosquito fish) and koi carp.
Wetlands are some of New Zealand’s most threatened habitats. More than 90% of our wetlands have been drained or filled.
Other wetland stories that have featured on Our Changing World include the ecology of Waituna Lagoon, flipping lakes, and monitoring the quality of stream water flowing into Waituna lagoon.

Stories hidden in rocks
BODY:
In this wrap of the Geoscience Society of New Zealand's annual conference, we explore what rocks tell us about our changing world.
EXTENDED BODY:
For their 2015 conference, the Geoscience Society of New Zealand chose the theme Zealandia in Space and Time, to explore many aspects of how our planet works. From natural hazards to natural resources, and from plate tectonics to climate, geologists are uncovering the stories hidden in rocks.
One of the highlights was research that reveals that Antarctic glaciers have retreated rapidly in the past, and that all it took was a minor climate warming.
A team led by Richard Jones, a postdoctoral research fellow at Victoria University, collected and analysed rocks from different elevations along the Mackay Glacier, which drains the massive East Antarctic Ice Sheet (EAIS).
The EAIS has long been thought more stable than the West Antarctic Ice Sheet, where the melting of several glaciers has now reached the point of no return, according to a NASA study published last year. This research adds evidence that the EAIS is not a sleeping giant, but has in the past responded quickly to warming.
The chemical analysis of the rocks the team collected shows the Mackay Glacier retreated and thinned rapidly about 7000 years ago, and the retreat continued for several centuries.
Richard Jones says the rate of retreat was similar to that seen today in glaciers in West Antarctica, where satellite observations show the ice sheet is thinning in response to a warming ocean, and losing more than 150 cubic kilometres of ice each year.
Quite a few of the outlet glaciers of the Antarctic ice sheet are thinning rapidly and are theorised to undergo massive changes in ice loss.
Andrew Mackintosh, who is part of the research team, says the results provide the first geological evidence for the potential of runaway ice loss in Antarctica, triggered by what scientists describe as marine ice sheet instability.
Before Richard’s study, we had theory about how ice sheets might respond and we had computer models that encapsulate this theory, but we had no direct geological evidence that this had occurred in the past.

First woman to win McKay Hammer
During the conference, the Geoscience Society awards several prizes, including the McKay Hammer for the best publication.
This year’s winner is University of Auckland structural geologist Julie Rowland, better known among colleagues as JR, who is the first woman to win the award in its 59-year history.
The paper she received the award for is the result of research in which she investigated active geothermal areas in the Taupo area to use them as analogues for the deposition of gold in areas such as the Coromandel.
In the Taupo Volcanic Zone we have water that could be 250 degrees Celsius, coming up from depth, and when it’s hot like that it carries with it solutes or dissolved metals and other bits and pieces. And as that water comes up from depth, maybe 6 km down, it cools, its pressure changes, and it may, if the circumstances are right, drop out gold and silver.
She says her overarching interest is in broken rocks.
“I like to understand rocks and how they break under some sort of tectonic forcing. What I really want to get at is how the fluid that I might be interested in – it could be hot water carrying gold, but it could be molten rock or magma – how it moves through the crust, either for the purpose of making a geothermal energy recourse, or a gold deposit, or some sort of hazards application."
Understanding earthquake hazards
Many presentations at the conference focused on earthquake hazards. NIWA marine geologist Phil Barnes presented new insights into the tectonic landscapes of North Canterbury and the structural context of the Canterbury earthquakes.
He says the Canterbury earthquake sequence ignited an extensive geoscience response, focused on charting the crustal structure of north Canterbury.
The active faults in that area are hiding under the Canterbury Plains, so we have to use remote sensing techniques like looking at interpretations of gravity or seismic reflection data. This allows us to look at the structure and faulting of the rocks beneath the Canterbury Plains.
He says the Canterbury earthquakes happened at the further edge of the plate boundary zone in the South Island, a wide faulting zone that extends from Westland to Canterbury and is characterised by what geologists call crustal shortening, “where the region is undergoing compression in a north-west orientation”
“The result of that is that for the last million or two years the north Canterbury region has experienced faults that have become active again in an area where there were very old faults in the basement rocks already. The development of new faults and reactivated faults trough the north Canterbury area led to quite a wide spectrum of active faulting that we now see hidden away under the seafloor and the Canterbury Plains themselves."
Studying rocks under the sea
New Zealand geoscientists are part of the international Ocean Discovery Programme, a major global initiative to explore earth below the sea and to study the history and dynamics of our planet.
GNS Science geologist Stuart Henrys explains how New Zealand will contribute by investigating silent earthquakes under the seafloor east of Gisborne when the ocean drilling ship Joides Resolution arrives in our waters in 2018.
The expedition is expected to last two months, and it will be the first undersea drilling project anywhere in the world aimed specifically at understanding the mechanisms of slow-slip quakes.
Three drill sites up to 1.5km deep are planned: one on the subducting Pacific Plate, another where the plate boundary surfaces at the seafloor, and a third on the overriding plate directly above the area of slow-slip, about 40km east of Gisborne.
Stuart Henrys says silent earthquakes, also known as slow-slip events, are similar to an earthquake in that they involve more rapid than normal movement between two pieces of the earth’s crust along a fault line.
However, in a normal earthquake the slip occurs in a matter of seconds, suddenly releasing seismic energy, whereas slip in a silent earthquake can take weeks or even months to occur.

Conservation biologist from Wellington's Victoria University on the search for the rare and elusive, very bushy-tailed, 'vampire' squirrel which lives in the rainforests of Borneo.
EXTENDED BODY:
There has been a search going on for the rare, elusive, very bushy-tailed and blood thirsty 'vampire' squirrel, which lives in the jungles of Borneo.
Dead deer and chickens have been found nearby with only their hearts and livers eaten, some locals believe the squirrel did it.
Conservation biologist from Victoria University of Wellington Dr. Heiko Wittmer has been on the squirrel's trail.
He talks to Bryan Crump about this mysterious creature and the video he captured of it.
