Key Points: 
  • Eighty-four percent of pet owners say that their pets have a mostly positive impact on their mental health, similar to last year’s polling on the topic.
  • “It’s easy to overlook the role of pets when we’re talking about mental health,” said APA President Petros Levounis, M.D., M.A.
  • “From offering companionship and unconditional love to reducing stress and anxiety, pets can be invaluable sources of comfort and support.
  • One in five (18%) of those with pets said one or more of their pets was certified as an emotional support animal.

Harry Potter and the Disenchanted Wildlife: how light and sound shows can harm nocturnal animals

Thursday, February 8, 2024

Light and sound shows in parks can enthral crowds with their colour, music and storytelling.

Key Points: 
  • Light and sound shows in parks can enthral crowds with their colour, music and storytelling.
  • But unless they are well-located, the shows can also harm wildlife.
  • Research shows artificial light, sound and the presence of lots of people at night can harm wildlife.

A history of community opposition

  • While they often take place along existing walking trails, they attract huge crowds at a time when animals usually have the place to themselves.
  • Most of Australia’s mammals and frogs and many bird and reptile species are nocturnal, or active at night.
  • Light shows proposed for other wildlife conservation areas have also faced community opposition.

Light, sounds, action!

  • For example, it can change their hormone levels, and the numbers and health of their offspring.
  • Light also interferes with the ability of many species to navigate.
  • It masks the natural soundscape, making it harder for animals to find mates or hear the calls of their young.
  • It can also mask smells vital for an animal’s survival, such as that of food and predators.

Long-term harm

  • This cuts in half the time animals have to go about their life-sustaining activities and exposes them to greater risks when they do go out.
  • Light and sound shows are usually temporary – but can have major long-term impacts.
  • For example, males of the genus Antechinus (small marsupials) live long enough for just one short breeding season.

Find a better location

  • Organisers may have minimised impacts where they can, but evidence suggests the impact on wildlife will still be extensive.
  • Finding genuinely suitable locations should be done with care – and should avoid wildlife conservation areas altogether.

Monday, January 8, 2024

INDIANAPOLIS, Jan. 8, 2024 /PRNewswire-PRWeb/ -- In a stunning revelation at the Jurassic Mile® dig site, the international paleontology team from The Children's Museum of Indianapolis, Naturalis Biodiversity Center and University of Manchester successfully extracted colossal sauropod fossils for the Giants of the Jurassic™ portion of the Dinosphere® exhibit but also stumbled upon a remarkable find—an articulated Allosaurus fossil.

Key Points: 
  • "Other Allosaurus have been found with skin impressions in the past, but ours contains skin from parts of the body yet to be preserved.
  • The skin is leathery and has scales like the feet of chickens or the body of crocodiles."
  • This extraordinary discovery took place during the summer of 2020 but is just now on display for the public to see at The Children's Museum.
  • Over the last few years, the Allosaurus fossil was transported to Indianapolis, with different parts arriving in stages.

Our dogs can terrify (and even kill) wildlife. Here’s how to be a responsible owner this summer

Retrieved on: 
Tuesday, January 2, 2024

But many of us forget a key fact about our dogs: they are predators.

Key Points: 
  • But many of us forget a key fact about our dogs: they are predators.
  • The impacts of domestic dogs on wildlife aren’t well studied, and likely vary depending on the environment.
  • Nonetheless, there’s good evidence domestic dogs, when left unobserved, can have detrimental effects in the places they visit.

How dogs impact ecosystems


There are five main ways domestic dogs can negatively impact the natural environments they visit. These are:

  • For one thing, there’s little overlap between diseases common in domestic dogs and Australian wildlife.
  • There’s also little resource overlap, except perhaps in some areas where feral or semi-feral dogs live alongside dingoes.

Dogs can kill

  • While smaller animals such as lizards, gliders and possums are at higher risk, larger species such as koalas can also fall prey to dogs.
  • A study in Argentina’s Patagonia region details several cases of dogs decimating local penguin populations after gaining access to protected island areas during low tide.
  • Not to mention, dog attacks on wildlife can bring risk to dogs as well.

The impact of harassment

  • For example, certain threatened bird species will nest on the beach and find foraging opportunities based on the tides.
  • One dog forcing one bird to abandon this important activity may have a small impact.

