First documented tiger shark mating hub identified by UH researchers
OLOWALU (HawaiiNewsNow) – A team of shark researchers from the University of Hawaii at Manoa have solved a longstanding mystery.
Biologists from the the Hawaii Institute of Marine Biology Shark Lab have identified the first-ever documented tiger shark mating hub.
Six years of acoustic tracking data led the team to pinpoint the area at Olowalu, Maui, leading them to new discoveries about the nature and timing of tiger shark mating and its correlation to Maui’s whale calving season.
This new finding challenges the understanding of tiger sharks as purely solitary animals.
“To our knowledge, no group mating site for tiger sharks has ever been identified. This paper adds an important piece to the puzzle of tiger shark reproduction,” said Carl Meyer, co-author of the study and principal investigator of the HIMB Shark Lab.
Researchers were able to show evidence that tiger sharks have a predictable seasonal gathering of mature males and females that coincides with humpback whale calving season in Hawaii.
Until this discovery, it was unclear how or if tiger sharks came together to reproduce or if mating was just a result of random encounters.
“Tiger sharks typically roam widely in what can seem like random patterns, so finding such a strong and consistent seasonal trend in their movements around Maui was unexpected,” said Paige Wernli, lead author of the study and a graduate student in the HIMB Shark Lab.
The years-long tracking data showed a predictable seasonal presence of both mature male and female tiger sharks at Olowalu, as well as physical evidence of mating activity.
The apparent mating hub happens during the time of year when humpback whale mothers and newborn calves arrive in the area.
The Shark Lab team says the correlation could mean that the sharks are positioning themselves near foraging opportunities, like vulnerable calves or placental falls.
“Mating and foraging on humpback whales may not be mutually exclusive,” Wernli said. “And both could influence tiger shark movement patterns in Hawaii.”
The tiger shark gatherings they observed were not dense but rather diffuse, spanning several kilometers over multiple months.
“This study expands our knowledge of tiger shark mating and challenges our conventional understanding of the term ‘gathering,’” said Meyer. “Together, the results suggest that both reproduction and food availability play key roles in shaping tiger shark movements in Hawaii.”
During the six-year study, the team was able to safely catch and implant transmitters in large sharks, then keep a vast network of underwater listening stations across the main Hawaiian Islands.
In the future, the Shark Lab team plans to use tags with cameras and other data collecting capabilities to document both their mating behaviors and shark-whale interactions.
This work was funded by the Hawaii Department of Land and Natural Resources and the Pacific Islands Ocean Observing System.

