Predators drive Nemo‘s relationship with an unlikely friend

November 28, 2018

Predators have been identified as the shaping force behind mutually beneficial relationships between species such as clownfish and anemones.

The finding results from a University of Queensland and Deakin University-led study.

UQ School of Biological Sciences researcher and Australian-American Fulbright Scholar Dr William Feeney said the research aimed to understand the origin of such relationships, known as interspecies mutualisms, which are extremely common in nature.

Clownfish — like Nemo from Finding Nemo — and anemones are a great example of this type of relationship,” he said.

“Clownfish live in and around anemones, helping drive off the anemone‘s predators and providing it with food, while in exchange the anemone provides protection with its stinging tentacles.

Clownfish have evolved to resist the stings of the anemone, so it ends up being a very beneficial relationship for both species.”

The researchers said the study helped explain how natural selection had shaped global patterns of biological diversity.

“We tested and confirmed a very basic and intuitive — but logistically difficult — idea in evolutionary ecology,” Dr Feeney said.

“In a nutshell, we were looking to find out whether external pressures, such as predators, can explain the repeated evolution of these kinds of mutually beneficial partnerships.

The research combined genetic analysis with field experiments in French Polynesia to build a better understanding of fish-anemone mutualism dynamics.

Deakin University Centre for Integrative Ecology Research Fellow Dr Rohan Brooker said the team found that fish-anemone mutualisms had evolved at least 55 times across 16 fish families over the past 60 million years.

“This is much more common that previously thought. Over a quarter of coral reef-associated fish families have at least one species that associates with anemones,” Dr Brooker said.

“Our results suggest that the risk of predation has selected these relationships, and that partnerships with anemones primarily benefit smaller fishes.

“Overall, this study suggests that predation can explain the independent evolution of cooperative behaviours between species, and that this evolutionary pattern could apply globally.

“If you can’t find Nemo, it might be a good idea to go rummaging through the tentacles of his anemone friends.”

The study is published in Ecology Letters.

Lies on French Polynesia nuclear bombs admitted

President of French Polynesia admits lies about nuclear testing

President Fritch of French Polynesia has acknowledged in the parliament in Tahiti that the population has been lied to for 30 years about the dangers of the nuclear tests that were held there. Between 1960 and 1996, France held 193 tests with atomic bombs in the overseas territory in the South Pacific.

The images of the mushroom cloud that rose above the Mururoa atoll were increasingly leading to international protests. In 2010, the French government released hundreds of millions of euros to compensate the residents of French Polynesia. The money was also destined for Algeria, where nuclear tests were also held.

“I can not be surprised that I have been called a liar for thirty years, we lied to the people that the nuclear tests were clean. We lied”, was the statement by President Edouard Fritch. Unknown is what brought Fritch to this confession.

On request, the United States news agency AP received no response from the French government to the statements by Fritch.

Radioactive radiation

The whistleblower Bruno Barrillot, who died last year, revealed that thyroid cancer and leukemia occur excessively among the 280,000 inhabitants of French Polynesia.

President Hollande visited French Polynesia two years ago. He acknowledged on that occasion that the nuclear tests had a harmful effect on human health and the environment. But he also praised the contribution that French Polynesia made to the fact that France became an international nuclear power.

Three years earlier, French newspapers reported on the basis of official documents released that the nuclear tests were much more harmful than the authorities had admitted.

Tahiti, the most famous Polynesian island that is often depicted on the paintings of Paul Gauguin, was exposed to radioactive radiation 500 times as high as the maximum permitted level.

‘Nemo’ fish threatened by global warming

This video is about orange-fin clownfish, aka orange-fin anemonefish.

Ocellaris clownfish became famous by the film Finding Nemo.

However, this species, and its clownfish (or anemonefish) relatives are now threatened by global warming. Though the fish themselves can stand warmer ocean water, the sea anemones on which they depend cannot.

