Most people’s encounters with lemurs have occurred through their representations in popular children’s media, like Zoboomafoo or Madagascar. However, most people don’t know that lemurs play an important role in forest renewal and that they’re currently in grave danger from climate change.

In my home country of Madagascar, there is an amazing array of creatures that are not found anywhere else in the world. Madagascar is a biodiversity hotspot, and approximately 90 per cent of plant and animal species on this island are endemic.

Among them are lemurs, a group of primates that are not only the flagship symbols of the island’s fauna, but also one of the key players in the health and stability of Madagascar’s ecosystems because they do the very important work of dispersing seeds.

I am a primatologist who researches the interactions between infant-and-mother lemur dyads in wild. Their bond is a reminder of what we stand to lose, as it shows care, learning and viability. When forests disappear, so does this fragile bond, and a whole way of life we can never replace.

Lemurs’ habitats and survival are increasingly being threatened by human activities such as deforestation, forest resource exploitation and hunting. There is an urgent need for conservation projects that involve local communities in preserving Madagascar’s unique biodiversity.

Charismatic animals

Due to their charisma, media attention and their biological significance, lemurs attract tourists and researchers to Madagascar. The viability of lemurs is essential to the island’s future, both economically but especially in terms of protecting biodiversity. As they eat fruits from trees like ebony, mammea and wild coffee and then scatter seeds through their droppings, they help new plants grow.

Among the 105 lemur species of Madagascar, Propithecus candidus, commonly known as the silky sifaka, is one of the most endangered species. Only around 250 of them are currently living in the wild.

As their name implies, silky sifakas have visually striking long white hair, and they can only be found in the misty, mountainous rainforests of northeastern Madagascar.

Silky sifakas are primarily active during the daytime, and can travel very quickly through the trees by vertically clinging to them and leaping from tree to tree using their powerful legs. They have highly specialized diets consisting of leaves, flowers and fruits like Diospyros pervilleana, a native ebony species from Madagascar.

Observing mothers and infants

I have spent 10 years studying and following lemurs daily. During my fieldwork in northeastern Madagascar, I closely observed how deforestation and habitat fragmentation affect silky sifaka females and their young.

I studied these females during their lactation season in three different forest contexts: Marojejy National Park (a mostly untouched primary rainforest), Makira Natural Park (a mix of old-growth and re-generating forest) and Anjanaharibe-Sud Special Reserve (known as COMATSA-Sud, a primary forest with heavily degraded areas).

At each forest, the forest canopy, which provides both shelter and food for the lemurs, measured above 10 metres at all sites, but was semi-open, which is a sign of habitat degradation. A semi-open canopy allows more light to permeate the forest canopy, but it also exposes animals to predators and decreases the quantity of high-quality food.

Mothers’ movements and behaviours

One clear difference between the three sites is how mother–infant pairs move and use space. In Marojejy, where the forest is more continuous even if the canopy is partly open, mothers and babies stay within fairly fixed areas, following the same paths and resting spots.

But in places like Makira and COMATSA-Sud, where the forest is broken up into separate patches, mothers have to travel farther and more unpredictably, moving between these isolated patches. This extra travelling causes them to burn more energy and face higher risks from predators and hunters.

These differences show that fragmentation doesn’t just affect food availability, but also changes how these lemurs move and survive.

Forest fragmentation affects lemurs’ social behaviour and grouping patterns to deal with low food availability. It also impacts their health and development; a poor diet causes malnourishment in the lemurs.

Poor nutritional quality

While the food availability for silky sifakas in northeastern Madagascar during the lactation season is relatively abundant, it is of low nutritional quality.

This leads to increased stress and competition as dominant lactating females, desperate to feed their infants, attack subordinates to accumulate more nutrients to produce higher quality milk.

As offspring start to feed on non-milk foods, the poor nutritional quality of available plants after weaning can lead to poor health and stunted growth.

Engaging the community

The decline of lemur populations, particularly silky sifakas, shows the need for urgent conservation action. Continued monitoring — as well as sustained support and funding for Malagasy scientists — is crucial for long-term lemur and biodiversity conservation.

When it comes to the effects of human activity, this decline — habitat fragmentation, global climate change and deforestation — is the result of large-scale activites such as extraction, tourism and state infrastructural development.

Education and awareness campaigns are crucial, both in Madagascar and internationally, to inform people about lemurs’ habitat needs and what can be done to prevent their extinction.