Keep an eye on your furry pal

  • Training your dog to have general obedience – especially to come when called – is worth sinking considerable time and effort into.
  • This can save both your dog and any wildlife they may be after.
  • For instance, calling a dog away from a snake is one of the most effective ways of managing snake bite risk.
  • Investing in a long leash will allow your dog more freedom without putting wildlife at risk.
  • For small animals, even minor injuries from a dog will usually require veterinary attention.
  • It’s our responsibility to be respectful visitors when we’re out in nature, and to make sure our dogs are too.

'Foul and loathsome’ or jewels of the natural world? The complicated history of human-frog relations

Retrieved on: 
Saturday, December 30, 2023

Perhaps you came across one in your garden and wondered at its little hands, glossy skin and what looked very much like a contented smile.

Key Points: 
  • Perhaps you came across one in your garden and wondered at its little hands, glossy skin and what looked very much like a contented smile.
  • As our research has found, the history of human-frog relations is long and complicated – and not all of it is nice.

Why we love frogs

  • There is a rich history of people really loving frogs.
  • This is interesting, because many people much prefer mammals and birds over reptiles and amphibians.
  • Frogs are truly among the jewels of the natural world, unlike toads which – with their more mundane colours and “warty skins” – do not usually inspire the same sense of enchantment.

Dissecting human feelings for frogs


Yet relationships between people and frogs haven’t always been so positive. In fact, frogs occupy complicated places across cultures all over the world. In the Western tradition, the legacy of biblical and classical sources was both negative and longstanding. References to frogs in the Bible rendered them the instrument of divine anger as a swarming plague.

  • Frogs challenged early modern zoological taxonomies, moving between classification as serpent, insect or reptile.
  • In modern science, they sit in a branch of zoology, herpetology, that brings frogs together as “creeping animals” with snakes and lizards.
  • Italian scientist Luigi Galvani, for example, did experiments in the late 18th century on legs of frogs to investigate what he thought of as “animal electricity”.
  • In time, experiments with frogs moved beyond the laboratory into the classroom.
  • In the 1930s, schoolchildren were expected to find frogs and bring them to school for dissection in biology classes.

Recognising the fragility of frogs

  • From the frogs of Aesop’s Fables to the meme Pepe the Frog, we have projected our own feelings and frustrations onto frogs, and exploited them for science and education.
  • Frogs have also borne the brunt of our failures as environmental stewards.
  • In 2022, over 40% of amphibian species (of which frogs and toads are by far the largest group) were threatened with extinction.

Fewer insects hitting your car windscreen? Here's why

Wednesday, November 8, 2023

Every summer for almost the last 20 years, volunteers from the Kent Wildlife Trust and Buglife, both in the UK, have been tracking car number plates.

Key Points: 
  • Every summer for almost the last 20 years, volunteers from the Kent Wildlife Trust and Buglife, both in the UK, have been tracking car number plates.
  • Their inspections aim to register the numbers of flying insects hit by vehicles.
  • The results of the 2022 campaign showed a reduction, over fewer than 20 years, of 64% in the number of insects hit by cars.

The sixth mass extinction

  • In order to gain realistic measurements, the most rigorous research uses historical studies that track insect populations over decades.
  • In Germany, a 27 year-long study was published in 2017 showing that 76% of flying insect biomass has been lost within a wide network of natural spaces.
  • This study also showed a parallel decline in animals that eat insects, such as lizards, frogs and birds.

Why are there fewer insects?

  • They need the ground that we cover with cement, the increasingly scarce water that we pollute or divert, and the plants that we treat with pesticides.
  • Among other things, the number of airborne microscopic particles, which block their sensory organs and ways of communicating, are on the rise.
  • This weakens the vital biological relationships between all living things, and in turn threatens our very existence as a species.

Why are they so important?

  • It is therefore clear that they play many essential roles in sustaining life on Earth, most importantly that of pollinating plants.
  • 35% of the world’s food supply comes from plants that are pollinated by insects.
  • The UN Food and Agriculture Organsiation warns that if they were to disappear, food security would be at risk.

What can we do to protect them?