Hawaii Marijuana Legalization Bills Are Likely Dead For 2026 Session, Key Lawmakers Say – Marijuana Moment
A pair of Hawaii House bills aimed at legalizing marijuana in the state are effectively dead for the 2026 session, key lawmakers say.
Despite renewed hopes that the proposals—including one from House Judiciary and Hawaiian Affairs Committee Chairman David Tarnas (D) that would have put the issue of legalization before voters at the ballot—would advance this year, the sponsor and House Speaker Nadine Nakamura (D) say there isn’t enough support within the legislature to pass them this year.
“We’re the same members from last year,” Nakamura told the Honolulu Star-Advertiser on Friday, “and when we checked around, it didn’t sound like it would change anyone’s mind.”
“It’s just not a clear-cut ‘let’s do it,’” she said, adding that legislators “represent 1.4 million people” across the state, and “the constituencies are so different and they have to represent their constituencies.” The speaker said an informal head count of House lawmakers that leadership conducted last month revealed no clear signs that the general sentiment toward legalization had meaningfully changed.
“The feedback we were getting from members is that this doesn’t rise to the level of a constitutional amendment where we’re changing the way government operates,” Nakamura said. “This is more of an issue that should be addressed within the body.”
If the legislature agreed to advance the latest legalization plan, voters would see this on their November ballots:
“Shall the Constitution of the State of Hawaii be amended to:
(1) Authorize individuals aged twenty-one and older to use and possess personal-use amounts of cannabis; and
(2) Require the legislature to enact laws governing the use, manufacture, distribution, sale, possession, regulation, and taxation of cannabis within the State?”
If a majority of voters approved the ballot measure, cannabis legalization would take effect on July 1, 2027.
Tarnas, for his part, said he believes “the bill we put out this year addressed the concerns better than the bill last year.”
“So I think we got more votes from our internal polling but it’s not enough. So I still need to keep working on it,” he said. “I’m being courteously persistent. I think it’s incumbent upon me to continue the conversation in a productive way and a collaborative way to address the concerns of House members and the concerns of the chairs of those committees that have referred the bill.”
A Senate version of the legislation is still technically in play, but the same political dynamics on the House side would still complicate its path to passage if it were to cross over to that chamber.
Karen O’Keefe, state policies director at the Marijuana Policy Project, told Marijuana Moment on Monday that the Hawaii House “is not only blocking legalization against the wishes of those it represents, but it is also depriving voters of the transparency needed to hold their lawmakers accountable.”
“Last year, instead of allowing a floor vote on legalization, the House sent legalization back to committees it had already passed due to a lack of ‘consensus,’” she said. “This deprived voters of the knowledge of where their representatives stood. Now, it appears poised to kill a voter-referral and a legalization trigger bill, with no committee hearings or votes.”
“Hawai’i voters deserve a chance to legalize cannabis if their lawmakers are unwilling to do so. And they deserve to know which lawmakers are responsible for their continued criminalization,” O’Keefe said. “We hope the Senate has more respect for liberty, democracy, and transparency.”
State officials last month released a report on the potential economic impact of recreational marijuana legalization in the state, including revenue implications related to domestic and international tourism.
All told, researchers said survey data and comparative analyses indicate that Hawaii could see anywhere from $46-$90 million in monthly marijuana sales by year five of implementation, after accounting for a maximum 15 percent tax rate on cannabis products.
Hawaii’s Senate last year narrowly defeated a proposal that would have increased fivefold the amount of cannabis that a person could possess without risk of criminal charges.
Had the measure become law, it would have increased the amount of cannabis decriminalized in Hawaii from the current 3 grams up to 15 grams. Possession of any amount of marijuana up to that 15-gram limit would have been classified as a civil violation, punishable by a fine of $130.
A Senate bill that would have legalized marijuana for adults, meanwhile, ultimately stalled for the session. That measure, SB 1613, failed to make it out of committee by a legislative deadline.
While advocates felt there was sufficient support for the legalization proposal in the Senate, it’s widely believed that House lawmakers would have ultimately scuttled the measure, as they did last February with a legalization companion bill, HB 1246.
In 2024, a Senate-passed legalization bill also fizzled out in the House.
Last year’s House vote to stall the bill came just days after approval from a pair of committees at a joint hearing. Ahead of that hearing, the panels received nearly 300 pages of testimony, including from state agencies, advocacy organizations and members of the public.
Green signed separate legislation last year to allow medical marijuana caregivers to grow marijuana on behalf of up to five patients rather than the current one.
And in July, the governor signed another bill that establishes a number of new rules around hemp products in Hawaii, including a requirement that distributors and retailers obtain a registration from the Department of Health.
Lawmakers also sent a bill to the governor that would help speed the expungement process for people hoping to clear their records of past marijuana-related offenses—a proposal Green signed into law last April.
That measure, HB 132, from Tarnas, is intended to expedite expungements happening through a pilot program signed into law in 2024 by Green. Specifically, it will remove a distinction between marijuana and other Schedule V drugs for the purposes of the expungement program.
The bill’s proponents said the current wording of the law forces state officials to comb through thousands of criminal records manually in order to identify which are eligible for expungement under the pilot program.
Meanwhile, in November, Hawaii officials finalized rules that will allow medical marijuana dispensaries to sell an expanded assortment of products for patients—including dry herb vaporizers, rolling papers and grinders—while revising the state code to clarify that cannabis oils and concentrates can be marketed for inhalation.
The department also affirmed its support for federal marijuana rescheduling—a policy change that President Donald Trump ordered to be completed expeditiously but has yet to come to fruition.
Meanwhile, Hawaii lawmakers recently advanced a bill to allow qualifying patients to access medical marijuana at health facilities.

Regulators are also launching a series of courses designed to educate physicians and other healthcare professionals about medical marijuana as the state’s cannabis program expands.
The underlying medical marijuana expansion bill signed by the governor in late June, in addition to allowing more patients to more easily access cannabis, also contains a provision that advocates find problematic.
Before lawmakers sent the legislation to Green, a conference committee revised the plan, inserting a provision to allow DOH to access medical marijuana patient records held by doctors for any reason whatsoever.

Researchers track risk of avian malaria to future of Hawaii’s native birds
HONOLULU (HawaiiNewsNow) – A new study published Tuesday is helping scientists understand why avian malaria is present in almost all of the same places that mosquitoes are found in Hawaii.
Research out of the University of Hawaii at Manoa suggests that avian malaria can be transmitted by nearly all forest bird species in the state.
The study found that 63 out of 64 sites across the islands had avian malaria, including areas with diverse bird communities.
“Avian malaria has taken a devastating toll on Hawaii’s native forest birds, and this study shows why the disease has been so difficult to contain,” said Christa Seidl, mosquito research and control coordinator for the Maui Forest Bird Recovery Project, who conducted this research as part of her PhD at the University of California Santa Cruz.
The disease, which is caused by a parasite, poses a serious risk of population declines and even extinctions in native Hawaiian honeycreepers.
Seidl says the key to protecting native birds from avian malaria is controlling mosquito populations.
“When so many bird species can quietly sustain transmission, it narrows the options for protecting native birds and makes mosquito control not just helpful, but essential,” Seidl said.
Studies have shown that iʻiwi, or scarlet honeycreepers, had a 90% mortality rate if infected with avian malaria.
The akikiki, a Hawaiian honeycreeper native to Kauai, is now considered extinct in the wild.
“We often understandably think first of the birds when we think of avian malaria, but the parasite needs mosquitoes to reproduce, and our work highlights just how good it has gotten at infecting them through many different birds,” Seidl said.
The study analyzed blood samples from more than 4,000 birds across Kauai, Oahu, Maui, and Hawaii Island.
Researchers found that both introduced birds and native birds often had overlapping levels of infectiousness, meaning both groups can spread the disease.
The broad ability of avian malaria to spread likely explains why the disease is so prevalent across the islands.
Seidl and the Maui Forest Bird Recovery Project are part of Birds, Not Mosquitoes, a group that aims to tackle mosquito control for the future of Hawaiian bird conservation.
