Coral bleaching: The canary in the coal mine for corporate greed and environmental destruction

The Reef Check Foundation, Biosphere Expeditions’ partner for its coral reef citizen science work, has confirmed that a fourth global coral bleaching event is currently underway. This is an urgent wake-up call to the world, it being the second global mass bleaching in the past decade. It heralds a new reality of more frequent and severe bleaching events as ocean temperature records continue to be broken. Cycles of decline and recovery are normal for coral reefs, but bleaching events, which kill whole swathes of reef, are now so frequent that they are threatening coral reef survival around the planet.

The value of reefs

“A world without coral reefs will be a major problem for humanity”, explains Dr. Matthias Hammer, executive director of Biosphere Expeditions, the international citizen science NGO at the forefront of wildlife conservation, “because coral reefs have an estimated global value of €8 trillion each year, due to their contribution to the fishing and tourism industries, as well the coastal protection they provide. More than 500 million people worldwide depend on reefs for food, jobs and coastal defence.”

Fighting the decline across the world

For Biosphere Expeditions, these increasingly frequent and devastating bleaching events are nothing new, of course. The NGO, celebrating its 25th anniversary this year, has worked in coral reef conservation for decades, with a string of findings, achievements and successes.

In Oman, for example, Biosphere Expeditions’ citizen scientists showed that corals in Oman thrive in extreme conditions such as high salinity and temperatures, which would be considered marginal and highly challenging environments for corals in other parts of the world. Indeed, this remarkable ability may hold the key to coral survival in the face of global warming and its devastating effects on reefs across much of the planet. And further in Oman, Biosphere Expeditions’ citizen scientists gathered data for five years before fishing was banned in 2013 in two secluded bays in the coral-rich waters of the country’s Musandam peninsula in Oman by ministerial decree and the areas made MPAs. In parallel, Biosphere Expeditions ran an education and empowerment programme for Omanis resulting in historic first community-based reef surveys and the creation of Oman’s first reef protection NGO with two citizen scientist Omanis from this now playing a leading role in Oman’s reef conservation efforts.

In the Maldives, the NGO has been working since 2010, surveying for eight successive years an outstanding coral reef site called ‘Rasdhoo Madivaru’ until it was finally declared an MPA (marine protected area) by the Maldivian authorities in 2019. The site is both resilient to the worst effects of coral bleaching and harbours large megafauna such as sharks, manta rays, turtles and Napoleon wrasse. Besides this, Biosphere Expeditions in the Maldives has shown remarkable reef resilience and been instrumental in the creation of a local community reef surveying programme as well as education.

In Malaysia, coral reef expeditions to Tioman Island provided vital data on coral reef health and human-induced threats within the Tioman archipelago – data that were previously unavailable. This also helped build the foundation for ‘Cintai Tioman‘, a long-term programme to increase social and ecological resilience on the island.

Finally, in Honduras, Biosphere Expeditions assisted the Cayos Cochinos Marine Protected Area with managing and protecting their coral reefs.

Corporate greed & environmental destruction: reefs are the canary in the coal mine

“We must do all we can to protect the planet’s reefs”, says Hammer, “not just because they are a canary in the coal mine of how humanity treats this planet, but also because we owe it to the people who rely on reefs and to those who come after us not to wreck this planet, which sustains us and of which we only have one.” Hammer continues, “sure we can do our five Rs as individuals and people can come and help us as citizen scientists to fight the decline, which is utterly commendable, but in the end it will be about humanity reigning in corporate greed and destruction before it is too late. Because I concur that trashing the planet and hiding the money isn’t a perversion of capitalism, it is capitalism. This system is simply no longer fit for purpose, indeed it is at the root of the vast majority of environmental problems we are facing now.”

