Photographs on the Arkive website  have helped two naturalists who had never met and work around 200 miles (310 kms) apart to identify two previously unrecorded species of one of Earth’s oldest flowering plants: the magnolia.

In 2010, Roberto Pedraza Ruiz gave Arkive a series of animal and plant photos he had taken in a life-rich cloud forest within eastern Mexico’s Sierra Gorda Biosphere Reserve. One of the photos he donated was identified as being the magnolia, Magnolia dealbata, classified as Endangered on the IUCN Red List.

But the image raised questions for Dr José Antonio Vázquez, a botanist at the University of Guadalajara, when he came across it during a search of Arkive’s 16,000 free-to-view online flora and fauna fact-files.

It was this image that first raised questions. It is now identified as a Magnolia rzedowskiana flower.

As Roberto explains: “For Dr Vázquez, the specimen in the photo seemed unusual and he requested that I sent him more pictures. So I made several more trips to the cloud forest, documenting the flowers and fruits of the trees until finally receiving confirmation that I had photographed not only one but two completely new species of magnolias.”

Two new species of magnolia discovered

The first of the finds, originally identified on Arkive, has already been documented and has been given the name Magnolia rzedowskiana, after Dr Jerzy Rzedoswski, Mexico’s most eminent botanist who has collected and documented over 50,000 species and celebrating his 90th birthday this year.  A description of the second specimen is about to published and will be named Magnolia pedrazae, after Roberto.

He says: “This is without doubt the highest honour that a conservationist and nature photographer can receive. It means that this incredibly special tree – an endemic of the Sierra Gorda and product of an evolutionary process that spans millennia – has become part of the family.”

Lucie Muir, Director of Wildscreen, added: “We were absolutely thrilled when Roberto told us that a new species of magnolia had been identified because of botanist looking through the images on the Arkive website. It’s amazing that new species are still being discovered and that on this occasion Arkive was part of the discovery story.”

Grupo Ecológico Sierra Gorda

The use of the Pedraza name is especially apt as it was Roberto’s parents who started the grassroots movement which led to the creation of the Grupo Ecológico Sierra Gorda (GESG) to look after a section of the eastern Sierra Madre where the high peaks, rain shadow, remoteness and latitude mean biodiversity is especially rich.

Roberto grew up in the region and soon turned to photography as a way of documenting and sharing the area’s biological wealth and GESG’s work to protect it.  It was during one of his GESG expeditions in 1996 that Roberto found loggers at work in the cloud forest where the new species of magnolia grow.   After he raised the alarm, 40 friends clubbed together to buy the land and halt the operation – so saving a habitat where ancient oaks and cypress reach heights of 130 feet (40 metres), their limbs draped in dense mats of moss, ferns, orchids and bromeliads; and a place where he has photographed many rare or previously unrecorded life-forms, including jaguars, pumas and margays and a new family of molluscs.

Roberto says: “These discoveries highlight the importance of protecting sites with high biological value, giving ecosystems and species refuges from human activity, spaces where they are protected from humans’ ever-increasing demands for land and ecosystem services. If steps had not been taken to protect them, these species and others may have disappeared before we even learned of their existence.”

In honour of Mother’s day today in the U.K., we have come up with ten of the most loving mums in the animal kingdom.

‘Darling would you stop pressing your paw so hard into my back…’

Photo of polar bear swimming with cubs

Although this lucky polar bear mummy gets to sleep through birth, it’s not all smooth sailing. She has to nurse and care for her cubs for 2.5 years, during which she has to provide food and teach them how to swim. As you can see, she gives them a helping hand every now and then.

‘Please stop fidgeting sweetie’

Great crested grebe with chick

This great crested grebe mother gets help from her partner in incubating and rearing her young, and she only has to look after them for less than 3 months. You may think she has an easy ride, but she is a very attentive mother and carries her stripy chicks around on her back. No need for a buggy here!

‘Wait your turn, you have to learn to share’

Female cheetah with suckling cubs

Cheetah mums have a lot on their mind. Until the cubs are 8 weeks old, they have to leave them alone in a lair while they go hunting. This is a necessary trip but the risk from the many predators around means the death rate of young cheetahs is very high. Thank goodness we can just go to the supermarkets!

‘I do wish you’d cleaned your feet’

Newly hatched Nile crocodile gently held in adult's jaws

This may be a big surprise to you, but the female Nile crocodile is a very attentive parent and after laying around 60 eggs will cover the nest with sand and guard it for around 90 days. Amazingly, her powerful jaws can be used incredibly gently, and she gathers the hatchlings in her mouth and transports them to water. There’s certainly no padding in this pram!

‘Try and keep up little one’

Female blue whale with calf

You won’t be jealous of the blue whale mum. She has to be pregnant for 10-11 months, and has to feed the calf 100 gallons of her fat rich milk during the nursing period! This is one demanding kid

‘In an hour I can drop you at the crèche, I’ve got to get my feathers done’

Sandwich tern with chick

We are not the only ones to come up with child daycare, as the sandwich tern has also had this idea. Once hatched, the young may gather together in a group, called a ‘crèche’, which is attended by one or several adults. Smart mothers!

‘Lunch time is over now honey, time to go and play’

Africam elephant suckling

If you thought the blue whale pregnancy was long, the African elephant definitely beats it! This poor mum has to be pregnant for nearly 2 years, and has to keep looking after the young for several years after that. Luckily other females in the group help out, known as ‘allomothers’. Every mum needs a break once in a while!

‘Don’t spike your sister!’

Hedgehog with young

Hedgehog mothers are truly single parents, as they are left alone to care for 4 to 5 spiky babies! Luckily they are born with a coat of soft spines to protect the mother during birth. They don’t stay baby soft for long though, as a second coat of dark spines emerges after about 36 hours.

‘You are getting so big now my dear!’

Giant panda female suckling infant

For such a large mummy, it is rather shocking to find out that the giant panda gives birth to a baby that is only 0.001 percent of her own weight! This caring mother will remain with her baby until it is about two years old or sometimes even older. But how could a mother resist when her baby is this cute!

‘Hang on tight my little orange!’

Bornean orang-utan female with infant

The Bornean orang-utan mother is probably one of the fittest around. She will carry her baby constantly for the first two to three years of their life and will take care of it for at least another three years! This mother definitely is a ‘supermum’!

Let us know if you can think of any other caring animal mums!

Happy Mothers Day to all the mums out there!