Conservation will never be successful without building an appreciation of the environmental, cultural and economic value of lemurs and the forests they inhabit.

Canadian Prime Minister Mark Carney has made establishing east-west energy corridors a priority for Canada. He suggested that such corridors would include new oil and natural gas pipelines, designed to reduce dependence on the United States.

Energy and Natural Resources Minister Tim Hodgson has gone even further in pushing for subsidization of carbon capture and storage projects that would effectively underwrite the long-term continuation of the fossil fuel industry at taxpayer expense.

While there might be short-term political reasons for backing fossil fuels, such an approach goes against Canada’s long-term interests. Prioritizing fossil fuels undermines the country’s commitments to reduce emissions and takes away the investment needed for it to realize its potential to become a green energy superpower.

Creating energy corridors is in the national interest, and would allow Canada to take full advantage of its abundant and diverse energy and mineral resources. The government also needs to be involved, as the corridors are interprovincial and will require substantial investment. However, the government has limited resources and so Canada must think strategically about its priorities for such corridors.

Canadian taxpayers should not be subsidizing an already lucrative oil and gas industry. Instead, the federal government should prioritize funding clean energy supply solutions.

Oil and gas subsidies

Canadian governments have long faced opposition to building new pipelines. The provinces of Québec and British Columbia and many First Nations have strongly opposed new pipeline proposals. More recently, there is some signs of softening under the duress of U.S. tariffs.

Even if such shifts are lasting, it’s for the private sector to step up and invest into these projects. Previous federal investments, such as the Trans Mountain pipeline (TMX), were reflections of the private market’s unwillingness to invest in pipelines because they are bad investments. The 2024 Parliamentary Budget Office report estimated that selling the TMX would result in a loss.

There are reasons to question the soundness of fossil fuels on a purely financial basis. A 2022 Parliamentary budget office report found that climate change reduced GDP by 0.8 per cent in 2021, or around $20 billion. This number is expected to rise to 5.8 per cent per year by 2100 (or $145 billion in 2021 dollars).

By contrast, from 2017 to 2021, federal, provincial and territorial governments received an average of $12 billion annually in revenues from the the oil and gas industry.

The gap between the costs and benefits is only going to increase over time. The costs cut across all aspects of life, including food security, health care, global instability and threats to coastal cities due to sea level rise.

On the other hand, every dollar invested in adaptation today has an estimated return of $13-$15.

Furthermore, a recent study indicates a likely glut in global natural gas markets, and the future prospects for oil are equally questionable. For example, one of Canada’s target markets, Japan, has been reselling its liquefied natural gas imports to other countries, suggesting the glut of oil and gas is likely to continue as cheaper producers, including those in the Middle East and Southeast Asia, who are cheaper and closer to consumers, flood the market.

Cheaper and closer oil producers are also flooding markets in anticipation of declining prices.

There are important opportunity costs of investing money in fossil fuels that could otherwise be invested in the clean energy economy. When new technologies arise, there is a limited window of opportunity for global competitors to enter into an emerging industry.

In light of the shift to electric vehicles, heat pumps and artificial intelligence, it’s clear that energy demand is bound to increase significantly in Canada in the coming years. Canada can become a global competitor, but only if it enters the race now, while the window is open.

An East-West clean energy system

Solar and wind prices have declined by 83 per cent and 65 per cent respectively since 2009. However, they suffer from the fundamental issue of intermittency; the sun is not always shining and the wind isn’t always blowing.

While battery prices are declining, they remain an expensive solution. An easier solution is at hand: Canada’s hydroelectric resources. Québec, B.C. and Manitoba have abundant hydro resources that can reduce energy costs throughout the rest of the country.

Alberta and Saskatchewan have potential for significant geothermal power generation. Ontario and the Atlantic provinces could contribute wind and solar. Trading electricity through an integrated national grid increases the investment capital and reduces the need for batteries while diversifying the energy mix.

But we need an east-west electricity market to make this happen.

An east-west grid would reduce the need for every province to run its own power generation system. Creating a pooled market would allow provinces to trade electricity, giving consumers more choice and investors a larger market and potential return on their investment.

More valuable still is the fact that electricity capacity has to be built for the few peak hours and seasons. But most of the time demand is well below full capacity, such as the middle of the night or early summer, when neither heat nor air conditioning is needed in many areas. As peak times and seasons vary across the country, Canada can reduce overall costs by trading the electricity in the lowest cost producing province at a given time to where it’s needed in the other.