Evolution of Manatees in Florida

Published

on

manatee

Op-ed by Beth Brady, PhD, Senior Science and Conservation Associate, Save the Manatee® Club

Recent news articles and broadcasts have claimed that manatees are not native to Florida or only arrived on Florida’s west coast in the 1950s. These claims, based on limited anthropological records, point to where manatees were historically exploited by humans and assume that a lack of evidence means manatees were absent from certain areas. However, absence of evidence is not evidence of absence—it’s like looking for stars in the daytime; just because you can’t see them doesn’t mean they’re not there. Moreover, genetic and fossil evidence indicate manatees have been present in Florida for the last 12,000 years.

The Florida Fish and Wildlife Conservation Commission (FWC), which manages Florida manatee populations, has created a manatee timeline highlighting key dates and notable information about manatee presence in Florida (https://myfwc.com/education/wildlife/manatee/timeline/). Historical records suggest that manatees have been observed in Florida as far back as the 1500s, with some details presented by the Florida Fish and Wildlife timeline aligning with evidence presented in the publication.

Manatee species, such as the African manatee and the Antillean manatee, continue to be poached by humans (Marsh et al., 2022). As a result, these species are difficult to observe in the wild and may adapt by foraging at night to avoid human encounters (Rycyk et al., 2021). This behavior could help explain why historical Florida manatee populations that were hunted by humans are absent from middens and rarely mentioned in historical accounts.

Further, the publication only briefly touches on the paleontological record and genetic evidence, which indicate that manatees have existed in Florida for a much longer period. Fossil and genetic evidence reveal a rich history of manatees in Florida. Manatees belong to the order Sirenia, which includes the Amazonian, African, and West Indian manatee species. While Sirenian fossils have been found globally, only Florida and the Caribbean contain specimens from every epoch over the past 50 million years (Reep and Bonde, 2006). The modern manatee, as we know it, emerged in the Caribbean about 2 million years ago (Domning, 1982).

The evolution of manatees during the Pleistocene epoch provides valuable insights into how environmental changes shaped their distribution and genetic diversity. During the Pleistocene epoch (2.59 million to 11,700 years ago), there were roughly 20 cycles of long glacial periods (40,000–100,000 years) followed by shorter interglacial periods lasting around 20,000 years. At the start of these warmer periods, Caribbean manatees migrated northward with the warming waters (Reep and Bonde, 2006). Water currents and thermal barriers isolated these manatees from populations in Mexico and the Caribbean, leading to genetic divergence. Fossil evidence indicates that Trichechus manatus bakerorum lived in Florida and North Carolina about 125,000 years ago but did not survive the last glacial period, which began 100,000 to 85,000 years ago (Domning, 2005). This subspecies was eventually replaced by modern Florida manatees.

This evolutionary theory is further supported by genetic evidence. Research indicates that Florida manatees trace their evolutionary origins to Caribbean ancestors that migrated northward over the past 12,000 years (Garcia-Rodriguez et al., 1998). A 2012 study by Tucker et al. reinforces this theory, showing higher genetic diversity in manatees on Florida’s west coast compared to those on the east. Over time, core populations migrated northward, with some groups moving south and east along the Florida coastline before heading north along the Atlantic. This migration pattern left the west coast population with greater genetic diversity, while the east coast population retained only a smaller subset. These findings suggest that the founding population of Florida manatees—arriving approximately 12,000 years ago—originated along Florida’s southwestern coast, which became the center of the state’s manatee population (Reep and Bonde, 2006). The process of vicariance further supports this hypothesis; as geographic and ecological barriers emerged, they likely isolated the Florida manatee populations from their Caribbean ancestors. This isolation likely limited migration back and forth between regions, fostering the establishment of local populations in southwestern Florida.

manatee

Manatees are not only a cherished symbol of Florida’s natural heritage but also a species with deep evolutionary and historical ties to the region. In sum, despite recent claims questioning their nativity, extensive fossil and genetic evidence confirms that manatees have been present in Florida’s waters for thousands of years, with ancestors dating back over 12,000 years. We agree with the authors of the published article that protecting these iconic creatures and their habitats is essential to preserving Florida’s unique ecological identity for future generations
