Palm trees in Vancouver? Florida’s climate in Burnaby? Plant fossils suggest region once had a warmer climate

There was a time when Burnaby Mountain, and the areas around it along B.C.’s south coast, was a warmer, less mountainous region where palm trees grew, according to new research that identified plant fossils unearthed at the site more than 50 years ago.

When Simon Fraser University was being built in the late 1960s, paleobotanist Rolf Mathewes was an undergraduate, and he helped gather dozens of plant fossils at a deposit exposed by the construction site. The fossils date back to around 40 million years ago.

SFU then locked the specimens in cabinets, where they remained largely untouched for decades.

Now a professor at the university and at the twilight of his career, Mathewes set out to revisit the plant fossils he helped collect.

“I thought, before I retire, I should really publish something on these fossils. They’ve never been published and never really been studied,” said Mathewes.

Mathewes and his research team verified the collection contained a mix of subtropical and temperate forest elements, giving clues about Burnaby Mountain’s climate in the distant past.

The findings were published in the International Journal of Plant Sciences this month, looking into the plant fossils that date back to the late Eocene period. The Eocene lasted from 55.8 to 33.9 million years ago and is known for its warmer climate.

Palm trees once in B.C.?

Mathewes says a significant fossil in the collection was a palm leaf fragment. Palm trees can still be planted in B.C., but they can no longer thrive in the region.

“If you wanted to match what kind of climate they’re telling us was here, the best match is somewhere around Cape Fear on the East Coast of the United States,” said Mathewes.

Mathewes says a global cooling period that followed the Eocene era allowed for the palms in the area to be slowly replaced by temperate trees like elms and sweetgum.

“The palms can tolerate it here, but it’s not warm and tolerant enough to make it into the forest.”

The team also identified a hydrangea flower and a flower of an extinct plant related to the basswood, which is native to Eastern North America.

“Some of the things that turned up were amazingly surprising … That includes some flowers and seeds of plants that don’t grow here and are only found in either Asia or in eastern North America.”

Mathewes also notes the Burnaby Mountain region resembled a floodplain during the Eocene.

“It was a sea-level plain near the ocean with rivers and ponds and marshes on it, and that’s where the fossils were produced,” he said.

‘A glimpse of … what things might look like’

Kendra Chritz, an earth sciences professor at the University of British Columbia who was not involved in the study, says finding the palm in the fossil locality gives further evidence of Metro Vancouver’s climate being warm and humid around that period.

“If you think about places where palms grow naturally now like California, Florida or Mexico, imagine something like that but in British Columbia. It’s very warm, very wet and diverse,” Chritz said.

Chritz says it’s important to study periods like the Eocene to help understand today’s changing climate. She says the Eocene period had high levels of carbon dioxide, which could inform today’s increasing levels.

“This kind of gives us a glimpse of maybe what things might look like, but we also have to remember that this is well before we existed.”

Chritz says human activities put a different context to a warming climate, when animals and plants cannot move around and adapt as easily as they did in the distant past.

Mathewes says he’s happy to have revisited the fossils he helped collect decades ago. The study is dedicated to his late mentor who oversaw the excavation, Robert C. Brooke.

“I’m glad I managed to finally finish analyzing the story with the help of my colleagues,” Mathewes said.

“I should have done it years ago, but I was tied up.”

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