By locating some of the new clean energy in First Nations, Canada can also move reconciliation forward. There is potential for a win-win situation whereby Canada increases renewable energy generation while creating new jobs and income for First Nations wherever feasible.

The first step is for regulatory reform across the provinces to support a Canada-wide electricity market, and to provide the funding for the massive infrastructure investment required to connect provincial grids. This would be a federal investment with incredible long-term payoffs for employment, taxpayers and future generations.

Following this plan could truly make Canada an energy superpower on the right side of the energy transition, create thousands of jobs and give the country a global competitive edge — all while helping to save the planet in the process.

The orgasm gap — the consistent finding that men who have sex with women have more frequent orgasms than women who have sex with men — has been shown in study after study of cisgender, heterosexual participants.

The gap is a big one: Based on a recent Canadian study, approximately 60 per cent of women and 90 per cent of men reported reaching orgasm in their most recent sexual encounter.

In sexually diverse samples (samples that also include women who have sex with women and men who have sex with men), the pattern becomes more nuanced but still supports a gendered orgasm gap.

Research has shown that the gap in orgasm frequency is reduced (in other words, there is more equal orgasm frequency) in women who have sex with women (about 75 per cent), and this rate is significantly higher than in women who have sex with men (about 62 per cent). However, men as a group — regardless of who they were having sex with — still had significantly higher orgasm frequency (85 per cent) than women overall (63 per cent). Women are orgasm-disadvantaged overall and especially when they have sex with men.

Mind the gap

How far-reaching is the orgasm gap and what factors might be standing in the way of orgasms for all? We — a team of researchers and science journalists from the podcast Science Vs — examined orgasm frequency in a large diverse sample that included sexual (such as lesbian) and gender (such as trans) minorities and majorities, as well as racialized participants (there were no significant results with analyses focused on sexual orientation or race).

The good news? We found that many people overall were having lots of orgasms — about two-thirds reported having orgasms almost or every time they engaged sexually.

The not-so-great news? The orgasm gap persisted: cis men overall reported the highest orgasm frequency compared to women and gender minorities (who did not differ significantly from each other). In addition, we found that participants of all genders who engaged sexually with women reported significantly more frequent orgasms than those who engaged sexually with men. So being partnered with a woman is associated with an orgasm advantage.

More not-so-great news was that about 17 per cent of participants reported almost never or never having orgasms during sex and that there were many factors preventing orgasms in participants. For cis women, psychological barriers — such as insecurities, mental health struggles and distractions — were prominent, as were sexual obstacles (like not receiving adequate stimulation), difficulties inherent in having orgasms (for example, they take too long and require too much effort) and not knowing why orgasms are difficult for them to have.

Closing the gap

So why does the orgasm gap exist and persist? One main reason is that broad sociocultural norms prioritize men’s sexual pleasure over women’s. Indeed, these norms develop from the traditional (heterosexual, western) sexual script that defines the end of sexual activity as male orgasm; importantly, women’s adherence to this script has been associated with lower sexual satisfaction.

Another is that mainstream media feeds into narratives of sexual expectations based on gender, such that portrayals of women who do not have orgasms are much more — even readily — acceptable than portrayals of orgasmless men. This inequality is played out in sexual encounters, perpetuating the gap and contributing to complacency in addressing it.

But there is hope: Heterosexual men’s motivation to bring their partner to orgasm and their intentional incorporation of sexual activities that increase the chance of orgasm for their partner — such as clitoral stimulation and oral sex — can help narrow (and even eradicate!) the gap. Women’s own degree of familiarity with their partner has also been shown to be help narrow the gap. Higher familiarity (think of a long-term situationship as opposed to a casual hookup) was associated with higher orgasm frequency.

The simple act of prioritizing women’s orgasm — captured with an easy-to-remember phrase of “she comes first” — may be all that is needed to substantially narrow the orgasm gap.

The Canadian Armed Forces (CAF) is making headlines. But not, as they probably hoped, for the renewed recruiting efforts they’re about to launch. Instead, they are once again confounded by a far-right scandal.

The latest episode is the arrest of four CAF members and ex-members. Three of them have been charged with taking concrete steps to facilitate terrorist activity and possessing prohibited firearms. A fourth man was charged with possession and storage of prohibited firearms and devices.

The crew had allegedly been under surveillance by the federal government’s Integrated National Security Enforcement Team since 2021, most likely when equipment, weapons and ammunition began to go missing from military installations. The weapons were finally seized in January 2024, some in the personal vehicle of one of the suspects, but the group remained free for another 18 months.