As shown by research about orange-fin anemonefish (Amphiprion chrysopterus) in Moorea, French Polynesia; from Nature:

Cascading effects of thermally-induced anemone bleaching on associated anemonefish hormonal stress response and reproduction

10 October 2017


Organisms can behaviorally, physiologically, and morphologically adjust to environmental variation via integrative hormonal mechanisms, ultimately allowing animals to cope with environmental change. The stress response to environmental and social changes commonly promotes survival at the expense of reproduction. However, despite climate change impacts on population declines and diversity loss, few studies have attributed hormonal stress responses, or their regulatory effects, to climate change in the wild. Here, we report hormonal and fitness responses of individual wild fish to a recent large-scale sea warming event that caused widespread bleaching on coral reefs.

This 14-month monitoring study shows a strong correlation between anemone bleaching (zooxanthellae loss), anemonefish stress response, and reproductive hormones that decreased fecundity by 73%. These findings suggest that hormone stress responses play a crucial role in changes to population demography following climate change and plasticity in hormonal responsiveness may be a key mechanism enabling individual acclimation to climate change.

2017 brings hope for Pacific birds

By Mike Britton, 31 Dec 2016

A new year always brings new hope – but 2017 is a big one for conservation in the Pacific. The last big leap forward in 2015 was the restoration of the islands of Acteon and Gambier in French Polynesia. In 2017 we are on the countdown for the next big step forward, the restoration of up to 18 islands of the Marquesas and at Rapa, again in French Polynesia. In January a team including BirdLife French Polynesian partner, SOP (Société d’Ornithologie de Polynésie) Manu, BirdLife Invasives Programme staff and Island Conservation will head to the Marquesas to begin the all-important step of assessing the current state of nature on the Islands, the technical issues associated with a restoration programme and continuing consultation with the local people. This work is being funded by the David and Lucile Packard Foundation. The Marquesas is one of the most important archipelagos for bird conservation in the world. It is home to 22 species of seabird including three globally threatened (Tahiti Petrel, Phoenix Petrel, Polynesian Storm-Petrel) and at least two globally threatened land birds (Marquesas Ground-Dove, Marquesas Monarch).

Restoring the nine satellite islets around Rapa, which is the eastern most island of the Austral Islands in French Polynesia, is the other half of this ambitious project. Financial support for the actual restoration has been secured and this will be another major step forward for nature in early 2018. These islands are home to an assemblage of seabirds unlike those found elsewhere in French Polynesia with eleven species, seven of which are petrels and shearwaters including an endemic form of the White-bellied storm petrel.

Towards the middle of 2017 a further attempt will be made to find the nesting sites of the elusive Beck’s Petrel. The 2016 expedition saw birds but was unable to catch any on the water to enable transmitters to be attached to allow them to be followed home. After a review of methodology the team is quietly confident they can succeed.

Another even more elusive bird is the Fiji Petrel which only nests on Gau Island in Fiji. Funds are being sought to allow a last ditch attempt to find the actual nesting site so that they can be protected from predators. This project was set back when one of the petrel locator dogs died a few months back and support is urgently needed if this critically endangered species is the be saved.

Two other critically endangered species in French Polynesia are the Fatu Hiva and Tahiti Monarch. The Fatu Hiva Monarch is not as well-known as its cousin, the Tahiti Monarch but is existence is even more threatened. It lives on Fatu Hiva, a remote island which is part of the Marquesas Archipelago, 1500 km from Tahiti. There are now just 25 adults left in the world and there are only 5 fertile pairs. Its survival is totally based on controlling predator threats to the birds and nests in the valleys where it lives. This bird depends almost totally on BirdLife Partner SOP Manu working with the local community. The current aim is to stablise the population but that does mean maintaining a long term predator control programme and habitat restoration. The future for the Tahiti Monarch seems a little more secure with the ideal being to establish a second population on an island with less predator danger! The European Union through its Best 2 programme is funding some of this work but it is a major challenge.

Empowering local people in all Pacific countries is the way to give nature a truly sustainable future. Last year extreme climatic evens like Cyclone Winston wreaked havoc with the local communities that work with BirdLife Partners. The aim is to help these communities rebuild and look for ways in which BirdLife and its partners can make a real difference in their lives and for the natural treasures for which they are the guardians

Across the Pacific BirdLife partners are fully engaged being the champions of nature. These are just some of the special projects. We have the solutions to stop extinctions and support local communities. We just need your support. Help with a donation.