Large scale environmental problems cannot be solved by the actions of individuals. However, experience shows us that lots of small gestures can add up to achieve big results. Some of the things we can do are:
Support or work with projects that aim to raise awareness and protections for insects both in rural and urban areas. The aforementioned Kent Wildlife Trust and Buglife are good examples in the UK. In Spain we have the SPIPOLL project, the uBMS Citizens’ Butterfly Observatory and the Spanish Network of Biosphere Reserves’ Phenological Monitoring Programme.
Ensure that urban green spaces – as well as verges, roundabouts and other undeveloped areas – contain animal habitats and native flora which can provide breeding sites and refuge for insect species.
Refrain from using pesticides in private gardens or vegetable patches, and where possible in public green spaces. Limit the removal of “weeds” growing around ornamental plants, especially during flowering periods.
Consume food products made following good agricultural practices that value and promote organic farming and biological or integrated pest control.
Replace livestock pest control treatments with products that are not harmful to insects that help in the decomposition process.
Avoid introducing invasive plant or animal species, both in agriculture and gardening.
All of us, in particular educators, have an important responsibility to show both children and adults that insects are noble, vital and beautiful. Their declining numbers are an unprecedented problem, and our very survival as a species is at stake if we cannot reverse this trend.

Warming at the poles, especially the Arctic, has been three to four times faster than the rest of the globe.

Key Points: 
  • Warming at the poles, especially the Arctic, has been three to four times faster than the rest of the globe.
  • Climate models simulate this effect, but when tested against the past 40 years of warming, these models fall short.
  • This is a problem because these are the same models used to project into the future and forecast how the climate will change.

    Climate explained: why is the Arctic warming faster than other parts of the world?

Back to the future

  • For us, this means we can use Earth’s history to find out how well our climate models perform.
  • We can test our models by simulating episodes in the past when Earth was much warmer.
  • The advantage of this is that we have temperature reconstructions for these episodes to evaluate the models, as opposed to the future, for which measurements are not available.
  • Carbon dioxide (CO₂) concentrations ranged between 900 and 1,900 parts per million (ppm), compared with 415 ppm today.

Polar stratospheric clouds

  • In 1992 American paleoclimatologist Lisa Sloan suggested polar stratospheric clouds might have caused extreme warming at high latitudes in the past.
  • They are also called nacreous or mother-of-pearl clouds for their vivid and sometimes luminous colours.
  • This suggests polar stratospheric clouds could be one of the missing puzzle pieces.
  • In our research we use one of them and find that under certain conditions, the additional warming due to these polar stratospheric clouds exceeds 7°C during the winter months.

Implications for future projections

  • This suggests the standard climate models are better at predicting the future than the past.
  • Looking into the past is a way of broadening our horizon and learning for the future.

Giant sea lizards: fossils in Morocco reveal the astounding diversity of marine life 66 million years ago, just before the asteroid hit

Retrieved on: 
Monday, September 25, 2023

Was it a slow, inevitable decline, or did the end come quickly, driven by a sudden, unpredictable disaster?

Key Points: 
  • Was it a slow, inevitable decline, or did the end come quickly, driven by a sudden, unpredictable disaster?
  • Georges Cuvier, working in the early 19th century, was one of the first palaeontologists.
  • In part, his ideas were formed by study of a giant sea lizard, Mosasaurus, that lived and went extinct at the end of the Cretaceous.
  • Massive numbers of species disappeared near the end of the Cretaceous, rapidly, around the world, both on land and in the sea.

Cretaceous marine reptiles

    • Near the end of the Cretaceous, sea levels were high, submerging much of Africa underwater.
    • And an extraordinary diversity of marine reptiles sat atop the food chain: giant sea turtles, long-necked plesiosaurs – and the mosasaurs.
    • These beds, in what’s now Morocco, are today mined for fertiliser, in the process revealing an extraordinary marine ecosystem from the last days of the Cretaceous.
    • Far from declining at the end of the Cretaceous, marine reptiles – especially mosasaurs – evolved to become increasingly diverse.
    • This arrangement is unique among lizards, or even reptiles.

Resilience and adaptability

    • The reason so many mosasaur species could coexist was that they specialised, targeting different prey with different hunting strategies, avoiding competition.
    • The diversity of mosasaurs suggests the marine ecosystem was healthy and stable in the last million years before the Cretaceous period ended.
    • Seen on longer timescales, over millions of years, life shows remarkable resilience and adaptability, and a certain orderliness.
    • But even the most successful, well-adapted species is only one catastrophe away from extinction— one asteroid, one volcano, one ice age.