Charges against Canadian Army members in anti-government terror plot raise alarms about right-wing extremism

As is usual with these types of efforts, a certain degree of amateurism was present at multiple stages of the alleged scheme, which may have developed on the fly. The idea that a micro-militia might successfully seize and hold territory in Canada is far-fetched at best.

Recruitment efforts for the suspected mission, complete with propaganda and self-aggrandizing pictures of military training, took place on, you guessed it: Instagram. (We won’t publish the name of the account.)

It might be pointed out that any large organization like the CAF inevitably represents a microcosm of society, meaning that it can’t be expected to be free of various forms of undesirable behaviour, including political extremism. But this “rotten apple” theory of far-right extremism in the CAF falls somewhat short of explaining the situation.

Not just a ‘few rotten apples’

First, the rotten apples seem too numerous. Just days before the recent arrests, the CAF announced on July 3 it was investigating the participation of other soldiers in a private Facebook page named the “Blue Hackle Mafia.” The page disseminated openly racist, homophobic, misogynist and antisemitic content.

These events point to a phenomenon difficult to measure within western countries, even though it’s very real. The penetration of ideas associated with the far right within the military and law enforcement agencies is currently happening. Whether more or less structured, the emergence of underground small groups are more or less ready to “take action.”

Second, previous reports have identified a general laissez-faire approach within the CAF regarding far-right activities. In a 2022 independent report commissioned by the CAF, the presence of white supremacist and other far-right ideologies was identified not only as a growing problem for the Army, but also one that was not being addressed.

Similar conclusions were reached in the 1997 report on the behaviour of Canadian soldiers in Somalia, which had explicitly recommended that “the Canadian Forces establish regular liaison with anti-racist groups to obtain assistance in the conduct of appropriate cultural sensitivity training and to assist supervisors and commanders in identifying signs of racism and involvement with hate groups.” In other words, neither the concern nor the awareness is news.

Affinity between far right and military

At the root of the problem is a peculiar affinity between most forms of far-right ideologies and military or paramilitary/policing organizations.

It’s absurd to simply paint such organizations as inherently far right in their nature, of course. But strict authority structures and notions of defence, fellowship, honour — as well as the projection of power through physical strength and training and the accompanying symbolism of weapons, fatigues, uniforms and campaign-like deployments — are all very appealing to far-right extremists.

This nexus has been amply documented and leads to multiple practical implications: extremist groups trying to recruit active or retired soldiers; soldiers joining existing groups or setting up their own; veterans joining existing groups or creating their own, like the founders of Québec’s La Meute; professionally trained lone wolves, like Correy Hurren, who attempted to “arrest” Prime minister Justin Trudeau at Rideau Hall in 2020)

Members of extremist groups also routinely try to join the military to benefit from training, which elevates their standing within the group.

Military, former and active, and law enforcement members are to be found in multiple “militia” groups like the Three Percenters, the Proud Boys, the Oath Keepers, Diagolon and the Boogaloo movement, for instance. Some are overtly anti-government and/or anti-system, like the Veterans 4 Freedom or The Base.

Far-right demons

It may sound strange to think of military personnel or veterans getting involved or creating an anti-government movement when they’ve served under the flag sometimes for decades. The apparent paradox quickly disappears once we understand the manifold individual motivations that underpin their actions.

They range from the feeling of having served a timourous government that failed to make proper use of the Armed Forces at its disposal. The absence of deployments to theatres of conflict also generates frustration among some in search of military adventure.

A lot of young men are quickly bored with exercises that never satisfy their expeditionary spirit. The role of camaraderie, of group dynamics based on mutual aid, honour and the presence of danger, as well as mental health issues, must not be overlooked. Not to mention the idea, strong in some units, of defending a singular idea of a “fatherland” endangered by government contempt and inaction.

What is striking in the light of the recent charges in Québec is not so much the racist and anti-semitic ideological ideas allegedly held by the accused group members. It’s the primacy given to a patriarchal ideology that explicitly targets women and gender. Fascination with Russia and the war in Ukraine waged by Vladimir Putin is also palpable.

In short, the CAF is still wrestling with far-right demons, though in a new context of social media acceleration and global loss of confidence in democratic institutions. The situation has a high potential to undermine confidence in Canada’s Armed Forces at a time when geopolitical tensions are calling for a strengthening of its military arsenal, and first and foremost, our military human capital.