Just two years after ambitious efforts by a team of international conservation organisations to rid French Polynesia’s Acteon & Gambier island groups of invasive mammals began, five of six targeted islands are now confirmed as predator-free—a ground-breaking one thousand hectares in total. Early signs already indicate that rare birds found nowhere else in the world (endemic) and other native plants and animals are recovering as the remote islands return to their former glory: here.

How we’re going to save the little paradise in the Pacific. The rare native wildlife of a remote island has retreated to a precarious existence on vertical cliffs. An urgent project supported by the 2017 Birdfair is leading the counter-attack against invasive species to save the “little planet” of Rapa Iti: here.

In 1800, French explorer Nicolas Baudin led an important scientific expedition to Tenerife, Mauritius, Australia, Timor and South Africa. He returned with hundreds of exotic bird species. PhD candidate Justin Jansen reconstructed this ‘catch’ in a weighty book and talked to us about the wonderful finds: here.

A small window of opportunity to save the unique birds of Rapa

By Steve Cranwell, 13 Oct 2016

Rapa and its surrounding islets is a very remote place. It is almost 1500 from Tahiti, the main island in French Polynesia. This isolation together with other geophysical characteristics has resulted in the evolution of a highly unique flora and fauna. As for other islands of the eastern Pacific, there are no mammals, instead these are replaced by birds and a diversity of specialised plants, invertebrates and terrestrial molluscs. For a relatively small island (c.40km2) endemism is extraordinarily high. 3 birds, 100 molluscs, 31% of all plants and 67 Miocalles (beetles) species or subspecies only occur on Rapa (Meyer et al 2014). The island is an IBA and a KBA.

However, almost all of this flora and fauna is considered highly threatened. Believed to have been colonised as late as the 1500’s Rapa was the last island to be permanently occupied (by Polynesians) and while tremendous damage has been wrought it is perhaps this relatively recent human history that has allowed this unique fauna and flora to cling on. Reasons for these declines is a story replicated throughout the Pacific; habitat loss associated with the clearance of land for agriculture, uncontrolled fires and the introduction of invasive alien species that continue to degrade habitats, compete for resources and prey directly on native wildlife.

Rapa and the nearby Marotiri islets are the most important islands for seabirds in the Australs with the highest diversity for the archipelago, but also the greatest level of (sub-specific) endemism. The Rapa shearwater (Puffinus newelli myrtae) has recently been recognised as more closely related to the Endangered Newell’s Shearwater (formerly Little Shearwater Puffinus assimilis) which occurs in Hawaii, Rapa constituting an extremely distant population. Fregetta grallaria titan the local form of White-bellied Storm Petrel is also considered to have sub-specific differences due to its larger body size however, it’s had very little taxonomic attention and distinct characteristics including vocalisations may warrant a separate species.

The Endangered White-throated Storm Petrel (Nesofretta fuliginosa) is also present and, while there’s been no thorough seabird survey of Rapa for over 25 years, numbers then were perilously low. With the consistent effects of introduced rodents and feral cats, goats, rabbits, cattle and horses these populations will have continued to decline.

The endemic and Endangered Rapa Fruit Dove (Ptilinopus huttoni) is restricted to an estimated 10 forest remnants approximating 10ha each. Again feral populations of domestic stock particularly goats and cattle threaten the little habitat that remains and introduced rodents and feral cats compound these impacts through predation. These consistent pressures combined with the results of the Meyer surveys conducted in the mid to late 2000’s (Meyer et al 2014) have highlighted the habitat degradation that has gone on including extinctions particularly of land snails and Rapa is very much an ‘IBA in danger’.

These biodiversity values, along with an assessment that restoration is possible, have raised Rapa to the top of the BirdLife restoration priorities, along with the islands of Marquesas Archipelago, also in French Polynesia. The programme is already underway thanks to a generous grant from the David and Lucile Packard Foundation and planning is going ahead for the restoration operation to take place in 2018. But for this to happen Birdlife and its local partner SOP Manu must raise the near £100,000 necessary. So expect an ask coming out in the next 12 months.

While the cost of these restoration projects seems high, they provide the opportunity to save a unique place once and for all by removing the human introduced predators that have so decimated the nature of the Pacific. It is an opportunity we cannot fail to take up.
